Full-hydraulic transmission amphibious rotary cultivator

A full-hydraulic transmission amphibious rotary cultivator comprises a frame, an engine, a hydraulic system, a crawler-type walking assembly and a rotary tillage assembly. The engine drives the hydraulic pump to operate, the hydraulic pump outputs high-pressure oil to the hydraulic system to drive the hydraulic motor to operate, and functional actions such as walking, rotary tillage and workbench rotation of the rotary cultivator are achieved. Full-hydraulic transmission is adopted, a clutch and a complex mechanical transmission system in a traditional structure are omitted, a transmission chain is shortened, the whole machine structure and operation are simplified, and the failure rate is greatly reduced. By operating the control valve, stepless speed change of walking and rotary tillage can be achieved, and functions and adaptability of the whole machine are improved. A multi-way valve is adopted to control the opening degree of the walking motor and the opening degree of the rotary tillage motor, so that t
