[0028] Please refer to Figures 1-6 As shown, a technical solution provided by the present utility model:

[0029] A screening device for corn seeds, comprising a screening box 1 and a vibrator 2, characterized in that:

[0030] The screening box 1, inside which a sieve plate 3 is movably arranged, a waste chute 4 is movably arranged at the bottom of the sieve plate 3, an observation window 5 is opened on one side of the screening box 1, and a funnel 6 is fixedly arranged on the other side of the screening box 1;

[0031] The vibrator 2, on the top of which a workbench 7 is fixedly arranged, a limiting plate 8 is fixedly arranged at one end of the workbench 7, an extrusion plate 9 is movably arranged at the other end of the workbench 7, a shock-absorbing spring 10 is fixedly arranged at the bottom of the workbench 7, and a bottom plate 11 is fixedly arranged at the bottom of the spring.

[0032] In this embodiment, preferably, an embedding plate 12 is fixedly arranged at one end of the sieve plate 3, a tail plate 13 is fixedly arranged at the other end of the sieve plate 3, and a sieve mesh 14 is fixedly arranged inside the sieve plate 3.

[0033] Through the above solution, qualified seeds flow through the sieve mesh 14 towards the tail plate 13, and then towards the funnel 6 for collection. Unqualified seeds fall into the waste chute 4 through the leakage holes of the sieve mesh 14, realizing the screening of seeds.

[0034] In this embodiment, preferably, an embedding groove 15 is fixedly arranged at one end of the funnel 6, a collection groove 16 is fixedly arranged at one end of the embedding groove 15, fixing plates 17 are fixedly arranged at both ends of the collection groove 16, and a seed outlet pipe 18 is fixedly arranged at one end of the collection groove 16.

[0035] Through the above solution, after the seeds enter the funnel 6, the collection groove 16 is used to make them uniformly flow towards the seed outlet pipe 18, which is beneficial to the collection of seeds and can improve work efficiency.

[0036] In this embodiment, preferably, a threaded rod 19 is movably arranged inside the pressing plate 9, a fixed handle 20 is fixedly arranged at one end of the threaded rod 19, and an anti-slip pad 21 is fixedly arranged on one side of the pressing plate 9.

[0037] Through the above solution, by rotating the threaded rod 19 to drive the pressing plate 9, it is beneficial to fix the screening box 1 by the pressure of the cooperation between the pressing plate 9 and the limiting plate 8. At the same time, in order to avoid damage caused by friction or extrusion on the surfaces of the pressing plate 9 and the screening box 1, anti-slip pads 21 are arranged inside both the pressing plate 9 and the limiting plate 8.

[0038] In this embodiment, preferably, a cover plate 22 is movably arranged on the top of the screening box 1, connecting shafts 23 are fixedly arranged on both sides of the cover, rollers 24 are fixedly arranged at one end of the connecting shafts 23, and a groove handle 25 is opened on the upper surface of the cover plate 22.

[0039] Through the above solution, to prevent foreign objects accidentally falling from the outside from damaging the equipment when the device stops working, the rotating shafts and rollers 24 on both sides of the cover plate 22 cooperate with the chute inside the screening box 1, enabling the seeds to be poured into the box to the maximum extent.

[0040] In this embodiment, preferably, a pulling plate 26 is fixedly arranged at one end of the waste chute 4, and a handle 27 is fixedly arranged on one side of the pulling plate 26.

[0041] Through the above solution, when it is seen through the observation window 5 that the waste chute 4 is full, the waste chute 4 needs to be pulled out in time to pour out the internal waste and continue working. The handle 27 facilitates the handling of the waste chute 4, and the pulling plate 26 plays a limiting role.

[0042] In this embodiment, preferably, a controller 28 is fixedly arranged on the outer side of the top of the vibrator 2.

[0043] Through the above solution, the vibration frequency can be adjusted by the controller 28 to make the vibration reach a suitable working state, which is beneficial to improving work efficiency.

[0044] In this embodiment, preferably, limit posts 29 are fixedly arranged at both ends inside the shock-absorbing spring 10.

[0045] Through the above solution, the shock-absorbing spring 10 is prevented from shifting, so that the vibrator 2 is in a stable state during operation.

[0046] When the corn seed screening device of this embodiment is in use, the screening box 1 is placed on the top of the workbench 7. After fixing the screening box 1 firmly by rotating the fixing handle 20 and using the pressing plate 9 and the limiting plate 8, the tail of the cover plate 22 is lifted by using the groove handle 25 on the top of the cover plate 22. Then, by using the cooperation between the rollers 24 on both sides of the cover plate 22 and the internal chute of the screening box 1, the cover plate 22 is pushed to one side, so that the seeds can be poured into the box to the greatest extent. The fixing method is simple and the feeding is fast, which is beneficial to improving work efficiency. After the seeds enter the box, then the vibration frequency of the vibrator 2 is adjusted to a suitable frequency by using the controller 28, and the switch is started. While the vibrator 2 starts to work, it drives the screening box 1 to vibrate. After the screening box 1 starts to vibrate, the seeds inside use the inclined surface of the sieve mesh 14, and the qualified seeds move towards the embedding groove 15. During the moving process, the unqualified seeds fall into the waste chute 4 through the leakage holes of the sieve mesh 14, realizing the screening of the seeds.

[0047] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection required by the present invention is defined by the appended claims and their equivalents.
