[0024] Reference Figure 1-3Four mutually parallel support columns 11 are fixedly arranged on the support base plate 1, and the four support columns 11 are evenly distributed at the corners of the support base plate 1, and an anti-skid plate 12 is fixedly arranged on the bottom end of each support column 11. By arranging four support columns 11 on the support base plate 1, the support function of the device body is realized, and by arranging each support column 11 at each corner of the support base plate 1, it is ensured that each support column 11 can be subjected to uniform force, and the damage of each support column 11 due to uneven force is avoided. The anti-skid plate 12 arranged on the bottom end of the support column 11 can increase the friction between the support column 11 and the ground, and avoid the slipping and deviation of the device during use.

[0025] Reference Figure 2-4 A feed hopper 221 is fixedly provided on the upper end of the storage box 22, and the feed hopper 221 is funnel-shaped with a large top and a small bottom. By setting the feed hopper 221 on the storage box 22, the wide-mouthed feed hopper 221 can facilitate the staff to add materials when adding materials, which is simple and convenient.

[0026] Reference Figure 2 , 3 The transmission mechanism 5 includes two gears 51 fixedly arranged on the roller shafts of the two crushing rollers 23, and the two gears 51 are meshed with each other. The crushing rollers 23 and the outer circumferential surfaces of the rotating shaft 34 are fixedly provided with pulleys 52, and the two pulleys 52 are connected by belt transmission. When the staff starts the servo motor 24 to drive the crushing roller 23 to rotate, the pulley 52 fixedly arranged on the crushing roller 23 is driven to rotate, and then the rotating shaft 34 is driven to rotate by the belt.

[0028] Reference Figure 3-5A screening chamber 6 for processing materials is formed between the inner shell 33 and the outer shell 32. A scraper 61 is rotatably arranged in the screening chamber 6. By setting the screening chamber 6 between the inner shell 33 and the outer shell 32, the screened materials can be pushed by the scraper 61 and finally discharged and collected during the use of the device.

[0029] Reference Figure 3-5 A connecting plate 62 is fixedly provided on the end of the rotating shaft 34 away from the crushing device 2, and a shaft body 63 is rotatably provided at the end of the connecting plate 62. The shaft body 63 is rotatably connected to the scraper 61. The connecting plate 62 provided on the rotating shaft 34 enables the shaft body 63 connected by the connecting plate 62 to rotate around the rotating shaft 34 during the rotation of the rotating shaft 34, thereby controlling the scraper 61 to rotate and transport materials.

[0030] Reference Figure 5-7 A long plate 7 is fixedly arranged on the outer circumference of the shaft body 63, and the multiple long plates 7 are evenly arranged. The long plates 7 arranged on the outer circumference of the shaft body 63 can realize secondary stirring of the material in the screening chamber 6 to ensure that the material inside is mixed, which is convenient for the device to discharge the material.

[0031] Reference Figure 4-6 The inner wall of the outer shell 32 is fixedly provided with teeth, and the shaft body 63 is fixedly provided with a gear 2 64 meshing with the teeth. The teeth arranged on the outer shell 32 enable the shaft body 63 arranged on the gear 2 64 to realize its own rotation during the rotation of the shaft 34, thereby ensuring that the material in the screening chamber 6 is stirred and discharged conveniently.

[0032] Reference Figure 5-7 The width of the scraper 61 is equal to the width of the screening chamber 6. By setting the width relationship between the scraper 61 and the screening chamber 6, the material in the screening chamber 6 can be fully pushed during the rotation of the scraper 61, thereby avoiding the accumulation of materials in the shell 32.

[0033] The specific scheme is as follows: when using the device, the staff first moves the device to a suitable position, and then places the material to be processed in the feed hopper 221 on the device. By setting four support columns 11 on the support base plate 1, the support function of the device body is realized, and by setting each support column 11 at each corner of the support base plate 1, it is ensured that each support column 11 can be evenly stressed, avoiding the situation that each support column 11 is damaged due to uneven stress. The anti-skid plate 12 set on the bottom end of the support column 11 can increase the friction between the support column 11 and the ground, avoiding the situation that the device slips and deviates during use. The guide plate 41 set in the storage box 22 is realized. When the staff puts the material into the storage box 22, the material enters the material transport trough 42 in the device through the guide plate 41, and then starts the servo motor 24. The rotating servo motor 24 controls the crushing roller 23 to rotate and crush the material. The crushed material is transported to the next place of the device through the auger 43. When the staff starts the servo motor 24 to drive the crushing roller 23 to rotate, it drives the pulley 52 fixed on the crushing roller 23 to rotate, and then drives the rotating shaft 34 to rotate through the belt. The connecting plate 62 arranged on the rotating shaft 34 realizes that during the rotation of the rotating shaft 34, the shaft body 63 connected by the connecting plate 62 can rotate around the rotating shaft 34, thereby controlling the scraper 61 to rotate and transport materials.
