NOVELTY - The compost processing machine comprises an alternating current servo motor, a stacking device, a shaft lifting device, and a movement device. The movement device is mounted on a wheel hub of the servo motor for driving the motor to forward and backward direction. The stacking device is mounted on a front position of a dumper body. The shaft lifting device is provided with a turning shaft for rotating the compost, and is mounted on one side of the servo motor. The turning shaft is connected with the movement device. An external power source is set with the servo motor.    USE - Compost processing machine.    ADVANTAGE - The compost processing machine has reduced power consumption and weight, simple structure and high operation efficiency, generates less pollution, and is easy to operate.    DETAILED DESCRIPTION - The compost processing machine comprises an alternating current servo motor, a stacking device, a shaft lifting device, and a movement device. The movement device is mounted on a wheel hub of the servo motor for driving the motor to forward and backward direction. The stacking device is mounted on a front position of a dumper body. The shaft lifting device is provided with a turning shaft for rotating the compost, and is mounted on one side of the servo motor. The turning shaft is connected with the movement device. An external power source is set with the servo motor. The turning shaft is provided with a vent hole. A pile shaft is provided with the vent hole. The servo motor comprises a first servo motor, and a second servo motor. A screw component is connected with the pile shaft. A slide block device is connected with a sliding groove of a machine body. The machine body is connected with the pile shaft. An air pump is provided with the first servo motor and the pile shaft. A third servo motor is mounted on the machine body, and is provided with a wheel belt and a synchronous belt. A ball screw rod is connected with the turning shaft and the machine body. A thrust bearing is fixed on the ball screw rod. The synchronous belt and the wheel belt are mounted on a balancing device. The balancing device includes an overrunning clutch, a self-lock equipment, and a housing. The self-lock equipment includes a friction ring. The overrunning clutch includes a lower external ring. A bush presses the friction ring. The bearing is provided with the groove. A friction force between the lower external ring and the friction ring is adjusted by application of pressure. The movement device comprises a first front wheel, a second front wheel, a support frame provided between the first front wheel and the second front wheel, a first wheel hub motor, a second wheel hub motor, and an electric assembly for driving the first and second wheel hub motors.
