Description

Technical Field [0001] The present invention relates to a rod feeder for a drilling machine,

The present invention relates to a rod feeder for a perforator, and more particularly to a rod feeder for a perforator provided with a rod feed means for easily feeding a piercing drill rod used in a drilling operation to a lid.

A typical perforator is an oscillator method that rotates a bit with an underground drilling device for underground water development, geological survey, and drilling, and R.C.D. method for applying pressure simultaneously with rotation.

In the past drilling operation, the perforator equipped with the hydraulic drive unit and the load conveying car supplying the load due to the deepening of the piercing depth had to be supplied and operated separately from the perforator. However, It has been pointed out that there is an additional burden on the equipment and labor costs for such a load-carrying car because the load-carrying kaka is not put in separately, or the ground is uneven so that the load-carrying car is accompanied by a separate horizontal holding device.

To this end, a rod mounting device for a perforator disclosed in Korean Patent No. 10-1355188 includes a main body including an engine and a hydraulic pressure supply device, a reader vertically extended on the front of the main body, And a drilling unit provided at a front end of the rod connected to the head and for excavating the ground while lifting or rotating together with the rod, A rod mounting section provided on the main body or the base section for providing a space in which the rods are loaded; and a rod mounting section for mounting the rod mounted on the rod mounting section to the head section And a sliding driving unit for slidingly driving the base unit in the front-rear direction of the main body.

Such a perforator load mounting apparatus has a high installation cost due to the addition of a crane unit equipped with a load grasping unit, and the center of gravity due to the load mounting portion inclined upward by the support member provided on the perforator base member is not stable It causes trouble to work according to the terrain.

In addition, a drilling apparatus disclosed in Korean Patent Publication No. 10-2011-0027429 includes a head mounted on a main body of a drill, a head slidably installed on the lead and having a drive shaft coupled with the drill rod, A tool clamping means for engaging and disengaging the drill rod or the drill rod provided on the lead and coupled to the lead; The cartridge means disclosed in the manner in which the drill rods are installed and the cartridge means for supplying and withdrawing the drill rods are provided is a means for carrying out the gripping operation of gripping a plurality of rods, In particular, in the case of uneven grounds, the work of maintaining the ground of the perforator .
