Drilling machine for exploration engineering

Abstract

The invention belongs to the technical field of drilling machines, and particularly relates to a drilling machine for exploration engineering. The drilling machine comprises a rack, a cutterhead and alocking module; two electric push rods are mounted at the top of the inner side of the rack, and the bottom ends of the two electric push rods are fixedly connected with a motor connecting seat; a first motor is mounted at the bottom of the motor connecting seat and is in transmission connection with the cutterhead through a rotary shaft; the inner side of the cutterhead is rotationally connectedwith two lead screws which are arranged up and down in a cross-shaped mode; a second motor is mounted on the inner side of the cutterhead, and four sets of sliding grooves are formed in the positions, corresponding to the two lead screws, on the cutterhead; the second motor is in transmission connection with the corresponding lead screw; the two ends of the lead screws are provided with connecting blocks correspondingly; the lead screws are used for driving the connecting blocks to move, and an arc-shaped elastic plate is fixedly connected between any two adjacent sets of connecting blocks; and sliding blocks are arranged in the sliding grooves, and the bottom ends of the sliding blocks are fixedly connected with a cutter. Drill holes with different sizes can be drilled, the drilling efficiency is improved effectively, water mist dust removal is utilized, and thus the dust removal efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of drilling rigs, in particular to a drilling rig for exploration engineering. Background technique [0002] A drilling rig is a complex set of machines, which consists of machines, units and mechanisms. A drilling rig is a mechanical device that drives a drilling tool to drill underground to obtain physical geological data during exploration or mineral resource development (including solid ore, liquid ore, gas ore, etc.). Also known as drilling machine. The main function is to drive the drilling tool to break the rock at the bottom of the hole, and to lower or lift the drilling tool in the hole. It can be used to drill cores, ore cores, cuttings, gaseous samples, liquid samples, etc., to ascertain the conditions of underground geology and mineral resources.

Problems solved by technology

[0003] However, when the existing drilling rigs are drilling holes, the matching drill bits need to be replaced for drilling holes with different diameters, which leads to a reduction in work efficiency during drilling, and produces a large amount of dust in the drilling process, which spreads in the air. If inhaled by workers, it will easily cause occupational diseases in the long run and endanger the health of workers.
