Description

Technical Field

[0001] The utility model relates to the technical field of blasting mechanisms, in particular to a blasting device with a directional blasting mechanism. Background Art

[0002] Directional blasting uses the effect of explosives to throw earth and stone from a certain area to a designated area and roughly pile it into the required shape. It is mainly used for dam repair, road construction, land leveling, etc. It is particularly suitable for work sites with a lack of labor, inconvenient transportation and no construction site. Blasting is to relieve the pressure of a non-heavy-closed overpressure relief device to complete the blasting work.

[0003] Although the existing blasting device achieves the function of convenient directional blasting through the coordinated use of a limit rod, a spring, a ring, a movable plate, a guide rod and a directional tube during use, and the detonator can be ejected to a specified position by resetting the spring to improve the blasting efficiency, in the actual blasting process, the compression degree of the spring cannot be adjusted according to the launching distance, which makes it only suitable for launching at one blasting distance. Therefore, a blasting device with a directional blasting mechanism is urgently needed to solve the above problem. Utility Model Content

When the power is off, the fixation is released, and the detonator can be launched by relying on the rebound force of the telescopic column and the spring. At the same time, the electric push rod can adjust the position of the electromagnet according to the actual range of the detonator, and then adjust the compression degree of the spring, so that it can launch detonators of different ranges, effectively improving its applicability and use effect.
