titleOfInvention | A kind of diamond compact bit for expiloration of coal mines |
abstract | The utility model discloses a kind of diamond compact bit for expiloration of coal mines, comprise bit matrix and diamond compact, the working end of bit matrix has along the circumferential direction been wholely set some supporters, described diamond compact welds or is bonded on supporter, have some in heat pipe arranged in parallel in described bit matrix, heat pipe top is evaporator section, bottom is condensation segment; The bottom of described heat pipe is coarser than its top, and the tube wall of heat pipe is provided with the liquid-sucking core that matching form with it closes, in heat pipe, be injected with working medium and heat pipe by end cap seal.The diamond compact bit for expiloration of coal mines designed by the utility model, its beneficial effect is: be main cutting tooth with diamond compact, and bit life is long, from good heat dissipation effect, long service life, makes not to be suitable for carry out in process of coal mining used for geological prospecting. |
