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.
