Since the drill rod is used to drive the drill bit for construction operations for a long time, the drill bit is prone to severe wear and tear and needs to be replaced, and then the drill bit needs to be replaced conveniently to avoid the disadvantage that the drill bit cannot continue construction.

[0005] In order to solve the above technical problems, the utility model provides a mud wall drilling device for thick filling areas of mobile sand dunes, comprising: a drill rod, one end of the drill rod is fixedly connected to an auger rod, one end of the auger rod is installed with a drill bit, the auger rod is provided with an adjustment device at a position corresponding to the drill bit, the adjustment device comprises a butt joint tube, one end of the butt joint tube is fixedly connected to the auger rod, the position of the drill bit corresponding to the butt joint tube is fixedly connected to a fixed tube, the inner wall of the fixed tube is plugged with the surface of the butt joint tube, the inner wall of the fixed tube is fixedly connected with a mandrel, the end of the mandrel close to the butt joint tube is in a pointed cone shape, both sides of the circular arc surface of the butt joint tube are slidably penetrated by moving rods, the sides of the two moving rods close to each other are fixedly connected with extrusion blocks, the surface of the extrusion block is abutted with the surface of the mandrel, the positions of the moving rods on both sides of the inner wall of the butt joint tube are provided with inner cavity grooves, the depth dimension of the inner cavity grooves is adapted to the length dimension of the extrusion block, the circular arc surface of the moving rod is sleeved with a first spring, and the two ends of the first spring are respectively fixedly connected to the extrusion block and the bottom surface of the inner cavity groove.

[0006] The effect achieved by the above components is: when carrying out mud wall construction in the thick fill area of ​​mobile sand dunes, it will be necessary to use a drill rod to drill holes at designated locations. Since the drill rod is used to drive the drill bit for construction for a long time, the drill bit is prone to severe wear and needs to be replaced. At this time, in order to facilitate the convenient replacement and limiting of the drill bit, the top rod in the fixed tube on one side of the drill bit is connected and limited with the docking tube on the surface of the auger rod. First, pull the moving rods at both ends of the docking tube to allow the moving rod to drive the extrusion block to shrink into the inner cavity groove opened in the docking tube, and then plug the top rod in the fixed tube into the docking tube. At this time, release the moving rod to allow the moving rod to squeeze the position of the extrusion block through the pulling force generated by the first spring, so that the extrusion rod and the bottom end surface of the top rod are clamped and limited.

First, the rotating ring is threadedly connected to the fixed tube at one end of the drill bit, and then the connecting plates on both sides of the protective frame are plugged into the connecting blocks on both sides of the rotating ring. Then, the connecting rod is pulled to plug into the connecting plate in the connecting block.
