[0002] When bagged fertilizers are packaged and produced, the packaging belt must be filled with fertilizers on the production line first, and then the packaging bags are sewn and sealed. At this time, the bagged fertilizers are located on the first conveyor belt device 1 and are in an upright state. When entering the second conveyor belt device 7, the upright bagged fertilizers need to be shifted and laid flat for subsequent palletizing. The shifting device currently used is roughly the same as the gantry-type bag-pushing mechanism disclosed in CN212387240U. When used, refer to the attached figure in CN212387240U.
