Abstract
Изобретение относитс к породо- разрушающему инструменту и позвол ет повысить эксплуатационную стойкость коронки и скорость бурени . Коронка содержит корпус 1, рабочий торец которого разделен , промывочными пазами 4 на секторы 3, армированные режущими вставками (в) 2 из алмазоносного материала. Причем В 2 выполнены в плане трапецеидальной формы, обращенной большим основанием в сторону периферии. Длины большего и меньшего оснований выбраны в соответствии со специальным выражением. По крайней мере, часть В 2 выполнена с прокладками из абразивного материала (AM), установленными на разных В 2 с ради- альным смещением. Коронка имеет по крайней мере одну В 6а из AM и установлена между пазом 4 и перед В 2 по ходу вращени коронки. Разрушенна в ходе бурени порода через пазы 4 удал етс из забо . Прргчем AM прокладок при износе попадает- под торец В 2 и обнажает алмазные зерна. 3 з.п. ф-лы, 3 ил. (Л СThe invention relates to a rock-destroying tool and makes it possible to increase the operational durability of the crown and the speed of drilling. The crown comprises a housing 1, the working end of which is divided by flushing grooves 4 into sectors 3 reinforced with cutting inserts (c) 2 of diamond-bearing material. And B 2 is made in terms of trapezoidal shape, facing a large base towards the periphery. The lengths of the larger and smaller bases are chosen in accordance with the special expression. At least part B 2 is made with gaskets of abrasive material (AM) mounted on different B 2 with radial displacement. The crown has at least one B 6a of AM and is installed between groove 4 and in front of B 2 as the crown rotates. The rock, destroyed during drilling, is removed through the grooves 4 from the bottom. Prrchem AM gaskets when worn falls under the end of the B 2 and exposes the diamond grains. 3 hp f-ly, 3 ill.
