When the tipping machine is vertical and the container door 400 is facing upward, by starting the oil cylinder 1 240, the output end of the oil cylinder 1 240 is extended at a uniform speed, and the extended oil cylinder 1 240 and the pin shaft 3 241 are used together to push the crank arm 230 to rotate to the appropriate position. The crank arm 230 deflected to the appropriate position makes the connecting rod 350 droop naturally, and the cross-piece 360 ​​begins to gradually unfold under the pull of the pull rope 370, so that the cross-piece 360 ​​is obliquely attached to the container door 400, and the cross-piece 360 ​​is between the two long round rods of the container door 400. By starting the connecting rod 35 0 is extended, and the extended connecting rod 350 is used to push the connecting arm 330 to swing, so that the rotating pin 340 and the connecting rod 350 are rotated, and then the cross-piece 360 ​​is rotated, and the rotated cross-piece 360 ​​is perpendicular to the two long round rods on the container door 400, and the two V-shaped ends of the cross-piece 360 ​​are aligned with the two long round rods on the container door 400, and then the cylinder 240 is started to shrink, so that the crank arm 230 is reset, so as to facilitate opening the container door 400. When the box tipping machine completes receiving the materials, the cylinder 240 is started to extend to facilitate closing the container door 400, and the connecting rod 350 is started to shrink, so as to reset the connecting mechanism 300, so as to facilitate folding the container automatic door closing mechanism for standby.
