Description
Предлагаемое долото имеет целью бурение в породах перемежающейс твердости.The proposed bit aims to drill in rocks of intermittent hardness.
На схематическом чертеже фиг. 1 изображает вид долота сбоку; фиг. 2- вид снизу.In the schematic drawing of FIG. 1 shows a bit view from the side; FIG. 2 - bottom view.
Предлагаемое долото представл ет собой болванку, с торца которой сн ты два неполных сектора. Торцева часть А долота снабжена насечкой, аналогичной имеющейс в шарожечных долотах. Кроме того, оно снабжено двум лезви ми В, направленными в сторону вращени .The proposed bit is a blank, from the end of which two incomplete sectors are removed. The end part A of the bit is provided with a notch similar to that of the roller bits. In addition, it is provided with two blades B directed in the direction of rotation.
Действие долота, по мнению изобретател , происходит следующим образом: в твердых породах будет работать поThe action of the bit, according to the inventor, is as follows: in solid rocks will work according to
преимуществу торцева часть долота, размалыва породу, аналогично щарожечным долотам; при бурении м гких пород насечка долота забьетс породой и будет работать лезвие В аналогично долоту „рыбий хвост.advantage of the end part of the bit, grinding the rock, similar to sharloch chisels; when drilling soft rocks, the notch of the bit will be hammered by the rock and blade B will work similarly as the fishtail bit.
