Agricultural vibration screening device

An agricultural vibration screener comprises a hollow vibration screen body, a supporting frame and a vibration motor, the vibration screen body and the supporting frame are fixedly connected through arranged vibration springs, an arc-shaped feeding chamber is arranged at the head of the upwarp end of the vibration screen body, and a feeding opening is formed in the feeding chamber; by arranging the material stirring and hole cleaning device, when more particle impurities are attached to the surface of the filter screen, a sleeve plate can be driven by a rotating motor to swing in a reciprocating manner, and the sleeve plate drives a stirring plate to rotate, so that a brush is driven to rotate, and the brush cleans the filter screen; therefore, the influence of the particles on the vibration screening and filtering effect is avoided. 一种农业用振动筛选器，包括中空的振动筛本体、支撑架和振动电机，所述振动筛本体与支撑架之间通过设置的振动弹簧固接所述振动筛本体向上翘的一端头部设置有呈弧形的进料室，所述进料室开设有进料口，所述进料室中间位置水平设置有初级过滤筛网，本实用新型通过设置拌料清孔装置，当过滤网筛表面附有较多的颗粒杂质时，可以通过转动电机带动套板往复摆动，所述套板带动搅拌板转动，
