At this time, the bottom opening of the charge loading groove is no longer blocked, and the explosive in the charge loading groove can be discharged. Whether it is a fluid explosive or an explosive in the form of a charge cluster can be discharged, and the charge loading groove is vertically through, effectively reducing the residual explosive inside the charge loading box.

[0004] However, the transmission mechanism of the above-mentioned blasting charge loading device controls the opening and closing of the bottom plate by pulling a rope.

[0027] During use, rotating the rotating rod 16 can drive the threaded rod 18 to rotate inside the blasting charge outer casing 1 under the action of the limiting block 17. Through the engagement of the thread of the threaded rod 18 and the tooth portion of the gear 19, the gear 19 is driven to rotate, which facilitates driving the bottom plate 15 to rotate. Controlling the rotation direction of the rotating rod 16 can control the opening and closing of the bottom plate 15, avoiding the breakage of the rope due to the friction of the rock when using a rope to control the switch, thereby affecting the opening and closing of the bottom plate 15 and making the blasting charge device unusable, affecting the progress efficiency of the project.

[0028] Embodiment 2; On the basis of Embodiment 1, a pushing and pulling member 3 for facilitating charging and feeding the explosive is provided to send the explosive to the positioning place. A cover plate 2 is installed on the top of the blasting charge outer casing 1, a pushing and pulling member 3 is installed through the center of the cover plate 2, a hole groove 4 is opened on the top of the cover plate 2, and the top of the rotating rod 16 penetrates through the inside of the hole groove 4;

[0029] During use, the explosive is placed inside the blasting charge housing 1, the cover plate 2 is covered, and the explosive is pushed into the positioning point through the pushing and pulling member 3. At the same time, the pushing and pulling member 3 scrapes off the residual explosive powder adhered to the inner wall of the blasting charge housing 1 through the bottom, avoiding insufficient explosive dosage and resulting in poor blasting effects, which may affect the progress of the project.

[0030] Embodiment 3; on the basis of Embodiment 2, an upper fixing plate 5 is provided to facilitate the disassembly and installation of the cover plate 2, saving the use time of the blasting charge device. The bottom of the side wall of the cover plate 2 is provided with an upper fixing plate 5, and the top of the side wall of the blasting charge housing 1 is provided with a lower fixing plate 6. A groove 7 is formed inside the upper fixing plate 5, and a spring 8 is installed inside the groove 7. The spring 8 provides an upward pulling force to the movable latch 9.

[0031] During use, the movable latch 9 passes through the inside of the lower fixing plate 6, and the clamping plate 11 is pulled so that the clamping plate 11 passes through the bottom of the lower fixing plate 6. After moving in the moving groove 12 through the action of the moving groove 12 and the fixing rod 10, the clamping plate 11 can be rotated to pull the movable latch 9 through the spring 8 so that the rotated clamping plate 11 can be fixed below the lower fixing plate 6. After the upper fixing plate 5 and the lower fixing plate 6 are clamped, it is convenient to fix the cover plate 2 on the top of the blasting charge housing 1. At the same time, when the clamping plate 11 is rotated back to its original position, it is convenient to disassemble the upper fixing plate 5 and the lower fixing plate 6 and remove the cover plate 2.

[0032] Working principle: In actual use, place the explosive inside the blasting charge housing 1, cover the cover plate 2, the movable latch 9 passes through the inside of the lower fixing plate 6, pull the clamping plate 11 so that the clamping plate 11 passes through the bottom of the lower fixing plate 6, and it can move in the moving groove 12 through the action of the moving groove 12 and the fixing rod 10. After that, it can be rotated to pull the movable latch 9 through the spring 8 so that the rotated clamping plate 11 can be fixed below the lower fixing plate 6. After clamping the upper fixing plate 5 and the lower fixing plate 6, it is convenient to fix the cover plate 2 on the top of the blasting charge housing 1. Push the explosive into the positioning point through the pushing and pulling member 3. Rotate the rotating rod 16, and under the action of the limiting block 17, it can drive the threaded rod 18 to rotate inside the blasting charge housing 1. Through the engagement of the thread of the threaded rod 18 and the teeth of the gear 19, drive the gear 19 to rotate, which is convenient to drive the bottom plate 15 to rotate. Controlling the rotation direction of the rotating rod 16 can control the opening and closing of the bottom plate 15. At the same time, the pushing and pulling member 3 scrapes off the residual explosive powder adhering to the inner wall of the blasting charge housing 1 from the bottom, avoiding the problem that the blasting effect is not good due to insufficient explosive dosage. When it needs to be used again after use, when turning the clamping plate 11 back to its original position, it is convenient to disassemble the upper fixing plate 5 and the lower fixing plate 6, and it is easy to remove the cover plate 2. This avoids the problem that when using a rope to control the switch, the rope is worn by the rock and breaks, thereby affecting the opening and closing of the bottom plate 15 and making the blasting charge device unusable, which affects the progress efficiency of the project.
