The following is the working process that the positioning protection mechanism is used for positioning and fixing with the blast hole:
when in use, the conical positioning seat 301 is inserted into the blast hole through the external mechanical claw, at this time, the conical positioning seat 301 is positioned on the inner wall of the blast hole, the placement platform 1 can cover the blast hole, meanwhile, through the conical structure at the bottom of the fixing rod 315, the bottom of the positioning seat 1 can be inserted into the ground when the placement platform 1 covers the blast hole, thereby increasing the friction between the placement platform 1 and the ground, increasing the fixing effect when the placement platform 1 covers the blast hole, then the knob 311 is manually rotated, the rotation shaft 309 and the driving gear 310 can be driven to rotate simultaneously through the rotation of the knob 311, at this time, because the driving gear 310 and the driven gear 308 are meshed with each other, when the driving gear 310 rotates, the driven gear 308 and the connecting shaft 307 can be simultaneously rotated, when the driven gear 308 and the connecting shaft 307 rotate, the rotating disc 302 is simultaneously driven to rotate, the guide groove 303 rotates along with the rotating disc 302, and the guide groove 303 is arranged in a spiral shape, when the drill bit rotates, one end of the sliding rod 304 can be spirally faced to guide the sliding rod 304 to slide outwards, and meanwhile, the fixing plate 305 and the conical block 306 are pushed to slide outwards, so that the fixing plate 305 and the conical block 306 approach to the inner surface of the blast hole, the fixing plate 305 is abutted to the inner surface of the blast hole through the conical structure of the conical block 306, thereby increasing friction with the inner surface of the blast hole, further increasing fixing effect among the fixing plate 305, the conical block 306 and the inner surface of the blast hole, further increasing fixing effect among the conical locating seat 301 and the placing table 1 and the blast hole, further blocking the placing table 1 and locating the conical locating seat 301, enabling the blast hole to be covered before pushing rock powder sediment, preventing the rock powder sediment from entering the blast hole, avoiding reduction of the depth of the drilled blast hole and occurrence of blockage, enabling subsequent blasting operation to be smoother, meanwhile, due to the arrangement of the fixing rods 315, the fixing plates 305 and the conical blocks 306, when the placing table 1 and the conical positioning seat 301 are used, the placing table is better fixed with a blast hole, the situation that the covering effect is poor due to shaking of the placing table 1 and the conical positioning seat 301 when the rock powder sediment pushing operation is carried out later is prevented, and the covering and positioning work of the placing table 1 and the conical positioning seat 301 is more stable;
further, after the fixing plate 305 and the conical block 306 are abutted against the inner surface of the blast hole, the U-shaped connecting rod 312 can be manually pressed down, the clamping ring 313 is driven to move downwards by the U-shaped connecting rod 312, and as the inner surface of the fixing ring 314 is made of rubber, when the clamping ring 313 moves downwards, the inner surface of the fixing ring 314 is elastically deformed, so that the clamping ring 313 is abutted against the inner surface of the fixing ring 314, at the moment, the friction force between the clamping ring 313 and the fixing ring 314 is larger, thereby increasing the friction required when the knob 311 rotates, improving the fixing effect of the knob 311, preventing the knob 311 from rotating when the placing table 1 is used, and further increasing the stability of the fixing plate 305 and the conical block 306 when being abutted against the inner surface of the blast hole;
the above operation is described with reference to fig. 3 to 7.
