By a multi-bit design, working area is increased, and working efficiency is improved; by a spring design, abrasion of the rotary bit is reduced, and resources are saved; and by the drainage modules, the quantity of dust generated in a mining process is reduced.
Description
Technical field
The present invention relates to winning equipment field, be specially rotary drilling-head.
Background technology
Mining is in the earth's crust and the technology of earth's surface exploit mineral resources and science, and the mining of broad sense also comprises the exploitation of coal and oil.Mining industry is a kind of important primary industry, and metallic ore is the primary raw material of metallurgy industry, and non-metallic ore is important industrial chemicals and constructional materials.Mining activity grows up along with moving ahead of human civilization, counts and also has the history of thousands of years.
Hominid can gather building stones, is polished into the tool of production, and gathering potter's clay for potting, is exactly the rudiment of digging up mine the earliest.The mining of ancient Chinese is with a long history, being unearthed from Daye, hubei Province Tonglushan Mine ancient mine remains has for the copper of digging, loading, lifting, draining, illumination etc., iron, wood, bamboo, the thing such as the multiple tool of production made of stones and pottery, copper ingot, copper ordnance, confirm that the The Spring and Autumn Period has employed vertical, inclined shaft, gallery combined development, begun to take shape Underground Mining System.To Western Han Dynastry period, mining system is quite perfect.Now in Hebei, Shandong, the ground such as Hubei the ore deposit such as iron, copper, coal, gold dust all started exploitation.The state of Qin in latter stage of Warring states another name for Sichuan Province procurator Li Bing digs salt well within the border in Shuangliu County, modern Sichuan Province, draws halogen and gets salt by evaporation of sea-water, boil the salt off the water.The production of iron, copper, tin, lead, silver, gold, mercury, zinc is mainly contained before the Ming Dynasty.
At the beginning of the 17th century, the black powder that China imports into by European be used for mining, with driling explosion fall ore deposit replace hand digging, this be mining technique development a milestone.19 beginnings of the century in the end of the century 20, in succession invent mining explosive, detonator, detonating fuse and rock drilling equipment, defined blasting technique in modern age; The use of the equipment such as motor machine shovel, electric locomotive and electric power lifting, communication, draining, defines and loaded and transported technology modern age.20 th Century start, and mining technique develops rapidly, have occurred ammonium nitrate explosive, employ underground deep hole blasting technology, and various mining equiment constantly improves and maximizes, and progressively defines the mechanized mining technique being applicable to different mineral deposits condition.Propose the scientific method of mining design, the evaluation of deposits and mine project management, mining is developed to engineering science from skill.After the 1950's, owing to employing the novel device such as down-the-hole drill, rotary drill, voluntarily jumbo, extractive equipment realizes maximization, transported lifts automation, has occurred unmanned engine.Electronic computer technology is used for mine management, planning and designing and scientific algorithm, starts by systematic science research mining problem, the system that has been born mining engineering.Mining production starts to set up automatic control system, utilizes modern testing equipment, measuring technology and electronic computer, predicts and resolve some practical problem.Therefore mining engineering subject is formally proposed and is obtained generally acknowledged.
Along with the development of science and technology, mining also develops into mechanization running from original manual operation.In winning equipment, drill bit is very important assembly, and drill bit is the cutter on brill, drilling machine, rig.Hole can be caused on workpiece or rock.Existing drill bit mainly comprises fluted drill, chit drill, depth drill, reamer, centre drill, core drill etc.
Although the kind of drill bit is a lot, but the actual conditions in mining process are also diversified, existing drill bit can not meet diversified demand in mining activity, and the equipment replacement drill bit that stops during bit damage in addition also reduces the efficiency of mining to a certain extent.
