DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0025] Please refer to Figures 1-5

[0026] Embodiment 1

[0027] The mounting device of the detonator for mine blasting comprises a lining plate 10, downwardly extending brackets 11 are arranged on both sides of the lining plate 10, and the two groups of brackets 11 can support the lining plate 10 on the surface of earth and stone.

[0028] Preferably, the bottoms of the two groups of brackets 11 are respectively provided with a plurality of insertion columns 111, and the stability of the overall external structure is further improved by the insertion columns 111 in use.

[0029] The storage mechanism 20 comprises a frame 21 and movable assemblies arranged on the frame 21, the movable assemblies are preferably two groups, and the movable assemblies comprise transverse grooves 22, straight plates 23 and supporting plates 24, the transverse grooves 22 are arranged on the frame 21, the straight plates 23 are fixedly connected with the frame 21, and the supporting plates 24 are slidably connected with the transverse grooves 22 through sliding blocks.

[0030] The transverse groove 22 and the sliding block are in a T-shaped structure in sliding fit, the bottom end of the supporting plate 24 is connected with a pad 241, a vertical groove 231 for the supporting plate 24 to slide transversely is arranged on the straight plate 23, the pad 241 is used for supporting the detonator, and a sharp end 242 is arranged on the bottom of the pad 241, so that the effect of pushing the residual rocks in the blast hole downward is improved.

[0031] The abutting rod 30 is movably arranged on the frame 21, the abutting rod 30 vertically extends downward and is connected with a gland 31, and the inner side of the gland 31 is preferably provided with a rubber layer, and the gland 31 can be buckled on the top of the detonator.

[0032] The detonator can be vertically placed on the pad 241, and the top of the detonator is limited by the gland 31, the lining plate 10 is provided with an extension source 40, the movable end of the extension source 40 is connected with the frame 21, and the extension source 40 is used for driving the frame 21 to vertically ascend and descend, the extension source 40 is preferably an electric cylinder, and the movable rod of the extension source 40 is controlled to be retracted, so that the movable assemblies and the detonator placed thereon can enter into the blast hole.

[0033] Specifically, the bracket 11 is located inside the straight plate 23 by sliding through the vertical groove 231, and the top of the detonator is vertically placed on the cushion block 241 and limited by the gland 31. The two groups of brackets 11 can be supported on the earth surface to support the lining plate 10, so that the detonator is aligned with the blast hole. The telescopic source 40 drives the frame 21 to move downward, so that the straight plate 23 and the supporting plate 24 drive the detonator to enter the blast hole. During this process, the abutting rod 30 moves downward under the gravity, so that the gland 31 is always buckled on the top of the detonator. When the cushion block 241 moves downward along the blast hole, the residual debris in the blast hole can be pushed downward, so that the cannon barrel can smoothly enter the inside of the blast hole. Then, the push plate is moved to the vertical groove 231 outside the blast hole, so that the cushion block 241 is moved away from the bottom of the cannon barrel. Then, the telescopic source 40 drives the frame 21 to move upward, so that the straight plate 23 and the supporting plate 24 are away from the blast hole. At this time, the abutting rod 30 still moves downward relative to the frame 21 under the gravity, so that the gland 31 is always buckled on the top of the detonator, preventing the detonator from being taken out. Finally, the abutting rod 30 is pulled upward to drive the gland 31 to be separated from the blast hole, so that the detonator is smoothly and non-deformably installed, avoiding the situation that the residual debris in the blast hole is blocked and difficult to install.

[0034] When the cushion block 241 is moved away from the bottom of the cannon barrel, the abutting rod 30 can be pulled upward by a distance, so that the cushion block 241 is smoothly moved away. It should be noted that the radius of the blast hole is greater than the distance between the outer wall of the straight plate 23 and the center of the gland 31.

[0035] Embodiment 2

[0036] A detonator mounting device for mine blasting, based on the device of embodiment 1, the top of the lining plate 10 is fixedly connected with a cover plate 12, the cover plate 12 and the lining plate 10 form a isolation area in which the telescopic source 40 is accommodated, and the cover plate 12 extends longitudinally. On the one hand, the mounting device can be taken by the cover plate 12, and on the other hand, the telescopic source 40 is protected.

[0037] The horizontal groove 22 is provided with a spring 221, which is used to push the supporting plate 24 to slide through the vertical groove 231, that is, the supporting plate 24 can be inside the straight plate 23 under the elastic force of the spring 221.

[0038] The sliding block is provided with a pull rod 244, which can drive the supporting plate 24 to slide into the vertical groove 231 by being compressed by the spring 221. The inner end of the cushion block 241 is provided with a plurality of rolling balls 243 which can contact the outer wall of the detonator. After the detonator is installed, the supporting plate 24 can be slid into the vertical groove 231 by pushing the pull rod 244 to drive the cushion plate to move away from the bottom of the detonator. During the process that the frame 21 moves upward to drive the straight plate 23 and the supporting plate 24 to move away from the blast hole, the plurality of rolling balls 243 at the inner end of the cushion block 241 can rollingly contact the outer wall of the detonator, effectively reducing the frictional resistance generated by the movement of the cushion block 241 and the outer wall of the detonator.
