The lower bottom of the lower side panel 13 of the side plate 4 is welded with a locking hook stop 14. The locking hook stop 14 blocks or separates from the locking hook 17 to open and close the locking hook, so as to provide a bulk cargo unloading channel. The corner pieces 8 for the standard container are welded on the front and rear end plates 3 to provide a point to be hoisted and dumped.
[37] After placing the self-unloading open top container for road-rail combined transportation according to the present disclose on a conventional container semi-trailer or on a railway container flat car, rotate a rotary lock head of a frame vehicle for locking and fixing the container thereon. After the shipment reaches the unloading site, through an air path or a hydraulic control pipeline, the pneumatic cylinder or the second hydraulic cylinder 18 is pushed to rotate the locking hook 17 outward about the locking hook seat 19. The lower side panel 13 of the side plate is opened. By means of the control pipeline for the first hydraulic cylinder, the first hydraulic cylinder 9 is lifted and extended. The bottom plate 5 is driven by the hydraulic cylinder hinge seat 15 so as to rotate and turn around the hinge assembly 7 on the outer side stringers of the turnover bottom frames. The bulk cargo slides out of the container under its own weight, implementing unloading.
