The bottom of both the first screen box 10 and the first screen box 9 is fixedly connected to a first winding box 11. The bottom of the second screen box 10 and the first screen box 9, and located on one side of the first winding box 11, is fixedly connected to a second winding box 27. The first winding box 11 is rotatably connected to a first winding roller 12 through a bearing. The second winding box 27 is rotatably connected to a second winding roller 13 through a bearing. The outer side of the first winding roller 12 is wound with a screen mesh 14. The top of both the second screen box 10 and the first screen box 9 is provided with a working cavity 16. One end of the screen mesh 14 passes through the working cavity 16 and extends into the second winding box 27 and is connected to the outer side of the second winding roller 13. The bottom of both the first screen box 9 and the second screen box 10 is provided with a bottom groove 15.

[0024] A self-locking motor 17 is fixedly connected to one side of both the first winding box 11 and the second winding box 27. The output end of the self-locking motor 17 is fixedly connected to one end of the corresponding first winding roller 12 and second winding roller 13. The output end of the self-locking motor 17 drives the first winding roller 12 and the second winding roller 13 to rotate.

[0025] Storage chambers 28 are provided inside the second sieve box 10 and the first sieve box 9, located on both sides of the working chamber 16. Both sides of the screen 14 extend into the storage chamber 28. An electric telescopic rod 29 is fixedly connected to the top of the inner cavity of the storage chamber 28. A clamping plate 30 is fixedly connected to the telescopic end of the electric telescopic rod 29. The surface of the clamping plate 30 is in contact with the surface of the screen 14. The clamping plate 30 is moved by the telescopic end of the electric telescopic rod 29 to clamp and limit the two ends of the screen 14.

[0026] Two first conveyor rollers 7 are rotatably connected inside both the conveyor platform 19 and the first drive block 4. The two first conveyor rollers 7 are connected to each other by a conveyor belt 5. A first motor 6 is fixedly connected to one side of both the conveyor platform 19 and the first drive block 4. The output end of each first motor 6 is fixedly connected to one end of a corresponding first conveyor roller 7. The output end of the first motor 6 drives one first conveyor roller 7 to drive the other first conveyor roller 7 to rotate through the conveyor belt 5. The graded agricultural products are transported through the conveyor belt 5.

[0027] One end of the first screening box 9 is fixedly connected to the discharge plate 20. The bottom of the base plate 3 and inside the slide rail 2 are both fixedly connected to sliders, and the sliders are all slidably connected to the inside of the slide rail 2, so that the sliders at the bottom of the base plate 3 slide inside the slide rail 2.

[0028] Example 2

[0029] Please see Figure 1 This utility model provides a technical solution: A second motor 21 is fixedly connected to the top of the fixed plate 1 and behind the slide rail 2. A turntable 22 is fixedly connected to the output end of the second motor 21. A pin 24 is fixedly connected to one side of the turntable 22. A guide rail 23 is slidably connected to the outside of the pin 24. A push column 25 is fixedly connected to one side of the guide rail 23. A positioning seat 26 is fixedly connected to the top of the fixed plate 1. One end of the push column 25 passes through the positioning seat 26 and is fixedly connected to one side of the first motor 6. The outside of the push column 25 is slidably connected to the inside of the positioning seat 26. The turntable 22 is driven to run by the second motor 21, thereby vibrating the screening mechanism.

[0030] The electrical structures of the second motor 21 and the first motor 6 are all existing products, powered by an external power supply. Different models can be selected according to the adaptability of the usage environment, and all are connected to a controller.

[0031] In summary, when using this agricultural product grading and screening machine, soybeans and other agricultural products are poured into the second screening box 10. At this time, the output end of the second motor 21 drives the turntable 22 to rotate, so that the turntable 22 drives the guide rail 23 to move back and forth through the pin shaft 24. The guide rail 23 drives the push column 25 and the first motor 6 to drive the base plate 3 to slide on the slide rail 2, so that the second screening box 10 and the first screening box 9 vibrate. Agricultural products that meet the size of the screen mesh 14 fall into the surface of the conveyor belt 5 inside the conveyor table 19. Agricultural products that do not meet the requirements fall into the first screening box 9 through the discharge pipe 18. Agricultural products that meet the size requirements are screened by the screen mesh 14 inside the first screening box 9 and fall into the surface of the conveyor belt 5 inside the first drive block 4. Agricultural products that do not meet the requirements fall into the collection container in front of the discharge plate 20 at the top of the fixed plate 1 through the discharge plate 20.

[0032] The first motor 6 drives a first conveyor roller 7 to rotate through its output end, which in turn drives another first conveyor roller 7 to rotate through the conveyor belt 5. This causes the conveyor belt 5 to move the agricultural products and drop them into the collection containers located on both sides of the base plate 3 at the top of the fixed plate 1.

[0033] If the size of the screen holes needs to be adjusted, the extension end of the electric telescopic rod 29 drives the clamping plate 30 to move upward, releasing the limit on the screen 14. Then, the output ends of the two self-locking motors 17 drive the first winding roller 12 and the second winding roller 13 to rotate, so that the screen 14 outside the first winding roller 12 is released, and the screen 14 is wound up by the second winding roller 13, so that the screen hole group to be used is moved to the working position for screening. After the position of the screen 14 is adjusted, the extension end of the electric telescopic rod 29 pushes the clamping plate 30 downward, so that the clamping plate 30 clamps and limits the two ends of the screen 14.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
