Problems solved by technology

[0003] At present, the main method of cutting strip-shaped explosive rolls is to use a utility knife to cut strips one by one on-site by blasting operators based on their operating experience and subjective feelings. Not only does the weight of the strips vary greatly, but it is also dangerous and inconvenient to operate, and the work efficiency is low. and pollution and waste
In particular, the deviation in the weight of explosives is likely to lead to insufficient crushing of load-bearing components or serious "flying stones", which become an important factor affecting the safety of blasting operations and blasting effects

Embodiment 1

[0035] like Figure 1-3 As shown, this embodiment provides an explosive charge coil cutting device, which is mainly composed of a blade plate 4, a charge coil placing plate 9, an operating handle 1, a buckle 10 and a clamping hole 11. The buckle 10 and the clamping hole 11 can be Close and fasten to ensure safe operation and storage.

[0036] In this specific embodiment, as figure 1 and 3 As shown, the blade disc 4 is mainly composed of a blade 2, a lead screw 3, an adjusting nut 6 and a scale 5. The blade 2 can be flexibly mounted and dismounted, accurately positioned and reliably fixed, and distributed according to the required explosive length, and can be accurately cut Dynamite rolls.

[0037] In this specific embodiment, as figure 1 and 2 As shown, the medicine roll placing tray 9 is mainly composed of a card slot 8 and a medicine roll support 7, and the medicine roll support 7 can be flexibly installed according to the required number.

Abstract

The invention discloses a device and method for cutting an explosive cartridge and relates to the field of detonation. The cutting device comprises a cartridge placing disk and a blade disk; the cartridge placing disk is used for placing the cartridge; a plurality of blades are arranged in the blade disk at intervals; and the distance between the adjacent blades is adjustable and is equal to a length of the required cartridge. By the device and method, the quality of a cartridge bag can be accurately controlled, operation is facilitated, the working efficiency is high, and the problems of large deviation of cartridge bag weight, dangerous and inconvenient operation, low working efficiency, pollution waste and the like in the traditional manual cutting method are solved.

Description

technical field [0001] The invention relates to the field of blasting, in particular to an explosive charge coil cutting device and a cutting method. Background technique [0002] Most of the blast holes in the blasting demolition project have a diameter of about 40mm, and the number of blast holes is 100 to 10,000. The explosive used is φ32mm strip-shaped emulsion explosive, which is a stereotyped product packaged in blown film: 300g in weight and 30cm in length, i.e. 10g / cm . In the actual blasting demolition project, the charge amount of a single blast hole is mostly 30g~150g (limited by the performance of the detonating cap and emulsion explosive, in the blasting demolition project, the charge amount of each hole should not be less than 30g, that is, the length of the charge is not less than 30g). less than 3cm). Therefore, a large number of equal-quality charge packs need to be cut at the blasting construction site. [0003] At present, the main method of cutting str...
