After the second motor 37 is started, the rotating plate 38 can be rotated, so that the cleaning brush 311 on the outer ring of the lower extension tube 39 cleans the soil residue stuck in the loading mechanism. At the same time, by starting the pump 314, the water in the water tank 313 can be pumped into the multiple lower extension tubes 39 through the water guide box 312, so that the water in the lower extension tubes 39 can be sprayed out through the water outlet 310 to clean the loading mechanism. In this way, after the device has been operated once, it can be cleaned without taking out the screening structure. When the cleaning is completed, the pump 314 is turned off and the multiple electric heating rods 315 are started, so that the electric heating rods 315 dry the inside of the loading mechanism to prevent the soil from sticking to the screening structure during subsequent processing.
