Abstract
The utility model relates to a kind of anti-silt plug-hole geological drill bit, comprise jointed rod and bit body, jointed rod and bit body are threaded, bit body is provided with blade, inlet opening in the processing of jointed rod center, bit body is processed with weep hole, and jointed rod and bit body junction are provided with spring and steel ball, spring-compressed is between steel ball and bit body, and the diameter of steel ball is greater than the diameter of inlet opening.The utility model arranges spring and steel ball between jointed rod and bit body, the inlet opening of jointed rod is close under the action of the spring by steel ball, which results in the water flowed out from inlet opening and will have certain pressure to overcome spring to steel ball pressure, press water flows out from weep hole, larger to the silt underwashing force rate at weep hole place, prevent silt in the delay of weep hole, when stopping water inlet, under the action of the spring, steel ball can block inlet opening timely, prevents and flows to weep hole even in inlet opening.
Description
Technical field
The utility model relates to a kind of geological drill bit, specifically a kind of anti-silt plug-hole geological drill bit.
Background technology
At present, geological drill bit operationally, utilizes the centre bore water filling of drilling rod, can cool drill bit so on the one hand, be used on the other hand washing away and bore the chip of falling, sometimes should be the reason of geology, silt is many, and silt becomes mud after washing away through flowing water, not easily gone out by flowing water, the weep hole of geological drill bit even can be caused to block, and then damage drill bit, affect work.
Utility model content
The technical problems to be solved in the utility model is: silt can cause the weep hole of geological drill bit to block, and for solving the problem, provides a kind of anti-silt plug-hole address drill bit.
The purpose of this utility model realizes in the following manner:
Anti-silt plug-hole geological drill bit, comprise jointed rod and bit body, jointed rod and bit body are threaded, bit body is provided with blade, and inlet opening in the processing of jointed rod center, bit body is processed with weep hole, jointed rod and bit body junction are provided with spring and steel ball, jointed rod inlet opening is close to by steel ball, and spring-compressed is between steel ball and bit body, and the diameter of steel ball is greater than the diameter of inlet opening.
Described spring is cone spring.
Relative to prior art, the utility model arranges spring and steel ball between jointed rod and bit body, the inlet opening of jointed rod is close under the action of the spring by steel ball, which results in the water flowed out from inlet opening and will have certain pressure to overcome spring to steel ball pressure, press water flows out from weep hole, larger to the silt underwashing force rate at weep hole place, prevent silt in the delay of weep hole, when stopping water inlet, under the action of the spring, steel ball can block inlet opening timely, prevents and flows to weep hole even in inlet opening.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein, 1 is jointed rod; 2 is bit bodys; 3 is weep holes; 4 is blades; 5 is springs; 6 is steel balls; 7 is inlet openings.
Detailed description of the invention
As shown in Figure 1, anti-silt plug-hole geological drill bit, comprise jointed rod 1 and bit body 2, jointed rod 1 and bit body 2 are threaded, and bit body 2 are provided with blade 4, inlet opening 7 in the processing of jointed rod 1 center, bit body 2 is processed with weep hole 3, jointed rod 1 and bit body 2 junction are provided with spring 5 and steel ball 6, and jointed rod inlet opening 7 is close to by steel ball 6, spring 5 is compressed between steel ball 6 and bit body 2, and the diameter of steel ball 6 is greater than the diameter of inlet opening 7.Described spring 5 is cone spring.The larger diameter end of cone spring is close on bit body, and smaller diameter end contacts with steel ball, like this can the position of better locking ball 6, ensure that the reliability of steel ball 6 plug-hole.
When the utility model does not enter press water in the inlet opening 7 of jointed rod 1, cut off between inlet opening 7 and weep hole 3, there will not be the phenomenon of silt plug-hole, when adding press water in inlet opening 7, the pressure of water inlet is greater than the elastic force of spring 5, and inlet opening 7 just can be made to be communicated with weep hole 3, the water flowed out from weep hole 3 like this has certain pressure, the scouring force of water to silt flowed out is larger, makes weep hole 3 does not adhere to silt, and the phenomenon avoiding silt plug-hole occurs.
Claims (2)
1. anti-silt plug-hole geological drill bit, comprise jointed rod and bit body, jointed rod and bit body are threaded, bit body is provided with blade, and inlet opening in the processing of jointed rod center, bit body is processed with weep hole, it is characterized in that: jointed rod and bit body junction are provided with spring and steel ball, jointed rod inlet opening is close to by steel ball, and spring-compressed is between steel ball and bit body, and the diameter of steel ball is greater than the diameter of inlet opening.
2. anti-silt plug-hole geological drill bit according to claim 1, is characterized in that: described spring is cone spring.
