[0017] (1) A device for filling blasting gun mud in a mine. During use, the device is placed on the upper side of a blast hole to be filled, and the connecting sleeve and the blast hole are made to correspond to each other. The blasting gun mud to be filled is placed between two sets of movable baffles and located on the upper side of the connecting sleeve. The two sets of movable baffles limit the blasting gun mud to ensure its stability. Then, the cam plate is rotated through the driving mechanism. The outer wall of the cam plate away from the axis will approach the upper side wall of the movable connecting plate. The movable connecting plate will be forced to move downward with the fixed pressure rod, and the connecting mechanism will be connected. The sliding rod will move downward with the limit plate, the elastic element will be compressed under force, and finally the fixed pressure rod will contact the upper wall surface of the blasting gun mud, and force the blasting gun mud to pass through the inside of the connecting sleeve and finally enter the inside of the blasting hole. As the cam plate rotates, its outer wall away from the axis will move away from the upper wall surface of the movable connecting plate, the elastic element will stretch and return to its original state, and the movable connecting plate will return to its original position with the fixed pressure rod, and then the second group of blasting gun mud will be filled. Compared with manual filling, it will be more labor-saving and reduce labor intensity.

[0018] (2) This invention is a mining blasting gun mud filling device. During use, by rotating the auxiliary knob in the forward direction, the distance adjustment rod begins to rotate in the forward direction. Under the limiting action of the guide slide bar and the connecting slot, the two sets of connecting slides approach each other, thereby reducing the distance between the two sets of movable baffles. In this way, corresponding adjustments can be made according to the outer diameter of the required blasting gun mud, thereby improving practicality.

[0019] (3) This invention is a mining blasting mud filling device. During use, the movable wheel assembly and the auxiliary handle cooperate with each other to facilitate the movement of the device. In addition, the mud to be blasted is placed one by one from the position between the front ends of the two sets of movable baffles. By rotating the four sets of transmission rollers, the two sets of conveyor belts start to rotate and transport the blasting mud to the position of the connecting sleeve. There is no need to place the blasting mud at the position of the connecting sleeve in groups, which facilitates the use of the device.

[0020] (4) A device for filling mud for blasting mines. The invention starts a driving motor, and the output end of the driving motor rotates the cam plate. After the device is placed in the blast hole to be filled, the connecting rod can be rotated in the forward direction until the positioning bolt and the positioning connecting plate are separated. Then, the positioning cone can be fixed into the corresponding ground through a tool, so that the device can be positioned to ensure its stability during operation. BRIEF DESCRIPTION OF THE DRAWINGS
