    • An agricultural machine comprises a chassis (1) and a device for displacing a working organ (9) along the surface of the field, which contains a hermetic chamber (3) with a window (4), a source of a fluid agent pumped into the chamber (3) under pressure and a flexible sleeve (7) which is wound on a drum (5) and which contains a traction element (8) inside it. A device which carries the working organ (9) is mounted on a section of the traction element (8) coming out at the loose end of the sleeve (7) and is movably connected to the flexible sleeve (7). The loose end of the sieeve (7) passes through the chamber (3), is turned inside out and hermetically fixed in the window (4) of the chamber (3). The annular cavity thus created (A) is connected to the chamber (3) and under the influence of the fluid agent changes its volume and displaces along the field the sleeve (7) which pushes in front of it the device carrying the working organ (9).
    • 一种农业机械包括底盘(1)和用于沿着田地表面移动工作元件(9)的装置,该装置包括具有窗口(4)的密封室(3),泵送入的流体源 在压力下的腔室(3)和缠绕在滚筒(5)上并且在其中包含牵引元件(8)的柔性套筒(7)。 承载工作机构(9)的装置安装在牵引元件(8)的在套筒(7)的松散端处伸出的区段上并且可移动地连接到柔性套筒(7)。 筛(7)的松散的端部穿过室(3),翻出并密封地固定在室(3)的窗口(4)中。 由此形成的环形空腔(A)连接到腔室(3),并且在流体制剂的影响下改变其体积并且沿着现场移动套管(7),该套管在其前面推动携带工作器官的装置 9)。
