Mechanized continuous charge system for surface blasting

Abstract

The invention discloses a surface blasting mechanization continuous powder charging system. A rack (2) is supported on a travelling mechanism (1); a power system (3), a hydraulic system (4) and a control system (5) are mounted on the rack (2); one end of a support arm (6) is fixed on the travelling mechanism (1), and the other end of the support arm (6) is connected with a combined telescopic arm (7) downwards perpendicular; a hoisting oil cylinder (11) and a rotary oil cylinder (12) are arranged on the support arm (6); a telescopic oil cylinder (13) and a depth indicator (8) are arranged on the combined telescopic arm (7); the hydraulic system (4) communicates with the hoisting oil cylinder (11), the rotary oil cylinder (12) and the telescopic oil cylinder (13) through a hydraulic oil pipe (16); and the control system (5) controls operation of the support arm (6) and the combined telescopic arm (7) and controls open-close of a gripper (10) through the hydraulic system (4). The surface blasting mechanization continuous powder charging system can realize mechanization of the powder charging process, avoids the powder cut-off phenomenon, eliminates the misfire accident caused by discontinuous powder charging and improves the security of blasting operation.

Description

technical field [0001] The invention belongs to the technical field of blasting engineering, and in particular relates to a blasting charge machine for open-pit mining, which is suitable for open-air blasting projects with a vertical drilling diameter ≥ 150mm and using emulsion explosive rolls, which can better ensure the continuity of charge and avoid Blind shot accidents caused by discontinuous charging, and mechanized charging can significantly improve the efficiency of charging, reduce the labor intensity of blasting operations, and ensure the safety of blasting operations. Background technique [0002] In open-pit mines, earth-rock blasting and other open-pit blasting projects, the discontinuity of explosive charge is one of the main causes of blind shot accidents. Generally, the explosives used in open-air blasting are divided into two types: powdered explosives and emulsion explosives; at present, the former has realized the mechanized continuous charging of the charg...
