Furthermore, the hydraulic motor is fixedly arranged on the material receiving/storing hopper through a bearing seat, a tapered roller bearing is arranged in the bearing seat, and an inner ring of the tapered roller bearing supports an output shaft of the hydraulic motor.

Further, the front end of the frame chassis is fixedly provided with a cross beam, the cross beam is fixedly connected with two cantilever longitudinal beams, the front ends of the cantilever longitudinal beams are fixedly provided with shafts, the shafts are rotatably provided with push rollers for pushing the concrete mixer through bearings, and the cantilever longitudinal beams are fixedly provided with the material receiving/storing hopper through screws.

Compared with the prior art, the utility model discloses the make full use of space can realize the conveying of concrete stirring material, prevents that conveying process from solidifying. The shaftless spiral auger is used for conveying, the structure is compact, the torque is large, the speed is adjustable, the automatic production efficiency is high, and the production cost is low. Especially, the rear end of the shaftless spiral auger is not fixed, so that the shaftless spiral auger can freely swing in a certain range in the U-shaped groove, and the shaftless spiral auger has self-adaptability and is not easy to block materials when large aggregate concrete is conveyed. And the shaftless spiral auger is easy to produce, wear resistant, long in service life and convenient to maintain in daily life, and is suitable for severe working environment in a coal mine.
