Abstract

The invention discloses a vibration type grain winnowing device, and relates to the technical field of agricultural machinery. The vibration type grain winnowing device comprises a box body; one sidewall of the box body is fixedly provided with a first protective shell in a buckling mode; one inside surface of the first protective shell is fixedly provided with an air blower; the opposite side walls of the box body are each provided with a mounting port; each mounting port is internally provided with an elastic plate; the box body is provided with a winnowing barrel transversely; one end of the winnowing barrel penetrates through one side wall of the box body, and extends into the first protective shell; one end face of the winnowing barrel is provided with air inlets uniformly; the circumferential side face of the lower part of the winnowing barrel is provided with discharging holes side by side; the circumferential side of the winnowing barrel is symmetrically provided with a pair of conveying channels in the length direction; and the circumferential side of the winnowing barrel is symmetrically connected with a pair of screening plates fixedly. According to the vibration type grain winnowing device, through arrangement the screening plate on the winnowing barrel, double screening of grains is achieved, and the screening efficiency is improved effectively; and the vibrationtype grain winnowing device has higher marketing value.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a vibrating grain winnowing device. Background technique [0002] Grain winnowing machine is a device used to separate lighter impurities in grains from grains. Its principle is that according to the principle of aerodynamics, according to the difference in density of light and heavy materials, the lighter impurities are blown out from the impurity outlet by the fan, while the lighter impurities are blown out from the impurity outlet by the fan. The heavy finished grain falls under gravity, separating the grain from impurities. When the grain winnowing machine in the prior art is winnowing the grain, due to the different quality and volume of the impurities mixed in the grain, it is difficult to control the blowing force of the fan. If the wind is blown away together, a large amount of impurities will remain in the grain after winnowing, and the winnow...
