Automatic troweling device

The utility model discloses an automatic troweling device. The automatic troweling device comprises a hopper, a troweling device and a pneumatic cylinder, wherein the pneumatic cylinder is connected with an air pump; the lower end of the cylinder body of the pneumatic cylinder is fixed on a support plate; rolling wheels are mounted at the lower end of the support plate; a supporting plate is arranged at the end extending out of the cylinder body of the piston rod of the pneumatic cylinder; the troweling device is fixed at one end of the supporting plate, and is connected with the hopper through a guide pipe. The automatic troweling device drives the troweling device to move up and down through the expansion and contraction of the pneumatic cylinder to realize automatic troweling, and realizes left and right moving of the troweling device through the rolling wheels at the lower end of the support plate; the material in the hopper is conveyed into the troweling device through a voltage motor; a troweling piece and a troweling head of the troweling device are connected with a groove through a convex, so as to be convenient to dismount and replace the troweling piece; a spiral rod is arranged in the guide pipe to convey the material more easily and quickly; the condition that the material is stuck on the guide pipe wall is reduced; meanwhile, re-stirring function is played; the automatic troweling device is time-saving and labor-saving, and greatly reduces the labor intensity of a worker.
