The stretching cylinder 1, the first connecting cylinder 2, the medicine storage cylinder 3 and the second connecting cylinder 5 in the embodiment are all cylindrical and are communicated in sequence, wherein:

one end of the extending cylinder 1 departing from the first connecting cylinder 2 is closed;

the cylinder diameter of the first connecting cylinder 2 is larger than that of the extending cylinder 1, and an external thread 21 is formed on the outer wall of the first connecting cylinder 2;

the diameter of the medicine storage barrel 3 is larger than that of the first connecting barrel 2;

the sealing gland 4 is fixedly connected with one end, away from the extending cylinder 1, of the explosive storage cylinder 3, the sealing gland 4, the explosive storage cylinder 3, the first connecting cylinder 2 and the extending cylinder 1 are encircled to form a cavity for storing explosives, a detonating hole 41, a detonator hole 42 and two convex blocks 43 are formed in the sealing gland 4, and the detonating hole 41 and the detonator hole 42 are both sunken towards the inner direction of the explosive storage cylinder 3; the two convex blocks 43 are positioned on the surface of the sealing gland 4 which deviates from the surface extending into the cylinder 1, and the convex blocks 43 increase the wiring space of the detonator in series connection, so that the implementation is more convenient. The number of the convex blocks 43 is not limited to two in the present embodiment, and may be adjusted to be plural, for example, three or five, according to actual conditions.

The inner cylinder diameter of the second connecting cylinder 5 is the same as the outer cylinder diameter of the first connecting cylinder 2, an internal thread 52 is formed on the inner wall of the second connecting cylinder 5, the internal thread 52 on the second connecting cylinder 5 is matched with the internal thread 21 on the first connecting cylinder 2, and a detonator lead hole 51 is further formed in the second connecting cylinder 5.

Further, the penetration cylinder 1, the first connection cylinder 2, the storage cylinder 3, the gland 4 and the second connection cylinder 5 in the present embodiment are made of polyethylene, and the axes of the penetration cylinder 1, the first connection cylinder 2, the storage cylinder 3, the detonation hole 41 and the second connection cylinder 5 coincide. The axes are overlapped, so that the seismic charge shell is more convenient to machine and form and is more attractive. It should be noted that the material of the seismic charge casing provided by the present invention is not limited to the polyethylene in this embodiment, and when the material is actually implemented, the material can be replaced by a material that more meets the actual requirement according to the actual situation.
