[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present invention, many technical details are proposed in order to enable the reader to 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 in the present invention 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 invention. The various embodiments can be combined and referenced with each other without contradiction.

[0022] In one embodiment, the schematic diagram of the crushing chamber assembly structure of the bionic sand making machine is as follows: Figure 1 As shown, it includes a main shaft 1, a crushing chamber body 2, an upper striking plate assembly 3, a rotor 4, a bionic peripheral guard plate 5, a rotor fixing device 6, a main shaft fixing device 7, and a screw 8; the crushing chamber body 2 is a hollow cylindrical body, the main shaft fixing device 7 is installed on the axis of the crushing chamber body 2, the main shaft 1 is fixed on the axis of the crushing chamber body 2 through the main shaft fixing device 7, the rotor 4 is fixedly connected to the main shaft 1 through the rotor fixing device 6 and the screw 8, N bionic peripheral guard plates 5 are evenly distributed along the circumferential direction on the inner wall of the crushing chamber body 2, and M upper striking plate assemblies 3 are evenly distributed on the upper wall of the crushing chamber body 2, wherein M and N are integers greater than or equal to 1; the schematic diagram of the bionic peripheral guard plate 5 is as shown Figure 2As shown, it includes a mounting buckle 5-1, a bionic convex ball 5-2, and a bionic rib 5-3. The bionic convex ball 5-2 is a hemispherical structure of different sizes, and the bionic rib 5-3 is a triangular prism structure; the bionic rib 5-3 is arranged on the side of the bionic peripheral guard plate 5 facing the main shaft 1. In this embodiment, the side of the bionic peripheral guard plate 5 facing the main shaft 1 is called the front side, the bionic convex ball 5-2 is arranged on both sides of the bionic rib 5-3, which is called the side in this embodiment, and the mounting buckle 5-1 is arranged on the side of the bionic peripheral guard plate 5 facing away from the main shaft 1, which is called the back side in this embodiment. The bionic rib 5-3 can change the rebound direction of the material after the collision with the bionic peripheral guard plate, so that the material rebounds toward the inlet direction, increases the number of collisions of the material, and thus improves the crushing rate of the sand making machine. In this way, it is achieved that the crushing rate of the sand making machine can be improved while also increasing its wear resistance. The upper striking plate assembly 3 is evenly distributed on the upper wall of the crushing chamber body 2 16 to 28. The bionic peripheral guard plates 5 are distributed in 2 to 4 layers along the axial direction on the inner wall of the crushing chamber body 2, and each layer has 16 to 28 uniformly distributed circumferentially. Figure 3 As shown, in different practical application scenarios, the number of settings can be adjusted and is not limited here.

[0023] In one example, the upper striking plate assembly 3 is L-shaped and is arranged on the upper wall and the inner wall of the crushing chamber body 2 that are not covered by the bionic peripheral guard plate 5. The upper striking plate assembly 3 is to protect the area of ​​the inner wall of the crushing chamber that is not covered by the bionic peripheral guard plate 5 from being impacted by materials, reduce wear, and increase the service life of the crusher.

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

[0025] Among the n rows of bionic convex balls 5-2, the diameter D of each row decreases arithmetic in the radial direction of the crushing chamber body 2, wherein m and n are integers greater than or equal to 1. Because the bionic convex ball 5-2 is hemispherical, a large number of random rebound directions will appear after the materials with different incoming angles collide with its spherical surface. In addition, the diameter of the bionic convex ball 5-2 decreases in the radial direction of the crushing chamber, and the spherical curvature is different in the radial direction. A large number of random rebound directions will increase the randomness of the next collision of the material with the bionic peripheral guard plate 5. The specific collision diagram is shown in the figure. Figure 5As shown. It can be seen that the bionic convex ball 5-2 increases the randomness of the collision of materials between the bionic peripheral guard plates 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 have the largest diameter because it is closest to the rotor and has a greater probability of being impacted. Increasing the diameter can increase its wear resistance. The diameter at the back is getting smaller and smaller because the probability of being impacted is getting smaller and smaller. It is unnecessary to make a uniform large-diameter convex ball, which further reduces production costs.

[0026] In one example, the bionic rib 5-3 is a right-angled triangular prism structure, and one right-angled side surface is perpendicular to the axis and attached to the side of the bionic peripheral guard plate 5 facing the main axis 1, and the angle β toward the main axis 1 is, such as Figure 4 As shown in the figure, K bionic ribs 5-3 are arranged in sequence along the axial direction of the crushing chamber body 2, with a spacing of L3, where K is an integer greater than or equal to 1. The bionic ribs 5-3 can change the rebound direction of the material after colliding with the bionic surrounding guard plate 5, so that the material rebounds toward the inlet direction, increasing the number of collisions of the material, thereby improving 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, D=0.1~0.5L1. The inclined surface of the right-angled triangular prism structure of the bionic rib 5-3 faces the material inlet direction in the crushing chamber body 2. The height of the bionic rib 5-3 is H, the angle β ranges from 45° to 60°, H=0.1~0.25L, L3=0.1~0.25L. By setting the parameters of each part of the bionic peripheral guard plate 5 according to the above rules, it can be ensured that the wear resistance and rebound efficiency are at a high level.

[0028] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
