The invention discloses a lifting chassis and a field operation vehicle, and belongs to the field of agricultural machinery. The actual situation of field operation is considered, and the ground clearance of a walking chassis can be kept larger than the height of crops. The lifting chassis comprises a rack, a cross beam, walking wheels, a chassis frame and a plurality of shear fork mechanisms, wherein the walking wheels are installed on the cross beam, a linear driving unit is installed between the rack and the cross beam, the bottom ends of the shear fork mechanisms are installed on oppositeside beams of the rack, and the numbers of the shear fork mechanisms installed on the opposite side beams are equal; and a guide rod is connected to a portion between the opposite side beam shear forkmechanisms located on the rack, the top ends of the shear fork mechanisms are connected with the chassis frame, and the shear fork mechanisms can move synchronously to drive the chassis frame to movein the vertical direction relative to the rack.
本发明公开了一种升降底盘及田间作业车辆,属于农业机械领域,考虑田间作业的实际情况,能够保持行走底盘的离地间隙要大于作物高度,其中升降底盘包括机架、横梁、行走轮、底盘架和多个剪叉机构,行走轮安装于横梁,机架和横梁之间安装直线驱动单元,剪叉机构的底端安装在机架的相对的侧梁,且相对的侧梁安装的剪叉机构的数量相等;位于机架的相对的侧梁剪叉机构之间连接有导杆,多个剪叉机构的顶端连接底盘架,多个剪叉机构能够同步运动以带动底盘架相对于机架在垂直方向移动。
