Scraper

Abstract

The invention discloses a scraper comprising a chassis assembly, a traveling device assembly and a pitch oil cylinder. The chassis assembly comprises an engine and a chassis, wherein the chassis is provided with a scraper pan, a scraper knife is arranged below the scraper pan, and the rear end of the chassis assembly is hinged with the traveling device assembly through a first transverse hinge shaft; the lower end and the upper end of the pitch oil cylinder are respectively hinged with the traveling device assembly through a second transverse hinge shaft and a third transverse hinge shaft; and the projective points of the axes of the first transverse hinge shaft, the second transverse hinge shaft and the third transverse hinge shaft in a plane vertical to the axis of the first transverse hinge shaft form a triangle. Driven by the pitch oil cylinder, the scraper can transform states, wherein the scraper can scrape earth in one state and carry earth in another state, therefore the typesand the quantity of machines on the scraping-carrying work site can be reduced and the management of the scraping-carrying work site can be conducted conveniently.

Description

technical field [0001] The invention relates to earthwork construction technology, in particular to a scraper. Background technique [0002] With the rapid development of my country's economic construction, there are more and more types of construction machinery used in the field of infrastructure construction. In infrastructure construction such as embankment construction, reservoir construction, road construction, land reclamation, and post-flood silt cleaning, a large amount of earthwork needs to be shoveled through shoveling operations. [0003] At present, in the construction site of shoveling operation, the commonly used shoveling scheme is: first use bulldozers and other shoveling machines to accumulate the earthwork to be shoveled, and then load the earthwork to the carrier by the loader, and the carrier will The earthwork is transported to the designated location. [0004] Please refer to figure 1 , figure 1 It is a structural diagram of a bulldozer in the prior...

AI Technical Summary

Problems solved by technology

[0005] When the construction area of ​​the shoveling operation is large, using the current shoveling scheme, due to the limited shoveling distance of the bulldozer, the shoveled earth cannot be piled up at one time, so a large number of bulldozers and other shovels are required on the site of the shoveling operation. The coordinated operation of soil machinery, loaders and carriers has resulted in a wide variety of machinery on the construction site of the shoveling operation, resulting in complex on-site management of the shoveling operation, which in turn increases the difficulty of managing the shoveling operation site

In addition, in the existing shoveling scheme, the coordinated operation of various construction machinery also requires operators and logistics personnel of various construction machinery, which leads to more complicated on-site personnel for shoveling operations in the project, which also greatly increases the burden of shoveling. The difficulty of on-site management of the job
