Problems solved by technology

[0003] In the prior art, the impact wheel rotates periodically. Every time it hits the ground, the stones and soil are compacted once, and the efficiency is slow. When the stones and soil are pressed, they will receive a relatively large impact force from the impact wheel. While compacting, its vibration will reduce the compacted density

Abstract

The invention discloses an impact roller, the structure of which comprises a vehicle body, wheels, impact wheels, auxiliary wheels and connectors, the body is equipped with wheels, the body and the impact wheels are installed and connected through the connectors, the impact wheels and auxiliary wheels are bonded, the auxiliary wheels It is installed and connected with the connector. The impact wheel is composed of an impact wheel frame, an impact inner wheel, a vibration-damping inner wheel, and a transmission inner wheel. The impact wheel frame is connected to the transmission inner wheel shaft. , the impact inner wheel includes a one-step pressure wheel, two pressure wheels, and three pressure wheels. The one-step pressure wheel has the same structure as the two pressure wheels and the three pressure wheels, and the three are assembled and connected. Once on the ground, the stones and soil are compacted once, and the efficiency is slow. When the stones and soil are compressed, they will receive a greater impact force from the impact wheel. The impact force will compact and the vibration will be reduced at the same time. compacted density.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to an impact roller. Background technique [0002] Vibratory rollers are widely used in road construction. They mainly rely on the periodic rotation of the impact rotation, and use their own gravity and vibration to compact various road construction materials. Most of the road construction materials are stones and soil. [0003] In the prior art, the impact rotation rotates periodically. Every time the ground is impacted, the stones and the soil are compacted once, and the efficiency is relatively slow. While playing the role of compaction, its vibration will reduce the density of compaction. Contents of the invention [0004] The main purpose of the present invention is to overcome the deficiencies of the prior art, and to provide an impact roller, so as to solve the problem of the periodic rotation of the impact wheel. Every time the impact on the ground is once, the stone...
