[0002] In blasting engineering, the use of detonators is crucial to ensure the safety and efficiency of blasting operations. Its main function is to provide sufficient energy to initiate the explosive reaction of the explosive. Detonators are sensitive explosives that can burn rapidly and transform into detonation under the action of weak external excitation energy such as mechanical, thermal, electrical, and optical. Therefore, safety must be paid attention to when using detonators. Existing detonators are usually used in the form of explosive bags, which makes it inconvenient when placing explosives in some special locations and spaces, and the preparation operations before placement are also cumbersome, affecting the efficiency of use. To this end, we propose a detonator device for blasting. Summary of the invention

[0021] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 As shown, the detonating charge device for blasting includes a housing 1. A plurality of "T"-shaped slots 2 are evenly opened on the inner surface of the housing 1. A plurality of supplementary cylinders 3 are inserted into the housing 1 through the inner surface of the slots 2. One side of the outer surface of the supplementary cylinder 3 is provided with an insert block 4 in a "T"-shaped convex shape. The insert block 4 is inserted into the slot 2. In the middle of the inner bottom surface of the housing 1, a filling cylinder 5 is fixedly provided. A plurality of connecting pieces are fixedly provided on the outer surface of the filling cylinder 5. The outer surface of the filling cylinder 5 is connected to the inner surface of the housing 1 through the connecting pieces. A plurality of conduction ports 6 are opened on the outer surfaces of both the supplementary cylinder 3 and the filling cylinder 5;

[0023] On both sides of the middle of the lower surface of the housing cover 7, connecting blocks 17 are provided. The length dimension of the connecting block 17 is equal to the interval dimension between the inner surface of the housing 1 and the outer surface of the filling cylinder 5. The upper surface opening of the housing 1 is covered with the housing cover 7. A plurality of openings are evenly opened on the outer side of the upper surface of the housing cover 7. A first sealing plug 8 is inserted and installed through the inner surface of the opening of the housing cover 7. A plurality of detonating cords 9 are inserted through the middle of the upper surface of the first sealing plug 8. One end of the detonating cord 9 extends into the housing 1;

[0024] A sealing plate 16 is fixedly provided in the middle of the lower surface of the housing cover 7. An opening is commonly opened on the middle of the upper surfaces of the housing cover 7 and the sealing plate 16. A second sealing plug 10 is inserted and installed through the inner surface of the opening of the housing cover 7. A limit socket 11 is opened in the middle of the lower surface of the sealing plate 16. A detonating fuse 12 is inserted and installed through the inner surface of the limit socket 11. The end of the detonating fuse 12 inserted into the limit socket 11 is provided with a detonator pin 13. The other end of the detonator pin 13 penetrates through the second sealing plug 10 and extends outwards. A clamping frame 14 is sleeved and installed on the outer surface of the detonating fuse 12. One end of the clamping frame 14 is butt-jointed and installed with the limit socket 11. The other end of the clamping frame 14 is provided with a piercing head 15. Both the clamping frame 14 and the piercing head 15 are made of wooden structures.

[0025] When the utility model is in use, first, the prepared explosive package can be filled into the filling tube 5 arranged in the shell body 1, so that the filling tube 5 can be used to clamp and fix the explosive package. If there is a problem of insufficient amount of explosive package during specific blasting, the additional explosive package can be filled into the supplementary tube 3 according to the direction of strengthening the blasting effect, and the supplementary tube 3 is inserted into the corresponding direction position in the shell body 1. In this case, it is convenient to adjust the amount of explosive package. At the same time, there are intervals between the explosive packages to avoid safety hazards caused by their contact. In the detonation state, the detonation energy can be integrated and conducted through the conduction port 6 opened on the outer surface of the supplementary tube 3 and the filling tube 5. After the explosive package is filled, the shell body 1 can be sealed with the shell cover 7. In this case, the explosive package wrapped by the shell body 1 can be used for explosive placement and detonation in various positions and spaces;

[0026] Secondly, when sealing the shell cover 7, the detonating cord 9 can be fixed through the first sealing plug 8 provided on the shell cover 7, and the detonating cap 12 can be plugged and connected with the limiting socket 11 provided on the shell cover 7, and the fixing of the detonation result can be completed by using the fixing structure, thereby avoiding the cumbersome phenomenon of manual operation. At the same time, since the opening positions of the first sealing plug 8 and the limiting socket 11 correspond to the insertion positions of the filling cylinder 5 and the supplementary cylinder 3 provided in the shell body 1, the detonating cap 12 and the detonating cord 9 can be respectively inserted into the corresponding filled detonating powder bag under the cover of the shell cover 7, so as to be used for detonating the detonating powder bag;

[0027] When the detonating detonator 12 is inserted into the explosive package, the explosive package can be punctured and opened with the help of the clamping frame 14 and the puncturing head 15, so that the detonating detonator 12 set in the clamping frame 14 can be inserted into the explosive package synchronously, avoiding the cumbersome operation problem of the traditional detonating detonator 12 needing to open a hole before inserting and fixing it into the explosive package;

[0028] Finally, the sealing disk 16 on the shell cover 7 is covered to the opening on the upper surface of the filling tube 5, and the connecting block 17 is embedded in the gap between the shell 1 and the filling tube 5 to complete the clamping connection between the shell cover 7 and the shell 1. In this case, the explosive package will be effectively sealed in the shell 1, which is suitable for the use of explosives placement and detonation in various positions and spaces. At the same time, the detonator pin 13 connected to the detonating cap 12 extends outward and can be connected to it using a detonating wire, thereby controlling the detonating cap 12 to operate and detonate the explosive package to complete the detonation of the explosive.
