Description

Technical Field

[0001] The utility model relates to the technical field of spiral drilling machines, in particular to a spiral drilling machine for engineering geological detection. Background Art

[0002] An auger drill is a type of spiral blade drilling machine, which mainly includes a drilling rig frame with a slideway and a reduction gearbox that can slide up and down along the slideway. The reduction gearbox is connected to a power input shaft and a power output shaft. The other end of the power input shaft is connected to a hydraulic motor, and the other end of the power output shaft is connected to a drill rod. The lower end of the drill rod is connected to a drill bit. It is usually used for engineering geological detection work.

[0003] The utility model patent application document with the announcement number "CN208934586U" discloses an engineering geological detection spiral drilling machine, which is mainly composed of a screw, a forward gear, a connecting barrel, a first fixed rod, a first gear and a second fixed rod. The technical solution is that the forward gear rotates clockwise, and the forward gear is connected to the first gear, and the first gear is connected to the second gear at the upper end, and the reverse gear rotates counterclockwise, and the reverse gear is connected to the second gear at the lower end. Therefore, the forward gear rotates clockwise by rotating the drill rod, and when the forward gear rotates clockwise, the reverse gear rotates counterclockwise, thereby driving the drill bit to drill counterclockwise, solving the problem that the rotation direction of the drill bit is the same as the rotation direction of the drill rod and the spiral blade has poor efficiency when drilling soil.

[0004] The engineering geological inspection spiral drilling machine disclosed in the above-mentioned document has the following defects: the drill bit of the engineering geological inspection spiral drilling machine will be worn during long-term use, thereby reducing the efficiency of subsequent work, and the drill bit of the above-mentioned engineering geological inspection spiral drilling machine cannot be quickly removed and replaced.

[0005] It can be seen from this that the existing engineering geological testing spiral drilling rig does not have a structure for quickly disassembling the drill bit, and it is necessary to improve the existing deficiencies and provide an engineering geological testing spiral drilling rig.
