[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] like Figures 1 to 3 As shown, the embodiment of the utility model provides a sorting device, which includes a bracket 100, a buffer plate 200, a dial plate 300, a driving member 400 and a second buffer structure. The buffer plate 200 is arranged on the bracket 100, and there is an angle between the buffer plate 200 and the vertical direction. The buffer plate 200 has a first buffer structure, the dial plate 300 is arranged on the bracket 100 and is located below the buffer plate 200, the dial plate 300 has a connecting end and a free end that are relatively arranged, the connecting end is located above the free end and is hinged to the bracket 100, and the material passing through the first buffer structure can fall to the dial plate 300, and the driving member 400 is connected to the dial plate 300 to adjust the angle of the dial plate 300 in the horizontal direction, thereby changing the falling position of the material. The second buffer structure is arranged between the driving member 400 and the dial plate 300 to buffer the impact of the dial plate 300 on the driving member 400.

[0032] By applying the technical solution of the present utility model, the material falling from the end of the conveyor belt will first fall to the buffer plate 200, and then fall to the paddle plate 300. During this process, the first buffer structure on the buffer plate 200 will initially buffer the material to reduce the kinetic energy of the material. When the driving member 400 drives the paddle plate 300 to rotate relative to the bracket 100, the paddle plate 300 will hit the material that has been initially buffered. The impact of the material on the driving member 400 through the paddle plate 300 will be buffered again by the second buffer mechanism to reduce the impact on the driving member 400. By providing the first buffer structure and the second buffer structure, the present application can buffer the material multiple times, reduce the impact on the driving member 400, and further increase the service life of the driving member 400, reduce the risk of damage to the driving member 400 due to impact, and ensure the normal operation of the sorting system.

[0033] Specifically, in the present application, the second buffer structure includes a connecting rod assembly 310, which is disposed between the driving member 400 and the dial plate 300. The driving member 400 has a telescopic end, one end of the driving member 400 is hinged to the bracket 100, and the telescopic end is drivingly connected to the connecting rod assembly 310, so as to drive the dial plate 300 to rotate through the connecting rod assembly 310. Through the above arrangement, the connecting rod assembly 310 can play the role of connection and transmission, and when the impact on the dial plate 300 is transmitted to the driving member 400, the connecting rod assembly 310 will disperse and absorb part of the kinetic energy, thereby increasing the service life of the driving member 400.

[0034] Specifically in the present application, the connecting rod assembly 310 can be configured as a pneumatic cylinder.

[0035] In a specific embodiment of the present application, the connecting rod assembly 310 includes a first connecting rod 311 and a second connecting rod 312 that are hinged to each other, one end of the first connecting rod 311 away from the second connecting rod 312 is hinged to the dial plate 300, one end of the second connecting rod 312 away from the first connecting rod 311 is hinged to the bracket 100, and the driving member 400 is hinged to the second connecting rod 312 to drive the second connecting rod 312 to rotate relative to the bracket 100. Through the above arrangement, the first connecting rod 311 and the second connecting rod 312 can cooperate with each other to realize the transmission effect, and when the dial plate 300 is impacted, the first connecting rod 311 will transmit the impact force to the second connecting rod 312, and the second connecting rod 312 is connected to the driving member 400 and the bracket 100 respectively, so that the force received by the driving member 400 can be dispersed, so as to play a buffering role for the driving member 400 and reduce the impact force received by the driving member 400.

[0036] Specifically, refer to Figure 1 and Figure 2 As shown, in the process of the driving member 400 driving the paddle 300 to rotate around the connection between the bracket 100 and the paddle 300 in the present application, the sorting device has a first extreme position and a second extreme position which are relatively set. When the sorting device is in the first extreme position, the paddle 300 is completely located below the buffer plate 200, and the material will only pass through the buffer plate 200 once. The paddle 300 will not change the falling trajectory of the material. There is an angle between the first connecting rod 311 and the second connecting rod 312. When the sorting device is in the second extreme position, the driving member 400 can drive the second connecting rod 312 and push the first connecting rod 311, thereby causing the paddle 300 to rotate in a direction away from the driving member 400. The paddle 300 hits the material in the process of the sorting device switching from the first extreme position to the second extreme position to change the falling trajectory of the material.

[0037] Specifically in the present application, a limiting structure is provided between the first connecting rod 311 and the second connecting rod 312 to limit the relative rotation range between the first connecting rod 311 and the second connecting rod 312. Figure 1 and Figure 2As shown, when the sorting device is in the first extreme position, if the first connecting rod 311 needs to push the second connecting rod 312 to rotate, a certain angle must exist between the first connecting rod 311 and the second connecting rod 312, otherwise the second connecting rod 312 may rotate clockwise around the hinge with the bracket 100, and the first connecting rod 311 may also rotate clockwise around the hinge with the second connecting rod 312; when the sorting device is in the second extreme position, if the dial plate 300 continues to rotate, it may interfere with the buffer plate 200. In the present application, a limiting structure is provided to limit the range of relative rotation between the first connecting rod 311 and the second connecting rod 312 to ensure the working effect of the connecting rod assembly 310.

[0038] Specifically, the limiting structure may be in the form of a limiting block or a limiting rod, etc. The limiting block or the limiting rod is arranged on the first connecting rod 311 or the second connecting rod 312 to limit the relative rotation angle between the first connecting rod 311 and the second connecting rod 312 .

[0039] Furthermore, the rotation range of the first connecting rod 311 and the second connecting rod 312 can be further limited by adjusting the stroke of the driving member 400 to control the rotation range of the paddle 300, accurately control the falling trajectory of the material, and ensure the sorting effect of the sorting device.

[0040] Specifically in the present application, the upper surface of the buffer plate 200 has a recessed portion 201, and the recessed portion 201 forms a first buffer structure. Through the above arrangement, when the material first contacts the buffer plate 200, the buffer plate 200 can first absorb part of the kinetic energy of the material and buffer the material once. When the material moves along the extension direction of the buffer plate 200 in the height direction, because the upper surface of the buffer plate 200 has a recessed portion 201, the buffer plate 200 forms a recessed structure, which can stop the movement of the material or change the movement trajectory of the material to reduce the kinetic energy of the material movement. The recessed portion 201 and the buffer plate 200 body stop the material to form a primary buffer to reduce the kinetic energy of the material when it falls to the paddle plate 300, thereby reducing the impact on the driving member 400.

[0041] Specific as Figure 1 and Figure 2 As shown, in the first embodiment of the present application, the buffer plate 200 includes a first section 210 and a second section 220 connected in sequence, the first section 210 is arranged above the second section 220, and an angle is formed between the extension direction of the second section 220 and the extension direction of the first section 210. With such an arrangement, after falling to the first section 210, the material will fall to the second section 220 again, stopping the falling of the material and reducing the kinetic energy of the material.

[0042] like Figure 3As shown, in the second embodiment of the present application, unlike the first embodiment, the buffer plate 200 is an integrated structure, and the upper surface of the buffer plate 200 is formed by a smooth transition. The buffer plate 200 guides the movement trajectory of the material, guides the movement trajectory of the material, reduces the angle between the movement trajectory of the material and the paddle plate 300 when the material contacts the paddle plate 300, and further reduces the force of the paddle plate 300 on the connecting rod assembly 310, thereby achieving a buffering effect on the material.

[0043] Specifically in the present application, the angle between the buffer plate 200 and the height direction can be adjusted according to the diameters of the materials to be sorted, so that the materials can contact the buffer plate 200 before the prying plate 300 .

[0044] According to an embodiment of the present application, a sorting system is also provided, such as Figure 4 As shown, the sorting system includes a conveyor belt 01, a sorting chute 02, a sorting device and a control mechanism. Among them, the sorting chute 02 is arranged below one end of the conveyor belt 01, and the sorting chute 02 has a plurality of channels 021, and the plurality of channels 021 are arranged at intervals along the transport direction of the conveyor belt 01. The sorting device is the above-mentioned sorting device, and the sorting device is located between the conveyor belt 01 and the sorting chute 02 in the height direction; the control mechanism includes an identification unit and a control unit, and the identification unit is arranged corresponding to the conveyor belt 01, and the control unit is electrically connected to the identification unit and the driving member 400 of the sorting device respectively, and the identification unit can identify the material on the conveyor belt 01, and control the driving member 400 to drive the angle of the paddle 300 of the sorting device in the horizontal direction through the control unit, thereby changing the falling position of the material.

[0045] By applying the sorting device provided in the embodiment of the present application, when the material falls from the conveyor belt 01 to the sorting chute 02, the sorting device can hit the material to make the material fall to different channels 021, thereby completing the sorting of the material. The material is buffered multiple times during the sorting process, which can ensure the stable operation of the sorting device, reduce the risk of damage to the sorting device, and improve the working stability of the overall sorting system.

[0046] Specifically in the present application, a plurality of sorting devices are provided, and the plurality of sorting devices are arranged at intervals along the width direction of the conveyor belt 01, so that the plurality of sorting devices can work simultaneously to improve the sorting efficiency of the sorting devices.

[0047] In some feasible implementations of the present application, the recognition unit may be an AI camera system to accurately determine the composition of the material.

[0048] In some other embodiments of the present application, the identification unit includes an X-ray transmitter and an X-ray receiver. The X-ray transmitter is arranged above the upper crawler of the conveyor belt 01, and the X-ray receiver is arranged below the upper crawler of the conveyor belt 01. The X-ray receiver is used to collect X-rays that penetrate the material to be sorted, and the control unit can control the driving member 400 according to the identification result of the X-ray receiver. X-rays can penetrate the mixed material and be received by the X-ray receiver. Take the separation of gangue from raw coal in coal mine production as an example: when coal and gangue pass through the identification unit, the X-rays will produce different energy attenuation according to the different density of the material after penetrating the material, and the attenuated energy is collected by the X-ray receiver. For materials with high density, the penetration of X-rays is weak, and the attenuated energy will be more. For materials with low density, the penetration of X-rays is strong, and the attenuated energy is less. Since coal and gangue contain different elements, the density of coal is smaller than that of gangue, and the two absorb different amounts of radiation attenuation energy, with gangue having a strong absorption capacity and coal having a weak absorption capacity. The control unit establishes an analysis model adapted to different coal quality characteristics according to the different strengths of the received rays, obtains the size of the coal or gangue, and the width range of the conveyor belt 01, calculates the distance between the gangue or coal and the edge of the conveyor belt 01, and obtains the relative position of the gangue or coal on the conveyor belt 01. Multiple sorting devices are arranged in sequence along the width direction of the conveyor belt 01, and the paddles 300 of each sorting device are also arranged in sequence along the width direction of the conveyor belt 01. The control unit pre-stores the position of the paddles 300 corresponding to each driving member 400 on the conveyor belt 01. Relative position and width, the control unit can determine which one or which paddles 300 need to be controlled to move according to the size of the material and the relative position on the conveyor belt 01, and calculate the migration time required for the material to move to the discharge end of the conveyor belt 01 according to the result of the X-ray transmission ratio analysis that the material is gangue or coal, and combined with the running speed of the conveyor belt 01, output a control signal to the control end of the driving member 400 corresponding to the position of the gangue or coal, and control the paddle 300 to rotate to a specific angle within the set time before the migration time is reached, so as to guide the gangue or coal transmitted by the conveyor belt 01 to fall along different specific trajectories through the paddle 300, so that the material enters different channels 021, thereby separating the gangue and coal and realizing sorting.

[0049] Further in the present application, the sorting system also includes a magnetic separation device, which can remove magnetic materials from the materials to be sorted, and the magnetic separation device is arranged upstream of the control mechanism. Through the above arrangement, the magnetic separation device can remove impurities before the material is sorted, improve the sorting rate, and reduce the influence of materials such as iron on X-rays, thereby ensuring the accuracy of the recognition unit.
