Description

Technical Field

[0001] This disclosure generally relates to the field of mining technology. More specifically, this disclosure relates to a material feeding and separating mechanism and a sorting machine. Background Technology

[0002] In existing free-fall ore sorting devices, a common approach is to use a conveyor with an arc-shaped end. This allows material leaving the arc-shaped end to be ejected radially outward from that end, enabling the installation of more sorting actuators for further processing. In this design, the separating devices for different ore sizes also need to be arc-shaped. When the particle size of the ore changes, the boundary lines of the falling areas for different sizes may shift. Fixed separating plates are difficult to adjust appropriately to these changes. Using multiple separating plates of different sizes increases equipment costs and necessitates frequent plate replacements based on production conditions, resulting in wasted time and labor.

[0003] In view of this, there is an urgent need to provide a material discharge separation mechanism so as to achieve good separation of two sorting channels with simple operation. Utility Model Content

[0029] The specific embodiments disclosed herein will now be described in detail with reference to the accompanying drawings.

[0030] In this document, for ease of description and understanding, the transport direction of the transport device is defined as a first direction, and the direction perpendicular to the first direction on the horizontal plane is defined as a second direction. Those skilled in the art will understand that the above definitions are merely illustrative descriptions of the relative positions between components and do not constitute restrictive provisions regarding the specific positions and orientations of the various components in this disclosure.

[0031] Figure 1 An exemplary scenario in which embodiments of this disclosure can be applied is illustrated. In a conventional sorting apparatus 900, for example, for mineral sorting, it is typically necessary to classify the mineral 90 according to the type of particles. Specifically, for example, a transport device 910, such as a conveyor belt, can be used to transport the mineral along a first direction, and a device such as a vision inspection device 980 can be used to classify the mineral 90 on the transport device 910 according to its type. After the mineral 90 is transferred to the end of the transport device 910, the mineral 90 can be thrown out by inertia along the first direction and fall along a parabola. A sorting execution device 920, such as a pusher plate or an air jet device, can be provided on the lower side of the transport device 910. This sorting execution device 920 pushes a portion of the falling mineral 90 in the horizontal direction according to the classification result of the vision inspection device 980, causing it to fall along a modified parabolic curve. Thus, the sorting apparatus can divide the falling mineral into two parts that fall along a first parabolic curve 11 and a second parabolic curve 12, respectively, according to the type of mineral. By setting the first channel 101 and the second channel 102 in the landing area of ​​the first parabolic curve 11 and the second parabolic curve 12, the material sorting can be completed.

[0032] In such Figure 1In some existing technologies, a separator 930 is required at the boundary between the inlet of the first channel 101 and the inlet of the second channel 102 to ensure that materials falling into the first channel 101 and the second channel 102 can be well separated to improve sorting accuracy. In existing sorting devices 900, the end 911 of the conveying device 910 used to throw the ore 90 may be formed in an arc shape, semi-circular shape, or other non-linear structure to increase the space for the sorting execution device 920 and enhance the sorting capacity. In this case, the shape of the separator 930 also needs to correspond to the shape of the end 911 of the conveying device 910, that is, it should also be a non-linear shape.

[0033] See also Figure 2 , Figure 2 A schematic diagram illustrating the principle of adjusting the position of an existing material feeding separator is shown. In actual use, because the particle size of the ore 90 or the speed of the conveying device 910 may sometimes change, it may be necessary to adjust the inlet sizes of the first channel 101 and the second channel 102. At this time, in the existing... Figure 1 In this design, the partition plate 930 abuts against side baffles 940 fixed to the sides of the conveying device 910 on both sides. The size of the inlets of the first channel 101 and the second channel 102 is typically adjusted by moving the partition plate 930 directly along the side baffles 940. However, in reality, when the particle size of the material or the speed of the conveying device changes, the actual boundary line between the inlets of the first channel 101 and the second channel 102 expands or shrinks equidistantly with respect to the end 911 of the conveying device 910 as its center. That is, the diameter of this boundary line changes accordingly when the particle size of the material changes.

[0034] However, simply adjusting the distance between the separator 930 and the conveying device 910 will cause the adjusted separator 930 to be unable to adapt to the changed boundary line. For example, when the particle size changes and the first channel 101 and the second channel 102 form an ideal boundary line 901 with an increased diameter, if the separator 930 is simply shifted to the changed adjusted position 931, an error region a will be created between the adjusted position 931 and the ideal boundary line 901 due to the difference in diameter. This will cause the ore 90 that should actually fall into the first channel 101 to fall into the error region a and enter the second channel, resulting in a decrease in sorting accuracy. Furthermore, manufacturing multiple separators with different diameters is not only time-consuming to replace and increases costs, but also does not allow for stepless adjustment.

[0035] In view of this, the present disclosure provides a material feeding and separating mechanism, which, by setting a plate that can extend and bend at the same time, and a limiting device connected to the plate and limiting the plate relative to the material feeding and conveying device, can steplessly adjust the diameter, adapt to different working conditions, avoid the generation of gaps, and improve the sorting accuracy.

[0036] See also Figure 3 and Figure 4 , Figure 3 An exemplary perspective view of a material feeding separator mechanism according to some embodiments of this disclosure is shown; Figure 4 An exemplary top view of a material discharge separation mechanism according to some embodiments of this disclosure is shown. In some embodiments, the material discharge separation mechanism 100 includes a material discharge sorting device and a baffle mechanism. The material discharge sorting device includes a conveying device 110 such as a belt conveyor, and a sorting execution mechanism 120 such as a jetting assembly. The material discharge sorting device conveys the ore along a first direction via the conveying device 110 and throws the ore out at the end 111 of the conveying device 110. At the same time, the sorting execution mechanism 120 causes the ore of different specifications to fall along two different parabolic curves, thereby causing the ore of different specifications to be thrown into two different sorting channels respectively. The baffle mechanism includes an adjusting component 132 and a telescopic baffle 131. The adjusting component 132 is configured to be movable relative to the material discharge sorting device, and the telescopic baffle 131 is configured to be retractable relative to the adjusting component 132. The telescopic baffle 131 of the baffle mechanism is also flexible and deformable. By placing the telescopic baffle 131 between the two different sorting channels, materials of different specifications can be separated.

[0037] Specifically, the material discharge separation mechanism includes a processing platform 150 and a conveying device 110 disposed on the processing platform 150 for conveying materials. The conveying device 110 includes a conveyor belt 1101 and a conveying limiter 1102. The conveying limiter 1102 is disposed at the end 111 of the conveying device 110, and the conveyor belt 1101 covers the outside of the conveying limiter 1102. The conveying limiter 1102 protrudes in a first direction toward the side of the end 111 of the conveying device 110 from which the material is discharged. The protruding portion is formed in an arc shape to define the shape of the conveyor belt 1101 at the end 111 as arc-shaped. Thus, when the material moves on the conveyor belt 1101 to the end 111 of the conveying device 110, it can fall along the arc-shaped edge of the end 111 of the conveying device 110, and under the action of the sorting execution mechanism 120, the material falls into two approximately fan-shaped areas according to the two parabolic curves of its fall. The two roughly fan-shaped areas correspond to the entrances of the first channel 101, which is relatively close to the end 111 of the conveying device 110, and the entrances of the second channel 102, which is relatively far from the end 111 of the conveying device 110. The first channel 101 and the second channel 102 are two openings on the processing platform 150, each used to collect two different sizes of materials. A telescopic baffle 131 can be positioned between the first channel 101 and the second channel 102 to separate them and prevent mixing of different sizes of mineral materials.

[0038] Simultaneously, two outer baffles 140 can be provided on both sides of the end 111 of the conveying device along the second direction, and these two outer baffles 140 are arranged parallel to the first direction. The arrangement of the outer baffles 140 can correspond to the lateral boundary lines of the entrance areas of the first channel 101 and the second channel 102 when the material falls. Thus, the outer baffles 140 can be used to block the ore material thrown or splashed towards the lateral boundary lines of the first channel 101 or the second channel 102, preventing material loss during the sorting process. At the same time, the adjusting component 132 can be arranged adjacent to the inner wall of one outer baffle 140, and one end of the telescopic baffle 131 extending out of the adjusting component 132 is adjacent to the outer baffle 140. Meanwhile, the other end of the extended portion of the telescopic baffle 131 can extend to be adjacent to the inner wall of the other outer baffle 140. Thus, the two outer baffles 140 and the telescopic baffle 131 together enclose the area corresponding to the entrance of the first channel 101, thereby separating the first channel 101 and the second channel 102 more completely and thoroughly, and preventing the splashing and leakage of ore.

[0039] The processing platform 150 is provided with multiple positioning guide rails 151 extending radially from the end 111 of the conveying device 110 as the center. The baffle mechanism also includes a fixing member 1321, which is fixedly disposed at the protruding end of the telescopic baffle 131 and is adjustablely connected to one of the positioning guide rails 151. The adjusting component 132 of the baffle mechanism is disposed vertically below one side of the end 111 of the conveying device 110 along a second direction. The adjusting component 132 includes a first adjusting member 1322 and a second adjusting member 1323. The fixing member 1321, the first adjusting member 1322, and the second adjusting member 1323 are all generally rod-shaped. The first adjusting member 1322 and the second adjusting member 1323 are disposed adjacent to each other, and the gap between the first adjusting member 1322 and the second adjusting member 1323 is used for the telescopic baffle 131 to pass through. The first adjusting member 1322 is fixedly connected to the fixed end of the telescopic baffle 131, and the non-extended portion of the telescopic baffle 131 can be rolled up around the outer periphery of the first adjusting member 1322. The second adjusting member 1323 abuts against the telescopic baffle 131 from the other side relative to the first adjusting member 1322, and the position of the second adjusting member 1323 is adjustablely connected to a positioning guide rail 151. By adjusting the position of the second adjusting member 1323, the bending radius of the telescopic baffle 131 can be adjusted, and the telescopic baffle can also abut against the outer baffle 140.

[0040] The adjustment component 132 is disposed on one side of the dividing line between the first channel 101 and the second channel 102 along the second direction. One end of the telescopic baffle 131 extends out between the first adjustment member 1322 and the second adjustment member 1323 and can extend along the dividing line. The telescopic baffle 131 can bend along the trajectory of the dividing line to physically separate the entrance areas of the first channel 101 and the second channel 102 corresponding to two different types of minerals at the dividing line.

[0041] The material unloading separation mechanism also includes a limiting device for adjusting and defining the shape of the telescopic baffle 131. The limiting device includes at least one limiting part 161, which is positionally adjustable relative to the material unloading sorting device to abut against the telescopic baffle 131 and limit its position relative to the material unloading sorting device. Specifically, the limiting part 161 is rod-shaped, standing vertically, and its lower end is movably connected to the positioning guide rail 151 of the processing platform 150 via a snap-fit ​​connection or similar means. The radial sides of the multiple limiting parts 161 can abut against the telescopic baffle 131 to limit its position and shape by applying a pushing force to the telescopic baffle 131. For example, when the end 111 of the conveying device 110 is a regular arc shape, the multiple positioning guide rails 151 on the processing platform 150 can be arranged radially around the center of the arc, and the multiple limiting parts 161 are all adjusted to be at the same distance from the center on the horizontal plane. Thus, the telescopic baffle 131, which is abutted by the multiple limiting parts 161, can also be limited to a regular arc shape. Furthermore, by setting the distance between the multiple limiting parts 161 and the aforementioned second adjusting member 1323 and the aforementioned center, the radius of the arc-shaped structure of the telescopic baffle 131 can be controlled, thereby adjusting the protruding portion of the telescopic baffle 131 to be aligned with the actual position of the boundary line between the first channel 101 and the second channel 102.

[0042] The telescopic baffle 131 of the partition mechanism is a spring steel plate that can elastically deform relative to its telescopic direction. It has a certain curvature in its natural form and can elastically deform under the action of external force. Thus, the telescopic baffle 131 can naturally form an arc after being extended by the adjusting component 132, thereby facilitating adjustment to align with the shape of the end 111 of the conveying device 110.

[0043] See Figure 5 , Figure 5 An exemplary perspective view of a material feeding separation mechanism according to some embodiments of this disclosure is shown. The telescopic baffle 131 has a natural curvature bending towards the end 111 of the conveying device 110. Correspondingly, a limiting portion 161 is disposed on the side of the telescopic baffle 131 facing the end 111 of the conveying device 110, abutting against and limiting the telescopic baffle 131 in a direction away from the end 111 of the conveying device 110. A roller 152 is also provided on the radially outer peripheral surface of the limiting portion 161. The roller 152 can rotate about the limiting portion 161 as an axis, and its radially outer surface is used to abut against the surface of the telescopic baffle 131. Therefore, when adjusting the position of the telescopic baffle 131 and / or the limiting portion 161, no sliding friction occurs between them. Instead, they roll relative to each other using the roller 152, thereby reducing the occurrence of adverse conditions such as wear and jamming of both the limiting portion 161 and the telescopic baffle 131 due to friction.

[0044] See Figure 5 The baffle mechanism may also include a baffle drive mechanism 133, which includes a rotary drive device such as a motor. The fixed part 1331 of the rotary drive device is fixed to the processing platform 150, while the output part 1332 of the rotary drive device is driven to be connected to the fixing member 1321. Thus, during the adjustment process, the telescopic baffle 131 can be automatically extended or retracted by the baffle drive mechanism 133, saving manpower while ensuring a stable and uniform adjustment force, which is beneficial for fine adjustment.

[0045] Those skilled in the art will understand that while the above description presents an embodiment using an elastically deformable plate as a telescopic baffle, this disclosure does not limit this aspect. For example, the telescopic baffle can be configured as comprising multiple small rigid plates hinged sequentially in a chain-like manner, so that the baffle can bend along the aforementioned dividing line as a whole, while also possessing high structural strength and high hardness in the vertical direction, thereby reducing wear and deformation caused by the ore impacting the telescopic baffle. Furthermore, although the above description presents a scheme where the end of the conveying device has a regular arc-shaped structure, in some other embodiments, the end of the conveying device can also be configured as other irregular arc shapes, etc. In this case, it is only necessary to adjust the shape of the telescopic baffle to match the shape of the end of the conveying device by means of a limiting part. In some other embodiments, the processing platform may not be provided with positioning guide rails, but instead with multiple rows of threaded holes arranged radially around the end of the conveying device, so that the fixing member, the second adjusting member, and the multiple limiting parts can adjust the position and shape of the telescopic baffle by selectively connecting to the threaded holes at corresponding positions.

[0046] According to the embodiments disclosed herein, the unloading separation mechanism can achieve good separation of the two sorting channels with simple operation by setting a retractable and flexible telescopic baffle between the two sorting channels corresponding to the unloading sorting device, without the need to prepare baffles of various specifications, thus reducing production costs and adjustment time.

[0047] See Figure 6 , Figure 6 An exemplary side view of a sorting machine according to some embodiments of this disclosure is shown. In some embodiments, the sorting machine 200 may include a material discharge separation mechanism 100 and a frame 300 as described in the embodiments of this disclosure. The material discharge separation mechanism 100 is fixedly disposed on the upper side of the frame 300, and the frame 300 is provided with a first receiving part 301 and a second receiving part 302 corresponding to the first channel 101 and the second channel 102, the first receiving part 301 and the second receiving part 302 being used to receive the material sorted by the material discharge separation mechanism 100.
