A new type of road roller

Abstract

The invention provides a novel road roller and particularly relates to the technical field of construction machinery. The novel road roller comprises a road roller body, wherein one end of the road roller body is provided with a rolling compaction device and the other end of the road roller body is provided with a dust collection device; the rolling compaction device comprises a main roller grooveand an auxiliary roller groove; a main roller and an auxiliary roller are respectively arranged in the main roller groove and the auxiliary roller groove in a movable manner; a roller shaft is movably arranged in the auxiliary roller; the auxiliary roller is movably arranged on the roller shaft; the road roller body is movably provided with an adjusting rod; one end of the adjusting rod is movably connected with the roller shaft and the other end of the adjusting rod is also provided with a gear; the dust collection device comprises a dust collection box, a dust suction device and a dust suction pipe; the dust collection box is arranged at the other end of the road roller body; the dust suction pipe is connected with the dust suction device; the dust suction pipe is provided with a scraper; and the side wall of the road roller body is provided with an edge compaction device. The novel road roller has the advantage that edges of a roadbed can be rolled and compacted without causing theshift of the center of gravity of the road roller when the road roller compacts the edges.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a novel road roller. Background technique [0002] Existing road rollers can't roll the "three backs" of structures and the edges of high-fill embankment. The compaction of these edges can only be compacted with small tamping machines, but the compaction speed is slow, the effect is poor, and the labor intensity is high. Therefore a kind of practical technology is very important to solve the problem of roadbed edge compaction: 1. The main reason why the road roller cannot press the roadbed edge is that the steel wheels of the road roller are all installed in the frame, and when the road roller rolls the edge roadbed of the structure, the structure and the machine Frames interfere with each other in space, and the steel wheels cannot be close to the structure, resulting in a lack of pressure in the subgrade; 2. When the road roller rolls the edge of the high-fill su...

Problems solved by technology

[0002] Existing road rollers cannot reach the edges of the "three backs" of the structure and the high-fill embankment. The compaction of these edges can only be compacted with a small tamping machine, but the compaction speed is slow, the effect is poor, and the labor intensity is high.

Therefore a kind of practical technology is very important to solve the problem of roadbed edge compaction: 1. The main reason why the road roller cannot press the roadbed edge is that the steel wheels of the road roller are all installed in the frame, and when the road roller rolls the edge roadbed of the structure, the structure and the machine Frames interfere with each other in space, and the steel wheels cannot be close to the structure, resulting in a lack of pressure in the subgrade; 2. When the road roller rolls the edge of the high-fill subgrade, due to the lack of pressure at the edge of the multi-layer earthwork, the slope earthwork is relatively soft, and the edge of the road roller is prone to appear.
