Finished ammonium nitrate fuel oil explosive charging machine

Abstract

The invention discloses a finished ammonium nitrate fuel oil explosive charging machine. The machine comprises a control box and an explosive supply device. The explosive supply device forms continuous conveying and explosive supply through an explosive conveying screw, the outlet end of the explosive conveying screw is connected with an explosive charging screw, the explosive charging screw is coaxially and fixedly connected with the explosive conveying screw, the explosive charging screw is located in an explosive charging barrel, and the explosive charging barrel is suspended above a workbench. The workbench is provided with a travel switch which is electrically connected with the control box. The explosive charging machine has the beneficial effects that the explosive charging machineis installed on a site where the mixed loading explosive truck can reach conveniently, the mixed charging explosive truck is connected to complete subsequent explosive loading work, and the mixed charging explosive truck only needs to provide finished ammonium nitrate fuel oil explosives for the explosive charging machine; The blasting operation requirement of a road platform imperfect or narrow operation surface which cannot be effectively reached by a mixed charging explosive truck is met. The explosive charging machine is used for charging the ammonium nitrate fuel oil explosives into cartridges with film sleeves, has certain waterproofness, can be used for blast holes with a small amount of water, and is light in weight of a single cartridge, adjustable in diameter and length of the cartridges and wider in application range.

Description

technical field [0001] The invention belongs to the technical field of civil explosives, and in particular relates to a charging machine for finished ammonium oil explosives. Background technique [0002] At present, domestic ammonium oil explosives are generally transported at the ground station to transport porous granular ammonium nitrate and diesel oil separately and store them in different feed boxes of mixed ammonium oil explosives vehicles. After the mixed ammonium oil explosives vehicles are driven to the blasting site, they are mixed on site. After the porous granular ammonium nitrate and diesel oil are uniform, they are sent into the blast hole for use. For the working environment where the ammonium fuel explosive vehicle cannot be driven into, such as the road platform is not perfect, the narrow working surface scene, and the mixed ammonium fuel explosive cannot be effectively used when there is a small amount of water in the blast hole, this kind of operation met...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems in the prior art that ammonium oil explosives cannot be efficiently applied to imperfect road platforms, narrow working surfaces, and a small amount of water in blastholes, and provide a finished ammonium oil explosive charging machine. By connecting the charging screw and the drug roll carrying platform in series at the outlet section of the drug delivery screw of the drug supply device, and by installing a plastic tube film sleeve on the charge screw, the ammonium oil explosive is packed into a drug roll with a film cover, which has a certain Waterproof, it can be used in blastholes with a small amount of water. At the same time, a single cartridge is light in weight, and the diameter and length of the cartridge can be adjusted. It can be used in a wider range of scenarios. It can be manually sent to road platforms with imperfect or narrow working surfaces. Blasting operation
