The invention discloses a forward and reverse driving device which comprises a driving rotating platform assembly, a seat and a hydraulic steering system. The driving rotating platform assembly is provided with a platform base and a rotating platform, and the rotating platform is installed on the platform base through a plane bearing. A rotating platform self-locking mechanism is further arranged between the platform base and the rotating platform and comprises a self-locking pin and a self-locking pin fixing base, and the platform base and the rotating platform can be fixed together through the self-locking pin fixing base. The hydraulic steering system mainly comprises a steering wheel, a hydraulic steering gear, an oil can, a constant flow pump, a steering change-over switch, a front axle assembly and a hydraulic steering oil cylinder. When the agricultural machine needs to adopt a forward or reverse driving mode, the orientation of the driving rotating platform assembly is manually adjusted. After adjustment, the steering function of the steering wheel is controlled according to the driving direction, a steering change-over switch is installed on the driving rotating platform, and the steering change-over switch is used for changing the hydraulic flow direction of the hydraulic steering system to achieve steering control of forward driving or reverse driving.

    本发明公开了一种正反向驾驶的装置,包括驾驶旋转平台总成,座椅,液压转向系统;驾驶旋转平台总成设有平台底座和旋转平台,旋转平台通过平面轴承安装在平台底座上;平台底座与旋转平台之间还设有旋转平台自锁机构,包括自锁销,自锁销固定座,能够将平台底座与旋转平台固定在一起。所述的液压转向系统主要包括方向盘,液压转向器,油壶,恒流泵,转向切换开关,前桥总成,液压转向油缸。当农业机械需要采用正向或反向驾驶模式时,手动调整驾驶旋转平台总成的朝向。调整后根据驾驶方向控制方向盘的转向功能,在驾驶旋转平台上安装有转向切换开关,通过转向切换开关转换液压转向系统的液压流向实现正向或反向驾驶的转向操控。
