Problems solved by technology

Therefore, the header has the disadvantages of poor adaptability to corn planting row spacing, low efficiency, high noise, easy to block, and poor reliability.
In order to solve the poor adaptability of row spacing, at present, the main method is to increase the opening angle between the reel chains to improve the adaptability of row spacing, but the effect is not ideal
Most of the stalk crushing devices on the harvester are hammer-claw type or swing-knife type, which consumes a lot of power, seriously breaks the soil and is difficult to front

Description

technical field [0001] The invention provides a chainless corn harvesting straw returning device, which belongs to the technical field of agricultural machinery. Background technique [0002] At present, the corn harvester headers all adopt the chain drive mode. During the corn harvesting process, the corn plants are fed to the corn ear picking device through the reel chain and the feeding chain. Therefore, the header has disadvantages such as poor adaptability to corn planting row spacing, low efficiency, high noise, easy blockage, and poor reliability. In order to solve the poor adaptability of the row spacing, at present, the main method is to increase the opening angle between the reel chains to improve the adaptability of the row spacing, but the effect is not ideal. Most of the stalk crushing devices on the harvester are hammer-claw type or swing-knife type, which consumes a lot of power, seriously breaks the soil and is difficult to front.
