Blowing type lifting separating device for combine harvester

Abstract

The invention relates to a blowing type lifting separating device for a combine harvester. The blowing type lifting separating device is provided with an air inlet pipe which is communicated with a draught fan, the other end of the air inlet pipe is communicated with one end of an air flue at the bottom of a material collection hopper, the other end of the air flue at the bottom of the material collection hopper is connected with an air outlet pipe, a grain and impurity discharge opening is formed in the upper end of the joint of the air flue and the air outlet pipe, the grain and impurity discharge opening is communicated with the air flue and the air outlet pipe, the other end of the air outlet pipe is communicated with a grain and impurity separating device, and a spiral conveying device is arranged at the bottom of the grain and impurity separating device. The blowing type lifting separating device is simple and reasonable in structure, strong in practicability, convenient to manufacture, install and maintain, and good in use effect.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to a wind-blown lifting and separating device used on a 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't adapt to the needs of different purchasing grou...

[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.
