Description
Предлагаетс буровой наконечник ДЛЯ ударного бурени скважип с эксцентрично расположенной режущей кромкой.A drill bit is provided for percussion drilling with an eccentrically located cutting edge.
Отличительной особенностью изобретени вл етс то, что режуща кромка наконечника выполнена в виде нескольких зубков, размещенных в диаметральной плоскости низа щтанги асимметрично по отнощению к оси штанги.A distinctive feature of the invention is that the cutting edge of the tip is made in the form of several teeth placed in the diametral plane of the lower shank asymmetrically with respect to the axis of the rod.
На чертеже схематическа изображен предлагаемый буровой каконечник .The drawing schematically shows the proposed drill tip.
В нижней часта штанги расположена режуша кромка наконечника , выполненна в виде зубков 2. Последние размещень асимметрично по отношению к оси А-А штанги ;.In the lower part of the rod there is a cutting edge of the tip made in the form of teeth 2. The latter is placed asymmetrically with respect to the axis A-A of the rod;.
Благодар такому устройству уменьшаетс ненужное дробление породы IB-средней части забо и за счет этого увеличиваетс производительность бурени .Due to such a device, unnecessary crushing of the IB-middle part of the slab is reduced and, as a result, drilling performance is increased.
