[0022] 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.
[0023] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a cleaning device for a corn harvester with good impurity removal effect, including a sieve frame 1. A motor 2 is fixedly connected inside the sieve frame 1. A roller 3 is fixedly installed at the output end of the motor 2. A belt 4 is installed on the outer wall of the roller 3. A rotating column 5 is installed inside the belt 4. The outer wall of the rotating column 5 is rotatably connected to the inside of the sieve frame 1. An eccentric wheel 6 is fixedly connected to the outer wall of the rotating column 5. A rotating shaft 7 is fixedly connected to the outer wall of the eccentric wheel 6. A rotating plate 8 is rotatably connected to the outer wall of the rotating shaft 7. A rotating shaft 9 is rotatably connected inside the rotating plate 8. A fixing block 10 is fixedly connected to the outer wall of the rotating shaft 9. A sieve plate 11 is fixedly connected to the outer wall of the fixing block 10. A limit component is provided inside the sieve frame 1.
[0024] Specifically, the sieve frame 1 serves to fix the motor 2. Starting the motor 2 drives the roller 3 to rotate, which in turn drives the belt 4 to move. The belt 4 drives the rotating column 5 to rotate, which in turn drives the eccentric wheel 6 to rotate. The eccentric wheel 6 drives the rotating shaft 7 to move, which in turn drives the rotating plate 8 to rotate. The rotating plate 8 rotates on the outer wall of the rotating shaft 9, which drives the fixed block 10 to reciprocate. The fixed block 10 drives the sieve plate 11 to reciprocate, thus achieving the effect of the first sieve of the corn.
[0025] Reference Figure 3 The limiting component includes a limiting post 12, the outer wall of the limiting post 12 is slidably connected to the inside of the sieve frame 1, and the outer wall of the limiting post 12 is fixedly connected to a second sieve plate 13, the upper surface of the second sieve plate 13 is fixedly connected to the lower surface of the first sieve plate 11.
[0026] Specifically, the limiting post 12 slides inside the sieve frame 1. The sieve frame 1 has a sliding groove inside that limits the limiting post 12. The limiting post 12 fixes the second sieve plate 13, and the second sieve plate 13 fixes the first sieve plate 11, thus achieving a double-layer sieve effect.
[0027] Reference Figure 4 The internal structure of the screening frame 1 is fixedly connected to a fixed plate 14. The internal structure of the fixed plate 14 is fixedly connected to a motor 15. The output end of the motor 15 is fixedly provided with a turntable 16. The outer wall of the turntable 16 is fixedly connected to a connecting shaft 17. The outer wall of the connecting shaft 17 is rotatably connected to a rotating plate 18. The internal structure of the rotating plate 18 is rotatably connected to a fixed shaft 19. The outer wall of the fixed shaft 19 is fixedly connected to a connecting block 20. The outer wall of the connecting block 20 is fixedly connected to a screen box 21. The outer wall of the screen box 21 is slidably connected to the internal structure of the screening frame 1.
[0028] Specifically, the sieve frame 1 fixes the fixed plate 14, which in turn fixes the motor 15. Starting the motor 15 drives the turntable 16 to rotate, which in turn drives the connecting shaft 17 to move. The connecting shaft 17 then drives the rotating plate 18 to rotate, which in turn drives the fixed shaft 19 to reciprocate. The fixed shaft 19 then drives the connecting block 20 to reciprocate, which in turn drives the sieve box 21 to reciprocate. The sieve frame 1 has a limiting groove inside to limit the movement of the sieve box 21, ensuring that the sieve box 21 slides stably.
[0029] Reference Figure 4 A blower 22 is fixedly connected to the outer wall of the sieve frame 1, and the blower 22 is located directly behind the sieve box 21.
[0030] Specifically, the sieve frame 1 serves to fix the blower 22, which is used to blow away the residual dust when sieving the corn, thus achieving an effective cleaning effect.
[0031] Reference Figure 1 The internal sliding connection of the screening frame 1 is a limiting strip 23, and the outer wall of the limiting strip 23 is fixedly connected to a receiving box 24.
[0032] Specifically, the inside of the sieve frame 1 is provided with a sliding groove to limit the limiting strip 23. By driving the limiting strip 23 to slide inside the sieve frame 1, the receiving box 24 can be driven out of the sieve frame 1 to achieve the effect of collecting and cleaning the corn.
[0033] Working principle: The corn to be cleaned is poured into the sieve plate 11. The motor 2 is started to drive the roller 3 to rotate. While the roller 3 is rotating, the belt 4 is driven to convey the corn, which in turn drives the rotating column 5 to rotate. The rotating column 5 drives the eccentric wheel 6 to rotate. While the eccentric wheel 6 is rotating, the rotating plate 8 rotates on the outer wall of the rotating shaft 7, which in turn drives the rotating plate 8 to rotate on the outer wall of the rotating shaft 9. At the same time, the fixed block 10 reciprocates, which in turn drives the sieve plate 11 to reciprocate and sieve the corn. After being sieved by the sieve plate 11, the corn is sieved again by the sieve plate 13. Meanwhile, the limiting column 12 slides back and forth inside the sieve frame 1, achieving a double-layer sieve effect, thus effectively cleaning the corn.
[0034] After the first sieving, the corn enters the sieve box 21 for a second sieving. By starting the motor 15, the turntable 16 can be rotated. As the turntable 16 rotates, the connecting shaft 17 can also be rotated, which in turn causes the rotating plate 18 to rotate on the outer wall of the connecting shaft 17. At the same time, the rotating plate 18 rotates on the outer wall of the fixed shaft 19, which in turn causes the connecting block 20 to reciprocate. Simultaneously, the sieve box 21 reciprocates inside the sieving frame 1. At the same time, by starting the blower 22, dust and impurities can be blown out of the device. The sieved corn enters the receiving box 24. By causing the receiving box 24 to slide out of the sieving frame 1, the corn can be collected. This device can not only effectively sieve the corn, but also further clean it.
[0035] 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.
