[0002] Open-pit deep-hole blasting is a major development direction in modern engineering blasting technology. It is widely used in open-pit mining, large-scale quarrying, railway (highway) cutting, and hydropower project foundation excavation. Deep-hole blasting significantly improves blasting quality, maximizes blasting efficiency, and allows for faster completion of blasting objectives. Selecting appropriate blasting parameters and optimizing the blasting process are fundamental to improving efficiency and reducing costs. The main blasting process involves delivering explosives into the blast hole and then detonating them using a detonating device.

[0003] Existing medium-deep hole blasting charging devices have the problem of powdered explosive residue during use. Specifically, after the powdered explosive is loaded into the device and discharged, some of the explosive will adhere to the inner wall of the device. However, the existing technology lacks effective means to clean the inner wall. This residue may not only lead to inaccurate subsequent charging amounts, but may also affect the normal operation of the device due to the accumulation of explosives, thereby easily reducing the device's effectiveness and operational safety.

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0019] According to an embodiment of the present invention, a medium-deep hole blasting charging device is provided.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a medium-deep hole blasting charging device according to an embodiment of the present invention includes a charging box 1. A motor 10 is fixedly installed at the middle position of the top surface of the charging box 1, and a reciprocating screw 11 is fixedly connected to the output end of the motor 10. A moving block 3 is installed on the reciprocating screw 11, and fixed blocks 4 are fixedly connected to both sides of the moving block 3. A scraper frame 5 is fixedly connected to one end of the fixed block 4, and brush bristles 12 are fixedly installed on the outer surface of the scraper frame 5. A discharge port is opened through the bottom surface of the charging box 1, and a sealing plate 6 is inserted through the discharge port. Push plates 15 are fixedly connected to both sides of the sealing plate 6 below the charging box 1. Electric push rods 13 are fixedly installed on both sides of the charging box 1, and the output end of the electric push rods 13 is fixedly connected to the push plates 15. The device is used to charge powdered explosives. The explosive is loaded into the explosive box 1 through the loading port 2. Then, the lifting ring 16 on the protective shell 9 is fixedly connected to the external lifting equipment. With the use of the external lifting equipment, the explosive box 1 can be transported into the medium-deep hole. The motor 10 on the top surface of the explosive box 1 is started, and the motor 10 drives the reciprocating screw 11 to rotate. The moving block 3 on the reciprocating screw 11 is limited by the use of the limiting rod 17, so that it can move up and down on the reciprocating screw 11. While the moving block 3 moves on the reciprocating screw 11, it drives the scraper frame 5 at one end of the fixed block 4 to move along the inner wall of the explosive box 1. The brush bristles 12 on the outer surface of the scraper frame 5 can be used to clean the explosive on the inner wall of the explosive box 1 to prevent it from remaining on the inner wall of the explosive box 1 for subsequent use.

[0021] Please see Figure 1 and Figure 3 Limiting rods 17 are provided on both sides of the lower surface of the top of the medicine box 1, through the moving block 3. The moving block 3 is slidably connected to the limiting rods 17. The use of the limiting rods 17 can limit the moving block 3, thereby maintaining the normal up and down reciprocating movement of the moving block 3 on the reciprocating screw 11.

[0022] Please see Figure 1 and Figure 3The scraper frame 5 and the medicine box 1 are circular structures. The diameter of the scraper frame 5 is smaller than the diameter of the medicine box 1. The bristles 12 abut against the inner wall of the medicine box 1. The inner wall of the medicine box 1 can be cleaned by using the bristles 12 on the outer surface of the scraper frame 5, which facilitates the cleaning of the inner wall of the medicine box 1 and ensures its normal use in the future.

[0023] Please see Figure 1 and Figure 2 The top surface of the explosive loading box 1 is fixedly connected to the loading port 2 on one side of the motor 10. Explosives can be loaded into the explosive loading box 1 through the loading port 2.

[0024] Please see Figure 1 and Figure 2 The top surface of the medicine box 1 is fixedly connected to the outer side of the motor 10 with a protective shell 9, and a lifting ring 16 is fixedly installed at the middle position of the top surface of the protective shell 9. The motor 10 can be protected by the use of the protective shell 9.

[0025] Please see Figure 1 and Figure 2 A heat dissipation vent is provided on one side surface of the protective shell 9, and a wire passage hole is provided above the heat dissipation vent. The heat dissipation vent can maintain the normal heat dissipation of the motor 10, and the wire passage hole can connect the power cord on the motor 10 to an external power source.

[0026] Please see Figure 1 and Figure 4 The sealing plate 6 has a conical structure and matches the discharge port. The bottom upper surface of the explosive box 1 is inclined with guide plates 14 on both sides. The sealing plate 6 has a conical structure. When used in conjunction with the guide plates 14 on both sides of the bottom upper surface of the explosive box 1, the explosive can be guided to prevent it from remaining at the bottom of the explosive box 1, thus facilitating the discharge of the explosive.

[0027] Please see Figure 1 and Figure 4 Positioning blocks 7 are fixedly connected to both sides of the top surface of the sealing plate 6, and one end of the positioning block 7 extends into the interior of the positioning groove 8 opened on both sides of the bottom surface of the medicine box 1. The positioning block 7 and the positioning groove 8 are circular structures, and the diameter of the positioning block 7 is smaller than the diameter of the positioning groove 8. The positioning block 7 and the positioning groove 8 are movably inserted into each other. The use of the positioning block 7 and the positioning groove 8 can limit the sealing plate 6, thereby maintaining the stability of the sealing plate 6 on the medicine box 1 and sealing the discharge port.

[0028] The control switch control circuit can be implemented by simple programming by those skilled in the art. It is common knowledge in the field. Since it is only used and not modified, the control method and circuit connection will not be described in detail.

[0029] Working principle: Powdered explosives are loaded into the charging box 1 through the charging port 2. The lifting ring 16 on the protective shell 9 is then fixedly connected to the external lifting equipment. Using the external lifting equipment, the charging box 1 can be transported into the medium-deep hole. By starting the motor 10 on the top surface of the charging box 1, the motor 10 drives the reciprocating screw 11 to rotate. The use of the limiting rod 17 limits the movement of the moving block 3 on the reciprocating screw 11, allowing it to move up and down on the reciprocating screw 11. While the moving block 3 moves on the reciprocating screw 11, it also drives the scraper frame 5 at one end of the fixed block 4 to move along the inner wall of the charging box 1. By using the brush bristles 12 on the outer surface of the scraper frame 5, the explosives on the inner wall of the charge box 1 can be cleaned to prevent them from remaining on the inner wall of the charge box 1, making it convenient for subsequent use. When the charge box 1 reaches the designated position, the electric push rod 13 is activated, and the electric push rod 13 drives the push plate 15 to move down, so that the sealing plate 6 is away from the discharge port on the bottom surface of the charge box 1, and the explosives can be discharged from the charge box 1. The sealing plate 6 has a conical structure, which, together with the guide plates 14 on both sides of the bottom upper surface of the charge box 1, can guide the explosives to prevent them from remaining at the bottom of the charge box 1, thus facilitating the discharge of the explosives.
