DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a rod guide/coupling device for a drilling machine such as a Crawlad 9-rill. - (Prior Art) As shown in Figures 7 and 8 of the rod guide, the left support member (4) on which the drilling machine (1) is movably mounted is arranged in the mounting frame (5) at the front part. , consists of a pair of right hydraulic cylinders (al (a),
During drilling work, use the hydraulic cylinder (hydraulic cylinder body) (as shown in Figure 7).
Clamp recess at the tip of the rod (b) (b) in a) (c) (
The rods (2a) and (2b) are guided by the cl so that they can be moved forward and backward and rotated, and when the rods 9 are separated, the connected rods (2a) are connected to the hydraulic cylinders (a) (al). To tighten the clamp recess (cl), hold the clamp and rotate the rod (2b) from the drilling machine (1) K. Separate the threaded connection between (2a) and (2b). In addition, the structure is such that they are connected by reverse rotation.

(Problems to be Solved by the Invention) The rod guide/connection device of the drilling machine is such that the 9-axis axis of the rod tends to fluctuate to the left or right during drilling, and when the hydraulic cylinder is actuated to clamp the rod, as shown in FIG. Rod 9 as shown
In some cases, the rod may be held in an eccentric position, making it difficult to center the rod when cutting, separating, connecting, and connecting. It may also cause bending of the rod, seizing of the threaded connection, and impact shock during drilling. Due to the generation of rotational force, the cutting edge of the threaded connection part becomes even more inner ring, and this tendency is especially noticeable in the case of rock crushers that use both rotational force and impact force. There are problems such as the inability to separate the two.
