[0031] The above-mentioned embodiment has a simple structural design, but can solve the technical problems existing in the prior art. First, a filling port is opened on the roller end face for filling counterweights such as yellow sand or iron sand, so that the weight of the roller can be adjusted according to needs; second, the design of the traction bracket enables the walking wheels and the roller to be used under different requirements. The roller is used for roller pressing and the walking wheels are used for walking, solving the problem of walking on the road, and can walk normally following the speed of tractors, etc., without damaging the ground.
