[0013] Compared with the prior art, the utility model has the following beneficial effects: the vibrating wheat seed screening device not only improves the vibration screening effect, but also improves the material guiding capacity and separation capacity of the screening device;

[0014] (1) Wheat seeds are fed from the feed port, and then the wheat seeds are collected and screened by the screening basket. After the working motor is started, the eccentric disk is driven to rotate, and the eccentric disks are connected by a connecting shaft, and an eccentric rotation is formed between the connecting shaft and the eccentric disk. When the eccentric disk rotates eccentrically, different height surfaces contact the bottom position of the screening basket. At this time, after the reset spring forms elastic deformation, the adjustment column moves inside the movable groove and is guided by the guide assembly. Therefore, under the formation of the reset spring and the eccentric movement of the eccentric disk, the vibration of the screening basket is formed, thereby improving the overall vibration screening effect during the working process;

[0015] (2) The guide plate is connected and installed by using the mounting plate and the shaft rod. After the telescopic rod works, the angle of the guide plate can be changed. A guide groove is provided inside the top of the guide plate. The guide groove facilitates the guide work of the wheat seeds. At this time, after the wheat seeds are screened inside the screening basket, the two guide plates complete the guide work, and finally the filter screen guides the seeds to the inside of the separation box. Therefore, the overall guide capacity is better improved during the work process.

[0016] (3) By installing the oblique screening plate inside the separation box, when the wheat seeds reach the position of the oblique screening plate, secondary screening can be formed. At this time, the screening basket will screen the large material impurities, and the oblique screening plate will screen the small material impurities. The seeds are obliquely discharged above the oblique screening plate and finally discharged from the material outlet, while the small material impurities reach the bottom of the separation box and are treated by air supply after the blower is started. The impurities are finally discharged at the position of the impurity outlet, thereby improving the overall separation capacity during the working process. BRIEF DESCRIPTION OF THE DRAWINGS
