Description

Предлагаемый наконечник к буровой ложке предназначаетс  дл  употреблени  при бурении в лесках и суглинках. |The proposed tip to the drill spoon is intended for use when drilling in fishing lines and loams. |

На чертеже фиг. 1 изображает вид наконечника сбоку; фиг. 2 - вид его i снизу,IIn FIG. 1 is a side view of the tip; FIG. 2 - its i view from below, I

Наконечник может или составл ть ; одно целое с ложкой, или приклепь - ; ватьс  к ней.The tip can or make up; one whole with a spoon, or rivet -; vats to her.

В обычных конструкци х оба винтовых хода идут по всей длине наконечника , при чем при работе порода посту- , пает в ложку только по одной спирали, порода движуща с  по другой спирали, не может попадать в ложку, а упершись | в нее, вращаетс  вместе с ложкой, что I увеличивает затрату энергии, уменьшает | производительность бура и способствует быстрому изнашиванию инструмента. IIn conventional constructions, both screw strokes run along the entire length of the tip, and during operation, the rock will enter the spoon only along one spiral, the rock moving along the other spiral, cannot fall into the spoon, and rested | into it, rotates with a spoon, which I increases the expenditure of energy, decreases | productivity of the drill and promotes fast wear of the tool. I

В предлагаемом наконечнике только одна винтова  поверхность а доходит до верха, втора  же б имеет лишь от Va до % оборота и не доходит до цилиндрической части ложки, благодар  чему порода подаетс  обеими винтовыми поверхност ми с целью увеличени  производительности бура.In the proposed tip, only one screw surface A reaches the top, the second b has only Va to% turn and does not reach the cylindrical part of the spoon, due to which the rock is fed by both screw surfaces to increase the productivity of the drill.

Предмет изобретени .The subject matter of the invention.

Винтовой наконечник к буровой ложке , составл ющий одно целое с ложкой или преклепанный к ней, отличающийс  тем, что одна винтова  поверхность наконечника доведена до корпуса ложки, а друга -имеет лишь от 4 до / оборота и не доходит до корпуса ложки.A screw tip to a drill spoon, integral with or spoonful of a spoon, characterized in that one screw surface of the tip is brought to the body of the spoon, and the other has only 4 to / turn and does not reach the body of the spoon.
