Problems solved by technology

[0002] When constructing a pile foundation, a pile driver is needed. The pile driver drives the drill bit to rotate through the power device to drill the foundation into piles. If the foundation is relatively hard, the impactor on the existing pile driver is matched with the rock drill bit structure. Slow drilling speed and low work efficiency

Abstract

The invention discloses a rock-entering drill bit structure manufactured by utilizing the principle that a rock stratum is easy to break after being cut into single cylinders. The rock-entering drill bit structure is high in rock stratum layer drilling speed and high in efficiency and is used in cooperation with a pile machine impactor. The rock-entering drill bit structure comprises a rock-entering drill bit and an inner drill bit arranged in the rocking-entering drill bit. An air channel is formed in the middle of the inner drill bit. A plurality of blowing channel holes communicated with the lower end of the air channel are formed in the conical head of the lower end of the inner drill bit uniformly. The blowing channel holes are communicated with an internal cavity of the rock-entering drill bit. A plurality of inner drill bit alloy protecting teeth are arranged on the surface of the conical head of the lower end of the inner drill bit. A plurality of rock-entering drill bit alloy protecting teeth are arranged on the inner wall and the lower end head of the rock-entering drill bit. A plurality of reverse muck notches are formed in the lower end head of the rock-entering drill bit uniformly. A plurality of reverse muck air channels communicated with the reverse muck notches are formed in the rock-entering drill bit.

Description

technical field [0001] The invention relates to a power head of a pile driver, in particular to a rock drilling bit structure matched with an impactor on a pile driver. Background technique [0002] When constructing a pile foundation, a pile driver is required. The pile driver drives the drill bit to rotate through the power device to drill the foundation into piles. If the foundation is relatively hard, the impactor on the existing pile driver is matched with the rock drill bit structure. Drilling speed is slow and work efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rock-entrying drill bit structure used in conjunction with the impactor on the pile driver with fast rock-entry speed and high efficiency. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: the rock drill bit structure, including: the rock drill bit an...
