[0030] Wherein, the left end of connecting shaft 19 is rotatably penetrated out of the outer surface of second protective box 6, the left side of second protective box 6 is fixedly installed with first protective box 5, and the inner wall of first protective box 5 is fixedly installed with servo motor 14.

[0031] Wherein, the output end of servo motor 14 and the outer wall of connecting shaft 19 are all fixedly sleeved with gear 13, and two gears 13 are meshed together.

[0032] Further, the outer wall of connecting shaft 19 is fixedly sleeved with adjusting plate 12, adjusting plate 12 is movably clamped on the inner wall of second protective box 6, the rear end of adjusting plate 12 extends out of the inner wall of rectangular groove 17, and the rear surface of second protective box 6 is fixedly connected with third protective box 7.

[0034] Further, the upper surface of two T-shaped sliding blocks 9 is fixedly connected with concave fixing plate 10, the upper surface of discharge pipe 4 is fixedly connected with fixed rod 11, the upper end of fixed rod 11 is slidably penetrated out of the upper surface of concave fixing plate 10, and the outer wall of fixed rod 11 is slidably sleeved with circular sleeve 15.

[0035] Further, the lower surface of circular sleeve 15 is fixedly connected with spring 16, spring 16 is movably sleeved on the outer surface of fixed rod 11, and the lower end of spring 16 is fixedly connected with discharge pipe 4.

[0036] Further, the outer surface of discharge pipe 4 is fixedly sleeved with circular baffle 3, the upper surface of second protective box 6 is opened with through hole 18 communicated with it, the number of discharge flow regulating component is three, and the structure of three discharge flow regulating components is completely same.

[0037] Furthermore, when installing the second protective box 6 as a whole, the staff first presses down the concave fixing plate 10. The concave fixing plate 10 drives the circular sleeve 15 to slide down through the inner wall of the fixing rod 11 and compress the spring 16.

[0038] Then another worker picked up the second protective box 6 as a whole and then slid the two T-shaped sliders 9 into the inner wall of the two T-shaped grooves 8. When the discharge pipe 4 moved to the position corresponding to the through hole 18 on the second protective box 6, the worker stopped pressing the concave fixing plate 10.

[0039] Under the action of spring 16, spring 16 drives concave fixing plate 10 to move downward through circular sleeve 15. Concave fixing plate 10 drives third protective box 7 to move upward through T-shaped slider 9 and rectangular plate 2, so that discharge pipe 4 enters the inner wall of through hole 18 and the lower surface of circular baffle 3 contacts the upper surface of second protective box 6, thus completing the overall installation of second protective box 6.

[0040] Furthermore, when adjusting the discharge flow rate of the vibrating screen, the vibrating screen is activated. Since the vibrating screen is existing technology, its operation requires no further explanation. The screened material falls through the discharge pipe 4 onto the upper surface of the regulating plate 12.

[0041] Then, the staff started the servo motor 14, which drove the gear 13 connected to it to rotate. The gear 13 drove the connecting shaft 19 to rotate through another gear 13. The connecting shaft 19 moved forward and drove the adjusting plate 12 to rotate, so that the front end of the adjusting plate 12 moved downward and the rear end of the adjusting plate 12 moved upward through the inner wall of the rectangular groove 17. Then, the material after screening fell through the inclined surface of the adjusting plate 12 and the opposite surface of the front end of the adjusting plate 12 and the inner wall of the second protective box 6.

[0042] Furthermore, by setting up a discharge flow rate adjustment component, the servo motor 14 is activated to adjust the relative distance between the adjustment plate 12 and the inner wall of the second protective box 6. This also increases the tilt angle of the adjustment plate 12, thereby increasing the discharge flow rate and discharge speed. By resetting the servo motor 14, the relative distance between the adjustment plate 12 and the inner wall of the second protective box 6 can be reduced. This also reduces the tilt angle of the adjustment plate 12, thereby reducing the discharge flow rate and discharge speed. This allows for flexible adjustment of the discharge flow rate of the vibrating screen, improving the practicality of the vibrating screen discharge flow rate adjustment device.

[0043] Working principle: When installing the second protective box 6 as a whole, the staff first presses down the concave fixing plate 10. The concave fixing plate 10 drives the circular sleeve 15 to slide down through the inner wall of the fixing rod 11 and compress the spring 16.

[0044] Then another worker picked up the second protective box 6 as a whole and then slid the two T-shaped sliders 9 into the inner wall of the two T-shaped grooves 8. When the discharge pipe 4 moved to the position corresponding to the through hole 18 on the second protective box 6, the worker stopped pressing the concave fixing plate 10.

[0045] Under the action of spring 16, spring 16 drives concave fixing plate 10 to move downward through circular sleeve 15. Concave fixing plate 10 drives third protective box 7 to move upward through T-shaped slider 9 and rectangular plate 2, so that discharge pipe 4 enters the inner wall of through hole 18 and the lower surface of circular baffle 3 contacts the upper surface of second protective box 6, thus completing the overall installation of second protective box 6. When it is necessary to disassemble second protective box 6, the operator only needs to press concave fixing plate 10 downward to make discharge pipe 4 disengage from the inner wall of through hole 18, and then the second protective box 6 can be disassembled as a whole. The whole disassembly process is simple and convenient, improving the convenience of overall installation and disassembly of second protective box 6.

[0046] Furthermore, when adjusting the discharge flow rate of the vibrating screen, the vibrating screen is activated. Since the vibrating screen is existing technology, its operation requires no further explanation. The screened material falls through the discharge pipe 4 onto the upper surface of the regulating plate 12.

[0047] Then, the staff started the servo motor 14, which drove the gear 13 connected to it to rotate. The gear 13 drove the connecting shaft 19 to rotate through another gear 13. The connecting shaft 19 moved forward and drove the adjusting plate 12 to rotate, so that the front end of the adjusting plate 12 moved downward and the rear end of the adjusting plate 12 moved upward through the inner wall of the rectangular groove 17. Then, the material after screening fell through the inclined surface of the adjusting plate 12 and the opposite surface of the front end of the adjusting plate 12 and the inner wall of the second protective box 6.

[0048] Furthermore, by setting up the discharge flow rate adjustment component, the servo motor 14 is activated to adjust the relative distance between the adjustment plate 12 and the inner wall of the second protective box 6. At the same time, the tilt angle of the adjustment plate 12 will increase, thereby increasing the discharge flow rate and discharge speed. By resetting the servo motor 14, the relative distance between the adjustment plate 12 and the inner wall of the second protective box 6 can be reduced. At the same time, the tilt angle of the adjustment plate 12 will decrease, thereby reducing the discharge flow rate and discharge speed, thus achieving flexible adjustment of the discharge flow rate of the vibrating screen.

[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
