The invention discloses a rotary box step device for a walking board of a cab of a combine harvester, which comprises a base and a rotary box step, the rotary box step is rotatably mounted on the base and can move between a folding position and at least one unfolding position, a hinge joint is arranged on the base, and the hinge joint is connected with the rotary box step. A supporting hinging piece matched with the hinging head is arranged on the rotating vehicle ladder, and at least two lock holes are formed in the side face, facing the rotating vehicle ladder, of the hinging head; the lock holes correspond to the folding position and the unfolding position of the rotary vehicle ladder respectively. The device meets the safety requirement of the cab box step when the combine harvester runs on a road. An operator can reliably and effectively store the vehicle ladder on the ground and on a cab platform. And in the harvesting operation process, the box step cannot become the outermost end of the whole machine to be in contact with plants on the left side, and farmers are prevented from being damaged.

    本发明公开一种联合收割机驾驶室走台用旋转车梯装置,包括基座和旋转车梯,旋转车梯可转动式安装在基座上,所述旋转车梯在一收起位置和至少一个展开位置之间可活动,所述基座上设置有铰接头,所述旋转车梯上设置有与铰接头配合的支撑铰接件,所述铰接头面向旋转车梯的侧面上设置有至少两个锁孔;锁孔分别对应旋转车梯的收起位置和展开位置。本装置满足驾驶室车梯在联合收割机道路行驶中的安全性要求。操作者在地面及驾驶室平台均可对车梯进行可靠有效的收纳。而且在收获作业过程中,车梯不会成为整机最外端造成与左侧的植株碰触,避免农户均遭受损失。
