Description

Technical Field

[0001] This utility model relates to the field of rotary drilling rig technology, specifically a rotary auxiliary slag removal rig. Background Technology

[0002] Rotary drilling rigs are construction machines suitable for hole-forming operations in building foundation engineering. The rock drill bit used in rotary drilling rigs is a special type of drill bit, whose main advantage is its fast drilling speed. However, there are also many problems during construction. One of the most troublesome issues is that after drilling, the gravel and clay inside the hole tend to stick together and clog the drill bit, making it difficult to quickly remove the rock and soil debris, thus reducing construction efficiency and slowing down the project progress.

[0003] For example, a rotary auxiliary slag-cleaning cylinder drill with patent document number CN216197875U includes a vertical cylinder. Slag-cleaning structures are equidistantly installed on the top of the vertical cylinder. The slag-cleaning structures include a vertical rod, a sleeve plate, and a vertical pole. The upper outer wall of the vertical rod is rotatably connected to the top of the vertical cylinder, and the outer wall of the vertical rod is welded equidistantly to the inner wall of the sleeve plate. The top of the vertical rod is welded to the bottom of the vertical pole. In this rotary auxiliary slag-cleaning cylinder drill, the rotating vertical rod drives the sleeve plate to rotate, loosening the compacted soil inside the vertical cylinder. This allows the soil to fall out of the vertical cylinder, facilitating cleaning, increasing loosening points, reducing effort, and lowering the difficulty of use. The rotating sleeve drives the screw to move inward, allowing the inner side of the screw to insert into the interior of the cylinder, reinforcing the output end of the inserted power equipment, improving connection stability, ensuring normal use, and facilitating widespread adoption.

[0004] However, the above-mentioned mechanism has the following problems: First, when the drill bit is drilling, the internal vertical rod and sleeve do not rotate, and the soil in the center is not disturbed, which increases the resistance of drilling and reduces drilling efficiency. Second, when the drill bit is drilling, if the center part encounters hard rocks or other debris, the vertical rod may bend or break, affecting drilling and cleaning. Third, the drill bit needs to be pulled out for cleaning each time, resulting in low drilling efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a rotary auxiliary slag cleaning cylinder drill to solve the problems existing in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotary auxiliary slag removal cylinder drill, comprising a cylinder drill, a drill bit disposed below the cylinder drill, and a base disposed above the cylinder drill. The outer ring of the cylinder drill is provided with uniformly distributed slag removal threads. The cylinder drill is characterized in that: a central rod is provided in the center of the cylinder drill, a central drill bit is provided below the central rod, and a large number of uniformly distributed side vertical rods are provided on both sides of the central rod. At the same time, the cylinder drill is provided with uniformly distributed slag removal holes.

[0007] Furthermore, a second gear is provided above the central rod, and a first gear is provided above each of the side vertical rods. The second gear meshes with the first gears around the perimeter.

[0008] Furthermore, a side drill bit is provided below the side vertical rod, and a dragon is wrapped around the outer ring of the side vertical rod.

[0009] Furthermore, the lower surfaces of both the center drill bit and the side drill bit are covered with conical protrusions.

[0010] Furthermore, the central rod extends through the base and is driven by a separate motor.

[0011] This utility model has the following beneficial effects: First, the center rod and the side rod are both located below the drill bit and can rotate together with the barrel drill to break up the soil and improve drilling efficiency; second, the barrel drill is equipped with a discharge hole, and the auger inside the barrel drill discharges the soil from the discharge hole; third, it can greatly reduce the number of times the barrel drill needs to be removed, thus improving drilling efficiency.
