Description

Technical Field

[0001] The invention relates to the technical field of a feeding mechanism for an underground emulsion explosive charging vehicle, in particular to a feeding mechanism for an underground emulsion explosive charging vehicle. Background Art

[0002] Emulsion explosives are a new type of industrial explosive developed in the 1970s. They are made by using emulsifiers to evenly disperse droplets of aqueous oxidant salt solutions in an oil-phase continuous medium containing porous substances such as dispersed bubbles or hollow glass microspheres to form an oil-in-water type latex explosive.

[0003] In the prior art, a feeding mechanism for an underground charging vehicle for emulsion explosives disclosed in Chinese patent CN202321325391.5 includes: a first support frame, a container, a fixed plate, a connecting rod, a rotating column, a belt, and a feeding frame. A container for loading explosives is placed on the upper part of the first support frame, and two fixed plates facing each other are connected to the right side of the first support frame. A connecting rod is rotatably provided in the middle of the fixed plate, and a rotating column is connected to the connecting rod. A belt is connected between the two connecting columns, and multiple feeding frames for conveying materials into the container are connected to the outside of the belt. The belt is driven by a stepper motor to drive the feeding frame to rotate and pour the explosives into the container, thereby conveniently completing the operation of automatic charging, without the need for multiple fixed personnel to carry it, and the operation is convenient and the safety risk is low.

[0004] Although it solves the problem of the prior art that emulsion explosives do not require multiple fixed personnel for loading and are easy to operate, when passing through the feeding mechanism, some emulsion explosives will still remain on the feeding assembly. Over time, the explosives will accumulate on the feeding mechanism and be difficult to clean. Moreover, when the emulsion explosives are poured into the container, dust will be generated and scattered in the surrounding cavity, seriously increasing the safety risk. Summary of the invention
