[0002] Grain impurity cleaning refers to substances mixed in grains that are not the grains themselves or do not meet the edible or processing standards. Usually, impurities include sand, mud blocks, plant roots and dust, etc. Existing inside the grains will have an adverse impact on the quality, safety and processing efficiency of the grains.

[0003] According to the "vibrating cleaning sieve for grain impurities" with the Chinese patent publication number CN220941809U, it mainly describes that the flowing air in the main blowing pipe 1 drives the air flow in the extension pipe 2, thereby forming a vacuum adsorption principle. The fixed main board 3 and the fixed deputy board 4 are used to limit the rotation of the rotating rod 5, and the rotating rod 5 drives the vibration block 6 to rotate, thereby acting on the vibrating sieve 9, so that the vibrating sieve 9 slides up and down by gravity. The grains can be made to bounce up by vibration, and then the defective products, light impurities and dust in the grains can be adsorbed out by using the vacuum adsorption principle of objects to improve the cleaning efficiency of grain impurities. During this process, the heavier impurities in the grain impurities will move up and down with the grains, resulting in troublesome cleaning of the heavy-quality impurities.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following further describes the utility model with reference to the drawings.

[0018] Please refer to Figures 1-4A vibrating cleaning sieve for grain impurities shown in the figure includes a square cover 1 with openings at both ends. On one side of the opening of the square cover 1, a first support 2 is fixedly connected. A first motor is fixedly connected to the first support 2, and the output end of the first motor is fixedly connected to a first fan 3. The first motor drives the first fan 3 to rotate, which can draw air flow and direct it to the conveyor belt 5. A second motor is fixedly connected near the other opening of the square cover 1, and the output end of the second motor is fixedly connected to a roller 4. The second motor drives the roller 4 to rotate, thereby causing the conveyor belt 5 to rotate. The conveyor belt 5 is sleeved on the roller 4, and a first limiting roller 6 is in contact with the conveyor belt 5. Two first grooves 7 are opened at the bottom side of the first limiting roller 6 of the square cover 1. A limiting rod 8 is fixedly connected to the square cover 1 at the position of the first groove 7. A spring 9 is sleeved on the limiting rod 8, and both ends of the spring 9 are in contact with a slider 10. The electric push rod 13 drives the push plate 14 to strike the upper conveyor belt 5. At this time, the conveyor belt 5 and the grains on the conveyor belt 5 vibrate, and the light impurities will directly move out from the opening on the side of the square cover 1 close to the conveyor belt 5. The slider 10 is sleeved on the limiting rod 8, and a second limiting roller 11 is rotatably connected to the slider 10. The first limiting roller 6 and the second limiting roller 11 cooperate with the pressing roller 23 to limit the conveyor belt 5, which can maintain the stability of the rotation of the conveyor belt 5 and prevent the conveyor belt 5 from generating rotational deviation due to being struck. On both sides of the second limiting roller 11, there are support plates 12. An electric push rod 13 is fixedly connected to the upper end of the support plate 12, and the output end of the electric push rod 13 is fixedly connected to a push plate 14. A second groove is opened at one side of the bottom end of the square cover 1. A material distribution frame 15 is fixedly connected to the square cover 1 at the side of the second groove. A triangular column 17 is fixedly connected to the bottom side of the material distribution frame 15. An electric telescopic rod 18 is fixedly connected to the upper end of the triangular column 17, and the output end of the electric telescopic rod 18 is fixedly connected to an inclined plate 19. By driving the inclined plate 19 to move up and down through the electric telescopic rod 18, and promoting the grains falling on the inclined plate 19 to move up and down, the grains are dispersed, which is convenient for the second fan 22 to direct the grains. The grains fall from the highest point of the inclined plate 19, and the heavier impurities fall from the lowest point of the inclined plate 19. A third groove is opened on one side of the material distribution frame 15. A wind guiding frame 20 is fixedly connected to the square cover 1 at the side of the third groove. A second support 21 is fixedly connected in the wind guiding frame 20, and a second fan 22 is rotatably connected to the second support 21.

[0019] Among them, a pressing roller 23 is rotatably connected in the square cover 1 through a rotating shaft. The pressing roller 23 is in contact with the conveyor belt 5. The pressing roller 23 is close to the roller 4. There are eight pressing rollers 23. By setting the pressing roller 23, the conveyor belt 5 can be limited. Cooperating with the first limiting roller 6 and the second limiting roller 11, it can maintain the stable rotation of the conveyor belt 5 under the knocking of the electric push rod 13 and the push plate 14.

[0020] Among them, bevel angles are located on both sides of the baffle 25, and the bevel angles are in the same direction as the two rollers 4. The baffle 25 is fixedly connected inside the square cover 1, and the baffle 25 is located between the two first limiting rollers 6. By providing the baffle 25, it is possible to prevent grain impurities from falling into the conveyor belt 5.

[0021] Among them, the square cover 1 is fixedly connected to both ends of the protective plate 24, and the protective plate 24 is fixedly connected to the upper end of the baffle 25. By providing the protective plate 24, it can cooperate with the conveyor belt 5 to limit the grains.

[0022] Among them, guide plates 16 are fixedly connected to both sides inside the material distribution frame 15. The guide plates 16 are located at the bottom side of the square cover 1. By providing the two guide plates 16, it is possible to slow down the falling speed of the grains through the gaps of the guide plates 16, so as to separate the grains from the heavier materials.

[0023] Working principle: The grains are thrown onto the conveyor belt 5, and then the electric push rod 13 on the support plate 12 drives the push plate 14 to strike the upper side of the conveyor belt 5. At this time, part of the conveyor belt 5 is limited by the first limiting roller 6 and the second limiting roller 11. At the same time, a spring 9 is arranged between the second limiting rollers 11 to have a certain buffering effect. Thus, the conveyor belt 5 and the grains on the conveyor belt 5 can move stably towards the side of the second groove. Then the materials move to one side of the guide plate 16 and fall from the gaps of the guide plate 16. Some impurities can get stuck in the gaps of the guide plate 16 and fall. At this time, the second fan 22 rotates to blow the grains on the inclined plate 19, and through the thrust, the grains fall from one side of the highest point of the inclined plate 19. Then the heavier impurities can fall from the lowest point of the inclined plate 19, so as to achieve the effect of shunt and improve the processing efficiency of grain impurities.

[0024] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.

[0025] Other parts not detailed in the present invention belong to the prior art, so they will not be elaborated here.

[0026] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
