Description
Technical Field
The utility model relates to a diamond bit technical field, concretely relates to diamond bit with chip breaking and chip removal function.
Background
Diamond drill bits are a type of drilling tool used for earth boring, and have found widespread use in earth boring engineering in recent years. The diamond bit is composed of a bit body, a diamond bit head and the like, and the diamond bit crushes rock by pressing and shearing rock layers generated by contact of cutting teeth of the diamond bit and the rock layers. In the drilling construction in the environment of large-caliber gravel and bedrock, because broken rock particles are large and difficult to remove chips, the inner cavity of a drill bit matrix is easily blocked, and the normal work of a diamond drill bit is influenced, so that the construction efficiency is influenced, and the construction cost is increased. Therefore, the construction is often slow in drilling speed and cannot meet the requirement of the overall construction efficiency of the project.

A gap is arranged between the first boss cutter head and the second boss cutter head.
The first boss cutter head and the second boss cutter head are conical tables, and the angle of the upper base angle of the trapezoid on the central section of each conical table ranges from 95 degrees to 135 degrees.
The height of the first boss cutter head is larger than one third of the depth of the inner cavity and smaller than one half of the depth of the inner cavity.
The bottom of the first boss cutter head is directly smaller than one half of the inner diameter of the inner cavity.
The second boss cutter head is welded on the wall of the inner cavity.
The bottom surface of the inner cavity is provided with a plurality of chip removal holes with the diameter of 3-5mm, and the chip removal holes are uniformly distributed.
The diamond abrasive particles are fixedly connected to the diamond tool bit, the first boss tool bit or the second boss tool bit through electroplating or brazing.
The grain diameter of the diamond abrasive grains is 1.5-2.0 mm.
The utility model adopts the above technical scheme, through set up first boss tool bit in drill bit base member inner chamber bottom center, the inner chamber wall sets up second boss tool bit more than two, and set up the diamond grit at first boss tool bit and second boss tool bit terminal surface and side, further become tiny particle or likepowder granule at the broken large granule rock in inner chamber, just so can discharge from several chip removal hole, drill bit base member inner chamber just can not block up, diamond bit can the continuity of operation, consequently, technical scheme can improve the efficiency of construction more than adopting, construction cost is reduced.
