Agricultural swinging winnowing device

Abstract

The invention discloses an agricultural swinging winnowing device. The agricultural swinging winnowing device is characterized in that a bearing at the upper part of a worm is rotationally connected with a device body; a bearing at the bottom end of the worm is rotationally connected with a fixing plate; the fixing plate is fixedly connected with the device body; the front end of a worm gear is fixedly connected with a belt wheel; the worm gear and the belt wheel are rotationally connected with the lower end of a hanging rod; the upper end of the hanging rod is fixedly connected with the device body; the right end of the hanging rod is rotationally connected with a swinging arm; the right end of the swinging arm is rotationally connected with another belt wheel and the surface of the beltwheel is connected with a conveying belt in a rolling manner; and the lower part of the worm is fixedly connected with a first bevel gear. According to the agricultural swinging winnowing device, thedual functions of intermittent discharging and winnowing of a material guide pipe are realized through the swinging arm swinging vertically, grains dropping from the right side of the swinging arm areblown by a fan, dust and moldy powder in the grains enter a dust box through a filter plate, the grains are discharged through a discharge opening under the action of an oblique guide plate, and thusseparation of the grains and the moldy powder is realized. The agricultural swinging winnowing device is reasonable and applicable in structural design, is driven to winnow by a motor, and thus is high in automation degree, the winnowing efficiency is improved substantially, the labor is saved, and the winnowing effect is good.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to an agricultural swinging grain lifting device. Background technique [0002] Cereals include rice, wheat, millet, soybeans, etc., mainly containing seeds and fruits. They are the traditional staple food of many Asian people. As the traditional diet of Chinese people, grains have been one of the indispensable foods on the table of ordinary people for thousands of years. It occupies an important position in our country's diet and is regarded as a traditional staple food. Grains contain less fat, most of which are unsaturated fatty acids and a small amount of phospholipids. Grain germ oil contains more vitamin E, which has antioxidant effects. [0003] Since the grains are prone to mildew in rainy weather after maturity, and the grains are grown in the field, the harvested grains usually contain a lot of dust and mold powder. Most of the work is done manually, and some machines can also ...

Problems solved by technology

[0003] Since the grains are prone to mildew in rainy weather after maturity, and the grains are grown in the field, the harvested grains usually contain a lot of dust and mold powder. Most of the work is done manually, and some machines can also complete the work of raising grain, but most of them only remove large-scale sundries such as straw in the grain. For the removal of mold and ash, it is mainly done manually. The work efficiency is not high, the degree of automation is low, and the consumption A large workforce is not effective
