Pneumatic rotary drilling percussion drill for super-hard rock

Abstract

The invention discloses a pneumatic rotary drilling percussion drill for super-hard rock. The pneumatic rotary drilling percussion drill comprises a bottom plate, wherein one side of the outer wall of the top of the bottom plate is fixedly connected with a supporting rod; the outer wall of one side of the supporting rod is fixedly connected with a main body frame; an adjusting groove is formed in the outer wall of one side of the main body frame; the inner wall of the top of the adjusting groove is fixedly connected with an air cylinder; one end of a piston rod of the air cylinder is fixedly connected with a sliding block; the sliding block is in sliding connection with the inner wall of the adjusting groove; adaptive grooves, which are distributed at equal distances, are formed in the inner walls of two sides of the adjusting groove; a cushion block is arranged on the outer wall of the bottom of the sliding block; adaptive blocks are arranged on the outer walls of two sides of the cushion block; and the outer walls of opposite sides of the adaptive blocks are fixedly connected with the same extrusion spring. According to the pneumatic rotary drilling percussion drill disclosed by the invention, when the sliding block and the cushion block descend, the two adaptive blocks connected with the extrusion spring continuously enter the different adaptive grooves to form a vibration effect with certain frequency, so that a drilling position is more efficiently impacted and rotary drilling is convenient to carry out.

Description

technical field [0001] The invention relates to the technical field of pneumatic drilling rigs, in particular to a pneumatic rotary drilling percussion drilling rig for superhard rock. 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. The ring and the ring seat are connected by a pin shaft, the ring seat and the hook rod are welded into one bod...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the existing superhard rock pneumatic rotary drilling percussion drilling rigs on the market have the following deficiencies in the process of use: when drilling with rotary drilling rigs, the existing drilling rigs have poor pneumatic impact effects, The digging process often requires greater energy consumption and poor practicability

In summary, most of the existing superhard rock pneumatic rotary percussion drilling rigs cannot meet the actual needs well
