The invention discloses a scissor type agricultural chassis with adjustable wheel tread and chassis height and a working method thereof. According to the chassis device, two platform plates are horizontally arranged in a crossed mode, the two platform plates are hinged through a first hinge shaft and driven by a stepping motor to be opened and closed, the two ends of each platform plate are each provided with a first assembly composed of an electric cylinder, a steering motor, a connecting frame and a walking mechanism, and piston rods of the electric cylinders in the first assemblies are fixed to the platform plates; a cylinder body of the electric cylinder is fixed to one end of the connecting frame, a shell of the steering motor is fixed to the other end of the connecting frame, and an output shaft of the steering motor drives the walking mechanism to rotate. The multiple chassis devices are arranged in an array mode. The corresponding platform plates are driven to ascend and descend through the piston rods of the electric cylinders, then height adjustment is achieved, the two platform plates are driven to be opened and closed through the stepping motors, each platform plate drives the two walking mechanisms to move, and therefore wheel track adjustment is achieved.
本发明公开了一种轮距和底盘高度可调的剪刀式农用底盘及其工作方法。本发明的底盘装置中平台板设有水平交叉设置的两块,两块平台板通过铰接轴一铰接,并由步进电机驱动开合,每块平台板的两端均设有由电动缸、转向电机、连接架和行走机构组成的组件一,组件一中电动缸的活塞杆与平台板固定,电动缸的缸体与连接架的一端固定,转向电机的壳体与连接架的另一端固定,转向电机的输出轴驱动行走机构转动;底盘装置设有呈阵列式排布的多个。本发明通过电动缸的活塞杆驱动相应的平台板升降,进而实现高度的调节,并通过步进电机驱动两块平台板开合,每块平台板带动两个行走机构运动,从而实现轮距的调节。
