Description
Изобретение относитс к буровой технике, в частности к шарошкам, используемым в долотах дл сплошного и колонкового бурени .The invention relates to a drilling technique, in particular to roller cones used in chisels for continuous and core drilling.
Известна шарошка бурового долота, зубь периферийного р да которой соединены между собой перемычками.The known drill bit of the drill bit, the teeth of the peripheral row of which are interconnected by jumpers.
Однако при проходке пластичных и в зких пород пространство между зубь ми забиваетс частицами выбуренной породы, что снижает механическую скорость и проходку на долото .However, when plastic and viscous rocks are sown, the space between the teeth is clogged with particles of drill cutting, which reduces the mechanical speed and penetration of the bit.
С целью улучшени условий промывки забо скважины в перемычках выполнены сквозные отверсти .In order to improve the conditions for flushing the bottom hole in the jumpers, through holes are made.
На чертеже изображена предлагаема шарошка .The drawing shows the proposed roller cutter.
Шарошка имеет периферийный р д зубьев 2, соединенных перемычками 3. В основании перемычек выполнены сквозные отверсти 4, направленные от зубчатой поверхности к ее наружной поверхпости.The roller cutter has a peripheral row of teeth 2 connected by bridges 3. At the base of the bridges there are holes through 4 directed from the toothed surface to its outer surface.
