Description

Technical Field

[0001] The utility model relates to the technical field of engineering drilling, in particular to a road drilling machine used in municipal road engineering. Background Art

[0002] During the construction of municipal road projects, it is necessary to drill holes in the ground using a road drilling machine in order to understand the underground rock and soil conditions. By drilling a hole and taking out underground rock and soil samples, we can intuitively and clearly understand the mechanical properties, distribution levels and depth of the underground rock and soil, as well as the groundwater conditions.

[0003] After a road drilling machine has drilled a hole in the ground, mud will adhere to the drill shaft of the drilling machine. If the mud on the drill shaft is not cleaned, the mud will become dry and hard over time, and the ground where the drilling machine is stored will be covered with mud and dust. Existing drilling machines have a simple structure and do not have the function of cleaning the drill shaft. Workers often use water guns and other equipment to clean the drill shaft after work. Therefore, after using the drilling machine, it is necessary to push it to a place with water for cleaning, which is inconvenient to use and has certain limitations. Utility Model Content
