During due to borehole pressure it is very big, the muddy water in drilling rod can spray from drilling rod upper end, influence operative.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of structure design simply, with preventing back compared with high practicability
Rhinestone head device.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of anti-backwater drill bit device, including：Drill bit (the brill wing), drill body, guard ring, lever and floater shot, the drill body is
Hollow-core construction, the drill body lower end is fixedly connected with drill bit, and drill body upper end inwall is matched provided with joint silk for same drilling rod, described
Guard ring is arranged on the edge of drill bit, and the lever is arranged in drill body, and the floater shot is set in the cavity of drill body, and positioned at shelves
Between bar and joint silk, the lower section of joint silk is provided with block edge, water stream channel is formed in the middle of block edge；During normal drilling well, by
Flowed from top to bottom in water, floater shot is located at lever；When needing increase drilling rod, it is necessary to which the drilling rod of the top and rig are torn open
Lay down, now because inner pressure inside pipe is released, while the water in drilling rod up sprays drive floater shot move upwards by
Water stream channel is blocked so that drilling rod topmost sprays without muddy water.
It is preferred that, the lever is connected in drill body using dismountable mode, such as grafting, is spirally connected, by lever
Dismounting can change floater shot.
It is preferred that, the block edge of the joint silk bottom is designed as arcuate structure so that floater shot can be good at current
Passage is sealed up.
It is preferred that, described floater shot is made up of nonmetallic materials, such as plastics, rubber, timber.
It is preferred that, the lever is arranged at intervals, and gap is left between lever and lever, it is ensured that water being capable of proper flow.
It is preferred that, the drill bit is three wings or four wing bit.
It is preferred that, the floater shot is hollow metal sphere.
The beneficial effects of the invention are as follows：The present invention is simple in construction, novel in design, by doing simple modifications to drill bit, increase
One ball float, solves the problems, such as drilling rod backwater, improves the efficiency of drilling rod assembling, it is ensured that safety in production.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is structure top view of the present invention.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
Embodiment 1
As shown in Figure 1 and Figure 2, a kind of anti-backwater drill bit device, including：Drill bit 3, drill body 5, guard ring 4, lever 6 and floater shot
1, drill body 5 is hollow-core construction, and the lower end of drill body 5 is fixedly connected with drill bit 3, and the upper end inwall of drill body 5 is provided with joint silk 2, for same
Drilling rod is matched, and guard ring 4 is arranged on the edge of drill bit 3, and lever 6 is arranged in drill body 5, and floater shot 1 is set in the cavity of drill body 5,
And between lever 6 and joint silk 2, the lower section of joint silk 2 is provided with block edge, water stream channel is formed in the middle of block edge；Shelves
Bar 6 is connected in drill body 5 using dismountable mode, is such as spirally connected, floater shot 1 can be changed by the dismounting to lever 6.Lever
6 are arranged at intervals, and leave gap between lever 6 and lever 6, it is ensured that water being capable of proper flow.The block edge of 2 bottoms of joint silk is designed as
Arcuate structure so that floater shot 1 can be good at sealing up water stream channel, floater shot 1 is made up of nonmetallic materials, such as moulds
Material.
During normal drilling well, because water flows from top to bottom, floater shot 1 is located at lever 6；When needing increase drilling rod, need
The drilling rod of the top and rig down are fallen, now because inner pressure inside pipe is released, what the water in drilling rod up sprayed
Driving floater shot 1 simultaneously, water stream channel is blocked in motion upwards so that drilling rod topmost sprays without muddy water.
Embodiment 2
As shown in Figure 1 and Figure 2, a kind of anti-backwater drill bit device, including：Drill bit 3, drill body 5, guard ring 4, lever 6 and floater shot
