[0028] Embodiment
[0029] Refer to Figures 1 - 4, the present utility model provides a technical solution: a mechanical crusher, which includes a box body 1 and a material jamming prevention mechanism 3, and a control motor 2 is installed outside the box body 1. The material jamming prevention mechanism 3 includes a round roller 31, the round roller 31 is rotatably installed inside the box body 1, and a material lifting plate 311 is fixedly installed on the outer surface of the round roller 31. A rotating rod 32 is fixedly installed inside the round roller 31 and extends to the outside of the box body 1, and a linkage wheel 321 is fixedly installed at the outer end of the rotating rod 32. A sliding plate 33 is fixedly installed at the position of the inner wall of the box body 1, and the sliding plate 33 is arranged at a position on one side of the round roller 31.
[0030] In a preferred embodiment, a positioning plate 4 is fixedly installed on the outer surface of the box body 1, the control motor 2 is stably installed at the position inside the positioning plate 4, and a crushing roller 5 is installed at the output end of the control motor 2. There are two crushing rollers 5, which are respectively installed inside the box body 1, and the moving directions of the two crushing rollers 5 are opposite. For the convenience of stably installing the control motor 2, a positioning plate 4 is fixedly installed at the position at the rear side of the box body 1, and the control motor 2 is installed at the position inside the positioning plate 4 to position the control motor 2 and make it stably used. And by two control motors 2 respectively controlling the rotation of the two crushing rollers 5, the raw materials are crushed.
[0031] In a preferred embodiment, there are two round rollers 31, and the sliding plate 33 is arranged at a position slightly below between the two round rollers 31 for moving the raw materials. After the raw materials are crushed by this device, they will move to the grinding position. To avoid material jamming, a rotatable material lifting plate 311 is installed inside the box body 1. And to prevent the raw materials from falling between the two grinding wheels 10, a sliding plate 33 is installed inside the box body 1. The raw materials are blocked by the sliding plate 33 so that the raw materials fall onto the grinding wheels 10, thus avoiding falling out of the box body 1.
[0032] In a preferred embodiment, a driving wheel 6 is installed at the output end of the control motor 2, and an intermediate wheel 7 is rotatably installed on the outer surface of the box body 1. The driving wheel 6 is meshed with the intermediate wheel 7, the intermediate wheel 7 is meshed with the linkage wheel 321, and a transmission rod 8 is rotatably installed at the position of the bottom end outside the box body 1. A rotating wheel 9 is fixedly installed at one end of the transmission rod 8, and the rotating wheel 9 is meshed with the linkage wheel 321. The other end of the transmission rod 8 is fixedly installed with a grinding wheel 10 for grinding the raw materials. There are two grinding wheels 10, which are respectively arranged inside the box body 1. For the convenience of use, a driving wheel 6 is installed at the output end of the control motor 2. The driving wheel 6 rotates with the intermediate wheel 7, and then the intermediate wheel 7 drives the linkage wheel 321 to rotate, thereby controlling the rotation of the round roller 31. By the meshing connection between the linkage wheel 321 and the rotating wheel 9, the rotation of the grinding wheel 10 is controlled, which is convenient for grinding the crushed raw materials and improving the processing effect of the raw materials.
[0033] The raw material is ground by the grinding wheel 10 and is ground into powder. As the volume of the raw material continues to decrease during the grinding process, the raw material will fall directly from the grinding position. In order to separate the powder from the granular material, a screening mechanism 11 is installed at the bottom of the box 1. The screening mechanism 11 includes a screening plate 111 and a connecting rod 112. The connecting rod 112 is rotatably installed at the bottom of the box 1, and the screening plate 111 is rotatably installed at one end of the connecting rod 112. A screening disc 12 is fixedly installed inside the screening plate 111, a disc 13 is fixedly installed on the outer surface of the rotating wheel 9, and a hollow bin 14 is fixedly installed on the outer surface of the disc 13. A round rod is provided inside the hollow bin 14, and the outer end of the round rod is rotatably connected to the connecting rod 112, and one end of the connecting rod 112 is rotatably connected to the screening plate 111.
[0034] During actual use, the grinding wheel 10 grinds the raw material, and the ground powder will fall onto the screen plate 111. As the raw material becomes smaller, when the raw material is too small to be stuck, it will also fall onto the screen plate 111 and fall onto the screen disc 12. At the same time, some powder will also fall onto the screen disc 12. In order to make the powder on the screen disc 12 fall into the inside of the screen plate 111, the rotating wheel 9 will drive the connecting rod 112 to move up and down while rotating, thereby driving the screen plate 111 to rotate, and the powder that falls on the screen disc 12 falls into the inside of the screen plate 111, so that the powder and granular materials can be collected separately after processing to meet the needs of use.
[0035] Specifically, the working process or working principle of a mechanical crusher is as follows: the raw materials for preparing semiconductor materials include silicon, germanium, gallium nitride, etc. These raw materials need to be processed during processing. The current method of processing the raw materials is to place the raw materials into the inside of the crushing box and stir the raw materials through the crushing roller 5. Although there is a grinding device installed inside the crushing box, when the crushed block raw materials accumulate on the grinding equipment, it is easy for the grinding equipment to be stuck, resulting in the grinding equipment being unable to continue grinding the raw materials, affecting the processing effect. Therefore, this device is designed to solve this problem.
[0036] This device can tilt the raw material from the position on one side of the grinding wheel 10 to avoid the raw material from piling up there, thereby avoiding the grinding wheel 10 from getting stuck, ensuring the normal use of the equipment, and normal processing of the raw material. The specific operation is to connect the external power supply, add the raw material into the interior of the box 1 from the top, and turn on the control motor 2 at the same time. The crushing roller 5 is driven to rotate by the control motor 2, and the raw material is added to the position between the two crushing rollers 5, and one crushing roller 5 rotates clockwise and the other crushing roller 5 rotates counterclockwise, thereby crushing the raw material.
[0037] After being crushed by the crushing rollers 5, the raw materials will become small pieces and fall from the position between the crushing rollers 5. When the raw materials fall onto the grinding wheel 10, the grinding wheel 10 will drive the raw materials to move to a position close to the inner wall of the box 1. Through the continuous rotation of the grinding wheel 10, the raw materials can be ground into powder. As the block raw materials continue to fall, more raw materials will accumulate at the grinding position, which can easily cause the grinding wheel 10 to get stuck. Therefore, when the control motor 2 is working, it will drive the intermediate wheel 7 to rotate through the driving wheel 6. The intermediate wheel 7 will drive the linkage wheel 321 to rotate, so the round roller 31 will rotate normally and drive the lifting plate 311 to rotate.
[0038] The stacked raw materials are lifted by the lifting plate 311 to separate them. The rotation direction of the round roller 31 in this device is opposite to that of the grinding wheel 10. Under the lifting of the lifting plate 311, part of the raw materials will be lifted onto the sliding plate 33. The sliding plate 33 will randomly drop the originally scattered raw materials onto the two grinding wheels 10. Then, under the rotation of the grinding wheel 10, the raw materials will continue to be moved to the position of the inner wall of the box body 1, and then continue to be ground. In this way, the amount of raw materials accumulated at the grinding position is reduced, the situation of material jamming during discharge is avoided, and the use is satisfactory.
[0039] The raw material is ground by the grinding wheel 10, and the ground powder will fall onto the screen plate 111. As the raw material becomes smaller, when the raw material is too small to be stuck, it will also fall onto the screen plate 111 and fall onto the screen pan 12. At the same time, some powder will also fall onto the screen pan 12. In order to make the powder on the screen pan 12 fall into the inside of the screen plate 111, the rotating wheel 9 will drive the connecting rod 112 to move up and down while the rotating wheel 9 rotates, thereby driving the screen plate 111 to rotate, and the powder that falls on the screen pan 12 falls into the inside of the screen plate 111, so that the powder and granular materials can be collected separately after the processing is completed to meet the needs of use.
[0040] It should be noted that the control motor 2 is a device or equipment existing in the prior art, or a device or equipment that can be implemented in the prior art. Its power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
