Clean and efficient novel mining hydraulic excavator

Abstract

The invention discloses a clean and efficient novel mining hydraulic excavator. The hydraulic excavator comprises a body, wherein the body comprises a rotary platform which is arranged in the body, and a cab is a movably arranged in the body through the rotary platform; the body is movably provided with a movable arm through the cab in the body, and the end part of the movable arm is movably provided with a bucket rod through a movable arm pin shaft, shaft sleeves are nested at the joint between the outer end surface of the movable arm pin shaft and the movable arm, and a pin shaft baffle is fixedly inserted into the side end surface of the movable arm pin shaft, and the pin shaft baffle is connected with the movable arm through baffle rings; and a bucket is movably arranged at the bottomof the bucket rod, a bucket nozzle set is arranged at the position, close to the bucket, of the front end of the bucket rod, and the bucket nozzle set is fixedly arranged at a cross beam of the rotaryplatform, and the shaft sleeves and the baffle rings are made of high-molecular polyethylene materials. According to the clean and efficient novel mining hydraulic excavator, the structure is compact, and the use is convenient; and moreover, a dust removing device is arranged, the shaft sleeves on the pin shaft are improved, so that the problem of dust and noise pollution in digging operation canbe effectively solved, the working environment of workers is improved, the personal safety of workers is guaranteed, and the operation efficiency is effectively improved.

Description

technical field [0001] The invention relates to an excavator, in particular to a clean and efficient new mining hydraulic excavator. Background technique [0002] Hydraulic excavators are widely used in many fields such as earth and rock excavation, coal mining, etc., and are the main construction machinery. According to statistics, about 60% of the earth and stone volume in engineering construction is completed by excavators. Hydraulic excavators have a history of more than 140 years since the first manual excavator came out. During this period, it has experienced a gradual development process from steam-driven semi-rotary excavators to internal combustion engine-driven full-rotary excavators. Due to the application of hydraulic technology, there were suspended excavators equipped with hydraulic backhoes on tractors in the 1940s. In the early and mid-1950s, towed full-slewing hydraulic excavators and crawler-type full hydraulic excavators were successively developed. , Th...
