Straw processing system of stalk and ear harvesting type corn harvester

Abstract

The invention discloses a straw processing system of a stalk and ear harvesting type corn harvester. The straw processing system comprises a straw harvesting system, a field returning machine, a power transmission system and an engine, wherein the straw harvesting system comprises a lower header, a throwing fan, a secondary throwing part and a straw bin; and the engine is provided with a first power main output wheel, the first power main output wheel is in transmission connection with a first main output shaft belt wheel arranged on a main output shaft through a belt, a lower main shaft power transmission wheel and a returning machine power transmission wheel are further sequentially arranged on the left side of the main output shaft, the lower main shaft power transmission wheel is in transmission connection with a lower main shaft through a belt and a lower main shaft wheel, the lower header and the throwing fan are in transmission connection with the lower main shaft, and the returning machine power transmission wheel is in transmission connection with the returning machine. Power is transmitted to all working units of the corn harvester through one main output shaft, space is saved, arrangement of the transmission system of the whole corn harvester is facilitated, the power transmission stage number is reduced, and the transmission efficiency and reliability are improved.

Description

technical field [0001] The invention relates to the field of corn harvesters, in particular to a corn harvester stalk processing system with stem and ear harvesting. Background technique [0002] The straw processing system of the corn harvester with both stem and ear harvesting generally includes a straw harvesting system and a field returning machine. It is used to cut the straw from the root. The cut straw is transported to the crusher through the feeding device, and the crusher chops the straw. Under the action of the blower, the chopped grass is thrown to the grass bin through the throwing part for recycling. Utilization; the field returning machine is used to crush the root of straw and return it to the field. [0003] In the existing stalk processing system of corn harvester with both stem and ears, the engine generally transmits the power to the upper header, the large elevator, the peeling machine, the lower header, the feeding mechanism, and the crushing mechanism...

AI Technical Summary

Problems solved by technology

[0003] In the existing stalk processing system of corn harvester with both stem and ears, the engine generally transmits the power to the upper header, the large elevator, the peeling machine, the lower header, the feeding mechanism, and the crushing mechanism through multi-stage transmission. , throwing fan, etc., due to the high number of power transmission stages, resulting in large energy loss and low product reliability

In addition, the headers of existing corn harvesters with both stem and ear harvesting are generally unilaterally driven, and only one header shaft is used to drive all moving parts on the entire header, and an intermediate shaft connects several ear picking units. It is also connected with two small elevators, two auger mechanisms, and two straw chopping mechanisms. Due to the uneven force and load distribution, the intermediate shaft of the header is easy to bend and fail. Due to the small space of the header, Compact structure, very inconvenient for maintenance and replacement
