Description

Technical Field

[0001] This utility model relates to drilling in soil or rock; in the field of mining technology, specifically to a drill core sampler assembly. Background Technology

[0002] A core drill, also known as a core drill, is a specialized piece of equipment that uses mechanical power to rotate a drill bit and extract cylindrical core samples from solid materials such as concrete, rock, asphalt, and wood. It is mainly used in fields such as material quality testing, geological exploration, and engineering surveying. Its core function is to obtain complete core samples through precise drilling, providing physical samples for subsequent strength analysis, composition testing, and structural evaluation.

An adjustment mechanism is provided on the second fixing block 4. The drilling direction of the drill rig 8 can be adjusted by the adjustment mechanism. The adjustment mechanism includes a first turntable 10, a first rotating rod 11, a limiting block 12, a first limiting hole 13, a fixing screw 14, a second limiting hole 15, a rotating ring groove 16, a rotating gear ring 17, a transmission groove 18, a second turntable 19, a second rotating rod 20, and a gear 21.

[0035] Furthermore, the first turntable 10 is installed on the front side of the second fixed block 4, the first rotating rod 11 is fixedly connected to the rear side of the first turntable 10, the rear end of the first rotating rod 11 extends rotatably into the interior of the second fixed block 4, the rear end of the first rotating rod 11 is fixedly connected to the front rotating column 6, the limiting block 12 is fixedly connected to the right side of the telescopic motor assembly 5, the first limiting hole 13 is opened on the front side of the second fixed block 4, the rear side of the first limiting hole 13 extends into the interior of the first fixed block 3, the fixing screw 14 is installed on the front side of the second fixed block 4, the rear end of the fixing screw 14 extends out of the first limiting hole 13, the rear end of the fixing screw 14 passes through the limiting block 12, the rear end of the fixing screw 14 extends into the first limiting hole 13 inside the first fixed block 3, the second limiting hole 15 is opened on the front side of the second fixed block 4, the second limiting hole 15 is located below the first rotating rod 11, the rear side of the second limiting hole 15 extends into the interior of the first fixed block 3, at the drilling rig 8 angle After adjustment, the second limiting hole 15 and the fixing screw 14 are threadedly matched to form a limiting fixation. The rotating ring groove 16 is opened on the upper side of the base 1. The rotating gear ring 17 is rotatably connected to the inside of the rotating ring groove 16. The upper side of the rotating gear ring 17 is fixedly connected to the first fixing block 3 and the second fixing block 4. The transmission groove 18 is opened inside the base 1.

[0036] Furthermore, when starting work, the device is moved by the movable wheels 2 on the lower side of the base 1, making it easy to move the device to the required working position. When drilling and core taking on the lower side, after the drill 8 is started, the telescopic motor assembly 5 drives the telescopic rod 7 to extend downward, driving the drill 8 to move vertically downward.
