DETAILED DESCRIPTION

[0026] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0027] Example 1

[0028] Please refer to Figure 1 , Embodiment 1 of the utility model provides a detonating bomb casing 1, comprising a shell 11 and a plurality of support rods 12;

[0029] Each of the support rods 12 is connected to the outer wall of the outer shell 11 and is tilted outwardly relative to the central axis of the outer shell 11. The maximum distance between each of the support rods 12 and the central axis of the outer shell 11 is not less than the inner diameter of the blasthole. Preferably, each of the support rods 12 is fixedly connected to the outer wall of the outer shell 11. The maximum distance between each of the support rods 12 and the central axis of the outer shell 11 is slightly larger than the inner diameter of the blasthole. A plastic deformation portion is formed at one end of each of the support rods 12 away from the outer shell 11. The plastic deformation portion is made of plastic material (such as plastic) and can undergo plastic deformation.

[0030] Please refer to Figure 1 and Figure 7When in use, Example 1 is loaded with the detonating bomb shell 1 into the outlet tube 41 of the tube feeder 4, then the outlet of the outlet tube 41 is aligned with the blast hole on the rock wall, then the charging tube is inserted into the inlet of the tube feeder 4, the tube feeder 4 is opened, and the charging tube enters the outlet tube 41 from the outlet of the tube feeder 4. When the charging tube contacts the detonating bomb shell 1 in the outlet tube 41, it will push the detonating bomb shell 1 to move forward and push the detonating bomb shell 1 into the blast hole to a certain depth. Then the charging tube is rolled up by the tube feeder 4, so that the charging tube is slowly pulled out of the blast hole. While pulling out the charging tube, the explosive is transported into the charging tube by the pumping device. Therefore, while pulling out the charging tube, the explosive will gradually fill the blast hole, and the explosive can be detonated later by starting the detonating bomb installed in the detonating bomb shell 1.

[0031] In Example 1, during the movement of the explosive bomb shell 1 in the blast hole, since the maximum distance between each support rod 12 and the central axis of the shell 11 is not less than the inner diameter of the blast hole, each support rod 12 will be in close contact with the inner wall of the blast hole, and the plastic deformation portion of the support rod 12 will be slightly deformed. The friction between the support rod 12 and the inner wall of the blast hole is relatively large, and even if the blast hole is tilted upward, the explosive bomb shell 1 is not easy to slide down. In addition, by providing multiple support rods 12 to support the shell 11, the shell 11 can be kept in the center position in the blast hole, and the shell 11 will not rub against the inner wall of the blast hole, so it is not easy to wear, and the explosive bomb inside it can be well protected. The utility model can improve the stability of the explosive bomb shell 1 during the movement of the blast hole.

[0032] To facilitate the detonation of explosives, please refer to Figure 1 In a preferred embodiment, the housing 11 is a plastic housing.

[0033] In order to facilitate the insertion of the shell 11 into the explosive in the blast hole, please refer to Figure 1 In a preferred embodiment, a tapered portion 111 is formed at the front end of the shell 11, thereby increasing the contact area between the shell 11 and the explosive and improving the detonation effect of the detonating bomb.

[0034] Example 2

[0035] Please refer to Figure 2-Figure 7 , Embodiment 2 of the utility model provides a detonating bomb casing 1, comprising a shell 11, a plurality of support rods 12 and a plurality of elastic members 13;

[0037] The number of the elastic members 13 is equal to and corresponds to the number of the support rods 12 , one end of each of the elastic members 13 is fixedly connected to the outer wall of the housing 11 , and the other end of each of the elastic members 13 is fixedly connected to the corresponding support rod 12 .

[0038] When in use, Example 2 is to load the explosive bomb shell 1 into the outlet tube 41 of the tube feeder 4, then align the outlet of the outlet tube 41 with the blast hole on the rock wall, then insert the charging tube into the inlet of the tube feeder 4, open the tube feeder 4, and allow the charging tube to enter the outlet tube 41 from the outlet of the tube feeder 4. When the charging tube contacts the explosive bomb shell 1 in the outlet tube 41, it will push the explosive bomb shell 1 forward and push the explosive bomb shell 1 into the blast hole to a certain depth. Then, the charging tube is rolled up by the tube feeder 4 and slowly pulled out of the blast hole. While pulling out the charging tube, the explosive is transported into the charging tube by the pumping device. Therefore, while pulling out the charging tube, the explosive will gradually fill the blast hole, and the explosive can be detonated later by starting the explosive installed in the explosive bomb shell 1.

[0039] In Example 2, when the explosive bomb shell 1 moves in the blast hole, each support rod 12 will be in close contact with the inner wall of the blast hole under the thrust of the elastic member 13. The friction between the support rod 12 and the inner wall of the blast hole is large. Even if the blast hole is tilted upward, the explosive bomb shell 1 is not easy to slide down. In addition, by providing multiple support rods 12 to support the shell 11, the shell 11 can be kept in the center position in the blast hole. The shell 11 will not rub against the inner wall of the blast hole, so it is not easy to wear, and the explosive bomb inside can be well protected. In addition, when the explosive bomb shell 1 encounters a step surface during the movement of the blast hole, the elastic member 13 can be contracted to cross the step surface to prevent the explosive bomb shell 1 from being stuck in the blast hole and unable to go deeper. The utility model can improve the stability of the explosive bomb shell 1 during the movement of the blast hole.

Even if the blast hole is tilted upward, the explosive bomb shell 1 is not easy to slide down. In addition, by providing multiple support rods 12 to support the shell 11, the shell 11 can be kept in the center position in the blast hole. The shell 11 will not rub against the inner wall of the blast hole, so it is not easy to wear, and the explosive bomb inside can be well protected; in addition, when the explosive bomb shell 1 encounters a step surface during the movement of the blast hole, the elastic member 13 can be contracted to cross the step surface to prevent the explosive bomb shell 1 from being stuck in the blast hole and unable to go deeper.
