Detailed description of the invention

A kind of rock cleavage frame head apparatus as shown in Figure 1 to Figure 3, comprise power set 1, the clutch end of described power set 1 is connected with drill bit 4, described drill bit 4 is the up big and down small frustum of a cone, on the side face of described drill bit 4, slip cap is equipped with jump bit, described jump bit and drill bit 4 are matched in clearance, under original state, drill bit 4 runs through described jump bit, the bottom of drill bit 4 passes from the lower end of jump bit, the intrados of described jump bit and the outer peripheral face of drill bit 4 suitable, described jump bit comprises the jump bit assembly I 3 and jump bit assembly II 5 that are separated from each other, the part that described jump bit assembly I 3 and jump bit assembly II 5 along the circumferential direction intercept for cylindrical body, described jump bit assembly I 3 and the top of jump bit assembly II 5 are provided with the hoop body 7 jump bit assembly I 3 and jump bit assembly II 5 waled, and the both sides on described hoop body 7 top are connected on described power set 1 by oil cylinder I 2 and oil cylinder II 6.The drill bit that the utility model uses is the up big and down small frustum of a cone, uses the bit bore of this shape to improve crushing effect, because jump bit is made up of jump bit assembly I and jump bit assembly II, jump bit assembly I and II part along the circumferential direction intercepted for cylindrical body, and the inner surface of jump bit assembly I and II and the outer peripheral face of the up big and down small frustum of a cone suitable, therefore jump bit assembly I and II entirety is in up-small and down-big shape, simultaneously the upper end of jump bit assembly I and II to be linked together the split type jump bit structure of composition one by hoop body, this structure presses to both sides, hole under impact force action, by hole avulsion, splitting is effective, and the situation that up-small and down-big structure can effectively prevent jump bit assembly from breaking because of the effect of impulsive force, the oil cylinder I of both sides setting of power set and the piston rod of oil cylinder II are connected to the top of hoop body, and hoop body drives jump bit assembly I and II motion under the driving of oil cylinder.

A kind of rock cleavage frame head apparatus as shown in Figure 1 to Figure 3, the outside on described jump bit assembly I 3 and jump bit assembly II 5 top is provided with protruding 8, the inner surface of described hoop body 7 be provided with protruding 8 with the use of groove 9.The utility model drives the motion of jump bit assembly I and II by the hoop body being arranged on jump bit assembly I and jump bit assembly II top, jump bit assembly I and II fits through protruding with hoop body and realizes coordinating of groove, the top of jump bit assembly I and II is respectively equipped with projection, the inner surface of hoop body is provided with the groove used with male cooperation simultaneously, hoop body is equipped with groove in the inner surface position of a week, be convenient to the scope of activities increasing jump bit assembly, reduce impulsive force to the effect of jump bit assembly.
