Abstract
The utility model relates to a stone crushing bomb which is used for the secondary crushing of large rocks, composed of a detonator (1), explosive (2), crushing dregs (3), a housing (4), and a cylindrical groove (5). The housing (4) of the stone crushing bomb can be made of cheap materials, such as plastic, hardboards, asphalt felt, etc.; the explosive (2) can be violent explosive or the mixing of other cheap oxide or inert materials; the crushing dregs (3) are used for increasing the impact of the stone crushing bomb. In a word, the utility model has the advantages of simple structure, low fabrication cost, convenient use, and high utilization rate of the energy of the explosive.
Description
The utility model belongs to the cap explosive demolition set, particularly to the fragmentation Stone crushing bomb of large rock mass.
At present the technological process of boring-powder charge-blow out is adopted in the large rock mass second-time breakage usually in mining industry.Sometimes also adopt adobe blasting (promptly explosive being placed on rock surface), this charging means amount of consumption of drugs is big, and air-shock wave is strong, and is destructive strong to the surrounding buildings thing, and also dangerous to the people.The energy-gathering jetting that also useful high explosive anti-tank cartridge produces destroys rock, the shortcoming of this blasting method is a high explosive anti-tank cartridge manufacturing process complexity, cost an arm and a leg, also there is human emission big gun emission concrete projectile to impact the purpose that rock reaches second-time breakage, though this bullet is cheap, but need to be equipped with the emission big gun, total cost is also very high.
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of simple in structure, cheap, easy to use, the Stone crushing bomb that the explosive energy utilization rate is high.
Accompanying drawing is a section of structure of the present utility model
(1) is detonator among the figure
(2) be explosive
(3) be disintegrating slag
(4) be shell
(5) be groove
Above-described Stone crushing bomb is to include detonator (1), explosive (2) and shell (4), it is characterized in that a columniform groove (5) is arranged below Stone crushing bomb. Rubble Groove below the bullet (5) can also be other shape, such as taper, trapezoidal, rectangle. The upper bottom portion of the groove below Stone crushing bomb (5) is equipped with one deck disintegrating slag (3), said disintegrating slag (3) is husky with sand or iron or all can with other hard disintegrating slag, the effect of disintegrating slag (3) is exactly after the Stone crushing bomb blast, utilize the hardness of disintegrating slag to give bigger impulsive force of rock, increased Stone crushing bomb and impacted intensity of wave. Shell described in the accompanying drawing (4) can use that the prices such as plastics, hardboard, asphalt felt are cheap, intensity is low, the material of easy-formation is made, and the shape of shell (4) is cylindrical, also can be square or polygon. Explosive described in the accompanying drawing (2) is to be mixed by high explosive (such as hexogen, TNT) and other cheap oxide (such as ammonium nitrate, barium nitrate, red lead powder etc.) or inert material (such as gypsum, latex, salt etc.), explosive is powdery, also can be colloid or solid. Described detonator (1) is contained in the Stone crushing bomb center upper portion.
Embodiment:
1. the Stone crushing bomb shell is made cylindrical outer cover (4) by strawboard, and explosive (2) is composite explosives (ladder is thought ladder and barium nitrate), and rock is a limestone, and after the Stone crushing bomb blast, catalase becomes four, no slungshot.
2. the Stone crushing bomb shell is made cylindrical outer cover (4) by strawboard, and explosive (2) is mixed by 8321 explosives and ammonium nitrate, and rock is a limestone, and after the Stone crushing bomb blast, catalase becomes some, no slungshot.
3. the Stone crushing bomb shell is made cylindrical outer cover (4) by asphalt felt, and explosive (2) is mixed by hexogen and epoxy resin, and rock is a limestone, and after the Stone crushing bomb blast, rock rupture becomes many fragments, no slungshot.
More than three embodiment can load onto one deck disintegrating slag (3) in the upper bottom portion of groove (5), disintegrating slag (3) can be sand or iron sand.
Great advantage of the present utility model is exactly that cost is low, the rear no slungshot of blast.
Claims (3)
1, a kind of Stone crushing bomb that includes detonator (1), explosive (2) and shell (4) is characterized in that a columniform groove (5) is arranged below Stone crushing bomb, in the upper bottom portion of groove (5) one deck disintegrating slag (3) is housed.
By claim 1,2 described Stone crushing bombs, it is characterized in that 2, the groove (5) below the Stone crushing bomb can also be other shape, as taper, trapezoidal, rectangle.
By the described Stone crushing bomb of claim 1, it is characterized in that 3, one deck disintegrating slag (3) of adorning in the upper bottom portion of groove (5) is with sand or iron sand.
