Harvesting unit body of small row spacing corn harvesting machine

Abstract

The invention relates to a harvesting unit body of a small row spacing corn harvesting machine, which comprises a plurality of groups of harvesting bodies and a straw cutter arranged on a header mounting bracket, wherein each group of the harvesting bodies comprises a pair of picking rolls, a pair of reeling devices arranged at the front end of the header mounting bracket, and a straw gripping conveyer arranged on the header mounting bracket between reeling outputs of each pair of the reeling devices and guide ends of the picking rolls. The harvesting unit body is characterized in that a bracket body of the header mounting bracket which is between the reeling outputs of each pair of the reeling devices of two adjacent groups of the harvesting bodies and the guide ends of the picking rollsand is provided with the straw gripping conveyer takes a symmetrical central line of the picking rolls of the two adjacent harvesting bodies as a reference to symmetrically tilt towards the central line, the center distance of two gripping input ends of adjacent straw gripping conveyers is kept between 350 and 450 millimeters, and two gripping output ends of the adjacent straw gripping conveyers correspond to the guide ends of the picking rolls respectively. The harvesting unit body of the small row spacing corn harvesting machine has the advantages of compact structure, low cost, reliable use and strong adaptability, and is suitable for harvesting small raw spacing corns.

Description

technical field [0001] The invention relates to harvesting of upright crops, in particular to a harvesting unit body of a corn harvester suitable for harvesting corn with small row spacing. Background technique [0002] At present, in other plain areas such as Inner Mongolia and the three northeastern provinces, the land is flat and the area is large, and the planting of corn is suitable for mechanized operations. Mechanized harvesting of corn harvesters with distance and rows. "A kind of knapsack type corn harvester with both stem and ears" announced in the CN2877247Y Chinese utility model patent specification applied by the applicant and announced on March 14, 2007 is also more suitable for the harvest of the above-mentioned 600-700mm row spacing corn. The "backpack type corn harvester with both stems and ears" in this public document includes a harvesting platform, an ear conveying and collecting device, a straw crushing and recycling device, and a power transmission dev...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the shortcomings of changing the distance between two adjacent groups of ear-picking rollers in the prior art, which cannot meet the requirements of use, adopting multiple pairs of picking and pulling rollers in different arrangements and matching different roller diameters, and high production costs, The invention provides a harvesting unit body of a small-row-spacing corn harvester
