Abstract

A sludge removing device of a hydraulic excavator comprises a push oil cylinder, a crank, a connecting rod, a sludge removing barrel, a screw, a piston and a mast. A hinge point at one end of the push oil cylinder is movably connected with the mast, a hinge point at the other end of the push oil cylinder is movably connected with the crank, a hinge point at one end of the crank is movably connected with the mast, a hinge point in the middle of the crank is movably connected with the push oil cylinder, a hinge point at the other end of the crank is movably connected with the connecting rod, a hinge point at one end of the connecting rod is movably connected with the crank, a hinge point at the other end of the connecting rod is movably connected with the sludge removing barrel, the piston is fixed on the mast through the screw, and the mast is movably connected with a movable arm and a bucket rod oil cylinder of the excavator. According to the principle of a crank sliding block mechanism, sludge in a pit of a building foundation is removed through the hydraulic excavator, and the sludge removing device of the hydraulic excavator has high efficiency, speedy performance, reliability and wide practicability.

Description

technical field [0001] The invention relates to a mud clearing device for a hydraulic excavator, which realizes the excavator clearing the mud in deep pits of building foundation piles, and has high efficiency, quickness and strong reliability. Background technique [0002] At present, China's urbanization process is accelerating, and the number of infrastructure buildings is huge. With the rising cost of labor, the trend of mechanization replacing manpower is obvious. A large number of foundation piles and deep pits cleaned by manpower need to be mechanized to improve efficiency and reduce costs. Moreover, for some pits with small diameter and deep depth, it is not easy to carry out mud cleaning work manually. Contents of the invention [0003] The problem to be solved by the present invention is to provide a mud clearing device for a hydraulic excavator that can easily and quickly clear the mud in deep pits of building foundation piles. [0004] In order to solve the ab...
