Description

Vibrating cereal wind selector
Technical Field
The invention belongs to the technical field of agricultural machinery, and particularly relates to a vibrating grain winnowing device.
Background
The grain winnowing machine is used for separating lighter impurities from grains in grains, and the principle is that according to the aerodynamic principle, the lighter impurities are blown out from an impurity outlet by a fan according to the difference of the density of light and heavy materials, and heavier finished grains fall under the action of gravity, so that the separation of the grains and the impurities is realized. Cereal air separator among the prior art is when the cereal selection by winnowing, because thoughtlessly there are impurity quality and volume in the cereal differ, lead to the blowing dynamics of fan difficult to the accuse, wind-force can also blow away the corn together when great, wind-force can lead to still remaining a large amount of impurity in the cereal after the selection by winnowing finishes when less, and the selection by winnowing effect is relatively poor, if the repetition carries out the selection by winnowing to same cereal, leads to use cost to multiply again to operating personnel's intensity of labour has been increased. Therefore, a vibrating grain winnowing device needs to be developed to solve the above problems.
