Description
Известные двухдолотчатые коронки не обеспечивают скол крупных кусков породы дл опробовани .Known double-bit crowns do not provide chipping of large pieces of rock for testing.
Предлагаема двухдолотчата коронка не имеет этого недостатка, так как она выполнена П-образной формы.The proposed double-bit crown does not have this drawback, since it is made U-shaped.
На чертеже показана двухдолотчата коронка в двух проекци х.The drawing shows a two-bit crown in two projections.
Коропка имеет два пр мых режущих лезви 1, армированных твердосплавными резцами 2, и хвостовик с конусом 3 дл соединени с буровой штангой пневматического отбойного молотка.The blade has two straight cutting blades 1 reinforced with carbide-tipped cutters 2 and a shank with a taper 3 for connection to the drill rod of a pneumatic pick hammer.
При работе коронка образует две параллельные борозды в горной породе . Когда глубина борозд достигает 3 см, проба породы, наход ща с между бороздами и представл юща собой крупные куски, отслаиваетс от основного массива.When working, the crown forms two parallel grooves in the rock. When the depth of the furrows reaches 3 cm, a rock sample located between the furrows, which is a large piece, exfoliates from the main body.
Предмет изобретени Subject invention
Двухдолотчата коронка дл отбора бороздовых проб, армированна твердосплавными резцами, отличающа с тем, что, с целью одновременного бурени двух параллельных борозд отбойным молотком и получени крупных кусков породы дл опробовани , она выполнена П-образной формы.Double-bit crown for sampling furrow samples, reinforced with carbide cutters, characterized in that, in order to simultaneously drill two parallel furrows with a jackhammer and obtain large pieces of rock for testing, it is made U-shaped.
