[0025] Specific implementation method: by opening the valve on the feed pipe 10, the granulated humic acid urea fertilizer is transported to the inside of the extrusion barrel 4, the electric heating wire layer 12 is started to heat the inside of the drying bin 3, and the servo motor 96 output end of the lifting and extruding assembly 9 is started to rotate the switch clockwise, so that the driving screw 97 can be driven to rotate clockwise. Since the limiting telescopic rod 93 has a limiting effect on the threaded sleeve 98, the mounting seat 92 and the extrusion seat 91, when the driving screw 97 rotates forward and reversely, the threaded sleeve 98 can be driven to move up and down, so that the extrusion seat 91 can be driven to move up and down in the extrusion barrel 4 through the mounting seat 92.
