The utility model is provided with a main body, a rotating shaft, a crushing rod and a cutting tooth. The cutting teeth and the crushing teeth can divide and crush the material, the first filter plate can filter the large volume of the material, improve the degree of the material crushing by the main body, solve the problem that the existing equipment cannot fully crush the material, which easily leads to the large volume of the material, and some existing equipment is easily blocked by the material, reducing the practicality of the equipment.

[0004] The above-mentioned prior art performs multi-stage crushing of materials. Although the crushing fineness of the materials at the lower position is high, the volume of the materials filtered and intercepted at the upper position is still relatively large, resulting in low overall crushing fineness of the materials. It is not convenient to perform step-by-step fine crushing as the crushing volume of the materials changes. Moreover, when the materials are unloaded, they are accumulated in one place for feeding, and the crushing blades are subjected to greater force, which is easy to damage the crushing blades, and the crushing efficiency of the materials becomes lower. Therefore, we propose a feed raw material crusher to solve the above-mentioned problems. Summary of the invention

[0010] Preferably, the feeding hopper is a funnel-shaped structure, and the vertical center line of the feeding hopper and the vertical center line of the crusher housing coincide with each other. This design can use the feeding hopper to concentrate the feed raw materials into the feeding pipe, and when the feeding pipe rotates, ensure that the lower end of the feeding pipe is continuously aligned between the inner crushing roller and the outer crushing cover.

[0011] Preferably, the upper end of the feeding pipe can rotate outside the feeding pipe, and the middle section of the feeding pipe is an inclined structure. This design can ensure that the feed raw materials are smoothly transported in the feeding pipe to avoid blockage or leakage.

This design can use the outer crushing knife and the inner crushing knife to quickly crush the feed.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The feed raw material crusher drives the feed pipe to rotate through the rotating rod, so that the feed pipe changes its position around the vertical center line of the crusher shell, ensuring that the lower end of the feed pipe continues to face the area between the inner crushing roller and the outer crushing cover, and synchronously changes the position of the feed pipe facing the area between the inner crushing roller and the outer crushing cover, so that the feed raw materials are put into different positions between the inner crushing roller and the outer crushing cover for crushing operation, avoiding the accumulation and crushing of the feed raw materials, and can crush the feed raw materials quickly, evenly and comprehensively, and reduce the force on the crushing knife and the damage to the crushing knife;

[0016] (2) The feed raw material crusher drives the inner crushing roller to rotate through the rotating rod to crush the falling feed raw materials. The inclined crushing cover is used to slow down the falling speed of the feed raw materials, leaving time for crushing them. With the reduction of the gap between the inner crushing roller and the outer crushing cover, all the incoming feed raw materials can be crushed step by step. BRIEF DESCRIPTION OF THE DRAWINGS
