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...
