Geological drilling device for highway investigation

Abstract

The invention provides a geological drilling device for road investigation, which comprises a vehicle body base, a weeding mechanism, a drilling box, a motor loading plate, a sampling box, a fixer and a second motor, the weeding mechanism is mounted at the front end of the vehicle body base, the drilling box is mounted in the middle of the vehicle body base, and the weeding mechanism comprises a screw rod, a cutter head, a second motor and a chain. The output end of the second motor drives a chain, the chain drives the lead screw, a motor loading plate is arranged above the drilling box, a first motor is fixed to the top of the motor loading plate, the output end of the first motor drives a drill rod, and the outer side of the drill rod is sleeved with a conveying pipe. A spiral conveying blade is arranged on the portion, located in the conveying pipe, of the drill rod, a drill bit is arranged at the bottom end of the drill rod, a reaming cutter is arranged on the drill rod and located between the spiral conveying blade and the drill bit, the hydraulic supporting rod is in driving connection with the motor loading plate, and a plurality of fixers are in threaded connection with the vehicle body base. The geological drilling device is convenient and fast, and the exploration efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a geological drilling device for highway exploration. Background technique [0002] Drilling is an important means to obtain accurate geological data under the surface in engineering geological survey. Drilling during surveying should be carried out on the basis of surveying, mapping and geophysical prospecting. Exploration lines and networks should be arranged purposefully and in a planned manner according to survey stage, project scale and complexity of geological conditions. Carry out the principle of sparse first and then dense. In the process of highway survey, the required drilling device obtains the geological data under the surface, but for the general drilling device, it is not easy to move. When the mountain road is surveyed, the vehicle cannot pass, and multiple workers are required to lift it to the required location. Point, the process is time-consum...

Problems solved by technology

In the process of highway survey, the required drilling device obtains the geological data under the surface, but for the general drilling device, it is not easy to move. When the mountain road is surveyed, the vehicle cannot pass, and multiple workers are required to lift it to the required location. point, the process is time-consuming and labor-intensive, and the mountain road is full of thorns, which increases the difficulty of the staff's work and is not convenient for road survey
