| titleOfInvention | A kind of drill bit of expiloration of coal mines |
| abstract | The utility model discloses a kind of drill bit of expiloration of coal mines, comprise bit matrix and diamond compact, described diamond compact is welded on bit matrix, it is characterized in that the working end of bit matrix has along the circumferential direction been wholely set some supporters, supporter is provided with groove, be provided with described diamond compact in groove, described diamond compact is higher than supporter top; There is in described bit matrix some first heat pipes, described first heat pipe quantity and position identical with supporter and supporter corresponding; Described supporter is stretched at described first heat pipe top; First heat pipe is evaporator section near one end of working end, the other end is condensation segment; The tube wall of the first heat pipe is provided with liquid-sucking core, in the first heat pipe, is injected with working medium and by end cap seal.This bit life length take diamond compact as main cutting tooth, and the anti-wear performance of composite sheet is more than 20-40 times of carbide alloy, from good heat dissipation effect. |
