Ear lifting system of stalk and ear harvesting type corn harvester

Abstract

The invention discloses an ear lifting system of a stalk and ear harvesting type corn harvester, which comprises a small elevator and an upper header auger which are arranged on an ear harvesting header, and the small elevator is arranged at the front end of the upper header auger; the front end of a large elevator is communicated with the upper header auger, and the rear end of the large elevator is communicated with the husker; a main shaft power output belt wheel and a husker transmission chain wheel are arranged on a main shaft; the main shaft power output belt wheel is in transmission connection with the small elevator and the upper header auger; and the husker transmission chain wheel is in transmission connection with the large elevator. The chain scraper conveyor type small elevator is adopted to replace a traditional seedling pulling chain to lift ears, the lifting speed is not limited by the seedling pulling speed and can be reasonably adjusted, the ears can be quickly lifted to an inlet of the large elevator, the lifting efficiency is high, the limitation of the sizes of the ears is avoided, the small ears can be lifted to the large elevator as well, and the lifting quality is high.

Description

technical field [0001] The invention relates to the field of corn harvesters, in particular to an ear lifting system of a corn harvester with both stem and ear harvesting. Background technique [0002] The ear elevating system of the existing stem and ear corn harvester generally only includes a large elevator for one elevating, and the elevating speed is slow and the efficiency is low. The corn harvester of the ear lifting system that comprises two lifts has occurred on the market at present, and it comprises the little lifter on the ear harvesting header and the traditional big lifter to carry out secondary lift. The ear harvesting platform picks off the corn ears through the ear picking mechanism, and the ears enter the auger under the movement of the pulling chain, which is a lift; the ears in the auger further enter the large elevator, and pass through the large elevator. It is lifted to the peeling machine for subsequent processing, which is the second lift. [0003]...

AI Technical Summary

Problems solved by technology

[0003] The existing corn ear lifting system has slow lifting speed and low efficiency, and its pulling chain needs to pull the grass at the same time, which further reduces its lifting speed; the conveyor chain is equipped with a conveying plate, but the conveying plate directly Integrated on the conveyor chain, the conveyor plate is easy to wear, and cannot be disassembled and replaced after wear, which is inconvenient for maintenance. The conveyor chain needs to be replaced as a whole, which increases maintenance costs

Moreover, the conveyor chain is generally made of relatively hard material, which has a greater impact on the ear, which may easily cause the grains on the ear to fall off and reduce the quality of the ear.

[0004] In addition, the transmission system of the harvesting table using the pulling chain and the transmission system of the existing large elevator are complex in structure, occupy a large space, have many transmission stages, low transmission efficiency, and high energy consumption, which affects the income of corn.
