[0030] When the conveyor mesh belt 4 is conveying, the U-shaped rod 11 will be driven to rotate synchronously through the pulley, and the rotating U-shaped rod 11 will drive the slide plate 7 to reciprocate up and down in the vertical direction. At this time, the outer peripheral wall of the U-shaped rod 11 slides back and forth in the slide groove 10 to correct the positional relationship between the U-shaped rod 11 and the slide plate 7. When the slide plate 7 drives the slapping mesh plate 8 to move upward, the slapping mesh plate 8 will squeeze the plurality of springs 9 in the direction of the fixed plate 6, so that the plurality of springs 9 are in a stressed state. When the flapping mesh plate 8 is driven to move downward, the stress state of the plurality of springs 9 is released, and the flapping mesh plate 8 is pressed downward, so that the flapping mesh plate 8 hits the top of the conveying mesh plate 1. When the flapping mesh plate 8 flaps the waste scraps on the conveying mesh plate 1, the dust attached to the surface of the waste scraps falls off, and the dust flapped from the waste scraps is restricted in the inner cavity of the dust cover 2 by the dust cover 2 and the dust tassel 5, and then the dust is sucked out of the dust cover 2 by starting the vacuum cleaner 12;

[0031] See also Figure 1-2 and Figure 4 As shown, two crushing rollers 13 rotating in opposite directions are rotatably installed in the processing box 3, and a driving motor for driving the crushing rollers 13 to rotate is provided on the processing box 3.

[0032] After the waste scraps are transported to the dust cover 2 through the conveyor mesh belt 14, the waste scraps are crushed by the two crushing rollers 13 rotating in opposite directions in the dust cover 2 in cooperation with the plurality of saw teeth 14, and the crushed waste scraps will fall to the top of the conveyor mesh belt 2 15 at the bottom of the dust cover 2. At the same time, the slide plate 21 that reciprocates up and down will drive the connecting plate 20 to push and pull the plurality of piston rods 19 in the direction of the piston cylinder 18 through the push-pull plate 1 23. When the plurality of piston rods 19 are pulled outward from the plurality of piston cylinders 18, the plurality of piston cylinders 18 will suck the liquid in the water storage tank 17 into the drain pipe. When the plurality of piston rods 19 are pushed into the plurality of piston cylinders 18, the liquid in the drain pipe will be squeezed onto the crushing roller 13 through the plurality of nozzles, so as to clean the waste scraps being crushed by the crushing roller 13.

[0033] The transmission mechanism 22 includes a connecting plate 221 fixedly installed at the bottom of the two slide plates 21, and a pair of rotating plates 222 are rotatably installed on both sides of the mounting frame 1.

The ends of the two push-pull plates 3 27 away from the connecting plate 1 20 are respectively rotatably connected to the tops of the two push plates 25. When the connecting plate 221 moves upward, the two symmetrical push-pull plates 3 27 will drive the two push plates 25 to approach each other, otherwise they will move away from each other.

[0036] See also Figure 1-2As shown, a squeezing roller 28 is rotatably installed on the mounting frame 1 near the rear side of the two push plates 25, and the bottom of the outer peripheral wall of the squeezing roller 28 is in contact with the top of the conveyor mesh belt 15. A heating plate 29 is fixedly installed on the mounting frame 1 near the rear side of the squeezing roller 28, and a heater for heating the heating plate 29 is installed on the mounting frame 1. The squeezing roller 28 is used to squeeze the waste scraps transported to the bottom of the waste scraps by the conveyor mesh belt 15 to squeeze out the moisture in the waste scraps, and then the waste scraps are transported to the bottom of the heating plate 29 by the conveyor mesh belt 15 to dry the waste scraps.

[0037] When the present invention is in use, the waste scraps to be processed are first placed in the front conveying area of ​​the conveyor mesh belt 4, and then the conveyor mesh belt 4 conveys the waste scraps to the processing box 3. During this process, the beating mesh plate 8 will beat the waste scraps conveyed to the dust cover 2 to separate the dust inside, and the dust will be sucked out of the dust cover 2 through the dust collector 12. When the beaten waste scraps are conveyed to the processing box 3, the two crushing rollers 13 moving in opposite directions cooperate with the several saw teeth 14 on the inner wall of the processing box 3 to crush them. During this process, the drainage ring pipe 16 will continuously spray clean water to the waste scraps being crushed to clean the waste scraps. The remaining dust in the material is cleaned, and the cleaned and crushed waste scraps fall to the front conveying area of ​​the conveyor mesh belt 215. At this time, the two pushing plates 25 moving in opposite directions drive the brushes 26 at the bottom to flatten the crushed waste scraps accumulated here on the top of the conveyor mesh belt 215, and then the flattened waste scraps are transported to the back side of the box through the conveyor mesh belt 215. When the waste scraps pass through the squeezing roller 28, they are squeezed by the squeezing roller 28 to squeeze out the moisture inside them, and then they are dried by the heating plate 29 to complete the processing of the waste scraps, and finally the processed waste scraps are sent to the designated position through the conveyor mesh belt 215.
