Background technique
Currently, when coal mine is drilled, it is smaller that the drill bit of use forms boring aperture mostly, needs to carry out reaming again,
Especially when carrying out gas drainage, discharging water, existing reaming is all to be cut again using bottom outlet as pilot hole so that hole
Diameter becomes larger, and cutting output is limited, cannot form large area cutting reaming, for what is be relatively large in diameter, needs to repeat operation ability to this
It completes, is unable to one-stop operation and carries out reaming, and the rock slag cut cannot exclude in time, deslagging space is limited, existing also to match
Hole for water spraying carries out deslagging on bench drill head, it is easy to and rock slag is mixed into mud, influences chip removal, low efficiency, reaming covering surface is small, edge
Radial feeds are small.
Summary of the invention
In order to improve above situation, the utility model coal mine drilling expanding structure provides one kind and passes through spiral plate for rock slag
Discharge in time, and by being cut while circumferential and radial direction, improve the expanding structure of reaming efficiency.Structure is simple, convenient and practical.
The utility model coal mine drilling expanding structure is achieved in that the utility model coal mine drilling expanding structure by even
Female connector, driving cog, pernetti, cutting head, cutting blade, bearing, slag discharge plate, guide head, shaft, bearing shell, drive rod and bevel gear set
At, connector sleeve is placed on shaft one end, and driving cog is equipped on described connector sleeve one end, and guide head is placed on the shaft other end,
The guide head is cone-shaped structure, and slag discharge plate is placed on the outside of guide head, and the slag discharge plate is spiral plate, is passed through in the middle part of pernetti
Bearing is placed in shaft, and the pernetti angularly sets that there are four L between connector sleeve and guide head on the outside of the pernetti
Template, drive rod run through L-type plate, bearing shell are equipped between the drive rod and L-type plate, and bevel gear is placed on drive rod one end, and
It is meshed with driving cog, cutting head is placed on the drive rod other end, and multiple groups cutting blade is equidistantly placed on the outside of cutting head, and is divided in a ring
Cloth, every group of cutting blade are made of at least five cutting blades, and the cutting blade is trapezium structure, and upper bottom is inclined-plane.
In use, connector sleeve is connected with external motive device first, will be oriented to when carrying out reaming to coal mine drilling
Head is placed in drilling, and external motive device drives connector sleeve rotation, and the utility model of gradually promoting comprehensively into drilling, is led
Direction of propulsion is oriented to head, the driving cog on connector sleeve follows connector sleeve to rotate, and connector sleeve drives shaft rotation,
Shaft drives guide head rotation, and pernetti is driven to rotate, and pernetti drives four cutting heads to carry out circumferential turn in drilling
It is dynamic, and then circumferential cutting is carried out to drilling, meanwhile, four bevel gears rotate respectively under driving cog drive, four bevel gears point
Connected drive rod rotation is not driven, and four drive rods drive connected cutting head to rotate respectively, and cutting head is in drilling inner circumferential
Rotation is carried out while rotation, and then cutting head drives the cutting blade in outside to carry out radial cutting to drilling, guide head drives deslagging
Plate rotates, and rock slag caused by cutting carries out spiral along slag discharge plate and moves, and then rock slag is discharged in time out of drilling, Jin Ertong
The reaming that cutting carries out large area to drilling end face while crossing circumferential and radial is cut, and is improved reaming efficiency, is reached to coal mine
Drilling carries out the purpose of reaming.
Beneficial effect.
One, structure is simple, convenient and practical.
Two, cheap, it is easy to spread.
Three, the reaming efficiency to coal mine drilling can be effectively improved.
Detailed description of the invention
Fig. 1 is the three-dimensional structure diagram of the utility model coal mine drilling expanding structure.
