Multi-cut-flow soybean combined harvester

Abstract

The invention relates to a multi-cut-flow soybean combined harvester, and belongs to the technical field of agricultural machinery. The multi-cut-flow soybean combined harvester comprises a header located at the front end of a walking chassis. The output end of the header is connected with a screening and cleaning device on the walking chassis through a gap bridge device. The gap bridge device comprises a plant feeding belt at the front end of a gap bridge support. The output end of the plant feeding belt is connected with a multi-concave sieve composed of a first concave sieve, a second concave sieve and a third concave sieve. A plant feeding roller is installed above the plant feeding belt. A thread rod threshing roller, a plate type threshing roller and a spike tooth threshing roller are installed above the first concave sieve, the second concave sieve and the third concave sieve respectively. A bean conveying belt is installed below the multi-concave sieve. By arranging the threshing devices on the upper portion of the gap bridge conveying device through the cut flow mode, threshing and conveying are organically combined and spatially overlapped, and therefore the size of the combined harvester can be greatly reduced, and the combined harvester is suitable for irregular mountainous regions with small rice field parcels.

Description

technical field [0001] The invention relates to a harvester, in particular to a multi-cut flow soybean combine harvester, which belongs to the technical field of agricultural machinery. Background technique [0002] The typical structure of the existing combine harvester for bean crops is known by the Chinese patent literature named "Small Soybean Combine Harvester" with application number 201510505965.0 and "A Self-adaptive Cleaning Crop Harvester" with application number 201910162868.4 public. The basic structure of this type of combine harvester is that the front end of the walking chassis supports the header, and the threshing equipment is placed in the middle and rear. The threshing equipment consists of an axial flow main threshing drum, a concave screen located under the axial flow main The vibrating screen is composed of a vibrating screen, and the header and the threshing equipment are connected by a bridge conveying mechanism. After the header completes the harve...

Problems solved by technology

[0003] However, the above-mentioned existing combine harvesters for bean crops are difficult to use in hilly and mountainous areas where fields are generally small and irregular due to their large volume.

As far as the applicant knows, manual harvesting is still necessary in areas such as hilly and mountainous areas, which is costly and labor-intensive
