Description

Technical Field

[0001] The utility model relates to the technical field of drilling rigs, in particular to a pneumatic crawler type drilling rig. Background Art

[0002] Existing drilling rig technology mostly uses positioning for drilling. However, in this method, the drilled materials cannot be discharged during the drilling process, which is easy to cause blockage. For example, a Chinese patent discloses "a pneumatic crawler drilling rig" with an application number of "CN202223554171.8". It uses a movable plate to drive the spring slot to move. The spring slot cooperates with the inner wall of the box to compress the spring. The movable plate drives the connecting plate to move downward, and the connecting plate pushes the fixed plate to move downward. The fixed plate drives the conical block out of the slot hole, and the fixed plate allows the conical block to be inserted into the soil, thereby achieving the purpose of active positioning. However, when it is in use, the drilled materials cannot be discharged, which affects the drilling effect and affects the drill bit. Utility Model Content
