In in fixing axle, faulting of slab ends overlap joint is fixed one by one for the outer blade and internal layer blade.
Internal layer strengthening steel slab is welded on the internal layer blade, the internal layer strengthening steel slab is welded in adjacent inner layer leaf piecewise
Between piece, circular internal layer ruggedized construction is enclosed；Outer layer strengthening steel slab is welded on the outer blade, the outer layer is reinforced
Steel plate is welded in piecewise between adjacent outward layer blade, encloses the outer layer ruggedized construction of polygon.
The lower end of the internal layer blade, the lower end of outer blade and outer end are welded with hard-metal insert.
The hard-metal insert is the alloy steel nail that interval is welded and fixed, and alloy steel nail length is 1cm, adjacent alloys steel nail
Between spacing distance be 2cm.
The drilling rod interconnecting piece is the concave mantle fiber that fixing axle upper end is arranged in, and the drill bit interconnecting piece is to be arranged in fixation
The convex mantle fiber of axis lower end.
The drilling rod interconnecting piece is connected with short circuit connecting rod, and the upper end for being shorted connecting rod has concave mantle fiber.
The quantity of the internal layer blade and outer blade is 4-8 piece.
Using being welded with a thickness of the steel plate faulting of slab ends of 1cm, welding faulting of slab ends overlap joint is grown for the internal layer blade and outer blade
Degree is 1cm, and internal layer blade is higher by 1cm than outer blade.
The fixing axle is hollow shaft.
The double-deck reaming blade is installed, reaming blade outermost layer blade determines that boring aperture is big in the fixing axle of the utility model
Small, inside and outside two layers of reaming blade is welded and fixed using steel plate.By fixing axle one end jointed rod of the utility model, one end connection
Drill bit is used cooperatively with drill bit of drilling machine, can drill out required aperture.The utility model can need to can be processed into difference according to operation
Size, processing and fabricating is simple, and operation effectiveness is good, can save equipment acquisition cost and time cost.
Detailed description of the invention
Fig. 1 is the sectional view of the utility model；
Fig. 2 is the A-A cross-section diagram of the utility model；
In figure: 1- fixing axle, 2- internal layer blade, 3- outer blade, 4- internal layer ruggedized construction, 5- outer layer ruggedized construction, 6-
Alloy steel nail, 7- are shorted connecting rod.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing, but the utility model is not limited to specific embodiment.
Embodiment
Rock reamer as shown in Figure 1 and Figure 2 includes drilling fixing axle 1, internal layer blade 2, outer blade 3, internal layer reinforcing
Structure 4, outer layer ruggedized construction 5, alloy steel nail 6 and short circuit connecting rod 7.
Fixing axle 1 is 40cm long, diameter 50mm, upper end have concave mantle fiber, can be directly connected to drilling rod, concave mantle fiber with
The mating mantle fiber of drilling rod is tightened, and can also be tightened with the mating mantle fiber of connecting rod 7 is shorted, then by being shorted in connecting rod 7
The concave mantle fiber jointed rod in portion.1 lower end of fixing axle has convex mantle fiber, can be tightened with mating drill bit of drilling machine mantle fiber.Gu
Dead axle 1 uses hollow shaft, is applicable to injection drill.
Rock reamer is made of 12 blades altogether, and internal layer blade 2 and outer blade 3 are respectively 6,2 edge of internal layer blade
1 circumferencial direction interval of fixing axle is fixed in fixing axle 1, and internal layer blade 2 and outer blade 3 are welded using the steel plate faulting of slab ends of 1cm thickness
It connects, welds faulting of slab ends lap of splice 1cm, internal layer blade 2 is higher by 1cm than outer blade 3, in 2 lower end of internal layer blade, outer layer leaf
