Technical Field

[0001] The utility model relates to the field of down-the-hole drilling machines, in particular to a down-the-hole drilling machine with a positioning structure. Background Art

[0002] A down-the-hole drill is a device that allows an impactor to dive into a hole during the rock drilling process to reduce the energy loss caused by the impact work transmitted by the drill rod, thereby reducing the influence of the hole depth on the rock drilling efficiency. This type of drill uses compressed air as its power, and rotates and impacts to break the rock to form a hole. Down-the-hole drills are widely used in mining, railway and highway construction, water conservancy project construction, urban construction projects and other fields.
