Header for stalk and ear harvesting type corn harvester

Abstract

The invention discloses a header for a stalk and ear harvesting type corn harvester, which comprises an ear harvesting header, a straw harvesting header and a header power shaft, wherein the header power shaft is in transmission connection with an engine; the ear harvesting header comprises an upper header auger, a small elevator and an ear picking mechanism which are arranged in front of the upper header auger and driven by the header power shaft; the straw harvesting header comprises a lower header auger and a swing box; and a swing box driving belt wheel, a lower header auger driving wheel, an upper header auger driving wheel and a driving gear are sequentially arranged on the header power shaft and transmit power to the swing box, the lower header auger, the upper header auger and the 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, the 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 harvester header of a corn harvester with both stems and ears. Background technique [0002] The corn harvester header of both stem and ear harvesting is composed of an upper header for ear harvesting and a lower header for straw harvesting. The upper header includes an ear picking mechanism and a auger. The dragon is transported to the grain transporter of the corn harvester; the lower header includes a swing knife and a auger. The swing knife cuts the stalk from the root and transports it to the straw crushing mechanism through the auger. [0003] Existing ear harvesting headers generally use two long weeding chains on the left and right to remove corn stalks, and then the corn ears picked by ear picking rollers are transported to the entrance of the large elevator through the auger. For example, ZL201420562973.X, which pulls the corn stalks to the ear picking rollers thr...

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 stem and ear corn harvester headers generally transmit the power to the ear picking mechanism, upper header auger, oscillating knife and lower header auger in sequence through the multi-stage transmission of the header main input shaft. Long et al, due to the high power transmission series, resulting in large energy loss and low product reliability
