Adjustable bulldozing device for road construction

Abstract

The invention discloses an adjustable bulldozing device for road construction. The adjustable bulldozing device structurally comprises a bulldozing roller, a bulldozing shovel, movable arms, movable side plates, an upper cover, a sliding device and a lifting device. The bulldozing roller is arranged in front of the bulldozing shovel, and the bulldozing roller and the bulldozing shovel are in parallel with each other. The movable side plates and the upper cover constitute a cover body structure. According to the adjustable bulldozing device for road construction, a positioning shaft, a positioning rod and a fixing transverse rod are matched to achieve lifting positioning, and during the period, a hydraulic shock absorber assists to conduct damping; after lifting positioning, a lifting movable chain drives a pushing device to move up and down to achieve rising and falling of the bulldozing roller, during rising and falling, horizontal positioning is achieved, and the stability is good; asliding plate drives the whole to move, positioning after distance moving is achieved through a position column, laying, strengthening and buckling are achieved through an upper layer plate and a lower layer plate, an auxiliary sliding plate is used for controlling the sliding speed of the auxiliary sliding plate, and thus the bulldozing shovel can freely stretch out and draw back; and the distance between the bulldozing device and the top surface is overall advantageously adjusted during bulldozing according to the road conditions, and high-quality and efficient bulldozing is achieved.

Description

technical field [0001] The invention is an adjustable bulldozer for road construction, which belongs to the field of bulldozers. Background technique [0002] The rapid development of the construction industry, the cleaning of roads and other garbage in the early stage, and the cleaning of heavy snow on the northern roads have become the primary tasks, which will greatly promote the development of construction machinery in China. However, in current bulldozers, the working device generally has problems such as difficulty in lifting and telescopic adjustment, and poor adaptability to working conditions. Therefore, an adjustable bulldozing working device is needed. [0003] The prior art discloses the application number: 201610188935.6, a high-performance bulldozing device, including a cab, a hydraulic rod, a bulldozing bucket, a beam, a column, a vibrating plate, a driving track and an engine energy recovery device, and the bulldozing bucket It is connected to the cab throug...
