Problems solved by technology
However, the wire rope lifting mechanism currently used in agricultural machinery has problems such as poor motion stability and low lifting height; at the same time, due to the limitation of the lifting mechanism, the terrain imitation ability of the operating device on agricultural machinery is not ideal, which in turn affects the operation effect. A kind of wire rope hoisting mechanism described in CN110800435A, its hoisting operation device height is low, causes the operation device to easily touch the ground when the operation machine is walking on a slope, and then damages the operation device; Move left and right, which greatly affects the operation effect

Description
technical field [0001] The invention discloses a terrain-imitating vertical lifting mechanism of an operating device, which relates to the field of mechanical technology. Background technique [0002] As a lifting device, the lifting mechanism has been widely used in agricultural machinery, construction machinery and other fields. Lifting mechanisms can be divided into rigid lifting mechanisms, flexible lifting mechanisms and rigid-flexible dual-attribute lifting mechanisms according to different attributes. Among them, the wire rope lifting mechanism in the flexible lifting mechanism is widely used because of its flexible layout, low operating noise, and stable operation. However, the wire rope lifting mechanism currently used in agricultural machinery has problems such as poor motion stability and low lifting height; at the same time, due to the limitation of the lifting mechanism, the terrain imitation ability of the operating device on agricultural machinery is not idea...
