Abstract
Изобретение относитс к горному делу, конкретнее - к породоразрушающим инструментам , и м.б. использовано на буровзрывных работах. Цель изобретени - расширение эксплуатационных возможностей устройства при одновременном повышении надежности его в работе. Устройство состоит из корпуса 1, св занного через штифт 3 и паз 2 с гильзой 4. Внутри корпуса 1 и гильзы 4 помещен подвижный подпружиненный пружинами 13 и 15 толкатель 11 с ножами 8, взаимодействующими с роликами 6, размещенными в пазу 5 на гильзе 4, На переднем конце гильзы 4 установлена коронка 16. Враща устройство против часовой стрелки, выбуривают шпур в горной породе. По достижении проектной глубины вращение мен ют на противоположное. При этом ножи 8 поворачиваютс на оси 10 и формируют в шпуре котловую полость 6 ил.The invention relates to mining, more specifically to rock-cutting tools, and m. used in drilling and blasting operations. The purpose of the invention is to expand the operational capabilities of the device while increasing its reliability in operation. The device consists of a housing 1 connected via a pin 3 and a groove 2 with a sleeve 4. Inside the housing 1 and the sleeve 4 is placed a movable spring-loaded spring 13 and 15 pusher 11 with knives 8 interacting with rollers 6 placed in a groove 5 on the sleeve 4, At the front end of the sleeve 4 a crown 16 is installed. Rotating the device counterclockwise, a hole is drilled in the rock. Upon reaching the design depth, the rotation is reversed. In this case, the knives 8 rotate on the axis 10 and form the boiler cavity 6 sludge in the hole.
