Cargo discharging mechanism allowing cargos to perpendicularly fall and using method of cargo discharging mechanism

The invention relates to a cargo discharging mechanism allowing cargos to perpendicularly fall and a using method of the cargo discharging mechanism. The cargo discharging mechanism comprises a rack, a cargo storage area used for perpendicularly stacking the cargos is arranged inside the rack, a horizontal sliding mechanism which can be driven by an electric mechanism to carry out longitudinal reciprocating sliding movement relative to the rack is arranged below the cargo storage area, a perpendicular sliding mechanism which is driven by the horizontal sliding mechanism and can carry out vertical reciprocating sliding movement is vertically arranged on the longitudinal end side of the cargo storage area, and supporting plates which are driven by the perpendicular sliding mechanism and used for supporting the cargos on the bottom layer and clamping plates used for clamping the cargos on the penult layer are arranged in the cargo storage area. According to the mechanism, the perpendicular sliding mechanism is driven through driving grooves, then the clamping plates and the supporting plates are driven to synchronously and stably run through a clamping plate driving cavity and a supporting plate driving cavity of the perpendicular sliding mechanism, and thus cargo discharging is stable and reliable; before the cargoes are discharged, wheels A are located on a horizontal section B, so that the bearing capability of the mechanism is large, the cargo storage quality is large, and safety and reliability are achieved; the influence of damage to the mechanism by the falling impact of the stacked cargoes is reduced.
