Abstract

The invention discloses a novel telescopic bucket rod structure of a loader-digger. The novel telescopic bucket rod structure comprises an outer bucket rod, an inner bucket rod and a telescopic oil cylinder. The inner bucket rod is arranged inside the outer bucket rod in a hinged mode through the telescopic oil cylinder, and the two ends of the telescopic oil cylinder are connected with the rear hinged point of the outer bucket rod and the rear hinged point of the inner bucket rod respectively through a second hinge pin and a first hinge pin. Guide grooves are formed in the two sides inside the outer bucket rod respectively, and an inclined sliding block is arranged in each guide groove. Upper sliding blocks are arranged on the upper portions of the inclined sliding blocks respectively and movably installed on the two sides inside the outer bucket rod through fixed bolts and spring washers, sliding rail inclined blocks are welded on the two sides of the inner bucket rod respectively and installed between the inclined sliding blocks and the upper sliding blocks, the inclined surfaces of the sliding rail inclined blocks are in sliding fit with the inclined surfaces of the inclined sliding blocks, and the upper end faces of the sliding rail inclined blocks make contact with the upper sliding blocks. According to the novel telescopic bucket rod structure, the bucket rods of the loader-digger does not need to be frequently replaced, a large amount of working time is saved, working efficiency is improved, and the application range of the whole loader-digger is also greatly widened.

Description

technical field [0001] The invention relates to a telescopic arm structure, in particular to an excavating loader telescopic arm structure, which belongs to the field of engineering machinery. Background technique [0002] Backhoe loader is a new type of multi-functional engineering machinery integrating excavation and loading. It is widely used in road maintenance, farmland construction, pipeline laying, cable laying, landscaping and excavation and crushing of cement roads. It has been in the international construction machinery market for many years. occupy a considerable share. In order to meet the market demand, backhoe loaders have higher and higher requirements in terms of applicability, especially in terms of the influence of the performance of the excavation working device on the performance of the whole machine. The stick length of the traditional backhoe loader excavating working device is fixed. Although there are extended sticks to meet the needs of users to a c...
