Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

Example 1

As shown in fig. 1 to 4, the jump ring seat for a directional core drill of embodiment 1 includes a jump ring seat body 1, and a marking assembly is disposed on an inner wall of the jump ring seat body 1, and the marking assembly is configured to leave a base point mark on a core to determine a circumferential direction of the core inside a rock formation after the core is taken out.

The marking assembly comprises at least one scoring piece, the scoring pieces are arranged in an unequal manner, and the scoring piece is used for scoring a scratch on the rock core.

The scoring member is an alloy blade 3.

The alloy cutter head 3 protrudes out of the inner wall of the clamp spring seat body 1.

The alloy tool bit 3 is welded with the inner wall of the clamp spring seat body 1.

The alloy cutter head 3 is provided with six, and the six alloy cutter heads 3 are divided into two groups, and each group comprises 3.

The feeding end of the alloy cutter head 3 is provided with a chamfer 31 with an angle of 45 degrees.

When the drill rod is used in the embodiment 1, in the drilling process of a drill rod, a rock core passes through the jump ring seat body 1, and six nicks 6 are left on the rock core by the alloy cutter head 3;

after the core is extracted to the ground, the circumferential direction of the core in the rock stratum can be judged according to the nick 6.

Example 2

As shown in fig. 5 to 6, embodiment 2 is based on embodiment 1, except that the alloy bit 3 is slidably fitted to the inner wall of the jump ring housing body 1, and the sliding direction of the alloy bit 3 is arranged in the radial direction of the jump ring housing body 1.

An accommodating cavity 11 is formed in the inner wall of the clamp spring seat body 1, a tool apron 2 is arranged in the accommodating cavity 11 in a sliding mode, a limiting bump 12 for limiting the tool apron 2 to fall off is arranged at the opening of the accommodating cavity 11, and an elastic piece is clamped between the tool apron 2 and the outer wall of the clamp spring seat body 1; the alloy cutter head 3 is detachably and fixedly connected with the cutter holder 2.

The elastic element is a pressure spring 4.

Embodiment 2 during the use, during the drilling rod process of drilling, when meetting comparatively hard stratum, alloy tool bit 2 slides to the outer wall direction of jump ring seat body 1, avoids alloy tool bit 3 to leave too deep nick 6 on the rock core by force, makes alloy tool bit 3 wear or collapse too fast, plays the guard action to alloy tool bit 3.

Example 3

Example 3 is based on example 1, as shown in fig. 7, with the difference that the marking assembly includes at least one color marking member, the color marking members being arranged in unequal intervals, the color marking members being used to color mark the core.
