Problems solved by technology

[0003] During the working process of the road roller, compacted materials often accumulate, which will lead to problems such as uneven road surface and uneven compaction density, which will affect the quality of the road surface. Therefore, it is generally necessary to pre-compact the road surface with a bulldozer or a grader. Leveling, which will increase the construction cost

Abstract

The invention discloses a road roller provided with a dozer blade, which comprises a road roller frame and the dozer blade arranged on the road roller frame, and the dozer blade comprises a dozer blade body and a support frame; one end of the dozer blade body is hinged to the support frame through a lifting rotating shaft, the other end of the dozer blade body is connected with the supporting frame through a lifting oil cylinder, and the lifting oil cylinder is connected with a hydraulic pump providing power through a pipeline and controlled by a lifting hydraulic valve. The road roller provided with the dozer blade has a left-right steering function, can effectively remove compaction materials, prevent material accumulation and improve flatness and compaction efficiency, has a floating function, can perform leveling and reduce energy consumption by utilizing the gravity of the dozer blade, and finally can ensure safety by means of a locking structure of the road roller in an unpoweredstate of the dozer blade.

Description

technical field [0001] The invention relates to a road roller equipped with a bulldozing blade, which belongs to the field of road rollers. Background technique [0002] Road rollers are widely used in filling and compacting operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. The roller uses the gravity of the machine itself to cause permanent deformation and compaction of the rolled layer. [0003] During the working process of the road roller, compacted materials often accumulate, which will lead to problems such as uneven road surface and uneven compaction density, which will affect the quality of the road surface. Therefore, it is generally necessary to pre-compact the road surface with a bulldozer or a grader. Leveling, which will increase the construction cost. Contents of the invention [0004] Aiming at the above-mentioned problems in the prior art, the present invention provides a road roller...
