Agricultural efficient overturning winnowing device

Abstract

The invention discloses an agricultural efficient overturning winnowing device. A worm is rotationally connected to the upper end of a device body through a bearing, and the lower end of the worm is rotationally connected with a transverse plate. The transverse plate is fixedly connected with the device body. The upper portion of the worm is fixedly connected with a gear. The gear is engaged withan annular rack. The annular rack is fixedly connected with a rotation disc. The middle portion of the rotation disc is fixedly connected with the lower end of a stirring shaft. The lower portion of the stirring shaft is rotationally connected with the bottom of a storage box through a bearing, and the upper end of the stirring shaft is rotationally connected with a retainer. The retainer is fixedly connected with the side wall of the storage box. The middle portion of the stirring shaft is fixedly connected with a stirring bar. According to the device, the rotation disc is used for driving athrough hole in the circumferential direction of the rotation disc to communicate with an unloading pipe in a reciprocating manner for achieving intermittent discharging, the rotating stirring bar stirs grain in the storage box, and the situation that the grain is caked and is not discharged is prevented. A roller drives an overturning plate to rotate to scatter grain falling down from the throughhole in the surface of the rotation disc, and the grain is sufficiently scattered in air. The device is reasonable and applicable in structure design, the dust removing effect in the winnowing process is greatly improved, the automation degree is high, and labor is saved.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to an agricultural high-efficiency flipping and lifting device. Background technique [0002] Grains, as the traditional diet of the Chinese, have been one of the indispensable foods on the common people's table for thousands of years. They occupy an important position in the diet of our country and are regarded as the traditional staple food. Cereals include rice, wheat, millet, soybeans, etc., mainly containing seeds and fruits, and are the traditional staple food of many Asian peoples. 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 grain grows in the soil environment, the grain often needs to be dedusted after harvesting. At present, the most common way of dedusting is to raise the grain. Most of the existing means of raising the grain are t...

Problems solved by technology

[0003] Since the grain grows in the soil environment, the grain often needs to be dedusted after harvesting. At present, the most common way of dedusting is to raise the grain. Most of the existing means of raising the grain are to remove the dust by artificially raising the grain. Some grain raising machines cannot guarantee The grain is fully dispersed in the process of raising the valley, which makes the effect of raising the valley not good, and consumes a lot of labor, and the degree of automation is low
