Linkage-mechanism excavator

Abstract

A linkage-mechanism excavator is characterized in that one end of a first connecting rod is connected onto a rack; the other end of the first connecting rod is connected with one end of a second connecting rod; the other end of the second connecting rod is connected onto a bucket; one end of a third connecting rod is connected to the rack; the other end of the third connecting rod is connected with one end of a fourth connecting rod; the other end of the fourth connecting rod is connected to the bucket; one end of a first telescopic rod is connected to the rack; the other end of the first telescopic rod is connected onto the first connecting rod; one end of a second telescopic rod is connected onto the rack; the other end of the second telescopic rod is connected on the third connecting rod; one end of a fourth telescopic rod is connected onto the rack; the other end of the fourth telescopic rod is connected onto a first sliding block; the first sliding block sleeves the fourth connecting rod; one end of a third telescopic rod is connected onto the first sliding block; and the other end of the third telescopic rod is connected onto the second connecting rod. According to the linkage-mechanism excavator provided by the invention, the complete machine structure is simple and compact, and the part manufacturing and machining requirements are low; and the linkage-mechanism excavator can play a relatively good role in a severe-environment and narrow-space construction site as well as an accident rescue scene where rapid excavation, obstacle clearance and flattening are required.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a link mechanism type excavator. Background technique [0002] An excavator, also known as an excavating machine, is an earth-moving machine that uses a bucket to excavate materials that are higher or lower than the bearing surface, and load them into transport vehicles or unload them to the stockyard. The materials excavated by the excavator are mainly soil, coal, sediment, and pre-loose soil and rock. Judging from the development of construction machinery in recent years, the development of excavators is relatively fast, and excavators have become one of the most important construction machinery in engineering construction. The common excavators on the market adopt the structure of boom, boom and bucket connected in series, and the oil cylinder is integrated on each arm. This design makes the boom play the role of excavating force and carrying the weight of the bucket at the same time...

AI Technical Summary

Problems solved by technology

The common excavators on the market adopt the structure of boom, boom and bucket connected in series, and the oil cylinder is integrated on each arm. This design makes the boom play the role of excavating force and carrying the weight of the bucket at the same time. The oil cylinder of the boom has high performance requirements, which affects the improvement of the bucket capacity and operating weight
