A kind of emulsified explosive charging machine

Abstract

The invention provides an emulsion explosive loading machine which comprises a frame, an automatic hole aligning system, a delivery and retreating tube system and a material conveying and sensitizing system. The automatic hole aligning system comprises a camera, a remote control large arm and a remote control operating table. The delivery and retreating tube system comprises a tube coiling machine, a tube arranger and a tube sender. A rotary joint is installed at the axis of the tube coiling machine. The rotary joint consists of a fixed joint and a moveable joint. The moveable joint is connected with the outlet of a material conveying pump. The fixed joint is connected with an explosive conveying hose. The rotary joint is provided with a circular channel structure, so that a sensitizer and a sensitization accelerant are separated by a latex matrix to be conveyed in layers with the same stream tube. Stored materials in a material storage tank are pumped by the material conveying pump and are delivered to a blasthole through the rotary joint, the explosive conveying hose and a tubular mixer installed at the tail end of the explosive conveying hose. The loading machine is driven by four hydraulic wheels and realizes remote control of automatic hole alignment, delivery and retreating tube of the explosive conveying tube, loading at the blasthole and loading parameters through the remote control operating table. The whole machine is high in automatic degree, the explosive is sensitized in the blasthole, and the intrinsic safety is high.

Description

technical field [0001] The invention belongs to the field of mining machinery and equipment, and relates to an emulsion explosive charging machine, which is particularly suitable for filling emulsion explosives in medium and deep hole blasting in complex environments such as underground mines. Background technique [0002] my country has a vast land and abundant resources, and the natural environment varies greatly. Each blasting operation has its own special conditions. There are few large-scale open-pit mines with large-aperture blasting. The use of strip-shaped rolls of explosives has greatly restricted the use of open-air emulsion explosives on-site mixing vehicles with basically mature technology in my country. The traditional blasting and excavation method of finished strip-shaped charge, due to the low charge density of the manual charge and the poor coupling between the explosive and the blasthole, generally has the defect of low utilization rate, especially in underg...
