A combined fan type oatmeal cleaning machine

Abstract

A combined fan type oat cleaning machine, including a frame, a feeding hopper, a screening assembly, a cleaning fan assembly, a grain conveying assembly and a power assembly, the screening assembly includes a plurality of cylinder screens arranged horizontally and parallel to each other, each The side walls of the cylindrical sieves are evenly opened with a plurality of screen holes, and the side walls of each cylindrical sieve are in the shape of waves composed of multi-section broken lines in the direction parallel to its axial direction. The direction of the wavy ups and downs on the side wall of the cylindrical screen is just opposite; the cleaning fan is composed of a parallel centrifugal fan and an axial flow fan, which are used to remove large impurities and small impurities respectively. A combined double blower fan and three cylindrical sieve oat cleaning machine of the present invention, through the change of the structure of multiple cylindrical sieves, and the cooperative interaction of different fans, the air separation of oat grains and impurities in oat raw materials is realized. The sieve group combination is fast and effective for screening and separation, thereby reducing production costs and improving the cleaning quality of oats.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment for cleaning oat extracts from crops, in particular to a combined double-fan type three-drum sieve oat cleaning machine. Background technique [0002] With the improvement of my country's agricultural production level, the development of mechanized harvesting of crops is also getting faster and faster. In recent years, the demand for oats in the grain market has been continuously increasing, but the matching oat cleaning device is immature in the market. The cleaning operation of oat extract is an important link in the oat harvesting process. The traditional cleaning of oats mainly relies on manual work. Although the cleaning is relatively clean, it is labor-intensive and inefficient. [0003] At present, most of the cleaning mechanisms on the market are vibrating sieve mechanisms composed of three sieves including a shaking plate, an upper sieve, and a lower sieve. Although the cl...
