Overhead bendable half-feeding combined harvester

Abstract

The invention relates to an overhead bendable half-feeding combined harvester. The harvester comprises a harvesting platform; the harvesting platform is provided with a seedling straightening mechanism, a cutter mechanism, a clamping, bending and conveying mechanism and a threshing cylinder; the clamping, bending and conveying mechanism comprises a clamping and threshing conveyor chain, a bendingchain and a grass discharging chain, wherein the clamping and threshing conveyor chain, the bending chain and the grass discharging chain are consistent in running speed; the seedling straightening mechanism is used for straightening plants positioned incorrectly, and the adjusted plants enter a space between the seedling straightening mechanism and the clamping, bending and conveying mechanism; meanwhile, the upper parts of the plants are restrained by the bending chain, the lower parts of the plants are restrained by the grass discharging chain, and the roots of the plants are cut off by thecutter mechanism; along with the movement of the bending chain and the grass discharging chain, the upper parts of the plants are bent by the bending chain, a closed zone is formed in a horizontal plane between every two adjacent bending fingers of the bending chain, and the bending fingers rotate clockwise to bend the plants onto clamping chain teeth of the clamping and threshing conveyor chain,so that the plants are controlled by the clamping and threshing conveyor chain and brought into an inlet of the threshing cylinder; the lower and upper parts of the plants are threshed at a constantspeed in parallel under the restraining effect of the grass discharging chain.

Description

technical field [0001] The invention relates to the technical field of half-feed combine harvesters, in particular to an upper-mounted bending half-feed combine harvester. Background technique [0002] The Chinese invention patent with the publication number CN103039207A discloses a chain conveying mechanism for two-way clamping and bending of a combine harvester. The outer side of the chain plate is provided with horizontal chain teeth perpendicular to the outer chain plate, and a bending guide, which uses the horizontal chain teeth of the two-way clamping chain to drive the crops to run, and uses the bending guide to guide the cone to bend the plants obliquely into the vertical Straight chain teeth, realize the upper part of the plant is sent to the drum for threshing. The Chinese invention patents whose publication numbers are CN104145615A and CN104396435A have also all adopted the same clamping and bending conveying chain provided with transverse sprockets.

Problems solved by technology

[0003] However, the reciprocating direction of the clamping and bending conveyor chain is opposite, and the running trajectory of the reciprocating stroke must be separated enough in the vertical direction to prevent the horizontal sprocket of the chain of the reciprocating stroke from contacting the plant at the same time, affecting the normal movement of the plant; Moreover, the structure of the harvester using the clamping and bending conveying chain of the above-mentioned structure is relatively complicated and takes up a large space, which is a necessary passage for the lower end of the plant to run.

The volume of the lower end of the plant is much larger than that of the upper end of the plant, and a slight lag can easily cause blockage and affect the operation process
