Each example is provided as an explanation rather than a limitation of the present invention. In fact, it will be apparent to those skilled in the art that various modifications and variations may be made to the present invention without departing from the scope or spirit of the present invention. For example, a feature illustrated or described as part of one embodiment may be used in another embodiment to produce a further embodiment.

[0030] A blasthole plugging device for open-pit mining, comprising a vehicle body 1, and further comprising:

[0031] Loading box 3, as attached Figure 1 The charging box 3 is a square structure and is fixedly connected to the vehicle body 1 through support rods 2 at the four corners of the bottom. An inclined feeding port is provided on one side of the charging box 3, which is overall stable and convenient for containing slag for filling.

[0032] The inclined conveying structure and the feeding pipe 9 are as shown in the attached Figure 1 and attached Figure 3 The charging box 3 is connected to the conveying structure through an inclined connecting pipe, and is used to deliver the slag to the conveying structure. The discharge pipe 9 is fixedly arranged at the discharge port of the conveying structure and has an inverted conical structure.

[0033] Through the above structure, the conveying structure can directly deliver filling materials such as slag to the discharge pipe 9, which is convenient for pouring the slag directly into the blast hole, and the overall filling efficiency is high.

[0034] The conveying structure includes a conveying box 4 and a conveyor belt 6. Figure 3 and attached Figure 4 The conveying box 4 is fixedly connected to one side of the vehicle body 1, and a first motor 16 is provided on one side of the conveying box 4. The conveyor belt 6 is located in the conveying box 4 and is driven by the first motor 16. The first motor 16 drives the conveyor belt 6 to rotate to realize the transportation of slag.

[0035] The conveying structure also includes an arc tube, such as the attached Figure 2 , Attachment Figure 4 and attached Figure 5 An arc tube is integrally formed on one side of the discharge port of the conveying box 4, the top of the discharge pipe 9 is fixedly connected to the arc tube, and rotatably connected driving rollers 5 are provided on both sides of the conveying box 4, one end of the driving roller 5 on one side is connected to the output end of the first motor 16, and the driving rollers 5 are connected through a conveyor belt 6. A plurality of evenly distributed partition plates 7 are provided on the conveyor belt 6, and baffles 8 are provided on both sides of the conveyor belt 6. With the cooperation of the baffles 8 and the partition plates 7, slag is prevented from falling and ensured to smoothly enter the discharge pipe 9. The overall structure is simple and the transmission is stable. An inclined guide plate is provided between the discharge port of the conveying box 4 and the discharge pipe 9 to facilitate discharge.

[0036] Through the above structure, the first motor 16 drives the driving roller 5 on one side to rotate continuously, and under the transmission connection of the conveyor belt 6, drives the driving roller 5 on the other side to rotate accordingly. As the conveyor belt 6 rotates continuously, the slag filler is transported.

[0037] Auxiliary filling structure, such as attached Figure 1 and attached Figure 2 , the two ends of one side of the vehicle body 1 are rotatably arranged, and when the electric telescopic rod 14 is contracted, it drives the auxiliary filling structures on both sides to move toward the middle, so as to push the slag into the blasthole. A fixed plate 10 is provided on one side of the bottom end of the vehicle body 1, and the auxiliary filling structure includes a pair of rotating shafts 11 arranged at the top of the fixed plate 10, and the rotating shafts 11 are provided with gears 12 that are rotatably connected, and the gears 12 are meshed with each other. The connecting rods 13 are respectively integrally formed on one side of the gears 12, and the two ends of the electric telescopic rod 14 are respectively hinged to the connecting rod 13, and one end of the connecting rod 13 is provided with a push plate 15.

[0038] Through the above structure, as the electric telescopic rod 14 continues to shrink or extend, the connecting rod 13 drives the gear 12 to rotate, and the gears 12 on both sides rotate in the middle or on both sides at the same time, so that the push plate 15 moves to the middle or to both sides at the same time, which helps to push the slag on the ground into the blasthole, and the overall work efficiency is high.

[0039] Combined with Figure 7 A second motor 17 is provided at the top of the charging box 3, and a stirring shaft 18 rotatably connected and driven by the second motor 17 is provided in the charging box 3. The stirring shaft 18 is provided with a plurality of stirring blades 19 symmetrically and evenly distributed. The bottom end of the charging box 3 is provided with an inclined plate, and the bottom end of the stirring shaft 18 is rotatably connected to the inclined plate through a bearing.

[0040] Through the above structure, the second motor 17 drives the stirring shaft 18 to rotate continuously, and the stirring blades 19 on the stirring shaft 18 rotate accordingly, so as to mix and stir the slag in the charging box 3, facilitate the addition of other filling materials, ensure uniform mixing, and achieve good filling effect.

[0041] Combined with Figure 4 and attached Figure 6 A fixedly connected pipe sleeve 20 is provided on one side of the bottom end of the discharge pipe 9, a third motor 21 is provided on one side of the pipe sleeve 20, a rotatably connected driving shaft is provided on one side of the pipe sleeve 20, one side of the driving shaft is connected to the output end of the third motor 21, a sliding rod 22 with a sliding connection is inserted in the pipe sleeve 20, a fixedly connected limiting ring 23 is provided at one end of the sliding rod 22, a connecting rod 24 is provided on the driving shaft, and the other end of the connecting rod 24 extends to one side of the limiting ring 23 and is rotatably connected to the limiting ring 23.

[0042] Through the above structure, the third motor 21 drives the driving shaft to rotate continuously, and then drives the connecting rod 24 to rotate continuously. Since one end of the connecting rod 24 extends into the limiting ring 23 and is rotatably connected to the limiting ring 23, as the connecting rod 24 rotates continuously, the sliding rod 22 is driven by the limiting ring 23 to move back and forth continuously in the pipe sleeve 20, and the discharge pipe 9 can be continuously knocked to prevent slag from accumulating at the bottom end of the discharge pipe, ensuring that the slag falls evenly, further improving the filling efficiency.

[0043] Working principle of the present invention:

[0044] First, pour the slag directly into the charging box 3 through the side discharge port. When other fillers need to be mixed in, pour the other fillers into the charging box 3 first, and then start the second motor 17. The second motor 17 drives the stirring shaft 18 to rotate continuously, and the stirring blades 19 on both sides of the stirring shaft 18 move accordingly, so as to evenly mix the fillers in the charging box 3 and facilitate subsequent filling operations.

[0045] Then, the vehicle body 1 is opened to the vicinity of the blasthole so that the discharge pipe 9 is aligned with the blasthole. Under the action of gravity, the slag filler enters the conveying box 4 through the inclined connecting pipe, and the first motor 16 is started. The first motor 16 drives the driving roller 5 on one side to rotate. Under the transmission connection of the conveyor belt 6, the driving rollers 5 on both sides rotate. With the continuous rotation of the conveyor belt 6 and with the cooperation of the baffle 8 and the partition plate 7, the slag is continuously conveyed.

[0046] When the slag reaches the discharge port of the conveying box 4, with the assistance of the guide plate, the slag can be directly poured into the discharge pipe 9 continuously to fill the blasthole continuously. At this time, the electric telescopic rod 14 is started to contract, and the gear 12 is driven to rotate through the connecting rod 13, so that the push plate 15 moves to the middle at the same time, which is convenient for pushing the slag on the side of the blasthole into the blasthole. As the electric telescopic rod 14 continues to extend, the push plate 15 moves to both sides, and the earth is pushed again for filling. The efficient and accurate filling method greatly reduces manual operation, improves filling efficiency, and avoids manual direct operation of the blasthole filling process, reduces safety hazards, and improves safety.

[0047] During the filling process, the third motor 21 is started, and the third motor 21 drives the driving shaft to rotate continuously, thereby driving the connecting rod 24 to rotate continuously. Since one end of the connecting rod 24 extends into the limiting ring 23 and is rotatably connected to the limiting ring 23, as the connecting rod 24 rotates continuously, the sliding rod 22 is driven by the limiting ring 23 to move back and forth continuously in the pipe sleeve 20, and the discharge pipe 9 can be continuously knocked to prevent slag from accumulating at the bottom end of the discharge pipe, ensure that the slag falls evenly, and further improve the filling efficiency.
