Technical field

The present invention relates to a kind of rock bit, specially a kind of combined cone type cutting head with chip space belongs to probing Technical equipment field.

Background technique

Rock bit is a kind of most popular drilling bit.Rock bit has impact when rotated, crushes and cut The effect of broken formation rock is cut through, so, rock bit can adapt to soft, medium, hard various stratum, existing rock bit When some gear wheel damages, needs to take out on the ball between gear wheel and the shaft of bit leg, then realizes and replacement is removed to gear wheel, Bit leg connection integrated with palm seat, the total quality of drill bit are big, it has not been convenient to replace to some independent gear wheel, and existing During the work time, the clast that gear wheel squeezes, cutting rock stratum generates is easily accessible between gear wheel bottom surface and bit leg rock bit Gap in, and enter at sealant.As the increase and clast of clast rub for a long time with sealant, sealant meeting It is gradually worn, and then clast can seriously affect the normal work of the Bearning mechanism of connection gear wheel and bit leg, even result in axis Failure is held, and then scraps entire rock bit.

Summary of the invention

The object of the invention is that providing a kind of combined type rotary drill with chip space to solve the above-mentioned problems Head.

The present invention through the following technical solutions to achieve the above objectives: a kind of combined cone type cutting head with chip space, Including connecting rod, installation screw rod, gasket, detent block, the palm seat, mounting groove, bit leg, gear wheel, chip space, reinforcing rib, standing screw, Connecting shaft, sealing block and shield；Installation screw rod is fixed on the upper surface of the connecting rod, so the upper surface of connecting rod Be fixed with one layer of gasket on surface, the gasket be stuck between connecting rod and palm seat and can deformation, the bottom of the installation screw rod Both ends be fixed with detent block, the palm seat is mounted on installation installation screw rod, and there are place the recessed of detent block on the palm seat The upper end of slot, the palm seat is provided with mounting groove, and the bit leg is stuck in mounting groove, and the standing screw passes through bit leg for bit leg It is fixed together with palm seat, the upper end of the bit leg is fixed with connecting shaft, and the other end and gear wheel of the connecting shaft are connected to one It rises, is provided with chip space on the side of the palm seat, there are three the chip spaces and is distributed in the side downward spiral of palm seat, institute The two sides for stating chip space are fixed with reinforcing rib, and sealing block is fixed on the lower end surface of the gear wheel, is fixed on the sealing block Shield, the shield are inclined outwardly 45 degree of settings, and the bit leg can freely be dismantled from palm seat and palm seat can be free From installation screw rod on dismantle.

Further, in order to enable clast can be rotated with chip space to the bottom of chip space and discharge, the chip removal There are three slots and is distributed in the side downward spiral of palm seat.

Further, in order to enhance the intensity for slapping seat, the two sides of the chip space are fixed with reinforcing rib.

Further, in order to prevent in use because being separated between connecting rod and palm seat caused by vibration, the gasket Be stuck in connecting rod and the palm seat between and can deformation.

Further, in order to enable entire drill bit can individually repair replacement components in maintenance, the bit leg can It is freely dismantled from palm seat and palm seat can be dismantled freely from installation screw rod.

Further, in order to enable connecting rod and palm seat are less likely to occur to slide relatively, there are place to block on the palm seat The groove of position block.

Further, in order to enable clast is not easily accessed at the gap between bit leg and gear wheel, the shield is outside Tilt 45 degree of settings.

The beneficial effects of the present invention are: combined cone type cutting head structure connection is compact, using simple, design rationally, row It considers to be worth doing there are three slots and in the side downward spiral distribution of palm seat, clast can be rotated to the bottom of chip space side by side with chip space Out, the two sides of chip space are fixed with reinforcing rib, can enhance the intensity of palm seat, caused by effectively preventing palm seat because of heel and toe wear Strength reduction is broken, gasket be stuck in connecting rod and the palm seat between and can deformation, vibration can be effectively absorbed, prevent from making With in the process because being separated between connecting rod caused by vibration and palm seat, bit leg can freely from the disassembly of palm seat and palm seat can freely from It is dismantled on installation screw rod, entire drill bit can individually repair replacement components in maintenance, relative to one-piece drill bit, maintenance Get up more simple and fast, there are the grooves for placing detent block on palm seat, so that connecting rod and palm seat are less likely to occur relatively Sliding, shield are inclined outwardly 45 degree of settings, so that clast is not easily accessed at the gap between bit leg and gear wheel, prevent Clast influences the normal work of the Bearning mechanism of connection gear wheel and bit leg.
