AI Technical Summary
The existing header assembly of corn harvesters cannot adapt to double-row planting on wide ridges, resulting in inaccurate harvesting. It is necessary to replace it with an appropriate spacing assembly, which increases costs.
Design a device for adjusting the spacing of the header components. The header components are detachably connected to the crossbeam via a connecting block, and the movement and adjustment of the header components are achieved using a hexagonal drive shaft and a fixing ring, which is suitable for double-row planting on wide ridges.
It improves the convenience of corn harvesting, reduces replacement costs, and enables precise harvesting of corn with different row spacings.
