Description

Drilling equipment for rock

Technical Field

The invention belongs to the technical field of ore mining, and particularly relates to rock drilling equipment.

Background

Geology mainly comprises the difference of the earth's circle layers, physical properties, chemical properties, rock properties, mineral compositions, the output states and contact relations of rock stratums and rock masses, the occurrence conditions and distribution rules of mineral resources and the like. Ore refers to a collection of minerals from which useful components can be extracted or which themselves have some property that can be exploited. Ores can be divided into metallic and non-metallic minerals. The unit content of useful components in the ore is called ore grade, the precious metal ore such as gold, platinum and the like is expressed by gram or ton, and other ores are expressed by percentage. The value of the ore is measured by the ore grade, but the ore value is influenced by the composition of gangue and the amount of harmful impurities in the effective component ore. Generally need carry out trompil processing to the ore through rock drilling device when exploiting mine etc. to equipment such as stock, pipeline, cable are installed to the later stage. Rock drills are tools used to directly mine rock material and drill blastholes into rock formations to deposit explosives to blast the rock and thereby complete the mine of rock material or other rock work. Furthermore, rock drills may also be used as breakers for breaking hard layers such as concrete. The rock drill works according to the impact breaking principle, when working, the piston does high-frequency reciprocating motion and continuously impacts the drill rod tail, under the action of impact force, the drill rod head in the shape of a sharp wedge crushes and drills rock into a certain depth to form a dent, after the piston retracts, the drill rod rotates for a certain angle, the piston moves forwards, when impacting the drill rod tail again, a new dent is formed, a fan-shaped rock block between two dents is sheared by a horizontal component force generated on the drill rod head, the piston continuously impacts the drill rod tail, compressed air or pressure water is continuously input from a central hole of the drill rod, rock slag is discharged out of the hole, and a circular drill hole with a certain depth is formed.
