[0035] A plurality of feed rollers 2 are arranged in the box body 1, and the feed rollers 2 are rotatably arranged on the inner wall of the box body 1 through a rotating shaft, one end of the rotating shaft extends out of the box body 1, and a transmission belt 3 is connected between adjacent rotating shafts at the extended end, and a motor 4 is fixedly arranged outside the box body 1, and the output end of the motor 4 is fixedly connected to the rightmost rotating shaft;

[0036] A cleaning brush 21 is provided on the side of the feeding roller 2 for cleaning the surface of the material;

[0037] A water tank 5 is provided below the feed roller 2, and the lower end of the feed roller 2 is provided in the water tank 5. The water tank 5 is provided with a water inlet 51 and a water outlet 52, so as to facilitate timely cleaning and washing of the cleaning brush 21 on the feed roller 2;

[0038] A discharge port 13 is disposed on the right side of the box body 1 , and a discharge plate 11 is disposed between the discharge port 13 and the right end feed roller 2 .

[0039] Preferably, the feed roller 2 comprises a convex ring 22 and a concave ring 23, and the convex ring 22 and the concave ring 23 are alternately distributed along the radial direction of the feed roller 2, and the convex ring 22 of any feed roller 2 is engaged with the concave ring 23 of the adjacent feed roller 2;

[0040] The outer side of the convex ring 22 is covered with a cleaning brush 21 .

[0041] Preferably, a feeding channel 14 is provided in the box body 1, the upper end of the feeding channel 14 is fixedly connected to the lower end of the feed port 12, and the lower end of the feeding channel 14 is arranged above the feeding roller 2. By providing the feeding channel, dust can be avoided when materials are put into the box body 1.

[0042] Preferably, the water inlet 51 of the water tank 5 is arranged at the upper left end of the water tank 5 , and the water outlet 52 of the water tank 5 is arranged at the right bottom of the water tank 5 .

[0043] Preferably, the inner bottom of the water tank 5 is inclined and the left side is higher than the right side, so that the dust settled at the bottom can be discharged from the drain port 52.

[0044] Preferably, a high-frequency oscillator 53 is provided in the water tank 5, which accelerates the cleaning of the cleaning brush 21 of the feed roller 2 and improves the dust removal rate of the material through high-frequency oscillation of water.

[0047] The water tank 5 is provided with staggered baffles 54, which can allow the dust dropped by the cleaning brush 21 to slide along the baffles 54 to the bottom of the water tank, and the staggered arrangement can prevent the dust from floating up, thereby improving the cleaning efficiency of the cleaning brush 21 and thus improving the cleaning efficiency of the waste. The inner bottom of the water tank 5 is inclined and the left side is higher than the right side, so that the dust settled at the bottom can flow to the right side along the inclined angle to discharge the sewage and settled dust from the drain port 52.

[0048] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
