Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in fig. 1-3, the high-strength mining drill rod provided by the utility model comprises a drill rod 1, wherein a reinforcing sleeve 2 is connected at the insertion end of the drill rod 1;

the inserted end of the drill rod 1 is fixedly sleeved with a reinforcing ring 3, and an active metal piece 4 is rotatably arranged on the reinforcing ring 3.

In an alternative embodiment, the reinforcing ring 3 comprises a collar 31 and a stop ring 32, the collar 31 is fixedly sleeved on the drill rod 1, the stop ring 32 is fixedly sleeved on the periphery of the collar 31, and the reinforcing ring 31 has the effect of stabilizing the strength of the joint of the drill rod 1.

In an optional embodiment, the reactive metal part 4 comprises a rotating ring 41, a reactive metal ring 42 and a protection ring 43, the rotating ring 41 is rotatably sleeved on the sleeve ring 31 and the limiting ring 32, the movable metal ring 42 is fixedly sleeved on the outer periphery of the rotating ring 41, the protection ring 43 is rotatably sleeved on the outer periphery of the reactive metal ring 42, a plurality of through holes 44 are formed in the protection ring 43, and the through holes 44 are communicated with the reactive metal ring 42, so that liquid water can contact with the reactive metal ring 42 through the through holes 44; the outer part of the protection ring 43 is fixedly sleeved with a plastic casing.
