Abstract
The utility model belongs to the field of drilling bits, particularly to a roof bolting bit, which is simple in structure, convenient, practical, high in water discharge, free of reducing and capable of protecting diamonds from cracking due to extrusion. The roof bolting bit comprises a bit body connected with a threaded rod, a left wing seat and a right wing seat opposite in direction are radially symmetrically disposed on the bit body, blades are respectively mounted on the left wing seat and the right wing seat, a face for the blade on the left wing seat and an inner upper vertical face of the right wing seat form a right-angled chip removal port, a face for the bade on the right wing seat and an inner upper vertical face of the left wing seat form another right-angled chip removal port, the left wing seat is connected with the right wing seat, and a water hole is arranged between the left wing seat and the right wing seat, and the diameter of the water hole is smaller than that of the threaded rod. The roof bolting bit has the advantages of simple structure, convenience, practicality, high water discharge, no reducing and capability of protecting the diamonds from cracking due to extrusion.
Description
Technical field
The utility model belongs to the drill bit field, be specifically related to a kind of simple in structure, convenient and practical, water yield is big, can undergauge and the protective money hard rock anchor bit that is not squeezed and bursts apart.
Technical background
Supporting is carried out by anchor pole mostly in the tunnel of mine, railway tunnel and water power department, thus bolthole to creep into workload big especially.In order to increase work efficiency, guarantee drilling quality, also more and more higher to the requirement of anchor bit.Now the drill bit that uses on the market is design patent number: 00319023.4 drill bit.This drill bit in use following point occurs through regular meeting: 1, the water hole diameter is little, and water yield is little, is unfavorable for arranging powder in the drilling process, and bit freezing, bury drills, paste bore and the burning of bits easily; 2, in drilling process, the both wings of drill bit are subjected to impacting and draw close to the centre easily, are undergauge thereby bit diameter is diminished, and the hole is beaten thinner and thinner; 3, in drilling process, can form a taper stone column in the middle of the both wings, stone column is along with drilling process deeply exerts pressure to both wings, thereby causes diamond to burst apart.
Summary of the invention
The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of simple in structure, convenient and practical, water yield is big, can undergauge and the protective money hard rock anchor bit that is not squeezed and bursts apart.
The purpose of this utility model be achieved in that comprise the bit body, the bit body that link to each other with threaded rod be provided with left wing's seat and right flank seat, described left wing seat and right flank seat distribute for radial symmetric on the bit body table top and face that direction opposite, described left wing seat and right flank seat are separately installed with blade, described left wing seat blade and right flank seat inboard on facade constitute a right angle move back the face of bits mouthful, described right flank seat blade and left wing seat inboard on facade constitute another right angle and move back and consider mouth to be worth doing, described left wing seat links to each other with the right flank seat; Be provided with the water hole between described left wing seat and the right flank seat, described water hole is less than the diameter of threaded rod.The inboard that the right angle of described right flank seat moves back bits mouthful is arc and intersects with the face lower end of left wing seat blade.The inboard that the right angle of described left wing seat moves back the bits mouth is an arc and crossing with the face lower end of right flank seat blade.
That the utility model device has is simple in structure, convenient and practical, water yield is big, can undergauge and the protective money hard rock advantage that is not squeezed and bursts apart.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is a vertical view of the present utility model.
The specific embodiment
As shown in Figure 1, 2, the utility model comprise the bit body 3, described left wing seat 1 and the right flank seat 2 that link to each other with threaded rod 4 distribute for radial symmetric on the bit body 3 and face that opposite, the described left wing of direction seat 1 and right flank seat 2 are separately installed with blade, described left wing seat blade and right flank seat inboard on facade constitute a right angle move back the face of bits mouthful, described right flank seat blade and left wing seat inboard on facade constitute another right angle and move back and consider mouth to be worth doing, described left wing seat 1 links to each other with right flank seat 2; Be provided with water hole 5 between described left wing seat 1 and the right flank seat 2, described water hole 5 is less than the diameter of threaded rod 4.The inboard that the right angle of described right flank seat moves back bits mouthful is arc and intersects with the face lower end of left wing seat blade.The inboard that the right angle of described left wing seat moves back the bits mouth is an arc and crossing with the face lower end of right flank seat blade.
Owing to the diameter of water hole 5 of the present utility model less than threaded rod 4, and between water hole 5 left wing's seats 1 and right flank seat 2; The diameter in water hole 5 is big, and water yield increases, and in the drilling process, row's powder is fast, thereby thoroughly solves bit freezing, bury drills, sticks with paste the phenomenon of the brill and the burning of bits; Because left wing's seat 1 links to each other with right flank seat 2, therefore in drilling process, both wings are subjected to the problem that can not there be undergauge in great extruding; In addition, link to each other with right flank seat 2 owing to left wing's seat 1 in the drilling process, so the taper stone column that forms between left wing's seat 1 and the right flank seat 2 pushes downwards; masterpiece is used in the junction; stone column breaks, thereby protection left and right sides both wings diamond can not be subjected to the extruding of taper stone column, causes bursting apart.As shown in Figure 1, the bottom of the utility model threaded rod 4 is the water inlet in water hole 5, and the top of bit body 3 is the delivery port in water hole 5.
Claims (3)
1. anchor bit, comprise that the bit body (3), described left wing seat (1) and the right flank seat (2) that link to each other with threaded rod (4) go up the last facade that right angle of last facade formation for radial symmetric distributes and opposite, the described left wing of direction seat (1) and right flank seat (2) are separately installed with blade, described left wing seat blade face and right flank seat inboard moves back the face of considering mouth, described right flank seat blade to be worth doing and left wing seat inboard at bit body (3) and constitute another right angle and move back and consider mouth to be worth doing, it is characterized in that: described left wing seat (1) links to each other with right flank seat (2); Be provided with water hole (5) between described left wing seat (1) and the right flank seat (2), described water hole (5) are less than the diameter of threaded rod (4).
2. anchor bit according to claim 1 is characterized in that: the inboard that the right angle of described right flank seat moves back bits mouthful is arc and intersects with the face lower end of left wing seat blade.
