Stripping type combine harvester

Abstract

The invention relates to a stripping type combine harvester. A blade type crop-poking device is arranged at the front end of a harvester frame; the harvester frame is provided with upper and lower double-roller type threshing devices behind the blade type crop-poking device; a vibrating sieve and a grain receiving hopper are arranged below the upper and lower double-roller type threshing devices; a lower threshing roller is connected to the vibrating sieve and the grain receiving hopper through an eccentric wheel in a manner of a motive power; an upper threshing roller is connected to the blade type crop-poking device in a manner of the motive power; a rotary spiral roller stem-crushing device is arranged on the harvester frame and below the vibrating sieve and the grain receiving hopper; a back threshing roller is arranged on the harvester frame and behind the upper and lower double-roller type threshing devices; the vibrating sieve and the grain receiving hopper are arranged below the back threshing roller; an air suction hole is arranged at the bottoms of both the vibrating sieve and the grain receiving hopper; the air suction hole is communicated with a multi-cylinder grain and sundry separation device through an air suction pipe, so that the grains and the sundries enter into the multi-cylinder grain and sundry separation device for separation through the air suction pipe; the grains are discharged from a grain outlet for bagging; and the sundries are blown away from a draught fan opening.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and relates to a combing type 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 also have low work efficiency, cannot achieve the effect of large and medium-sized harvesters, and cannot adapt to the needs of different purchasing groups and regions with different geographical conditions. ...
