Description

Technical Field

[0001] The utility model belongs to the technical field of on-site mixing vehicles, and in particular relates to an on-site mixing vehicle capable of preventing leakage. Background Art

[0002] Mine blasting is often used in mining. It improves mining efficiency by crushing the ore mountain. During the blasting process, the emulsion explosive is transported to the blasting area by the on-site mixing vehicle and poured into the blasthole through the delivery pipe. Emulsion explosive is an oil-in-water type emulsion explosive formed by the action of emulsifiers to evenly disperse the droplets of oxidant salt aqueous solution in the oil phase continuous medium containing porous substances such as dispersed bubbles or hollow glass microspheres. When the on-site mixing vehicle is loading the emulsion, the loading mechanism delivers the emulsion explosive to the tank on the on-site mixing vehicle through the delivery pipe on it.

[0003] At present, when some existing on-site mixing vehicles are filling emulsion explosives, the outlet end of the drug delivery tube is usually directly inserted into the tank mouth of the tank body on the on-site mixing vehicle. However, when the drug is discharged, the outlet of the drug delivery tube is prone to shaking and being unstable, and the drug delivery tube is affected by the reverse force of drug delivery during drug delivery, which may cause upward displacement and easy drug spillage.
