Suction cover of emulsion explosive on-site mixed loading truck

The utility model discloses a suction hood for an emulsion explosive on-site mixed loading truck, which relates to the technical field of suction hoods and comprises a truck hopper, a bottom plate is arranged on the upper side of the truck hopper, a first suction hood and a support plate are fixedly connected to the surface of the bottom plate, a second suction hood is slidably connected to the inner side of the first suction hood, and the support plate is fixedly connected to the inner side of the second suction hood. According to the material suction cover of the emulsion explosive on-site mixed loading truck, a butt joint plate on the third material suction cover enters the forehead inner wall of a butt joint groove to form butt joint at the moment, and in this way, the defect that dust flies when a traditional open-air truck hopper is used for loading emulsion explosives is overcome; and the defect that dust cannot be effectively shielded when a traditional car hopper carries out butt joint shielding thro
