Concrete trowelling device

The utility model discloses a concrete trowelling device, which belongs to the technical field of concrete construction and comprises two fixing plates and a track seat, a transmission seat is connected between the two fixing plates, and a plurality of connecting toothed plates are movably connected to the lower wall of the transmission seat in a penetrating manner. A lifting mechanism for driving the connecting toothed plate to move up and down is arranged in the transmission seat; according to the scheme, the device can move along the track base, the whole machine does not need to be manually held for troweling, the working efficiency is high, the troweling is very stable during troweling, and the troweling effect is improved; the leveling mechanism can be driven to move up and down through the lifting mechanism, then the distance between the leveling mechanism and concrete can be adjusted according to the needed leveling height, the leveling requirements under different height conditions can be met, and th
