Stalk and ear harvesting type corn harvester

Abstract

The invention discloses a stalk and ear harvesting type corn harvester which comprises an upper header, a large elevator, a peeling machine, a lower header, a throwing fan, a returning machine and an engine; and a first power main output wheel is arranged on the engine, the first power main output wheel is in transmission connection with a main output shaft through a belt, a peeling machine power transmission wheel is further arranged on the right side of a first main output shaft belt wheel, the peeling machine power transmission wheel is in transmission connection with a peeling machine power shaft, a lower main shaft power transmission wheel and a returning machine power transmission wheel are sequentially arranged at the other end of the main output shaft, the lower main shaft power transmission wheel is in transmission connection with a lower main shaft, the upper header, 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 stem and ear harvester corn harvester. Background technique [0002] Stem and ear harvester corn harvester generally includes corn harvesting system, straw harvesting system and field return machine. The corn harvesting system includes upper header, large elevator, peeling machine and granary. The upper header is used to pick corn ears. Next, the picked ears are transported to the peeling machine by the large elevator, and the peeled ears are peeled by the peeling machine, and the peeled ears are transported to the granary; The feeding part and the grass bin, the lower cutting platform is used to cut the straw from the root, and the cut straw is transported to the crusher through the feeding device, and the crusher chops the straw, and the chopped grass is thrown through the blower under the action of the throwing fan. The sending part is thrown to the grass bin for recycling; t...

AI Technical Summary

Problems solved by technology

[0003] The existing stem and ear harvesting corn harvester generally transmits the power to the upper header, the large elevator, the peeling machine, the lower header, the feeding device, the crusher, and the blower through the multi-stage transmission of the engine. etc. Due to the high number of power transmission stages, the energy loss is large and the product reliability is low

In addition, the existing corn harvester headers are generally unilaterally driven, and only one header shaft is used to drive all moving parts on the entire header. An intermediate shaft not only connects several ear picking units, but also connects two small The elevator is also connected with two auger mechanisms and two straw chopping mechanisms. Due to the uneven force and load distribution, the intermediate shaft of the header is easily bent and fails. Because the header space is small and the structure is compact, it is easy to repair and replace. extremely inconvenient
