Title: Swivel joint for boring device
Inventor: ENDO TETSUYA
IPC: E21B17/03
Filed: 1994-12-29
Abstract: PURPOSE: To enhance the excavating by lessening the outside diameter of the drain hole part of an extension rod, and forming a drainage hole greater than this outside diameter in a swivel body. CONSTITUTION: A water feeding groove is furnished at the end 13 of an extension rod 17, and the outside diameter of the rod 17 near a drainage hole is made small, and a greater drainage hole is provided in communication with a large diameter part 23 straddling the contour of a male thread part 4A on the rod 17. Fluid such as water supplied from a supply port 12 is passed through a supply hole 9 and the bore part 20 of the rod 17 and exhausted from near a bit of an excavating rod in an inner pipe 8. Slime produced from excavation is passed through an exhaust passage 19 and exhausted to outside via a drainage hole and drain port 11, and because the diameter of the drainage hole is enlarged and the outside diameter of the rod 17 near the hole is lessened, slime exhaustion can be done smoothly to lead to enhancement of the excavating efficiency.
