Specific implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment: Refer to Figures 1-4 A quartz sand particle screening device shown in the figure, including a screening box 1 and a feed hopper 2. A hose 6 is arranged inside the screening box 1, and the hose 6 is installed at the bottom of the feed hopper 2. A moving hole and a moving groove are respectively opened on the side and the inner wall of the side of the screening box 1. A sieve plate 7 is slidably installed on the moving hole and the moving groove together. A driving and fixing mechanism for moving the hose 6 and the sieve plate 7 is arranged on the screening box 1;

[0024] The driving and fixing mechanism includes an annular column 4 arranged inside the screening box 1. A limit ring 5 is installed at the bottom of the annular column 4. The hose 6 is rotatably sleeved on the limit ring 5. A fixing groove is opened on the side of the screening box 1. A telescopic rod 16 is installed on the inner wall of the side of the fixing groove. A moving block 17 is installed at the end of the telescopic rod 16. A driving unit for simultaneously rotating the annular column 4 and moving the moving block 17 is arranged on the screening box 1. A sliding hole is opened at the bottom of the moving block 17. A limit block 21 is slidably installed on the sliding hole. A limit groove is opened at the top of the sieve plate 7. A trapezoidal block is installed on the side of the sieve plate 7. An elastic moving unit adapted to the limit block 21 is arranged on the moving block 17.

[0025] With the above structure, during use, first pour quartz sand into the feed hopper 2, and then rotate the annular column 4 through the driving unit. The rotation of the annular column 4 will cause the limiting ring 5 to rotate, and the rotation of the limiting ring 5 will cause the other end of the hose 6 to move, thereby enabling the quartz sand to evenly fall on the sieve plate 7, thus avoiding the accumulation of quartz sand at one position and affecting the screening progress. At the same time, the driving unit will cause the moving block 17 to move. The movement of the moving block 17 will cause the limiting block 21 to move. The movement of the limiting block 21 will contact the trapezoidal block and avoid it. When the limiting block 21 corresponds to the limiting groove, the limiting block 21 will reset under the action of the elastic moving unit. The reset of the limiting block 21 will fix the sieve plate 7, thereby facilitating the quick fixation of the sieve plate 7. When replacement is needed, directly move the limiting block 21 upward through the elastic moving unit. The upward movement of the limiting block 21 will release the fixation of the sieve plate 7, thereby facilitating the replacement of the sieve plate 7, and thus facilitating the screening of quartz sand of different sizes.

[0026] As Figures 1-3 shown, the driving unit includes an annular cavity opened in the screening box 1. An annular tooth plate 3 is movably installed in the annular cavity. An annular hole is opened in the top inner wall of the screening box 1. The annular column 4 passes through the annular hole and is installed at the bottom of the annular tooth plate 3. An L-shaped fixing block is installed on the side of the screening box 1. A motor 8 is installed on the top of the L-shaped fixing block. Rotation holes are opened on the tops of the screening box 1 and the L-shaped fixing block respectively. A rotating rod 12 and a movable rod 9 are respectively rotatably installed in the two rotation holes. The top end of the movable rod 9 is installed on the output shaft of the motor 8. Transmission wheels 10 are sleeved on both the movable rod 9 and the rotating rod 12. A belt 11 is tensioned between the two transmission wheels 10. The bottom end of the rotating rod 12 extends into the annular cavity and is installed with a gear 13. The gear 13 meshes with the annular tooth plate 3. A circular plate 14 is installed at the bottom of the movable rod 9. An eccentric rod 15 is eccentrically installed at the bottom of the circular plate 14. A fixing rod 18 is installed on the top of the moving block 17. A connecting plate 19 is rotatably sleeved on both the eccentric rod 15 and the fixing rod 18. The advantage of such a setting is that through the setting of the annular tooth plate 3, the L-shaped fixing block, the motor 8, the movable rod 9, the transmission wheel 10, the belt 11, the rotating rod 12, the gear 13, the circular plate 14, the eccentric rod 15, the fixing rod 18 and the connecting plate 19, while the annular column 4 rotates, the moving block 17 moves, so as to shake the sieve plate 7 while evenly feeding.

[0027] Specifically, the output of the motor 8 causes the movable rod 9 to rotate. The rotation of the movable rod 9 causes the rotating rod 12 to rotate through the transmission wheel 10 and the belt 11. The rotation of the rotating rod 12 causes the gear 13 to rotate. The rotation of the gear 13 causes the annular toothed plate 3 to rotate. The rotation of the annular toothed plate 3 causes the annular column 4 to rotate. The rotation of the annular column 4 causes the limiting ring 5 to rotate. The rotation of the limiting ring 5 causes the other end of the hose 6 to move, thereby making the quartz sand evenly fall on the sieve plate 7, avoiding the accumulation of quartz sand at one position and affecting the screening progress. At the same time, the rotation of the movable rod 9 causes the circular plate 14 to rotate. The rotation of the circular plate 14 continuously causes the fixed rod 18 to move through the eccentric rod 15 and the connecting plate 19. The movement of the fixed rod 18 causes the moving block 17 to move. The movement of the moving block 17 causes the sieve plate 7 to move back and forth through the limiting block 21, thereby making the quartz sand move, so that the quartz sand is more likely to pass through the sieve holes of the sieve plate 7.

[0028] As Figure 4 shown, a soft pad is installed at the bottom of the limiting block 21. The advantage of this setting is that through the setting of the soft pad, a certain buffering effect is achieved, avoiding excessive vibration when the limiting block 21 resets.

[0029] As Figure 4 shown, the elastic moving unit includes a movable cavity opened on the moving block 17. Two sliding rods are installed on the opposite inner walls of the movable cavity. A slider 20 is slidably sleeved on the two sliding rods together. The limiting block 21 is installed at the bottom of the slider 20. A spring 22 is installed at the top of the slider 20. The other end of the spring 22 is installed on the top inner wall of the movable cavity. A pulling element for moving the slider 20 is provided on the moving block 17. The advantage of this setting is that through the setting of the sliding rods, the slider 20, the limiting block 21 and the spring 22, it is convenient to fix the sieve plate 7.

[0030] Specifically, when the sieve plate 7 is inserted into the moving hole, at this time, the motor 8 is used to move the moving block 17. The movement of the moving block 17 causes the limiting block 21 to move through the slider 20. When the limiting block 21 contacts the inclined surface of the trapezoidal block, the continuous movement of the moving block 17 causes the limiting block 21 to be squeezed and move upward. When the limiting block 21 corresponds to the position of the limiting groove, under the action of the spring 22, the limiting block 21 will enter the limiting groove, thereby fixing the sieve plate 7. At the same time, the further movement of the moving block 17 will cause the sieve plate 7 to move, so as to screen the quartz sand, which is convenient to use. When removing, first make the slider 20 move upward through the pulling unit. The upward movement of the slider 20 causes the limiting block 21 to move. The movement of the limiting block 21 releases the fixation of the sieve plate 7, thereby facilitating the replacement of the sieve plate 7, and thus facilitating the screening of quartz sand of different sizes.

[0031] As Figure 4As shown, the pulling element includes a movable plate 23 installed on the side of the slider 20. A through hole adapted to the movable plate 23 is provided on the side of the moving block 17. The advantage of this setting is that it facilitates the movement of the slider 20.

[0032] As Figure 4 shown, a rope sleeve 24 is installed on the side of the movable plate 23, and a sleeve rod 25 adapted to the rope sleeve 24 is installed on the side of the moving block 17. The advantage of this setting is that through the arrangement of the rope sleeve 24 and the sleeve rod 25, it is convenient to fix the slider 20 at a certain height, so that it is not necessary to continuously pull the movable plate 23.

[0033] As Figure 1 shown, four support columns are installed at the bottom of the screening box 1, and buffer pads are installed at the bottoms of the four support columns. The advantage of this setting is that through the arrangement of the support columns and the buffer pads, a certain buffering effect is achieved, reducing the impact caused by vibration.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
