[0099] When the motor is started, the filter core can be driven to rotate together, and the filter material adhered to the surface of the filter core can be scraped off through the contact between the material guide scraper and the surface of the filter core. When the motor is started, the third gear can be intermittently rotated by the driving of the driving block, so that the material guide scraper can swing under the cooperation of the first spring, thereby achieving the effect of conveniently guiding the material and avoiding the problem of adhering the filter material. At the same time, the first eccentric wheel, the second eccentric wheel and the linkage rod are linked to drive the shaft rod to reciprocate, thereby driving the knocking ball at the end of the traction rope to knock the lower surface of the material guide scraper, so as to shake it and make it more convenient to discharge the material.

[0100] The filter core is convenient to disassemble and install. By pulling the clamping plate, the second clamping block is separated from the notch, at this time the round rod can slide along the inside of the filter core, so as to separate from the first clamping block, at this time the filter core is convenient to disassemble. After the filter core is installed, the first clamping block can be tightly clamped in the notch under the extrusion and pulling of the second spring, so that the motor can drive the filter core to rotate after being started.

[0101] The above is the preferred embodiment of the application. It should be noted that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles described in the application, and these improvements and refinements should also be regarded as the protection scope of the application.
