Transmission mechanism of concrete stirring and transporting vehicle

The utility model relates to a transmission mechanism of a concrete mixing truck, which belongs to the field of the concrete mixing truck. The transmission mechanism is composed of an engine, a chassis frame, a belt pulley, a clutch, a gearbox, a duplex-chain chain coupling, a reducer and a bearing seat. The gearbox, the reducer and the bearing seat are respectively installed on the tilted turret of the chassis frame in sequence from bottom to top, the engine is connected with the gearbox through the belt pulley and the clutch, the gearbox is connected with the reducer through the duplex-chain chain coupling, and the reducer is connected with the bearing seat through the duplex-chain chain coupling. Because the engine of the transmission mechanism adopts a fractional-horsepower single-cylinder diesel engine to separately drive the tank body of the concrete mixing truck, the problems that the engine of the automobile cannot be switched off and the fuel oil is consumed when the prior hydraulic mixing truck wait
