Self-weight-adjustable road-rolling structure
The invention discloses a self-weight-adjustable road-rolling structure which includes a roller and two sealing plates. The roller is a hollow cylinder body. The two sealing plates are respectively arranged at the two sides of the roller to form a sealed cylinder body with the roller. A shaft sleeve is arranged in the center of the roller. Two ends of the shaft sleeve are respectively fixed on the corresponding sealing plates, wherein one sealing plate is provided with a sand inlet and a sand outlet. The distance from the center of the sand inlet to the center of the shaft sleeve is larger than the distance from the center of the sand outlet to the center of the shaft sleeve. A detachable baffle is arranged on the sand outlet. The diameter of the baffle is larger than that of the sand outlet. In the invention, a roll shaft fit is formed between the shaft sleeve and the driving apparatus. The weight of the road-rolling structure is adjusted by means of addition or reduction of the quantity of sand in the roller, thereby satisfying different use requirement. The structure is reduced in cost and is reduced in engineering investment.
