Description

Technical Field

[0001] The present disclosure relates to the field of material sorting equipment, and particularly to a feeder and a sorting equipment. Background Art

[0002] A sorting equipment generally includes a conveying device for conveying materials, and an identification mechanism disposed above or downstream of the conveying device to identify the materials and perform sorting according to the identification results. In order to improve production capacity, it is necessary to increase the feeding amount. Correspondingly, it is also necessary to increase the recognition speed and accuracy, and ensure the sorting accuracy.

[0003] Since the feeding amount is increased, the materials are arranged more closely on the conveying device for conveying, making it difficult for the identification mechanism to perform image recognition, resulting in problems such as image segmentation errors and category errors; it is also difficult for the sorting mechanism to sort different categories of materials close to each other, resulting in sorting errors and other problems.

[0005] An exemplary embodiment of the first aspect of the present disclosure provides a feeder, including: a conveying device for conveying materials; a plurality of baffles disposed above the conveying device for guiding the materials conveyed by the conveying device to the discharging place of the conveying device so that the materials are separated from the conveying device at the discharging place; a blanking device disposed downstream of the conveying device, and a feeding surface for receiving the materials from the discharging place is formed on the upper side of the blanking device; wherein, the feeding surface is formed with a discharging edge and a receiving place, the discharging edge includes at least a section of arc or at least part of the sides of a regular polygon, the receiving place is correspondingly disposed with the discharging place and is used for receiving the materials from the discharging place, and the receiving place is located at the center of the arc of the discharging edge or the center of the regular polygon, so that the materials move from the receiving place to the discharging edge and are separated from the blanking device at the discharging edge.

[0006] In some embodiments, the blanking device is disposed on one side of the conveying device, and the receiving place is connected with the discharging place; or, the blanking device is disposed below the conveying device, and the receiving place is located below the discharging place for receiving the materials falling from the discharging place.

[0007] In some embodiments, the feeding surface is formed with a plurality of guiding mechanisms extending from the receiving place to the discharging edge, so that the materials are conveyed along the guiding mechanisms to the discharging edge and are separated from the blanking device.

[0008] In some embodiments, the baffle includes at least two blanking baffles, and the two blanking baffles are respectively located on both sides of the blanking position; the first end of the blanking baffle is adjacent to the blanking position, and the second end opposite to the first end is located upstream of the blanking position compared with the first end and is farther from the blanking position than the first end, so that the material conveyed on the conveying device moves on the conveying device towards the blanking position under the guidance of the blanking baffle and detaches from the conveying device at the blanking position.

[0009] In some embodiments, the baffle includes a first layer and a second layer, the second layer is disposed on the surface of the first layer facing the upstream side, and the hardness of the first layer is greater than that of the second layer.

[0010] In some embodiments, the baffle is a flat plate or an arc-shaped plate.

[0011] In some embodiments, the feeding surface is a flat surface as a whole, and is horizontally or obliquely arranged.

[0012] In some embodiments, the feeding surface is a conical surface, the top of the conical surface forms the material receiving position, and the bottom edge of the conical surface forms the discharging edge.

[0016] The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects: The material is guided by the baffle from the blanking position to the center of the blanking device, so that the material can be conveyed substantially radially from the center position of the feeding surface towards the circumferential side and thrown out from the discharging edge, thereby dispersing the material, and enabling the material to slide and be thrown out in a direction away from the material receiving position of the blanking device instead of all sliding in the same direction, which is more convenient for identification and sorting, improves the reliability of identification and the accuracy of sorting, and can further increase the conveying volume and sorting efficiency.

[0027] Specific embodiments of the present disclosure will be described below. It should be noted that in the specific description of these embodiments, for the sake of concise description, this specification cannot describe all features of the actual embodiments in detail. It should be understood that in the actual implementation of any embodiment, just as in the process of any engineering project or design project, various specific decisions are often made to achieve the specific goals of the developer and to meet system-related or business-related constraints, and this will also change from one embodiment to another. In addition, it can also be understood that although the efforts made in this development process may be complex and lengthy, for those of ordinary skill in the art related to the content disclosed in the present disclosure, some design, manufacturing, or production changes based on the technical content disclosed in the present disclosure are only conventional technical means and should not be understood as insufficient content of the present disclosure.

[0028] Unless otherwise defined, technical terms or scientific terms used in the claims and the specification shall have the ordinary meaning understood by those of ordinary skill in the art to which the present disclosure pertains. The terms "first", "second" and similar terms used in the specification and claims of the present patent application do not denote any order, quantity or importance, but are only used to distinguish different components. The terms "a" or "an" and the like do not denote a quantity limitation, but rather denote the presence of at least one. The terms "comprising" or "including" and the like are intended to mean that the elements or items appearing before "comprising" or "including" cover the elements or items listed after "comprising" or "including" and their equivalent elements, and do not exclude other elements or items. The terms "connected" or "coupled" and the like are not limited to physical or mechanical connections, nor are they limited to direct or indirect connections.

[0029] In the sorting field, such as ore sorting, waste sorting, agricultural product sorting, etc., the sorting device can be a device for sorting materials. For example, in ore sorting, the material can be a mixed material of coal and gangue, and the coal and gangue can be separately collected through the sorting device. The sorting device 100 can be as Figure 1As shown in the figure, it may include a feeder 110, an identification mechanism 120, and a sorting mechanism 130. The feeder 110 can be used to convey the materials to be sorted fed by the feeding mechanism. The identification mechanism 120 is used to detect the materials conveyed on the feeder 110 or thrown from downstream of the feeder 110, identify the categories of the materials, and determine whether the materials are the materials to be removed. The materials to be removed can be required materials, such as coal mines, etc., or non-required materials, such as gangue, etc. The sorting mechanism 130 is used to remove the materials to be removed. The sorting mechanism 130 is used to perform separation on the materials to be removed. For example, by hitting the materials in the air with a push plate or blowing air at the materials in the air through a nozzle, so that the materials to be removed deviate from the original movement trajectory and fall into the designated position of the collection device 140.

[0030] In some related technologies, as Figure 2 shown, the feeder 210 conveys materials downstream along the conveying direction. One end of the feeder 210 forms an arc-shaped edge 211 to expand the material dropping range. Correspondingly, the identification mechanism can also be formed into a corresponding arc to identify the materials falling along the arc-shaped edge 211, and the sorting mechanism is also arranged in a corresponding arc shape. However, in this solution, although the materials fall from different positions of the arc-shaped edge 211, their moving direction is still the same as the conveying direction of the conveying mechanism, that is, the materials are thrown along the conveying direction from different positions of the arc-shaped edge 211. Therefore, the interval distance of each material in the width direction of the feeder 210, that is, the direction perpendicular to the conveying direction, does not change. And, since the identification mechanism is generally an image acquisition device or an x-ray device, and it is arranged corresponding to the arc-shaped edge 211, this will cause the moving direction of the materials to form a certain angle with the acquisition direction of the identification mechanism, which will cause the material images to overlap in the images acquired by the identification mechanism, affecting image segmentation and recognition. And, it will also cause errors in the position judgment of the materials. On the other hand, it will also cause it to be difficult for the sorting mechanism to achieve precise sorting of the materials arranged compactly.

[0031] To solve the above problems, as Figure 3A 、 Figure 3B shown, the present disclosure provides a feeder 310, which may include a conveying device 311, a plurality of baffles 312, and a material dropping device 313. Among them, the conveying device 311 can be used to convey materials. The conveying device 311 can be a conveyor belt to convey materials through the conveyor belt; it can also be a slideway, a chute, etc., and the materials slide or roll on the surface of the slideway and chute to convey. The material of the slideway and chute can be metal or hard wear-resistant material.

[0032] A blanking area 3111 is formed on the conveying device 311, and the material conveyed on the conveying device 311 detaches from the conveying device 311 at the blanking area 3111. The feeder 310 may be provided with a plurality of baffles 312. The baffles 312 may be arranged above the conveying device 311 and are used to guide the material conveyed by the conveying device 311 to the blanking area 3111, so that the material detaches from the conveying device 311 at the blanking area 3111. The baffle 312 may be fixed above the conveying device 311 through a bracket (not shown in the figure). The lower edge may be in close proximity or clearance fit with the upper surface of the conveying device 311, such that the material conveyed on the conveying device 311 can change its direction by contacting the baffle 312, move towards the blanking area 3111, and detach from the conveying device 311 at the blanking area 3111. The baffle 312 may also be installed on the upper surface of the conveying device 311. For example, when the conveying device 311 is a chute or a trough, that is, the material is conveyed without using a conveyor belt, the baffle 312 installed on the upper surface is used to guide the material to the blanking area 3111.

[0033] The blanking device 313 may be arranged downstream of the conveying device 311. A feeding surface 3131 for receiving the material from the blanking area 3111 is formed on the upper side of the blanking device 313. Among them, the feeding surface 3131 is formed with a discharging edge 3132 and a material receiving area 3133. The discharging edge 3132 includes at least a part of an arc or at least a part of the side of a regular polygon. The discharging edge 3132 may extend by 90 degrees, 180 degrees or a larger angle, and the material detaches from the discharging edge 3132 of the blanking device 313. The discharging edge 3132 may also be formed as an annular discharging edge 3132, that is, the material may be discharged within a range of 360 degrees. The material receiving area 3133 is correspondingly arranged with the blanking area 3111 and is used to receive the material from the blanking area 3111, and the material receiving area 3133 is located at the center of the arc or the center of the regular polygon of the discharging edge 3132, so that the material moves from the material receiving area 3133 to the discharging edge 3132 and detaches from the discharging edge 3132 of the blanking device 313.

[0034] Through the feeder 310 disclosed in the present invention, the material can be guided by the baffle 312 and transported from the material drop point 3111 of the conveying device 311 to the material receiving point 3133 on the feeding surface 3131 of the material drop device 313, and the feeding surface 3131 is formed with a material discharge edge 3132 extending a certain arc span. Since the material receiving point 3133 is located at the center of the arc or the center of the regular polygon of the material discharge edge 3132, the material received by the material receiving point 3133 can move from the center position to the material discharge edge 3132, rather than moving to the material discharge edge 3132 and being thrown out along the conveying direction on the conveying device 311. In this way, the material is more dispersed, and the material can slide and be thrown out in the direction away from the material receiving point 3133 of the material drop device 313, rather than all sliding in the same direction, which is more convenient for identification and sorting, improves the reliability of identification and the accuracy of sorting, and can further improve the conveying volume and sorting efficiency.

[0035] In some embodiments, Figure 3A As shown, the discharge edge 3132a may be a circular arc, such as a semicircular arc; Figure 3B As shown, the discharge edge 3132b can also be a polyline composed of multiple regular polygonal sides that are in an arc shape as a whole. The polyline can be extended to form a similar arc of 180 degrees. The number of sides of the regular polygon can be 6-30 sides or more, and the number of sides of the corresponding polyline within the range of 180 degrees can be 3-15 or more sides. The more sides there are, the closer to the arc shape, and the fewer sides there are, the discharge edge 3132b is formed into multiple line segments with more obvious angles, and the corresponding identification device and sorting mechanism can also be formed into a corresponding multi-segment form. In this embodiment, the discharge edge 3132 can be located on one side of the blanking device 313, and the feeding surface 3131 can be tilted or formed with a certain curvature, so that the material is transported from the material receiving point 3133 (i.e., the center of the circle or the center of the polygon of the discharge edge 3132) toward the discharge edge 3132.

[0036] In some embodiments, Figure 4A As shown, the discharge edge 3132a can be a complete circle, or as shown in FIG. Figure 4B As shown, the discharge edge 3132b can be a complete edge of a regular polygon. In this embodiment, the discharge edge 3132 is formed on the complete circumference of the material receiving portion 3133, and the material receiving portion 3133 is located at the center of a circle or the center of a regular polygon. The material can be transported from the material receiving portion 3133 to the discharge edge 3132 in any direction and leave the blanking device 313 within a 360-degree range. Figure 5E , Figure 5FAs shown, the material dropping device 313 can be located below the conveying device 311. The identification mechanism and the sorting mechanism corresponding to the feeder 310 of this embodiment are also correspondingly formed into a complete ring or a similar ring connected by multiple lines, so that the materials thrown from the discharge edge 3132 can be classified, identified and sorted. The feeder 310 of this embodiment can drop materials from all directions, so the interval between materials can be maximized, and the material receiving capacity of the mechanism can also be maximized accordingly.

[0037] In some embodiments, the width of the drop 3111 can be set according to the width of the material. It needs to be set according to the maximum particle size of the material, and needs to be wider than the maximum particle size, which can be 1.5-2 times the width of the maximum particle size to avoid clogging.

[0038] In some embodiments, Figure 3A , Figure 3B , Figure 5A , Figure 5B , Figure 5C , Figure 5D , Figure 5E , Figure 6 , Figure 7 As shown, the drop point 3111 can be located at the end of the conveying direction of the conveying device 311 and at the center of the end. The conveying device 311 can include a conveyor belt, and the middle part of the conveying end of the conveyor belt can be formed as the drop point 3111. The conveying device 311 can be a slideway, and the material can move toward the end along the conveying direction through a vibrating slideway or an inclined slideway, and leave the conveying device 311 from the drop point 3111 formed in the middle of the end. In the embodiment of the present disclosure, a gap can be limited by two baffles 312 as the drop point 3111, and the material can pass through the gap and be transported from the end of the conveying device 311 to the drop point device 313, and the width of the gap is the width of the drop point 3111. A through slot can also be opened through a baffle 312, and the material can pass through the through slot and be transported from the end of the conveying device 311 to the drop point device 313, and the width of the through slot is the width of the drop point 3111. The top of the through slot can be open or have a certain height, and the height can basically exceed the height of all materials to avoid jamming.

[0039] In some embodiments, Figure 5F As shown, the material drop point 3111 can be located in the middle of the conveying device 311. The conveying device 311 can include multiple conveyor belts or slideways, which convey materials from the circumference to the middle, and a gap is formed in the middle as the material drop point 3111. The multiple conveyor belts or slideways on the circumference convey materials to the gap and the materials fall from the gap to the material drop device 313 below. Or as Figure 5FAs shown, a through hole is formed in the middle of the conveying device 311. Materials can move towards the through hole from one side or multiple sides of the conveying device 311. The conveying device 311 can be funnel-shaped, with the peripheral side higher than the middle, so that the materials can slide or roll towards the through hole in the middle and fall through the through hole to the material receiving place 3133. The diameter of the through hole can be set corresponding to the width of the material falling place 3111.

[0040] In some embodiments, such as Figure 3A , Figure 3B , Figure 5A , Figure 5B , Figure 6 , Figure 7 As shown, the blanking device 313 can be arranged on one side of the conveying device 311, and the material receiving place 3133 is connected to the material falling place 3111. In this embodiment, the material falling place 3111 can be located at the end of the conveying direction of the conveying device 311 and at the center of the end. One side of the blanking device 313 can be connected to the conveying device 311. Specifically, one end of the feeding surface 3131 can be smoothly connected to the conveying surface of the conveying device 311, and the opposite end of the feeding surface 3131 forms a discharging edge 3132. For example, the conveying surface of the conveying device 311 is a plane, and the feeding surface 3131 can also be a plane and serve as an extension of the conveying surface of the conveying device 311.

[0041] In some embodiments, the feeding surface 3131 can be a plane as a whole, arranged horizontally or obliquely. In the embodiments of the present disclosure, as Figure 5A shown, the feeding surface 3131 and the conveying surface can be a plane, which can be integrally formed or fixedly connected; the feeding surface 3131 can also be as Figure 5B , Figure 5C shown, at an angle with the conveying surface. For example, the feeding surface 3131 has a steeper angle, which can enable the materials to pass more quickly under the action of gravity compared to the conveying surface or slide more conveniently towards the discharging edge 3132.

[0042] In some other embodiments, such as Figure 5C , 5EAs shown in FIG. 5F, the material drop device 313 may be disposed below the conveying device 311, and the material receiving portion 3133 is located below the material drop portion 3111, for receiving the material dropped from the material drop portion 3111. In this embodiment, the material receiving portion 3133 of the feeding surface 3131 of the material drop device 313 may have a certain height difference with the material drop portion 3111 of the conveying device 311, and the material falls on the material receiving portion 3133 after falling a certain distance from the material drop portion 3111, and is further conveyed to the discharge edge 3132. In this embodiment, the discharge edge 3132 can be located on one side of the material receiving portion 3133, formed as a circular arc or a polyline of the edges of a regular polygon, and the discharge direction can be consistent with or inconsistent with the conveying direction of the conveying device 311. Since the blanking device 313 is located below the conveying device 311, the space can be used to make the discharge direction of the blanking device 313 opposite to the conveying direction of the conveying device 311 or form a certain angle, so that it can be conveniently used or combined with the structure and space design of the actual sorting equipment. Or, as Figure 4A , Figure 4B , Figure 5E , Figure 5F As shown, the discharge edge 3132 can also be formed on the complete circumferential side of the material connection point 3133, that is, formed as a complete edge of a circular arc or a regular polygon. By being arranged below the conveying device 311, spatial interference with the conveying device 311 is avoided. The blanking device 313 can be formed into a disc-shaped or umbrella-shaped structure. The material received at the material connection point 3133 can be conveyed to the circumferential side, thereby expanding the interval between the materials, facilitating subsequent identification and sorting, and can also further improve the identification reliability and sorting accuracy.

[0043] In some embodiments, Figure 6 As shown, the feeding surface 3131 may be formed with a plurality of guide mechanisms 3134 extending from the material connection point 3133 to the material discharge edge 3132, so that the material can be transported to the material discharge edge 3132 along the guide mechanisms 3134 and escape from the blanking device 313. In the embodiment of the present disclosure, a plurality of guide mechanisms 3134 may be formed on the feeding surface 3131 to further ensure the moving direction of the material, that is, to better realize that the material is basically transported in the direction of the center radius of the material discharge edge 3132 and escapes from the blanking device 313. The guide mechanism 3134 may be a guide rail protruding upward from the feeding surface 3131, or a groove sunken downward from the feeding surface 3131. Each guide mechanism 3134 may be a complete one extending from a position close to the material connection point 3133 to the material discharge edge 3132; or it may be a multi-segment structure arranged intermittently and in a collinear manner.

[0044] In some embodiments, Figure 3A , Figure 3B , Figure 6 , Figure 7As shown, the baffle 312 includes at least two blanking baffles 312a, and the two blanking baffles 312a can be respectively located on both sides of the blanking position 3111; the first end of the blanking baffle 312a is adjacent to the blanking position 3111, and the second end opposite to the first end is located upstream of the blanking position 3111 compared with the first end and the second end is farther from the blanking position 3111 than the first end, so that the material conveyed on the conveying device 311 moves towards the blanking position 3111 on the conveying device 311 under the guidance of the blanking baffle 312a and detaches from the conveying mechanism at the blanking position 3111. In this embodiment, at least two blanking baffles 312a can be included among the multiple baffles 312, which are respectively located on both sides of the blanking position 3111. The material moves driven by the conveying device 311. Through the guiding action of the two blanking baffles 312a, the material can smoothly detach from the conveying mechanism at the blanking position 3111, thereby ensuring that it can fall from the receiving position 3133 of the blanking device 313 onto the feeding surface 3131, so that the material can be dispersed and conveyed in multiple directions from the center of the discharge edge 3132.

[0045] In some embodiments, as Figure 8 shown, in addition to the two blanking baffles 312a, the multiple baffles 312 can further include a plurality of leading baffles 312b that realize guiding at different positions on the upper side of the conveying device 311. The multiple baffles 312 act together to guide the material to the blanking position 3111, ensuring the accuracy and reliability of the material guiding.

[0046] In some embodiments, the baffle 312 can be made of a metal material, such as iron; it can also be made of other materials with a certain hardness. The overall thickness can be 0.5 - 3 centimeters, for example, 1 centimeter thick.

[0047] In some embodiments, the baffle 312 can include a first layer and a second layer. The second layer is disposed on the surface of the first layer facing the upstream side, and the hardness of the first layer is greater than that of the second layer. In this embodiment, the first layer can be made of a metal material, such as iron; it can also be made of other materials with a certain hardness. The second layer can be a flexible material. Through the two - layer setting, the baffle 312 can have a certain rigid strength to provide a blocking force to the material, ensuring the accurate guiding of the material; and the surface in contact with the material, that is, the second layer, is made of a material with a lower hardness relative to the first layer, so as to avoid the collision of the material and also reduce the impact on the baffle 312, extending its service life.

[0048] In some embodiments, as Figure 3A 、 Figure 3B 、 Figure 6 shown, the baffle 312 can be a flat plate, and the material can move along one side of the baffle 312 to the blanking position 3111. In other embodiments, as Figure 7As described above, the baffle 312 can also be an arc-shaped plate, that is, the projection on the conveying surface of the conveying device 311 is arc-shaped. The arc-shaped plate can reduce the impact force of the material on the baffle 312.

[0049] In some embodiments, the feeding surface 3131 can be a conical surface. The top of the conical surface forms a material receiving place 3133, and the bottom edge of the conical surface forms a discharging edge 3132. In the embodiments of the present disclosure, the feeding surface 3131 can be formed as a conical surface. The top view can be as Figure 3A 、 Figure 3B or as Figure 4A 、 4B shown. The top view projection can be a partial or complete circle or regular polygon, and the whole is in the shape of a complete or incomplete umbrella, such as a conical surface with a circular or arc-shaped bottom edge, or a pyramid surface with a bottom edge corresponding to all or part of the edges of a regular polygon. As Figure 5D 、 Figure 5E 、 Figure 5F shown, the top of the conical surface forms a material receiving place 3133. There can be a certain drop between the top and the discharging edge 3132 at the bottom end, so that the material can slide down along the surface of the conical surface from the material receiving place 3133 under the action of gravity and be thrown out along each radial direction from the discharging edge 3132. Thus, the material can be better dispersed, and the material is not likely to be blocked.

[0050] In some embodiments, the intersection line of the conical surface and the vertical plane can be a combination of one or more of the following: a straight line segment or a concave curve. In the embodiments of the present disclosure, the conical surface can be a flat conical surface, that is, the intersection line of the conical surface and the vertical plane is a straight line segment, and the material can be conveyed and thrown out along the conical surface in a straight line. In other embodiments, the conical surface can be a curved surface with a radian, that is, the intersection line of the conical surface and the vertical plane can be a concave curve, such as a circular arc concave towards the inside of the cone corresponding to the conical surface, the brachistochrone curve, etc. In the case of using the brachistochrone curve, the block can fall from the material receiving place 3133 to the discharging edge 3132 and be thrown out fastest, which can accelerate the discharging speed.

[0051] In some embodiments, the feeder 310 may further include: a vibration mechanism for generating continuous or intermittent vibrations, which are formed on the conveying device 311 and / or the blanking device 313. In the embodiments of the present disclosure, the feeder 310 may be provided with a vibration mechanism, and the vibration mechanism may be connected to the conveying device 311. The conveying device 311 is a vibrating chute, and the materials are conveyed by using vibrations and the angle of the chute. The vibration mechanism may also be connected to the blanking device 313 to provide vibrations to the materials on the feeding surface 3131 of the blanking device 313, so that the materials on the blanking device 313 can be conveyed from the material receiving place 3133 to the discharging edge 3132 under the action of vibrations. The vibration mechanism may also be connected to the material discharging place 3111 of the conveying device 311 to provide vibrations to the material discharging place 3111. Since the width of the material discharging place 3111 is generally narrower than that of the conveying device 311, it is easy to cause material accumulation or blockage. By providing vibrations through the vibration mechanism, the mutual blockage of materials can be avoided or alleviated, making the material conveying smoother, ensuring the reliability of the feeder 310, and also improving the efficiency of the sorting machine.

[0052] In some embodiments, the feeder 310 may further include a material spreading mechanism (not shown in the figure), which can be used to apply a force to the materials conveyed to the material discharging place 3111. The material spreading mechanism may be arranged corresponding to the material discharging place 3111 and may be arranged below the material discharging place 3111. The materials conveyed to the material discharging place 3111 are pushed upward by a push rod or air is blown from the bottom upward to the materials conveyed to the material discharging place 3111, so that the materials conveyed to the material discharging place 3111 can be more smoothly separated from the conveying device 311, avoiding blockage at the material discharging place 3111, and can also dredge the blocked materials in case of blockage.

[0053] Based on the same inventive concept, the present disclosure also provides a sorting device, which may include: a feeder 310 as in any of the foregoing embodiments; an identification mechanism arranged downstream of the feeder 310 and corresponding to the discharging edge 3132 of the feeder 310 for identifying the categories of the materials separated from the discharging edge 3132; a sorting mechanism arranged downstream of the feeder 310 for sorting the materials based on the categories of the materials identified by the identification mechanism. The materials are guided by the baffle 312 from the material discharging place 3111 to the center of the blanking device 313, so that the materials can be conveyed from the center position of the feeding surface 3131 basically radially towards the periphery and are thrown out from the discharging edge 3132, thereby dispersing the materials and enabling the materials to slide and be thrown out in a direction away from the material receiving place 3133 of the blanking device 313 instead of all sliding in the same direction, which is more convenient for identification and sorting, improves the reliability of identification and the accuracy of sorting, and can further increase the conveying capacity and sorting efficiency.
