Technical Field

When working, it can cut down wheat stalks and spread them on the stubble to form overlapping ears of grain, which makes them easier to dry. As a grain harvesting machine, it is widely used.

[0003] The core structure of existing harvesters typically includes working components and a walking system. The working components include a reel mechanism and a cutter mechanism. The reel mechanism, cutter mechanism, and walking system are driven by three independent drive systems, which not only makes the structure redundant and complex, but also consumes a lot of energy.
