[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In the scheme of this application:

[0020] 1. The present application sets a second motor, a screw, blades, and a first spring. With the help of the drive of the second motor, the blades can be driven to rotate, and then a windshield is formed on both sides of the shell, so as to achieve the effect of concentrated discharge of dust generated by the crushing rod after the ore is crushed by the crushing rod, and it can also resist part of the crushed stone to try to avoid the crushed stone from flying out.

With the help of the third motor, the impeller composed of the cylinder and the rectangular plate can be driven to rotate in the storage frame, so as to form a large amount of water splashing upward, so as to achieve the effect of dust reduction for the discharged dust. When the position of the blade needs to be strengthened after the blade adjusts the distance between the crushing rods, the shape of the impeller composed of the original rectangular plate and the cylinder can be changed with the help of the rotation of the rectangular plate, and the position of the blade can be stabilized. That is, when crushing ore, the cooperation between the rectangular plate and the cylinder can achieve the effect of dust reduction, and after the blade adjusts the distance between the crushing rods, the cooperation between the rectangular plate and the cylinder can strengthen the stabilization effect of the blade.

[0022] 3.

That is, when the blade is crushing the ore, it plays a role in discharging dust. When not in use, the surface of the conveyor platform can be cleaned by changing the shape and position;

[0023] 4. By setting up the filter and the elliptical rod, with the help of the filter, some of the ores that have not been completely crushed can be blocked to facilitate secondary crushing. With the support of the elliptical rod, the angle of the filter can be adjusted, which makes it easier to collect the ore accumulated on the filter, making the collection more convenient and quick.

[0048] Embodiment 3

[0049] The production equipment for metallic silicon provided in the first or second embodiment is further optimized, specifically, as follows: Figure 1 and Figure 7 As shown, an auxiliary mechanism 4 is provided inside the shell 1, and the auxiliary mechanism 4 includes a filter screen 42, which is rotatably connected to the inside of the shell 1, and the middle position of the filter screen 42 is rotatably connected to the inside of the shell 1, and long holes 41 are opened on both sides of the shell 1, and connecting plates 43 are fixedly connected on both sides of the shell 1, and the surface of the connecting plate 43 is rotatably connected to a knob 44, and the arc surface of the knob 44 is fixedly connected to an elliptical rod 45, which is located below the filter screen 42, and the elliptical rod 45 plays a role of supporting the filter screen 42.

With the support of the elliptical rod 45, the angle of the filter 42 can be adjusted, thereby facilitating the collection of the ores accumulated on the filter 42, making the collection more convenient and quick.

[0051] Embodiment 4

[0052] The production equipment for metallic silicon provided in the first, second or third embodiment is further optimized, specifically, as follows: Figure 1 , Figure 2 and Figure 6 As shown, one end of the vertical rod 22 close to the fixed rod 21 is fixedly connected to the sliding rod 210, and one end of the sliding rod 210 away from the vertical rod 22 is slidably connected to the fixed rod 21. The arc surface of the sliding rod 210 is sleeved with a second spring 211, and the two ends of the second spring 211 are fixedly connected to the fixed rod 21 and the vertical rod 22 respectively;

The arc surface of the push rod 213 is fixedly connected to a pressure plate 214. The cross-sectional shape of the pressure plate 214 is an arc shape. The pressure plate 214 can just rest on the arc surface of the vertical rod 22 after rotation, so as to stabilize the vertical rod 22.

[0054] The blades 253 discharge dust when crushing ore, and can clean the surface of the conveyor platform 11 by changing their shape and position when not in use.

[0055] The use process of a production device for metallic silicon provided by the present invention is as follows:

[0056] Working principle: When the staff is crushing the silicon ore, the conveyor 11 transfers the selected silicon ore and drops it between the two crushing rods 13. Driven by the first motor 12, the two crushing rods 13 rotate in the direction of approaching each other to crush the silicon ore. Some of the ore that is not completely crushed will fall on the filter 42. At the same time, driven by the second motor 24, the wire wheel 251 drives the blades 253 to rotate, that is, a windshield is formed on both sides of the shell 1 to discharge the dust generated by the crushing. The blades 253 on both sides blow in the same direction, so that the dust is concentrated and discharged to one side. At the same time, driven by the third motor 34, the cylinder 35 drives the rectangular plate 37 to rotate in the storage frame 39, and the rectangular plate 37 will contact with the water in the storage frame 39, raising a large amount of water splashes upward, so as to better contact with the dust and achieve the effect of dust reduction.

[0057] When encountering larger individual silicon ores, in order to speed up the crushing effect, the blade 253 on one side of the first motor 12 can be stopped, and the distance between two adjacent blades 253 can be adjusted by driving the screw 252, so that the two blades 253 are moved closer to each other, and then the blades 253 are moved downward by sliding the slide plate 23. The blades 253 will squeeze the two first motors 12. Under the action of the first spring 28 and the sliding between the limit rod 27 and the vertical plate 26, the two first motors 12 will move away from each other. The first spring 28 is compressed, and the distance between the two crushing rods 13 will become larger. Under the action of the groove 254 on the blade 253, the blade 253 will be closely attached to the arc surface of the first motor 12, playing a stabilizing role. At this time, the blade 253 on the other side of the shell 1 can still discharge dust. If the stability between the blade 253 and the first motor 12 is to be strengthened, the cylinder 35 on the side of the first motor 12 can be stopped from rotating. With the help of the rotation between the rectangular plate 37 and the rectangular groove 36, the four rectangular plates 37 are rotated in the direction close to the shell 1, and finally a cross shape is formed. Then, with the help of the rotation and sliding between the long plate 33 and the round rod 32, the position of the cylinder 35 is adjusted, so that the rectangular plate 37 of the transformed shape is aligned with the slot 255 on the blade 253, so as to achieve the effect of stabilizing the position of the blade 253.

[0058] When it is not in use and the surface of the conveyor platform 11 needs to be cleaned, the vertical rod 22 is pulled upward, the slide rod 210 slides out of the fixed rod 21, and then the vertical rod 22 is pushed toward the middle, and the second spring 211 is deformed until the blade 253 is changed from a vertical state to a horizontal state and contacts the surface of the conveyor platform 11, and then the push rod 213 is pushed to make the pressure plate 214 rest on the arc surface of the vertical rod 22 to stabilize the elastic force of the second spring 211. At this time, the distance between the blades 253 can also be adjusted by screwing the screw rod 252 to increase the distance between the blades 253. The contact area between blade 253 and conveyor platform 11 will always be in contact with one end of blade 253 through the transmission of conveyor platform 11 to achieve a cleaning effect. When it is necessary to collect the silicon ore accumulated on the filter screen 42, the knob 44 is directly turned to drive the elliptical rod 45 to rotate. Due to the special shape of the elliptical rod 45, the higher end will be separated from the filter screen 42 and become in contact with the lower side of the filter screen 42. Then the filter screen 42 will rotate to this side and become inclined. The silicon ore on the filter screen 42 will slide down, and the staff can place the container in advance for collection.
