A device for rapidly expanding and breaking rocks

Abstract

The invention relates to a device for quickly expanding and breaking rocks, comprising an expansion device, the expansion device is in a cylindrical shape, an opening is arranged at one end of the expansion device, the other end of the expansion device is set as a blind end, an expansion device shell is arranged on the outside of the expansion device, and the expansion device An inner bag is arranged on the inside, the middle part of the expansion device is a flat cavity, and a circular expansion device joint is arranged around the opening of the expansion device, and an expansion agent is arranged between the inner bag and the shell of the expansion device. The labor intensity of the construction personnel is simplified, and the flexible expansion device is used to realize the sealing of the rock hole by the expansion force, thus avoiding the material ejected from the rock hole and hurting people. The new method of first filling and then mixing is adopted to shorten the reaction expansion time. Reduce safety hazards and energy loss caused by previous worker operations, and use a new formula expansion agent to achieve rapid expansion, self-stirring function, and increased expansion force.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a device for rapidly expanding and breaking rocks. Background technique [0002] At present, the expansion agent on the market is used in mining, stone, concrete crushing, ore splitting, etc., the problem of accidents in the injection hole of the expansion agent, the problem of sealing the cracked rock, and the reaction time is too long. Generally, the expansion agent is poured into the rock hole. In the end, it takes more than ten to twenty hours, or even longer. The operation of the expansion agent is cumbersome, the time is not easy to control, and the energy loss in the mixing process is problematic. The entire operation process does not require manual mixing, stirring, slurry filling, etc. The operation is too complicated and professional. The mixing and pouring process is dangerous to a certain extent. Its application scenarios are too limited, and it is limited to downward ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the above-mentioned technical problems in the related art, the present invention proposes a device for rapidly expanding and breaking rocks, which can solve the problems of long reaction time of the expanding agent, accidents easily occurring in the expanding agent injection hole, swelling and cracking of the rock seal, and loss of a large amount of energy during the mixing process. Issues such as being able to pour into downward rock holes
