[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A vibrating screen for screening raw materials for baijiu (Chinese liquor): It includes a vibrating screen box 1, with an inlet 11 and an outlet 12 fixedly connected to its surface. A base plate 13 is provided at the bottom of the vibrating screen box 1. A telescopic damper 14 is fixedly connected to the surface of the base plate 13, and a return spring 15 is fixedly connected to the surface of the telescopic damper 14. The top of the return spring 15 is fixedly connected to the bottom of the vibrating screen box 1, and the telescopic end of the telescopic damper 14 is fixedly connected to the bottom of the vibrating screen box 1. A vibrating motor 16 is fixedly connected to the surface of the base plate 13, and the output end of the vibrating motor 16 is located at the bottom of the vibrating screen box 1. The vibrating motor 16 is the power source for the vibration system, driving the vibrating screen box 1 to vibrate periodically. The telescopic damper 14 controls the amplitude and frequency of the vibration system, absorbs energy during vibration, and reduces resonance and overshoot. The return spring 15 restores the vibrating screen box 1 to its initial position at the end of the vibration cycle. The vibration is achieved through the telescopic damper 14, the return spring 15, and the vibrating motor 16. The coordination between 6 achieves stable vibration of the vibrating screen box 1. A lifting mechanism is provided on the surface of the vibrating screen box 1. The lifting mechanism includes a first servo motor 2, which is fixedly connected to the surface of the vibrating screen box 1. A bidirectional lead screw 21 is fixedly connected to the output shaft of the first servo motor 2. A square nut 22 is threadedly connected to the surface of the bidirectional lead screw 21. A first adjusting rod 23 is rotatably connected to the surface of the square nut 22. A movable rod 25 is slidably connected to the surface of the vibrating screen box 1. A lifting plate 24 is fixedly connected to the top of the movable rod 25. A screen 26 is fixedly connected to the bottom of the movable rod 25. The end of the first adjusting rod 23 away from the square nut 22 is rotatably connected to the lower surface of the lifting plate 24. This lifting mechanism can change the horizontal height of the screen 26 inside the vibrating screen box 1. When facing large particles or high-hardness raw materials, the horizontal height of the screen 26 is raised to receive the material. After receiving the material, the screen 26 is moved back to the original horizontal height for screening, ensuring that the raw material can be discharged from the discharge port 12.

[0024] Furthermore, an adjustment mechanism is provided at the bottom of the base plate 13. The adjustment mechanism includes a support plate 3, which is located at the bottom of the base plate 13. A support column 31 is fixedly connected to the surface of the support plate 3. The base plate 13 is rotatably connected to the top of the support column 31. A second servo motor 32 is fixedly connected to the surface of the support plate 3. An adjustment screw 33 is fixedly connected to the output shaft of the second servo motor 32. A moving rod 34 is threadedly connected to the surface of the adjustment screw 33. A second adjustment rod 35 is rotatably connected to the surface of the moving rod 34. The end of the second adjustment rod 35 away from the moving rod 34 is rotatably connected to the bottom of the base plate 13. The adjustment mechanism can adjust the tilt angle of the vibrating screen box 1 during use. Different materials have better flowability at different tilt angles. By adjusting the tilt angle of the vibrating screen box 1, the adaptability of the vibrating screen is improved.

[0025] Furthermore, four sets of movable rods 25 are provided. The movable rods 25 drive the lifting plate 24 and the screen 26 to slide synchronously on the vibrating screen box 1. The lifting plate 24 and the screen 26 are parallel to each other. The four sets of movable rods 25 ensure the stability of the movable rods 25 and the screen 26 during the lifting process. Two sets of screens 26 are provided inside the vibrating screen box 1. The two sets of screens 26 can screen the raw materials twice. The two sets of screens 26 are used in conjunction with the two sets of discharge ports 12. The edges of the screens 26 are provided with sealing strips to ensure the effectiveness of the screens 26.

[0026] Furthermore, the first servo motor 2 drives the bidirectional lead screw 21 to rotate via its output shaft. The bidirectional lead screw 21 drives the square nut 22 to slide on the top of the vibrating screen box 1 through rotation. There are two sets of square nuts 22, and the sliding directions of the two sets of square nuts 22 are opposite. After the first servo motor 2 drives the bidirectional lead screw 21 to rotate, it locks the angle of the bidirectional lead screw 21, thereby limiting the position of the square nut 22 on the vibrating screen box 1 and ensuring the stability of the position of the square nut 22 on the vibrating screen box 1.

[0027] Furthermore, during the sliding process, the square nut 22 drives one end of the first adjusting rod 23 to move. During the movement, the first adjusting rod 23 drives the lifting plate 24 to move horizontally at the top of the vibrating screen box 1 by rotation. After the lifting is completed, the lifting plate 24 is supported by the first adjusting rod 23. The lifting plate 24 drives the screen 26 to move up and down inside the vibrating screen box 1 through the movable rod 25, thereby changing the horizontal height of the screen 26.

[0028] Furthermore, the base plate 13 rotates on one side of the top of the vibrating screen box 1 via the support column 31. The base plate 13 drives the vibrating screen box 1 to rotate synchronously via the telescopic damper 14. The vibrating screen box 1 changes its tilt angle by rotating, thereby enabling the vibrating screen box 1 to cope with materials of different flowability.

[0029] Furthermore, the second servo motor 32 drives the adjusting screw 33 to rotate via the output shaft. After rotation, the adjusting screw 33 is also locked in position by the second servo motor 32. The adjusting screw 33 drives the moving rod 34 to slide on the surface of the support plate 3 via rotation. During the movement, the moving rod 34 drives the base plate 13 to rotate via the second adjusting rod 35. There are two sets of second adjusting rods 35. During the movement, the moving rod 34 drives the two sets of second adjusting rods 35 to rotate. During the rotation, the second adjusting rods 35 push the base plate 13 to rotate.

[0030] Working principle: When dealing with large particles or high-hardness raw materials, the output shaft of the first servo motor 2 drives the bidirectional lead screw 21 to rotate. The bidirectional lead screw 21 drives the square nut 22 to slide on the top of the vibrating screen box 1. During the sliding process, the square nut 22 drives one end of the first adjusting rod 23 to rotate. At this time, the first adjusting rod 23 drives the lifting plate 24 to rise through rotation. The lifting plate 24 drives the screen 26 to rise through the movable rod 25. By raising the height of the screen 26, the impact force of the raw material on the screen 26 is reduced, thereby avoiding damage to the screen 26 and extending its service life.

[0031] The output shaft of the second servo motor 32 drives the adjusting screw 33 to rotate. The adjusting screw 33 rotates and drives one end of the moving rod 34 to move. During the movement, the moving rod 34 rotates and drives the base plate 13 to rotate on the surface of the support column 31. The base plate 13 drives the return spring 15 to rotate through the telescopic damper 14, changing the tilt angle of the vibrating screen box 1. By adjusting the tilt angle of the vibrating screen box 1, the adaptability of the vibrating screen machine is improved.
