Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of screening, in particular to an agricultural automatic screening and cleaning device. BACKGROUND

[0002] The process that broken material is divided into different particle levels through one or several layers of screen surface is called screening, and the screening machine is a vibrating screening mechanical equipment for screening sand, gravel and other materials according to particle size. The screening process of the screening machine is generally continuous. After the raw material is fed into the screening machine (referred to as a screen), the material smaller than the screen hole size passes through the screen hole, which is called undersize product. The material larger than the screen hole size is continuously discharged from the screen surface, which is called oversize product.

[0003] According to the search, the patent with the patent publication number CN108212789A discloses an agricultural grain cleaning and screening device. The invention agitates and overturns through the two sets of spiral propulsion devices. The grain is continuously stirred and turned, and the dust and waste shells are removed by the air provided by the fan. The two sets of spiral propulsion devices are cyclically agitated and turned to ensure that the material can continuously contact the air, thereby improving the cleaning effect. The air flow containing dust and waste shells is filtered by the filter and falls into the isolation chamber for collection, thereby avoiding pollution of the working environment.

[0004] However, the above design still has some drawbacks. In the process of screening grain crops, due to the different qualities of grain crops, only one screening plate is used for screening, which results in a small amount of poor quality grain crops remaining after screening, thereby reducing the screening quality of grain crops. Therefore, we provide an agricultural automatic screening and cleaning device. UTILITY MODEL CONTENT
