[0012] The beneficial effects of the utility model are as follows: when the machine is used, after the motor is turned on, the output end of the motor drives the transmission push rod to rotate, and the transmission push rod drives the connecting rod and the rotating shaft to rotate. At this time, the horizontal guide rod will slide along the internal circular groove of the connecting rod. Because of the effect of the horizontal spring, the front end of the rotating push assembly will not be damaged due to contact. When the rotating push assembly is working, it drives the rotating shaft to rotate, and at the same time drives the mounting plate to rotate. The cutting blade and the water spray bar installed on the mounting plate will rotate and work at the same time. At this time, the water in the water tank will flow into and spray out of the water spray bar through the holes on the mounting plate. At the same time, because of the effect of the protective ring, the water thrown out by the cutting assembly when working at high speed will adhere to the cutting blade under the effect of the protective ring, and complete the rapid cooling work. After the material enters the discharge plate through the feed pipe, it is squeezed and pushed by the transmission feed structure inside the feed pipe, and is sent out from the holes on the discharge panel and cut by the cutting assembly. At the same time, the material after cutting falls onto the vibrating screen plate at the bottom, and the cooled water falls through the holes on the vibrating screen plate. The cooled material is discharged through the discharge port along the vibrating screen plate for collection. BRIEF DESCRIPTION OF THE DRAWINGS
