An adjustable grain winnowing device

Abstract

The invention discloses an adjustable type grain winnowing device and relates to the technical field of grain processing equipment. The adjustable type grain winnowing device comprises a rack; an outer tube is arranged on the top face of the rack; an inner tube is arranged inside the outer tube; a cavity is formed between the outer tube and the inner tube; a plurality of adhesive plates are evenlyand movably inserted in the side face of the outer tube in a penetrating mode; one ends of the adhesive plates abut against the outer surface of the inner tube; the bottom end of the inner tube penetrates through the rack and is connected with a discharging pipe; a plurality of air outlets are arranged on the side face of the inner tube in a matched mode; a wind conveying pipe is arranged insidethe inner tube; a plurality of sets of wind outlet pipes are evenly arranged on the outer surface of the wind conveying pipe; an adjusting mechanism is arranged at the top end of the inner tube; and the top of the adjusting mechanism is connected with a feeding hopper. As the outer tube and the inner tube are cooperatively connected and the adjusting mechanism is arranged in a matched mode, the winnowing effect is effectively improved, the production quality of grains is ensured, and the use cost of products is also lowered.

Description

technical field [0001] The invention belongs to the technical field of grain processing equipment, in particular to an adjustable 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 the force of gravity. So as to realize the separation of grain and impurities. When the grain winnowing machines in the prior art are winnowing the grains, the grains are usually poured in from the feeding port at one time, and then the grains are sorted through the winnowing mechanism. Due to the high density of grains passing through the winnowing mechanism in this design struc...
