The invention relates to a concrete transportation device which is composed of a supporting rack, a track, a track limiting sensor, a position recognition device, a hopper box, a mounting plate, a mounting rack, a feeding plate, a feeding baffle plate, a feeding limiting sensor, a feeding shaft, a feeding decelerator, a feeding motor, a walking trolley, a guide wheel, a guide shaft, a driving wheel, a driving shaft, a driving motor, a driving decelerator, a safe collision-prevention device, a limiting guide wheel, a limiting fixing device and a limiting connecting device. The invention belongsto the field of building equipment. The concrete transportation device has the beneficial effects that the feeding device can control the emptying amount and the emptying speed according to production requirements automatically; when the feeding plate rotates to discharge materials, the feeding limiting sensor will limit the rotating position of the feeding plate to prevent instability of the feeding plate; provided with the safe collision-prevention device, a concrete transportation hopper in a walking process can stop automatically in case of obstacles or other unforeseen circumstances.
