Abstract
The utility model provides a multi-chamfered groove drill bit, in particular to the blasting construction of the deep hole smooth surface of stone heads, mainly comprising the drill bit and grooving tools. The grooving tool is welded with hard alloy blocks more than three, and round holes drilled can be provided with multiple grooves. During the blasting, the taper angle of the groove can generate concentrating stress with high degree for bursting along the direction of the groove; the bursting direction can be effectively controlled for making the bursting be shaped and smooth, and the rock is easy to break. When a vertical shaft or a tunnel is dug, the bursting is shaped and smooth; the wall rock is fixed and has high stability. When marbles and granites are mined, the utility model can implement the guided cutting and the mining with high finishing rate and large blocks.
Description
The utility model relates to a kind of drilling machine.A kind of polygonal gouge bit of more specifically saying so.Be applicable to the usefulness of the blast working boring of roadway blast working in the engineerings such as colliery, metallic ore, railway, water power, military affairs and other construction work or quarry.
The prior art of this technical field, can consult the open flume type drill bit of Patent Office of the People's Republic of China's patent No. for " 87211268 ", this drill bit can only be left two relative grooves in the hole, garden that gets out when boring, in the blast working of excavation, marble exploitation and other building engineering, the hole that gets out with this drill bit, explosion direction during explosion can not be controlled fully, especially when tunnelling, and the roadway forming irregularity, digging also can appear backbreaking and owing in section, influences safety and construction quality.
The purpose of this utility model designs a kind of polygonal gouge bit in order to overcome above-mentioned the deficiencies in the prior art part exactly, and it can get out the big gun hole that is no less than three grooves.Sharp corner generation stress highly at groove during explosion is concentrated, and makes it along the explosion of fluting direction, can control the explosion direction effectively, and it is regular that explosion is shaped.Can make catalase with comparalive ease, can also reduce drilling hole amount simultaneously and reduce explosive consumption.
The purpose of this utility model can realize by following manner:
A kind of screw connected polygonal gouge bit mainly is made up of drill bit, grooving tool, clamp nut, hexagonal steel, and drill bit is " one " font or " ten " font.Welding-on has carbide alloy.Afterbody band external screw thread and interior garden taper hole, the empty cover of grooving tool is installed on the drill bit, and the grooving tool welding-on has several hard alloy blocks, and fastening with clamp nut, hexagonal steel is inserted in the interior garden taper hole of drill bit.
The polygonal gouge bit of a kind of cone interconnection system mainly is made up of drill bit, grooving tool, connecting rod, hexagonal steel.Drill bit is " one " font or " ten " font, welding-on has carbide alloy.Garden taper hole in the afterbody band, the empty cover of grooving tool is installed on the connecting rod.Welding-on has hard alloy blocks on the grooving tool.Connecting rod one end has outer cone, is inserted in the interior garden taper hole of drill bit, and garden taper hole, hexagonal steel were inserted in the taper hole of the interior garden of connecting rod in the connecting rod other end had.
Description of drawings:
Accompanying drawing 1 is the polygonal gouge bit structure chart that is threaded of the present utility model.
Accompanying drawing 2 is A-A sectional drawings of Fig. 1.
Accompanying drawing 3 is another kind of grooving tool sectional views of the present utility model.
Accompanying drawing 4 is that cone of the present utility model connects polygonal gouge bit structure chart.
Accompanying drawing 5 is B-B sectional drawings of Fig. 4.
Accompanying drawing 6 is another kind of grooving tool sectional views of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in accompanying drawing 1,23: the polygonal gouge bit that is threaded mainly is made up of drill bit 1, grooving tool 2, clamp nut 3, hexagonal steel 4.Drill bit 1 is " one " font or " ten " font.Welding-on has carbide alloy, both sides are drilled with weep hole, afterbody band external screw thread and interior garden taper hole, grooving tool 2 are cylinder, have through hole along center line, make it can be sleeved on drill bit 1 afterbody, the column side face welding-on has hard alloy blocks, can have by different requirement welding-ons and be no less than three hard alloy blocks, grooving tool 2 empty covers are installed on the drill bit 1, use clamp nut 3 fastening then, and the end of hexagonal steel 4 band cones is inserted in the interior garden taper hole of drill bit 1.
With reference to accompanying drawing 4,5,6, shown in: the polygonal gouge bit that cone connects mainly is made up of drill bit 5, grooving tool 2, connecting rod 6, hexagonal steel 4.Drill bit 5 is " one " font or " ten " font, and welding-on has carbide alloy, and both sides are drilled with weep hole, garden taper hole in the afterbody band.Grooving tool 2 is Cylinder, has through hole along center line, and the column side face welding-on has hard alloy blocks, can have by difference requirement welding-on to be no less than three hard alloy blocks.Connecting rod 6 is a shape, has two Cylinders to be connected on it, has a small through hole along center line, and little garden styletable has cone, makes in its interior garden taper hole that can be inserted into drill bit 5, garden taper hole in big garden awl end has.Grooving tool 2 empty covers are installed on the little Cylinder of connecting rod 6, then connecting rod 6 are inserted in the interior garden taper hole of drill bit 5, and an end of the outer cone of hexagonal steel 4 bands is inserted in the interior garden taper hole of connecting rod 6.
During boring, drive drill bit 1 or drill bit 5 rotations by air rock drill by hexagonal steel 4, and impact, grooving tool 2 is owing to empty cover is installed on the outer garden of drill bit 1 or connecting rod 6, so grooving tool 2 does not rotate with drill bit 1 or drill bit 5, and the effect that only withstands shocks, the hard alloy blocks of welding-on on grooving tool 2 will be left groove in boring, the direction of the groove of being left and quantity, can control on demand, when beginning to hole, control with special-purpose wrench, take off special-purpose wrench later on when grooving tool 2 enters rock mass, grooving tool 2 can be left groove by required selected direction in the hole, garden.
The utlity model has following advantage: when the By Deep-hole Smooth Blasting construction of carrying out stone head, can make roadway forming regular, adjoining rock stability increases security. When Cut Blasting, easily realize. The deep trouth slotting improves the Cut Blasting effect. In the stone pit of opening of quarry marble, granite and other construction material stones, use of the present utility model, can realize directional cutting and high yield bulk the exploitation, can improve demolition effect, reduce cost.
