[0034] In addition, the belt assembly 2124 includes a transmission wheel fixedly installed on the outside of the shaft 2122 and the two rotating rods 2123. The outer surfaces of the upper and lower transmission wheels are connected with transmission belts. When the shaft 2122 rotates, under the transmission action of the transmission wheel and the transmission belt, the shaft 2122 will drive the two rotating rods 2123 to rotate. The shaft 2122 can drive the two rotating rods 2123 to rotate through the transmission wheel and the transmission belt.

[0035] It should be noted that the transmission assembly 2125 includes a driving bevel gear fixedly mounted on the front of the two rotating rods 2123, and a driven bevel gear meshing with the driving bevel gear is fixedly mounted on the outer sides of the two rotating shafts 203.

[0049] Among them, the mud cake is crushed by two crushing plates 209, so that the volume of the mud cake becomes smaller, so that it falls from the drop hole 211 and is crushed. At the same time, the two abutment plates 207 will squeeze the two compression springs respectively. When the two eccentric wheels 204 continue to rotate, under the action of the rebound force of the compression springs, the two crushing plates 209 will move to the opposite side. Through the continuous rotation of the two eccentric wheels 204 and the rebound force of the two compression springs, the two crushing plates 209 can continue to crush the mud cake, making the volume of the mud cake smaller, thereby facilitating the subsequent crushing of the mud cake.
