[0042] More specifically, in this embodiment, a fluidizing device is further provided at the rear of the discharge hopper, and the fluidizing device includes an air supply member, and the air supply member is used to supply air into the discharge hopper.

[0043] More specifically, in addition to supplying air into the tank body 1 through the air supply part of the fluidizing device, air is also supplied into the tank body 1 through other means to quickly increase the pressure in the tank body 1. For this purpose, the rear-flip tank vehicle further includes an air supply device, which is connected to the fluidizing device and is also connected to an air supply pipe for supplying air to the tank body 1. That is, air is supplied into the tank body 1 through the fluidizing device and the air supply pipe respectively, and the air supply device is generally an air compressor.

[0044] Specifically, in this embodiment, the fluidization device includes a blowing aid 5, that is, the blowing aid 5 is arranged at the rear of the discharge hopper, and the blowing aid 5 realizes the fluidization of the material when blowing air toward the rear of the discharge hopper.
