Adjustable drilling machine for mining

Abstract

The invention discloses an adjustable drilling machine for mining. The drilling machine comprises a lower bracket and an upper bracket. Horizontally symmetrical lifting devices are arranged on the upper side of the upper bracket. Each lifting device includes a supporting cylinder and a telescopic cylinder. Sliding chambers are formed in the walls of the supporting cylinders, the upper ends of thetelescopic cylinders are arranged in the sliding chambers, first motors are arranged at the upper ends of the interiors of the supporting cylinders, and threaded rods are arranged at the output ends of the first motors. Supporting columns are arranged in the telescopic cylinders, thread chambers are formed in the supporting columns, and the threaded rods are in threaded connection with the threaded chambers. Dust-proof covers are arranged on the outer sides of the supporting columns and the threaded rods, a lifting plate is arranged on the lifting devices, a rotating shaft is arranged in the middle of the lifting plate, and a drilling cylinder is arranged at the lower end of the rotating shaft. The drilling cylinder includes a digging cylinder, the upper end of the digging cylinder is fixedly connected with the lower end of the rotating shaft, a plurality of telescopic devices are disposed on the upper portion of the outer side of the digging cylinder, and digging pieces are arranged at the outer ends of the telescopic devices. The drilling machine is simple in structure and convenient to use and has a wide application range and long service life. The drilling diameter can be adjusted.

Description

technical field [0001] The invention relates to the technical field of mining devices, in particular to an adjustable drilling rig for mining. Background technique [0002] Mining is the technology and science of extracting mineral resources from within the Earth's crust and from the surface. Mining in a broad sense also includes the extraction of coal and oil. The mining industry is an important raw material industry, metal ore is the main raw material for the smelting industry, and non-metallic ore is an important chemical raw material and building material. Due to the complex occurrence conditions of metal deposits, the properties of ores and surrounding rocks are changing, and with the development of science and technology, new equipment and materials are constantly emerging, new processes are becoming more and more perfect, and some old ones are low in efficiency and labor-intensive. The existing mining methods have been correspondingly eliminated, and various mining ...

Problems solved by technology

Existing mine drilling machines use a hydraulic system to drive the drill bit up and down to realize mining, but generally speaking, the structure of the hydraulic system is responsible, and the maintenance cost is high. At the same time, the environment around the mine is dusty, especially during the mining process. The dust will cause the oil in the hydraulic system to be polluted, which will affect the performance of the drilling machine and greatly reduce the working efficiency of the drilling machine.
