Through this arrangement, the conveyor belt 503 can be driven by the electric roller 502 to move, and the material can be shielded by the connecting strip 504 and the card shell 506, so that the material can be stably transmitted. When the belt piece 503 is damaged, the card strip 509 can be directly taken out, and then the bolt 507 can be taken out. At this time, the card shell 506 can be removed from the connecting strip 504. After the card shells 506 at both ends of the conveyor belt piece 503 are removed, the conveyor belt piece 503 can be replaced. After replacement, the two connecting strips 504 are installed by bolts 507 and nuts 508, and then the card strip 509 is installed in the installation groove 513 opened by the card shell 506. When the conveyor belt piece 503 is in use, the conveyor belt piece 503 and the connecting strip 504 are reinforced by the L-shaped plate 505. At the same time, the bolt 507 passes through the L-shaped plate 505 to make the installation between the conveyor belt pieces 503 more stable.

[0017] like Figure 10-14As shown, the cleaning body 6 includes a storage shell 601, a servo motor 602, a rotating shaft 604 and bristles 605. The storage shell 601 is fixedly connected to the fixed plate 501. Two connecting plates 603 are fixedly connected to the right side of the storage shell 601. The connecting plate 603 is fixedly connected to the servo motor 602 on the side away from the storage shell 601. The output shaft of the servo motor 602 passes through the connecting plate 603 and is rotatably connected to the rotating shaft 604. The end of the rotating shaft 604 away from the servo motor 602 is rotatably connected to the storage shell 601. Bristles 605 are installed on the outside of the rotating shaft 604. A storage box 7 is provided under the storage shell 601. A top plate 9 is provided on the top of the storage shell 601. The top plate 9 is provided with a material discharge trough. The top of the storage box 7 is fixedly connected with a blanking shell 10, and a bevel is provided on one side of the blanking shell 10. A rubber pad 11 is fixedly connected to the bevel position of the blanking shell 10. The side of the rubber pad 11 away from the blanking shell 10 is tightly fitted with the storage shell 601. Second support rods 3 are provided on the left and right sides of the storage box 7. The connecting body 8 is provided on the outside of the two second support rods 3. The bottom of the top plate 9 is fixedly connected with a rubber frame 12. The outside of the rubber frame 12 is tightly fitted with the storage shell 601. The connecting body 8 includes a mounting plate 801 and a card block 806. The rear side of the mounting plate 801 is fixedly connected to the storage box 7. The left and right ends of the rear side of the mounting plate 801 are fixedly connected to a fixed shell 802. A slide plate 803 is provided in the fixed shell 802. The slide plate 80 3 is fixedly connected to the right side of the connecting rod 804, and a clamping spring 805 is set on the outside of the connecting rod 804. The outside of the end of the connecting rod 804 away from the slide 803 is rotatably connected to the block 806. The front side of the block 806 is tightly fitted with the second support rod 3. Through this arrangement, the servo motor 602 can drive the rotating shaft 604 and the brush 605 to rotate, and the brush 605 cleans the surface of the conveyor belt 503. The cleaned residue falls into the storage shell 601, and then enters the storage box 7 through the discharge shell 10 under the action of gravity for collection. When there is too much residue in the storage box 7, the block 806 is directly rotated, and then the storage box 7 is driven to move through the fixed shell 802 and the mounting plate 801 to store the storage box 7. After that, the top plate 9 is taken out from the storage box 7 by the blanking shell 10, and the residue in the storage box 7 is taken out and cleaned. After cleaning, the top plate 9 is installed back on the top of the storage box 7. At this time, the outer side of the rubber frame 12 is tightly fitted with the storage box 7, so as to position the top plate 9, and then the storage box 7 is installed back between the second support rods 3, and the block 806 is moved to the back side of the second support rod 3. At this time, the clamping spring 805 drives the connecting rod 804 and the block 806 to move through the slide plate 803, so that the connecting plate 603 and the block 806 are clamped on the outside of the second support rod 3, so as to install the storage box 7. At the same time, the rubber pad 11 is tightly fitted with the storage shell 601, so that the residue can fall accurately into the blanking shell 10.

[0018] Working process: When using this crushing and reducing machine feeding device, first turn on the power supply, then place the material to be crushed on the conveyor belt 503, and start the electric roller 502 through the control body 4. The electric roller 502 drives the conveyor belt 503 to move. At this time, the conveyor belt 503 drives the material to be transported obliquely upward through the connecting strip 504 and the card shell 506 until the material falls into the crushing and reducing machine, and is crushed and reduced by the crushing and reducing machine. The rotation speed of the electric roller 502 is controlled by the control body 4, thereby automatically adjusting the feeding speed. After the material leaves the conveyor belt 503, the conveyor belt 503 moves into the storage shell 601. At this time, the servo motor 602 is started through the control body 4, and the servo motor 602 drives the rotating shaft through the output shaft 604 rotates, and the rotating shaft 604 drives the bristles 605 to sweep across the surface of the conveyor belt piece 503, sweeping off the residue on the surface of the conveyor belt piece 503, and then the residue falls into the storage shell 601. Under the action of gravity, the residue enters the storage box 7 through the discharge shell 10 and is stored in the storage box 7. When there is too much residue in the storage box 7, the block 806 is directly rotated to make the block 806 leave the rear side of the second support rod 3, and then the storage box 7 is driven to move by the fixed shell 802 and the mounting plate 801, and the storage box 7 is removed from the bottom plate 1, and then the discharge shell 10 is moved upward, and the discharge shell 10 drives the top plate 9 and the rubber frame 12 to move upward, and then the residue in the storage box 7 can be poured out and collected, and the storage box 7 is cleaned. After cleaning, the top plate 9 is mounted on When the clamping block 806 is in the upright position, the clamping block 806 is rotated to move the end of the clamping block 806 away from the connecting rod 804 and is arranged on the rear side of the second supporting rod 3. Then the clamping block 806 is released, and the clamping spring 805 pushes the connecting rod 804 and the clamping block 806 to move, so that the clamping block 806 is in close contact with the second supporting rod 3. The receiving shell 601 fits tightly, so that the residue can accurately pass through the blanking shell 10 and fall into the storage box 7. When part of the conveyor belt 503 is severely worn, first remove the card strip 509 from the installation groove 513 opened in the fixed plate 501, and then use a tool to rotate the bolt 507 and the nut 508 to remove the nut 508 from one end of the bolt 507. At this time, the bolt 507 can be removed from the card shell 506, and then the card shell 506 is removed from the outside of the connecting strip 504. Then, the card shell 506 set at the other end of the conveyor belt piece 503 is removed in the same way as above. At this time, one conveyor belt piece 503 can be removed, and the connecting strip 504 set on one side of the new conveyor belt piece 503 is brought into contact with the connecting strip 504 set on the undisassembled conveyor belt piece 503.Then, clamp the housing 506 on the outside of the two connecting strips 504, insert the bolt 507 through the housing 506 and the connecting strip 504, and thread the nut 508 onto one end of the bolt 507. After the bolt 507 and the nut 508 are installed, install the clamping strip 509 into the installation groove 513 provided in the housing 506. At this time, one end of the bolt 507 and the nut 508 are respectively placed in the placement groove 511 provided in two different clamping strips 509. At the same time, the outer side of the rubber sleeve 510 is tightly fitted with the inner wall of the installation groove 513 provided in the housing 506, thereby positioning the clamping strip 509. Then, install the other end of the conveyor belt 503, thereby completing the replacement of the conveyor belt 503.
