Abstract

The invention discloses an excavator for building machinery, and relates to the technical field of buildings. The excavator for the building machinery comprises a cab, wherein the bottom of the cab is fixedly connected to a machine body platform, the left side of the cab is fixedly connected to a machine box, the top of the machine box is rotationally connected to a lower lifting arm, and the top of the lower lifting arm is fixedly and rotationally connected to a connecting rod through a fixing base. A through groove is provided at the bottom of the machine body platform, space inside the through groove can be used for containing a fixing plate and a fixing mechanism, the fixing plate and the fixing mechanism are placed in the through groove to prevent dust falling when not used, the fixing mechanism slides out of the through groove when used, the contact area between the whole machine and the ground can be increased through internal parts, road holding force is higher, front-back shaking force generated by the machine body when a gripper works is reduced, the driving comfort of a driver is improved, and when a slope is encountered, the use safety of the machine can be improved by using the mechanism, so that the working efficiency of the machine is further improved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to an excavator for construction machinery. 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 three most important parameters of an excavator are: operating weight (mass), engine power and bucket capacity. [0003] Because the gravity of the bucket of the excavator will increase when it is working, it will drive the entire body of ...
