Description

Double-cone axial-flow threshing and separating device of harvester

Technical Field

The utility model relates to a double-cone axial-flow threshing and separating device of a harvester, in particular to a double-cone axial-flow threshing and straw removing separator of a harvester.

Background

Most of the prior domestic combine harvesters adopt a combined tangential flow cylinder threshing and straw separator or a full axial flow threshing separator, but the structural design is unreasonable, and the combined tangential flow cylinder threshing and straw separator has the advantages of small tangential flow threshing cylinder threshing area, single harvested crops, small feeding amount and large engine load. The grain breaking rate of the grain threshing of the tangential flow roller is high during normal harvesting, the grain cannot be completely threshed when crops are wet, the grain is entrained by the straws, the grain discharging hole of the traditional straw separator is fixed, the crop straws are easily inserted into the hole to cause blockage, the grains cannot be normally separated from impurities, the grain runs out of the straw separator, when the straw separator separates the grains, the grains fall onto a flat plate at the bottom of the straw separator through the grain discharging hole, the grains are separated from the impurities once and slide out of the straw separator simultaneously to form accumulation, the grains fall onto a sieve, when cleaning, the grains are separated from the impurities with small air volume, the grains are greatly lost with large air volume, when the grains are wet, the grains are easily adhered to the bottom flat plate and are difficult to clean, when the harvester harvests on one side on a sloping field, the grains are entrained when the crop pile is discharged, the separation is not thorough, when the harvester harvests on the sloping field, the angle of the straw separator is increased, the straw is difficult to discharge, the, when the full axial flow threshing and separating device is used for drying crops, the full axial flow threshing and separating can crush crop grains and straws, when the crops are wet, due to the fact that the separating time is limited, the crops cannot be separated well, threshing and cleaning loads are large, harvesting loss is caused, the comprehensive utilization of crop straw recycling is increased in the prior art, the straws are crushed, and the fact that the straw length can not bundle the crops and can not be recycled is greatly difficult. The multifunctional harvester with one machine has high threshing efficiency and unbroken straw.
