The invention provides a pressure wheel component for an efficient exhaust road bridge roller and belongs to the field of engineering machinery. The pressure wheel component solves the problem of existing road rollers that air in soil can not be exhausted completely. The pressure wheel component comprises a pressure wheel, wherein a plurality of caulking grooves are formed in the outer wall of the pressure wheel, air outlet rods are arranged in the caulking grooves, a first magnet is fixed to the rear end of each air outlet rod, an annular groove is formed in the rear end of each air outlet rod and sleeved with a spring, and the two ends of each spring are connected with the corresponding air outlet rod and the bottom of the corresponding caulking groove respectively; each spring pulls the corresponding air outlet rod to enable the air outlet rod to be located in the corresponding caulking groove and the front end of the air outlet rod to be flush with the outer wall of the pressure wheel, and a cylindrical sliding chute is arranged in the pressure wheel. The pressure wheel component further comprises an arc-shaped sliding plate arranged in the sliding chute, wherein a balancing weight and a second strip-shaped magnet are arranged on the sliding plate, the balancing weight can drive the sliding plate to be located under the sliding chute all the time, and the second magnet can repel the magnet in the corresponding caulking groove in front in the advancing direction of the pressure wheel and make the corresponding air outlet rod to stretch out of the caulking groove. By the adoption of the pressure wheel component, construction quality can be improved.
Description
technical field [0001] The invention belongs to the technical field of engineering machinery, and relates to a high-efficiency air exhaust road and bridge roller roller assembly. Background technique [0002] As construction machinery, road rollers can roll sandy, semi-cohesive and cohesive soils, subgrade stabilized soils, and asphalt concrete road surfaces, and are widely used in filling and compacting operations for large-scale engineering projects such as roads, railways, airport runways, dams, and stadiums. . [0003] Existing road rollers can only use rollers to compact the surface of the land. Due to the limited extrusion force, the air inside the land cannot be fully squeezed out, and the compaction effect is poor. Therefore it is necessary to improve. Contents of the invention [0004] The object of the present invention is to solve the above-mentioned problems in the prior art, and provide a high-efficiency air-exhausting roller assembly for road and bridge roa...
