Description

technical field [0001] The invention relates to a frame of a self-propelled sprayer in the field of agricultural machinery, in particular to a frame of a self-propelled four-wheel boom sprayer with a high ground clearance. Background technique [0002] As the country attaches great importance to agricultural production, the problems of agricultural modernization and development are prominently placed in front of us. In the past few years, our country has mainly focused on the development of equipment for cultivation and autumn harvesting, while the protection equipment for the medium-term plant growth stage, that is, plant protection machinery, lags behind compared with the other two aspects. In the past two years, the state has begun to increase policy subsidies for agricultural machinery. At the same time, related companies have also begun to increase research and development of large-scale plant protection machinery. At present, there is no good large-scale plant protecti...
