Abstract
Description
Technical Field
[0001] This utility model belongs to the field of blasting engineering machinery technology, specifically relating to a detonator filling device after drilling. Background Technology
[0002] In mining, tunneling, and rock blasting engineering, borehole blasting is a core construction step. The process includes borehole formation, emulsion explosive filling, detonator installation, and detonation network connection. Traditionally, emulsion explosives are injected into the borehole via pumping equipment, while detonators must be manually inserted into designated positions (lower, upper, or middle) within the explosive to ensure reliable detonation. Because borehole depths often reach several meters to tens of meters, and the working environment presents risks such as borehole collapse and residual rock dust, manual detonator placement suffers from low operational precision, high safety risks, and low efficiency, severely restricting the quality and progress of blasting projects. Utility Model Content
[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a detonator filling device after drilling, which solves the problems of high safety risks and low efficiency of manual filling of explosives and detonators in the prior art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: This utility model includes a track structure, an explosive pump, a filling moving seat movably mounted on the track structure, a filling rod extending from the filling moving seat, a filling telescopic cylinder mounted on the filling moving seat, and a detonator holder detachably mounted at the end of the track structure. The filling rod has an axially oriented orifice for transmitting emulsion explosive and a placement hole for accommodating detonators. The emulsion explosive output from the explosive pump is conveyed to the orifice via the filling moving seat. A stop rod is fixedly provided at the end of the filling telescopic cylinder, and the stop rod slides along the placement hole. When the filling telescopic cylinder extends, it pushes the detonator out of the placement hole. A limiting groove, co-located with the placement hole, is provided on the side of the output end of the filling rod. The detonator holder includes a housing with a detonator receiving cavity, a guide rail fixed to the housing, a loading trolley moving along the guide rail, and a push rod fixed to the loading trolley. The push rod extends into the detonator receiving cavity and pushes the detonator into the limiting groove.
[0005] Optionally, a first elastic block is provided on each side of the limiting groove, and the first elastic block is a wedge-shaped structure.
[0006] Optionally, a second elastic locking block is provided on both sides of the outlet of the detonator receiving cavity of the shell chamber, and the second elastic locking block is a wedge-shaped structure.
[0007] Optionally, the output end of the filling rod has a square head structure, and the limiting groove is formed on the side of the square head structure.
[0008] Optionally, the number of filling telescopic cylinders is equal to the number of insertion holes.
[0009] Optionally, the tube loading vehicle abuts against the outermost detonator inside the detonator receiving cavity via a push rod.
[0010] Optionally, the detonator holder and the track structure are detachably connected.
[0011] Optionally, the wedge-shaped inclined surfaces of the first and second elastic blocks face the direction of detonator movement.
[0012] Optionally, the filling moving seat moves along the track structure via a motor drive mechanism.
[0013] Optionally, the insertion hole and the drug port are opened parallel to each other inside the filling rod.
[0014] The beneficial effects of this utility model are as follows: This device is used to replace manual operation after drilling, filling the borehole with emulsion explosives and detonators. A multi-link structure allows the filling rod to move to the borehole. With the movement of the filling moving seat, the filling rod extends into the borehole, eventually reaching the bottom. Through the operation of the explosive pump, the emulsion explosive flows out through the output end of the filling tube and gradually fills the borehole to the required depth. Before the filling rod extends, the detonator is placed in the placement hole. It extends into the borehole with the filling rod and moves with the retraction of the filling rod after the emulsion explosive filling is complete. After the filling rod moves upward a certain distance, it pushes the filling telescopic cylinder, pushing the detonator out of the placement hole and retaining it inside the emulsion explosive. In this embodiment, two placement holes are provided, allowing the detonator to be placed in the lower and upper sections of the emulsion explosive section to ensure successful detonation. This device, by setting a filling structure that can fill emulsion explosives and retain detonators in one go, replaces manual filling of emulsion explosives, ensuring the detonator is accurately placed in the required position. The operation is continuous, fast, and has high filling efficiency. Simultaneously, a detonator holder and a limiting groove structure are set at the end of the filling rod. The detonator holder is used to hold a certain number of detonators. The detonators are arranged and placed, and under the push of the detonator loading vehicle, they are inserted into the limiting groove from the side of the filling rod to realize the automated single installation of detonators. The first elastic locking block and the second elastic locking block temporarily limit the detonators in the detonator receiving cavity and the limiting groove, respectively, to prevent them from falling out. This device can load multiple detonators at one time. During the drilling and explosive filling process, multiple manual loading is not required. The next required detonator can be loaded when the filling rod is in the retracted state, which improves the working efficiency of this device.

Therefore, they have no substantial technical significance.

[0019] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.
[0020] This utility model provides a device for inserting detonators after drilling, such as Figures 1-6 As shown, the device includes a track structure 1, an explosive pump 2, a filling moving seat 3 movably mounted on the track structure 1, a filling rod 4 extending from the filling moving seat 3, a filling telescopic cylinder 5 mounted on the filling moving seat 3, and a detonator holder 6 detachably mounted at the end of the track structure 1. The filling rod 4 has two axially oriented holes: a propellant hole 41 for transmitting emulsion explosive and a detonator placement hole 42. There are two placement holes 42, located on either side of the propellant hole 41, parallel to the propellant hole 41 inside the filling rod 4. The explosive pump 2 outputs emulsion explosive, which is then conveyed to the propellant hole 41 via the filling moving seat 3. The filling telescopic cylinder 5 has a fixed abutment 7 at its end, which slides along the placement hole 42. When the filling telescopic cylinder 5 extends, it pushes the detonator out of the placement hole 42. The output end of the filling rod 4 has a square head structure. The limiting groove 43 is opened on the side of the square head structure. The side of the output end of the filling rod 4 is provided with a limiting groove 43 that is in the same position as the tube hole 42. The limiting groove 43 is provided on both sides. The first elastic block 44 is a wedge-shaped structure facing the detonator. The detonator holder 6 includes a shell chamber 61 with a detonator receiving cavity, a guide rail 62 fixed to the shell chamber 61, a tube loading trolley 63 that moves along the guide rail 62, and a push rod 64 fixed to the tube loading trolley 63. The tube loading trolley 63 abuts against the outermost detonator in the detonator receiving cavity through the push rod 64. The push rod 64 extends into the detonator receiving cavity and pushes the detonator into the limiting groove 43. The shell chamber 61 is provided with a second elastic block 65 on both sides of the detonator receiving cavity outlet. The second elastic block 65 is a wedge-shaped structure facing the detonator.
[0021] This device is used to replace manual operation after drilling, filling the borehole with emulsion explosives and detonators. The multi-link structure allows the filling rod 4 to move to the borehole. With the movement of the filling moving seat 3, the filling rod 4 extends into the borehole, eventually reaching the bottom. Through the operation of the explosive pump 2, the emulsion explosives flow out from the output end of the filling tube and gradually fill the borehole to the required depth. Before the filling rod 4 extends, the detonator is placed in the insertion hole 42 and extends into the borehole along with the filling rod 4. After the emulsion explosives are filled, the detonator is removed from the borehole. The rod 4 is retracted and moved. After the filling rod 4 moves up a certain distance, it pushes the filling telescopic cylinder 5, which pushes the detonator out of the placement hole 42 and keeps it inside the emulsion explosive. In this embodiment, two placement holes 42 are provided, which can leave the detonator in the lower and upper sections of the emulsion explosive section to ensure successful detonation. This device replaces manual filling of emulsion explosive by setting a filling structure that can fill the emulsion explosive and retain the detonator at one time, ensuring that the detonator is accurately placed in the required position. The operation is continuous and fast, and the filling efficiency is high. Simultaneously, a detonator holder 6 and a limiting groove 43 structure are set at the end of the filling rod 4. The detonator holder 6 is used to place a certain number of detonators. The detonators are arranged and placed, and under the push of the detonator loading vehicle 63, they are inserted into the limiting groove 43 from the side of the filling rod 4 to realize the automated single installation of detonators. The first elastic locking block 44 and the second elastic locking block 65 temporarily limit the detonators in the detonator receiving cavity and the limiting groove 43 respectively to prevent them from falling out. This device can load multiple detonators at one time. During the drilling and explosive filling process, multiple manual loading is not required. The next required detonator can be loaded when the filling rod 4 is in the retracted state, which improves the working efficiency of this device.
[0022] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
