Description

Отличие коронки дл  бурени  котлов в глубинной части шпуров, выполненной в виде кор-пуса с укренленными в нем ненодвижнымн и раздвижными резцами, заключаетс  в разведении раздвижных резцов принудительно, за счет непосредственного воздействи  на резцы силы реакции сопротивлени  породы, а также в наличии в корпусе коронки отверстий дл  поступлени  сжатого воздуха или промывочной жидкости ПОД лезви  Коропки. Такое выполнение коронки обеспечивает упрощение и удешевление ее изготовлени  и непрерывное удаление в процессе бурени  из забо  буровой мелочи.The distinction of a crown for drilling coppers in the deep part of boreholes, made in the form of a corpus with nonmovable and sliding incisors fixed in it, consists in diluting the incisor incisors by force, due to the direct effect on the incisors of the resistance to rock resistance, and also in the crown openings for the entry of compressed air or flushing fluid under the Koropka blade. Such an embodiment of the crown provides for simplification and cheapening of its manufacture and continuous removal of the drill from the drilling fines during the drilling process.

На фиг. 1 изображена коронка в процессе введени  в шпур; на фиг. 2 - то же, в процессе бурени .FIG. Figure 1 shows a crown during insertion into the hole; in fig. 2 - the same in the process of drilling.

Коронка состоит из корпуса 1, снабженного двум  неподвижными резцами 2 и двум  раздвижны.ми резцами 3, укрепленными в корпусе при помощи осей 4.The crown consists of a body 1, equipped with two fixed cutters 2 and two sliding cutters 3, fixed in the case with the help of axles 4.

Резцы армированы твердым сплавом.Cutters are reinforced with hard metal.

Коронка вводитс  в шпур со сведенными раздвижными резцами. При упоре раздвижных резцов в забой, под воздействием на них силы реакции сопротивлени  породы, осуществл етс  принудительное раздвижение резцов.The crown is inserted into the bore-hole with collapsed sliding incisors. When the sliding incisors stop in the face, under the influence of the resistance force of the rock on them, the incisors are forced to open.

Силы реакции сопротивлени  пород направлены на резцы эксцентрично по отношению к их ос м.Reaction forces of rock resistance are directed to the cutters eccentrically with respect to their axes.

В корпусе коронки имеютс  отверсти  дл  поступлени  сжатого воздуха или промывочной жидкости под лезви  коронки (на чертеже не показаны).There are openings in the crown housing for the entry of compressed air or flushing fluid under the crown blades (not shown).
