Embodiment
Jump bit of the present invention, including cylinder outer shell 2 and piston rod, one end of the cylinder outer shell 2 are connected with cylinder end piece
1, the other end is connected with a seal head, and a through hole is provided with the seal head center, and described piston rod one end is slidably arranged in
In cylinder outer shell 2 and be connected with a piston 7, the other end stretches out cylinder outer shell 2 through the through hole on seal head, the piston 7 with
Cylinder outer shell 2 is tightly connected, and the piston rod is hollow piston rod, and the piston rod, which is stretched out on one end of seal head, passes through sealing
Bushing 4 slidably connects an impact head 5, and the end piston rod is socketed on sealing bush 4, and sealing bush 4 is socketed in impact head 5
On, sealing device is provided between the piston rod and sealing bush 4, the sealing device is socketed on impact head 5；
Slided in the piston rod and be provided with core hammer 6, the core hammer 6 is tightly connected with piston rod, and core hammers 6 into shape by piston rod cavity
Back pressure air cavity 64 and pressure air cavity 62 are separated into, the back pressure air cavity 64 is arranged on piston rod close to one end of impact head 5；
The inner chamber of cylinder outer shell 2 is divided into rod chamber 63 or rodless cavity 61 by the piston 7, and the rodless cavity 61 is by being arranged on work
Passage 10 on plug 7 is connected with rodless cavity 61, and one first stomata 8, the back pressure air cavity are provided with the rodless cavity 61
64 are connected by steam vent 11 with rod chamber 63, and the second stomata 9 is provided with the rod chamber 63.
