AI Technical Summary
In existing wheat planters, the soil-crushing blades are prone to wear and breakage when trying to improve the soil-crushing effect, resulting in a shortened equipment lifespan.
The bevel gear transmission system driven by a servo motor, combined with the design of damping rods and shock-absorbing springs, drives the rotating shaft and the digging plate to efficiently break up soil through bevel gear meshing. The curved digging plate then continuously excavates, and the damping rods and shock-absorbing springs buffer the impact force to protect the stable operation of the transmission system.
It improves soil crushing efficiency, extends equipment life, avoids damage to the transmission system caused by impact, and ensures stable operation and efficient work of the equipment.
