The invention provides a novel monoblock pump box structure which comprises a pump box body. The section of the pump box body is of a V-shaped structure, a plurality of monoblock pump mounting holes are formed in the two sides of the V-shaped structure and penetrate through the pump box body, and a machine body mounting hole and a monoblock pump fixing hole are further formed in the end face of the V-shaped structure. The outer side of the V-shaped structure is provided with a diesel oil inlet channel, a diesel oil return channel, an engine oil inlet channel and an engine oil return channel which are integrally formed in the axial direction, and the diesel oil inlet channel, the diesel oil return channel, the engine oil inlet channel and the engine oil return channel are each provided with an oil channel communicated with the monoblock pump mounting holes. According to the pump box structure, the rigidity and the strength of the pump box are improved, meanwhile, the pump box and a machine body are integrally
