Description

TECHNICAL FIELD

[0001] The application relates to the technical field of hydrogeological drilling devices, in particular to a hydrogeological drilling device. BACKGROUND

[0002] Hydrogeological drilling is an important means to obtain underground water resource information and study geological structure, and is widely used in underground water exploration, environmental monitoring, geological disaster prevention and other fields. In complex terrain areas such as deep mountains and old forests, due to the limitation of road conditions, large drilling equipment is difficult to enter, and small drilling machines are usually used for drilling operations. However, small drilling equipment faces many challenges during drilling, especially the problem of soil accumulation inside the borehole, which seriously affects the detection accuracy and efficiency. Therefore, developing a hydrogeological drilling device suitable for complex terrain and effectively solving the problem of soil accumulation has become an urgent need in the current hydrogeological exploration field.

[0003] At present, a small hydrogeological drilling device is usually composed of a drilling machine, a drill rod and a drill bit, and a borehole is formed underground through the rotation and impact of the drill bit. In order to detect underground geological information, ultrasonic detection or other detection equipment is usually used to collect data after the drilling is completed.

[0004] However, the traditional drilling device has obvious defects in actual use: during drilling, the soil inside the borehole is prone to falling into the bottom of the hole due to gravity, resulting in soil accumulation. This accumulation not only blocks the borehole and affects the entry of subsequent detection equipment, but also interferes with the accuracy of detection data and reduces the exploration effect. CONTENT OF THE INVENTION
