AI Technical Summary
The existing rotary tiller leveling mechanism requires multiple hydraulic rods to adjust the angle and width of the tiller blade, resulting in high energy consumption and easy damage to the tiller blade, which affects its service life.
The seven-shaped frame uses bearings to rotate and support the connecting frame and extension plate on the mounting block. The flat shovel can be adjusted adaptively, reducing the need for drive components. Combined with the fixing method of mounting bolts and inserts, it is easy to disassemble and maintain.
It achieves energy-efficient and high-performance leveling operations, extends equipment lifespan, and improves maintenance convenience.
