When the bottommost container is stacked, the angle adjusting oil cylinder controls the first-level slide rails to slightly incline downwards (the telescopic vertical frames 202-2 on the left side and the right side are synchronous), the container arrangement platform 201 is driven to incline downwards, and the push-out height of the first-layer container is reduced. When the second layer is stacked, the angle adjusting cylinder is retracted, so that the cargo box arrangement platform 201 is in a horizontal state. Along with the increase of the packing box stacking layer number, the first-level oil cylinder continuously lifts to drive the second-level slide rail to lift, and when the second-level slide rail is lifted to the top of the first-level slide rail, the second-level oil cylinder starts to lift to drive the third-level slide rail to lift. One end of the chain 202-6 is connected with the lifting support 202-1, the other end of the chain is connected with the second-level slide rail, the middle of the chain bypasses the chain wheel 202-5, and when the third-level slide rail is lifted, the lifting support 202-1 and the container arrangement platform 201 are driven to be lifted, so that automatic stacking layer by layer is realized.
