Further, the center of the baffle offers through-hole, and the direction of explosion mouth is in be staggered everywhere.
Further, the extension of the top plate offers positioning hole.
In comparison with existing structure, the utility model has the following advantages that:
1. the setting of the utility model baffle, baffle can will make the explosion inside gun barrel be classified progress, and relative closure is only
Vertical, influencing each other between reduction is at different levels, the direction of explosion mouth is mixed everywhere carries out staggeredly, to make explosion staggeredly orient, explosion
It impacts vibratory forces and interlocks in lithosphere along explosion mouth everywhere and four dissipate, be conducive to the generation in crack, keep the effect of explosion more preferable.
2. the setting of the utility model arch support item, arch support item can reinforce the structural strength of gun barrel, for arch
Shape is arranged, and can absorb the impact force that part explosion is brought, reduce injury of the explosion to blasthole, blasthole wall is smooth after raising is quick-fried
Degree reduces the damage of explosive opposite side slope surface.
3. the extension of the setting of the utility model top plate, top plate offers positioning hole, setscrew is inserted into and is positioned
Inside mounting hole, and then top plate is anchored on the side slope face of gun barrel top peripheral, setscrew can be more firm by top plate
Be fixed on side slope face, when avoiding explosion, under the action of impact force occur concussion displacement destroy blasthole structure.
