Harvester for astragalus sinicus seed collection and straw smashing and returning

Abstract

The invention discloses a harvester for astragalus sinicus seed collection and straw smashing and returning. The harvester comprises a machine body, an engine, an operation table, a transmission system, a harvesting assembly, a conveying assembly, a cleaning assembly, a threshing assembly, an air outlet assembly, a crawler belt assembly and a tightness adjusting assembly, and the engine, the operation table, the transmission system, the harvesting assembly, the conveying assembly, the cleaning assembly, the threshing assembly, the air outlet assembly, the crawler belt assembly and the tightness adjusting assembly are all arranged on the machine body. Compared with the prior art, the working procedures of cutting and dividing, threshing and separating, cleaning and straw smashing and returning can be achieved, the working efficiency is high, movably-connected material separating plates are arranged on the two sides of a cleaning bin, the air volume can be adjusted according to needs, and therefore the bin entering rate of astragalus sinicus seeds is guaranteed; and furthermore, a tightness adjusting device is arranged so as to meet the working requirements in different terrain environments, a good protection effect can be achieved on the caterpillar band, and the caterpillar band can keep good road holding force.

Description

technical field [0001] The invention relates to a harvester, in particular to a harvester for collecting milk vetch seeds and crushing straw for returning to the field. Background technique [0002] At present, the harvesting of milk vetch in my country basically stays at the stage of manual harvesting. When harvesting milk vetch, people will think of using a rapeseed combine harvester, but the rapeseed combine harvester is designed according to the size and weight of rapeseed particles. Due to the excessive air volume and the excessively large diameter of the sieve, milk vetch seeds and broken straws are discharged into the field together, which is not suitable for harvesting milk vetch. In view of this, the inventor of the present application has obtained a harvester for collecting milk vetch seeds and crushing straws for returning to the field through in-depth research. Contents of the invention [0003] The purpose of the present invention is to provide a harvester for...
