Abstract
Description
Technical Field
[0001] This invention belongs to the field of drilling equipment technology, specifically a drilling equipment for geotechnical engineering exploration. Background Technology
[0002] In geotechnical engineering investigations, drilling is a crucial method for obtaining the physical and mechanical parameters of underground soil and rock layers, determining the geological structure, and assessing groundwater distribution. Traditional drilling equipment typically uses mechanical or hydraulic drives to rotate the drill bit and penetrate the strata. However, during actual construction, especially when drilling in dry or severely weathered soil and rock layers, large amounts of dust are easily generated. This dust not only severely pollutes the construction site environment but can also harm the respiratory system of operators, and long-term exposure can even lead to occupational diseases such as pneumoconiosis. Furthermore, with increasingly stringent national environmental protection requirements for construction, dust control has become a critical issue that must be addressed on geotechnical engineering sites.
[0003] On the other hand, the drilling process generates strong vibrations and noise due to the intense friction and impact between the drill bit and the rock strata. Existing equipment generally lacks effective vibration and noise reduction structures, resulting in poor equipment stability, easy wear of parts, and noise pollution to the surrounding environment, affecting construction safety and efficiency. Therefore, there is an urgent need to develop a new type of geotechnical engineering exploration drilling equipment that integrates efficient dust reduction, stable drilling, and good vibration reduction performance to meet the dual needs of modern green construction and safe production.

The sliding plate 32 is rotatably connected to the slide rod 27.
[0030] In this embodiment, specifically: the support rod on the device bracket 1 is provided with a first slide groove 34, and the first slide groove 34 limits and guides the movement of the slide plate 32 through the internal sliding slider 35, while the slide plate 32 is provided with a through hole 33 for penetrating mist water.

[0036] Working principle or structural principle: First, the equipment is moved to the location where the rock strata need to be drilled. Then, motor 21 is started. The output end of motor 21 drives the drive shaft 22 to rotate. The rotation of drive shaft 22 drives the first pulley 23 to rotate. The rotation of the first pulley 23 drives the transmission belt 24 to rotate. The rotation of transmission belt 24 drives the second pulley 25 to rotate. The rotation of the second pulley 25 drives the hollow rod 26 to rotate. The rotation of hollow rod 26 drives the slide rod 27 to rotate. The rotation of slide rod 27 drives the auger drill bit 28 to rotate. At the same time, hydraulic rod 31 is started. The extension end of hydraulic rod 31 drives slide plate 32 to move downward. The downward movement of slide plate 32 drives slide rod 27 to move downward. The downward movement of slide rod 27 drives the auger drill bit 28 to rotate downward to drill into the rock strata. At the same time, water pump 211 is started, and water pump 211 pumps water... Water inside the tank 210 is drawn into the outlet pipe 212 and finally reaches the hollow rod 26. At the same time, the rotation of the hollow rod 26 can drive the spray head 29 to rotate, and the rotation of the spray head 29 can spray the water inside the hollow rod 26 to form a mist. Spraying atomized water on the drilling area can suppress dust diffusion in real time during drilling, significantly reducing dust pollution at the construction site. When drilling generates vibration, the connecting block 62 slides in the second slide groove 5, compressing or stretching the return spring 64. At the same time, the damping rod 61 absorbs the impact energy and further drives the connecting rod 63 to be hinged at both ends to the connecting block 62 and the bottom of the equipment support 1, forming a four-bar buffer structure, which disperses and dissipates vibration, thereby effectively absorbing the vibration impact generated during drilling, reducing drilling noise, and reducing noise pollution in the environment.
