Suction type multi-drum grain and impurity separating device

Abstract

The invention relates to a suction type multi-drum grain and impurity separating device which comprises a body, wherein the body is formed by two or more cavities through series connection. The cavities are communicated inside, and are identical or different in structure. One side of the upper portion of one cavity is provided with a large round drum communicated with a fan, and a small round drum is arranged in the large round drum in sleeved mode. A clearance used as a suction channel is formed between the inside of the large round drum and the small round drum, and a clearance used as a suction channel is formed between the bottom of the large round drum and the bottom of the small round drum. An opening in the bottom of the large round drum is connected with the fan, and at least one grain outlet is formed in the bottom of each cavity. A feeding inlet is formed in the upper face of one cavity, and the cavities are communicated through suction bent pipes. The suction type multi-drum grain and impurity separating device has the advantages of being simple and reasonable in structure, strong in practicability, convenient to manufacture, install and maintain, and good in using effect.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to an air-suction multi-barrel grain miscellaneous separation device used in conjunction with a comb-out combine harvester. Background technique [0002] The existing rice combine harvesters include full-feed and half-feed combine harvesters, most of which use grain reel, grain divider, header, walking mechanism, grain conveying device, threshing mechanism, grain screening mechanism, grain lifting mechanism, etc. Mechanisms and other complex working structures, the large and medium-sized combine harvesters of the above structure are not suitable for the actual production conditions of the mountainous and hilly landforms in southern and southwest China due to their complex structure, large volume, heavy weight, and high price; Small combine harvesters have low work efficiency and low work efficiency, can't achieve the effect of large and medium-sized harvesters, and can...

Problems solved by technology

[0002] The existing rice combine harvesters include full-feed and half-feed combine harvesters, most of which use grain reel, grain divider, header, walking mechanism, grain conveying device, threshing mechanism, grain screening mechanism, grain lifting mechanism, etc. Mechanisms and other complex working structures, the large and medium-sized combine harvesters of the above structure are not suitable for the actual production conditions of the mountainous and hilly landforms in southern and southwest China due to their complex structure, large volume, heavy weight, and high price; Small combine harvesters also have low work efficiency and low work efficiency, and cannot achieve the effect of large and medium-sized harvesters, and cannot adapt to the needs of different purchase groups and regions with different geographical conditions.
