The objects of agricultural labor are living animals and plants, and the products obtained are the animals and plants themselves. In the process of agricultural planting, screening devices are needed to screen and process seeds.
[0003] For example, the Chinese patent number CN218872790U is a dust removal seed screening machine. During use, the utility model can not only perform multiple screenings on seeds but also remove dust from the seeds during the screening process. However, when the device is used for a long time, the seeds are easy to get stuck in the inside of the screen due to the small seed particles, which makes the inside of the screen easy to be blocked. The device is inconvenient to clean the seeds inside the screen, so the screen needs to be manually cleaned after use, which makes the use of this screening equipment inconvenient. Therefore, a seed screening device with dust removal function is proposed to solve the above-mentioned problems. Utility Model Content

[0011] Furthermore, the motor is connected to the inner rear wall of the screening box, and a thimble is fixedly installed on the outside of the cleaning roller.
[0012] Compared with the prior art, the utility model has the following advantages:
[0013] 1. The seed screening device with dust removal function can quickly screen seeds by setting a screening box. Materials enter the screening box through a conveyor. When multiple materials are screened, the exhaust duct is set, and the exhaust fan is started. Dust will enter the exhaust duct, be filtered by the activated carbon plate, and be discharged from the exhaust duct. By setting a screen body, three screen bodies with different apertures can be screened at the same time, which can achieve multiple screening with higher efficiency. By setting an anti-blocking mechanism, the various mechanisms of the anti-blocking mechanism cooperate with each other, so as to prevent the screen body from being blocked during screening, thereby improving work efficiency and saving manpower.
[0014] 2. The seed screening device with dust removal function fixes the limit spring by setting a limit cylinder, and the limit spring can buffer the connecting frame. When the vibration motor is started, the connecting frame will push the three screen bodies to shake synchronously, thereby accelerating the feeding of materials and avoiding mesh blockage. By setting an electric push rod, the controller drives the electric push rod to extend and retract to drive the cleaning brush to move left and right, so that the cleaning brush can clean the screen body. By setting a motor, when the controller drives the motor to start, it can drive the cleaning roller to rotate. At this time, the ejector on the cleaning roller can eject the blockage inside the screen body, thereby further achieving the anti-blockage effect. BRIEF DESCRIPTION OF THE DRAWINGS
