when the mowing device needs to be lifted, electric push rods 1-3 positioned at two sides of the mowing device extend to push a connecting rod 1-1, the connecting rod 1-1 is connected with an articulated piece 1-5 through an articulated shaft 1-4, so that the articulated piece 1-5 rotates on a vehicle frame 2, the connecting rod 1-1 rotates along a middle articulated point 1-12, the connecting rod 1-2 is also driven to move forwards while the connecting rod 1-1 rotates, and then the other connecting rod 1-1 is driven to rotate around the middle articulated point 1-12, so that the two connecting rods 1-1 synchronously rotate, the frame 5 gradually lifts under the rotation of the lower articulated point 1-13, the height of a cutting knife 6 is adjusted, and the mowing device is lifted; when the mowing device needs to be lowered, the electric push rod 1-3 contracts reversely, so that the two connecting rods 1-1 rotate reversely along with the hinge parts 1-5 at the same time, and the mowing device is lowered; because the two groups of height adjusting devices 1 are distributed on the two sides of the mowing device, the electric push rods 1-3 on the two sides of the rack 5 are respectively and independently controlled, when the electric push rod 1-3 on one side is driven, one side of the mowing device is lifted up under the action of the long round holes 1-41, and the angle of the mowing device can be adjusted; when the mower encounters complex terrains (such as ramps and ditches), the heights of the two sides of the mowing device can be independently adjusted, so that the cutting knife 6 can freely incline towards the two sides, the height and the angle of the cutting knife 6 can be flexibly adjusted according to the complex terrain degree, and the mowing effect is improved.
The present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents and are included in the scope of the present invention.
