Transmission system with corn upper header

Abstract

The invention discloses a transmission system with a corn upper header which comprises an upper header, a lower header and a header power shaft. The header power shaft is in transmission connection with an engine. The upper header comprises an upper header auger, a small elevator and an ear picking mechanism, wherein the small elevator and the ear picking mechanism are arranged in front of the upper header auger and are both driven by the header power shaft. An upper header auger driving wheel and a driving gear are sequentially arranged on the header power shaft and transmit power to the upper header auger and a header upper driving shaft respectively, a gearbox transmission wheel and a small elevator transmission wheel are further arranged on the header upper driving shaft and transmit power to the ear picking mechanism and the small elevator respectively, the power transmission level is low, energy loss is small, and the product reliability is high.

Description

technical field [0001] The invention relates to the field of corn harvesters, in particular to a corn upper header transmission system. Background technique [0002] Stem and ear harvesting type corn harvester header consists of an upper header for ear harvesting and a lower header for straw harvesting. The upper header includes an ear-picking mechanism and an auger. The ear-picking mechanism picks off the ears and twists The dragon transports the grain conveyor to the corn harvester. [0003] The existing upper cutting platform generally adopts left and right two long chains to pull out the corn stalks, and then the ears of corn picked by the ear picking rollers are transported to the entrance of the large elevator through the auger. For example, ZL201420562973.X pulls the corn stalks to the ear picking rollers through the left and right pulling chains to pick the ears, and the picked ears are transported to the large elevator through the pulling chains for subsequent proc...

AI Technical Summary

Problems solved by technology

First of all, this structure adopts a group of chains for pulling up grains and ears to transport, the speed of pulling up grains and ear ears is the same, and cannot be adjusted separately. On the one hand, the lifting speed of fruit ears cannot be further improved, and the lifting speed is relatively slow. The efficiency is low; on the other hand, when the density of corn stalks is different, the speed of weeding and the conveying speed of ears cannot be effectively coordinated, and the ears cannot be quickly lifted to the large elevator, and the accumulation of corn ears is easy to occur, resulting in equipment failure

[0004] In addition, the existing headers of the corn harvester with both stem and ear harvesting generally transmit the power to the ear picking mechanism, the upper header auger, etc. through the multi-stage transmission of the main input shaft of the header. Due to the high number of power transmission stages , leading to large energy loss and low product reliability
