Hydraulic stacking machine

The invention discloses a hydraulic stacking machine, comprising a to-be-stacked layer platform, a to-be-stacked layer push device, a side surface leveling device, an up-down stacked layer leveling device, an open-close plate device, an elevating device, a stacking platform device, and position acquisition photoelectric sensing devices. The stacking platform device is arranged on the elevating device. The open-close plate device is arranged on the left side and the right side of the upper part of stacking platform device lifting stroke. The up-down stacked layer leveling device is arranged on the open-close plate device. The side surface leveling device is arranged between the up-down stacked layer leveling device and the open-close plate device, and is arranged on the left side and on the right. The to-be-stacked layer platform is arranged on the rear side of the open-close plate device and is abutted against with the open-close plate device. The to-be-stacked layer push device is arranged on the to-be-stacked layer platform. The position acquisition photoelectric sensing devices are arranged on each stacking layer decline height position under the open-close plate device in a left and right symmetrical manner. The machine can level the stacking layer from a plurality of surfaces, so that stacking is in order and is beautiful and steady, and stacking layer can be stacked higher and phenomenon of stacking tilt and falling would not occur.
