Five-row longitudinal ear picking type ear and stem harvesting corn harvester header

Abstract

The invention relates to a five-row longitudinal ear picking type ear and stem harvesting corn harvester header. The header comprises a header body, an ear picking mechanism and a grain lifting mechanism are installed on the header body, the ear picking mechanism comprises five ear picking devices, and the grain lifting mechanism comprises five clamping feeding chains; each clamping feeding chaincomprises two grain lifting chains, and a plant channel is formed between the two grain lifting chains; and the corn harvester header further comprises a grain dividing device, the grain dividing device comprises six grain dividers, the grain dividers are arranged on the two sides of each plant channel respectively, the grain dividers are connected to the tops of the corresponding grain lifting chains in a lap joint mode, a distance between every two adjacent grain dividers is larger than a width of the corresponding plant channel, the front ends of the grain dividers form tips, and the frontends of the grain lifting chains are closer to the ear picking mechanism than the front ends of the corresponding grain dividers. According to the header, the tips are formed at the front ends of thedividers, so that the tips of the dividers can guide plants into corresponding plant channels more easily when the plants are not aligned.

Description

technical field [0001] The invention relates to the technical field of a corn harvester header, in particular to a corn harvester header with a five-row longitudinal arrangement for picking ears and stems. Background technique [0002] At the present stage, the headers of corn harvester with both ears and stems mainly include horizontal ear-picking double-layer headers and vertical ear-picking headers. [0003] Horizontal ear-picking double-layer headers are based on ordinary horizontal corn cob harvesters, adding straw collection, conveying, and chopping devices to the bottom of the header, because horizontal headers are more sensitive to corn planting patterns in different regions , especially the planting row spacing of corn, the dry and wet thickness of the straw, and the height of the ears and sticks will seriously affect the operation effect. The cutting platform is easy to be entangled with grass and blockage. When the height of the stick is too low, the ear cannot e...

[0003] Horizontal ear-picking double-layer headers are based on ordinary horizontal corn cob harvesters, adding straw collection, conveying, and chopping devices to the bottom of the header, because horizontal headers are more sensitive to corn planting patterns in different regions , especially the planting row spacing of corn, the dry and wet thickness of the straw, and the height of the ears and sticks will seriously affect the operation effect. The cutting platform is easy to be entangled with grass and blockage. When the height of the stick is too low, the ear cannot enter the harvesting channel, and it is easy to enter the lower layer of the horizontal double-layer harvesting platform for ear picking, that is, enter the forage, causing food loss; at the same time, the horizontal double-layer harvesting machine for ear picking The lower layer collects corn stalks. During the cutting and feeding process, the stalks will carry some debris into the cutting platform, including foreign objects such as weeds, soil, and stones. Straw chopping device is damaged, affecting the operation

[0004] CN201410127856.5 discloses a vertical corn harvester, the feeding inlet of which clamps the feeding chain is small, and when encountering the situation of wrong harvesting, it is easy to push the rod, which reduces the efficiency of the corn harvester
