PROBLEM TO BE SOLVED: To provide a mixer drum driving device capable of driving a mixer drum by an electric motor without causing reduction in transport efficiency.SOLUTION: A mixer drum driving device as problem solution means includes: a mixer drum M rotatably mounted on a frame C of a truck mixer V; and a driving source D for rotationally driving the mixer drum M. The mixer drum M is mounted on the frame C at a forward inclined attitude in which a rear end side is lifted upward. The driving source D includes an electric motor 3 provided in a rear section of the frame C. A plurality of drum rollers R are provided to abut on a roller ring 2 provided on a rear outer periphery of the mixer drum M and rotationally support the mixer drum M from a lower side. The electric motor 3 rotationally drives the drum rollers R so as to rotationally drive the mixer drum M by driving sprockets 6 provided on rotary shafts r of the drum rollers R via a speed reducer 4 and a roller chain 7 or a belt wound around auxiliary wheels w provided between the speed reducer 4 and the sprockets 6 and between each sprocket 6 and each sprocket 6.SELECTED DRAWING: Figure 1 |
