Description
Technical Field
The utility model relates to the technical field of geological drilling bits, in particular to a single cone bit with easily replaced cutting teeth.
Background
The roller bit may be classified into a single roller bit, a tri-roller bit, and an assembled multi-roller bit according to the number of roller cones. Cutting materials can be classified into steel teeth (milling teeth) and insert roller bits. Besides the impact and crushing effects on stratum rock, the single-cone bit mainly relies on the shearing effects of teeth to crush the rock, and teeth at different positions on the cone perform shearing movements at the bottom of the well, so that the crushing of the bottom of the well rock is completed, and drilling operation is completed.
The rock breaking mode of shearing requires that the cutting teeth of the single-cone bit have stronger wear resistance, but the cutting teeth on the cone are generally milled teeth (milling bit) or embedded with hard alloy teeth (inserted bit), and the two processes can improve the strength of the cutting teeth of the cone, but simultaneously can lead to insufficient wear resistance of the teeth, so that the service life of the cutting teeth is shorter. After the cutting teeth are worn, the whole drill bit is abandoned, and when the drill bit is replaced, the whole drill bit is replaced for a long time due to the large mass of the drill bit, so that the drilling efficiency is reduced.
Disclosure of Invention
The utility model aims at: in order to solve the technical problems, the utility model provides the single-cone bit with the cutting teeth easy to replace, and the cutting teeth are designed to be of a detachable structure, so that the cutting teeth can be conveniently replaced by workers after being worn, and the service life of the bit is prolonged.
The utility model adopts the following technical scheme for realizing the purposes: the utility model provides a single cone bit of easy change cutting tooth, includes connecting axle, bit body and a plurality of tooth, a plurality of the outside of tooth is all seted up flutedly, a plurality of the inside all joint of recess has the cutting tooth, through connection has a plurality of bolt between cutting tooth and the corresponding recess.
In order to facilitate the installation of the cutting teeth by the bolts, the single-cone bit with the cutting teeth easy to replace is preferable, and a plurality of screw holes matched with the bolts are formed in the inner walls of the grooves.
In order to facilitate the production of the cutting teeth and simultaneously facilitate the adaptation of the cutting teeth to the inner wall of the groove, the single cone bit with the easily replaceable cutting teeth is preferable.
In order to maintain the strength of the teeth, it is preferable that the single cone bit as an easy-to-replace cutting tooth of the present utility model has a width of a and a width of b, and the length of a is not more than one half of the length of b.
In order to make the stress of the cutting teeth uniform, the single cone bit which is an easy-to-replace cutting tooth is preferable, and the cutting teeth are arranged around the connecting shaft as the shaft collar at equal intervals.
In order to improve the wear resistance of the cutting teeth, the single cone bit with the easily replaceable cutting teeth is preferably used, and the cutting teeth are made of high wear-resistant alloy or diamond.
The beneficial effects of the utility model are as follows: through designing the cutting tooth into detachable movable tooth, under the circumstances that the cutting tooth appears wearing and tearing, dismantle the back with the cutting tooth of wearing and tearing and change new cutting tooth on original connecting axle to reduce drilling cost, the life of extension former drill bit improves drilling efficiency simultaneously.
