The crushing blades 303 on the cutter disc 302 rotate at high speed to crush the feed. During the crushing process, the scraper 304, which is in contact with the screen 305, continuously cleans and squeezes the feed crushed to the appropriate mesh size out of the screen 305, preventing the feed from clogging the screen 305 and ensuring that the crushed feed can pass smoothly through the screen 305. Under the action of gravity, the crushed feed falls into the machine casing 2. On the inclined guide plate 801, the feed slides down to the discharge port 802 at the bottom of the casing 2. By pulling the handle 805 on the valve plate 804, the sliding of the valve plate 804 on the discharge hopper 803 is controlled, thereby controlling the discharge speed and amount, so that the crushed feed is discharged through the discharge hopper 803. After the equipment is used up, the power of the first motor 402 and the second motor 703 is turned off, the opening and closing structure 6 is opened, that is, the screw 603 is rotated to separate the nut 605 from the locking block 604, the machine cover 509 is opened, the abutment ring 510 on the machine cover 509 no longer abuts the cover plate 503, the cover plate 503 is slid off the screen 305, the fixing rod 506 is separated from the positioning hole 505, the screen 305 is taken out from the mounting groove 502, the screen 305 is disassembled for cleaning or replacement, which improves the installation and disassembly efficiency of the screen 305, facilitates the replacement of screens 305 with different mesh sizes, and improves the fineness of crushing.
