[0031] The exemplary embodiments of the disclosure provide an auxiliary device for parallel sorting of multiple sorting devices 200, as shown in Figure 1 , Figure 2 , which can include a top support 110, a bottom support 120 and a scraper conveyor 130.

[0032] The top layer support 110 is provided with a plurality of feeding ports for material falling. The top layer support 110 can be located at the upper part of the auxiliary device and arranged above the bottom layer support 120. The top layer support 110 can be a horizontally arranged plate with high strength and capable of supporting the scraper conveyor 130 and other equipment. The top layer support 110 can be provided with a plurality of vertical through holes as the feeding ports, so that the material falling at the scraper conveyor 130 can pass through the feeding ports and fall from the top layer support 110 to the bottom layer support 120.

[0033] The bottom layer support 120 is arranged below the top layer support 110 and used for supporting a plurality of sorting devices 200 side by side. The bottom layer support 120 can be located at the middle or lower part of the auxiliary device and below the top layer support 110. The bottom layer support 120 can be arranged in parallel with the top layer support 110 and be a horizontally arranged plate. The bottom layer support 120 can have high support strength, so as to support a plurality of sorting devices 200 installed side by side through the bottom layer support 120. The size of the bottom layer support 120 can be consistent with that of the top layer support 110. A staircase can be arranged between the top layer support 110 and the bottom layer support 120 for connecting the top layer support 110 and the bottom layer support 120. The relevant staff can go up to the top layer support 110 or the bottom layer support 120 through the staircase, so as to facilitate the maintenance and repair of the scraper conveyor 130 installed on the top layer support 110 and the plurality of sorting devices 200 installed on the bottom layer support 120. The sorting devices 200 installed on the bottom layer support 120 can be arranged corresponding to the feeding ports of the top layer support 110, so as to receive and sort the material falling from the feeding ports through the sorting devices 200.

[0034] The scraper conveyor 130 is arranged on the top layer support 110 and can include a middle trough 131 and a scraper chain 132. The scraper conveyor 130 can be installed on the top layer support 110 and used for conveying material. The material can fall from the scraper conveyor 130, pass through the feeding ports arranged on the top layer support 110, and enter the sorting devices 200 arranged on the bottom layer support 120.

[0035] The middle trough 131 is provided with a plurality of material leakage gaps 1311 corresponding to the feeding ports, for allowing the material to fall through the material leakage gaps 1311. The bottom of the middle trough 131 can be fixedly connected to the top layer support 110, so that the scraper conveyor 130 is installed on the top layer support 110, thereby avoiding the movement of the scraper conveyor 130 during operation, which causes the material to be stuck on the top layer support 110, and improving the running stability of the scraper conveyor 130. The middle trough 131 can be provided with a plurality of material leakage gaps 1311, which can be arranged side by side along the extension direction of the middle trough 131, so that the material leakage gaps 1311 on the middle trough 131 can be arranged corresponding to the feeding ports. The number of the material leakage gaps 1311 is consistent with the number of the feeding ports, so that the material leakage gaps 1311 and the feeding ports are one-to-one corresponding. The material can fall through the material leakage gaps 1311 and enter the sorting equipment 200 of the bottom layer support 120 through the feeding ports. The middle trough 131 can be made of high-strength steel plates or other plate materials, and the inside of the middle trough 131 can form a rectangular groove, so as to facilitate the installation of the scraper chain 132 and enable the scraper chain 132 to surround the middle trough 131. Among them, the material leakage gap 1311 located at the starting position of the scraper conveyor 130 can be set to a smaller size, so that the material can fall through the material leakage gap 1311, and the remaining material is conveyed to the subsequent other material leakage gaps 1311 by the scraper conveyor 130. The sizes of the plurality of material leakage gaps 1311 along the running direction of the scraper conveyor 130 can gradually increase from small to large, so that each material leakage gap 1311 has approximately equal amount of material falling down, thereby achieving uniform feeding of the plurality of sorting equipment 200. In some embodiments, the plurality of material leakage gaps 1311 can be arranged at different positions of the middle trough 131 in the width direction. Specifically, in the case of three material leakage gaps 1311, the first material leakage gap 1311 can be located at the left of the middle trough 131 in the width direction, the second material leakage gap 1311 can be located at the middle of the middle trough 131 in the width direction, and the third material leakage gap 1311 can be located at the right of the middle trough 131 in the width direction. This can disperse the plurality of material leakage gaps 1311 in the width direction and locate them at different width intervals of the middle trough 131, so that each sorting equipment 200 can accurately receive its corresponding material share.

[0036] The scraper chain 132 surrounds the middle trough 131 and is used for conveying the material. The scraper chain 132 can perform a circular motion around the middle trough 131, thereby moving the material along with the scraper chain 132 until the material moves to the material leakage gap 1311, and then falls through the material leakage gap 1311. As shown in FIG. 1, the scraper chain 132 is provided with a plurality of scraper plates 1321, which are arranged side by side along the extension direction of the scraper chain 132. The scraper plates 1321 are arranged in a staggered manner along the extension direction of the scraper chain 132, so that the material can be conveyed by the scraper chain 132 in a staggered manner. Figure 3As shown, the scraper chain 132 can include a chain and a plurality of scrapers. The chain can be arranged around the middle trough 131 in the direction of the extension of the middle trough 131, so that the chain can move in a circle around the middle trough 131. The scrapers can be flat plates, and the plurality of scrapers can be fixed to the chain, so that the middle of the scrapers is fixedly connected to the chain, and the scrapers can extend in the width direction of the middle trough 131. The scrapers can be fixedly connected to the chain by welding, bolting or clamping, etc. The length of the scrapers can be equal to the inner width of the middle trough 131, so that in the process of the chain moving in a circle around the middle trough 131, the scrapers move around the middle trough 131, thereby being able to drive the materials in the middle trough 131 to move along the middle trough 131 in the direction of the extension of the middle trough 131. In some embodiments, the scraper conveyor 130 can include a power assembly and a transmission assembly. The power assembly can be arranged at the tail of the scraper conveyor 130, and the scraper chain 132 can be driven to move around the middle trough 131 by the power assembly. The end of the scraper conveyor 130 away from the power assembly can be provided with a transmission assembly, and the transmission assembly can include a push-pull oil cylinder, which can pull the scraper chain 132 taut, thereby facilitating the movement of the scraper chain 132 around the middle trough 131.

[0037] The auxiliary device provided by the present disclosure can install multiple sorting devices 200 side by side to realize parallel sorting, and can ensure the conveying of materials and higher stability of the sorting process. The scraper conveyor 130 is installed on the top support 110, and the materials are conveyed through the scraper conveyor 130 and enter the sorting device 200 of the bottom support 120 through the feeding port of the top support 110. Different from the design of the current technology that the material conveying device and the sorting device 200 are installed on the same horizontal plane, the auxiliary device provided by the present disclosure can set the material conveying device and the sorting device 200 on different planes in the vertical direction, which can effectively reduce the floor area of the material conveying device and the sorting device 200 and save space. By setting multiple feeding ports on the top support 110, the materials conveyed by the scraper conveyor 130 can be distributed to the multiple sorting devices 200 installed on the bottom support 120, which can realize parallel sorting processing of multiple devices, improve the sorting efficiency, and greatly improve the output of material sorting. Through the middle groove 131 and the scraper chain 132 of the scraper conveyor 130, the conveying efficiency of the materials can be improved, and the residual and jamming of the materials can be avoided. By matching the material leakage gap 1311 of the scraper conveyor 130 with the feeding port of the top support 110, the accumulation and jamming of the materials can be avoided, and the materials can all fall into the sorting device 200 of the bottom support 120. By setting stairs on the auxiliary device, workers can easily enter the top support 110 or the bottom support 120 to regularly maintain the scraper conveyor 130 and the sorting device 200, which can reduce the maintenance difficulty and improve the maintenance efficiency. The auxiliary device provided by the present disclosure has the advantages of compact structure and convenient maintenance, and can be widely applied to garbage treatment, mineral processing and other scenes requiring parallel operation of the sorting device 200, which can significantly improve the efficiency and quality of material sorting and effectively reduce the operating cost.

[0038] In some embodiments, as Figure 3As shown, the middle trough 131 can include a bottom plate 133 slidingly arranged in the middle trough 131 and sliding along the width direction of the middle trough 131 to form the material leakage gap 1311. The bottom plate 133 of the middle trough 131 can slide along the width direction to form the material leakage gap 1311 for material falling in the middle trough 131. The bottom plate 133 can be slid to any position to obtain a material leakage gap 1311 of different sizes. After the position of the bottom plate 133 is set, the bottom plate 133 can be fixed by structures such as buckles, limit devices, etc., so that the bottom plate 133 can remain at the current position, and the bottom plate 133 is prevented from sliding to change the material leakage gap 1311 during the operation of the scraper conveyor 130, thereby ensuring the stability of the scraper conveyor 130 in the working state. In some embodiments, the middle trough 131 can be a detachable modular structure and can include a plurality of module troughs. The extension length of the middle trough 131 can be changed by installing and dismounting the module troughs according to the specific sorting yield requirement, thereby changing the length of the scraper conveyor 130 and adaptively adjusting the scraper conveyor 130. In addition, the number and position of the material leakage gap 1311 can also be changed by installing and dismounting the module troughs.

[0039] According to the embodiments of the present disclosure, the size of the material leakage gap 1311 of the scraper conveyor 130 can be controlled by the bottom plate 133 slidingly arranged in the middle trough 131, so that the amount of material fed by the scraper conveyor 130 to each sorting device 200 can be controlled. According to the embodiments, the falling amount of material can be accurately controlled, and the uniform distribution of material among the plurality of sorting devices 200 can be realized, thereby maximizing the working efficiency and sorting precision of the sorting device 200. The bottom plate 133 can be fixed at any position by the fixing structure, which prevents the bottom plate 133 from sliding during the conveying of the material by the scraper conveyor 130 and ensures the stability and reliability of the scraper conveyor 130. The detachable middle trough 131 structure can be used to simply and quickly adjust the scraper conveying device according to the sorting requirement, has better adaptability, and is convenient for maintenance and replacement.

[0040] In some embodiments, as Figure 3As shown, the scraper conveyor 130 may include a drive unit 134, connected to the base plate 133 and located on the side of the scraper conveyor 130, for moving the base plate 133 to change the size of the material leakage gap 1311 or to close the material leakage gap 1311. The drive unit 134 may be connected to one end of the base plate 133 along the width direction of the central trough 131 and is located on one side of the central trough 131. Rollers may be provided at the bottom of the drive unit 134, which can be driven by a motor or other power source to translate the drive unit 134 along the width direction of the central trough 131, thereby causing the base plate 133 to translate to different positions along the width direction of the central trough 131, thus changing the size of the material leakage gap 1311. Figure 3 As shown, the position of the base plate 133 can be changed by moving the drive device 134, thus placing the central trough 131 in different states. When the drive device 134 is at its furthest position from the central trough 131, the base plate 133 is in a fully open state, allowing the material leakage gap 1311 to open to its maximum size. The scraper chain 132 of the scraper conveyor 130 pushes the material to the fully open base plate 133, allowing all the material to fall through the material leakage gap 1311 formed by the fully open base plate 133. When the drive device 134 moves closer to one side of the central trough 131, the base plate 133 is in a wide-open state, allowing the material leakage gap 1311 to open slightly smaller than its maximum size. The size of the material leakage gap 1311 formed by the wide-open base plate 133 can be 60% to 80% of its maximum size. Correspondingly, the scraper chain 132 of the scraper conveyor 130 pushes the material to the open bottom plate 133, allowing some material to fall through the leakage gap 1311 formed by the open bottom plate 133. Approximately 60% to 80% of the material conveyed by the scraper conveyor 130 to the open bottom plate 133 falls through this leakage gap, effectively controlling the amount of material falling. When the drive unit 134 is closer to the central trough 131, the bottom plate 133 is in a smaller opening state, allowing the leakage gap 1311 to open to a smaller size. The size of the leakage gap 1311 corresponding to the smaller opening bottom plate 133 can be 20% to 40% of the maximum size. Correspondingly, the scraper chain 132 of the scraper conveyor 130 pushes the material to the slightly open bottom plate 133, allowing some material to fall through the leakage gap 1311 formed by the slightly open bottom plate 133. The material falling through the leakage gap 1311 formed by the slightly open bottom plate is approximately 20% to 40% of the material conveyed by the scraper conveyor 130 to the slightly open bottom plate 133, thereby effectively controlling the amount of material falling. The drive device 134 is located on the side of the central trough 131. When the distance to the central trough 131 is minimal, the bottom plate 133 is in a closed state, thereby closing the leakage gap 1311 and preventing material from falling through the central trough 131.

[0041] Through the embodiments of the present disclosure, the bottom plate 133 can be moved by the driving device 134, so that the size of the material leakage gap 1311 can be changed more flexibly, the adjustment of the bottom plate 133 from a full open state, a large open state, a small open state to a closed state can be realized, and the amount of material falling can be controlled by controlling the size of the material leakage gap 1311. In the case that a plurality of sorting devices 200 are arranged side by side in the auxiliary device, the size of the material leakage gap 1311 can be changed to control the amount of material fed to each sorting device 200. Moreover, according to the specifications of the sorting device 200, the bottom plate 133 can be moved by the driving device 134 to change the size of the material leakage gap 1311, so that the amount of material falling into the sorting device 200 is kept within the normal sorting amount of the sorting device 200, and the execution efficiency of the sorting device 200 is maximized. For the sorting device 200 that fails, the bottom plate 133 can be set to a closed state to avoid the situation of sorting error or unable to sort. In addition, through the embodiments of the present disclosure, a plurality of sorting devices 200 can be divided into several groups according to the sorting requirements, different operation time periods are set for each group of sorting devices 200, the bottom plate 133 is moved by the driving device 134 to change the size of the material leakage gap 1311, and the corresponding material leakage gap 1311 is opened according to the operation time period to fall material downward, so that the shift system operation of the multiple groups of sorting devices 200 is realized. The fatigue and failure of the sorting device 200 caused by long-time continuous operation can be effectively avoided, the sorting efficiency can be effectively improved, and the energy consumption of the sorting device 200 can be reduced.

[0042] In some embodiments, as Figure 1 , Figure 2As shown, the top layer support 110 can include a plurality of material leakage hoppers 111, each arranged below a feeding port and corresponding to the feeding port, for receiving the material falling from the material leakage gap 1311 and conveying to the corresponding sorting device 200. The top layer support 110 can be provided with a plurality of material leakage hoppers 111 fixedly arranged at the bottom of the top layer support 110. The material leakage hopper 111 can be in the shape of a funnel, and the upper cross-sectional dimension of the material leakage hopper 111 can be greater than the lower cross-sectional dimension of the material leakage hopper 111. The material leakage hopper 111 can be arranged below the feeding port, and the top of the material leakage hopper 111 can be matched with the feeding port or slightly larger than the size of the feeding port, so that the material can pass through the feeding port and enter the material leakage hopper 111, and then enter the sorting device 200 below the material leakage hopper 111. The top of the material leakage hopper 111 can be fixedly connected with the bottom surface of the top layer support 110, so that there is no gap between the material leakage hopper 111 and the top layer support 110, and the material is prevented from falling out of the gap. The top of the material leakage hopper 111 can be detachably connected with the bottom surface of the top layer support 110, so that the material leakage hopper 111 is tightly connected with the top layer support 110, and meanwhile, the material leakage hopper 111 can be easily disassembled and replaced. The sorting device 200 can be provided with a feeding port 251 at the top for the material to enter, and the bottom of the material leakage hopper 111 can be arranged corresponding to the feeding port 251, so that the size of the bottom of the material leakage hopper 111 matches the size of the feeding port 251. The size of the bottom of the material leakage hopper 111 can also be slightly smaller than the size of the feeding port 251, so as to ensure that the material can enter the sorting device 200 through the material leakage hopper 111, and avoid falling out of the sorting device 200 due to the gap between the material leakage hopper 111 and the sorting device 200. The bottom of the material leakage hopper 111 can be fixedly connected with the feeding port 251 at the top of the sorting device 200, so as to avoid the gap between the material leakage hopper 111 and the sorting device 200, and prevent the material from falling out. The bottom of the material leakage hopper 111 can also have a certain interval with the feeding port 251 at the top of the sorting device 200, so as to facilitate the installation and debugging of the sorting device 200. Through the plurality of material leakage hoppers 111 provided in the embodiment, the material falling from the material leakage gap 1311 can be accurately guided into the feeding port 251 of the sorting device 200, the scattering of the material is avoided, and the conveying efficiency is improved. Through the material leakage hopper 111, it can be ensured that the material enters the sorting device 200 through the material leakage hopper 111, and the leakage and waste of the material are avoided.

[0043] In some embodiments, as shown in Figure 1 、 Figure 2 The bottom layer support 120 can include a plurality of first discharge pipelines 121 and a plurality of second discharge pipelines 122.

[0044] A plurality of first discharge pipes 121 are arranged at the bottom of the bottom layer support 120. The first discharge pipes 121 are arranged one-to-one with the sorting devices 200, and are used to receive the first target materials sorted by the sorting devices 200. The bottom layer support 120 can be provided with a plurality of first discharge ports. The first discharge pipes 121 can be arranged in cooperation with the first discharge ports, so that the top of the first discharge pipes 121 is connected with the first discharge ports. The first discharge pipes 121 can be arranged according to the arrangement mode of the plurality of sorting devices 200, so that the plurality of first discharge pipes 121 are arranged side by side along the extension direction of the scraper conveyor 130. The sorting devices 200 can sort the materials received by the feed ports 251, so that the materials are separated into the first target materials and the second target materials. The materials can be ores, the first target materials sorted can be concentrates meeting the sorting conditions, and the second target materials can be tailings not meeting the sorting requirements. The first target materials can be discharged by the sorting devices 200, pass through the first discharge ports of the bottom layer support 120, and be discharged to the first discharge pipes 121 arranged below the bottom layer support 120, and then be conveyed to the subsequent related devices through the first discharge pipes 121. The first discharge ports can be arranged one-to-one with the sorting devices 200, so that the first target materials obtained by each sorting device 200 after sorting can enter the first discharge port corresponding to the sorting device 200. The first discharge pipes 121 can also be arranged one-to-one with the sorting devices 200, so that each first discharge pipe 121 can receive the first target materials obtained by the corresponding sorting device 200 after sorting. The first discharge pipes 121 can be arranged one-to-one in cooperation with the first discharge ports. The top of the first discharge pipes 121 can be fixedly connected with the bottom support, and the size of the top of the first discharge pipes 121 can be the same as the size of the first discharge ports, so that the first target materials can all enter the first discharge pipes 121, and material leakage can be avoided.

[0045] The plurality of second discharge pipes 122 are arranged at the bottom of the bottom layer support 120, and the second discharge pipes 122 are arranged one-to-one with the sorting devices 200, and are used to receive the second target materials sorted by the sorting devices 200. The bottom layer support 120 can be provided with a plurality of second discharge ports arranged side by side, and the second discharge ports can be arranged side by side with the first discharge ports. The second discharge pipes 122 can be arranged in cooperation with the second discharge ports, so that the top of the second discharge pipes 122 is connected with the second discharge ports. The second discharge pipes 122 can be arranged according to the arrangement mode of the plurality of sorting devices 200, so that the plurality of second discharge pipes 122 are arranged side by side along the extension direction of the scraper conveyor 130. The second target materials can be discharged from the sorting devices 200, discharged from the second discharge ports of the bottom layer support 120 to the second discharge pipes 122 arranged below the bottom layer support 120, and transported to the subsequent related devices through the second discharge pipes 122. The second discharge ports can be arranged one-to-one with the sorting devices 200, so that the second target materials obtained by each sorting device 200 after sorting can enter the second discharge port corresponding to the sorting device 200. The second discharge pipes 122 can also be arranged one-to-one with the sorting devices 200, so that each second discharge pipe 122 can receive the second target materials obtained by the corresponding sorting device 200 after sorting. The second discharge pipes 122 can be arranged one-to-one in cooperation with the second discharge ports. The top of the second discharge pipe 122 can be fixedly connected with the bottom support, and the size of the top of the second discharge pipe 122 can be the same as the size of the second discharge port, so that the second target materials can enter the second discharge pipe 122 completely, and material leakage can be avoided.

[0046] According to the embodiments of the present disclosure, different types of materials can be received by the first discharge pipe 121 and the second discharge pipe 122 respectively, the first target materials can enter the first discharge pipe 121, the second target materials can enter the second discharge pipe 122, the first target materials and the second target materials can be separated from each other, the separation and sorting of the materials can be realized, and the mixing of the materials can be effectively avoided. At the same time, all the materials corresponding to the first discharge pipe 121 and the second discharge pipe 122 can be received, the leakage of the materials can be effectively avoided, and the safety of sorting can be ensured.

[0047] In some embodiments, as shown in Figure 1 , Figure 2 The auxiliary device can further include a first conveying device 140 and a second conveying device 150.

[0048] The first conveying device 140 is arranged at the bottom of the first discharge pipeline 121 and is used to receive the first target material conveyed by each first discharge pipeline 121. The first conveying device 140 can be arranged only one and is arranged below the plurality of first discharge pipelines 121 arranged in parallel. The first target material conveyed by each first discharge pipeline 121 can all enter the first conveying device 140 and be conveyed to the subsequent processing and storage equipment by the first conveying device 140. The first conveying device 140 can be a conveying belt extending along the extending direction of the scraper conveyor 130. The width of the conveying belt can be greater than or equal to the diameter of the first discharge pipeline 121 to ensure that the material falling from the first discharge pipeline 121 all falls into the first conveying device 140. The first conveying device 140 can also be a plate conveyor. The plate conveyor can extend along the length direction of the scraper conveyor 130, is connected by a series of rigid slats connected into a chain, and moves along a fixed track. The first target material can fall onto the top surface of the rigid slat and move along the fixed track of the rigid slat. The first conveying device 140 can also be a vibrating conveyor. The vibrating motor or eccentric wheel and other structures can drive the groove of the vibrating conveyor to vibrate. The first target material falling into the groove of the vibrating conveyor vibrates along with the groove. The first target material moves along the extending direction of the groove due to the inertia caused by the vibration of the groove.

[0049] The second conveying device 150 is arranged at the bottom of the second discharge pipeline 122 and used for receiving the second target material conveyed by each second discharge pipeline 122. The second conveying device 150 can be arranged only one and arranged below the plurality of second discharge pipelines 122 arranged in parallel. The second target material conveyed by each second discharge pipeline 122 can all enter the second conveying device 150 and conveyed to the subsequent processing and storage equipment through the second conveying device 150. The first conveying device 140 and the second conveying device 150 can be the same equipment. The second conveying device 150 can be a conveying belt extending along the extending direction of the scraper conveyor 130. The width of the conveying belt can be greater than or equal to the diameter of the second discharge pipeline 122 to ensure that the material falling from the second discharge pipeline 122 all falls into the second conveying device 150. The second conveying device 150 can also be a plate conveyor. The plate conveyor can extend along the length direction of the scraper conveyor 130, connected by a series of rigid slats connected into a chain and moved along a fixed track. The second target material can fall onto the top surface of the rigid slat and move along with the fixed track of the rigid slat. The second conveying device 150 can also be a vibrating conveyor. The vibrating motor or eccentric wheel and the like structure can drive the vibration of the trough body of the vibrating conveyor. The second target material falling into the trough body of the vibrating conveyor vibrates along with the trough body. The second target material moves along the extending direction of the trough body due to the inertia caused by the vibration of the trough body. The first conveying device 140 and the second conveying device 150 can also be different equipment. The first conveying device 140 and the second conveying device 150 can be determined according to the conveying distance and the material conveyed. In the case of long-distance transmission, the conveying belt or the plate conveyor with high transmission efficiency can be selected as the first conveying device 140 or the second conveying device 150. In the case of short-distance transmission, the vibrating conveyor can be selected as the first conveying device 140 or the second conveying device 150. In the case of heavy material, the plate conveyor with strong carrying capacity can be selected as the first conveying device 140 or the second conveying device 150.

[0050] According to the embodiments of the present disclosure, the first target material conveyed by the first discharge pipeline 121 corresponding to each sorting equipment 200 can be received by the first conveying device 140, and the second target material conveyed by the second discharge pipeline 122 corresponding to each sorting equipment 200 can be received by the second conveying device 150. The first target material and the second target material can be received separately and transmitted to the subsequent storage or processing equipment respectively, so that the material can be conveyed in time and the timeliness of conveying the sorted material can be improved.

[0051] Based on the same inventive concept, like Figure 4As shown, the present disclosure also provides a sorting device 200, which is installed on the bottom support 120 of the auxiliary device according to any one of the preceding embodiments, and is used for sorting materials. The sorting device 200 can include a feeding conveying mechanism 210, an identification mechanism 220, and a sorting mechanism 230.

[0052] The feeding conveying mechanism 210 is located below the feeding port and is used for receiving the materials falling from the feeding port, so that the materials fall from the end of the feeding conveying mechanism 210. The feeding conveying mechanism 210 can be arranged below the feeding port, can receive the materials falling from the feeding port, and can spread the received materials smoothly and uniformly through the movement of the feeding mechanism, and then convey the materials to the subsequent identification mechanism 220 for identification. Since the material leakage hopper 111 can be arranged at the bottom of the top support 110, the materials falling from the feeding port can be received through the funnel-shaped structure with a large size at the top and a small size at the bottom, and then fall from the small size at the bottom. The feeding conveying mechanism 210 can be arranged below the material leakage hopper 111 to receive the materials falling from the material leakage hopper 111. Since the size of the bottom of the material leakage hopper 111 is small, the materials falling from the material leakage hopper 111 to the feeding conveying mechanism 210 can be blocked or overlapped, which makes it difficult for the subsequent identification mechanism 220 to identify. Therefore, the materials can be spread uniformly through the vibration of the feeding conveying mechanism 210 to avoid mutual blocking or overlapping. A material spreading device can also be arranged between the feeding conveying mechanism 210 and the feeding port, so that the materials falling from the feeding port can fall uniformly onto the feeding conveying mechanism 210 through the material spreading device. The feeding conveying mechanism 210 can convey the materials falling from the feeding port to the end of the feeding conveying mechanism 210 away from the feeding port, and then make the materials fall from the end of the feeding conveying mechanism 210 into the subsequent sorting process.

[0053] The identification mechanism 220 is used for identifying the type of the materials. The identification mechanism 220 can be a mechanism arranged downstream of the feeding conveying mechanism 210, and is used for identifying the type of the materials conveyed by the feeding conveying mechanism 210. The identification mechanism 220 can be arranged at the end of the feeding conveying mechanism 210 and spaced apart from the feeding conveying mechanism 210. The identification mechanism 220 can identify the materials on the feeding conveying mechanism 210, determine the type of the materials, and distinguish the materials into first target materials and second target materials. The identification mechanism 220 can be an infrared detection device, an X-ray detector, or the like. The identification mechanism 220 can also be arranged below the feeding conveying mechanism 210, can identify the materials falling from the end of the feeding conveying mechanism 210, and then determine the type of the materials for sorting.

[0054] The sorting mechanism 230 is used to sort the materials according to the type of the materials identified by the identification mechanism 220. The sorting mechanism 230 can perform a sorting operation to separate different types of materials from each other according to the type of the materials determined by the identification mechanism 220. When the identification mechanism 220 determines that the current material is the first target material, the sorting mechanism 230 can remain in a standby state, so that the first target material can remain in the original motion state after falling from the end of the feeding conveying mechanism 210 and fall into the first discharge pipeline 121. When the identification mechanism 220 determines that the current material is the second target material, the sorting mechanism 230 can be activated, so that the second target material changes the motion state after falling from the end of the feeding conveying mechanism 210, thereby being distinguished from the first target material and entering the second discharge pipeline 122. The sorting mechanism 230 can be a blowing mechanism, which is suitable for materials with small particles or small mass, can apply an external force to the materials by blowing gas to change the falling trajectory of the materials, thereby separating different types of materials. The sorting mechanism 230 can also be a push plate mechanism, which is suitable for materials with large particles or large mass, can apply an external force to the materials by flipping the push plate to hit the materials, so as to change the falling trajectory of the materials, thereby separating different types of materials. The sorting mechanism 230 can be arranged below the end of the feeding conveying mechanism 210, or arranged below the feeding conveying mechanism 210 and spaced apart from the end of the aggregate conveying mechanism, so as to sort the gas falling from the end of the feeding conveying mechanism 210.

[0055] The sorting device 200 provided by the embodiment can transport materials by the feeding mechanism and disperse the materials, so as to avoid identification errors caused by material shielding or overlapping in the subsequent process, thereby improving the accuracy of material identification. The identification mechanism 220 can accurately determine the type of each material, thereby ensuring the accuracy of material sorting. The sorting mechanism 230 can efficiently and accurately sort each material according to the result identified by the identification mechanism 220, thereby effectively improving the accuracy of sorting and improving the accuracy and reliability of the sorting device 200. In addition, the sorting device 200 provided by the embodiment can meet various different working conditions and has good versatility.

[0056] In some embodiments, the feeding conveying mechanism 210 can be a vibrating feeder. The vibrating feeder can drive the materials being conveyed on the top surface of the vibrating feeder by the vibration of the vibrating feeder, so as to disperse the materials and avoid the influence of mutual shielding or overlapping of the materials on the identification and sorting effects. The vibrating feeder can be arranged horizontally, so that the inclination angle of the vibrating feeder relative to the underlying support 120 is 0°, which can ensure the stability of the materials during the conveying process and avoid the uneven conveying speed caused by the sliding of part of the materials, thereby affecting the efficiency and accuracy of sorting. For example, Figure 4 Figure 5 ​As shown, the feeding conveying mechanism 210 can include a first frame 240, a first shell 250, a second frame 260, and a second shell 270.

[0057] The first frame 240 is used to mount the feeding conveying mechanism 210. The first frame 240 can be arranged on the outer circumferential side of the feeding conveying mechanism 210, and the bottom of the first frame 240 can be mounted on the bottom layer support 120. Since the feeding conveying mechanism 210 is a vibrating feeder, continuous vibration can affect the identification and sorting efficiency and accuracy of the identification mechanism 220 and the sorting mechanism 230. Therefore, it is necessary to mount the feeding conveying mechanism 210 through the first frame 240, so that the feeding conveying mechanism 210 and other related structures are independently mounted, the feeding conveying mechanism 210 is separately mounted from the identification mechanism 220 and the sorting mechanism 230, so as to isolate the vibration through the first frame 240, avoid the vibration of the feeding conveying mechanism 210 being transmitted to the sorting mechanism 230, and affect the sorting effect.

[0058] The first shell 250 is arranged outside the first frame 240, and the top is provided with a feeding port 251. The first shell 250 can be arranged outside the first frame 240, so that the feeding conveying mechanism 210 is arranged in the first shell 250, and the feeding conveying mechanism 210 in the first shell 250 is protected. The top of the first shell 250 can be provided with a feeding port 251, which can be used to receive the material falling from the feeding port, so that the material can enter the feeding conveying mechanism 210 in the first shell 250, and the material can be dispersed by the feeding conveying mechanism 210 and smoothly transmitted to the identification mechanism 220 and the sorting mechanism 230. The top of the first shell 250 can be connected or abutted with the bottom of the material leakage hopper 111 mounted on the top layer support 110, so that the material in the material leakage hopper 111 all enters the feeding conveying device in the first shell 250 through the feeding port 251, and the material leakage is avoided.

[0059] The second frame 260 is used to mount the identification mechanism 220 and the sorting mechanism 230. The second frame 260 can be arranged at the outer circumferential side of the identification mechanism 220 and the sorting mechanism 230, and the bottom of the second frame 260 can be mounted on the bottom layer support 120. The identification mechanism 220 and the sorting mechanism 230 can be mounted on the second frame 260, and each of the identification mechanism 220 and the sorting mechanism 230 is independently mounted with the feeding conveying mechanism 210 in the first frame 240. Through the second frame 260, an independent mounting module can be formed with the first frame 240, so that the vibration generated by the feeding conveying mechanism 210 can be effectively avoided from affecting the identification mechanism 220 and the sorting mechanism 230 in the second frame 260, and the identification mechanism 220 and the sorting mechanism 230 can be ensured to remain stable during operation to avoid the influence on the sorting effect caused by the vibration. Through the second frame 260, the stability of the identification mechanism 220 and the sorting mechanism 230 can be improved, the structure of the identification mechanism 220 and the sorting mechanism 230 can be prevented from being affected by the vibration, and the identification accuracy and the sorting effect can be ensured.

[0060] The second shell 270 covers the second frame 260, and the front end of the second shell 270 is flexibly connected with the rear end of the first shell 250. The second shell 270 can cover the outside of the second frame 260, and the feeding conveying mechanism 210 is arranged in the second shell 270 to protect the feeding conveying mechanism 210 inside the second shell 270. The front end of the second shell 270 can be connected with the rear end of the first shell 250, so that the inside of the second shell 270 and the first shell 250 are communicated, and the feeding conveying mechanism 210 can convey the materials to the identification mechanism 220 and the sorting mechanism 230 to finally complete the sorting of the materials. The end of the feeding conveying mechanism 210 is directed to the rear end of the first shell 250, and the front end of the second shell 270 is the end of the second shell 270 close to the end of the feeding conveying mechanism 210. Since the feeding conveying mechanism 210 vibrates, the vibration can be transmitted to the first shell 250 to cause the first shell 250 to also vibrate to a certain extent. To ensure the stability of the second shell 270 and the mechanisms inside the second shell 270, the second shell 270 and the first shell 250 can be flexibly connected. A plurality of springs can be arranged at the connection part between the second shell 270 and the first shell 250 to absorb the vibration of the feeding conveying mechanism 210 and the first shell 250. A rubber shock-absorbing block can also be arranged between the second shell 270 and the first shell 250 to achieve flexible connection, and the elasticity and damping performance of the rubber shock-absorbing block can be used to absorb the vibration of the feeding conveying mechanism 210 and the first shell 250. A flexible hinge can also be used to connect the second shell 270 and the first shell 250, so that the second shell 270 and the first shell 250 can have a certain relative movement. When the feeding conveying mechanism 210 and the first shell 250 vibrate, the second shell 270 and the identification mechanism 220 and the sorting mechanism 230 inside the second shell 270 remain in a stationary state.

[0061] Through the embodiment, the feeding conveying mechanism 210 can be installed through the first frame 240, and the identification mechanism 220 and the sorting mechanism 230 can be installed through the second frame 260, so that the feeding conveying mechanism 210 which vibrates is separated from the identification mechanism 220 and the sorting mechanism 230 which need to avoid vibration, and the vibration is effectively isolated, and the vibration of the feeding conveying mechanism 210 does not affect the identification and sorting accuracy of the identification mechanism 220 and the sorting mechanism 230. Through the first shell 250 and the second shell 270 arranged on the first frame 240 and the second frame 260 respectively, the protection effect can be effectively achieved, the external environmental factors can be prevented from affecting the internal structure of the sorting device 200, and the operation safety of the sorting device 200 is ensured. At the same time, through the first shell 250 and the second shell 270, the materials in the sorting device 200 can be isolated from the outside, and the materials are prevented from leaking to the outside to affect the material sorting amount. Through the flexible connection of the first shell 250 and the second shell 270, the vibration can also be effectively isolated, so as to ensure the safety of the identification mechanism 220 and the sorting mechanism 230, and ensure the identification and sorting accuracy and efficiency of the identification mechanism 220 and the sorting mechanism 230.

[0062] In some embodiments, the sorting device 200 can include: an ear, arranged on the top of the first shell 250 and the second shell 270, used for lifting the sorting device 200. The lifting lug is a lifting auxiliary device, which can lift the sorting device 200 by a crane or a hoist, etc. through the lifting lug, so as to facilitate the installation and replacement of the sorting device 200. At the same time, the balance and stability of the sorting device 200 during lifting can be maintained by arranging the lifting lug, so as to avoid the falling of the sorting device 200 due to tilting or shaking during lifting. In the existing sorting device 200, in order to ensure the stability during lifting, the lifting lug is generally arranged on the side of the sorting device 200. According to the embodiment of the present disclosure, the lifting lug can be arranged on the top of the first shell 250 and the top of the second shell 270, so that the side of the sorting device 200 has no outward protruding structure. In the case that a plurality of sorting devices 200 are installed on the bottom support 120 of the auxiliary device, by arranging the lifting lug on the top of the first shell 250 and the top of the second shell 270, the outward protruding structure of the sorting device 200 is reduced, so that the installation distance between the sorting devices 200 can be closer in the case of side-by-side installation, which effectively reduces the distance between the sorting devices 200, thereby saving space. Through the embodiment, by arranging the lifting lug on the top of the sorting device 200, the outward protruding structure of the sorting device 200 can be reduced or eliminated, so that the distance between adjacent sorting devices 200 can be effectively shortened in the case of parallel installation, thereby effectively saving space, and avoiding interference between the sorting devices 200, so that the sorting devices 200 have higher safety in the case of parallel installation. Through the lifting lug, the lifting of the sorting device 200 can also be efficiently and stably completed, which has higher safety.

[0063] In some embodiments, the sorting device 200 is provided with a side door through which a worker can enter the sorting device 200 to facilitate installation, maintenance and debugging. The side door can be a door for allowing a worker to enter during the production of the sorting device 200. The sorting device 200 can include a hinge provided on the inner side of the first housing 250 and / or the second housing 270 for fixing the side door, and a handle provided on the outer wall of the side door and recessed inwardly into the sorting device 200. The side door can be provided on the first housing 250, and the hinge for fixing the side door can be installed on the inner side of the first housing 250. Generally, the hinge of the side door is installed on the outer side of the first housing 250, and by this embodiment, the hinge can be installed on the inner side of the first housing 250, thereby reducing or eliminating the outward protruding structure of the outer periphery of the first housing 250, and in the case where multiple sorting devices 200 are installed on the bottom layer support 120 of the auxiliary device, the installation distance between the sorting devices 200 can be made closer. The side door can also be provided on the second housing 270, and the hinge for fixing the side door can be installed on the inner side of the second housing 270, thereby reducing or eliminating the outward protruding structure of the outer periphery of the first housing 250, and in the case where multiple sorting devices 200 are installed on the bottom layer support 120 of the auxiliary device, the distance between the sorting devices 200 can be effectively reduced. The side door can be provided with a handle for opening the door. For a conventional sorting device 200, the handle is generally provided as an outwardly protruding structure to facilitate the entry of a worker through the side door. According to this embodiment, the handle can be provided on the outer wall of the side door and recessed inwardly into the sorting device 200, so that the outer edge of the handle does not protrude beyond the plane of the side door, and the outwardly protruding structure of the outer periphery of the sorting device 200 can be reduced or eliminated, and in the case where multiple sorting devices 200 are installed side by side on the bottom layer support 120 of the auxiliary device, the distance between the sorting devices 200 can be effectively reduced, and the sorting devices 200 can be arranged more closely. By this embodiment, the outwardly protruding structure of the sorting device 200 can be reduced or eliminated, thereby effectively shortening the distance between adjacent sorting devices 200 in the case where the sorting devices 200 are installed side by side, thereby saving space, avoiding interference between the sorting devices 200, and providing higher safety in the case where multiple sorting devices 200 are installed side by side. By providing the side door, the sorting device 200 can also be facilitated for mechanism installation and maintenance during the production of the sorting device 200.

[0064] In some embodiments, the sorting device 200 can comprise a front access door arranged at the front end of the first housing 250, and / or a rear access door arranged at the rear end of the second housing 270, and / or a window arranged at the top or rear end of the second housing 270. Since multiple sorting devices 200 need to be arranged side by side on the auxiliary device, the distance between the sorting devices 200 is small, and the sorting devices 200 are arranged closely. For the side door arranged on the production device for manual entry installation or maintenance, in this case, the side door can not be opened. Therefore, the sorting device 200 can be provided with a front access door at the front end of the first housing 250, and in the case that multiple sorting devices 200 are arranged side by side on the auxiliary device, the worker can enter through the front access door at the front end of the first housing 250 of the sorting device 200 that needs to be maintained, so as to facilitate the maintenance. The sorting device 200 can also be provided with a rear access door at the rear end of the second housing 270, and in the case that multiple sorting devices 200 are arranged side by side on the auxiliary device, the worker can enter through the rear access door at the front end of the second housing 270 of the sorting device 200 that needs to be maintained, so as to facilitate the maintenance. In addition, the sorting device 200 can also be provided with a window for observing the internal structure and working condition of the sorting device 200, and the window can be arranged at the top or rear end of the second housing 270, so as to facilitate the worker to observe the material running state inside the sorting device 200 from the outside of the sorting device 200, and facilitate the test of the running state of the sorting device 200. Through the front access door, the rear access door and the window, the inspection and maintenance of the sorting device 200 can be facilitated, and the inspection and maintenance efficiency of the sorting device 200 can be improved.

[0065] In some embodiments, as Figure 4As shown, the sorting device 200 can further include a baffle 280 arranged below the sorting mechanism 230 for separating the sorted materials. The sorting mechanism 230 of the sorting device 200 can sort and separate the materials according to the identified material types. Since the sorting device 200 sorts the materials by changing the motion state of the materials by external force to change the motion trajectory of the sorting device 200, the materials can fall into the wrong discharge pipeline or be stuck between the first discharge pipeline 121 and the second discharge pipeline 122 due to external interference or sorting errors of the sorting device 200 during the falling process after the motion trajectory of the materials is changed. Therefore, the baffle 280 can be arranged below the sorting mechanism 230 of the sorting device 200 to separate the top ends of the first discharge pipeline 121 and the second discharge pipeline 122 by the baffle 280. In some embodiments, since the identification mechanism 220 can have a fan-shaped identification range, the end of the feeding conveying mechanism 210 can be arranged in an arc shape to facilitate the identification mechanism 220 to identify the materials falling from the end of the feeding conveying mechanism 210. Since the materials fall along the arc-shaped end, the sorting mechanism 230 can also be arranged in an arc shape to facilitate more accurate sorting of the materials. The first discharge pipeline 121 and the second discharge pipeline 122 also need to be adapted, such as Figure 6 As shown, the first discharge pipeline 121 and the second discharge pipeline 122 are arranged in an arc shape to receive the materials. Figure 6 As shown, the top section of the first discharge pipeline 121 can be arranged in a concave shape to adapt to the arc-shaped end structure of the feeding conveying mechanism 210, and the top section of the second discharge pipeline 122 can be arranged in a convex shape to adapt to the arc-shaped end structure of the feeding conveying mechanism 210. The baffle 280 between the first discharge pipeline 121 and the second discharge pipeline 122 can also be arranged in an arc shape. The first conveying device 140 and the second conveying device 150 can be arranged linearly along the extension direction of the scraper conveyor 130 according to the overall design of the auxiliary device, and therefore the bottom of the first discharge pipeline 121 and the second discharge pipeline 122 can be arranged in a rectangular shape to facilitate the transmission of the first target materials and the second target materials to the first conveying device 140 and the second conveying device 150. Through this embodiment, the first target materials and the second target materials can be separated by the baffle 280 to avoid mixing of the first target materials and the second target materials, and the accuracy of material sorting can be improved. The baffle 280 can prevent the materials from being stuck, effectively improving the stability and reliability of the material sorting device 200.

[0066] Based on the same inventive concept, the disclosure also provides a parallel sorting system, as shown in Figure 1 ,Figure 2 As shown, the auxiliary device can comprise: the auxiliary device of any one of the preceding embodiments; a plurality of sorting devices 200 of any one of the preceding embodiments, arranged side by side on the bottom support 120 along the extension direction of the auxiliary device, and arranged below the feeding ports one by one. The plurality of sorting devices 200 can be arranged side by side on the bottom support 120 along the extension direction of the auxiliary device, i.e. the extension direction of the scraper conveyor 130. Each sorting device 200 can be arranged corresponding to a feeding port, so that each sorting device 200 can receive the material fed by the corresponding feeding port and perform sorting respectively, and finally transport the sorted material to the subsequent processing or storage device through the first conveying device 140 and the second conveying device 150. For the parallel sorting system, the sorting devices 200 arranged on the bottom support 120 can be of the same type, so as to facilitate the sorting of the material. The sorting devices 200 arranged on the bottom support 120 can also be of different types, and a plurality of sorting devices 200 capable of sorting different particle sizes or different sizes of material can be arranged side by side, and according to the type and size of each sorting device 200, the size of the material leakage gap 1311 corresponding to each sorting device 200 can be changed, so that different sizes of material or different particle sizes of material can be sorted in the same parallel sorting system.

[0067] Specifically, at the beginning of the work of the parallel sorting system, the auxiliary device scraper conveyor 130 can be started first, and the material to be sorted can be transported to the sorting device 200 above the scraper conveyor 130. For multiple sorting devices 200 arranged in parallel and working simultaneously, the material to be sorted can be evenly distributed to each sorting device 200 through the scraper conveyor 130 to ensure the highest material sorting efficiency. Therefore, the driving device 134 of the scraper conveyor 130 can be used to drive each bottom plate 133 in the middle groove 131 to move and adjust the size of each material leakage gap 1311. Taking a parallel sorting system with three sorting devices 200 as an example, the first sorting device 200 arranged in the conveying direction of the scraper conveyor 130 can be provided with a smaller material leakage gap 1311, and the bottom plate 133 can be set as a small opening state bottom plate 133. A small part of the material being conveyed by the scraper conveyor 130 enters the first sorting device 200, and the remaining material continues to be conveyed by the scraper conveyor 130 to the subsequent sorting device 200. For the second sorting device 200, the size of the material leakage gap 1311 can be increased, and the corresponding bottom plate 133 above the sorting device 200 can be set as a large opening state bottom plate 133 by the driving device 134, so that part of the material enters the second sorting device 200. For the third sorting device 200, the size of the material leakage gap 1311 can be set to the maximum value, and the corresponding bottom plate 133 above the sorting device 200 can be set as a full opening state bottom plate 133 by the driving device 134, so that all the remaining material enters the third sorting device 200. For a parallel sorting system including multiple sorting devices 200, the material leakage gap 1311 can be gradually increased, and the material leakage gap 1311 at the tail of the scraper conveyor 130 can be set to the maximum value, so that all the remaining material can enter the last sorting device 200 corresponding thereto, and it can be ensured that each sorting device 200 corresponding to the material leakage gap 1311 can receive the same amount of material. To prevent material accumulation, a tail cleaning device can be provided at the material leakage gap 1311 corresponding to the last sorting device 200, and the cleaned material can also fall into the last sorting device 200. After the material falls into the sorting device 200, the material can be dispersed and smoothly conveyed by the feeding conveying mechanism 210. The material can fall from the end of the feeding mechanism, the type of the material can be determined by the identification mechanism 220, and the material can be sorted by the sorting mechanism 230 according to the identified result, so that the first target material enters the first material outlet pipe 121 corresponding thereto and is conveyed to the first conveying device 140 through the first material outlet pipe 121. The first conveying device 140 receives all the first target material falling from the sorting device 200 and conveys it to the subsequent processing equipment or collection equipment.The material is sorted by the sorting mechanism 230, so that the second target material enters the second discharge pipeline 122 corresponding to it, and is delivered to the second conveying device 150 through the second discharge pipeline 122. The second conveying device 150 receives all the second target material falling from the sorting equipment 200 and conveys it to the subsequent processing equipment or collection equipment, thereby completing the work of the parallel sorting system.

[0068] The parallel sorting system provided by the embodiment can realize parallel operation of multiple sorting equipment 200, effectively improve the sorting efficiency, and increase the sorting amount of the material. One scraper conveyor 130 installed on the top layer support 110 can uniformly supply material to multiple sorting equipment 200, and multiple sorting equipment 200 installed side by side on the bottom layer support 120 can sort the material respectively, so that the material can be sorted by multiple sorting equipment 200 in parallel, effectively improving the efficiency of material sorting and increasing the yield. The multiple sorting equipment 200 is installed on the auxiliary device, so that the scraper conveyor 130 and the sorting equipment 200 are arranged in the longitudinal direction and are located at different heights respectively, which can make the arrangement of the sorting equipment 200 more compact, effectively save space, and improve the space utilization.

[0069] In some embodiments, the parallel sorting system can include a connecting pressing plate assembly 300, which is arranged on the ground plates 290 of two adjacent sorting devices 200 and fixed to the bottom support 120, and used to fix the adjacent sorting devices 200. Since the sorting device 200 is provided with a feeding conveying mechanism 210, which can be a vibrating feeder. The vibration of the vibrating feeder can cause the vibration of the sorting device 200, which can cause the position deviation of the sorting device 200. Since the interval between the sorting devices 200 is small, the current sorting device 200 can collide with the adjacent sorting device 200. The connecting pressing plate assembly 300 can be arranged to fix the ground plates 290 of the adjacent sorting devices 200 to each other, so as to ensure the relative fixation of the adjacent sorting devices 200 and avoid the collision or interference between the sorting devices 200. The bottom of the ground plate 290 of the sorting device 200 can also be provided with an anti-skid device, so as to avoid the sliding of the sorting device 200 and at the same time play a certain damping effect. The connecting pressing plate assembly 300 can be arranged on the ground plates 290 of two adjacent sorting devices 200, and the connecting pressing plate assembly 300 can be fixed to the bottom support 120 by bolts, so that the ground plates 290 of two adjacent sorting devices 200 are fixed by the same connecting pressing plate assembly 300, so as to avoid the relative movement between the two adjacent sorting devices 200 and ensure the stability of the two adjacent sorting devices 200 during the working process. Through the embodiment, the two adjacent sorting devices 200 can be kept relatively static by the connecting pressing plate assembly 300, the installation stability of the sorting device 200 is improved, and in addition, the vibration of the sorting device 200 can be avoided, so as to avoid the position deviation of the sorting device 200 during the working process. Through the connecting pressing plate assembly 300, the collision and interference between the two adjacent sorting devices 200 due to the deviation can also be avoided, and the running stability and safety of the parallel sorting system are improved.

[0070] In some embodiments, as shown in Figure 7 , Figure 8 The connecting pressing plate assembly 300 can include an upper pressing plate 310 and a lower limiting plate 320.

[0071] The upper pressing plate 310 covers the ground plates 290 of the two adjacent sorting devices 200. The upper pressing plate 310 can be in the shape of a concave letter, covering the ground plates 290 of the two adjacent sorting devices 200 while avoiding the extended structure on the upper part of the ground plate 290 of the sorting device 200, so as to ensure the installation stability of the upper pressing plate 310 on the ground plates 290 of the two adjacent sorting devices 200. The ground plates 290 of the two adjacent sorting devices 200 are fixed and pressed by the upper pressing plate 310, so as to ensure the stability of the two adjacent sorting devices 200 in the height direction. The upper pressing plate 310 can be provided with a strip-shaped adjusting long hole, and a bolt can pass through the adjusting long hole to fix the upper pressing plate 310 on the bottom support. According to the position of the ground plate 290 of the sorting device 200, the bolt can move in the adjusting long hole along the extension direction of the adjusting long hole, so as to adjust the position of the upper pressing plate 310, so that the upper pressing plate 310 can cover the ground plates 290 of the two adjacent sorting devices 200, and the installation stability is ensured.

[0072] The lower limiting plate 320 is arranged below the upper pressing plate 310 and is arranged beside the ground plate 290 in the shape of a v-shaped plate, which is used to clamp the ground plates 290 of the two adjacent sorting devices 200. The lower limiting plate 320 can be arranged below the upper pressing plate 310 and has the same thickness as the ground plate 290, so that the lower limiting plate 320 and the ground plate 290 are pressed by the upper pressing plate 310 and the bottom support. The lower limiting plate 320 can include two strip-shaped plates arranged beside the ground plates 290 of the two adjacent sorting devices 200, so that the two strip-shaped lower limiting plates 320 are arranged in the shape of a v-shaped plate, thereby clamping the ground plates 290 of the two adjacent sorting devices 200, and the two adjacent sorting devices 200 are limited by the lower limiting plate 320 in the horizontal direction and cannot move, thereby effectively providing the installation stability of the sorting device 200.

[0073] According to the embodiment, the lower limiting plate 320 and the ground plates 290 of the two adjacent sorting devices 200 are pressed by the upper pressing plate 310, so as to effectively limit the movement of the sorting device 200 in the vertical direction, avoid the offset caused by the vibration of the sorting device 200 in the vertical direction, and ensure the stability of the sorting device 200 during operation. The movement of the sorting device 200 in the horizontal direction is effectively limited by the lower limiting plate 320, so as to avoid the offset caused by the vibration of the sorting device 200 in the horizontal direction, thereby enabling the sorting device 200 to be stable and firm, and the installation of the sorting device 200 has better stability and safety.
