The invention discloses an unloading power conversion device of a vehicle-mounted 380V motor-driven concrete mixer truck. The unloading power conversion device comprises a stirring tank, a power conversion device and a discharging mechanism. The stirring tank is arranged on a chassis through a fixer. A hydraulic motor connected with a rotating shaft is arranged at one end of the stirring tank. Thehydraulic motor is connected with the power conversion device through an oil pipe. The power conversion device comprises a four-stage motor, a control electric box, a speed reducer, a variable oil pump, a first oil way switching valve and a second oil way switching valve. A rotating shaft of the four-stage motor is connected with the speed reducer through a connector, and the speed reducer is connected with the variable oil pump. The variable oil pump is connected with the first oil way switching valve through a first oil pipe and a second oil pipe, and the first oil way switching valve is connected with the hydraulic motor through a third oil pipe and a fourth oil pipe. The unloading power conversion device of the vehicle-mounted 380V motor-driven concrete mixer truck is used for solvingthe problems that the prior concrete mixer truck is large in energy consumption, high in production noise and serious in tail gas pollution in the discharging process.
