Benefits of technology

The present invention provides a drilling apparatus with a head that can easily engage or disengage a rod and a driving shaft for drilling. The head is designed to match the diameter of a connected unit rod, making it simple to connect and use. Additionally, a stopper can be added to prevent the unit rod from lifting too high. This design allows for efficient drilling work and easy engagement between the unit rod and driving shaft.

Problems solved by technology

In the course of drilling, if the unit rods have relatively small diameters, it is difficult to align the driving shaft of the head with the unit rod.
In particular, even if the unit rod and the driving shaft are coaxially aligned, it is not easy to screw-couple the unit rod to the driving shaft.
Thus, it is impossible to increase the efficiency of the drilling work due to a trouble in screw-coupling of the unit rod and the driving shaft.
Since there is no separate means for balancing the support pipe, the support pipe may vibrate or may not be aligned with the center of a rotation shaft.

Embodiment Construction

[0022]Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0023]The drilling apparatus according to the present invention facilitates engagement between a unit rod and a driving shaft of the head when the ground hole is excavated, and en exemplary embodiment of the drilling apparatus is shown in FIGS. 1 to 5.

[0024]Referring to FIGS. 1 to 5, the drilling apparatus 100 having a head includes a lead 20 supported by a main body 10, a driving shaft 40 slidably installed in the lead 20 and connected to the topmost unit rod among the unit rods 70 connected to each other for drilling work, a head 30 having an actuator (not shown) for driving the driving shaft 40, and a support pipe 200 installed on the ground for preventing earth and sand around a hole excavated by the lead from collapsing.

[0025]The head 30 slidably installed along the lead 20 and is configured to elevate by a separate driver (although not shown, the driv...

Abstract

Disclosed is a drilling apparatus having a head. The drilling apparatus includes a main body, a lead supported by the main body of the drilling apparatus, a driving shaft slidably installed in the lead and having a unit rod connected thereto for performing a drilling work, and a head having an actuator for driving the driving shaft, wherein the driving shaft includes a screw coupling part formed on the outer circumferential surface of the driving shaft and screw-coupled with an end of the unit rod for performing the drilling work, and a screw coupling inducing part formed at a front end of the screw coupling part to induce screw coupling between the driving shaft and a rod screw coupling part formed at a hollow part formed at the end of the unit rod. The drilling apparatus can reduce the number of work numbers by combining the unit rod with the driving shaft, thereby increasing the efficiency of the drilling work.

Description

TECHNICAL FIELD[0001]The present invention relates to a drilling apparatus, and more particularly, to a drilling apparatus having a head, which facilitates engagement or disengagement between a rod and a driving shaft installed in the head when a drilling work is performed using a bit.BACKGROUND ART[0002]In general, a drilling apparatus is used to excavate deep holes into the ground for purposes of boring, soil testing or development of underground water. The drilling apparatus is classified into a type in which a boring work is performed while rotating a rod having a bit, and a type in which a boring work is performed by rotating a rod having a bit or a cutter and striking the bit or the cutter using the rod.[0003]A conventional drilling apparatus is disclosed in Korean Patent No. 624233. The disclosed drilling apparatus comprises a main body having a driving device such as an engine, a leader supported by the main body, and a head sliding along the leader and generating an elevati...
