[0017] In order to make the above-mentioned purpose, characteristics and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model will be described in detail below. In the following description, a lot of specific details are set forth in order to fully understand the utility model. However, the utility model can be implemented in many other ways different from the description herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the following disclosed specific embodiments.

[0018] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical", "horizontal", "left", "right", and similar expressions used herein are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] like Figs. 1 to 3 As shown, an energy-concentrating device is characterized by comprising two parallel energy-concentrating cones 1, which are connected by a connecting part 5. Each energy-concentrating cone 1 is provided with a V-shaped energy-concentrating groove, and the apex of the V-shaped energy-concentrating groove of the two energy-concentrating cones 1 is arranged towards the connecting part 5.

[0021] Two shaped charge cones 1 are directly connected together through the connecting part 5 without setting an outer tube structure. In this way, during use, one end of the explosive is cut open, and then the shaped charge device is inserted into the explosive from the end, thus forming an explosive with a shaped charge device. This simplifies the loading process and reduces the amount of explosive extruded, thereby improving blasting efficiency and reducing blasting costs.

[0022] At this time, the two shaped charge cones 1 are connected by the connecting part 5, so that the two shaped charge cones 1 form a whole. The number of connecting parts 5 can be set according to actual needs. After the shaped charge device is inserted into the explosive, the relative position of the two V-shaped shaped charge grooves of the shaped charge device will not change. The apex of the V-shaped shaped charge groove faces inward, and the opening of the V-shaped shaped charge groove faces outward. Therefore, after the shaped charge device is inserted into the explosive, a shaped charge blast can be formed during the blast.

[0023] At this time, the V-shaped energy-concentrating groove is formed by the energy-concentrating cone 1. In this embodiment, the energy-concentrating cone 1 includes a first inclined surface 11 and a second inclined surface 12. The first inclined surface 11 and the second inclined surface 12 form a V-shaped energy-concentrating groove near the connecting part 5. At this time, an apex is formed at the connection between the first inclined surface 11 and the second inclined surface 12, thereby forming a V-shaped energy-concentrating groove between the first inclined surface 11 and the second inclined surface 12.

[0024] In the process of inserting the shaped charge device into the explosive, in order to keep the position between the first inclined surface 11 and the second inclined surface 12 of the shaped charge device relatively fixed, that is, the first inclined surface 11 and the second inclined surface 12 will not be deformed when inserting the explosive, in the embodiment, the outer end of the first inclined surface 11 and the second inclined surface 12 is provided with a connecting surface 13, the connecting surface 13 is a plane or a circular arc surface, the first inclined surface 11, the second inclined surface 12 and the connecting surface 13 form a hollow shaped charge cone 1. In this way, the outer end of the first inclined surface 11 and the second inclined surface 12 is supported by the connecting surface 13, and the relative position of the first inclined surface 11 and the second inclined surface 12 is not easy to change, so as to ensure the energy concentration effect during blasting, and at the same time, the explosive can also be prevented from entering the V-shaped energy concentration groove, which affects the energy concentration effect during blasting.

[0025] Because the length of the blast hole is different in use, the amount of explosive set is different, and in use, it may be necessary to splice multiple shaped charge devices into a longer length, so in the embodiment, the two ends of the shaped charge cone 1 are respectively provided with a first fixing part 2 and a second fixing part 3, and when two adjacent shaped charge devices are assembled, the first fixing part 2 of one of the shaped charge devices is fixed with the second fixing part 3 of the other shaped charge device. Under the action of the first fixing part 2 and the second fixing part 3, two shaped charge devices can be placed side by side, so that the shaped charge device is lengthened as a whole to adapt to the length requirement of different explosives, of course, at this time, the length of the shortest shaped charge device can also be set according to the length of the explosive, and it is not necessary to splice.

[0026] The first fixing part 2 and the second fixing part 3 are used to splice two shaped charge devices together, so in the embodiment, the first fixing part 2 is a fixing protrusion arranged at the end of the shaped charge cone 1, and the second fixing part 3 is a fixing groove arranged at the end of the shaped charge cone 1. The first fixing part 2 and the second fixing part 3 are arranged at the end position and are respectively a fixing protrusion and a fixing groove, so that after splicing, the overall size of the outer side of the shaped charge device will not be affected, so that during the process of inserting into the blast hole, the hole diameter of the blast hole does not need to be increased, and the use is more convenient.

[0027] Specifically, the fixed recess is a hollow part in the middle hollow part of the first inclined surface 11, the second inclined surface 12 and the connecting surface 13 of the energy-gathering cone 1, and the fixed protrusion extends from the middle hollow part, and the shape of the fixed protrusion is matched with the hollow part. The fixed recess is formed in the first inclined surface 11, the second inclined surface 12 and the connecting surface 13, so that a separate fixed recess does not need to be additionally arranged, and the fixed protrusion is a protrusion extending from the hollow part. After the fixed protrusion is clamped into the fixed recess of another energy-gathering device, the two energy-gathering devices can be spliced together. At this time, since the fixed protrusion extends from the middle hollow part, the middle hollow part of the energy-gathering cone 1 can also be sealed from the end part. Therefore, if one end of the fixed protrusion is inserted first in the process of inserting into the blast hole, the gravel and other sundries in the blast hole can be prevented from entering the V-shaped energy-gathering groove, so as to ensure the energy-gathering effect.

[0028] In the process of splicing the plurality of energy-gathering devices, in order to improve the firmness between the two energy-gathering devices after splicing, in the embodiment, the end part of the energy-gathering cover 4 is a plane or an inclined surface, and the two energy-gathering devices are attached at the plane or the inclined surface position after assembly.

[0029] Finally, in order to enable the energy-gathering device to be used in combination with the energy-gathering cover 4, in the embodiment, the end part of the energy-gathering device is provided with the energy-gathering cover 4, the side wall of the energy-gathering cover 4 is provided with a clamping groove corresponding to the energy-gathering cone 1, and the energy-gathering cone 1 of the energy-gathering device is inserted into the clamping groove. In this way, the energy-gathering cone 1 of the energy-gathering device is clamped in the clamping groove of the energy-gathering cover 4, so that the energy-gathering device and the energy-gathering cover 4 are fixed together.

[0030] The technical features of the above embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the description.

[0031] The above embodiments only express several implementation manners of the utility model, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
