The invention discloses a dumper front lifting belt trailer hydraulic control system which comprises a gas circuit, an oil circuit, a combined pneumatic control valve, a distribution valve, a reversing valve, a trailer oil cylinder and a dumper oil cylinder, and the combined pneumatic control valve is formed by combining an operating valve and a control valve; air inlets of the operating valve and the control valve are connected to an air inlet path, air outlets of the operating valve and the control valve are connected to an air outlet path, and an air outlet of the control valve is connected to the reversing valve; two air outlets of the operating valve are respectively connected to the left position and the right position of the distribution valve; an oil inlet of the distribution valve is connected into an oil inlet pipe of the oil tank, an oil return opening of the distribution valve is connected into an oil return pipe of the oil tank, an oil outlet of the distribution valve is connected into an oil inlet of the reversing valve, and two oil outlets of the reversing valve are connected into the trailer oil cylinder and the dumper oil cylinder respectively. The control valve is used for controlling the reversing valve to switch oil ways from the distribution valve, and it is guaranteed that the trailer oil cylinder and the dumper oil cylinder can independently achieve lifting and descending actions respectively. According to the invention, a dumper and a trailer container can be controlled by one set of power source.
