Hydraulic system of clearance machine and barrel type hydraulic transmission conveyor

The invention relates to the technical field of mining machinery, in particular to a hydraulic system of a clearance machine and a barrel type hydraulic transmission conveyor, which are applied to the clearance machine. The hydraulic system of the clearance machine comprises a power pump, a multi-way control valve and a power output end, wherein the power output end drives a material collecting stranding cage arranged on the clearance machine to collect materials and drives a spiral conveyor to convey materials; and the multi-way control valve is provided with an inlet part connected with the power pump and a plurality of output control parts connected with the inlet part, and the output control parts synchronously or independently provide power for the material collecting stranding cage and the spiral conveyor through the power output end and control the magnitude of power according to the load of the power output end. The hydraulic system of the clearance machine has the beneficial effects that through the
