Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of the utility model protection.

[0028] Please refer to Figures 1-7 , the utility model provides a long drilling hole blasting charging device, including head rod 1, head rod 1 is set up with placement cabin 12, head rod 1 bolt connection has connecting rod 2, connecting rod 2 inside is equipped with connecting steel cable 21, and the both ends of connecting steel cable 21 are fixedly connected with snap ring 22, and connecting rod 2 is screw connected with tail rod 3, and head rod 1 is equipped with charging mechanism;

[0029] In the embodiment of the utility model, in order to be able to place explosive in the hole, specifically, the charging mechanism includes cover body 11, cover body 11 is hinged with the outer wall of head rod 1, the outer wall of cover body 11 is fixedly connected with protruding block 111, hinged plate 13 is hinged with the inner wall of placing cabin 12, the outer wall of hinged plate 13 is hinged with hinged rod 14, the end of hinged rod 14 away from hinged plate 13 is hinged with sliding block 15, sliding block 15 is elastically connected with the inner wall of head rod 1 through spring, the outer wall of sliding block 15 is fixedly connected with steel cable one 151, the tail end of steel cable one 151 is fixedly provided with ring one 152, one end of rod body 16 is fixedly connected with push plate 161, the other end of rod body 16 is fixedly connected with sliding block 15, push plate 161 is elastically connected with the inner wall of head rod 1 through spring, push plate 161 is provided with through slot 162, through slot 162 is slidably connected with clamping rod 163, clamping rod 163 is penetrated by guide rod 164 and is slidably connected with guide rod 164, guide rod 164 is fixedly connected with the inner wall of head rod 1, clamping rod 163 is elastically connected with the inner wall of head rod 1 through spring, clamping rod 163 is provided with two groups, and the two groups of clamping rods 163 are symmetrically distributed on the both sides of the inner wall of head rod 1;

[0030] Further, the tail rod 3 is provided with steel cable two 31 inside, one end of steel cable two 31 is fixedly connected with ring two 32, the other end of steel cable two 31 is fixedly connected with sliding rod 33, sliding rod 33 penetrates tail rod 3 and is slidably connected with tail rod 3, sliding rod 33 is provided with clamping groove 34, and the outer wall of tail rod 3 is provided with elastic rod 35;

[0031] In the utility model, in use, first explosive is placed in placing cabin 12, then cover body 11 is closed, when cover body 11 is closed, protruding block 111 fixedly connected with the outer wall of cover body 11 will extrude clamping rod 163, as shown in the figure, Figure 4 As shown, through slot 162 is composed of straight slot and inclined slot, when protruding block 111 extrudes clamping rod 163, clamping rod 163 slides in straight slot at this time, when protruding block 111 and clamping rod 163 are separated, clamping rod 163 will return to the original position under the elastic force of spring at this time, thereby limiting protruding block 111, reaching the purpose of locking cover body 11, preventing explosive from sliding out of the inner wall of placing cabin 12 in the process of sending explosive, simultaneously, through the design of placing cabin 12, explosive can be protected, preventing the stone inside the hole from scratching the outer wall of explosive;

[0032] Subsequently, based on the depth of the hole, multiple sets of connecting rods 2 and connecting cables 21 are added, and the retaining rings 22 at both ends of the connecting cables 21 are respectively engaged with ring 152 and ring 32. Then, the head rod 1 is extended into the hole. When the head rod 1 reaches the end of the hole, the sliding rod 33 is pulled. At this time, through the transmission of the second steel cable 31 and the connecting cables 21, the first steel cable 151 pulls the sliding block 15. When the sliding block 15 is pulled, the hinge rod 14 applies a force to the hinge plate 13, causing the hinge plate 13 to tilt at a certain angle around the hinge point. At the same time, through the transmission of the rod body 16, the push plate 161 slides. When the push plate 161 slides, the inclined groove on the through groove 162 applies a force to the retaining rod 163, causing the retaining rod 163 to move towards both sides of the inner wall of the head rod 1, thereby releasing the limiting position of the cover 11. Figure 7 As shown, the elastic rod 35 is in a compressed state. When the sliding rod 33 moves a certain distance, the slot 34 will coincide with the elastic rod 35. At this time, the elastic rod 35 will spring into the slot 34 under the action of the spring force, thereby completing the limiting of the sliding block 15. Then, the head rod 1 is slowly pulled out. During this process, since the hinge plate 13 is in an inclined state and the cover 11 is in an unlocked state, the explosive in the hinge plate 13 will slowly slide from the hinge plate 13 into the outer wall of the hole, thereby achieving the purpose of loading the explosive. When the head rod 1 is completely pulled out, the elastic rod 35 is pulled to contact the limiting of the sliding block 15. Then, the sliding block 15 and the push plate 161 return to their original positions under the action of the spring force.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
