Concrete smoothing and trowelling machine

The utility model relates to the technical field of concrete construction, in particular to a concrete smoothing and trowelling machine. Comprising a bottom plate and a tow bar connected to the bottom plate, a motor box is fixedly arranged in the middle of the upper surface of the bottom plate, the motor box is provided with a side wall of an annular structure, and a vibration motor is fixedly installed in an inner cavity of the motor box; the front end of the tow bar is fixedly connected with two symmetrically-distributed forked rods, and the tail ends of the two forked rods are hinged to the left side and the right side of the side wall of the motor box respectively. A wiring terminal is arranged on the side wall of the motor box, and a power line of the vibration motor is connected to the wiring terminal. During construction, the trowelling machine is small in dragging resistance and high in trowelling quality, meanwhile, the weight of the pressing plate can be changed, and the trowelling machine is suitab
