[0023] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of an open-pit mine blasting hole filling machine of the utility model in conjunction with the accompanying drawings.

[0024] like Figures 1 to 4 As shown, an open-pit mine blasting hole filling machine of the utility model includes a bottom plate 1, and a bracket 2 and a battery 7 are arranged on the top surface of the bottom plate 1. A silo 3 for storing fillers is arranged on the bracket 2, and a first discharge pipe 5 is connected to the bottom end of the silo 3, the first discharge pipe 5 passes through the bottom plate 1, and a switch control valve 6 for controlling its opening and closing is arranged on the side wall of the first discharge pipe 5, and the switch control valve 6 is electrically connected to the battery 7. When the discharge port of the first discharge pipe 5 is aligned with the blasting hole, the switch control valve 6 is started, so that the filler in the silo 3 is directly filled into the blasting hole through the first discharge pipe 5. At the same time, universal wheels 4 are also distributed on the bottom surface of the bottom plate 1, and the universal wheels 4 can facilitate the movement of the open-pit mine blasting hole filling machine. The universal wheels 4 are preferably universal wheels 4 with brakes, so that the position of the open-pit mine blasting hole filling machine is fixed. In order to facilitate the alignment between the first discharge pipe 5 and the blasting hole more quickly, a second discharge pipe 23 is connected to the first discharge pipe 5.

[0025] Preferably, a second electric push rod 14 with a telescopic end facing downward is provided on the bottom plate 1, the second electric push rod 14 is electrically connected to the battery 7, and a pressure plate 15 is provided at the telescopic end of the second electric push rod 14. After the blasting hole is filled with filler, the open-pit mine blasting hole filling machine is moved so that the pressure plate 15 is aligned with the blasting hole, and then the second electric push rod 14 is started, and the second electric push rod 14 presses the filler in the blasting hole through the pressure plate 15, thereby reducing the gap between the fillers and improving the blasting effect of the ore.

[0026] like Figure 3As shown, the top surface of the bottom plate 1 is provided with a first motor 13, and the first motor 13 is electrically connected to the battery 7. A loading tray 21 is rotatably provided on the bottom surface of the bottom plate 1, and a rotating shaft penetrating the bottom plate 1 is provided on the loading tray 21, and the rotating shaft and the bottom plate 1 are rotatably arranged, and the output end of the first motor 13 is connected to the loading tray 21 through the rotating shaft. A through hole with the same diameter as the first discharge pipe 5 is opened on the loading tray 21, and the second discharge pipe 23 is arranged in the through hole, and the second electric push rod 14 is arranged on the bottom surface of the loading tray 21. In this way, when the filler is filled into the blasting hole and the pressure plate 15 is required to compact the filler in the blasting hole, the first motor 13 can be directly started, and the first drive loading tray 21 rotates, so that the second electric push rod 14 drives the pressure plate 15 to rotate to the top of the blasting hole, and then the second electric push rod 14 is started, and the second electric push rod 14 presses the filler in the blasting hole through the pressure plate 15, which is more convenient to operate. Of course, when the blasting hole needs to be supplemented with fillers, the first motor 13 is started again, and the first motor 13 drives the loading plate 21 to rotate, so that the second discharge pipe 23 rotates to the top of the blasting hole again, and then the switch control valve 6 is opened to allow the fillers in the silo 3 to be supplemented into the blasting hole through the first discharge pipe 5 and the second discharge pipe 23. It should be noted that the bottom surface of the first discharge pipe 5 is flush with the bottom surface of the bottom plate 1 to facilitate the rotation of the loading plate 21. In order to prevent the second discharge pipe 23 and the pressure plate 15 from rubbing or colliding with the bottom surface when the open-pit mine blasting hole filling machine moves, a connecting column 22 is distributed on the bottom surface of the bottom plate 1, and the universal wheel 4 is located at the bottom end of the connecting column 22.
