Composite impurity removing all-in-one machine

Abstract

The invention relates to the field of agricultural machinery, and particularly relates to a composite impurity removing all-in-one machine. The composite impurity removing all-in-one machine comprises a rack, wherein an electric fan, a three-way pipe, a wind power elevator, a conveying pipe, a specific gravity hose and a specific gravity stoner are arranged on the rack; the wind power elevator comprises an elevating pipe and a volume chamber; the elevating pipe extends into the lower part of the volume chamber; a material blocking inclined plate A, a material blocking inclined plate B and a plurality of material blocking inclined plates C are arranged in the volume chamber; the material blocking inclined plate A and the material blocking inclined plate B are arranged in a staggered manner; the material blocking inclined plates C are arranged above the material blocking inclined plate B; and the material blocking inclined plates C are uniformly distributed on two sides by taking the central axis of the volume chamber as an axis. The different material blocking inclined plates are arranged in the volume chamber of the wind power elevator, so that the situation that grains are sucked out by the electric fan when being elevated to cause grain waste can be avoided, large and small impurities in the grains can be sucked out, the purpose of removing the large and small impurities is achieved, and the composite impurity removing all-in-one machine is complete in function and high in cost performance; and a grain homogenizing mechanism is arranged, so that the grains are uniformly dispersed and pass through a demagnetizing mechanism, and the demagnetizing effect is better.

Description

Technical field: [0001] The invention relates to the field of agricultural machinery, in particular to a compound cleaning all-in-one machine. Background technique: [0002] At present, most of the suction grain specific gravity de-stoners on the market are single specific gravity de-stoners, and a separate hoist is required, such as: a bucket elevator lifts the grain to the specific gravity de-stoner, and the specific gravity de-stoner also needs One air suction device, the combination of the two kinds of equipment can complete the grain lifting and stone removal. This kind of combined equipment has high energy consumption, uncompact structure, large floor area, increased user cost, and poor adaptability. Even if there is a combination of a wind hoist and a specific gravity destoner, another impurity remover is needed to remove the large and small impurities in the grain, and its function is not complete, and it cannot meet the needs of market development; and the existing ...
