Small drilling device for hydraulic ring geological exploration

Abstract

The invention discloses a small drilling device for hydraulic ring geological exploration, which comprises a bottom plate, the upper surface of the bottom plate is fixedly connected with a coaming, the interior of the coaming is movably connected with a drilling device, the two sides of the drilling device are provided with fixing devices, the exterior of each fixing device is provided with an adjusting device, and the adjusting devices are movably connected with the coaming. The invention relates to the technical field of drilling. According to the small drilling device for hydraulic ring geological exploration, by arranging the drilling device, when equipment is used, a locking device fixes a drill bit to the top of the support, the drill bit conducts drilling operation on the ground under driving of an external motor, when the drill bit is installed, the length of a telescopic rod is changed according to the actual diameter of the drill bit, and a clamping plate clamps the drill bit; the ball rotates along with rotation of the drill bit, the screw rod is screwed into the telescopic rod, the clamping plate is fixed under the action of the clamping device and the screw rod, and the problem that the drilling diameter of traditional drilling equipment is fixed is solved.

Description

technical field [0001] The invention relates to the technical field of drilling, in particular to a small drilling device for geological exploration of hydraulic rings. Background technique [0002] When conducting hydrological, geological and environmental exploration, it is necessary to conduct geological drilling in designated areas, extract soil samples through drilling, and collect geological information at the same time to facilitate subsequent environmental improvement, oil and gas exploration and ground construction; [0003] Since the geological drilling equipment is mostly located in inaccessible and inconvenient areas, the traditional drilling equipment is limited by the volume and weight of the equipment, and it is inconvenient to disassemble, move and transport. When working on soft ground, the equipment is easy to sink and escape. Due to the fixed structure of the equipment, the hole diameter that can be drilled is limited. Contents of the invention [0004]...
