Header for stalk and ear harvesting type corn harvester

Abstract

The invention discloses a header for a stalk and ear harvesting type corn harvester. The header comprises an ear harvesting header, a straw harvesting header and a lower main shaft, wherein the ear harvesting header comprises a left small elevator, a right small elevator, a left small auger, a right small auger, a left ear picking mechanism and a right ear picking mechanism; the left ear picking mechanism comprises a first left ear picking unit, a left middle ear picking unit and a second left ear picking unit, and the right ear picking mechanism and the left ear picking mechanism are symmetrically arranged; the first left ear picking unit comprises a first left gearbox, and the second left ear picking unit comprises a second left gearbox; and the left small elevator, the left small auger and the left ear picking mechanism are in transmission connection with a left first shaft of the header, and the right small elevator, the right small auger and the right ear picking mechanism are in transmission connection with a right first shaft of the header. The problems that a transmission chain of an existing header is prone to heating and breaking, a transmission shaft is prone to bending, and transmission reliability of the header is not high are solved, and the header is more reasonable in transmission arrangement, even in load distribution, stable in operation and high in reliability.

Description

technical field [0001] The invention relates to the field of corn harvesters, in particular to a header for a corn harvester with both stem and ear harvesting. Background technique [0002] The feeding method of the rear side of the front cutting knife in the existing stem and ear harvesting platform is a rake chain structure, and its main structure is that a flat tube is installed on the top of the two chains, and the flat tube is dragged by the rotation of the chain to move. Drive the straw backward to achieve the purpose of feeding, but because there are large gaps between adjacent chains and adjacent flat tubes, the straw is easy to fall from the gap, the loss rate is high, and the machine harvesting income drops seriously. [0003] The existing corn harvester header is generally unilaterally driven, and is only transmitted to all moving parts on the entire header through a header intermediate shaft. An intermediate shaft is connected to several ear picking units and als...

Problems solved by technology

[0002] The feeding method of the rear side of the front cutting knife in the existing stem and ear harvesting platform is a rake chain structure, and its main structure is that a flat tube is installed on the top of the two chains, and the flat tube is dragged by the rotation of the chain to move. Drive the straw backward to achieve the purpose of feeding, but because there are large gaps between adjacent chains and adjacent flat tubes, the straw is easy to fall from the gap, the loss rate is high, and the machine harvesting income drops seriously

[0003] The existing corn harvester header is generally unilaterally driven, and is only transmitted to all moving parts on the entire header through a header intermediate shaft. An intermediate shaft is connected to several ear picking units and also connected to two small liters. The conveyor 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, maintenance and replacement are extremely difficult. inconvenient
