[0002] Silicon carbide is an inorganic substance, which is smelted at high temperature in an electric resistance furnace with raw materials such as quartz sand, petroleum coke (or coal coke), and wood chips (salt needs to be added when producing green silicon carbide). Silicon carbide is a semiconductor and exists in the form of an extremely rare mineral moissanite in nature. The raw materials smelted from silicon carbide need to be further crushed into particles before they can be used. Currently, crushers are mostly used to complete this task, and they have the advantages of simple operation, stable structure, and good use effect in actual use.

When in actual use, the silicon carbide raw materials are crushed through the feeding port. After the silicon carbide raw materials are crushed, the unqualified particles will be blocked by the sieve plate and slide into the material returning cylinder, and are pushed by the screw rod into the feeding port for re-crushing, and the qualified particles fall from under the sieve plate and are discharged from the discharging port.

[0004] In the above-mentioned utility model, the silicon carbide raw materials are directly put into the interior of the machine body, and the rotating driving crushing wheel and driven crushing wheel can crush the silicon carbide raw materials, but there is no protective structure, and the debris generated by crushing will burst out of the interior of the machine body, increasing the subsequent cleaning workload. Seriously, the burst-out debris may injure the operating workers, reducing the use safety of this utility model.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present utility model provides a new type of silicon carbide raw material crusher, which has the following beneficial effects:

[0018] (1). The utility model adopts a feeding square pipe. When actually using the novel silicon carbide raw material crusher, the operator needs to put the silicon carbide raw material into the inside of the feeding square pipe. After that, a plurality of inclined guide plates will guide the silicon carbide raw material, and the silicon carbide raw material will finally fall into the inside of the machine body. Two inclined blocks will guide the silicon carbide raw material to make it enter between two crushing rolls. By using the control panel, the servo motor and the driving motor are made to work. The output end of the servo motor will drive a group of crushing rolls on the left side and the first gear to rotate.

When the size between this group of guide plates and the inner wall of the machine body increases, the larger silicon carbide raw material can pass through. At this time, this group of guide plates can be released. Two telescopic springs on the same side are pulled by their own elastic forces and will pull two fixing plates on the same side to make this group of guide plates reset. Two metal protrusions on the same side play a role in limiting this group of guide plates. The use of the other groups of guide plates can be obtained in the same operation. The crushed silicon carbide raw material can fall on the screen. The silicon carbide raw material that meets the size can pass through the screen, and the silicon carbide raw material that does not meet the size can enter the inside of the conveying cylinder through the connecting pipe. The output end of the driving motor can drive the auger to rotate. The rotating auger can push the silicon carbide raw material that does not meet the size. This part of the silicon carbide raw material can pass through the discharge pipe and fall back into the inside of the feeding square pipe for re-crushing work. By setting the feeding chamber square pipe with a protective structure, it can prevent the generated debris from bursting out of the machine body, improving the safety of using the novel silicon carbide raw material crusher.

[0019] (2). The utility model adopts a dust collection box. According to the above operation, it can be known that by using the control panel, the driving motor can be made to work. The output end of the driving motor can drive the auger to rotate. The auger can drive the fan blades to rotate through the extension shaft. The rotating fan blades can suck air and dust through the dust inlet into the inside of the dust collection box. The air can pass through the filter bag and can be removed through the intercepting filter screen. The dust will be left by the filter bag. The mounting plate plays a role in mounting the filter bag. By setting the dust collection box, the dust removal work can be completed without adding electric dust removal equipment, improving the practicality of using the novel silicon carbide raw material crusher.

[0036] Working principle:

[0037] When actually using the new type of silicon carbide raw material crusher, the operator needs to put the silicon carbide raw materials into the interior of the feeding square pipe 11. After that, multiple inclined guide plates 14 will guide the silicon carbide raw materials, and the silicon carbide raw materials will finally fall into the interior of the machine body 1. Two inclined blocks 2 will guide the silicon carbide raw materials to make the silicon carbide raw materials enter between the two crushing rollers 3. By using the control panel, the servo motor and the driving motor 10 are made to work. The output end of the servo motor will drive the left set of crushing rollers 3 and the first gear 4 to rotate. The rotating first gear 4 will drive the right set of crushing rollers 3 to rotate. The two rotating crushing rollers 3 will crush the silicon carbide raw materials. The multiple guide plates 14 can prevent the generated silicon carbide raw material particles from moving out of the feeding square pipe 11. When there are larger-sized silicon carbide raw materials above the multiple guide plates 14, the operator pulls the two fixing plates 15 on the same side by hand, which can drive a set of guide plates 14 on the same side to move. When the dimension between this set of guide plates 14 and the inner wall of the machine body 1 increases, the larger silicon carbide raw materials can pass through. At this time, this set of guide plates 14 can be released. The two telescopic springs 17 on the same side, under the action of their own elastic forces, will pull the two fixing plates 15 on the same side to make this set of guide plates 14 reset. The two metal protrusions 16 on the same side play a role in limiting this set of guide plates 14. The use of the other sets of guide plates 14 can be obtained by the same operation. The crushed silicon carbide raw materials can fall on the screen 6. The silicon carbide raw materials that meet the dimensions can pass through the screen 6, and the silicon carbide raw materials that do not meet the dimensions can enter the interior of the conveying cylinder 7 through the connecting pipe 8. The output end of the driving motor 10 can drive the auger 9 to rotate. The rotating auger 9 can push the silicon carbide raw materials that do not meet the dimensions. This part of the silicon carbide raw materials can pass through the discharge pipe 18 and fall back into the interior of the feeding square pipe 11 for re-crushing work. Through the set feeding chamber square pipe, with a protective structure, it can prevent the debris generated by crushing from bursting out of the machine body 1, improving the safety of using the new type of silicon carbide raw material crusher. At the same time, according to the above operations, by using the control panel, the driving motor 10 can be made to work. The output end of the driving motor 10 can drive the auger 9 to rotate. The auger 9 can drive the fan blade 21 to rotate through the extension shaft 20. The rotating fan blade 21 can suck the air and dust through the dust inlet 24 into the interior of the dust collection box 12. The air can pass through the filter bag 23 and can be removed through the intercepting filter screen 19. The dust will be left by the filter bag 23. The mounting plate 22 plays a role in mounting the filter bag 23. Through the set dust collection box 12, the dust removal work can be completed without adding electric dust removal equipment, improving the practicality of using the new type of silicon carbide raw material crusher.
