Description

Недостатки известных инстрзментов дл  ударно-перфораторнога бурени  шпуров, состо щих из съемной коронки, скрепл емой со штангой с помощью резьбового соединепи , заключаютс  в том. что на частую замену коронки, вследствие ее затуплени , затрачиваетс  много времени, а изготовление резьбового соединени  весьма трудоемко в )слови х шахты.The disadvantages of the known tools for perforation drilling holes, consisting of a removable crown, fastened to the rod with a threaded connection, are. that the frequent replacement of the crown, due to its blunting, takes a lot of time, and the manufacture of the threaded joint is very laborious in the words of the mine.

В насто щем изобретении устране гы указанные недоста.тки. Дл  скреилени  коронки со п тангоГ нри-аенено коническое соединение с углом конуса от Г26 до 230.The present invention eliminates the indicated deficiencies. For the scrapping of the crown with p tango nr-aeneno conical connection with a cone angle from G26 to 230.

На чертеже изобрал ен предлагаемый инструмент.The drawing shows the proposed tool.

Инструмент дл  ударно-перфораторного бурени  шнуров состоит из съемной коронкн I, скренл емой- со штанго 2, с помоидью конического соединени  3. Соединение 3 выполнено в виде гладкого внутреннего конуса, выточенного в коронке 1 и взаимоде1 ствую1иего с наружным конусом на конне штанги 2.The tool for percussion drilling of cords consists of a removable crown I, skrenliyom- with rod 2, with a cone joint 3. Connection 3 is made in the form of a smooth inner cone, machined into a crown 1 and interacting with the outer cone on the rod of the rod 2.

Коронка работает длительное врем  липп в том случае, если угол конусов находитс  в пределах от Г26 до . Такой угол обееиечивает также быстрое удаление коронкн со штанги при замене коронки носле ее затунлени .The crown works for a long time lipp in the event that the angle of the cones is in the range from G26 to. Such an angle also provides for the rapid removal of the crown from the rod when replacing the crown when it is drowned.

Предмет изобретени Subject invention

Конусное соединение съемных буровых коронок со нттаигами, отличающеес  тем, что угол конуса равен от до .A conical connection of removable drill bits with ntaiigi, characterized in that the angle of the cone is from to.
