The invention relates to the field of agricultural machinery, and discloses a self-propelled agricultural chassis and a spraying machine with the self-propelled agricultural chassis, the self-propelled agricultural chassis comprises a swing frame beam assembly (1), and a plurality of walking wheel assemblies (2) and a frame (3) which are arranged on the swing frame beam assembly, the swing frame beam assembly (1) comprises a pair of swing frame beams (11) which are oppositely arranged in a spaced mode, a middle shaft (12) which penetrates through the swing frame beams to extend, a middle shaft left end connecting piece (13), a middle shaft right end connecting piece (14), a first wheel track adjusting push rod (15) and a second wheel track adjusting push rod (16), and the middle shaft left end connecting piece (13) and the middle shaft right end connecting piece (14) are connected to the two ends of the middle shaft respectively. The first wheel track adjusting push rod and the second wheel track adjusting push rod can stretch out and draw back so that the swing frame beams can have different intervals, and the swing frame beams can longitudinally swing around the middle shaft. When the chassis runs to an uneven road surface, the swing frame beam rotates around the middle shaft in a small range, and due to the fact that the frame connecting mechanism is hinged to the swing frame beam, and under the supporting and damping effects of the suspension, the whole frame can be kept horizontal.
本发明涉及农用机械领域,公开了一种自走式农用底盘及具有其的喷雾机,包括摆架梁组件(1)以及安装至该摆架梁组件的多个行走轮组件(2)和车架(3),其中,所述摆架梁组件(1)包括间隔相对布置的一对摆架梁(11)、穿过该摆架梁延伸的中间轴(12)、分别连接至该中间轴两端的中间轴左端连接件(13)和中间轴右端连接件(14)、第一轮距调节推杆(15)和第二轮距调节推杆(16),其中,所述第一轮距调节推杆和第二轮距调节推杆能够伸缩为使得摆架梁具有不同间距,摆架梁能够绕所述中间轴的纵向摆动。当底盘行驶至不平路面,摆架梁绕中间轴小幅度转动,由于车架连接机构铰接至摆架梁,同时在悬架的支撑减震作用下,可保持该车架整体水平。
