Abstract
The utility model relates to a demolition cleavage crack apparatus, belonging to the stone mining field, which is composed of a column circular pipe, a partition board in the circular pipe, and the cushioning medium between the partition board and the circular pipe; the partition board is arranged in the circular pipe in parallel; the demolition cleavage crack apparatus can avoid generating the demolition cleavage crack on the other directions, the utilization of the explosive energy can be improved, and the labor intensity can be reduced.
Description
The utility model relates to the splitter in a kind of stone material field of mining, particularly explosion splitter.
In interim a kind of " buffering voltage stabilizing explosion marble and the granite " patent of invention of having announced of Chinese patent communique, the patent No. (87102363.6).This patent has been announced a kind of splitter, form by the buffer medium between cylindricality pipe, concentric dividing plate and dividing plate and the pipe, see Fig. 1 and Fig. 2, can cushion voltage stabilizing explosion marble and granite, weak point is: the first, because Explosive roll is positioned at the center of pipe, it is round that powder stick is, and the round wall pressure power in big gun hole is in isopiestic state during explosion, and can not guarantee the direction cracking of rock along design fully.The second, can not make full use of the energy of explosive.The pitch-row of the 3rd powder charge is overstocked, and the aperture is excessive, has caused the waste of human and material resources.
The purpose of this utility model provides a kind of explosion splitter, and rock can only split along the direction of design when it guaranteed explosion, avoids other directions to produce the crack, improves the utilization rate of explosive energy; Reduce labor intensity.
The purpose of this utility model realizes by following measure: a kind of explosion splitter that is used for the stone material field of mining, form by cylindricality pipe and interior dividing plate dividing plate thereof and the buffer medium between the pipe, it is characterized in that: dividing plate is placed in parallel in the pipe, the ratio of pipe diameter phi and width h is between 2.6～3.5, the equivalent diameter of area of space is between 16mm～26mm, and pipe is made by materials such as plastics or paper.
The utility model mainly is to be become by cylindricality pipe, dividing plate and buffering media pack, wherein the cylindricality pipe by and parallel baffle between for handing over bonding to close, pipe and parallel baffle are that same material is made, and after pipe and dividing plate made, the semicircular area between pipe and dividing plate was filled buffer medium.Buffer medium is materials such as air, water.After the area of area of space amounted to into the area of a circle, its equivalent diameter scope was between 16mm～26mm.
Advantage of the present utility model is: concentration of energy on the direction that precut, the superposition of stress wave makes this place at first produce crack and expansion, other direction upper stress ripples lag behind and arrive in the big gun hole wall, only play the effect of quasi static pressure, guarantee the reliability and the accuracy of explosion cutting, improved the famine material rate of stone material, made full use of the energy of explosive, owing to the superposition of stress wave, it is more smooth that the rear surface is cut in explosion simultaneously.In addition, after the Explosive roll explosion, the compression on the cut direction increases, and corresponding pitch-row increases than prior art, has reduced the boring workload.
Drawing is described as follows:
Fig. 1 is the prior art front view.
Fig. 2 is the prior art cutaway view.
Fig. 3 is the utility model front view.
Fig. 4 is the utility model cutaway view.
Fig. 5 is the utility model presplitting direction schematic diagram.
The utility model is described in further detail to utilize the example shown in the accompanying drawing.In the schematic diagram of Fig. 3, Fig. 4 and explosion splitter shown in Figure 5, parallel placement dividing plate 3,4 in the cylindricality pipe 1 is filled padded coaming 2 in the semicircular area between pipe 1 and parallel- plate 3,4, and pipe 1 is to be made by plastics or paper.The ratio of the width L in the diameter phi of pipe 1 and space is between 2.6～3.5.The equivalent diameter of area of space is between 16～26mm.
Claims (4)
1, a kind of explosion splitter that is used for the stone material field of mining is made up of cylindricality pipe and interior dividing plate thereof and the buffer medium between dividing plate and the pipe, and it is characterized in that: dividing plate is placed in parallel in the pipe.
