The invention relates to the technical field of unmanned driving, and discloses a steering device for agricultural machinery unmanned driving and a steering method thereof.The steering device comprises a steering assembly, the steering assembly comprises a fixing plate, a first supporting rod is fixedly connected to the bottom of the fixing plate, and a second supporting rod is fixedly connected to the outer surface of the first supporting rod; an electric push-pull rod is started to drive a first pressing plate to move leftwards or rightwards so as to stretch and extrude hydraulic oil in an oil storage rod, however, due to blocking of two first springs, a first sliding frame is difficult to move, at the moment, the first pressing plate moves to drive the oil storage rod to move, and then a steering wheel is driven to rotate for steering; when the steering wheel is blocked by an obstacle and cannot rotate, an electric push-pull rod drives a first pressing plate to continue to move, the first pressing plate can drive a first sliding frame to move through hydraulic oil and compress and stretch two first springs correspondingly, and by means of the design, when the steering wheel is clamped, the first sliding frame can be driven to move through hydraulic oil; and damage to the device caused by continuous steering force application of the electric push-pull rod is prevented.
本发明涉及无人驾驶技术领域,且公开了一种农业机械无人驾驶用的转向装置及其转向方法,包括转向组件,转向组件包括固定板,固定板底部固定连接有支撑杆一,支撑杆一外表面固定连接有支撑杆二,本发明启动电动推拉杆带动压板一向左或向右侧移动,以对储油杆内部的液压油进行拉伸和挤压,但由于两个弹簧一的阻挡,滑动架一难以进行移动,此时压板一移动会带动储油杆进行移动,进而带动转向轮进行转动以进行转向,当转向轮被障碍物阻挡而无法进行转动时,随着电动推拉杆带动压板一继续进行移动,压板一会通过液压油带动滑动架一进行移动并分别压缩和拉伸两个弹簧一,此种设计可在转向轮被卡住时,防止电动推拉杆持续施加转向力对装置造成损坏。
