5. The processing method of a feed processing device for animal husbandry according to claim 4, characterized in that: The steps include: Step 1: First, the lower extrusion barrel in the extrusion structure (1) is supported and placed; then, after the equipment is powered on, the material is poured into the feed barrel (17), and the material is transported to the upper extrusion barrel (13) through the feed barrel (17); Step 2, then by controlling the first motor (84) on the support plate (82) in the conveying assembly (18), through the meshing transmission of the two bevel gears (85), the spiral conveying rod (83) is driven to rotate with the aid of the shaft frame (81) and the bearings of the layering platform (11), driving the material to move toward the bottom of the upper extrusion barrel (13), passing the material through the first extrusion hole of the layering platform (11) and the second extrusion hole of the regulating plate (36) in the regulating structure (3), so that the material is extruded through the first extrusion hole and the second extrusion hole; Step 3: While the second step is being performed, the second motor (21) in the cutting structure (2) is controlled to drive the first cutting frame (23) and the tray (26) to rotate, and the extruded material is cut by the first cutting frame (23) to perform granulation; Step 4: before processing and use, according to different use requirements, the rocker (34) in the regulating structure (3) drives the wheel shaft (33) to rotate between the wheel frames (32) on both sides of the collar (31), drives the gear (35) to rotate, and drives the gear (35) and the rack of the regulating plate (36) to engage and contact the transmission, drives the regulating plate (36) to move in the layering table (11), and then makes the first extrusion hole and the second extrusion hole staggered relative to each other, adjusts the hole size, adjusts the diameter of the material, and after adjustment, squeezes the regulating plate (36) through the downward pressing screw (12) to limit the position; Step 5: By controlling the electric push rod (27) to extend and retract, the second cutting frame (24) and the third cutting frame (25) are driven to move up and down, and cooperate with the first scraper on the first cutting frame (23) to fit under the layered plate, and cut the extruded material by rotation; since the rotation speed of the shaft (22) is constant, the first cutting frame (23) and the second cutting frame (24) are increased or decreased to increase the number of scrapers, that is, increase the cutting frequency and reduce the cutting length.
