[0020] It is worth noting that pulley 404 and cam 405 are in sliding contact with the outer periphery, in operation, motor 408 is started, the output end of motor 408 drives main shaft 401 and cam 405 to rotate, under the action of the sliding contact of pulley 404 and the outer periphery of cam 405, scraper 403 is driven to reciprocate left and right, since torsion spring 407 is arranged around the both ends of support shaft 402, one end of torsion spring 407 is fixedly connected with the outer side wall of scraper 403, the other end is connected with the outer side wall of support shaft 402, therefore, in the process of reciprocating forward and backward of scraper 403, torsion spring 407 can play the role of buffering reset, improve the service life of scraper 403, the rotation of main shaft 401 and cam 405 driven by motor 408 makes scraper 403 can produce periodic up-down motion, further enhances the scraping effect, improves the cleaning efficiency.

[0021] Please refer to Figure 2 , the top of trapezoidal box 1 at low position is provided with first open mouth 101, trapezoidal box 1 is provided with second open mouth 102 on one side at high position, first open mouth 101 is used for feeding, second open mouth 102 is used for discharging to the material receiving equipment.

[0022] Please refer to Figure 2 andFigure 3 The sweeping structure 2 includes a sweeping plate 203 and a rotating shaft 204. A plurality of rotating shafts 204 are uniformly arranged above the conveying belt 3 inside the trapezoidal box 1. The two ends of the rotating shaft 204 are rotatably connected to the adjacent side of the trapezoidal box 1. The outer side wall of the rotating shaft 204 is fixedly connected to a plurality of groups of sweeping plates 203. Each group of sweeping plates 203 has three sweeping plates 203 arranged in a ring shape. One end of the rotating shaft 204 rotatably penetrates the front end face of the trapezoidal box 1. The penetrating end is connected to a belt pulley 205. One end of the main shaft 401 rotatably penetrates the front end face of the trapezoidal box 1. The penetrating end is also connected to a belt pulley 205. The belt pulleys 205 are drivingly connected by a belt 206.

[0023] When the main shaft 401 rotates, the rotating shaft 204 can be driven to rotate synchronously through the transmission action of the belt 206 and the belt pulley 205. Since the outer side wall of the rotating shaft 204 is fixedly connected to a plurality of groups of sweeping plates 203, each group of sweeping plates 203 has three sweeping plates 203 arranged in a ring shape. Therefore, when the rotating shaft 204 rotates, the sweeping plates 203 will rotate with it to sweep the material on the conveying belt 3. This design can ensure that the material remains flat during conveying, avoiding material accumulation or scattering, thereby improving the efficiency and stability of material conveying. At the same time, since the sweeping plates 203 are uniformly arranged, the material on the conveying belt 3 can be swept evenly and efficiently.

[0024] Referring to Figure 3 The sweeping plates 203 on the rotating shaft 204 are distributed in a staggered manner with the sweeping plates 203 on the adjacent rotating shaft 204. This staggered distribution design can further optimize the sweeping effect. When the sweeping plates 203 on the adjacent rotating shaft 204 are distributed in a staggered manner, each sweeping plate 203 can more effectively cover the material on the conveying belt 3 during rotation, reducing the sweeping blind area. At the same time, the staggered distribution of the sweeping plates 203 can interleave with each other during rotation, forming a more dense sweeping network, thereby improving the uniformity and efficiency of sweeping.

[0025] Referring to Figure 1 The trapezoidal box 1 is connected to a long box 201 at the position of the belt pulley 205. The penetrating ends of the rotating shaft 204 and the main shaft 401 are arranged inside the long box 201. The belt pulley 205 is arranged inside the long box 201. The long box 201 is provided with a cover plate 202 installed at the front end. The design of the long box 201 provides stable support and protection for the rotating shaft 204 and the main shaft 401. It also provides a closed environment for the transmission of the belt 206 and the belt pulley 205, reducing dust and impurity interference and improving the stability and durability of the transmission. The arrangement of the cover plate 202 facilitates maintenance and repair of the inside of the long box 201.

[0026] Referring to Figure 3, the bottom side wall of the scraper 403 is in contact with the outer side of the conveying belt 3, the outer side wall of the cam 405 is in intermittent contact with the outer side wall of the pulley 404, when the cam 405 rotates, the outer side wall of the cam 405 is in periodic contact with the outer side wall of the pulley 404, the pulley 404 and the scraper 403 connected therewith are pushed to move along the width direction of the conveying belt 3, the intermittent contact and movement enable the scraper 403 to periodically sweep the outer side of the conveying belt 3, effectively removing the residual material and impurities attached to the conveying belt 3, and keeping the conveying belt 3 clean, and the close contact between the bottom side wall of the scraper 403 and the outer side of the conveying belt 3 ensures the thoroughness and effectiveness of the sweeping.

[0027] Working principle: after the device is started, the motor 408 starts to work, the output end of the motor 408 drives the main shaft 401 to rotate, the rotation of the main shaft 401 in turn drives the cam 405 to rotate, since the outer periphery of the cam 405 is in sliding contact with the pulley 404 at the center of the side of the scraper 403, with the rotation of the cam 405, the pulley 404 and the scraper 403 connected therewith are pushed to reciprocate left and right in the width direction of the conveying belt 3, the reciprocation of the scraper 403 is buffered and reset by the torsion spring 407 on the support shaft 402, which not only enhances the scraping effect, but also prolongs the service life of the scraper 403,

[0028] Meanwhile, the rotation of the main shaft 401 also drives the multiple rotating shafts 204 arranged uniformly inside the trapezoidal box 1 to rotate synchronously through the transmission action of the belt 206 and the belt pulley 205, the sweeping plates 203 fixedly connected to the outer side wall of each rotating shaft 204 rotate in turn, and the material on the conveying belt 3 is swept flat, the annular arrangement and staggered distribution design of the sweeping plates 203 ensure that the material remains flat during the conveying process, avoid the accumulation or scattering of the material, and improve the efficiency and stability of the material conveying,

[0029] In addition, the close contact between the bottom side wall of the scraper 403 and the outer side of the conveying belt 3 enables the scraper 403 to periodically sweep the outer side of the conveying belt 3 under the pushing of the cam 405, effectively removes the residual material and impurities attached to the conveying belt 3, and keeps the conveying belt 3 clean,

[0030] The entire device realizes the reciprocating swing of the scraper 403 and the rotating sweeping operation of the sweeping plate 203 through the driving of the motor 408, thereby ensuring the flatness and cleanliness of the material during the conveying process, and improving the efficiency and stability of the material conveying.
