[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a grain threshing machine, comprising a support plate 1, a motor 2 fixedly connected inside the support plate 1, a roller 3 fixedly mounted at the output end of the motor 2, the outer wall of the roller 3 rotatably connected to the inside of the support plate 1, a belt 4 mounted on the outer wall of the roller 3, a turntable 5 mounted on the inner wall of the belt 4, the outer wall of the turntable 5 rotatably connected to the inside of the support plate 1, a connecting shaft 6 fixedly connected to the outer wall of the turntable 5, a rotating plate 7 rotatably connected to the outer wall of the connecting shaft 6, a rotating shaft 8 fixedly connected inside the rotating plate 7, a fixed plate 9 rotatably connected to the outer wall of the rotating shaft 8, a fixed frame 10 fixedly connected to the outer wall of the fixed plate 9, a limiting component mounted on the outer wall of the fixed frame 10, the limiting component including a sliding column 11, the outer wall of the sliding column 11 fixedly connected to the outer wall of the fixed frame 10, the outer wall of the sliding column 11 slidably connected to the inside of a limiting frame 12, and the outer wall of the limiting frame 12 fixedly connected to the outer wall of the support plate 1.

[0026] Specifically, the support plate 1 fixes the motor 2. Starting the motor 2 drives the roller 3 to rotate, which in turn drives the belt 4 to rotate. The belt 4 then drives the turntable 5 to rotate, which in turn drives the connecting shaft 6 to rotate inside the rotating plate 7. Simultaneously, the rotation of the rotating plate 7 drives the rotating shaft 8 to rotate inside the fixed plate 9. The fixed plate 9 drives the fixed frame 10 to reciprocate, and the fixed frame 10 drives the sliding column 11 to slide inside the limiting frame 12. The limiting frame 12 serves as a limiting mechanism. The reciprocating motion of the fixed frame 10 achieves the effect of sieving grain residue, thus accelerating the sieving efficiency.

[0027] Reference Figure 4 and Figure 5 A filter frame 13 is slidably connected inside the fixed frame 10. A limit groove 24 is opened inside the filter frame 13. A locking post 14 is slidably connected inside the fixed frame 10. A sliding piece 15 is fixedly connected to the outer wall of the locking post 14. One end of a spring 16 is fixedly connected to the outer wall of the sliding piece 15. The other end of the spring 16 is fixedly connected inside the fixed frame 10.

[0028] Specifically, the filter frame 13, which slides inside the fixed frame 10, is used to sieve grain residue. The limiting groove 24 inside the filter frame 13 can be used to limit the clamping column 14 to prevent it from falling off during sieving. By pulling the clamping column 14, the sliding piece 15 is driven to slide inside the fixed frame 10. The sliding piece 15 drives the spring 16 to be compressed, and the spring 16 rebounds, achieving the effect of quickly disassembling the filter frame 13 so as to collect the grain residue after threshing.

[0029] Reference Figure 6 A threshing box 17 is fixedly connected to the upper surface of the support plate 1. A second motor 18 is fixedly connected to the outer wall of the threshing box 17. A first sprocket 19 is fixedly installed at the output end of the second motor 18. A chain 20 is installed on the outer wall of the first sprocket 19. A second sprocket 21 is installed on the inner wall of the chain 20. A threshing roller 25 is fixedly connected to the outer wall of the second sprocket 21. The outer wall of the threshing roller 25 is rotatably connected to the inside of the threshing box 17. A discharge port 22 is fixedly connected to the upper surface of the threshing box 17. A discharge port 23 is fixedly connected to the outer wall of the threshing box 17.

[0030] Specifically, the support plate 1 fixes the threshing box 17, and the threshing box 17 fixes the motor 18. The motor 18 drives the sprocket 19 to rotate, the sprocket 19 drives the chain 20 to rotate, the chain 20 drives the sprocket 21 to rotate, and the sprocket 21 drives the threshing roller 25 to rotate inside the threshing box 17. The threshing roller 25 is used to thresh the remaining grains.

[0031] Working principle: When the threshing mechanism is needed, the remaining grains to be threshed are first fed into the feed inlet 22. The motor 18 drives the sprocket 19 to rotate, which in turn drives the chain 20 to rotate. Simultaneously, the chain 20 rotates, driving the sprocket 21 to rotate, and the threshing roller 25 to rotate inside the threshing box 17, achieving the effect of threshing the remaining grains. The threshed grains fall into the filter frame 13 for sieving, while the waste is discharged through the discharge outlet 23. At this time, the motor 2 drives the roller 3 to rotate, which in turn drives the belt 4 to rotate. The belt 4 rotates the connecting shaft 6 inside the rotating plate 7, which in turn rotates the rotating plate 7. The rotating plate 7 then drives the rotating shaft 8 inside the fixed plate 9, which in turn... The fixed frame 10 reciprocates, and while the fixed frame 10 moves, it drives the sliding column 11 to slide back and forth inside the limiting frame 12, thereby achieving the effect of sieving the remaining grain after threshing. When it is necessary to remove the filter frame 13, the sliding plate 15 is slid inside the fixed frame 10 by pulling the locking column 14, which in turn drives the spring 16 to compress and simultaneously drives the locking column 14 to slide out of the limiting groove 24. At this time, the filter frame 13 can be quickly disassembled by pulling it out. By cleaning the filter frame 13 regularly, clogging of the filter frame 13 can be prevented, thus avoiding affecting the sieving. This device can not only achieve the effect of uniformly sieving the remaining grain, but also achieve the effect of disassembling the filter frame 13 to prevent clogging during sieving, thereby extending the service life of the device.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
