Description

Watering device for road roller Technical Field The utility model belongs to the technical field of road rollers, and particularly relates to a water sprinkling device for a road roller. Background The single steel wheel vibratory roller is widely applied to various engineering scenes requiring high-strength compaction by virtue of the characteristics of strong exciting force and high compaction efficiency, and is particularly suitable for compaction operation of soil roadbed and soil-stone mixed filling roadbed, thereby providing a solid foundation for subsequent pavement of asphalt surface layers or cement concrete surface layers. When the single steel wheel vibratory roller is operated, if the water content of roadbed soil is too low, the inter-particle internal friction force is large, the prescribed compactness can be difficult to achieve, and a plurality of raised dust can be generated, and the surrounding environment is influenced, so that the roadbed soil needs to be sprayed with water for wetting, after the roadbed soil is wetted, when the single steel wheel vibratory roller is driven by staff to compact the roadbed, the steel wheel of the roller can be adhered with impurities such as soil, and therefore, the sprinkling device for the roller is needed, and the sprinkling device can be used for sprinkling water on the roadbed pavement and the steel wheel of the roller, so that the roadbed compaction, the raised dust inhibition and the excessive impurity adhesion prevention on the steel wheel of the roller are facilitated. Disclosure of utility model The utility model aims to provide a water spraying device for a road roller, which can spray water on a foundation pavement and a road roller steel wheel, so as to be beneficial to compacting the foundation, inhibiting dust and preventing excessive impurities from adhering to the road roller steel wheel, and solve the problems in the prior art. The technical scheme includes that the sprinkler for the road roller comprises a connecting plate arranged on the top of the road roller, wherein the connecting plate is in rotary connection with the road roller through a rotary shaft, a spraying pipe is fixedly connected to the inner wall of the connecting plate, a water inlet of the spraying pipe penetrates through the top of the connecting plate, a plurality of nozzles distributed at equal intervals are arranged in an inner cavity of the connecting plate, the nozzles are in threaded connection with a water outlet of the spraying pipe, a water tank is mounted on the surface of the road roller, a water pump is fixedly mounted on the surface of the road roller, a water outlet of the water tank is fixedly connected with a water suction pipe through a flange, the water suction pipe is fixedly connected with the water pump through a flange, a water inlet of the spraying pipe is in threaded connection with a water delivery pipe, the water delivery pipe is fixedly connected with the water pump through a flange, limit sleeve is fixedly connected to the inner walls on the left side and the right side of the connecting plate, two limit seats are fixedly connected to the surface of the road roller, one of the limit seats is provided with a plug pin, and the top of the plug pin penetrates through the limit sleeve.
