Description

Technical Field

[0001] The utility model belongs to the technical field of silicon material crushing, and particularly relates to a silicon material crushing device. Background Art

[0002] Silicon material is an important semiconductor material. The silicon used in the electronics industry should have high purity and excellent electrical and mechanical properties. Silicon material has a high use value. In the production process, the silicon material needs to be crushed to facilitate the subsequent processing and use of the silicon.

[0003] At present, when silicon materials are crushed, the crushed silicon materials will be stored in different sizes. At this time, they need to be screened and then the unqualified silicon materials need to be crushed again. However, the existing screening is to fix the screen in the crusher for screening after crushing. This method makes the screening method of the screen single and cannot achieve good working effect. In addition, the larger silicon materials on the screen are not easy to remove and are easy to be blocked, which leads to poor screening effect and affects production efficiency.

[0004] Therefore, we propose a silicon material crushing device to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned existing problems, one of the purposes of the utility model is to provide a silicon material crushing device, which can perform good screening of crushed silicon materials and can quickly take out the screened larger silicon materials for re-crushing, thereby solving the problems of poor screening effect and inconvenience in taking out unqualified silicon materials when screening the crushed silicon materials, and easy clogging of the screen, which affects the screening effect and production efficiency.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a silicon material crushing device, comprising: a crushing box, a feed port is arranged on the crushing box; a crushing wheel is arranged in the crushing box; a material storage box is arranged in the crushing box, and a screening mechanism is arranged in the crushing box, and the screening mechanism includes:

[0007] A chute is provided on the inner wall of the crushing box; a screen is slidably connected in the chute; a spring is arranged on the side wall of the screen; a motor is arranged on the side wall of the crushing box; a cam is arranged on the output shaft of the motor, and a cleaning mechanism is arranged in the crushing box.

[0008] In one of the technical solutions disclosed in the utility model, the wire clamping mechanism includes: the cleaning mechanism includes: a second slide groove, which is opened on the inner wall of the crushing machine box; a push plate, which is slidably connected in the second slide groove; a threaded rod, which is arranged in the second slide groove, and one end passes through the crushing machine box; the threaded rod and the push plate are threadedly connected; and a discharge port, which is opened on the side wall of the crushing machine box.

[0009] In one of the technical solutions disclosed in the utility model, a handle is provided on the material storage box.

[0010] In one of the technical solutions disclosed in the present utility model, a cover plate is provided on the discharge port.

[0011] In one of the technical solutions disclosed in the utility model, a placement platform is provided on the side wall of the crushing box.

[0012] In one of the technical solutions disclosed in the utility model, a handle is provided at one end of the threaded rod that passes through the crusher box.

[0013] In one of the technical solutions disclosed in the present utility model, the feed port is set at an oblique angle.

[0014] In one of the technical solutions disclosed in the present utility model, the threaded rod is rotatably connected to the second slide groove via a bearing.

[0015] From the above description, it can be seen that the beneficial effects of the utility model are:

[0016] 1. The rotation of the motor output shaft drives the cam to rotate, pushing the screen, so that the screen slides in the slide slot, and the elastic force of the spring pushes the screen downward in the slide slot. Combined with the characteristics of the cam and the action of the spring, the screen can be moved up and down, and then vibrate. In this way, the silicon material on the screen can be well screened and the screening effect can be improved.

[0017] 2. By rotating the threaded rod, the push plate is driven to slide in the second slide groove, and then the larger silicon blocks on the screen can be pushed out through the discharge port for re-crushing. In this way, the silicon blocks can be prevented from clogging the screen, resulting in the inability to screen, affecting the screening quality and production efficiency.

[0029] Silicon is the most abundant element semiconductor in the earth's crust. It has superior properties and relatively mature process technology. It has become the main raw material for solid-state electronic devices. In order to meet the needs of ultra-large-scale integrated circuits, high-integrity and high-uniformity silicon single crystal preparation technology is being developed. Therefore, the role and value of silicon materials are very large. During production, an important step is to crush the silicon blocks.

[0030] In the related art, the existing silicon material crushing device will cause the crushed silicon material to be uneven in size when crushing the silicon material, so it needs to be screened. However, the existing screening method is to install the screen on the crusher for screening. This screening method is single, and larger silicon blocks will cause the screen to be blocked, which will then affect the screening effect and quality, resulting in affecting production efficiency.

[0031] In order to solve the problems in the related art to a certain extent, the present application implements a silicon material crushing device. When in use, the silicon material is poured into the crushing box 110 from the feed port 120, and is crushed by the crushing wheel 130. The crushed silicon material falls on the screen 220, and the cam 250 is driven to rotate by the starting motor 240. Due to the characteristics of the cam 250, when the rotation occurs, the screen 220 can move in the slide 210, and the screen 220 passes through the spring 230 in the slide 210. The elastic force pushes the screen 220 downward, and combined with the rotation of the cam 250, the screen 220 can be vibrated up and down, and then the silicon blocks that fall into the screen 220 can be screened. When a large number of silicon blocks are piled up on the screen 220 and cannot be screened out, the push plate 320 is driven to slide in the second slide groove 310 by rotating the threaded rod 330, and the unqualified silicon blocks are pushed out from the discharge port 340 for re-crushing. In this way, the screening effect and quality can be improved, and the efficiency during production can be improved.

[0032] The following is combined with Figure 1-4 The embodiment of the present application provides a silicon material crushing device, including: a feed port 120 arranged on a crusher box 110; a crushing wheel 130 arranged in the crusher box 110; a material storage box 140 arranged in the crusher box 110, and a screening mechanism 200 is arranged in the crusher box 110, and the screening mechanism 200 includes: a chute 210 opened on the inner side wall of the crusher box 110; a screen 220 slidably connected in the chute 210; a spring 230 arranged on the side wall of the screen 220; a motor 240 arranged on the side wall of the crusher box 110; a cam 250 arranged on the output shaft of the motor 240, and a cleaning mechanism 300 is arranged in the crusher box 110.

[0036] When in use, the threaded rod 330 is rotated to drive the push plate 320 to slide in the second slide groove 310, so that the unqualified silicon blocks screened by the screen 220 can be pushed and cleaned, and pushed out from the discharge port 340 by the push plate 320 to be crushed again.
