[0023] Working principle: When the upward blast hole charge loading and sealing device is in use, first place the shell between the charge loading assemblies 4, and then control the electric telescopic rod 41 to extend through an external control terminal, so as to drive the clamping members 42 to approach each other, thereby clamping the shell to be charged. Then control the motor 22 to rotate through an external control terminal, and then drive the U-shaped frame 31 under the action of the lead screw 23 and the fixing member 32, so that the U-shaped frame 31 moves along the direction of the slide groove 111, so that the charge loading assembly 4 is located directly above the upward blast hole. Immediately afterwards, control the electric telescopic rod 41 to shorten through an external control terminal, and the shell can be loaded into the blast hole. Finally, control the electric push rod 51 to extend through an external control terminal, and then drive the pressing member 53 to seal the blast hole. When it is necessary to seal blast holes of different sizes, only need to unscrew the bolt in the second jack 531 counterclockwise, and then replace the pressing member 53 adapted to the size of the blast hole. It is relatively convenient and practical and worthy of being vigorously promoted.
