Embodiment Construction
[0018] The present invention will be described in detail below in conjunction with the accompanying drawings, and the descriptions are all exemplary, not limiting the protection scope of the present invention.
[0019] The inventor of the present invention has carefully studied the existing plant protection machine, and found that the stroke of the hydraulic cylinder is basically the same as the lifting stroke of the working parts. Because the lifting stroke of the working parts is longer, the stroke of the hydraulic cylinder is also longer, so the hydraulic cylinder , Cylinder rods, etc. put forward higher requirements. The invention can make the stroke of the hydraulic oil cylinder shorter than the lifting stroke of the working parts, thereby reducing the cost of the hydraulic oil cylinder.

The invention discloses a machine for plant protection and a vertical lifting mechanism of the machine for the plant protection. The machine for the plant protection is provided with a work unit, the vertical lifting mechanism of the machine for the plant protection comprises a chassis structure, a power device, one or more pulleys, a lifting frame structure, one or more cable structures corresponding to the one or more pulleys, and a work unit connecting structure, and the pulleys are fixedly installed on the lifting frame structure; the chassis structure is connected with one end of each cable structure; the other end of each cable structure bypasses the corresponding pulley to be connected with the work unit connecting structure; the lifting frame structure is connected with a power rod of the power device, and thus the lifting frame structure can move up and down relative to the chassis structure driven by the power rod; the work unit connecting structure can be connected with the work unit, and thus the work unit is driven to move up and down relative to the chassis structure.
Description
technical field [0001] The technical proposal relates to a plant protection machine. Background technique [0002] With the development of modern agriculture, agricultural production is developing in the direction of refinement and high technology. The self-propelled plant protection machine is a plant protection machine developed with modern fine agricultural operations. It plays an important role in crop management and can be widely used in water spraying after sowing, herbicide spraying, insecticide and disease resistance drug spraying, leaf All aspects of the spraying of surface fertilizer. In recent years, the mechanization level of agricultural plowing, sowing, and harvesting in my country has been significantly improved. With the expansion of the scale of agricultural operations and the adjustment of the planting structure in my country, the market demand for plant protection machinery is gradually increasing. [0003] At present, the lifting mechanism of the workin...
