the self-explosion mixing device comprises a shaft body (3) hinged to a frame body (2), a stirring rod (4) is fixedly mounted on the side wall of the shaft body (3), a gear (5) is assembled on the side wall of the shaft body (3) and positioned at the upper end of the stirring rod (4), a connecting rod (6) is arranged on the side wall of the shaft body (3) at the upper end of the gear (5), and a gear (7) meshed with the gear (5) is arranged at the end part of the connecting rod (6); and a traction rope (8) is wound on the connecting rod (6).
Preferably, the stirring rod (4) is a square plate body;
preferably, the stirring rod (4) is a cylindrical rod body;
a method for using a hole mixed self-explosion bag comprises the following steps;
the bag body (1) is bound on the pipe body together with the frame body (2), the pipe body extends into the hole, after the bag body (1) reaches a designated position, the traction rope (8) is pulled, the traction rope (8) drives the gear (5) to rotate, the stirring rod (4) is further driven to puncture the bag bodies (1-2) and (1-3) at two ends, the material isocyanate and the special polyether in the two bag bodies are fully stirred and mixed, the mixed material expands and explodes, and the pipe body and the hole wall are sealed and bonded by the exploded material.
The invention has the advantages that the device is bound in the pipe body and extends to a deeper part in a hole or an operation part which is difficult to construct, and isocyanate and special polyether are mixed and stirred by the self-explosion mixing device, so that the device can realize plugging by chemical reaction expansion and self-explosion.
