The dust prevention type mining drilling machine comprises a lower support and an upper support, a plurality of damping devicesare arranged between the lower support and the upper support, supporting columns are left-right symmetrically arranged on the upper side of the upper support, a lifting cavity is formed in the inner side of each supporting column, a first motor is arranged at the upper end of each supporting column, a threaded rod is arranged at the output end of each first motor, a lifting seat is arranged on each threaded rod, a lifting plate is arranged between the two lifting seats, a rotary shaft is arranged in the middle of the lifting plate, a second motor is arranged on the upper side of the lifting plate, a driving wheel is arranged at the output end of the second motor, a driven wheel is arranged at the upper end of the rotary shaft, a drilling cylinder is arranged at the lower end of the rotaryshaft, the drilling cylinder comprises an excavation cylinder, the upper end of the excavation cylinder is fixedly connected with the lower end of the rotary shaft, a plurality of telescopic devices are arranged on the upper portion of the outer side of the excavation cylinder, and excavation sheets are arranged at the outer ends of the telescopic devices. The dust prevention type mining drillingmachine is simple in structure and convenient to use, can adjust the diameter of drilling, and is wide in application range and long in service life.

Description

technical field [0001] The invention relates to the technical field of mining devices, in particular to a dust-proof mining drilling rig. 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 metho...

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.
