The lower-layer chassis welding part comprises longitudinal beams arranged at intervals, a front cross beam connected with the first ends of the longitudinal beams, a rear cross beam connected with the second ends of the longitudinal beams and an engine mounting frame arranged on the rear cross beam, and the top face of the engine mounting frame is lower than the top faces of the longitudinal beams. The frame-type chassis is small in material consumption, compact in overall structure and convenient to machine, meanwhile, the frame-type structure can effectively reduce the area of the welded top face of the lower-layer chassis, accumulation of sundries is reduced, scratching of working parts on the chassis due to the accumulation of the sundries is avoided, and the service life of the working parts is prolonged; by lowering the position of the engine mounting frame, the overall gravity center is lower than the upper plane of the lower-layer chassis welding, the gravity center position of the whole machine can be effectively lowered, the transverse stability of the vehicle is improved, and a good foundation is provided for high-speed and efficient field operation.
本发明公开了一种下层底盘焊合、底盘及番茄收获机,包括间隔布设的纵梁、与所述纵梁的第一端连接的前横梁、与所述纵梁的第二端连接的后横梁、布设于所述后横梁上的发动机安装架,所述发动机安装架的顶面低于所述纵梁的顶面,其材料的使用少,整体结构紧凑,加工方便,同时,框架式的结构能有效降低下层底盘焊合顶面的面积,减少了杂物的累积,避免底盘之上的工作部件因杂物累积产生剐蹭,延长工作部件的使用寿命;通过降低发动机安装架的位置,使得整体的重心低于下层底盘焊合的上平面,可以有效的降低整机的重心位置,提高车辆的横向稳定性,为高速高效的田间作业提供了良好的基础。
