Description

Technical Field

[0001] The utility model relates to the field of geological drilling devices, in particular to a geological drilling device for geological surveying. Background Art

[0002] Drilling is an important technical means in geological exploration. A drill rig drills downward from the surface, creating a cylindrical borehole in the ground to identify and delineate strata. Core, ore, and soil samples can be obtained from various depths within the borehole for analysis and research, determining the physical and mechanical properties and indicators of rock and soil layers to inform design requirements. Drill rigs are primarily categorized into rotary and percussive types.

[0003] For example, the patent document with the announcement number CN217712432U discloses a geological drilling device for geological surveying, including a pressurized water bottle, a water pipe, a handle, a gasoline engine, a water injection port, a rotating rod, a drill bit, a docking rod, and a support frame. The water injection port is connected to the pressurized water bottle through a water pipe, and the rotating rod and the drill bit are coaxially installed at the lower end of the water injection port. The support frame is inserted into the pin hole position at the rear end of the gasoline engine outer frame through the docking rod. A geological drilling device for geological surveying, this device is suitable for drilling and sampling operations on slope surfaces. After assembling the drilling machine and the support frame, the ground-breaking pedal is operated to stably insert it into the ground. The lengths of the main support rod and the center support rod can be adjusted in multiple levels. After manually adjusting the inclination angle of the main support rod of the support frame, the angle of the center support rod is adjusted so that the angle forms a triangle, ensuring the stability of the entire support rod. By stepping on the anti-slip pedal with one foot, the gasoline engine is started and the rotating rod drives the drill bit to rotate for stable sampling operations on the slope surface. The pressurized water bottle supplies water to the rotating rod through the water pipe to cool it down. In the existing technology, small drilling devices can only drill perpendicular to the ground. However, due to the diversity of measured terrain and different measurement requirements, in some cases, drilling with a certain inclination angle is required, which cannot be met by the existing technology. content

[0026] The present invention will be further described below with reference to the accompanying drawings:

The rotation of the sprocket 202 drives the chain 203 to rotate. The chain 203 drives the connecting frame 104 to rise and fall, thereby realizing the lifting and lowering action of the drilling mechanism.

[0030] The drilling mechanism includes a drilling rig support frame 401 connected to the connecting frame 104 by screws, and an engine 402 is fixedly connected to the drilling rig support frame 401. The driving energy of the engine 402 is gasoline, which is a prior art and will not be described in detail.

Since the bracket 101, the bottom support frame 301, and the I-shaped telescopic structure form a triangle, changing the distance between the first T-frame 304 and the second T-frame 305 can change the angle between the bracket 101 and the bottom support frame 301, thereby realizing the function of controlling the drilling angle, the setting of the arc support 303 The support 101 can be limited so that it can only rotate within a limited angle to avoid damage to the device due to excessive rotation. In addition, the setting of the angle scale outside the arc support 303 can intuitively display the drilling angle. Before drilling, the staff screws the drill rod 405 into the output shaft 404, and then screws the drill bit 406 into the drill rod 405. Then, the lifting mechanism is used to make it pass through the limiting hole on the positioning plate 103, and the engine 402 is started. The engine 402 drives the output shaft 404 to rotate, and the output shaft 404 drives the drill rod 405 and the drill bit 406 to rotate to ensure smooth drilling. Then, the lifting component is operated. The staff manually holds the rotating handle 205 to drive the drive shaft 204 to rotate, and the drive shaft 204 drives the upper sprocket 202 to rotate. The rotation of the sprocket 202 drives the chain 203 to rotate, and the chain 203 drives the connecting frame 104 to rise and fall, thereby realizing the lifting action of the drilling mechanism, so that drilling work can be carried out.
