The crushing equipment for pet feed production according to claim 1, characterized in that: the collection mechanism (7) includes a base (71), and the base (71) is set on the right side of the crushing box (1) , the inside of the base (71) is provided with a chute (72), the inner wall of the chute (72) is slidably connected with a slider (73), and the top of the slider (73) is fixedly connected with a collection frame (74), A pull rod (75) is fixedly connected to the front of the collection frame (74), and a guide frame (76) is fixedly connected to the inner wall of the crushing box (1). 8. The crushing equipment for pet feed production according to claim 7, characterized in that: the inner wall shape of the chute (72) matches the outer shape of the slider (73), and the crushing box (1) right An opening matching the guide frame (76) is provided on the side, and the guide frame (76) is transparently opened so that the opening runs through the right side of the crushing box (1). 9. A crushing method for pet feed production according to claim 1, characterized in that: comprising the following steps: S1. Raw material processing First, the raw materials to be crushed are transported to the receiving area through unloading equipment or hoisting equipment, and the raw materials need to be fresh and dry before crushing, and then the raw materials are weighed according to the production formula of pet feed The equipment weighs different pet feed raw materials in proportion, and mixes them through the mixing equipment to ensure that the formula is accurate, and then the raw materials after proportioning can be transported to the inside of the crushing box (1); S2, raw material crushing When the remote is put into the crushing box (1), the motor (51) can be started to work at this time, and the motor (51) can drive the two crushing rollers (62) to rotate at the same time through transmission, and then the crushing of the remote can be realized. The purpose is to crush the raw material into a size suitable for processing, and the crushed raw material will fall down under the action of gravity; S3, raw material screening When the motor (51) is working, it will also drive the limit block (502) to reciprocate on the outer wall of the fixed rod (503) through the transmission, so that the reciprocating movement of the screening frame (4) can be realized, and the downward falling The raw materials can fall to the top of the screening frame (4) under the guidance of the guide plate (8), so as to achieve the purpose of reciprocating screening, and the raw materials that meet the size requirements will fall downward through the opening at the bottom of the crushing box (1). The raw materials that do not meet the size will fall to the inside of the collection frame (74) under the action of the inclined setting of the screening frame (4) and guide frame (76), so as to achieve the purpose of collection. The large particles and impurities in the raw materials are removed to achieve good processing quality, so as to achieve the purpose of crushing and screening. 10. A crushing method for pet feed production according to claim 9, characterized in that: in the step S1, in order to ensure the crushing effect and stable output, it is necessary to pay attention to the selection of the size of the crushing roller (62) and ensure that the equipment Keep it clean and well maintained, while the particle size of pet feed raw materials after crushing should be adjusted according to the needs of different pets.
