Description
Technical field
This utility model relates to engineering drilling, mine locating drilling tool accessory field, coal seam, is exactly specifically a kind of modified form borer.
Background technology
Fast development along with China's economic construction, energy demand is very big, coal resources are difficult to change as the main source of China's energy supply in the future for a long period of time, cause coal industry constantly towards mechanization, automation direction develops, mine roadway support anchor pole uses in a large number at underground coal mine, the safety in production in colliery is further ensured that, but in use drill bit does not has external protection device, and borer moves back brill when, easily drill bit is damaged, the service life causing drill bit is shorter, and work process occurs bit damage, also need to extract whole drill bit, again green bit is changed, so can affect work efficiency, increase running cost.
Summary of the invention
The purpose of this utility model is to provide a kind of modified form borer, and drill bit can be protected by this borer, the most still during moving back brill, solid drill is realized protection, extends the service life of borer, cost-effective.
The technical scheme in the invention for solving the technical problem is: a kind of modified form borer, including drill body, base and drill bit, the outside of described drill bit is provided with protective cover, described protective cover is hollow structure inside, protective cover piece cover is in the outside of drill bit, it is provided with fixed plate on described base, between described fixed plate and protective cover, stage clip is installed, described stage clip is uniformly stuck in the inboard groove of protective cover, the bottom of described protective cover is connected by screw with spacing ring, described spacing ring is that circular ferrule is sleeved on base, gap is left between lateral surface and the medial surface of protective cover of described drill bit, the upper end of described protective cover arranges circular open, drill bit can wear the opening of protective cover.
As optimization, the upper end of described protective cover is good to eat for horn opening, and the lower end of described horn opening is provided with circular convex joint.
As optimization, described fixed plate is welded with base.
As optimization, described protective cover is cylindrical shape cover body, and the length of protective cover is more than the length of drill bit.
The beneficial effects of the utility model are: compared with prior art, a kind of modified form borer of the present utility model, by designing protective cover in the outside of drill bit; drill bit can be played the effect of protection; effectively prevent the generation of the situation that drill bit is easily damaged after completing work, the protection to drill bit can be formed simultaneously in the course of the work, reduce slag with the contact of drill bit; improve work efficiency; and simple in construction, design ingenious, it is possible to popularization and application; improve the service life of drill bit, cost-effective.
Accompanying drawing explanation
Fig. 1 is this utility model overall construction drawing；
Wherein, 1 drill body, 2 bases, 3 drill bits, 4 protective covers, 5 horn openings, 6 circular convex joints, 7 stage clips, 8 spacing rings, 9 screws, 10 fixed plates.
Detailed description of the invention
As shown in Figure 1 in embodiment, a kind of modified form borer, including drill body 1, base 2 and drill bit 3, the outside of drill bit 3 is provided with protective cover 4, protective cover 4 is hollow structure inside, protective cover 4 piece cover is in the outside of drill bit 3, fixed plate 10 it is provided with on base 2, stage clip 7 is installed between fixed plate 10 and protective cover 4, stage clip 7 is uniformly stuck in the inboard groove of protective cover 4, the bottom of protective cover 4 is connected by screw 9 with spacing ring 8, spacing ring 8 is sleeved on base 2 for circular ferrule, gap is left between lateral surface and the medial surface of protective cover 4 of drill bit 3, the upper end of protective cover 4 arranges circular open, drill bit 3 can wear the opening of protective cover 4.
The upper end of protective cover 4 is good to eat for horn opening 5, and the lower end of horn opening 5 is provided with circular convex joint 6.
Fixed plate 10 is welded with base 2.
Protective cover 4 is cylindrical shape cover body, and the length of protective cover 4 is more than the length of drill bit 3.
A kind of modified form borer of the present utility model; by designing protective cover in the outside of drill bit, drill bit can be played the effect of protection, effectively prevent the generation of the situation that drill bit is easily damaged after completing work; the protection to drill bit can be formed in the course of the work simultaneously; reduce slag with the contact of drill bit, raising work efficiency, and simple in construction; design ingenious; can popularization and application, improve the service life of drill bit, cost-effective.
Above-mentioned detailed description of the invention is only concrete case of the present utility model; scope of patent protection of the present utility model includes but not limited to product form and the style of above-mentioned detailed description of the invention; any a kind of modified form borer meeting this utility model claims and any person of an ordinary skill in the technical field are suitably changed what it did or modify, and all should fall into scope of patent protection of the present utility model.
