Technical Field

The invention relates to the technical field of blasting devices, in particular to a spiral annular energy-gathered cutting liner.

Background

In the process of carrying out open-air deep hole bench blasting, the problem that the root bottom rate is higher generally exists. The resulting working face is uneven, thus resulting in a substantial reduction in the transport efficiency of the transport equipment. Unevenness of the road surface during transportation can also cause ores to fall off during transportation, resulting in loss of the ores and even a series of safety problems. Handling these rough mining surfaces also increases the cost of mining. Meanwhile, in the open-air deep hole step blasting process, a new working surface after blasting is expected to be flat, so that a plurality of advantages can be brought in the later operation process. Therefore, some measures need to be taken to solve the problem.

If it is desired to make the new working surface flat after blasting, the problem of high root rate is solved first. The root bottom mainly occurs at the bottom of the blast hole, and in order to overcome the resistance of the chassis to the line, the explosive is mainly placed at the middle and bottom of the blast hole. The lower part rock has great clamping effect, needs to be reinforced at the bottom for charging, and needs to be drilled for ultra-deep treatment, so that the length of the drilled hole is increased, and the using amount of explosive is increased.

Disclosure of Invention

In order to solve the technical problems, the invention provides the spiral annular energy-gathered cutting liner, which reduces the explosive consumption and forms a smoother new working surface by gathering the energy of the explosive.

In order to achieve the purpose, the invention provides the following scheme:

the invention provides a spiral annular energy-gathering cutting liner, which comprises a cover body, wherein the cover body is of a spiral thin-wall structure, and two sides of the cover body are bent towards the same direction to form a groove with a parabolic section.

Optionally, the wall thickness of the cover is no greater than 2 mm.

Optionally, the cover body is made of a metal material.

Optionally, the cover body is made of red copper or pig iron.

Optionally, the minimum diameter of the inside of the housing is smaller than the diameter of a cartridge used in the field.

Optionally, the minimum diameter of the inside of the cover is 0-3mm smaller than the diameter of a cartridge used in the field.

Optionally, the spiral structure of the cover body is not less than two turns.

Compared with the prior art, the invention has the following technical effects:

1. the spiral annular energy-gathering cutting liner has a simple structure, is convenient to operate when used on the spot, and does not influence the construction speed on the spot. Meanwhile, when the device is used for on-site worker construction, the device is simple and convenient to install, and the working strength of workers is reduced.

2. The spiral annular energy-gathering cutting liner disclosed by the invention is small in processing difficulty, low in material cost, low in manufacturing cost, high in flexibility in field construction, flexible in strain according to field conditions and high in adaptability. The novel packaging box is convenient to store, small in size, small in occupied space, wide in applicability, easy to process and manufacture, low in material cost and obvious in superiority.

3. According to the spiral annular energy-gathered cutting liner, the liner does not bear the pressure of the upper cartridge, and the problem of poor expected blasting effect caused by crushing is solved.

4. The spiral annular energy-accumulating cutting liner disclosed by the invention can accumulate energy on one plane, and simultaneously spiral in the axis direction, and the planar jet flows accumulated by a plurality of planes are superposed to form annular jet flows, so that the cutting effect on the hole bottom is more obvious.
