Description

Technical Field

[0001] The utility model belongs to the field of storage and transportation of detonators, in particular to a detonator used for matching detonating bombs and a detonator feeding device. Background Art

[0002] Open-pit mines are usually mined using drilling and blasting techniques. The process includes drilling blastholes, filling them with powder, and placing explosive bombs. The explosive bombs are connected to detonators, and the wire at the tail of the detonator serves as the detonation control wire. Due to the large area of ​​open-pit mines, a large number of detonation points need to be arranged during the mining process.

[0003] In the prior art, after the drilling of the blasthole is completed, the explosive bombs and detonators are generally carried manually to each blasthole for installation. However, the open-pit mine has a large area, a large number of blastholes, and a relatively harsh environment, so mechanized operations are gradually carried out. Since a long leg wire is connected to the end of the detonator, when a large number of detonators are carried together, the leg wires of the detonators are easily entangled with each other, making it impossible to sort out a single detonator. During the installation of the explosive bomb, it is necessary to connect the detonator with the explosive bomb, and lift the explosive bomb by the leg wire of the detonator and lower it into the blasthole. It is necessary to increase the stability of the connection between the detonator leg wire and the detonator head to prevent damage or even disconnection. During the mechanized operation, the transportation and transfer of the detonator is achieved by a rolling and squeezing mechanism, which requires increasing friction and providing elastic buffering to prevent over-extrusion.

It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.

[0033] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0034] For this example, please refer to Figure 1-6 The utility model provides an embodiment of a detonator and a detonator feeding device for use with explosive bombs.

[0035] Among them, an embodiment of a detonator used for detonating bombs is shown in Figure 1 , including a detonator body 610, a foot line 611, a buffer layer 612 and a clamping ring 613; the foot line 611 is inserted into the tail end of the detonator body 610, the buffer layer 612 is sleeved on the surface of the detonator body 610, the tail end of the detonator body 610 is provided with an annular groove 6101, one end of the clamping ring 613 clamps the tail end of the detonator body 610 and is inserted into the annular groove 6101 together with the buffer layer 612, and the other end of the clamping ring 613 is fixedly connected to the foot line 611 led out from the tail end of the detonator body 610. The buffer layer 612 is an elastic rubber layer, and the foot line 611 is a flexible wire.

[0036] In the above embodiment, the buffer layer 612 plays a protective role on the one hand. When the detonator feeding device feeds by squeezing the detonator surface, it can play a buffering role and increase the squeezing friction required for feeding; on the other hand, the buffer layer 612 is pressed by the clamping ring 613 into the annular groove 6101 behind the detonator body 610, which increases the stability of the connection of the clamping ring 613. The rear end of the clamping ring 613 is connected to the foot line 611. In the subsequent installation process of the detonator and the detonating bomb, when the detonating bomb is lifted by the detonator foot line, the foot line will not be loosened or even detached from the rear end of the detonating bomb. In summary, the stability and safety of the relevant operation process can be significantly improved.

[0037] Among them, an embodiment of a detonator feeding device is shown in Figure 2-6, including a flexible base belt, a support structure 63, a winding portion 631 and a feeding portion 632; and also including a plurality of detonators as described above, the detonators are arranged side by side on the surface of the flexible base belt, and the head end of the detonator exceeds the side of the flexible base belt (see Figure 5 The supporting structure 63 is arranged vertically, the winding portion 631 is arranged on one side of the supporting structure 63, the flexible base belt is hung on the supporting structure 63 and one side is connected to the winding portion 631, the winding portion 631 drives the flexible base belt and the detonator to move upward on one side of the supporting structure 63; the feeding portion 632 is arranged on the side where the detonator passes at the top of the supporting structure 63, and a notch 637 is provided at the bottom of the feeding portion 632. During the upward movement of the detonator, the head of the detonator enters the feeding portion 632 from the notch 637, and the feeding portion 632 draws the detonator out from the axial direction and sends it away.

[0038] In the above embodiment, the flexible base belt can be a woven fabric, a film with a certain strength, or other materials, which is essentially a soft sheet, serving as the installation base of the detonator. The winding part 631 winds the flexible base belt and moves. On the installation side of the feeding part 632, the head end of the detonator moves up and enters the feeding part 632 from the notch 637. The feeding part 632 extracts the detonator from the flexible base belt along the axial direction of the detonator and sends it to other places by contacting, squeezing and rolling the detonator. The advantages of the device in the above embodiment include: first, the storage state of the detonator is more orderly, and the leg lines of the detonator will not be entangled with each other, which is convenient for taking the detonator; on the other hand, the detonator can be automatically taken out, and other equipment can be used to realize the automatic installation of the detonator, improve the working efficiency, and realize the mechanized operation of the open-pit mine.

[0039] For further information, see Figure 5 and Figure 3 The flexible baseband includes a baseband body 621 and a plurality of side-by-side buckle groups, the buckle group includes a head buckle 622 and a line buckle 623, the head buckle 622 and the line buckle 623 are both arc-shaped, the degree of the arc is greater than 180 degrees, and they respectively clamp the detonator body 610 and the foot line 611. It should be noted that the number and spacing of the buckle groups can be set according to the length of the detonator and its foot line, and the setting method in the figure only provides a possible implementation method. The buckle group should ensure that the detonator and its foot line are stable and not easy to fall off from the flexible baseband laterally, but can be easily pulled out axially. Specifically, the degree of the buckle arc can be increased to form a larger encirclement angle for the detonator and the foot line to prevent them from falling out, while reducing the axial width of the buckle, thereby reducing the friction when pulling out from the axial direction, facilitating the pulling out operation.

[0040] This embodiment can be combined with Figure 5 and Figure 6The feeding part 632 includes a mounting platform 633, a main driving part 634 and an auxiliary driving part 635; the mounting platform 633 is fixedly connected to the supporting structure 63, the main driving part 634 is mounted on the mounting platform 633, and the auxiliary driving part 635 is mounted opposite to the main driving part 634. The middle of the main driving part 634 and the auxiliary driving part 635 is a driving area 636, and the lower part is a notch 637 for the detonator to enter; the main driving part 634 and the auxiliary driving part 635 clamp the detonator entering the driving area 636 through their respective rolling structures and extract it from the flexible base belt. After the detonator enters the driving area 636 from the notch, the main driving part 634 and the auxiliary driving part 635 in the driving area 636 squeeze and contact the detonator and the foot line to extract and send the detonator away.

[0041] In specific implementation, the rolling structure of the main driving part 634 includes a plurality of vertical rollers 6351 arranged along the axial direction of the detonator, and the rollers are synchronized by the friction belt 6341, and one of the rollers is driven by the power source. The rolling structure of the auxiliary driving part 635 includes a plurality of vertical rollers 6351 arranged along the axial direction of the detonator. By setting two different driving modes, the friction belt 6341 and the roller 6351, on both sides of the detonator and the foot line, the feeding effect can be increased and the feeding stability can be improved.

[0042] like Figure 6 As shown, in this embodiment, the auxiliary driving part 635 is telescopically connected to the main driving part 634, and the telescopic structure 638 is located on the upper side of the driving area 636. In this embodiment, the space of the driving area 636 is variable, which can ensure that detonators with different sizes of local and leg lines can be fed in; on the other hand, when the detonator enters, the space can be made larger for easy entry, and once it enters, the space can be made smaller for easy squeezing and feeding.

[0043] In this embodiment, the main driving part 634 is connected to the mounting platform 633. In addition to the detonator entering the driving area 636 by moving the flexible base band upward, the driving area 636 can also actively move downward to allow the detonator to enter the driving area, thereby enriching the functions and application scenarios of the device.

[0044] Furthermore, a detonator guide structure is provided in the middle of the lower side of the main driving part 634 and the auxiliary driving part 635, which can ensure that the detonator accurately enters the driving area 636, thereby increasing the stability and reliability of the device.

[0045] In summary, the utility model effectively overcomes various shortcomings in the prior art, can produce beneficial technical effects, and has significant progress.

[0046] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
