[0007] In addition, in one example, the upper striking plate assembly 3 is L-shaped and is arranged on the upper wall and the part of the inner wall of the crushing cavity body 2 not covered by the bionic peripheral guard plate 5.

[0008] In addition, in one example, the diameter of the bionic convex ball 5-2 is D, m rows are uniformly distributed along the axial direction of the crushing cavity body 2, the spacing between each row is L2, n columns are sequentially arranged along the radial direction of the crushing cavity body 2, and the spacing between each column is L1.

The biomimetic convex spheres increase the randomness of material collisions between the biomimetic peripheral guard plates, thereby avoiding severe local wear. The biomimetic ribs can change the rebound direction of materials after colliding with the biomimetic peripheral guard plate, causing the materials to rebound towards the inlet, increasing the number of collisions and thus improving the crushing rate of the sand making machine. This achieves both increased crushing rate and improved wear resistance of the sand making machine. Attached Figure Description

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the drawings. However, those skilled in the art can understand that in the embodiments of the present application, many technical details are proposed in order to make the reader better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed by the present application can be implemented. The division of the following embodiments is for the convenience of description, and should not constitute any limitation on the specific implementation of the present application, and the embodiments can be combined and referred to each other without contradiction.

[0022] In one embodiment, the structure of the bionic sand making machine crushing cavity assembly is shown in Figure 1 The figure shows the following: 1-main shaft; 2-crushing cavity body; 3-upper impact plate assembly; 4-rotor; 5-bionic peripheral guard plate, 5-1-mounting buckle; 5-2-bionic convex ball; 5-3-bionic rib; 6-rotor fixing device; 7-main shaft fixing device; 8-screw. Figure 2As shown, including installation buckle 5-1, biomimetic convex ball 5-2, biomimetic rib 5-3, biomimetic convex ball 5-2 is a half spherical structure with different sizes, and biomimetic rib 5-3 is a triangular prism structure; Biomimetic rib 5-3 is arranged on the side of biomimetic peripheral guard plate 5 facing main shaft 1, in this embodiment, the side of biomimetic peripheral guard plate 5 facing main shaft 1 is called front side, biomimetic convex ball 5-2 is arranged on both sides of biomimetic peripheral guard plate 5, which is called side in this embodiment, and installation buckle 5-1 is arranged on the side of biomimetic peripheral guard plate 5 away from main shaft 1, which is called back side in this embodiment. Biomimetic rib 5-3 can change the rebound direction of the material after colliding with the biomimetic peripheral guard plate, so that the material rebounds to the inlet direction, increases the collision times of the material, and improves the crushing rate of the sand making machine. In this way, the crushing rate of the sand making machine is improved, and the wear resistance is also improved. The upper impact plate assembly 3 is uniformly distributed on the upper wall of the crushing cavity body 2. The biomimetic peripheral guard plate 5 is distributed in 2-4 layers along the axial direction on the inner wall of the crushing cavity body 2, and each layer is uniformly distributed in 16-28, such as Figure 3 As shown, the number of settings can be adjusted in different actual application scenarios, which is not limited here.

[0023] In one example, the upper impact plate assembly 3 is L-shaped, arranged on the upper wall and the part of the inner wall of the crushing cavity body 2 not covered by the biomimetic peripheral guard plate 5. The upper impact plate assembly 3 is arranged to protect the area of the inner wall of the crushing cavity not covered by the biomimetic peripheral guard plate 5 from being impacted by the material, reduce wear and tear, and improve the service life of the crusher.

[0024] In one example, the diameter of the biomimetic convex ball 5-2 is D, which is uniformly distributed in m rows along the axial direction of the crushing cavity body 2, and the spacing between each row is L2; arranged in n columns in turn along the radial direction of the crushing cavity body 2, and the spacing between each column is L1, such as Figure 4 As shown;

[0025] In n columns of biomimetic convex balls 5-2, the diameter D of each column decreases in turn in the radial direction of the crushing cavity body 2, wherein m and n are integers greater than or equal to 1. Because the biomimetic convex ball 5-2 is a hemispherical type, a large number of random rebound directions will appear after the material with different incoming angles collides with its spherical surface. And the diameter of the biomimetic convex ball 5-2 decreases in turn in the radial direction of the crushing cavity, the spherical surface radian is different in the radial direction, and a large number of random rebound directions will also appear after the material with the same incoming angle collides with it. A large number of random rebound directions will increase the randomness of the material colliding with the biomimetic peripheral guard plate 5 next time, and the specific collision diagram is as follows Figure 5As shown in the figure, the bionic convex ball 5-2 increases the randomness of the material collision between the bionic peripheral guard plate 5, thereby avoiding local severe wear. In addition, the bionic convex ball 5-2 close to the front of the bionic peripheral guard plate 5 is set to the maximum diameter because it is closest to the rotor and has a greater probability of being impacted, and increasing the diameter can increase its wear resistance. The diameter becomes smaller and smaller because the probability of being impacted is smaller and smaller, and it is unnecessary to make a uniform large-diameter convex ball, which further reduces the production cost.

[0026] In one example, the bionic rib 5-3 is a right triangular prism structure, one right side is vertically attached to the side of the bionic peripheral guard plate 5 facing the main shaft 1, and the included angle angle β facing the main shaft 1 is as shown in the figure. Figure 4 K bionic ribs 5-3 are arranged in sequence along the axial direction of the crushing cavity body 2 with a spacing L3, wherein K is an integer greater than or equal to 1. The bionic rib 5-3 can change the rebound direction of the material after colliding with the bionic peripheral guard plate 5, make the material rebound to the inlet direction, increase the collision times of the material, and thereby improve the crushing rate of the sand making machine.

[0027] In one example, the thickness of the bionic peripheral guard plate 5 is L, the side length of the bionic peripheral guard plate 5 is Z, L1=0.1~0.15Z, L2=0.1~0.25L, and D=0.1~0.5L1. The inclined surface of the bionic rib 5-3 right triangular prism structure faces the material inlet direction in the crushing cavity body 2. The height of the bionic rib 5-3 is H, the included angle angle β is in the range of 45°~60°, H=0.1~0.25L, and L3=0.1~0.25L. According to the above rules, the parameters of each part of the bionic peripheral guard plate 5 are set, which can ensure that the wear resistance and the rebound efficiency are at a high level.

[0028] Those skilled in the art can understand that the above embodiments are specific examples for implementing the present application, and in actual application, various changes can be made in form and details without departing from the spirit and scope of the present application.
