[0002] The drilling wheel drill bit is also called the roller drill bit. The roller drill bit is the most widely used drilling bit. When the roller drill bit is working, the cutting teeth alternately contact the bottom of the well, the rock breaking torque is small, the contact area between the cutting teeth and the bottom of the well is small, the specific pressure is high, and it is easy to penetrate into the formation; the roller drill bit can adapt to a variety of formations from soft to hard.

[0003] A grooved gear drill bit with announcement number CN215408478U includes a matrix, toothed structures are evenly distributed on the end of the matrix, water outlets are provided between adjacent toothed structures, multiple teeth are arranged on each toothed structure, and grooves are provided on the end face of each tooth. The structure design of the utility model is reasonable and ingenious. Since the end face of the matrix is ​​a toothed structure with grooves, the contact area between the end face and the rock is small during operation, and the local pressure increases under the same drilling pressure, so that the matrix can quickly cut with the rock during operation, and due to the presence of the grooves and the increase of the water outlets, the stability during operation is further improved, the flushing speed of the rock powder is also increased, and the cutting efficiency of the drill bit and the work are greatly improved.

[0004] In the above technical solution, since the end face of the matrix is ​​a toothed structure with grooves, the contact area between the end face and the rock is small during operation, and the local pressure increases under the same drilling pressure, so that the matrix can quickly cut out the rock during operation. However, during long-term crushing and cutting, the toothed structure will be worn. When replacing the toothed structure, the matrix needs to be replaced as a whole, thereby increasing the economic loss of the user. For this reason, we provide an alloy wheel drill bit for drilling with an auxiliary load-bearing function. Utility Model Content
