[0034] The design of the stirring mechanism can make the materials more evenly distributed on the vibrating screen 17. The combination of the first fixing plate 13 and the vibrating screen 17 can cause a stronger relative movement between the soybeans and the soybean hulls. The soybeans can pass through the screen faster, thus improving the screening efficiency and shortening the time required for screening.

[0035] Embodiment 2

[0036] Referring to Figure 1 、 Figure 5 and Figure 6 A new type of screening machine, the screening mechanism includes a second fixing plate 15, a connecting spring 16, a vibrating screen 17, a contact plate 18, a vibrating motor 19 and a blowing fan 20. At the bottom end inside the lower housing 1, a plurality of second fixing plates 15 are evenly fixed. At the top of the second fixing plate 15, the connecting spring 16 is fixed. At the top of a plurality of connecting springs 16, a vibrating screen 17 is fixed. The vibrating screen 17 is slidably connected to the lower housing 1. At the inner sides of both ends at the bottom of the vibrating screen 17, the contact plates 18 are fixed. At both ends outside the lower housing 1, the vibrating motors 19 are fixed. The output ends of the vibrating motors 19 are in contact with the bottoms of the contact plates 18. At the inner side of one side at the top of the lower housing 1, a plurality of blowing fans 20 are evenly fixed;

[0037] Through the cooperation of the vibrating screen 17 and the blowing fan 20, the soybean hulls and the soybeans can be better separated. Through the design of the brush 14, the plug holes of the vibrating screen 17 can be better cleaned to improve the screening efficiency of the vibrating screen 17.

[0038] The clamping mechanism includes a third fixing plate 21, a sliding plate 22, a threaded rod 23, a rotary knob 24, a connecting frame 25 and a clamping plate 26. Two third fixing plates 21 are fixed to the bottom end of the outer side of the upper housing 3. The inner side of the third fixing plate 21 is slidably connected with a sliding plate 22. The inner side of the sliding plate 22 is threadedly connected with a threaded rod 23. The threaded rod 23 is rotatably connected with the third fixing plate 21. The top of the threaded rod 23 is fixed with a rotary knob 24. The inner sides of both sides of the rotary knob 24 are rotatably connected with a connecting frame 25. The inner side of one side of the connecting frame 25 is rotatably connected with a clamping plate 26. The clamping plate 26 is slidably connected with the third fixing plate 21. The clamping plate 26 is clamped with the lower housing 1;

[0039] Through the design of the clamping mechanism, when the equipment is maintained, repaired or the vibrating screen 17 is cleaned, the upper housing 3 can be quickly disassembled, which is convenient for checking and repairing the internal vibrating screen 17 and the parts that may malfunction, reducing the equipment downtime and improving the availability of the equipment.

[0040] A controller 27 is arranged on the outer side of the lower housing 1. The controller 27 is electrically connected with the rotating motor 7, the vibrating motor 19 and the blowing fan 20. Through the design of the controller 27, the operation of the rotating motor 7, the vibrating motor 19 and the blowing fan 20 can be better controlled;

[0041] A plurality of ventilation holes 28 are uniformly arranged on the inner side of the first fixing plate 13. The arrangement of the ventilation holes 28 is beneficial for the blowing fan 20 to better blow the soybean hulls out of the second discharge port 6, so as to separate the soybeans from the soybean hulls.

[0042] The use process of a new type of screening machine provided by the present utility model is as follows: The unshelled soybeans are put into the inner side of the upper housing 3 through the feeding port 4. The vibrating motor 19 is controlled to start through the controller 27. The output end of the vibrating motor 19 drives the contact plate 18 to vibrate, so that the vibrating screen 17 fixedly connected with the contact plate 18 vibrates. The vibration separates the soybeans from the bean hulls. At this time, the blowing fan 20 is started through the controller 27. The blowing fan 20 blows the lighter bean hulls, and the bean hulls are discharged through the second discharge port 6, thus completing the separation of the bean hulls and the soybeans;

[0043] At this time, the rotating motor 7 is controlled to start through the controller 27. The output end of the rotating motor 7 drives the first transmission rod 9 to rotate. Since the first transmission rod 9 is fixed to the first bevel gear 10, the rotation of the first transmission rod 9 drives the first bevel gear 10 to rotate, so that the second bevel gear 11 meshed with the first bevel gear 10 also rotates. Since the second bevel gear 11 is fixedly connected with the second transmission rod 12, the rotation of the second bevel gear 11 drives the second transmission rod 12 to rotate, so that the first fixing plate 13 fixedly connected with the second transmission rod 12 also rotates;

[0044] The design of the stirring mechanism can increase the movement intensity of the material, making the material more evenly distributed on the sieve mesh. The combination of the first fixing plate 13 and the vibrating sieve mesh 17 can generate a stronger relative movement between the soybeans and the soybean hulls, enabling the soybeans to pass through the sieve more quickly, thereby improving the screening efficiency and shortening the time required for screening.

[0045] When it is necessary to separate the lower housing 1 and the upper housing 3 to inspect and repair the internal mechanism, turn the knob 24. Since the knob 24 is fixedly connected to the threaded rod 23, the rotation of the knob 24 drives the threaded rod 23 to rotate, causing the sliding plate 22 threadedly connected to the threaded rod 23 to move accordingly. Also, since the sliding plate 22 is rotatably connected to the connecting frame 25, the movement of the sliding plate 22 drives the connecting frame 25 to move, causing the clamping plate 26 rotatably connected to the connecting frame 25 to move as well. After moving, the clamping plate 26 is no longer clamped to the lower housing 1.

[0046] Through the design of the clamping mechanism, when maintaining, overhauling or cleaning the vibrating sieve mesh 17 of the equipment, the upper housing 3 can be quickly disassembled, facilitating the inspection and repair of the internal vibrating sieve mesh 17 and the parts that may malfunction, reducing the equipment downtime and improving the usability of the equipment.
