[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0025] Embodiment: This embodiment aims to provide a charging device for open-pit mine blasting that is easy to seal and isolate. Its main function is to isolate and place the charging tools, eliminate factors that cause friction and collision between the charging tools, and eliminate potential safety hazards.

[0026] Reference Figure 1 and Figure 3 , including: a storage box 1 and a storage tray 5, both of which are round, a charging hole 2 is opened in the center of the top of the storage box 1, the charging hole 2 is used to pass the medicine, so that the hole diameter of the charging hole 2 is not less than the medicine to be loaded, the entrance of the charging hole 2 is expanded outward, so that the staff can quickly align the medicine with the charging hole 2, and a quick-plug rubber sealing plug 7 is inserted in the charging hole 2, and a pull ring is provided on the top of the sealing plug 7 to assist the staff to seal The plug 7 is quickly removed from the charging hole 2; a support 3 is provided at the bottom of the storage box 1, which ensures that the storage box 1 is placed horizontally on the ground or in the cargo box of a transport vehicle, and a carrying rod 4 is welded and fixed to the middle of the rear side of the storage box 1. The upper end of the carrying rod 4 is bent 90° toward the storage box 1 and is located directly above the storage box 1, that is, the bent portion of the carrying rod 4 corresponds to the charging hole 2, thereby facilitating the staff to lift the storage box 1 upwards through the bent portion of the carrying rod 4.

[0027] Reference Figure 3The storage tray 5 is rotatably arranged in the box cavity of the storage box 1, and the storage tray 5 is ensured to be coaxially arranged with the storage box 1. The storage tray 5 is provided with a storage groove 6 in the radial direction, and a plurality of the storage grooves 6 are arranged along the circumferential direction of the storage tray 5. When the storage tray 5 is rotated, the storage groove 6 will pass through the charging hole 2. During this period, the storage groove 6 will correspond to the charging hole 2. At this time, the medicine in the charging hole 2 will automatically fall into the storage groove 6 under this condition. It should be understood that the larger the diameter of the storage tray 5, the more corresponding storage grooves 6 will be opened. During actual processing, the processing size of the storage tray 5 should be determined according to needs; the storage groove 6 can be made to pass through the charging hole 2 by rotating the storage tray 5, and the depth of the storage groove 6 does not exceed the length of the medicine to be loaded. The purpose is to improve the convenience and smoothness of placing the medicine, so that there is no need to wait until the storage groove 6 completely corresponds to the charging hole 2 before placing the medicine in the charging hole 2.

[0028] Reference Figure 3 Rollers 9 are distributed on the cavity wall of the storage box 1 facing the storage groove 6, and the axial direction of the rollers 9 is consistent with the axial direction of the storage disk 5. A rolling surface is formed on the cavity wall of the storage box 1 by multiple rollers 9. The function of the rolling surface is to prevent the end surface of the medicine tool exposed in the storage groove 6 from generating a large friction with the cavity wall of the storage box 1 during the rotation of the storage disk 5, thereby adversely affecting the explosives and ensuring the stability of the explosives. The distance from the rollers 9 to the bottom of the corresponding storage groove 6 is consistent with the length of the medicine tool to be loaded. The purpose of this setting is to prevent the medicine tool from shaking axially in the storage groove 6, thereby further ensuring the stability of the explosives.

[0029] Reference Figure 1 , Figure 2 and Figure 3 Corresponding to the carrying rod 4, a crank 8 is provided on the other side of the storage box 1, that is, the front side of the storage box 1. The crank 8 is Z-shaped in appearance. One end of the crank 8 faces the middle of the storage box 1 and passes through the box wall of the storage box 1 and is fixed to the middle of the storage tray 5. The crank 8 and the storage box 1 can be connected by a bearing, thereby reducing the friction resistance generated by turning the crank 8 and reducing the labor intensity of the staff.

[0030] In the present embodiment, the distance from the top of the storage box 1 to the bent portion of the carrying rod 4 is not less than the length of the medicine to be loaded. Specifically, when the medicine needs to be taken out of the storage box 1, the storage box 1 needs to be inverted so that the entrance of the charging hole 2 faces downward. At this time, the bent portion of the carrying rod 4 serves as a temporary component to support the storage box 1, so that the medicine in the storage slot 6 corresponding to the charging hole 2 will automatically fall out. If the distance from the bent portion of the carrying rod 4 to the storage box 1 is less than the length of the medicine, it will prevent the medicine from leaving the storage slot 6 and affect the speed of taking out the medicine. Therefore, this setting further improves the use effect of the device and makes the use of the device more convenient.

[0031] When actually using, first place the device horizontally on the ground to ensure the stable placement of the storage box 1, and then the staff will directly insert the medicine into the charging hole 2. At this time, the medicine will be retained in the charging hole 2 because there is no storage groove 6 corresponding to the charging hole 2. Next, the staff needs to rotate the storage plate 5 by the crank 8 to change the position of the storage groove 6 on its side. When there is a storage groove 6 corresponding to the charging hole 2, the medicine will directly fall into the storage groove 6. At this time, there is no need to continue rotating the storage plate 5. Instead, insert a new medicine into the charging hole 2 and then By rotating the storage tray 5 and repeating this operation, it can be ensured that each storage slot 6 can be loaded with a medicine tool to avoid missing medicine tools, and finally the charging hole 2 can be sealed with the sealing plug 7; when the device is transported to a designated open-pit mine and medicine tools need to be taken out to perform blasting operations, the device is first turned upside down on the ground, that is, the bent part of the carrying rod 4 is facing downward in contact with the ground, and the storage box 1 is facing upward, and then the sealing plug 7 is removed and the storage tray 5 is slowly rotated, and the medicine tools will fall out from the charging hole 2 one by one as the storage tray 5 rotates.

[0032] This embodiment eliminates the safety hazard of traditional explosives boxes for storing medicinal tools by isolating and placing them to prevent friction and collision between them, thereby providing protection for moving vehicles and accompanying personnel on the vehicles. On this basis, the device is easy to carry and simple to use, which brings great convenience to the operators. At the same time, it has good sealing effect and excellent moisture-proof effect, and ensures that the explosive is not affected by external factors through the double barrier of medicinal tools and storage box 1, thereby ensuring the stability of the explosives.

[0033] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
