Abstract: In view of the serious problems of the traditional gasoline lawn mower, such as serious noise and air pollution, high manpower cost, and inconvenient operation, etc., a type of intelligent grassland maintenance equipment suitable for various pruning conditions and can perform auxiliary irrigation and other operations is proposed in this paper, which is suitable for standard lawn maintenance work in parks, schools and private gardens, etc. Focusing on the structural design of each component mechanism of grassland maintenance equipment, a light lifting mechanism is used to adjust the working height, and an independent suspension is set to maintain certain stability in the work, and the gear pump is used for uniform spraying. Through simulation analysis of the key components in the working process, it is verified that the overall design of the equipment has the advantages of intelligence, automation, high efficiency, perfect functions, and environmental protection. The correctness and working reliability of the equipment design are also verified. It has certain reference value for research and development of the grassland maintenance equipment.
