Description

Technical Field

[0001] The utility model relates to the technical field of drilling, in particular to a highway sound barrier drilling device with switchable drill bits. Background Art

[0002] Sound barriers, also known as noise barriers, are facilities installed on both sides of highways, mainly used to reduce the impact of traffic noise on the surrounding environment. Through the reflection, absorption and diffraction of sound barriers, the spread of noise can be effectively reduced, thereby protecting the quality of life of surrounding residents. Before installing highway sound barriers, holes must be drilled on the ground on both sides of the highway to facilitate the subsequent installation of highway sound barriers.

[0003] However, the existing highway sound barrier perforating device with switchable drill bit has the following disadvantages:

[0004] (1) The existing highway sound barrier drilling device with switchable drill bits has a weak function of quickly switching drill bits. When in use, the drill bit needs to be replaced after a long period of drilling. The drill bit replacement of the current drilling device is slow, resulting in a long time for replacing the drill bit and reduced work efficiency;

[0005] (2) The existing highway sound barrier punching device with switchable drill bits has a low punching efficiency. When in use, multiple holes must be punched in the ground before the highway sound barrier is installed. Currently, the punching device can only punch one hole at a time, resulting in a long punching time. Utility Model Content
