AI Technical Summary
Existing tractor multi-way valve control levers are difficult to limit effectively and reliably in bumpy and vibrating environments, affecting the stability and reliability of hydraulic output.
A multi-way valve control lever positioning mechanism is designed, including a housing, a rotating shaft assembly, a control handle, a positioning slot, and a limiting part. By rotating the limiting part of the positioning slot, the control handle can enter or exit the travel path of the control handle. The limiting spring is used to limit the rotation angle, thereby fixing and locking the control handle.
It enables the control handle to remain in a fixed position under bumpy and vibrating conditions, making operation convenient and highly reliable, and improving the stability and reliability of the hydraulic system.
