AI Technical Summary
Technical Problem
The delivery hose of existing explosive charging devices cannot be effectively fixed, causing it to sway or shift inside the hole, rubbing against the hole wall, hindering the flow of explosives, and reducing charging efficiency.
Method used
A fixing assembly including a fixed ring, a rotating ring, a drive column, and a friction pad was designed. The delivery hose is fixed by the coordinated movement of bolts and connecting columns to prevent shaking or displacement. At the same time, a motor-driven stirring blade is used to prevent the powdered explosive from clumping.
Benefits of technology
It achieves stable fixation of the delivery hose, ensuring smooth delivery of explosives, preventing clumping, and improving loading efficiency.

Abstract
The utility model relates to the technical field of explosive charge and discloses a long charge device for blasting, comprising a bottom plate; a charge assembly is arranged on the top of the bottom plate; a fixing assembly is arranged on one side of the charge assembly; the fixing assembly comprises a fixing ring, a movable groove is formed in the inside of the fixing ring, and a rotating ring is arranged in the inside of the movable groove. The utility model inserts the conveying hose into the hole where gunpowder needs to be conveyed, moves the fixing ring into the hole, rotates the bolt, slides the bolt, drives the rotating ring to rotate through the connecting column, drives the extruding block and the friction pad to move through the driving column, extrudes the outside through the movement of the extruding block and the friction pad, rotates the bolt to extrude the fixing plate to ensure that the connecting column does not move, thereby fixing the conveying hose, preventing shaking or deviation when conveying gunpowder.
