[0041] The material sorting device 100 of this embodiment may include a frame 10 and a blowing assembly 20 and a pushing assembly 30 disposed on the frame 10 .

[0042] An embodiment of the present disclosure provides a material sorting device 100, comprising: a frame 10, which includes a plurality of mounting parts arranged along a material throwing path; a blowing assembly 20, mounted on one of the plurality of mounting parts, the blowing assembly including a jet part, the jet part being used to blow an air flow toward the material to be rejected to remove it from a plurality of materials; and a pushing assembly 30, mounted on another of the plurality of mounting parts, the pushing assembly including a push plate, the push plate being used to push the material to be rejected to remove it from a plurality of materials.

[0043] In some embodiments of the present disclosure, the material sorting device 100 is applied to a material sorting machine 200 , and the material sorting machine 200 may include a conveying mechanism 210 , a detection mechanism 220 , and the material sorting device 100 .

[0044] The material sorting device 100 may include a push-up assembly 30 and a blowing assembly 20. The material sorting device 100 may also include only the push-up assembly 30 without the blowing assembly 20. In this embodiment, the material can be sorted only by the push-up assembly 30.

[0045] The materials described in the present disclosure may be ores, stones, or other materials requiring separation and sorting, wherein the materials to be removed may be ores, stones, or other materials requiring separation and sorting that require separation by a push assembly or a blow assembly, and the materials to be removed may be desired materials or undesired materials, as long as the materials can be sorted. The mounting portion may include a fixed bracket for the blow assembly and a fixed bracket for the push assembly.

[0046] The material sorting device 100 of this embodiment includes a frame 10 and a blowing assembly 20 and a pushing assembly 30 arranged on the frame 10. In addition, Figure 1 also shows a portion of a conveying mechanism 210 for conveying materials, wherein the conveying mechanism 210 can be a material transportation device such as a conveyor belt. During operation, materials of different sizes are transported by the conveying mechanism 210 at a certain speed in the longitudinal direction, and when they are transported to the discharge point, they leave the conveying mechanism 210 with an initial velocity in the longitudinal direction and fall along a parabola. Here, the solution disclosed in the present invention defines the path along which multiple materials fall along the parabola as a material throwing path a. Based on this, the blowing assembly 20 and the pushing assembly 30 can be arranged in sequence on the frame 10 along the material throwing path a. In this embodiment, the blowing assembly 20 is arranged on the upper part of the frame 10 relative to the pushing assembly 30, and is closer to the discharge point of the conveying mechanism 210 in the horizontal direction. Here, it is defined that the blowing assembly 20 is located upstream of the ejecting assembly 30 along the material ejection path a, that is, the material falling from the discharge point first passes through the position corresponding to the blowing assembly 20 and then passes through the position corresponding to the ejecting assembly 30.

[0047] In one embodiment, the above-mentioned blowing assembly 20 of the present disclosure may include an air jet portion 21 capable of ejecting gas, and the air jet portion 21 may include components such as a nozzle 211, for ejecting gas toward the material to be rejected that falls along the material ejection path a, so that the material to be rejected is blown by the gas and changes its motion path, thereby removing the material to be rejected. Similarly, the above-mentioned pushing assembly 30 may include a push plate 31, and as an example, the push plate 31 can be processed into a push plate that rotates relative to the hinge portion. In operation, the push plate is driven by an internal cylinder 331, so that it can swing out toward the material ejection path a and contact the material to be rejected, thereby pushing the material to be rejected to change its motion path, thereby achieving the purpose of removing the material to be rejected.

[0048] Referring to Figure 2, which shows a three-dimensional schematic diagram of a material sorting device according to some embodiments of the present disclosure, a portion of the frame is indicated by dotted lines to illustrate the structure of the device. In this embodiment, the frame 10 can be configured to have two side panels 12 opposite to each other in the transverse direction, and a bottom plate 14 fixedly connected to the two side panels 12, and a push-out assembly mounting member 13 is also fixedly mounted on the bottom plate 14. Among them, a spray assembly mounting member 25 is provided on both lateral sides of the spray assembly 20, and the two spray assembly mounting members 25 protrude from both sides of the spray assembly 20 in the transverse direction, and the spray assembly mounting member 25 is provided with a through hole in which bolts can be set in the transverse direction. Bolt holes 121 corresponding to the through holes of the spray assembly mounting member 25 are formed on the opposite sides of the upper part of the two side panels 12, and the spray assembly mounting member 25 is fixedly mounted on the side panels 12 by means of bolts that cooperate with the bolt holes, thereby fixing the spray assembly 20 to the frame 10. This arrangement allows the threaded connection of the blowing assembly 20 to avoid the main working area of ​​the device, preventing material debris and dust from accumulating at the connection, and facilitating the overall disassembly and maintenance of the blowing assembly 20. The ejection assembly mounting member 13 is configured as a roughly rectangular frame, wherein an ejection assembly mounting plate 131 for mounting the ejection assembly 30 is provided on its upper side. The bottom of the ejection assembly 30 is provided with a mounting outer edge 333 protruding along the longitudinal front and rear sides. The mounting outer edge 333 is provided with a vertical through-hole, which is preferably formed as a countersunk hole 3331 in this embodiment. The ejection assembly mounting plate 131 is provided with through-holes corresponding one-to-one to the countersunk holes 3331 of the mounting outer edge 333, and a plurality of loading and unloading slots 132 are formed on the side of the ejection assembly mounting plate 131 facing away from the ejection assembly 30. The plurality of loading and unloading slots 132 are open longitudinally toward the front and rear sides, respectively, and are connected to the through-holes of the ejection assembly mounting plate 131. With this arrangement, bolts inserted into counterbores 3331 on mounting rim 333 can pass through counterbores 3331 and into the through-holes of ejection assembly mounting plate 131, emerging through mounting slots 132. Nuts can then be used to tighten the bolts within mounting slots 132, securing ejection assembly 30 to ejection assembly mounting member 13. This arrangement prevents dust or debris from vertically entering the threaded connection during operation, potentially causing installation difficulties or even blockage.

[0049] FIG3 shows a perspective schematic diagram of a blowing assembly of a material sorting device according to some embodiments of the present disclosure. The blowing assembly 20 may include a nozzle guard 22, which is generally formed as a flat, elongated hollow prism, the interior of which is used to accommodate a pneumatic actuator for blowing. Referring also to FIG1 , in this embodiment, the pneumatic actuator includes a plurality of nozzles 211, each of which is connected to a valve plate assembly 60 disposed at the bottom of the material sorting device via an air pipe 65. The vertical upper side of the nozzle guard 22 is provided with an inclined surface 221 facing the material ejection path a. The inclined surface 221 is provided with a plurality of blowing holes 222 corresponding to the nozzles 211, so that the airflow blown out of the nozzles 211 is directed directly toward the material ejection path a. Furthermore, by providing an inclined surface 221 on the side close to the material ejection path a, it is possible to avoid the material ejection path a, thereby preventing interference with the material and making rational use of space. Ear plates 24 are also provided on both lateral sides of the spray assembly 20, and each ear plate 24 is fixedly connected to the nozzle guard 22. A lifting ring 29 for lifting the spray assembly 20 is also fixed on the ear plate 24. In addition, a vertical through-hole is also provided on the ear plate 24, and the spray assembly mounting member 25 also includes a mounting support plate 251 that protrudes laterally toward the inner side of the device. The mounting support plate 251 is provided with threaded holes corresponding to the through-holes on the ear plate 24, so that the ear plate 24 can be fixed to the mounting support plate 251 in the vertical direction by threaded connection. Also refer to Figure 4, which shows a three-dimensional schematic diagram of the adjustment gasket group of the material sorting device of some embodiments of the present disclosure. The adjustment gasket group 26 includes a plurality of U-shaped gaskets of different thicknesses. The adjustment gasket group 26 is provided between the mounting support plate 251 and the ear plate 24 where the mounting bolts pass, and the groove in the middle of the U-shaped shape is used to accommodate the stud of the mounting bolt. The adjustment gasket group 26 can, for example, include a first gasket 261 with a thickness of 2 mm, a second gasket 262 with a thickness of 3 mm, and a third gasket 263 with a thickness of 5 mm, so that the adjustment gasket group 26 can form different adjustment heights through different combinations. The height of the jet part 21 of the blowing assembly 20 relative to the frame 10 can be flexibly adjusted according to actual needs, and it is very convenient to replace without the need to disassemble the blowing assembly 20. A leak-proof plate 23 is also fixedly provided on the front end surface of the nozzle guard 22. The material of the leak-proof plate 23 can be a flexible material such as rubber. It is fixed to the lower side of the front end surface of the nozzle guard 22 by bolts, and its lower end in the vertical direction is close to the ejection assembly 30, thereby preventing material debris and dust from falling into the gap between the two.

[0050] In some embodiments, the material sorting device further includes a valve plate assembly 60. See FIG5 and FIG1 . FIG5 shows a perspective schematic diagram of the valve plate assembly 60 of the material sorting device according to some embodiments of the present disclosure. The valve plate assembly 60 can be positioned downstream of the ejection assembly 30 along the material ejection path a, and the bottom of the valve plate assembly 60 is bolted to the mounting base of the ejection assembly mounting member. The valve plate assembly 60 includes a valve plate box 61 and a valve plate unit 63 housed within the valve plate box 61. The valve plate box 61 includes a horizontally disposed, upwardly open, elongated box body 611, and a cover plate 612 fastened to the vertical upper side of the box body 611. In this embodiment, multiple cover plates 612 are arranged to be fastened to the upper side of the box body 611 in multiple sections along the horizontal direction. Each cover plate 612 is provided with a handle 621 for operation. This allows each cover plate 612 to be manually lifted by a single operator, facilitating installation and maintenance. Furthermore, because the cover plate 612 is divided into multiple sections, the weight of a single piece is reduced, and thus the thickness of a single cover plate 612 can be appropriately increased, creating conditions for improving the protective capability of the cover plate 612 .

[0051] To ensure safe operation, the portion of each cover plate 612 near the material ejection path a can be configured as a slope 622 parallel to the direction of material movement at the portion corresponding to the material ejection path a. That is, when the material moves along the material ejection path a and is closest to the cover plate 612, its movement direction is parallel to the slope 622. This configuration minimizes the risk of large pieces of material colliding with the cover plate 612 and causing accidental damage. Even if a collision occurs, the angle of the slope 622 can mitigate the impact of the material, preventing damage to components within the valve plate unit 63 due to vibration and impact. In this embodiment, the valve plate assembly 60 also includes a tilted base 66, which tilts the valve plate box 61 as a whole toward the material throwing path a. Preferably, the base 66 makes the upper surface of the valve plate box 61 form an angle of 20° with the horizontal plane. On the one hand, this reduces the impact of the upper surface of the valve plate box 61 when it is accidentally hit by the material. On the other hand, the valve plate unit 63 is also tilted toward the front of the device, making it convenient for the device maintenance personnel to open the cover 612 to maintain the valve plate unit or replace the solenoid valve 631. At the same time, it also makes the air pipe joint 67 of the valve plate unit 63 arranged at the rear of the valve plate box 61 tilt upward, which is convenient for piping operation and maintenance. The valve plate box 61 is also provided with multiple cable outlets 64 on both lateral sides. The power cable and control cable can be electrically connected to the valve plate unit 63 through the cable outlet 64. In this embodiment, a cable sheath is also provided on the cable outlet 64 to prevent the cable from rubbing against the outlet side wall and to prevent debris from entering the interior of the valve plate box 61.

[0052] Referring to Figures 6 and 8 , Figure 6 shows a perspective schematic diagram of a cable guard for a material sorting device according to some embodiments of the present disclosure, while Figure 8 shows an exploded schematic diagram of the material sorting device according to some embodiments of the present disclosure, with a portion of the frame 10 omitted. Two cable guards 16 are symmetrically positioned on either side of the valve plate assembly 60 and are fixedly connected to the ejector assembly mounting member 13 of the frame 10. The cable guards 16 are hollow, with their vertical upper surfaces inclined toward the direction of falling material to mitigate the impact of accidental collisions. The cable guards 16 are open toward one side of the valve plate assembly 60 and positioned adjacent to the lateral side of the valve plate housing 61, shielding and protecting cables extending from the cable outlet 64 on the side of the valve plate housing 61. A mounting side plate 161 with a longitudinal through-hole 152 extending therethrough is provided on the vertical upper side of the cable guards 16. Corresponding threaded holes are provided on the ejector assembly mounting member 13, allowing the cable guards 16 to be bolted to the ejector assembly mounting member 13 along the longitudinal direction. In addition, vertical locating pins 162 are provided on the bottom side of the cable guard 16. The ejection assembly mounting member 13 includes a mounting base 133, which is provided with pin holes 134 corresponding to the locating pins 162. The cable guard 16 can be positioned relative to the mounting base 133 via the locating pins 162. The cooperation between the locating pins and the bolts facilitates the installation and removal of the cable guard 16, thereby reducing the time and difficulty required for installation and maintenance.

[0053] Referring to FIG8 , the material sorting device of this embodiment further includes a front guard assembly 15, which includes a flexible protective pad 151, a multi-section fastening plate, and a protective pad mounting plate 152. The multi-section fastening plate 153 and the protective pad mounting plate 152 clamp the protective pad 151 longitudinally from both sides, and the stacked protective pad mounting plates 152, protective pad 151, and fastening plate 143 are fixed together by bolts. The protective pad mounting plate 152 is also provided with a mounting hole for the longitudinal passage of a bolt, and the ejection assembly mounting member 13 is provided with a threaded hole corresponding to the mounting hole, so that the front guard assembly 15 can be fixed to the ejection assembly mounting member 13 by means of bolts. The protective pad 151 can be made of an elastic material such as rubber. It is roughly rectangular in shape, with its upper vertical end fixed between the protective pad mounting plate 152 and the fastening plate 143. The main body of the protective pad 151 hangs down from the mounting position and is laid on the valve plate assembly 60 and the cable shield 16. Its lateral width exceeds the lateral distribution width of the material transported by the conveying mechanism 210. As a result, the flexible protective pad 151 can effectively protect the valve plate assembly 60 and the cable shield 16, while preventing debris from entering the interior of the device. By lifting the flexible protective pad 151, the valve plate assembly 60 can be easily maintained, saving labor costs. In this embodiment, a rear protective member 17 is also included. The rear protective member 17 is roughly rectangular in shape, with its upper vertical end fixed to the longitudinal rear end face of the spray assembly 20 by bolts. Its main body is arranged vertically downward, thereby covering the rear part of the device and preventing debris from entering the rear part of the device where the air pipe and wire are located and causing contamination.

[0054] As shown in Figures 1 and 7, the outlet of the solenoid valve 631 of the above-mentioned blowing assembly 20 is connected to the nozzle 211, and its inlet is used to receive pressurized gas. As a preferred setting method, the solenoid valve 631 can be arranged in the rear protective member 61 and below the driving member 33, so as to rationally utilize the space and make the overall structure more compact. The blowing assembly 20 controls the pipeline 65 through the solenoid valve 631 to supply air to the nozzle 211 to achieve blowing and sorting. The nozzle 211 needs to be close to the material ejection path a of the material. On the other hand, the push plate 31 of the ejection assembly 30 also needs to be close to the material ejection path a, and the push plate 31 realizes the ejection of the material through the driving member 33. Furthermore, the push plate 31 and nozzle 211 need to be as close as possible to the front section of the material ejection path a. Applying force to achieve sorting during the relatively slow material velocity phase can result in more accurate sorting. If the solenoid valve 631 is positioned immediately below the nozzle 211, the push plate 31 would need to be positioned further downward. The material would then fall to the push plate 31 at a relatively high velocity, making sorting difficult. Furthermore, the path change at the front section of the material ejection path a causes the material to be relatively far away from the recovery area. Therefore, the push plate 31 and nozzle 211 need to be as close as possible to the front section of the material ejection path a, while also ensuring that all components avoid the material ejection path a. Both the driver 33 and the solenoid valve 631 require a certain amount of space, which can easily interfere with other components. The present disclosure employs a rational layout, positioning the solenoid valve 631 below the driver 33 and utilizing the pipeline 63 for air supply. This ensures a drive connection between the driver 33 and the push plate 31 while avoiding the material ejection path a, effectively utilizing the spatial layout. When the solenoid valve is opened, the nozzle 211 can spray the ore passing through it and trigger the ore to change its trajectory, that is, the ore changes its trajectory from originally falling into the first recovery area 231 to a trajectory that allows it to fall into the second recovery area 232. As an example, there are multiple nozzles 211, and the multiple nozzles 211 are evenly spaced along the horizontal direction. The arrangement direction of the nozzles 211 is the same as the arrangement direction of the push plate 31. There are also multiple solenoid valves 631, so that each nozzle 211 can be controlled by a corresponding solenoid valve 631, thereby improving the spraying effect of the spray assembly 20.

[0055] In addition, as shown in Figure 8, a connecting member 101 is further provided in this embodiment, which is used to fix the ejection assembly mounting member 13 and the blowing assembly 20, thereby facilitating transportation. The connecting member 101 includes an upper connecting plate 1011 provided on the upper side, the upper connecting plate 1011 is provided with a vertical through hole, and similarly, the connecting member 101 also includes a lower connecting plate 1012 provided on the lower side, which is also provided with a vertical through hole, and a connecting pillar is formed between the upper connecting plate 1011 and the lower connecting plate 1012. Thus, by connecting the upper connecting plate 1011 to the bottom of the blowing assembly 20 from bottom to top with bolts, and connecting the lower connecting plate 1012 to the upper surface of the ejection assembly mounting plate 131 of the ejection assembly mounting member 13 from top to bottom with bolts, the blowing assembly 20 can be fixed to the ejection assembly mounting member 13. The provision of the connecting member 101 enables the blowing assembly 20, the ejecting assembly 30 and the ejecting assembly mounting member 13 to be transported independently as a whole, thereby saving transportation costs.

[0056] Referring again to Figures 1, 2, and 8, in this embodiment, a blowing assembly 20 is mounted on the upper side of the side panel 12 of the frame 10, and an ejection assembly 30 is mounted on the ejection assembly mounting member 13 at a position downward along the material ejection path a. The side panel 12 for mounting the blowing assembly 20 is defined as a first mounting portion, and the ejection assembly mounting member 13 for mounting the ejection assembly 30 is defined as a second mounting portion. The first mounting portion is vertically higher than the second mounting portion and longitudinally positioned behind the first mounting portion, i.e., the first mounting portion and the second mounting portion are arranged in a stepped manner. This positional relationship creates a horizontal separation and a vertical step between the blowing assembly 20 and the ejection assembly 30, respectively mounted on the first and second mounting portions, on the frame 10. This separates the actual operating portions of the blowing assembly 20 and the ejection assembly 30 in both the vertical and horizontal directions, allowing them to perform material removal operations along the material ejection path a without interfering with each other and allowing them to cooperate with each other. The nozzle 211, the actual action part of the blowing assembly 20, and the push plate 31, the actual action part of the pushing assembly 30, are staggered in the horizontal direction, that is, the nozzle 211 located above is closer to the conveying mechanism 210, and the push plate 31 is farther away from the conveying mechanism 210 in the horizontal direction. At the same time, the nozzle 211 is located above the push plate 31 in the vertical direction, thereby ensuring that both are close to the material throwing path a and can also not interfere with each other. The nozzle 211 or the push plate 31 will not affect the material that needs to be thrown normally on the material throwing path a, and it can also avoid that the materials that change their trajectories through the nozzle 211 and the push plate 31 will not interfere with each other. The blowing assembly 20 and the pushing assembly 30, while realizing two sorting methods to meet the needs of sorting materials with different characteristics, can ensure the reliability and accuracy of sorting through the layout method provided by the present disclosure, and can also make the spatial layout more compact and reasonable.

[0057] With the cooperation of a detection mechanism that can distinguish the size of materials, the blowing assembly 20 and the pushing assembly 30 can be connected to a control module, and the material sorting rules can be set through the control module. For example, because the blowing assembly 20 uses a solenoid valve to control the nozzle 211 to spray air to blow the material to move, its movement speed is fast and the frequency is high, but the driving force is small, which is suitable for removing small-sized materials; while the pushing assembly 30 uses a cylinder to drive the push plate 31 to push the material to be removed. Its movement frequency is relatively low, but the driving force is greater, which is suitable for removing large-sized materials to be removed. Therefore, screening rules can be set and a division of labor mode can be set: use the blowing assembly 20 to remove smaller materials to be removed, and use the pushing assembly 30 to remove larger materials to be removed. In this way, the sorting process can be refined and sorting errors can be reduced. Alternatively, a collaborative mode can also be set: it is stipulated that materials to be rejected below the first size are only removed using the blowing assembly 20, materials to be rejected between the first size and the second size are removed together by the blowing assembly 20 and the pushing assembly 30, and materials to be rejected larger than the third size are only removed by the pushing assembly 30, wherein the first size < the second size < the third size. This rule setting can improve the sorting efficiency while reducing the sorting error. In addition, the above rule setting can also be numerically adjusted according to actual conditions, or more types of detection mechanisms can be added to form more sophisticated screening rules. The present disclosure does not impose any restrictions in this regard. The first mounting portion and the second mounting portion are arranged in a stepped shape, which also creates conditions for the separate disassembly and assembly of the blowing assembly 20 and the pushing assembly 30. During disassembly and assembly, the blowing assembly 20 and the pushing assembly 30 can both be moved out or moved in from the front side of the device, reducing equipment maintenance and installation costs.

[0058] Because the blowing assembly 20 and the ejecting assembly 30 of this embodiment can be installed relatively independently, their positions can be easily adjusted, spatial layout can be rationally utilized, mutual interference can be avoided, and the accuracy and reliability of sorting can be guaranteed. Moreover, any of the components can be easily installed, debugged, repaired, and replaced. On the other hand, depending on the actual situation, either the blowing assembly 20 or the ejecting assembly 30 can be installed and used independently. In some cases, sorting can be performed in a single manner, reducing costs and space usage.

[0059] Referring to Figure 9, a side cross-sectional view of a material sorting device according to some embodiments of the present disclosure, shown with a separate ejector assembly, is shown. Specifically, only the ejector assembly 30 is mounted on the frame 10, while the first mounting portion is fitted with a first protective shield 18 to prevent dust accumulation. In this configuration, the ejector assembly 30 can operate independently. This configuration is suitable for situations where only large-sized materials to be rejected need to be sorted, or when a large number of large-sized materials are to be rejected.

[0060] Referring to Figure 10 , a side cross-sectional view of a material sorting device according to some embodiments of the present disclosure, shown with a separate blow assembly, is shown. Similarly, only the blow assembly 20 is mounted on the frame 10, while a second protective shield 19, designed to prevent dust accumulation, is mounted on the second mounting portion. This configuration, in which the blow assembly 20 alone sorts the material, is suitable for applications requiring only small-sized materials to be rejected, or for situations involving a large number of small-sized materials to be rejected.

[0061] Those skilled in the art will understand that the material sorting device in the above-described embodiment only discloses an arrangement scheme including two mounting parts. However, according to actual conditions, more mounting parts can be provided to form more mounting parts along the material ejection path, thereby providing more execution components for sorting materials, thereby further improving the sorting efficiency of the device. For example, on the basis of the above-mentioned installed blowing assembly and ejection assembly, additional mounting side plates can be provided on both lateral sides below the material ejection path. The additional mounting side plates have a lower height than the ejection assembly mounting parts and are closer to the front side of the device, thereby forming a third mounting part that is arranged in a stepped manner with the first mounting part and the second mounting part. By fixing the additional execution component to the third mounting part, the sorting efficiency can be further improved. In addition, in the above-mentioned embodiment, the side plates arranged on both sides of the device are defined as the first mounting part, and the ejection assembly mounting part fixed to the bottom plate is defined as the second mounting part, but the present disclosure does not impose any restrictions on the specific composition of the mounting part. For example, a stepped frame can be directly set up, so that the blowing assembly and the pushing assembly are installed on different steps of the frame in the vertical direction, or two longer side walls can be set up, on which multiple groups of mounting holes are arranged in a stepped manner, and the blowing assembly and the pushing assembly are respectively installed horizontally on the side walls, etc. It is only necessary to ensure that the corresponding mounting parts have the characteristics of a stepped arrangement.

[0062] According to the material sorting device of the embodiment of the present disclosure, the various operating parts in the device are modularly set, and the rack is laid out in a corresponding modular installation method, so that the blowing component and the pushing component can work independently or cooperate with each other, combining the advantages of the blowing and pushing methods, and achieving the effect of sorting large and small particles at the same time through appropriate control methods. According to the characteristics of the blowing component's large sorting output, high efficiency, and good reliability and the pushing component's large sorting and processing particle size, through reasonable workflow control, the advantages of the two sorting structures are combined, and the mine does not need to screen the materials according to the particle size in advance, thereby achieving mixed flow sorting of large and small particle materials. The labor cost, equipment cost and environmental protection cost caused by material screening are reduced, the material sorting efficiency and output are greatly improved, and greater economic benefits can be created for the mine. The pushing component or the blowing component can also be separately set on the rack according to actual work needs, so that the material sorting device can install different execution components according to the sorting requirements of different sites, thereby saving equipment costs. At the same time, it can flexibly adjust the sorting strategy to cope with different working conditions. When the sorting strategy changes, the corresponding execution components with low working efficiency can be removed to avoid unnecessary loss or pollution of seldom used blowing components or pushing components in the material sorting working environment.

[0063] Figure 12 shows a perspective schematic diagram of a material sorting device according to some embodiments of the present disclosure. The material sorting device 100 is used to sort a target material from multiple materials and includes a fixed frame 32, a driving member 33, and a push plate 31 for use in a material sorting device according to various embodiments of the present disclosure. The fixed frame 32 is hinged to a first hinge portion 3111, while the driving member 33 is hinged to a second hinge portion 3112. As a result, the push plate 31 of the material sorting device can be driven by the telescopic movement of the driving member 33 to swing about the rotation axis of the first hinge portion 3111, thereby pushing the target material for sorting.

[0064] Referring to Figures 13 and 14 , Figure 13 shows a perspective schematic diagram of a push plate for a material sorting device according to some embodiments of the present disclosure, and Figure 14 shows an exploded schematic diagram of a push plate for a material sorting device according to some embodiments of the present disclosure. The push plate serves as an actuator in the material sorting device, directly contacting and pushing materials to be sorted and removed for separation. The push plate in this embodiment includes a main plate 311 and a sub-plate 312 superimposed on the front of the main plate 311. A first hinge 3111 is provided at one end of the main plate 311, and a second hinge 3112 is provided on the back of the main plate. The first hinge 3111 is hingedly connected to a fixed frame 32, which can be a fixed frame 32 of a push assembly fixed to the frame of the material sorting device. The second hinge 3112 is hingedly connected to a driver that drives the push plate to swing about the rotation axis of the first hinge 3111. The driver 33 can be a cylinder, linear motor, or other actuator.

[0065] In this embodiment, the side of the mainboard 311 facing the material to be rejected is generally defined as the front side, and the side facing away from the material to be rejected is generally defined as the back side. Furthermore, as shown in Figure 13 , the direction along the mainboard 311 parallel to the rotation axis of the first hinge 3111 is defined as the transverse direction, and the direction perpendicular to the rotation axis of the first hinge 3111 is defined as the longitudinal direction. The positions of other components are similarly described with reference to the definitions of the various directions of the mainboard 311.

[0066] As shown in Figure 14, the main board 311 can include a generally rectangular main body 3110, i.e., a long board section. A short board section 3113 extending at an angle from the main body 3110 is provided at the first longitudinal end of the main body 3110. A first hinge portion 3111 is formed at the end of the short board section 3113 facing away from the main board 3110. The first hinge portion 3111 comprises a generally cylindrical main body 3110, which includes a rotation axis hole 31111 extending transversely therethrough. The rotation axis hole 31111 is used to accommodate components such as a rotation axis and bearings, enabling the main board 3111 to swing about the rotation axis, thereby being hingedly connected to the fixed frame of the material sorting device. The back of the main board 311 is also provided with two generally triangular connecting side panels 313. These two connecting side panels 313 are arranged side by side at the transverse center of the back of the main board 311 and are fixedly connected to the main board 3110. A second hinge portion 3112 is formed at the distal end of the connecting side plate 313, facing away from the main main body 3110. The second hinge portion 3112 includes a hinge axis hole extending transversely through the connecting side plate 313. The hinge axis hole is used to accommodate a hinge axis for hinge connection with the drive member. The secondary plate 312 can be generally rectangular and is superimposed on the front of the main main plate 311 and fixedly connected to the main main plate 311.

[0067] Referring simultaneously to Figures 15 and 16 , Figure 15 illustrates a schematic transverse cross-sectional view of a push plate for a material sorting device according to some embodiments of the present disclosure, and Figure 16 illustrates a schematic longitudinal cross-sectional view of a push plate for a material sorting device according to some embodiments of the present disclosure. A first positioning portion is formed on the front surface of the main plate 311, which serves to position the sub-plate 312. In this embodiment, the first positioning portion is formed as a trapezoidal boss 3116 protruding from the surface of the main plate 311. The boss 3116 forms a protrusion that is narrow at the bottom and wide at the top on the front side of the longitudinal cross-section of the main plate 311. The boss 3116 extends perpendicular to the rotation axis of the first hinge portion 3111. A mating positioning portion that mates with the first positioning portion may be formed on the sub-plate 312. In this embodiment, the mating positioning portion is a trapezoidal positioning groove 3121 that forms a positive fit with the boss 3116. The trapezoidal positioning groove 3121 is located in the transverse center of the sub-plate 312 and extends longitudinally along at least one side of the sub-plate 312, enabling the sub-plate 312 to be mounted longitudinally to the main plate 311 on the front face of the main plate 311. The trapezoidal boss 3116 then longitudinally engages within the trapezoidal positioning groove 3121, securing the sub-plate 312 in a direction perpendicular to the front face of the main plate 311. In this embodiment, the trapezoidal boss 3116 is located on a side of the main plate body 311 adjacent to the first hinge portion 3111. This facilitates pre-positioning of the sub-plate 312 on the front face of the main plate 311 during installation, based on the engagement between the trapezoidal positioning groove 3121 and the trapezoidal boss 3116. The trapezoidal boss 3116 has a certain length along its extension direction, which in this embodiment is set to be relatively short. This arrangement reduces the contact area between the trapezoidal positioning groove 3121 and the trapezoidal boss 3116 when the secondary plate 312 is mounted on the primary plate 311, thereby reducing friction and facilitating installation. Those skilled in the art will appreciate that the trapezoidal boss 3116 can be formed to have a longer extension length, which can provide more precise guidance and positioning for the secondary plate 312.

[0068] In this embodiment, a second positioning portion is further provided on the front side of the main board 311, at the second end away from the first hinge 3111. This second positioning portion is used to further position the sub-board 312. Specifically, a positioning platform 3114 is formed on the second end of the main board 311, protruding perpendicularly from the front side of the main board 311. This positioning platform 3114 includes a vertical end surface 31141 facing the first hinge 3111. The second positioning portion may include a positioning groove 3115 that extends from the vertical end surface 31141 into the positioning platform 3114, away from the first hinge 3111. This positioning groove 3115 is configured to mate with a positioning tongue 3122 formed on the end of the sub-board 312 to position the sub-board 312 perpendicularly to the front side of the main board 311. When the positioning groove 3115 receives the pressing block 34, the sub-board 312 is more firmly fixed to the main board 311, preventing it from rocking left or right relative to the main board 311. The positioning tongue 3122 can be a rectangular protrusion extending longitudinally from the end surface 3124 of the sub-plate 312, and the end surface 3124 is adapted to mate with the vertical end surface 31141 of the positioning platform 3114 after the positioning tongue 3122 is inserted into the positioning groove 3115 of the positioning platform 3114. The shape of the end surface 3124 can match the shape of the vertical end surface 31141 of the positioning platform 3114, so that there is no height difference at the connection between the two, preventing the accumulation of debris or scratches during the sorting process. In this embodiment, the first positioning portion is disposed on the first longitudinal side of the front face of the main plate 311, while the second positioning portion is disposed on the second longitudinal side of the front face of the main plate 311. This allows the sub-plate 312 to be constrained on both longitudinal sides of the main plate 311 by the two positioning portions, preventing fatigue or deformation of the connection portion due to uneven fixing force during operation. Those skilled in the art will appreciate that, in this embodiment, the second positioning portion is configured to include a longitudinal positioning groove 3115 provided on a positioning platform 3114 protruding from the end of the sub-plate 312. However, the present disclosure does not limit the formation method of the second positioning portion. For example, the positioning platform can be provided in the middle section of the sub-plate 312, or the second positioning portion can be configured as a longitudinally extending positioning protrusion, while corresponding longitudinal positioning grooves can be formed on the end surface of the sub-plate.

[0069] Referring to Figures 17 and 18 , Figure 17 shows a perspective schematic diagram of a push plate for a material sorting device according to some embodiments of the present disclosure, and Figure 18 shows an exploded schematic diagram of a push plate for a material sorting device according to some embodiments of the present disclosure. In this embodiment, similar to the previous embodiments, the push plate for a material sorting device includes a main plate 311 and a sub-plate 312 superimposed on the front of the main plate 311. The main plate 311 is similarly provided with a short plate section 3113 and a first hinge portion 3111 at its first longitudinal end. The difference is that the first positioning feature on the main plate 311 is configured as a T-shaped boss 3116 extending parallel to the rotation axis of the first hinge portion 3111 on the front of the main plate 311. The mating positioning feature on the sub-plate 312 in this embodiment is configured as a T-shaped positioning slot 3121 corresponding to the T-shaped boss 3116. The T-shaped positioning slot 3121 extends transversely through the sub-plate 312, enabling the sub-plate 312 to be mounted to the main plate 311 in a transverse, form-fitting manner, along the front of the main plate 311. A positioning sidewall 3117 is also provided at the end of one lateral side of the front face of the main plate 311. This positioning sidewall 3117 is used to abut the lateral side of the sub-plate 312. In this embodiment, the T-shaped boss 3116 extends laterally from one lateral end of the main plate 311 and is integrally formed with the positioning sidewall 3117. This allows the positioning sidewall 3117 to partially function as a reinforcing rib, further providing structural strength to the positioning sidewall 3117. Those skilled in the art will appreciate that the present disclosure does not limit the shape of the first positioning portion; for example, the T-shaped boss 3116 may extend to the lateral middle of the main plate 311 and terminate there. At the same time, in this embodiment, a positioning support 3114 is also provided at the second longitudinal end of the main plate 311. This positioning support 3114 protrudes vertically from the front face of the main plate 311 and has a support end surface 31141 facing the first hinge portion 3111. This support end surface 31141 is used to abut against the longitudinal end surface of the sub-plate 312 to provide further positioning. Furthermore, this positioning support 3114 provides longitudinal support for the sub-plate 312 when it is impacted by material, thereby preventing damage to the T-shaped boss 3116 and enhancing the stability of the sub-plate 312 after installation.

[0070] In some embodiments, the push plate 31 may further include: a pressing block 34 disposed on the front surface of the main board 311. A pressing block 34 for longitudinally fixing the auxiliary board 312 is also disposed on the front surface of the main board 311. On one side of the front surface of the short board section 3113 of the main board 311, a threaded hole 31131 for fixing the pressing block 34 is provided, and a pressing block limiting groove 3123 for limiting the pressing block 34 is provided at one end of the auxiliary board 312 adjacent to the short board section 3113 longitudinally. The push plate 31 may further include: a bolt passing through the pressing block 34 and screwed into the main board 311. As shown in FIGS. 13, 13, and 14, the bolt is configured to fix the pressing block 311 to the push plate 31 body and press the auxiliary board 312 between the pressing block 34 and the first positioning portion. The pressing block 34 is generally in the shape of a rectangular sheet, and through holes for fixing are formed thereon so that it can be fixed to the short board section 3113 of the main board 311 by bolts, and spring washers are added to enhance stability. One side of the pressing block 34 facing the main board 311 longitudinally abuts against the longitudinal end of the auxiliary board 312, and at least a part of it is received in the pressing block limiting groove 3123 of the auxiliary board 312. The two lateral sides of the pressing block 34 are respectively limited by the inner walls on both sides of the pressing block limiting groove 3123 to further prevent relative movement between the pressing block 34 and the auxiliary board 312. As a preferred example, the push plate 31 further includes a boss 3116 fixedly provided on the main board 311 and abutting against one end of the auxiliary board 312, a pressing block 34 provided on the main board 311 and abutting against the other end of the auxiliary board 312, and a bolt passing through the pressing block 34 and screwed into the main board 311. Among them, the bolt is configured to fix the pressing block 34 to the main board 311 and urge the auxiliary board 312 to be pressed between the pressing block 34 and the boss 3116. In this way, it can be ensured that the surface of the auxiliary board 312 facing away from the main board 311 is available for the impact of ore, and it is ensured that the utilization rate of this surface can be close to 100%. The main board 311 may be in the shape of a "乁" character. As shown in FIG. 14, it includes a short board section 3113 and a long board section (main body 3110) connected to each other. The above-mentioned boss 3116 may be fixedly provided on the front surface of the main board 311 and located at a part of the long board section far from the short board section 3113, and the pressing block 34 may be provided on the front surface of the main board 311 and located at a part of the short board section 3113 close to the long board section. Thus, when the bolt passes through the pressing block 34 and is screwed into the short board section 3113 of the main board 311, the bolt can apply a greater and more direct pressure to the auxiliary board 312 through the pressing block 34, ensuring that the auxiliary board 312 can be more firmly fixed between the pressing block 34 and the boss 3116.

[0071] In this embodiment, a connector 314 is also provided for securely connecting the main plate 311 and the sub-plate 312. This connector 314 is located at the end of the main plate 311 facing away from the positioning sidewall 3117 in the transverse direction. It comprises a rectangular plate body and at least two connection holes defined therein. The main plate 311 and the sub-plate 312 each have transversely extending threaded holes formed on their corresponding transverse sides, allowing the connector 314 to be securely connected to the main plate 311 and the sub-plate 312, respectively, via bolts. Furthermore, limiting grooves are formed on the sides of the main plate 311 and the sub-plate 312 corresponding to the connector 314. The groove on the main plate 311 is defined as a first limiting portion 47, while the groove on the sub-plate 312 is defined as a second limiting portion 3125. The first limiting portion 47 and the second limiting portion 3125 together form a form-fitting arrangement to accommodate the connector 314, preventing displacement of the connector 314 relative to the main plate 311 or the sub-plate 312. The second limiting portion 3125 on the sub-plate 312 is formed as a rectangular groove on a lateral sidewall of the sub-plate 312. This rectangular groove opens transversely toward the connector 314 and perpendicularly toward the main plate 311. On its side facing away from the main plate 311, a vertical limiting wall 31251 is formed. This vertical limiting wall 31251 is used to abut against the side of the connector 314 perpendicularly to the front of the main plate 311, thereby limiting the position of the connector 314. Through this arrangement, the limiting groove formed by the first limiting portion 47 and the second limiting portion 3125 can form a positive fit to limit the connector 314 in three circumferential directions. This eliminates the need for excessive bolt connections between the connector 314 and the main plate 311 and the sub-plate 312 to restrict its freedom of movement. For example, in this embodiment, the connector 314 only needs to be provided with two connection holes: one for connection to the main plate 311 and the other for connection to the sub-plate 312. This reduces the processing costs of the main plate 311 and the auxiliary plate 312, and due to the reduced number of threaded holes, the strength of the main plate 311 and the auxiliary plate 312 is increased. Furthermore, the threaded holes can be staggered both horizontally and vertically, providing greater installation space, allowing for the use of larger bolts. Furthermore, anti-loosening components such as spring washers can be added to further enhance stability. This also results in a smaller connector 314, making the layout more compact.

[0072] Those skilled in the art will appreciate that while the above embodiments describe only one example of a first positioning portion formed on the main board and a corresponding mating positioning portion formed on the secondary board, the present disclosure is not limited in this respect. For example, multiple parallel first positioning portions may be provided to enhance the stability of the connection. Alternatively, in the embodiments shown in Figures 17 and 18 , a laterally extending additional positioning portion may be formed on the end surface 31141 of the positioning support 3114, and a positioning protrusion may be formed on the longitudinal end of the secondary board 312 to mate with the additional positioning portion, thereby further enhancing the stability of the connection. Furthermore, while the above embodiments describe a solution in which one of the first positioning portion and the mating positioning portion is formed with a T-shaped or trapezoidal cross-section, as an alternative, one of the first positioning portion and the mating positioning portion may be formed as a protrusion having, for example, an L-shaped cross-section, while the other may be formed with a groove mateable with the protrusion. This requires only that a stopper be formed between the two portions in a direction perpendicular to the front face of the main board.

[0073] According to the push plate for the material sorting device of multiple embodiments of the present disclosure, the stability of the connection between the sub-plate and the main board is enhanced by setting the sub-plate to be limited in a direction perpendicular to the front face of the main board. The sub-plate is a replaceable wear-resistant plate and is a component that is directly subjected to the impact of the material. When the sub-plate 312 is severely worn or damaged, it is only necessary to replace the sub-plate 312, and since the disassembly and assembly of the sub-plate 312 is simpler and lighter, the push plate 31 used in this embodiment has the advantages of saving time and effort and low maintenance cost. Preferably, the material of the sub-plate 312 is mainly selected from manganese steel or chromium steel (such as 40CrMo or 42CrMo). Since manganese steel or chromium steel has high mechanical strength and good wear resistance, it can effectively improve the service life of the sub-plate 312 and further reduce the maintenance cost of the material sorting device 100, especially the sub-plate 312. Because the main and auxiliary plates are mutually restrained by a form-fitting mechanism, all six degrees of freedom of the auxiliary plate are restricted. This means that even if the auxiliary plate is subjected to a large amount of material and sustained impact for a long period of time, the impact force will not cause the restraints between the main and auxiliary plates to fail, leading to bolt breakage. Therefore, it is particularly suitable for demanding working environments such as material sorting.

[0074] As shown in FIG. 1 to FIG. 4 and FIG. 19 - FIG. 21 , the material sorting device 100 may include: a fixing frame 32 , a plurality of push plates 31 , a pressing plate 40 and a reinforcement assembly 50 .

[0075] The fixing frame 32 includes a support portion and a mounting portion extending from above the support portion. A first arc-shaped groove is provided on one side of the mounting portion along the width direction of the fixing frame 32. The material sorting device 100 may also include a base. The fixing frame 32 may be arranged upright on the base, and the bottom of the fixing frame 32 is fixedly connected to the base. The top of the fixing frame 32 can be used to mount multiple push plates 31. The length of the push plates 31 can extend along the direction in which the material sorting machine 200 conveys materials, and the width of the push plates 31 can be along the width direction of the conveying mechanism 210 of the material sorting machine 200. The width direction of the fixing frame 32 can be parallel to the base and extend along the width direction of the push plates 31. The lower portion of the fixing frame 32 can be a support portion and can have multiple bolt holes for mounting and supporting components such as the pressure plate 40. The upper portion of the fixing frame 32 can be a mounting portion. A first arc-shaped groove can be provided on one side of the mounting portion along the width direction of the fixing frame 32. The first arc-shaped groove can be used to mount the push plates 31. For ease of description, the mounting frame 32 is divided into two regions: a support portion and a mounting portion. In some examples, the mounting portion and the support portion can be a single, integrally formed component. In some examples, as shown in Figures 19 and 20, the mounting frame 32 can have a certain bend, with the bend located below the support portion, giving the mounting frame 32 a 7-shaped longitudinal cross-section, facilitating the installation of components such as the push plate 31. The support portion and mounting portion of the mounting frame 32 can also extend vertically, perpendicular to the base.

[0076] Multiple push plates 31 are arranged side by side along the width of the fixed frame 32. One end of each push plate 31 is provided with a rotation axis, which is mounted within the first arcuate groove. Each push plate 31 may have a rotation axis of the same diameter. The rotation axes of the multiple push plates 31 may be collinear and mounted within the first arcuate groove. Each push plate 31 can rotate about its rotation axis, thereby lifting and changing the trajectory of the material being removed. One side of the push plate 31 is used to strike the material being removed. The other side may be directly or indirectly connected to a drive mechanism, such as a pneumatic cylinder. When the push plates 31 are in operation, the cylinder's piston rod extends outward, directly or indirectly pushing the push plates 31. This applies an upward force to the end of the push plates 31 away from the rotation axis, causing them to tilt about the rotation axis to their operating position. The cylinder's piston rod simultaneously supports the push plates 31 in the operating position, allowing them to strike the material being removed. When the push plates 31 are not in operation, the cylinder's piston rod retracts into the cylinder, lowering the push plates 31 about their rotation axis.

[0077] The front of the pressure plate 40 is connected to the fixing frame 32. The lower part is a flat plate and the upper part is an arcuate part. The flat plate is fixedly connected to the support part of the fixing frame 32 by a plurality of fastening screws 41. The arcuate part is formed with a second arcuate groove, which docks with the first arcuate groove to form a circular hole along the width direction of the fixing frame 32 for mounting the rotating shaft. The side of the pressure plate 40 facing the fixing frame 32 is the front side, and the side of the pressure plate 40 facing away from the fixing frame 32 is the back side. The lower part of the pressure plate 40, i.e., the flat plate, is flat. The front side can be fixedly connected to the support part of the fixing frame 32 by a plurality of fastening screws 41. The fastening screws 41 can be distributed along the width direction of the fixing frame 32. The upper portion of the pressure plate 40 can be an arc-shaped portion, the back surface can be an outwardly convex arc, and the front surface can be formed with a second arc-shaped groove. The cross-section of the second arc-shaped groove can be a semicircular groove with the same diameter as the first arc-shaped groove, which can be connected with the first arc-shaped groove to form a circular hole along the width direction of the fixed frame 32. The rotation axes of multiple push plates 31 can be respectively installed in the circular holes, allowing the push plates 31 to rotate freely around the rotation axes, thereby lifting and changing the movement trajectory of the material to be removed. As shown in Figures 19 and 20, the arc-shaped portion forms flat surfaces on both radial sides of the second arc-shaped groove facing the mounting portion of the fixed frame 32. The mounting portion of the fixed frame 32 also forms flat surfaces on both radial sides of the first arc-shaped groove facing the arc-shaped portion of the pressure plate 40. When the pressure plate 40 is mounted to the fixed frame 32 by tightening screws 41, the above two flat surfaces can be connected, and the first arc-shaped groove and the second arc-shaped groove form a circular hole for mounting the rotation axis of the push plate 31.

[0078] The reinforcement assembly 50 is fixedly connected to the fixing frame 32 from the back of the pressure plate 40, and is used to reinforce the connection between the pressure plate 40 and the fixing frame 32. During the operation of the push plate 31, it is necessary to hit the falling materials. The push plate 31 is subjected to a large impact force by the impact of the materials. The impact force is transmitted to the pressure plate 40 through the rotating shaft, thereby applying a force to the pressure plate 40 in a direction away from the fixing frame 32, causing the fixing screws to loosen, fall off or break due to excessive force. The reinforcement assembly 50 of the embodiment of the present disclosure can apply a pressing force to the pressure plate 40 toward the fixing frame 32, thereby resisting the force applied by the push plate 31 to the pressure plate 40 in a direction away from the fixing frame 32, effectively preventing the fixing screws from loosening, making the connection between the pressure plate 40 and the fixing frame 32 more stable, and ensuring the stability of the installation of the pressure plate 40 and the push plate 31. The reinforcement component 50 can be fixedly connected to the fixing frame 32 from the back of the pressure plate 40, and can pass through the pressure plate 40 or be fixed to the fixing frame 32 at other positions. On the other hand, it can apply a clamping force toward the fixing frame 32 to the pressure plate 40 from the back of the pressure plate 40 to achieve a tightening effect on the connection between the pressure plate 40 and the fixing frame 32, thereby ensuring the stability of the push plate 31 and preventing the pressure plate 40 and the push plate 31 from falling off.

[0079] The material sorting device 100 provided by the present disclosure installs the push plate 31 on the fixing frame 32 via the pressure plate 40, and fixes the pressure plate 40 to the fixing frame 32 via the fastening screws 41 to prevent the push plate 31 from falling. By providing a reinforcement component 50, a pressing force is applied to the pressure plate 40 from the back side toward the fixing frame 32. Therefore, when the push plate 31 is subjected to a large impact force, the force applied by the push plate 31 to the pressure plate 40 in the direction away from the fixing frame 32 is resisted, effectively preventing the fastening screws 41 from loosening, falling off, and breaking, thereby extending the service life of the fastening screws 41 and effectively improving the stability of the installation of the pressure plate 40 and the push plate 31.

[0080] In some embodiments, as shown in Figures 19 and 20, the mounting portion of the fixing frame 32 can be provided with a first bolt hole. The reinforcement assembly 50 includes a first bolt 51 that passes through the back of the curved portion and connects to the first bolt hole, securing the curved portion to the mounting portion. In the disclosed embodiment, the first bolt 51 secures the curved portion of the upper portion of the pressure plate 40 to the mounting portion of the upper portion of the fixing frame 32, thereby providing a more secure connection between the pressure plate 40 and the fixing frame 32. Furthermore, the curved portion of the upper portion of the pressure plate 40 is closer to the rotation axis of the push plate 31. This securement of the curved portion to the fixing frame 32 can better prevent outward vibration or displacement of the pressure plate 40 in the event of an impact on the push plate 31, thereby reducing the risk of the fastening screw 41 falling off. In some embodiments, the pressure plate 40 can be provided with a first through-hole, which can be provided in the curved portion. The first bolt 51 can pass through the first through-hole from the back of the curved portion and connect to the first bolt hole, thereby securing the curved portion to the mounting portion. The first bolt holes can be distributed along the width direction on the mounting portion of the fixing frame 32 and located at the planes on both sides of the radial direction of the first arc-shaped groove. The first through holes can be distributed along the width direction on the arc-shaped portion of the pressure plate 40 and located at the planes on both sides of the radial direction of the second arc-shaped groove. When the first bolt 51 passes through the back of the arc-shaped portion and is installed in the first bolt hole, the first bolt 51 avoids the circular hole for installing the rotating shaft of the push plate 31, preventing the first bolt 51 from interfering with the rotating shaft of the push plate 31, ensuring that the rotating shaft of the push plate 31 can be installed in the circular hole, and allowing the push plate 31 to rotate freely around the rotating shaft. When the push plate 31 hits the material to be removed during operation, vibration is easily generated, causing the fixing screws to loosen due to vibration. By providing the first bolt 51, the pressure plate 40 is reinforced at the arc-shaped portion, which can reduce the vibration of the fixing screws and prevent the screws from loosening. Since a circular hole is formed at the joint between the arc-shaped portion of the pressure plate 40 and the mounting portion of the fixing frame 32, which is used to install the rotating shaft of the push plate 31, the arc-shaped portion and the mounting portion are fixedly connected by the first bolt 51, so that the pressure plate 40 is subjected to a clamping force toward the fixing frame 32 at the arc-shaped portion, which can effectively improve the connection stability between the pressure plate 40 and the fixing frame 32, prevent the fixing screws from loosening, falling off and breaking, ensure the stability of the installation of the push plate 31, and improve the service life of the fixing screws.

[0081] In some embodiments, as shown in FIG19 , the first bolt hole can be located on a side of the first arcuate groove away from the support portion and adjacent to the first arcuate groove. The first bolt 51 can pass through the arcuate portion of the pressure plate 40 from a side of the second arcuate groove away from the flat portion and adjacent to the second arcuate groove. In some embodiments, the first through-hole provided in the arcuate portion of the pressure plate 40 for the first bolt 51 to pass through can be located on a side of the second arcuate groove away from the flat portion and adjacent to the second arcuate groove. When the first bolt 51 passes through the first through-hole and is installed in the first bolt hole, the first bolt 51 is located adjacent to the rotation axis of the push plate 31. When the push plate 31 is in working condition, the material to be removed hits the push plate 31, and the rotation axis of the push plate 31 is the main force point. Therefore, when the push plate 31 is in working condition, the rotation axis will apply a force to the pressure plate 40 in the direction away from the fixing frame 32 at the second arc-shaped groove. The first bolt hole is located on the side of the first arc-shaped groove away from the support portion and is arranged close to the first arc-shaped groove. The first bolt 51 can be located close to the rotation axis to apply a clamping force to the pressure plate 40 in the direction of the fixing frame 32, thereby making the installation of the pressure plate 40 and the fixing frame 32 more stable and effectively preventing the fixing screws from loosening and breaking.

[0082] In some embodiments, as shown in Figures 19 and 20, the flat plate portion may be provided with a plurality of screw holes for installing fastening screws 41; the number of screw holes is at least four, and / or the outer diameter of the thread of the fastening screw 41 is greater than or equal to 12 mm. This can improve the strength and stability of the screw connection, thereby improving the strength and stability of the connection between the pressure plate 40 and the fixing frame 32. Providing a fastening screw 41 with an outer diameter of the thread greater than or equal to 12 mm effectively improves the tensile strength of the fastening screw 41, thereby preventing the screw from breaking due to excessive stress. This can effectively improve the tensile strength of the fastening screw 41 and improve the stability of the installation of the fastening screw 41, thereby improving the strength and stability of the connection between the pressure plate 40 and the fixing frame 32 and improving the safety of the push plate 31 mechanism.

[0083] In some embodiments, as shown in Figures 19 and 20, the reinforcement assembly 50 may include: an anti-slip plate 52, which is arranged on the back of the flat plate portion. The anti-slip plate 52 is fixedly connected to the support portion of the fixing frame 32 by a second bolt, pressing the pressure plate 40 against the fixing frame 32. There may be one or more anti-slip plates 52, each of which may extend along the width direction of the fixing frame 32, be arranged on the back of the flat plate portion and fixedly connected to the support portion; multiple anti-slip plates 52 may be distributed along the width direction of the fixing frame 32, and be respectively arranged at different positions on the back of the flat plate portion, and each anti-slip plate 52 may be respectively fixedly connected to the support portion. The anti-slip plate 52 may be arranged on the back of the flat plate portion, and the anti-slip plate 52 may partially abut against the flat plate portion, while the remaining portion abuts against the support portion of the fixing frame 32, and the second bolt is passed through the anti-slip plate 52 from the back of the anti-slip plate 52 and fixedly connected to the fixing frame 32. The anti-slip plate 52 can also abut against the flat plate portion, as shown in Figures 19 and 20. The flat plate portion can be provided with a second through hole, and the second bolt can also pass through the second through hole from the back of the anti-slip plate 52 and be fixed to the support portion of the fixing frame 32. The anti-slip plate 52 is provided on the back of the flat plate portion, pressing the pressure plate 40 as a whole from the back of the flat plate portion and covering the fastening screws 41, which can effectively prevent the fastening screws 41 from falling off due to vibration. By providing the anti-slip plate 52, a force is applied to the pressure plate 40 in the direction of the fixing frame 32, the pressure plate 40 is reinforced, and the strength and stability of the connection between the pressure plate 40 and the fixing frame 32 are improved.

[0084] In some embodiments, as shown in FIG20 , the fixing frame 32 may be formed with a boss 323 located at the lower end of the support portion, with the surface of the boss 323 flush with the back of the flat plate portion; the support portion is formed with a plurality of second bolt holes, and the boss 323 may be formed with a plurality of third bolt holes; the upper portion of the anti-slip plate 52 is in contact with the flat plate portion, and the lower portion of the anti-slip plate 52 is in contact with the surface of the boss 323, with a plurality of second bolts 521 connected to the second and third bolt holes, respectively. The fixing frame 32 may be formed with a boss 323 at the lower end of the support portion. When the pressure plate 40 is mounted on the support portion, the surface of the boss 323 may be flush with the back of the flat plate portion of the pressure plate 40. The anti-slip plate 52 is mounted on the back of the pressure plate 40 and can simultaneously abut against the back of the boss 323. The support portion can be formed with a plurality of second bolt holes, the boss 323 can be formed with a plurality of third bolt holes, and a plurality of second bolts 521 can be connected to the second bolt holes and the third bolt holes respectively. The flat end of the pressure plate 40 can be provided with a plurality of second through holes, and a plurality of second bolts 521 can pass through the second through holes and connect to the second bolt holes. The upper portion of the anti-slip plate 52 can be connected to the second bolt holes through the pressure plate 40 by the second bolts 521 and fixed to the fixing frame 32. The lower portion of the anti-slip plate 52 can be directly connected to the third bolt hole on the boss 323 by the second bolts 521 and fixed to the fixing frame 32. When the push plate 31 is in the working state, the upper portion of the anti-slip plate 52 can be in contact with the pressure plate 40, directly applying a clamping force to the pressure plate 40, and increasing the number of connecting bolts between the anti-slip plate 52 and the pressure plate 40, which can prevent the vibration of the pressure plate 40 from causing the loosening of the fastening screws 41, making the connection between the pressure plate 40 and the fixing frame 32 more stable. At the same time, the lower part of the anti-slip plate 52 is directly fixedly connected to the boss 323, which can make the installation of the anti-slip plate 52 more stable. When the push plate 31 rotates axially to apply force to the pressure plate 40 and the pressure plate 40 vibrates, the lower part of the anti-slip plate 52 is fixedly connected to the boss 323, which can reduce the vibration transmitted by the pressure plate 40 to the anti-slip plate 52, thereby achieving a better reinforcement effect and improving the strength and stability of the connection between the pressure plate 40 and the fixing frame 32.

[0085] In some embodiments, as shown in FIG20 , the upper end of the anti-slip plate 52 can be flush with the upper end of the flat plate portion. When the push plate 31 is in working condition, the material to be removed hits the push plate 31, and the rotation axis of the push plate 31 is the main force point. When the push plate 31 is in working condition, the rotation axis will apply a force to the pressure plate 40 in the direction away from the fixed frame 32 at the second arc-shaped groove. Setting the upper end of the anti-slip plate 52 to be flush with the upper end of the flat plate portion can make the anti-slip plate 52 as close to the rotation axis as possible. At the position near the rotation axis, a pressing force is applied to the pressure plate 40 in the direction of the fixed frame 32, thereby making the installation of the pressure plate 40 and the fixed frame 32 more stable, effectively preventing the fixing screws from loosening and breaking, and making the reinforcement effect of the anti-slip plate 52 better.

[0086] In some embodiments, as shown in Figures 21 and 22, the reinforcement assembly 50 may include: an upper clamping plate 522 extending in the width direction and disposed on the back of the flat plate portion; a lower clamping plate 523 extending in the width direction and disposed on the side of the support portion facing away from the pressure plate 40; and two spacers 524 located at opposite ends of the fixing frame 32 in the width direction and disposed between the upper clamping plate 522 and the lower clamping plate 523. The upper clamping plate 522 and the lower clamping plate 523 are fixed to the spacers 524 by bolts. The upper clamping plate 522 and the lower clamping plate 523 may extend in the width direction and be parallel to each other, and are respectively disposed on the back of the flat plate portion and the side of the support portion facing away from the pressure plate 40, so that the flat plate portion of the pressure plate 40 and the support portion of the fixing frame 32 are located between the upper clamping plate 522 and the lower clamping plate 523. Two pads 524 are provided, located at both ends of the fixing frame 32 in the width direction, and the two pads 524 are both provided between the upper clamping plate 522 and the lower clamping plate 523. The upper clamping plate 522, the lower clamping plate 523 and the pads 524 are fixedly connected by bolts. The thickness of the pads 524 can be equal to or slightly smaller than the thickness of the connection between the flat plate part and the support part, so that the upper clamping plate 522 can abut against the back side of the flat plate part, and the lower clamping plate 523 can abut against the side of the support part away from the pressure plate 40, clamping the pressure plate 40 and the fixing frame 32 from both sides, thereby reinforcing the pressure plate 40. In the case where the anti-slip plate 52 is provided on the back of the pressing plate 40, the thickness of the pad 524 can be equal to or slightly smaller than the thickness of the anti-slip plate 52, the connection between the flat plate portion and the support portion, so that the upper clamping plate 522 abuts against the side of the anti-slip plate 52 facing away from the pressing plate 40, and the lower clamping plate 523 abuts against the side of the support portion facing away from the pressing plate 40, thereby clamping the pressing plate 40 and the fixing frame 32 while reinforcing the anti-slip plate 52. By providing the upper clamping plate 522, the lower clamping plate 523 and the pad 524, the pressing plate 40 and the fixing frame 32 can be clamped from the back of the pressing plate 40 and the side of the fixing frame 32 facing away from the pressing plate 40, preventing the fastening screws 41 from loosening, improving the stability of the installation of the fastening screws 41, and thus improving the strength and stability of the connection between the pressing plate 40 and the fixing frame 32. The upper and lower clamping plates 522 and 523 clamp the pressing plate 40 and the fixing frame 32. If the bolts connecting the upper and lower clamping plates 522, 523, and the spacers 524 do not fall off, it can be confirmed that the connection between the pressing plate 40 and the fixing frame 32 is stable and the fastening screws 41 are not falling off. The spacers 524 are located on both sides of the material sorting device 100 for easier observation.

[0087] The material sorting device 100 disclosed in the present invention can include a sorting unit provided with multiple push plates 31 as shown in Figures 19 and 20, or can include multiple sorting units arranged side by side as shown in Figure 21. When the pressure plate 40 is reinforced by the upper splint 522, the lower splint 523 and the pad 524, the upper splint 522 and the lower splint 523 can extend in the width direction to cover each sorting unit, so that the upper splint 522 and the lower splint 523 can integrate multiple sorting units and can simultaneously reinforce multiple sorting units arranged side by side. Multiple sorting units have a larger size in the width direction, and the situation of the pressure plate 40 located in the middle is not easy to observe. By providing the upper splint 522, the lower splint 523 and the pad 524, not only can the pressure plate 40 be further reinforced, but also the pads 524 and bolts provided on both sides of the material sorting device 100 can be used to easily observe and confirm whether loosening or falling off occurs, thereby avoiding device failure.

[0088] In some embodiments, as shown in FIG19 , the material sorting device 100 may further include a wedge-shaped locking washer 90 disposed between the fastening screw 41 and the pressure plate 40. The upper and lower surfaces of the wedge-shaped locking washer 90 are both serrated. The wedge-shaped locking washer 90 has two layers, and the serrated contact surfaces of the two layers of wedge-shaped locking washers 90 cooperate with each other. The wedge-shaped locking washer 90 may be two layers, and the upper and lower surfaces of each layer of wedge-shaped locking washers 90 may both be serrated. The serrations of the contact surfaces of the two layers of wedge-shaped locking washers 90 may cooperate with each other. The wedge-shaped locking washer 90 may be disposed between the fastening screw 41 and the pressure plate 40. When the fastening screw 41 is tightened, the serrations of the contact surfaces between the two layers of washers are locked, and the upper and lower serrated surfaces of the wedge-shaped locking washer 90 can lock the fastening screw 41 and the pressure plate 40. The serration angle of the contact surfaces of the two layers of wedge-shaped locking washers 90, i.e., the wedge angle, can be greater than the thread lead angle of the fastening screw 41. When the fastening screw 41 tends to loosen due to rotation, the wedge-shaped locking washer 90 can prevent the fastening screw 41 from loosening due to the wedge-locking effect and preload force. The wedge-shaped locking washer 90 can also be installed at other bolted joints, such as between the first bolt 51 and the curved portion, or between the second bolt 521 and the anti-slip plate 52. By installing a wedge-shaped self-locking washer, the fastening screw 41 can be prevented from loosening due to rotation, thereby increasing the tensile strength of the connection between the fastening screw 41 and the mounting bracket 32 ​​and improving installation stability.

[0089] As shown in Figures 23 and 24, the material sorting device 100 includes a base 11, a fixed frame 32 fixed to the base 11, a push plate 31 hinged to the fixed frame 32, and a driving member 33 hinged to the base 11 at one end and to the push plate 31 at the other end. The specific shape of the base 11 is not limited and can be selected according to actual needs, such as a plate-shaped structure or a frame structure with a mounting surface. The number of push plates 31 can be selected to be one or more, and when there are multiple push plates 31, multiple push plates 31 can be hinged to the fixed frame 32 in a row. The driving member 33 includes a linear drive mechanism such as a cylinder or a hydraulic cylinder, and relies on the linear drive mechanism to drive the push plate 31 to perform a reciprocating flipping motion relative to the fixed frame 32, so that the push plate 31 can selectively change the motion trajectory of the passing material.

[0090] Next, the operating principle of the material separation device 100 will be described using copper ore 200a or iron ore 200b as examples. During operation, if the material passing through the material separation device 100 is copper ore 200a, the material separation device 100 will not be activated, thereby not affecting the movement of the copper ore 200a. However, if the material passing through the material separation device 100 is iron ore 200b, the driving member 33 will drive the push plate 31 to flip outward, forcing the push plate 31 to rebound and / or push, causing the iron ore 200b to follow a different trajectory than the copper ore 200a, thereby separating the two materials.

[0091] Specifically, the push plate 31 can alter the trajectory of passing materials in two ways. First, the push plate 31 can be tilted outward and stopped in a position that blocks the smooth passage of materials, allowing the passing materials to rebound upon impact with the push plate 31 and change their trajectory. Second, the push plate 31 can be tilted outward to actively block and push the passing materials, allowing the materials to change their trajectory upon impact with the push plate 31 through both rebound and propulsion forces.

[0092] Based on this, the material sorting device 100 mentioned in this embodiment does not hinge the end of the driving member 33 away from the push plate 31 to the fixed frame 32 as in the prior art. Instead, the end is hinged to the base 11, so that the impact force generated by the push plate 31 when colliding with the material can be transmitted to the base 11 more quickly and directly, reducing the force on the connection between the fixed frame 32 and the base 11, and improving the force distribution of the hinge between the driving member 33 and the fixed frame 32. This can avoid the risk of cracks or breakage in the connection between the fixed frame 32 and the base 11 and the hinge between the driving member 33 and the fixed frame 32, which is conducive to improving the service life of the material sorting device 100. In addition, because the arrangement slope of the driving member 33 in this embodiment is lower than that of the corresponding prior art, it is conducive to making the overall structure of the material sorting device 100 more compact.

[0093] Next, an exemplary description of the fixing frame 32 is given with reference to Figures 23 and 24. The fixing frame 32 includes an upright portion 321 vertically connected to the base 11, and an inclined portion 322 connected to the upright portion 321 and used to mount the push plate 31. The inclined portion 322 is inclined relative to the upright portion 321 toward the side where the driving member 33 is located, and the acute angle formed with the selected plane is 25° to 90°, wherein the selected plane is a plane parallel to the base 11 and passing through the inclined portion 322 of the fixing frame 32. The inclined portion 322 can guide accidentally fallen materials to slide downward and prevent materials or foreign matter from accumulating here and interfering with the operation of the material sorting device 100. In addition, by setting the inclined portion 322, the fixing frame 32 can reasonably avoid the material throwing path a to avoid interfering with the falling material.

[0094] Preferably, the inclined portion 322 includes a fixed portion fixedly connected to the upright portion 321 and a snap-fit ​​portion detachably connected to the fixed portion. The fixed portion and the snap-fit ​​portion are used to clamp the pins passing through each push plate 31, so that each push plate 31 can be flipped relative to the fixing frame 32 around the corresponding pin. The connection between the fixed portion and the snap-fit ​​portion can be a screw connection or a lock connection, etc.

[0095] Next, the aforementioned drive member 33 will be described in detail with reference to Figures 23 and 24 . As shown in Figures 23 and 24 , the drive member 33 includes a cylinder 331 and an electromagnetic reversing valve 334 for controlling the operating state of the cylinder 331. The electromagnetic reversing valve 334 is generally a reversing valve with three or more operating states, such as a two-position, five-way reversing valve. When the electromagnetic reversing valve 334 is in a first operating state, the piston rod of the cylinder 331 begins to extend outward and pushes the push plate 31 to rotate outward. When the electromagnetic reversing valve 334 is in a second operating state, the piston rod of the cylinder 331 retracts inward and pushes the push plate 31 to rotate inward. When the electromagnetic reversing valve 334 is in a third operating state, the piston rod of the cylinder 331 stops operating and maintains the push plate 31 in its current position. It is worth noting that the cylinder mentioned in this embodiment can also be replaced by a hydraulic cylinder or an electric cylinder.

[0096] As an example, the electromagnetic reversing valve 334 is directly or indirectly fixed to the cylinder 331. For example, the electromagnetic reversing valve 334 is directly fixed to the cylinder 331 by welding or bolting. For another example, the electromagnetic reversing valve and the cylinder 331 can also be simultaneously fixed to the adapter plate 336 by welding or bolting. During operation, the cylinder 331 needs to swing back and forth to accommodate the flipping motion of the push plate 31 in addition to its telescopic motion. Therefore, when the electromagnetic reversing valve 334 is directly or indirectly fixed to the cylinder 331, this fixing method can prevent fatigue damage to the transmission pipeline between the electromagnetic reversing valve 334 and the cylinder 331 due to this swinging motion.

[0097] As an example, the drive member 33 also includes a supply line 335 connected to the electromagnetic reversing valve 334 and providing gas thereto. The supply line 335 includes a flexible tube having a curved portion located between the base 11 and the electromagnetic reversing valve 334. Schematically, the curved portion can be selected to be U-shaped, S-shaped, or spiral-shaped. When the electromagnetic reversing valve 334 swings again during the extension and contraction process, the flexible tube can avoid fatigue damage (including breakage of the joint, etc.) by stretching or re-bending the curved portion, thereby increasing the service life of the drive member 33 and reducing the cost of its repair and maintenance. Preferably, the supply line 335 may also include a channel 1a provided in the base 11, one end of the channel 1a being used to receive high-pressure gas, and the other end being used to connect the end of the flexible tube away from the electromagnetic reversing valve 334. The use of the channel 1a can control the arrangement position of the flexible tube and effectively avoid fatigue damage to the flexible tube.

[0098] As an example, the material sorting device 100 may further include an air supply station, which mainly includes an air compressor and an air storage tank connecting the air compressor and the cylinder 331. In actual use, if the application site of the material sorting device has an air supply station, the material sorting device may not include the air supply station and use the air supply station in the application site.

[0099] In this embodiment, as shown in Figures 23 and 24, the material sorting device may further include a cover assembly 70 connected to the fixing frame 32 and the base 11. The cover assembly 70, the base 11 and the fixing frame 32 together form a accommodating chamber for accommodating the driving member 33. The cover assembly 70 includes a material guide slope 71 and an opening provided on the material guide slope 71 and for partially passing through the driving member 33. The cover assembly 70 can prevent accidentally fallen materials from entering the above-mentioned accommodating chamber and interfering with the movement of the driving member 33. The material guide slope 71 can guide accidentally fallen materials to slide downward and prevent the materials from accumulating on the cover assembly 70. Preferably, a dust-proof brush 72 in contact with the driving member 33 is provided at the location of the opening. The dust-proof brush 72 not only does not hinder the movement of the driving member 33, but also prevents foreign matter such as dust and particles from falling into the above-mentioned accommodating chamber and affecting the movement of the driving member 33.

[0100] As shown in Figure 25, to further reduce the risk of cracks or breaks in the hinge between the driver 33 and the fixed frame 32, the material sorting device 100 also includes a first connecting member 81 disposed on the base 11, a second connecting member 82 disposed at the end of the driver 33 near the base 11, a hinge shaft 83 extending through the first and second connecting members 81, 82, and a shock-absorbing sleeve 84 disposed within the first and / or second connecting members 81, 82 and sleeved over the hinge shaft 83. The first connecting member 81, the second connecting member 82, the hinge shaft 83, and the shock-absorbing sleeve 84 function as a hinge between the driver 33 and the fixed frame 32, ensuring that the driver 33 can rotate relative to the fixed frame 32. The shock-absorbing sleeve 84 primarily functions to reduce the risk of cracks or breaks in the hinge between the driver 33 and the fixed frame 32. Preferably, the shock-absorbing sleeve 84 is primarily made of polyurethane or other high-strength, elastic, and wear-resistant materials. Since polyurethane has high strength, high elasticity and high wear resistance, the shock-absorbing bushing 84 made of it has excellent shock-absorbing performance, which can further reduce the risk of cracks or breakage of the hinge between the driving member 33 and the fixing frame 32.

[0101] In some embodiments of the present disclosure, as shown in Figures 28 and 28, the driving member 33 may further include a transmission connection mechanism 332, the first connection end of the transmission connection mechanism 332 is hinged to the fixed frame 32, and the second connection end opposite to the first connection end is used to support the push plate 31 from the back side of the push plate 31; when the push plate 31 is lifted, the vertical distance between the second connection end and the first connection end along the vertical line perpendicular to the push plate 31 is less than the vertical distance between the cylinder 331 and the first connection end in the extension and contraction direction.

[0102] The transmission connection mechanism 332, the first connection end 3321 of the transmission connection mechanism 332 can be hinged to the fixed frame 32, and the hinge point can be set at the middle part of the fixed frame 32 in the direction perpendicular to the ground. The transmission connection mechanism 332 can rotate around the hinge point, so that the transmission connection mechanism 332 can rotate around the first connection end 3321. The second connection end 3322 of the transmission connection mechanism 332 opposite to the first connection end 3321 can be used to support the push plate 31 from the back of the push plate 31. It should be noted that the front side of the push plate 31 in the present disclosure can be the side of the push plate 31 that contacts the material to be removed when the push plate 31 is in the raised state, and the back side of the push plate 31 can be the side of the push plate 31 that is connected to the transmission mechanism. The second connection end 3322 of the transmission connection mechanism 332 can support the push plate 31 from its backside. Under the pushing action of the cylinder 331, the second connection end 3322 of the transmission connection mechanism 332 can lift the push plate 31 from its backside, causing the push plate 31 to flip upward and strike the material to be removed. Furthermore, the transmission connection mechanism 332 can maintain the push plate 31 in its raised position under the action of the cylinder 331. When the push plate 31 removes the material to be removed, the transmission connection mechanism 332 rotates about the first connection end 3321, lifting the push plate 31 upward, causing the second connection end 3322 to lift upward and thus support the push plate 31.

[0103] The cylinder 331 can be hinged at one end to the base 11 and at the other end to the transmission connection mechanism 332. The cylinder 331 can be used to drive the transmission connection mechanism 332 to rotate about the first connection end 3321, thereby lifting and supporting the push plate 31 via the second connection end 3322 of the transmission connection mechanism 332. When the push plate 31 is raised, the vertical distance between the second connection end 3322 and the first connection end 3321 along a line perpendicular to the push plate 31 is less than the vertical distance between the cylinder 331 and the first connection end 3321 in the direction of extension and contraction. The cylinder 331 can be used to drive the push plate 31 via the transmission connection mechanism 332. One end of the cylinder 331 can be hinged to the base 11, and the cylinder 331 can rotate about the hinge point, so that the angle at which the cylinder 331 applies force to the transmission mechanism can be changed according to different circumstances. The other end of the cylinder 331 can be hinged to the transmission connection mechanism 332. The piston rod of the cylinder 331 is pushed outward, pushing the transmission connection mechanism 332 to rotate about the first connection end 3321 through the hinge point between the cylinder 331 and the transmission connection mechanism 332, thereby lifting the second connection end 3322 and supporting the push plate 31. The second connection end 3322 of the transmission connection mechanism 332 can contact and support the push plate 31 in a variety of ways. Because the push plate 31 rotates about the hinge point between the push plate 31 and the fixed frame 32, and the transmission connection structure rotates about the hinge point of the first connection end 3321 under the action of the cylinder 331 to push the push plate 31 from the back side, the second connection end 3322 of the connection mechanism must maintain contact with the push plate 31 during the pushing process, and the relative angle between the two can change simultaneously with the flipping of the push plate 31.

[0104] As shown in Figures 28 and 29, when the push plate 31 is raised, the transmission connection mechanism 332 can be regarded as a lever, with the fulcrum being the hinge point between the first connection end 3321 and the fixed frame 32. When the material to be rejected hits the push plate 31, the impact force borne by the push plate 31 is transmitted to the transmission connection mechanism 332 through the second connection end 3322 of the transmission connection mechanism 332, and the direction of the impact force is perpendicular to the push plate 31. The cylinder 331 pushes the transmission connection mechanism 332, providing a supporting force for the transmission connection mechanism 332. The supporting force acts at the hinge point with the transmission connection mechanism 332 and acts in the direction of extension of the piston rod of the cylinder 331. At the moment when the push plate 31 is subjected to the impact force, part of the impact force is also transmitted to the cylinder 331 through the transmission connection mechanism 332, in the same direction as the extension direction of the piston rod of the cylinder 331. As shown in FIG29 , the distance from the fulcrum to the line of action of the striking force is the first lever arm L1 of the striking force, and the distance from the fulcrum to the line of action of the supporting force is the lever arm L2 of the striking force borne by the cylinder 331. The lever arm L1 is greater than the lever arm L2. Therefore, when the push plate 31 is raised and the material to be removed hits the push plate 31, the striking force borne by the cylinder 331 is less than the force transmitted by the push plate 31 to the transmission connection mechanism 332, and the fixed frame 32 can bear part of the impact. Compared with the related art, the cylinder 331 is directly supported on the back of the push plate 31 or the cylinder 331 is directly rigidly connected to the push plate 31. The cylinder 331 needs to bear almost all the impact force. However, the embodiment of the present disclosure can share part of the impact force through the transmission connection mechanism 332, reducing the lever arm of the supporting force of the cylinder 331 in the form of a lever, thereby reducing the impact force on the cylinder 331 and effectively extending the life of the cylinder 331. The cylinder 331 extends and pushes the transmission connection mechanism 332, which supports the push plate 31 through the transmission connection mechanism 332, so that the push plate 31 is lifted up. In the form of a lever, the force arm of the supporting force of the cylinder 331 is reduced. When pushing the push plate 31 to lift up, the cylinder 331 is more labor-saving, which effectively extends the service life of the cylinder 331.

[0105] As shown in Figures 26 and 26 , the embodiment of the present disclosure can provide a material sorting machine 200. As shown in the figure, the material sorting machine 200 includes a feeding mechanism 250, a conveying mechanism 210, a detection mechanism 220, a control mechanism 260, a pushing assembly 30 and a blowing assembly 20.

[0106] Feeding mechanism 250 is used to feed the material to be sorted into conveying mechanism 210. The material to be sorted can be ore or other materials, which are not limited in the present embodiment. Feeding mechanism 250 can, for example, include a vibrating distributor that has the functions of vibrating and screening the material to disperse the material into conveying mechanism 210.

[0107] The conveying mechanism 210 is used to convey the material to be sorted fed by the feeding mechanism 250. The conveying mechanism 210 can be, for example, a conveyor belt or a chute, and the disclosed embodiment has no limitation on this. In one embodiment, as shown in the figure, the conveying mechanism 210 can be arranged below the feeding mechanism 250, and the material to be sorted falls from the discharge port of the feeding mechanism 250 to the left end of the conveying mechanism 210 and is transmitted to the right, and finally the material to be sorted can be thrown out from the output end (i.e., the right end) of the conveying mechanism 210 at an initial speed. Through the friction between the conveying mechanism 210 and the material to be sorted, the movement speed and direction of the material to be sorted gradually become consistent with the conveying mechanism 210, reaching a stable state, and being dispersed and spread on the belt or chute, and then detached from the conveying mechanism at the right end of the conveying mechanism 210, thrown out at an initial speed, and moving in a parabolic motion trajectory.

[0108] The detection mechanism 220 is used to detect the material to be sorted transported on the conveying mechanism 210 to detect whether the material to be sorted is material to be eliminated or material that does not need to be eliminated. The material to be eliminated refers to the material to be separated by the separation execution mechanism. The material to be eliminated can be the required material or the non-required material, as long as the material can be sorted. Specifically, as shown in the figure, the detection mechanism 220 can be set above the conveying mechanism 210 to capture images of the material to be sorted to detect whether the material to be sorted is material to be eliminated or material that does not need to be eliminated. For example, the detection mechanism 220 can image the material to be sorted by different spectral technologies, such as X-rays, infrared rays, etc. to obtain an analytical image of the material, and the present disclosed embodiment is not limited in this respect. Furthermore, the detection mechanism 220 can capture images of the material to be sorted transported on the conveying mechanism 210 to obtain physical information of the material to be eliminated, such as size, position, weight, etc.

[0109] The control mechanism 260 is used to control the ejection assembly 30 or the blowing assembly 20 to perform a separation action based on the detection results of the detection mechanism 220. Specifically, the control mechanism 260 can determine the material to be eliminated based on the image collected by the detection mechanism 220, and further obtain the physical information of the material to be eliminated. Then, based on the physical information of the material to be eliminated, the separation execution mechanism in the ejection assembly 30 and the blowing assembly 20 that will perform separation on the material to be eliminated is determined according to the separation strategy. Finally, the control mechanism 260 instructs the determined separation execution mechanism to perform separation on the material to be eliminated. The control mechanism can generally include a processor (such as a PLC, MCU, CPU, etc.), a memory, and electronic components connected to the processor, etc. These components are well known to those skilled in the art and will not be described in detail here.

[0110] The ejector assembly 30 and the blower assembly 20 can be separate actuators suitable for materials of different particle sizes. In some embodiments, as shown, the ejector assembly 30 is suitable for larger or heavier materials, while the blower assembly 20 is suitable for smaller or lighter materials. Both the ejector assembly 30 and the blower assembly 20 are positioned below and to the right of the conveyor mechanism 210. Based on the instructions of the control mechanism 260, they separate the materials to be rejected, for example, by impacting or blowing, causing the materials to deviate from their original trajectory and fall into a designated location, such as a corresponding receiving hopper.

[0111] According to the material sorting machine 100 provided above, by configuring two separation actuators and performing real-time identification of materials to be rejected based on a separation strategy, the materials to be rejected can be treated differently to meet the sorting requirements of materials of different particle sizes, and separated by the appropriate separation actuator, thereby saving energy. For example, the use of a push plate mechanism for larger or heavier materials can significantly reduce energy consumption compared to a blowing mechanism, thereby reducing costs. The use of a blowing mechanism for smaller or lighter materials can achieve more accurate and faster sorting.

[0112] As shown in Figures 2, 3, 7 and 8, the material sorting machine 200 includes a mounting portion on which the ejection assembly 30 and the blowing assembly 20 are mounted.

[0113] The ejection assembly 30 may include a push plate 31 and a driving member 33. The push plate 31 is used to impact the material to be rejected under the drive of the driving member 33 to change the motion trajectory of the material to be rejected, so that the material to be rejected deviates from the original parabolic motion trajectory and falls into a specified position.

[0114] The push plate 31 can be mounted on the frame assembly via the first hinge portion 3111 of the mounting portion. The mounting portion serves as a support, and the first hinge portion 3111 can be mounted on the mounting portion, providing rotational support for the push plate 31. The first hinge portion 3111 can be positioned perpendicular to the conveying direction (e.g., horizontally) of the conveyor mechanism, and can be positioned along the horizontal direction ( FIG. 2 ), i.e., the width of the conveyor mechanism.

[0115] The ejection assembly 30 includes several push plates 31 arranged side by side and spaced apart along the axis of the first hinge portion 3111 (Figure 2). Each push plate 31 is connected to the first hinge portion 3111 so as to swing about the axis of the first hinge portion 3111. This swinging motion impacts the material to be removed, thereby altering its trajectory and causing it to deviate from its original parabolic trajectory. Because the materials vary in diameter and shape, each occupying a different amount of space. Therefore, each push plate 31 can be independently controlled. Based on the material's characteristics, such as size and position, the corresponding push plate 31 is controlled to separate the material. In some embodiments, a gap is provided between any two adjacent push plates 31, allowing each push plate 31 to swing independently of the other, thus preventing interference between adjacent push plates 31. Each push plate 31 can swing individually, or several can swing together. For example, when the material diameter is almost equal to the width of one push plate 31, only one push plate needs to be controlled; if the material diameter is greater than the width of one push plate 31, two or more push plates may need to be controlled simultaneously.

[0116] The driving member 33 may include a plurality of driving members corresponding to the push plates, configured to drive the push plates 31 to swing and thereby change the trajectory of the material to be removed. In this embodiment, each driving member 33 may be a telescopic length adjustment member. The fixed end of the driving member 33 may be disposed on the base 11, and the telescopic end may be connected to the corresponding push plate 31, so that the push plate can be pulled to swing by adjusting the length of the telescopic length adjustment member. The driving member 33 may be hingedly connected to the push plate 31 to drive the push plate 31 to swing. Of course, other connection methods are also possible, and this embodiment is not limited to this.

[0117] As shown in Figure 7, the spray assembly 20 includes a valve plate unit 63, a connecting pipe 65, and a nozzle 23. The valve plate unit 63 is mounted on the base 11 and connected to the nozzle 23 via the connecting pipe 65. The connecting pipe 65 can be a flexible hose or a metal tube. Thus, the valve plate unit 63 effectively controls the opening and closing of the spray holes in the nozzle 23. Under the control of the valve plate unit 63, the nozzle 23 sprays gas toward the material to be rejected, thereby changing the trajectory of the material, causing it to deviate from its original parabolic trajectory and land in a designated location.

[0118] The nozzle 23 may include a plurality of injection holes, which are arranged side by side and at intervals in the horizontal direction, that is, arranged in the horizontal direction of Figure 2 and the width direction of the transmission mechanism. In some embodiments, the setting position of the nozzle 23 in the material sorting device 100 is higher than the setting position of the push plate 31 in the material sorting device 100. In this way, it is beneficial to separate the parabolic motion trajectories of the materials targeted by the second separation actuator (blowing component 20) and the first separation actuator (pushing component 30), thereby avoiding collision of materials, changing the motion trajectory, and causing sorting errors. For example, as shown in Figure 26, setting the blowing component 20 at a higher place is beneficial to blowing smaller and lighter materials to a higher motion trajectory b, while setting the pushing component 30 at a lower place can push larger and heavier materials without too much power consumption, and can push the materials to a motion trajectory c that is separated from the motion trajectory a. Those skilled in the art will understand that, depending on different needs, the material along the path motion trajectory b and the material along the path motion trajectory c may fall into the same material receiving area (for example, the second recovery area 232 in FIG. 26 , which only distinguishes between materials to be rejected and materials that do not need to be rejected), or may fall into different material receiving areas (for example, further distinguishing between large-particle-size materials to be rejected and small-particle-size materials to be rejected). The embodiments disclosed herein are not limited in this regard.

[0119] Similar to the ejection assembly 30, the opening of each injection hole in the nozzle 23 can also be independently controlled. In some embodiments, the valve plate unit 63 can be a solenoid valve, including multiple solenoid valves, the inlet of each solenoid valve is connected to the air inlet channel and connected to the air source through the air inlet channel, and the outlet of each solenoid valve is connected to the corresponding exhaust channel, and connected to the corresponding injection hole in the nozzle 23 through the exhaust channel and the connecting pipe 65 connected to the exhaust channel. This ensures that each injection hole can be connected to the air source through a fixed solenoid valve, achieving the purpose of each solenoid valve being able to independently control a injection hole. It can be understood that by selecting the solenoid valve to open, the injection hole can be selected for injection, and multiple solenoid valves can also be opened simultaneously to achieve simultaneous injection of multiple injection holes.

[0120] It can be understood that the driving member 33 in the first separation actuator and the valve plate unit 63 in the second separation actuator both perform corresponding actions under the control of the control mechanism 260 to control the execution of the first separation actuator and the second separation actuator.

[0121] The present disclosure also provides a control method that can control a first separation actuator or a second separation actuator to perform a separation action based on the detection result. The first separation actuator can be a push assembly, and the second separation actuator can be, for example, a blowing assembly.

[0122] As shown in FIG30 , the control method 600 can be executed by, for example, a control mechanism. The control method 600 may include step 610, obtaining physical information of the material to be rejected based on the image of the material to be rejected. As mentioned above, the detection mechanism can capture images of the material to be rejected. The captured images can be transmitted to the control mechanism for analysis and judgment. For example, the control mechanism can first distinguish the material to be rejected into material to be rejected and material that does not need to be rejected, so as to distinguish between waste and ore. The material to be rejected can be ore, and the material that does not need to be rejected can be waste; and vice versa. Furthermore, for the material to be rejected, the control mechanism can further obtain its physical information. The physical information may include, but is not limited to: material size (including three-dimensional size), material weight, material position, center of mass position, thickness information, vertical projection information, etc. The material size may also include the particle size of the material.

[0123] In step 620 , based on the physical information of the material to be rejected, a separation execution mechanism, one of the first separation execution mechanism and the second separation execution mechanism, which will perform separation on the material to be rejected is determined according to the separation strategy.

[0124] In some embodiments, the separation strategy may include: determining to use a first separation execution mechanism for materials to be rejected whose physical information meets a predetermined condition; and determining to use a second separation execution mechanism for materials to be rejected whose physical information does not meet the predetermined condition.

[0125] In some embodiments, the first separation actuator is a push assembly suitable for large or heavy materials; the second separation actuator is a blow assembly suitable for small or light materials. In this case, the predetermined conditions may include any of the following: the material size exceeds a first predetermined size; or the material size exceeds a second predetermined size but does not exceed the first predetermined size, and the material weight exceeds the first predetermined weight.

[0126] The preset dimension for the separation can be set with reference to the width of the push plate of the ejection assembly. For example, the first preset dimension can be Rd times the width of the push plate in the ejection assembly, where Rd>1. In some embodiments, the value of Rd can range from 1.5 to 2.5, preferably 2. Thus, when the material dimension (e.g., the width dimension, i.e., the dimension perpendicular to the conveying direction within the conveying surface of the conveyor mechanism) of the material to be rejected exceeds Rd times the width of the push plate, separation is determined to be performed using the ejection assembly.

[0127] The second preset size can be set to the push plate width. Thus, when the size (e.g., width) of the material to be rejected is greater than the push plate width but less than Rd times the push plate width, a determination is made as to whether the material weight exceeds the first preset weight Md. If so, separation is performed using the ejection assembly; otherwise, separation is performed using the blowing assembly. The first preset weight Md can be set, for example, to 1 kg to 5 kg, preferably 2 kg.

[0128] Furthermore, the control mechanism may also determine the push plate or injection hole that needs to be opened based on the position of the material to be rejected (eg, the center of mass position).

[0129] In step 630, the control mechanism instructs the determined separation execution mechanism to perform separation on the corresponding materials to be rejected. Depending on the different separation execution mechanisms, the control mechanism may also instruct corresponding separation execution parameters.

[0130] In some embodiments, when it is determined that the material to be rejected is to be separated by a second separation actuator (e.g., a blowing component), the control mechanism can also determine an air spray coefficient based on the physical information of the material to be rejected, wherein the air spray coefficient indicates the intensity of the air spray control; and send an air spray separation instruction and an air spray coefficient to the second separation actuator. Specifically, a ratio can be calculated based on the weight and particle size of the material, and this ratio corresponds to the preset air spray coefficient. The air spray coefficient is generally between 0.5 and 1.5. It can be understood that the larger the ratio, the larger the air spray coefficient, and the greater the intensity of the air spray control.

[0131] In some other embodiments, when it is determined that the material to be rejected is to be separated by a first separation actuator (such as a push-out assembly), the control mechanism can also determine one or more push plates to perform the separation based on the center of mass position information and material width of the material to be rejected; and send a push plate separation instruction to the driving parts of the determined one or more push plates.

[0132] Therefore, the control method of the embodiment of the present disclosure can perform real-time identification and differentiated processing of materials to be rejected according to the separation strategy to meet the sorting requirements of materials of different particle sizes, separate them with suitable separation actuators, and save energy consumption.

[0133] Taking into account that the particle size distribution of the material to be eliminated may change, for example, the particle size distribution of materials sorted at different time periods in the same batch may be different, and the particle size distribution of materials in different batches may also be different. Therefore, optionally or additionally, in some embodiments, the above-mentioned separation strategy for determining whether to use the first separation actuator or the second separation actuator for the material to be eliminated can be dynamically adjusted or determined. For example, at the initial stage of material sorting, the initial separation strategy can be determined based on the material particle size distribution. It can be understood that the initial separation strategy can also be preset based on experience, or inherit the settings of the previous sorting operation. For another example, during the material sorting process, the separation strategy can be updated based on changes in the material particle size distribution.

[0134] Furthermore, a separation strategy can be determined based on the overall particle size distribution of the material to be rejected, combined with the physical configuration of the first and second separation actuators (e.g., push plate width, nozzle spacing, etc.). Determining the separation strategy can include determining various preset parameters used for separation in the aforementioned predetermined conditions, such as the Rd multiple of the first preset size, the first preset weight Md, etc.

[0135] Since the energy consumption required by the first separation actuator and the second separation actuator is different, the optimal energy consumption ratio can be achieved by allocating the amount of material separated by the first separation actuator and the second separation actuator. For example, in some embodiments, the various preset parameters used for the demarcation in the aforementioned predetermined conditions can be determined based on the overall particle size distribution of the material to be removed, so that the ratio of the amount of material separated by the ejection assembly and the blowing assembly is close to a predetermined energy consumption ratio. In some embodiments, the predetermined energy consumption ratio can range from approximately 20% to 60%. In some embodiments, the predetermined energy consumption ratio can be set to 30%.

[0136] In addition to determining the separation strategy according to the above method at the initial stage of material sorting, optionally or additionally, in some embodiments, the separation strategy can be updated in real time and dynamically based on changes in the material particle size distribution during the material sorting process.

[0137] In these embodiments, the aforementioned control method may further include: counting the amount of materials separated by the first separation execution mechanism and the second separation execution mechanism respectively; and updating the separation strategy based on the counted amount of materials.

[0138] Specifically, the above statistical operation can be performed each time after the separation execution mechanism of the material to be rejected is determined. In some implementations, two counters can be set to respectively count the number of materials separated by the first separation execution mechanism and the number of materials separated by the second separation execution mechanism.

[0139] In some embodiments, based on the counted material quantity, updating the separation strategy may include: determining the deviation of the ratio of the quantity of material separated by the first separation actuator to the quantity of material separated by the second separation actuator relative to a predetermined energy consumption ratio; and updating the separation strategy in response to the magnitude of the deviation exceeding a specified threshold.

[0140] The above-mentioned determination of the material quantity ratio can be performed in real time, for example, after each statistical operation, or can be performed periodically, for example, at regular intervals, without limitation in the present embodiment. When the magnitude of the deviation of the material quantity ratio from the predetermined energy consumption ratio exceeds a specified threshold, the separation strategy can be updated to better adapt to the current particle size distribution of the material to be rejected. The specified threshold can be, for example, 3% to 10%, such as 5%.

[0141] In some embodiments, in response to the magnitude of the deviation exceeding a specified threshold, updating the separation strategy may include: determining an adjustment direction of preset parameters for demarcation, such as a first preset size, a second preset size and / or a first preset weight, based on the direction of the deviation; determining an adjustment magnitude of the aforementioned preset parameters for demarcation based on the magnitude of the deviation; and adjusting these preset parameters based on the determined adjustment direction and adjustment magnitude.

[0142] In one example, assuming the number of materials separated by the first separation mechanism is 20 and the number of materials separated by the second separation mechanism is 90, the ratio of the two material quantities is 20 / 90 = 22.22%. Assuming the predetermined energy consumption ratio is 30%, the deviation of the material quantity ratio from the predetermined energy consumption ratio is -7.78%. Assuming the specified threshold is 5%, the magnitude of the deviation (7.78%) exceeds the specified threshold, requiring an update to the separation strategy. In this example, the direction of the deviation is negative, indicating that the number of materials separated by the first separation mechanism needs to be increased. Therefore, the decision criteria for the first separation mechanism can be relaxed, for example, by reducing the Rd multiple in the first preset size and / or reducing the first preset weight. The parameter adjustment range can be set based on the deviation range or adjusted according to a predetermined step size. Those skilled in the art can design corresponding adjustment schemes based on actual needs. In this example, assuming the original Rd is 2 and only one step size (0.1) is adjusted at a time, Rd can be adjusted to 1.9. The value of the first preset weight Md can be similarly adjusted according to the adjustment principle.

[0143] It is understood that when the ratio of the amount of material separated by the first separation actuator to the amount of material separated by the second separation actuator is greater than a predetermined energy consumption ratio, and the magnitude of the deviation exceeds a specified threshold, the separation strategy needs to be updated. To this end, the decision conditions for the first separation actuator can be tightened, for example, by increasing the Rd multiple in the aforementioned first preset size and / or increasing the first preset weight. Detailed examples are not provided here.

[0144] Those skilled in the art will appreciate that the activation conditions for the above-mentioned updating separation strategy may also vary. For example, updating is performed only when the magnitude of the deviation exceeds a specified threshold for multiple consecutive times to avoid frequent adjustments.

[0145] In summary, in some embodiments of the present disclosure, by dynamically determining and / or adjusting the separation strategy, changes in the particle size distribution of the material to be removed can be matched in a timely manner to achieve optimal power consumption.

[0146] Figure 31 shows another exemplary flow chart of a control method for a material sorting machine according to some embodiments of the present disclosure. It is understood that the example of Figure 31 is a specific implementation of the embodiment described above in conjunction with Figure 30, and therefore, the description of Figure 31 above also applies to Figure 32.

[0147] As shown in the figure, the control method 900 starts at step 910 and then proceeds to step 920, where the image of the material to be rejected is analyzed, and physical information of the material to be rejected is obtained based on the image of the material to be rejected, such as calculating the three-dimensional size, particle size, weight, center of mass position, etc.

[0148] Next, in step 930, a determination is made as to whether the size of the material to be rejected exceeds a first predetermined size. For example, does the ratio of the material width D to the push plate width d exceed a specified multiple Rd, i.e., D / d > Rd? If so, the first separation actuator (in this embodiment, the ejector assembly) is determined to be used. The method then proceeds to step 950, where a push plate separation instruction is sent to the ejector assembly.

[0149] If the result of the judgment in step 930 is negative, the method proceeds to step 940, where it further determines whether the size of the material to be rejected, while not exceeding the first preset size, exceeds the second preset size, and whether the material weight M exceeds the first preset weight Md. In this embodiment, the second preset size is set to the push plate width d. For example, this judgment can be expressed as D>d and M>Md. If so, the first separation actuator (here, the ejection assembly) can also be determined to be used. The method also proceeds to step 950, where a push plate separation instruction is sent to the ejection assembly.

[0150] If the result of the determination in step 940 is negative, the second separation actuator (in this embodiment, the blow assembly) is determined to be used, and the method then proceeds to step 960, where an air jet separation instruction is sent to the blow assembly. Furthermore, when it is determined that the blow assembly is to be used to separate the material to be rejected, an air jet coefficient can be determined based on the physical information of the material to be rejected, and this air jet coefficient is sent to the blow assembly to control the intensity of the air jet.

[0151] Furthermore, after determining the separation actuator used for the material to be removed, the method also includes step 970, counting the number and proportion of materials separated by the first separation actuator (push-up assembly) and the second separation actuator (blowing assembly) respectively. For example, the number of materials separated by the push-up assembly is Nb, and the number of materials separated by the blowing assembly is Nq, and the ratio of the two, Nb / Nq, is calculated.

[0152] Finally, in step 980, the statistical data Nb / Nq is analyzed to determine whether to update the various demarcation parameters in the separation strategy. If the fluctuation of Nb / Nq relative to the predetermined energy consumption ratio Rn exceeds a certain range, the demarcation parameters in the separation strategy, such as Rd and / or Md, may be adjusted within a limited range.

[0153] Then, in the next round of separation decision, the updated demarcation parameter may be used to make a decision, as indicated by arrows 901 and 902 in the figure.

[0154] Because the spray assembly consumes large amounts of compressed air and electricity to spray materials, it results in low resource utilization and high costs. Furthermore, some small-particle materials are not suitable for the spray assembly, such as those with small particles but large thicknesses, which the spray assembly struggles to separate. Therefore, it is desirable to prioritize the ejector assembly as the separation actuator in material separation mechanisms. This approach can minimize energy consumption while ensuring the separation of materials across a wide range of particle sizes, ultimately achieving energy conservation and environmental protection.

[0155] To this end, the present disclosure also provides other separation strategies. Figure 32 shows a flow chart of a control method 700 according to an embodiment of the present invention. The control method 700 can be applied to a material sorting device, which includes a push assembly and a blowing assembly.

[0156] At step 702, the vertical projection information of the material to be eliminated can be obtained. As mentioned above, when the material to be sorted passes through the detection mechanism, the detection mechanism can collect the vertical projection information of the material to be sorted. The light emitted by the transmitter of the detection mechanism passes through the material to be sorted and is received by the receiver on the other side of the material to be sorted, thereby forming a projection image. Vertical projection refers to the projection produced by mutually parallel light rays, and the parallel light rays are perpendicular to the projection surface. The vertical projection information can be detected from top to bottom, or from bottom to top, or from any desired direction, and the embodiments of the present invention are not limited thereto. It should be understood that the above example is only one method of detecting the vertical projection information of the material, and any appropriate method can be used to detect the vertical projection information of the material. The control mechanism can obtain the vertical projection information of the material to be eliminated from the detection mechanism or the information storage device.

[0157] At step 704, it can be determined whether there is material that does not need to be rejected within the safety range of the material to be rejected. In order to give priority to selecting the push-up assembly as the separation actuator, it is necessary to ensure that there is no material that does not need to be rejected within the safety range of the material to be rejected, so that the push plate will not hit the material that does not need to be rejected at the same time when hitting the material to be rejected. The safety range can be the striking range of all push plates corresponding to the vertical projection information of the material to be rejected in the push-up assembly for separating materials. The striking range of the push plate can be the width of the push plate perpendicular to the direction of material travel. Assuming that the vertical projection of the material to be rejected falls within the width range of 5 push plates in the push plate width direction, the safety range is the striking range of the 5 push plates. Therefore, it can be determined whether there is material that does not need to be rejected within the safety range of the material to be rejected based on whether there is a vertical projection of the material that does not need to be rejected within the safety range of the material to be rejected.

[0158] If it is determined at step 704 that no unnecessary material exists within the safety range, at step 706, all push plates in the ejection assembly corresponding to the material to be rejected can be used to separate the material to be rejected. By determining the safety range, regardless of the particle size of the material to be rejected, as long as no unnecessary material exists within the safety range of the material to be rejected, that is, when the ejection assembly uses the push plate to strike the material to be rejected, the unnecessary material will not be mistakenly struck, and the ejection assembly can be used to separate the material to be rejected. Therefore, even if the particle size of the material to be rejected is small, the ejection assembly can be used to separate the small-particle material, while ensuring accurate material separation resolution and improving the utilization rate of the ejection assembly, thereby achieving the goal of saving energy. In addition, by using all push plates corresponding to the material to be rejected, more accurate striking of the material to be rejected can be ensured, reducing the probability of misses.

[0159] If it is determined at step 704 that material that does not need to be rejected exists within the safe range, at step 708, it can be determined whether to use the blowing assembly or the portion of the push plates in the ejection assembly corresponding to the material to be rejected to separate the material to be rejected based on the vertical projection information of the material to be rejected. When material that does not need to be rejected exists within the safe range of the material to be rejected, while ensuring that the material that does not need to be rejected is not mistakenly separated, the portion of the push plates corresponding to the material to be rejected can be preferentially used to separate the material to improve the utilization rate of the push plates. If any push plates in the ejection assembly cannot achieve the purpose of separating the material to be rejected without interference, that is, cannot separate the material to be rejected without striking the material that does not need to be rejected, the blowing assembly can still be used to separate the material to be rejected.

[0160] Figure 33 shows a flow chart of a control method 800 according to another embodiment of the present invention. Steps 802 to 806 are the same as steps 702 to 706 in the method 700 described with reference to Figure 32. To avoid redundancy, the specific details of steps 802 to 806 are not described here.

[0161] In one embodiment, at step 808, the particle size of the material to be rejected may be extracted from the vertical projection information of the material to be rejected. The particle size of the material to be rejected may be the size of the material to be rejected in a direction parallel to the width of the push plate.

[0162] At step 810, it may be determined whether the particle size of the material to be rejected is greater than a particle size threshold. In one embodiment, the particle size threshold may be 3 times or more the width of a single push plate.

[0163] If it is determined at step 810 that the particle size of the material to be rejected is greater than the particle size threshold, at step 812, the ejection assembly may be used to separate the material to be rejected using some of the push plates corresponding to the material to be rejected. Since the blowing assembly consumes a very large amount of gas and power when processing large-particle materials, and the blowing effect may be poor, using the ejection assembly to separate large-particle materials can both save resources and ensure the separation of large-particle materials. In addition, since large-particle materials with a particle size greater than the particle size threshold usually correspond to multiple push plates, even if there is material that does not need to be rejected within the safe range of the material to be rejected, at least one or more push plates located in the middle of the multiple push plates can be selected to separate the material to be rejected without interference.

[0164] In one embodiment, if it is determined at step 810 that the particle size of the material to be rejected is not greater than the particle size threshold, at step 814, the thickness information of the material to be rejected can be obtained and the maximum thickness of the material to be rejected can be extracted from the thickness information. When the material to be sorted passes through the detection mechanism, the detection mechanism can collect the thickness information of the material to be sorted. The transmitter of the detection mechanism is arranged above the transmission mechanism, and emits light from top to bottom. The light is reflected when it encounters the transmission mechanism or the material thereon. The reflected light is received by a receiver also located above the transmission mechanism, thereby obtaining the thickness information of the material. It should be understood that the above example is only one method of detecting the thickness information of the material, and any appropriate method can be used to detect the thickness information of the material. The control mechanism can obtain the thickness information of the material to be rejected from the detection mechanism or the information storage device.

[0165] At step 816, it is determined whether the ratio of the maximum thickness of the material to be rejected to the particle size is greater than a thickness threshold. In one embodiment, the thickness threshold is greater than or equal to 0.5 and less than or equal to 1. If the ratio of the maximum thickness of the material to be rejected to the particle size is greater than the thickness threshold, it means that the material to be rejected is relatively thick and difficult to separate by the blowing assembly. Therefore, the ejection assembly is preferably used to remove such material, which can achieve lower gas and power consumption and better material separation.

[0166] If it is determined at step 816 that the ratio is greater than the thickness threshold, at step 818, based on the vertical projection information of the material to be rejected, it can be determined whether any of the push plates corresponding to the material to be rejected has no material that does not need to be rejected within its striking range. For example, assuming that the vertical projection of the material to be rejected falls within the width range of three push plates in the push plate width direction, the push plates corresponding to the material to be rejected are these three push plates. Then, for each of these three push plates, it can be determined whether any material that does not need to be rejected exists within its striking range. If no material that does not need to be rejected exists within the striking range of a push plate, then this push plate is a push plate that does not have material that does not need to be rejected within its striking range. Thus, it can be determined whether any of the three push plates has no material that does not need to be rejected within its striking range.

[0167] If it is determined at step 818 that there are push plates corresponding to the materials to be rejected that do not have materials that do not need to be rejected within their striking range, at step 812, some of the push plates of the ejection assembly corresponding to the materials to be rejected may be used to separate the materials to be rejected. Since it has been determined that there is at least one push plate that can separate the materials to be rejected without interference, one or more of the at least one push plates may be used to separate the materials.

[0168] 11 and 26 , the material sorting machine 200 includes a conveying mechanism 210, a detection mechanism 220, and the material sorting device 100 according to the above embodiment, which is provided with a blowing assembly 20 and an ejection assembly 30. The detection mechanism 220, the blowing assembly 20, and the ejection assembly 30 are electrically connected to a control module (not shown). The control module is configured to receive material information transmitted by the detection mechanism 220 and control the blowing assembly 20 and / or the ejection assembly 30 to perform material sorting operations according to preset material sorting rules.

[0169] As shown in Figures 11, 25, and 26, the material sorting machine 200 is mainly used to sort and recycle different types of materials, such as ores. For example, the material sorting machine 200 can distinguish the quality of the materials based on the density and / or color of the materials and implement classified recycling of materials of different qualities to obtain two or more materials of high and low grades. For another example, the material sorting machine 200 can distinguish the types of materials based on the density, color, and / or composition (e.g., atoms) of the materials and implement classified recycling of different types of materials to obtain two or more materials.

[0170] The material sorting machine 200 includes a conveying mechanism 210, a detection mechanism 220 arranged above the conveying mechanism 210, a material sorting device 100 arranged below the conveying mechanism 210, and a recovery mechanism 230 arranged below the material sorting device 100, as well as a control mechanism 260 connected to the detection mechanism 220, the blowing assembly 20 and the pushing assembly 30.

[0171] The conveying mechanism 210 can be optionally a belt conveyor or a vibrating feeder, etc., which is mainly used to convey and release materials, and when released, causes the materials (such as copper ore 200a and iron ore 200b) to move along a preset first motion trajectory a and pass through the material sorting device 100 and the recovery mechanism 230 in sequence.

[0172] Detection mechanism 220 includes a camera and / or an X-ray detection component, primarily used to detect material size and classification parameters. The X-ray detection component can detect material size, density, and atomic mass, with density and / or atomic mass reflecting the material's classification and optionally serving as classification parameters. The camera can detect material shape, size, and color, with color reflecting the material's classification and optionally serving as classification parameters. For example, if detection mechanism 220 includes a camera, the camera can capture images of passing materials, enabling control mechanism 260 to identify the material's size and classification using image recognition technology based on the captured images.

[0173] It should be noted that, in addition to being disposed above the conveying mechanism 210 and detecting the material being conveyed, the detection mechanism 220 of this embodiment can also be disposed between the conveying mechanism 210 and the material sorting device 100 and detect the material after release.

[0174] The material sorting device 100 includes a blowing assembly 20 for changing the track of materials whose particle size (for example, the maximum particle size) falls within a first threshold value (such as 40mm-250mm), and a pushing assembly 30 for changing the track of materials whose particle size falls within a second threshold value (such as 251mm-600mm), wherein the upper limit value of the first threshold value is less than or equal to the lower limit value of the second threshold value. As a preferred example, the material sorting device 100 also includes a rear guard 61 and a second bracket 32, the blowing assembly 20 is at least partially mounted on the rear guard 61, and the pushing assembly 30 is mounted on the second bracket 32. Among them, the rear guard 61 and the second bracket 32 ​​are arranged in a direction away from the conveying mechanism 210 in sequence, ensuring that the blowing assembly 20 is closer to the conveying mechanism 210 than the pushing assembly 30, so that the material can pass over the blowing assembly 20 and the pushing assembly 30 in sequence, thereby effectively reducing the interference generated by the blowing assembly 20 and the pushing assembly 30 during operation. At the same time, the use of the rear protective member 61 and the second bracket 32 ​​to sequentially and independently support the blowing assembly 20 and the pushing assembly 30 can reduce the adverse effects of the vibration generated by the pushing assembly 30 on the operation of the blowing assembly 20.

[0175] The recovery mechanism 230 may include multiple recovery zones. In some embodiments, the recovery mechanism includes a first recovery zone 231 and a second recovery zone 232. Horizontally, the first recovery zone 231 is closer to the conveying mechanism 210 than the second recovery zone 232. The first recovery zone 231 is used to recover materials (e.g., copper ore 200a) released from the conveying mechanism 210 that have not been redirected by the blowing assembly 20 and the ejecting assembly 30, while the second recovery zone 232 is used to recover materials (e.g., iron ore 200b) released from the conveying mechanism 210 that have been redirected by the blowing assembly 20 or the ejecting assembly 30. As an example, each recovery zone may be a trough or hopper structure, etc.

[0176] The control mechanism 260 can control the blowing assembly 20 and the pushing assembly 30 based on the detection results of the detection mechanism 220, so that the blowing assembly 20 and the pushing assembly 30 can selectively change the path of the passing materials, thereby ensuring that different types of materials can be separately dropped into the first recovery area 231 and the second recovery area 232. As an optional example, the control mechanism 260 is also connected to the conveying mechanism 210 so that it can also control the operating status of the conveying mechanism 210.

[0177] In terms of specific implementation methods, the control mechanism 260 can be implemented in various appropriate ways. For example, the control mechanism 260 can include a control product implemented by a general-purpose processor ("CPU") and / or a dedicated processor. In some scenarios, the control mechanism 260 of the present disclosure can also be implemented by a programmable logic controller (PLC). Therefore, the present disclosure does not impose any restrictions on the specific implementation methods of the control mechanism 260, and those skilled in the art can implement it in a reasonable manner as needed based on the teachings of the present disclosure, and these methods still fall within the scope of protection of the present disclosure.

[0178] Next, the operating principle of the material sorting machine 200 will be described using the separation of copper ore 200a and iron ore 200b as an example. During operation, bulk material containing copper ore 200a and iron ore 200b is added to the conveying mechanism 210. The copper ore 200a and iron ore 200b can be transported by the conveying mechanism 210 and move along a first motion trajectory a when they are separated from the conveying mechanism 210. While the copper ore 200a and iron ore 200b are being transported by the conveying mechanism 210, the control mechanism 260 can detect their size and category parameters using the detection mechanism 220 and determine whether the ore is copper ore 200a or iron ore 200b based on the ore category parameters. If the detected ore is copper ore 200a, the control mechanism 260 does not activate the material sorting device 100, and the copper ore 200a continues to move along the first motion trajectory a and falls into the first recovery area 231 of the recovery mechanism 230. When the ore being detected is iron ore 200b, the control mechanism 260 determines whether the iron ore 200b is large or small based on the size of the ore. If it is small (i.e., the particle size falls within the first threshold), the blowing assembly 20 is immediately started when the iron ore 200b arrives at the area where the material sorting device 100 is located, so as to use the blowing assembly 20 to transfer the small iron ore 200b moving along the first motion trajectory a to the second motion trajectory b, and to make the iron ore 200b continue to move along the second motion trajectory b. It moves and eventually falls into the second recovery area 232 of the recovery mechanism 230; if it is large-particle iron ore 200b (i.e., the particle size falls within the second threshold), the pushing assembly 30 is immediately started when the iron ore 200b arrives at the area where the material sorting device 100 is located, so as to utilize the pushing assembly 30 to transfer the large-particle iron ore 200b moving along the first motion trajectory a to the third motion trajectory c, and make the iron ore 200b continue to move along the third motion trajectory c and eventually fall into the second recovery area 232 of the recovery mechanism 230.

[0179] Based on this, those skilled in the art can understand that, when practicing the present disclosure, the applicant innovatively integrated the blowing assembly 20 and the pushing assembly 30 into the material sorting device 100 of the material sorting machine 200, so that the control mechanism 260 of the material sorting machine 200 can not only control the material sorting device 100 to selectively change the track of the ore released by the conveying mechanism 210 based on the type of ore, so that the two types of ore produce different motion trajectories and fall into different recovery areas of the recovery mechanism 230 respectively, thereby realizing ore sorting, but also can use the blowing assembly 20 to change the track of small-particle ore or use the pushing assembly 30 to change the track of large-particle ore based on the size of the ore when the material sorting device 100 is enabled, thereby ensuring that the material sorting machine can have the respective advantages of the blowing assembly 20 and the pushing assembly 30, so as to implement low-power, high-efficiency and high-precision sorting of ores with a wider range of particle sizes (such as 40mm-600mm).
