Description

Technical Field

[0001] The utility model relates to the technical field of blast hole plugs for mine blasting, in particular to a blast hole plug for mine blasting. Background Art

[0002] While large-diameter holes bring better economic benefits, they also pose new safety hazards to mine production. The reason is that the hole diameter is too large and the hole opening is not well protected, resulting in the risk that miners may step into the void and get their legs, arms or other tools stuck in the blast holes. In production, it is common for electronic devices such as mobile phones and walkie-talkies to accidentally slip into the blast holes, which not only causes economic losses, but also the batteries of the electronic devices may pose greater risks when filling the blast holes with explosives. At the same time, some sundries such as stones, stone powder and soil at the hole opening may also slip into the blast holes, causing blockage or reducing the hole depth, thus affecting the blasting effect. At present, to prevent the occurrence of the above situations, generally, the blast holes are temporarily sealed with the packaging bags or cartons of detonators and explosives, or even a slightly larger stone is found near the hole opening.

[0003] However, in the prior art, these existing methods not only cannot completely seal the hole opening, but also have very poor compressive resistance and cannot protect pedestrians and vehicles from the damage of the blast holes. More dangerously, this simple sealing will give people the misunderstanding that the risk has been controlled, increasing the possibility of more serious dangers. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art, and to propose a blast hole plug for mine blasting.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A blast hole plug for mine blasting, comprising a top component, a connecting component and a bottom component; the top component includes a connecting piece, a backlight reflector is installed on the top of the connecting piece, and a reflective sticker is arranged on one side of the backlight reflector; the connecting component includes an inverted conical plug, an arc block is installed at the bottom of the inverted conical plug, two convex grooves are opened inside the inverted conical plug, and arc grooves are opened on one side of the two convex grooves; the bottom component includes a base, a sand layer is arranged on the outer surface of the base, a sealing ring is arranged on the outer surface of the base, a sealing groove is opened on the top of the base, a convex plate is installed on the top of the base, a threaded block is installed on the outer surface of the convex plate, and two convex blocks are installed on the outer surface of the convex plate.

[0006] Preferably, the backlight reflector is fixedly installed with the connecting piece, and the reflective sticker is adhesively connected with the backlight reflector.

[0007] Preferably, the arc block is fixedly installed with the inverted conical plug, and the arc groove communicates with the two convex grooves.

[0008] Preferably, an anti-slip surface is provided on the outer surface wall of the inverted conical plug, and the sealing ring is sleeved and connected to the base.

[0012] 1. In the present utility model, the backlight reflector can effectively prompt the approaching personnel to avoid at night. The connecting piece can increase the height of the backlight reflector to make it more easily recognizable. The inverted conical plug can fully adapt to the orifice size of the blast hole to achieve the purpose of dead-end plugging, preventing sundries from falling into the blast hole. At the same time, the wooden structure is light and can provide good compressive resistance, so that even if it is trampled or rolled, it can ensure that equipment such as people or vehicles will not sink into the blast hole.

[0013] 2. In the present utility model, a sand layer and a sealing ring are provided on the outer surface wall of the base, which can expand when encountering water, resulting in better sealing performance.
