Road roller capable of automatically adjusting water yield

Abstract

The invention discloses a road roller capable of automatically adjusting the water yield. The road roller comprises a road roller body, steel wheels and a water tank spraying water to the steel wheels. A water outlet is formed in the water tank. A plug is made in the water outlet. An elastic piece is arranged on the plug. A water outlet groove is formed in the middle of the plug and divides the plug into an upper plug body and a lower plug body. A plurality of through holes are formed in the lower plug body. A pushing rod is arranged under the water outlet. A torsional spring is further arranged on the water tank. Air resistance suffered by the water tank is changed when the driving speed of the road roller is changed, so that the water tank rotates by different angles; after the water tank rotates, the pushing rod under the water outlet of the water tank pushes out the plug in the water outlet; the water yield of the water tank is adjusted according to the communicating area of the water outlet groove on the plug and the water tank to achieve variable water outlet of the water tank; and the structure is simple and convenient.

Description

technical field [0001] The invention belongs to the field of road engineering machinery and equipment, and in particular relates to a road roller for automatically adjusting water output. Background technique [0002] Road rollers belong to the category of road equipment in construction machinery. They are widely used in the filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can roll sandy, semi-cohesive and cohesive soils, Subgrade stabilized soil and asphalt concrete pavement layer. When rolling asphalt concrete pavement, due to the adhesiveness of asphalt, it is necessary to spray water on the steel wheel to form a water film on the steel wheel to prevent the asphalt concrete from adhering to the steel wheel, which will cause the road surface to be not smooth due to the adhesive material during rolling. smooth. However, the existing technology cannot discharge water accor...

Problems solved by technology

When rolling asphalt concrete pavement, due to the adhesiveness of asphalt, it is necessary to spray water on the steel wheel to form a water film on the steel wheel to prevent the asphalt concrete from adhering to the steel wheel, which will cause the road surface to be not smooth due to the adhesive material during rolling. smooth

However, the existing technology cannot discharge water according to the speed of the road roller, and can only manually adjust the water discharge, which is very inconvenient
