[0002] In the building materials manufacturing industry, hollow bricks are a widely used building material. The raw material crushing process in their production process has an important impact on the quality and production efficiency of the final product. Traditional hollow brick raw material crushing equipment often uses a single crushing method, such as crushing only by mechanical extrusion or impact. This method has certain limitations when processing raw materials of different hardness, particle size and shape, and often cannot achieve ideal crushing effects.

[0046] The working principle and use process of the present invention:

[0047] In the hollow brick raw material crushing device, the hollow brick crushing raw material is introduced through the feed port 210, and the crushing raw material is sheared and crushed by the relative crushing rollers 220 in the pre-crushing tube cabin 200 for initial crushing, so as to ensure that the material particles can be introduced between the rotating grinding plate 410 and the moving grinding plate 420 through the feed port 411, and the fixed guide seat 310 is driven by the motor inside the driving chassis 110 to rotate at a uniform low speed; at the same time, the motor at the bottom of the crushing cabin 100 drives the dynamic energy conversion through the transmission gear ring 321 The ring 330 rotates synchronously, but when material enters between the rotating grinding disc 410 and the dynamic grinding disc 420, the top surface of the material contacts the bottom surface of the rotating grinding disc 410, and the bottom surface abuts against the surface of the dynamic grinding disc 420 and synchronously presses the dynamic grinding disc 420 downward, and the spring 341 pulls the grinding disc 420 downward, so that the bottom surface of the dynamic grinding disc 420 abuts against the teeth 421 and the top surface of the dynamic energy conversion ring 330, and the dynamic grinding disc 420 reciprocates up and down under the rotation of the dynamic energy conversion ring 330, so as to crush the material between the rotating grinding disc 410 and the dynamic grinding disc 420;

[0048] At the same time, the universal support of the grinding ball convex 430 can be realized inside the fixed guide seat 310 through the star ring 311 and the ball 313, so that the grinding ball convex 430 can be tilted in any direction, and the distance with the bottom surface of the rotating grinding plate 410 is enlarged to accommodate larger materials to enter. Under the tilting effect of the grinding ball convex 430, the crushed materials can be quickly separated from the surface of the grinding ball convex 430. On the surface of the bearing ring seat 320, the dynamic energy conversion ring 330 is actively rotated to realize the impact movement of the dynamic grinding plate 420 under the rotating grinding plate 410. Under the reciprocating impact effect, the relative rotation of the rotating grinding plate 410 is coordinated to achieve the dual crushing effect of grinding and impact of the raw materials, thereby improving the crushing degree and working efficiency.
