[0029] The working principle of the mildew screening device for vegetable seeds in the utility model is as follows:

[0030] When the vegetable seed mildew screening device is used, batches of seeds are sent to the flexible vibration screening plate, and then the flexible vibration screening plate is started for screening. The flexible vibration screening plate can perform flexible vibration on the seeds, so that the seeds have the action of moving and turning over. After the seeds undergo a series of movements through the flexible vibration screening plate, the operator selects the mildewed seeds in the seeds, and after the mildewed seeds are selected, they are moved to the working range of the impurity recovery device, and the mildewed seeds are recovered by the recovery air duct. After the seed screening work is completed, the blocking plate is pushed open by the push cylinder, and the flexible vibration screening plate discharges the seeds from the placing plate through vibration, and the seeds fall into the guide hopper through the discharging plate, and the qualified seeds are recovered into the storage bag by the guide hopper. While the seed mildew screening efficiency is improved by the flexible vibration screening plate, the damage to the seeds during the screening work can also be reduced, and the impurities and dust attached to the outer surface of the seeds can be shaken off, thereby further improving the seed screening effect.

[0031] When the protection frame needs to be installed, align the notch below the protection frame with the notch of the fixed frame, and then install the protection frame on top of the fixed frame. The fixing work is completed by the fixing bolts on the outside of the protection frame. At this time, the fixed frame has a larger activity space and can perform vibration work of different intensities for seeds of different specifications and achieve different vibration effects. The fixed frame effectively prevents seeds from flying out of the working range of the flexible vibration screening plate.
