Underground on-site explosive dosing and charging truck

The invention relates to the technical field of underground explosive trucks and discloses an underground on-site explosive dosing and charging truck. The underground on-site explosive dosing and charging truck comprises a truck body, a chassis disposed on the truck body, a mechanical arm automatic hole finding mechanism and a charging conveying mixing mechanism which are disposed on the chassis, and a hydraulic system and an electric control system which are matched with the mechanical arm automatic hole finding mechanism and the charging conveying mixing mechanism, wherein the charging conveying mixing mechanism comprises an automatic charging module used for mixing and charging emulsion matrix to form emulsion explosives, a charging tube which is connected with the automatic charging module and used for conveying the emulsion explosives, and an automatic tube conveyor for automatically conveying the charging tube; the mechanical arm automatic hole finding mechanism is matched with the automatic tube conveyor and used for performing blast hole position alignment on the head end of the charging tube. The underground on-site explosive dosing and charging truck has the advantages that mechanical hole finding, automatic tube collecting and conveying and automatic blast hole filling are achieved, charging efficiency is increased, operator labor intensity is lowered, and operator safety conditions are improved effectively.
