Abstract

The invention discloses a novel grain winnowing device and relates to the field of agricultural machines. The novel grain winnowing device comprises a winnowing box and a material box, wherein the material box is arranged on the upper portion of the winnowing box and is in the shape of an inverse cone; an exhaust outlet is formed in one side of the winnowing box, a cylindrical air supply portion is arranged on the other side of the winnowing box, and a rotating shaft is arranged in the air supply portion in the axial direction and provided with paddles; one end of the rotating shaft stretches out of the air supply portion, a crank is arranged on the section, stretching out of the air supply portion, of the rotating shaft, and an air outlet is formed in the air supply portion and is consistent with the exhaust outlet of the winnowing box in direction; a feed inlet is formed in the bottom of the material box and stretches into the winnowing box, an adjusting plate is arranged along the feed inlet, a rotating rod is arranged on the side, close to the air supply portion, of the adjusting plate, and the adjusting plate can rotate around the rotating rod; a material collecting opening is formed in the bottom of the winnowing box, and an air deflector is obliquely arranged between the feed inlet and the exhaust outlet. The novel grain winnowing device is simple in structure, convenient to maintain, low in cost and suitable for small-scale family agricultural production.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a novel grain air separation device. Background technique [0002] Grain sorting is very critical in the process of agricultural production. It is related to whether high-quality grain can be obtained. Usually, the most effective way to sort grain is winnowing. In modern agriculture, large combine harvesters already have relatively mature productivity , the grain harvesting, sorting, and even drying are integrated on one machine, and the production efficiency is very high; or in plain areas, the harvester collects the grain and then dries it, and then sends it to the machine with a belt conveyor Go to a high place and use the natural wind to sort the grain. Although this method is low in cost and high in efficiency, it has regional limitations. In some hilly areas in the south, there is no natural wind in a continuous direction, and farmers are all small-scale production, w...
