[0012] As a further description of the above technical solution:

[0013] The sieve box has a through groove on one side, and sliding grooves are provided on both sides of the inner wall of the sieve box. One side of the sliding groove extends to the side of the through groove, and a sliding strip is slidably connected in the sliding groove. The same collection box is connected between the two sliding strips.

[0014] As a further description of the above technical solution:

[0015] Both sides of the sieve plate are provided with bonding devices. The bonding device includes a movable groove, which is opened on one side of the sieve plate. A bonding plate is slidably connected in the movable groove. A plurality of fixed grooves are opened on one side of the bonding plate, and a fixed rod is slidably connected in the fixed groove.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 - Figure 5This utility model provides a technical solution: a crushing device for silicon powder production, including a sieve box 3, a crushing module 2 connected to the top of the sieve box 3, a feeding box 1 on the top of the crushing module 2, a screening device 8 installed inside the sieve box 3, the screening device 8 including a motor 812 and multiple first stroke grooves 810, first stroke blocks 809 slidably connected in the first stroke grooves 810, and the same sieve plate 801 connected between the multiple first stroke blocks 809, a hinge block 802 connected to the bottom of the sieve plate 801, a connecting plate 803 hinged to one side of the hinge block 802, a reciprocating screw 808 connected to the output shaft of the motor 812, a screw seat 811 threadedly connected to the outer wall of the reciprocating screw 808, a moving block 806 connected to the top of the screw seat 811, and a connecting groove 807 opened on the top of the moving block 806. The groove 810 is opened on one side of the inner wall of the sieve box 3, and the first stroke groove 810 is arc-shaped. The two sides of the sieve plate 801 connected to the first stroke block 809 are attached to and slidably connected to the inner wall of the sieve box 3. The motor 812 is fixedly installed on one side of the outer wall of the sieve box 3, and the output shaft of the motor 812 extends into the sieve box 3. The inner wall of the connecting groove 807 is slidably connected to the outer wall of the connecting plate 803. Limiting grooves 805 are opened on both sides of the inner wall of the connecting groove 807, and limiting blocks 804 are slidably connected in the limiting grooves 805. One side of the limiting block 804 is connected to one side of the connecting plate 803. A through groove 4 is opened on one side of the sieve box 3, and sliding grooves 5 are opened on both sides of the inner wall of the sieve box 3. One side of the sliding groove 5 extends to one side of the through groove 4, and a sliding strip 7 is slidably connected in the sliding groove 5. The same collection box 6 is connected between the two sliding strips 7.

[0029] In a specific implementation, a screening device 8 is provided, and the output shaft of a motor 812 drives a reciprocating lead screw 808 to move. The reciprocating lead screw 808 drives a lead screw seat 811 to move reciprocally, causing the lead screw seat 811 to drive a moving block 806 to move left and right. This causes the moving block 806 to drive a connecting plate 803 in a connecting groove 807 to move, which in turn causes the connecting plate 803 to drive a hinge block 802 to move. The hinge block 802 then drives the screen plate 801 to move left and right. By providing an arc-shaped first stroke groove 810, the screen plate 801 can move. The screen plate 801 can move up and down while moving left and right, thereby improving the screening effect and increasing the screening efficiency. The screen plate 801 shakes and screens the silicon powder material falling from the top, so that qualified material falls into the collection box 6 for use, thus avoiding the impact of insufficiently crushed silicon powder on subsequent use. By setting a limiting block 804 to slide in the limiting groove 805, the limiting block 804 has a limiting effect on the connecting plate 803, preventing the connecting plate 803 from sliding out of the connecting groove 807 and affecting the normal operation of the device.

[0030] Both sides of the sieve plate 801 are provided with bonding devices 9. The bonding device 9 includes a movable groove 901, which is opened on one side of the sieve plate 801. A bonding plate 902 is slidably connected in the movable groove 901. Multiple fixed grooves are opened on one side of the bonding plate 902, and a fixed rod 904 is slidably connected in the fixed groove. The other end of the fixed rod 904 is connected to one side of the inner wall of the movable groove 901. A spring 905 is sleeved on the outer wall of the fixed rod 904. The two ends of the spring 905 are respectively connected to one side of the bonding plate 902 and one side of the inner wall of the movable groove 901. One side of the bonding plate 902 is attached to and slidably connected to one side of the inner wall of the sieve box 3. One side of the bonding plate 902 is semi-circular. Both sides of the inner wall of the movable groove 901 are provided with second stroke grooves 903, and a second stroke block 906 is slidably connected in the second stroke groove 903. One side of the second stroke block 906 is connected to one side of the bonding plate 902.

[0031] In a specific implementation, by setting up the bonding device 9, when the sieve plate 801 moves left and right, the bonding plate 902 on one side of the sieve plate 801 moves inward by compression and squeezes the spring 905, causing it to generate a rebound force. The spring 905 is supported by the fixed rod 904 to prevent the spring 905 from bending during compression and affecting the rebound effect. However, the bonding plate 902 on the other side of the sieve plate 801 moves outward by the elastic force of the spring 905, so that one side of the bonding plates 902 on both sides of the sieve plate 801 is always tightly bonded to the inner wall of the sieve box 3, thereby preventing silicon powder from falling from the gaps on both sides and affecting the sieving effect of the sieve plate 801.

[0032] Working principle: During use, raw materials are poured into the feeding box 1 and crushed by the crushing module 2. The crushed materials fall onto the top of the screen plate 801. Then, the motor 812 drives the reciprocating screw 808 to rotate. The reciprocating screw 808 drives the moving block 806 to move through the screw seat 811. The moving block 806 drives the connecting plate 803 in the connecting groove 807 to move. The connecting plate 803 drives the hinge block 802 to move. The hinge block 802 drives the screen plate 801 to move, causing the screen plate 801 to shake the raw materials on top. This allows for the screening of any lumps in the raw material that are not fully broken, preventing them from mixing with silicon powder and affecting subsequent use. When the screen plate 801 moves left and right, it presses one side of the bonding plate 902, causing the bonding plate 902 to move inward within the movable groove 901. Meanwhile, the other side of the bonding plate 902 moves outward due to the elasticity of the spring 905. This ensures that one side of the bonding plates 902 on both sides is always in contact with the inner wall of the screening box 3, preventing gaps between the two sides of the screen plate 801 and the inner wall of the screening box 3 from affecting the screening effect of the screen plate 801.
