However, when adding silicon particles, some larger silicon particles will be mixed with the newly added silicon particles. As the larger silicon particles continue to increase, they will hinder the smaller silicon particles from passing through the screen, thereby reducing the screening efficiency of the device.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4 A novel inoculant layered screening device comprises a body 1, a screening slot is provided on the body 1, support blocks 2 are symmetrically fixedly installed on the body 1, and a feed funnel 3 is fixedly installed between two support blocks 2;

[0023] Both sides of the body 1 are provided with strip holes connected to the screening slots, and moving blocks 4 are slidably installed in the two strip holes through elastic components, and an installation frame 5 is fixedly installed between the two moving blocks 4. A plurality of screens 6 are fixedly installed in the installation frame 5, and a transmission component for driving the moving block 4 to move is provided on the side of the body 1.

[0024] The multiple screens 6 are all in the shape of long strips. During screening, the silicon particles to be screened are put into the feed funnel 3, and then the silicon particles will pass through the feed funnel 3 and fall onto the screen 6. Through the cooperation of the transmission component and the elastic component, the moving block 4 can be driven to reciprocate in the strip hole. When the moving block 4 moves to the left end of the body 1, it will drive the installation frame 5 to move together, and through the multiple screens 6, it will drive the silicon particles on the screen 6 to move together. At the same time, screening is achieved in the process of movement, and the newly-input silicon particles are prevented from mixing with the screened silicon particles, thereby effectively improving the screening efficiency of the device.

[0025] The elastic component includes a slide rail 7 horizontally fixedly installed in the strip hole and a telescopic spring 8 sleeved on the slide rail 7. A slide hole is opened at one end of the moving block 4, and the moving block 4 is slidably sleeved on the slide rail 7. The two ends of the telescopic spring 8 are respectively fixedly connected to one end of the moving block 4 and the inner wall of the strip hole. The moving block 4 can move horizontally on the slide rail 7. When the moving block 4 moves toward the left end of the body 1, the telescopic spring 8 will be compressed.

[0026] The transmission assembly includes a rotating shaft 9 rotatably mounted on the side of the body 1, a turntable 10 fixedly sleeved on the rotating shaft 9, a shift block 11 fixedly mounted on the side of the turntable 10, a stopper 12 fixedly mounted on one of the moving blocks 4, and a driving motor 13 fixedly mounted on the side of the body 1 through a supporting frame, wherein the output shaft of the driving motor 13 is fixedly connected to the rotating shaft 9, and the stopper 12 is located on the rotation path of the shifter 11.

[0027] During screening, the driving motor 13 is started, and the rotating disk 10 is driven to rotate through the rotating shaft 9, and then the shifting block 11 is driven to rotate around the rotating shaft 9 through the rotating shaft 10. During the rotation process, the shifting block 11 will contact the stopper 12 fixedly installed on the moving block 4. Under the obstruction of the stopper 12, the moving block 4 will be driven to move in the strip hole, thereby driving the installation frame 5 and the multiple screens 6 to move toward the left end of the machine body 1, and the telescopic spring 8 is compressed;

[0028] While driving the moving block 4 to move, the shift block 11 will slide relative to the stop block 12 until the shift block 11 is separated from the stop block 12. At this time, under the action of the elastic force of the telescopic spring 8, the moving block 4 will drive the mounting frame 5 and the screen 6 to move rapidly toward the right end of the machine body 1, and the silicon particles will move on the screen 6 under the action of inertia. During the movement, the screen 6 will screen the silicon particles.

[0029] A rotating shaft 14 is rotatably mounted on one of the support blocks 2, a rotating roller 15 is fixedly sleeved on the rotating shaft 14, a plurality of rectangular grooves are provided on the surface of the rotating roller 15, the rotating roller 15 is rotatably arranged in the discharge port of the feed funnel 3, and a linkage assembly for driving the rotating shaft 14 to rotate is provided on the machine body 1, the linkage assembly includes two transmission wheels 16 and a belt 17 respectively fixedly sleeved on the rotating shaft 9 and the rotating shaft 14, and the belt 17 is sleeved on the two transmission wheels 16;

[0030] While the rotating shaft 9 is rotating, the transmission effect of the two transmission wheels 16 and the belt 17 will drive the rotating shaft 14 to rotate, thereby driving the rotating roller 15 to rotate in the discharge port of the feed funnel 3. When the rectangular groove on the rotating roller 15 rotates into the feed funnel 3, the silicon particles will enter the rectangular groove and rotate with the rotating roller 15. When the rectangular groove is rotated out of the feed funnel 3, the silicon particles in the rectangular groove will automatically fall onto the topmost screen 6, which can control the discharge speed of the feed funnel 3 to avoid the discharge of materials too quickly accumulating on the screen 6, so that the silicon particles can be spread flat on the screen 6, thereby further improving the screening efficiency of the device.

[0031] Guide blocks 18 are symmetrically fixedly installed in the feed funnel 3. The spacing between the two guide blocks 18 is greater than the width of the rectangular groove. The lower surfaces of the two guide blocks 18 are in sliding contact with the rotating roller 15. The guide blocks 18 can guide the silicon particles in the feed funnel 3, making it easier for the silicon particles to enter the rectangular groove.

[0032] In the utility model, during screening, the silicon granules to be screened are put into the feed funnel 3, and then the silicon granules pass through the feed funnel 3 and fall onto the screen 6. Through the cooperation of the transmission component and the elastic component, the moving block 4 can be driven to move back and forth in the bar hole. When the moving block 4 moves to the left end of the body 1, it will drive the installation frame 5 to move together, and through multiple screens 6, it will drive the silicon granules on the screen 6 to move together. At the same time, screening is achieved in the process of movement, and the newly-input silicon granules are prevented from mixing with the screened silicon granules, thereby effectively improving the screening efficiency of the device.

[0033] In general, in view of the technical problem that when silicon granules are added, some larger silicon granules will be mixed with the newly added silicon granules. As the larger silicon granules increase, the smaller silicon granules will be prevented from passing through the screen 6, which reduces the screening efficiency of the device. A technical solution is adopted: through the cooperation of the elastic component, the transmission component, the moving block 4 and the mounting frame 5, the silicon granules on the screen 6 can be driven to move continuously in one direction. Because the implementation process of the technical solution is: during screening, the silicon granules to be screened are put into the feed funnel 3. , and then the silicon granules will pass through the feed funnel 3 and fall onto the screen 6. Through the cooperation of the transmission component and the elastic component, the moving block 4 can be driven to reciprocate in the strip hole. When the moving block 4 moves to the left end of the body 1, it will drive the installation frame 5 to move together, and through multiple screens 6, it will drive the silicon granules on the screen 6 to move together, and screening will be achieved in the process of movement; therefore, the technical problem can be solved inevitably, and the technical effect achieved is: avoiding the mixing of the newly-input silicon granules with the screened silicon granules, and effectively improving the screening efficiency of the device.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
