The above-mentioned solution solves the problem that when the deep hole blasting continuous grouting and sealing device in a coal mine needs to be repaired after a long period of use, the maintenance operation of the stirring mechanism 122 is not convenient because the stirring mechanism 122 is located inside the corresponding stirring tank. It can be understood that the above-mentioned solution can be used in the structure of the deep hole blasting continuous grouting and sealing device.

[0033] According to this specific embodiment, the main stirring tank 102 is provided on one side of the upper surface of the bottom plate 101, and the working frame 103 is provided on the other side of the upper surface of the bottom plate 101.

[0034] Here, the extraction mechanism 118 and the discharging mechanism 119 in this technical solution are both existing technologies, so they are not described in detail in this technical solution. The stirring mechanism 122 in this technical solution is composed of a driving motor, a stirring shaft and stirring blades, which is a common structure with stirring function in the existing technology, so it is not described in detail in this technical solution.

[0035] Wherein, the mounting frame 105 is mounted on the outer side walls of the corresponding main stirring tank 102 and the auxiliary stirring tank 104, the upper surface of the mounting frame 105 is mounted with the rotatable mounting seat, the output end of the rotatable mounting seat is provided with the lifting arm, the output end of the lifting arm is provided with the connecting arm 106, the end of the connecting arm 106 away from the lifting arm is connected to the corresponding mounting plate 121, when it is necessary to inspect and repair the stirring mechanism 122 on the main stirring tank 102 and the auxiliary stirring tank 104, the lifting arm is used to adjust the height of the connecting arm 106, so that the connecting arm 106 can drive the mounting plate 121 to be separated from the main stirring tank 102 and the auxiliary stirring tank 104. After the corresponding ends of the main stirring tank 102 and the auxiliary stirring tank 104 are connected, and the entire stirring mechanism 122 is separated from the corresponding main stirring tank 102 and the auxiliary stirring tank 104, the rotatable mounting seat is used to drive the lifting arm to rotate, so that the mounting plate 121 is rotated to the outside of the corresponding main stirring tank 102 and the auxiliary stirring tank 104, and the lifting arm is used to drive the connecting arm 106 to descend, so that the stirring mechanism 122 is lowered to a preset height, which is convenient for the staff to complete the inspection and cleaning of the stirring mechanism 122. With the above structure, the inspection of the stirring mechanism 122 can be completed outside the stirring tank body, and the operation is more convenient.

The extraction mechanism 118 is started to extract the evenly mixed slurry in the main stirring tank 102 and inject it into the coal mine through the grouting pipeline. In the blasting deep hole, the grouting and sealing process is completed. During the process in which the slurry in the main stirring tank 102 is extracted by the extraction mechanism 118, the slurry in the auxiliary stirring tank 104 is transported to the main stirring tank 102 through the discharging mechanism 119.
