Document Type and Number:
WIPO Patent Application WO/2022/114572
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a core barrel hammer system having improved slime discharging and core cutting functions, wherein the system prevents clogging of a slime discharge pipe even while quickly discharging slime crushed by a hammer, enables smooth slime discharge on the ground, and has an improved core cutting means such that core separation and maintenance of the core cutting means are convenient. The present invention is configured by installing: a plurality of air hammers, which are connected to a rotation drive gearbox of a pile drilling machine via rods and installed in a cylindrical rotation body in which a downwardly open core formation space is formed; a slime discharge pipe for discharging slime crushed by the air hammers; and a core cutting means for cutting the lower end of a core formed inside the core formation space. A storage container support is installed above the rotation body, and a slime storage container capable of ascending/descending along the rods is formed above the storage container support, wherein the upper end of the slime discharge pipe is disposed inside the slime storage container to supply the slime. A filtration rod is installed on a suction side of the slime discharge pipe to restrict the size of the suctioned slime, and a spray nozzle for spraying compressed air is installed in the middle of the slime discharge pipe, wherein the spray nozzle is configured to break down the compressed air in the direction in which the slime is discharged.
