For example, silicon carbide powder is coated on the inner wall of turbine impeller or cylinder body by special process to make high-grade refractory materials, which are resistant to thermal shock, small in size, light in weight, high in strength and good in energy saving. After silicon carbide is prepared and made into corresponding products, it needs to be crushed by a pulverizer, and the crushed silicon carbide is then formed.

In the initial state, the crushing blade 12 is at the bottom position of the crushing barrel 03, and then the upper cover 04 is opened, and silicon carbide is placed in the crushing barrel 03. The crushing shaft 11 and the crushing blade 12 are driven to rotate by the driving assembly 3, so that the silicon carbide in the crushing barrel 03 is crushed.

[0039] Reference Figure 3 and Figure 4The driving assembly 3 includes a driving motor fixed in the mounting shell 02, a driving rod 32 fixed on the output shaft of the driving motor, and a moving rod 33 slidably connected to the driving rod 32, one end of the moving rod 33 is fixedly mounted on the crushing shaft 11; a sliding groove 05 is provided on the driving rod 32, the sliding groove 05 is arranged along the length direction of the driving rod 32, and the moving rod 33 is slidably connected in the sliding groove 05.

One end of the abutment spring 43 is fixed on the bottom wall of the crushing barrel 03, and the other end is fixed on the mounting sleeve 41. Then, when the abutment shaft 42 moves from the highest point 23 to the lowest point 24, the abutment spring 43 pushes the abutment shaft 42 to always abut against the control surface 22, so that the abutment shaft 42 can move up and down better.

The adjusting assembly 5 includes an adjusting plate 51 fixed on the control ring 21 and an adjusting screw 52 rotatably connected to the mounting shell 02. The adjusting screw 52 is passed through the adjusting plate 51 and is threadedly connected to the adjusting plate 51. At this time, by rotating the adjusting screw 52, ​​the position of the adjusting plate 51 and the control ring 21 can be adjusted, and then the moving height of the crushing blade 12 can be adjusted.

[0044] Reference Figure 3 , Figures 6 to 8 A toggling assembly 6 for scooping up the material under the crushing blade 12 is provided on the crushing shaft 11. When the crushing blade 12 moves downward from the highest position, the toggling assembly 6 is arranged below the crushing blade 12. The material under the crushing blade 12 is scooped up by the toggling assembly 6. At this time, a space is dug out in the material under the crushing blade 12. Since the crushing blade 12 rotates at a fast speed, the crushing blade 12 can be placed in the dug out space. Then, in the process of the crushing blade 12 moving downward, the obstruction of the material to the crushing blade 12 is reduced, so that the crushing blade 12 can move downward better.

[0045] Reference Figure 3 , Figures 6 to 8 The toggle assembly 6 includes a moving block 61 slidably connected to the crushing shaft 11, a toggle plate 62 fixed to the moving block 61, and a return spring 63 fixed to the moving block 61. A mounting groove 9 is provided on the crushing shaft 11, the moving block 61 is slidably connected in the mounting groove 9, and the return spring 63 is also arranged in the mounting groove 9, one end of the return spring 63 is fixed to the moving block 61, and the other end is fixed to the mounting groove 9; in order to better enable the toggle plate 62 to dig up the material, in this embodiment, the toggle plate 62 is tilted. In addition, in this embodiment, two toggle plates 62 are provided, and the two toggle plates 62 are arranged on the same diameter of the crushing barrel 03, so that the material can be better dug up during the downward movement of the crushing blade 12.

[0046] Reference Figure 3 , Figures 6 to 8 A clearance groove 91 is provided on the crushing shaft 11, and the clearance groove 91 is connected to the mounting groove 9, and the toggle plate 62 is slidably connected in the clearance groove 91. Since two toggle plates 62 are provided, in this embodiment, two clearance grooves 91 are also provided, and the two clearance grooves 91 correspond to the two toggle plates 62 one by one, and then two elastic bands (not shown in the figure) are provided in each clearance groove 91, and the toggle plate 62 is located between the two elastic bands, one end of the elastic band above the toggle plate 62 is fixed to the top wall of the clearance groove 91, and the other end is fixed to the upper surface of the toggle plate 62, and one end of the elastic band below the toggle plate 62 is fixed to the bottom wall of the clearance groove 91, and the other end is fixed to the lower surface of the toggle plate 62.

[0047] Reference Figure 3 , Figures 6 to 8 A partition net 7 is arranged in the crushing barrel 03, a material storage chamber 71 is arranged below the partition net 7, and a baffle 72 is arranged in the material storage chamber 71, and the baffle 72 is arranged at an angle. In addition, a discharge pipe 73 is arranged at the lowest point of the baffle 72, and the discharge pipe 73 is fixed on the crushing barrel 03; in the process of crushing materials, since the partition net 7 is arranged below the crushing blade 12, the crushed material will fall into the material storage chamber 71 through the partition net 7, and then under the action of the baffle 72, the crushed material will be directly discharged from the discharge pipe 73. At this time, the material above the partition net 7 is reduced, which can better enable the crushing blade 12 to crush the material, thereby increasing the crushing speed of the material. In addition, since the material can be discharged from the discharge pipe 73 after being crushed, the purpose of crushing and discharging at the same time can be achieved. At the same time, the crushing blade 12 can move up and down, and it is also convenient for the material below the crushing blade 12 to be discharged through the discharge pipe.

[0048] In the initial state, under the action of the abutment spring 43, the crushing blade 12 is at the lowest position in the crushing barrel 03, and the abutment shaft 42 abuts against the lowest point 24 on the control surface 22. At this time, the lower end surface of the toggle plate 62 abuts against the partition net 7, and the return spring 63 is in a compressed state. Then, when rotating, the toggle plate 62 can scrape the material on the partition net 7 to make the crushed material fall faster; in the process of the control surface 22 pushing the crushing shaft 11 to move upward, the crushing blade 12 and the toggle plate 62 also move upward at the same time, and then the toggle plate 62 and the upper surface of the partition net 7 are no longer abutted. At this time, under the action of the return spring 63, the toggle plate 62 moves downward, and the toggle plate 62 is in the crushing state. Below the crushing blade 12, during the rotation of the crushing blade 12, the toggle plate 62 scoops up the material below the crushing blade 12, which can make the crushing speed faster. Then, during the downward movement of the crushing blade 12, since the toggle plate 62 is below the crushing blade 12 and the toggle plate 62 is tilted, during the horizontal rotation, the material will be shoveled and moved upward in the inclined direction. During the upward movement of the shoveled material, a space will be formed behind the toggle plate 62. Then, during the process of the abutment spring 43 pulling the crushing blade 12 to move downward, the crushing blade 12 can move into the space shoveled by the toggle plate 62. At this time, the material can be better moved, which is convenient for the crushing blade 12 to move downward.

[0049] Reference Figure 3 , Figures 6 to 8A pushing assembly 8 is provided on one of the toggle plates 62. The pushing assembly 8 is used to push the bulk material to move to the middle, so that the material crushing effect can be better. The pushing assembly 8 includes a pushing net 81 and a connecting net 82. The pushing net 81 is fixedly connected to the toggle plate 62. Two connecting nets 82 are provided. The two connecting nets 82 are fixedly connected to the two ends of the pushing net 81. At this time, the entire pushing assembly 8 is a C-shaped structure. The mesh sizes of the pushing net 81, the connecting net 82 and the partition net 7 are the same. Then, when the crushing shaft 11 drives the toggle plate 62 to rotate, the toggle plate 62 can drive the pushing net 81 and the connecting net 82 to rotate. Then, under the action of the pushing net 81, the crushed material will enter between the pushing net 81 and the inner wall of the crushing barrel 03, and the pushing net 81 will push the bulk material to move to the middle, so that the crushing blade 12 can better crush the material.

[0050] The implementation principle of the silicon carbide production raw material crushing equipment of the embodiment of the present application is as follows: when crushing silicon carbide, first open the upper cover 04, put the silicon carbide into the crushing barrel 03, cover the upper cover 04, and then drive the driving rod 32 to rotate through the driving motor. During the rotation of the driving rod 32, the moving rod 33, the crushing shaft 11 and the crushing blade 12 will be driven to rotate, and the material will be crushed by the crushing blade 12. During the rotation of the crushing shaft 11, the abutment shaft 42 will move up and down on the control surface 22, thereby driving the crushing blade 12 to move up and down in the crushing barrel 03, and then the material in the crushing barrel 03 will be crushed. Materials at different heights are crushed, and during the crushing process, the crushed materials will enter the storage chamber 71 and then be discharged through the discharge pipe 73. At this time, the material in the crushing barrel 03 will become less, and the crushing blade 12 can better crush the material during its rotation, thereby increasing the crushing speed of the material. In addition, in the process of the crushing blade 12 moving downward, the toggle plate 62 will shovel up the material under the crushing blade 12, and at the same time, the material that meets the requirements will enter the storage chamber 71, and then the material under the crushing blade 12 will be reduced, which makes it more convenient for the crushing blade 12 to move downward.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
