Background technique

In the control measures of plant diseases and insect pests, the effect of pesticide control is good, especially in the control of large-scale plant diseases and insect pests. Therefore, chemical control still occupies the main position in the field of plant protection. At present, agriculture is developing in the direction of modernization, scale, production intensification, and agricultural machinery specialization. In particular, socialized agricultural machinery service cooperatives have become the mainstream of agricultural machinery development in my country. In the development of specialized plant protection machinery in my country, there are three mainstream spraying methods. The boom sprayer is mainly used for the control of plant diseases and insect pests of field crops, and the tunnel sprayer is mainly used for the plant protection of horticultural crops cultivated by hedges. The imitation form The sprayer is mainly used for profiling spraying in orchards. The above-mentioned special spraying machinery still has problems such as single function, strong seasonality of machine use frequency and low annual use efficiency in the face of numerous crop pest control. Especially in most of the agricultural areas where the small-field production mode dominates in my country, different crop cultivation methods require different operation forms.

Aiming at the above-mentioned problems such as the single spraying function of the traditional spraying agricultural machinery, the large difference in the spraying effect due to different configurations of the machinery, the inability to realize the multi-functional reuse of the machinery, and the high purchase cost of the whole, a kind of agricultural machinery with high annual utilization rate, multi-purpose, and high annual utilization rate was invented. Plant protection machinery that can adapt to the requirements of different working environments and ensure the spray effect has important practical significance.

After searching the prior art literature, it was found that the Chinese invention patent "Room Sprayer and Its Sprayer Changing Method", application number 201010132576.5, provides a sprayer type sprayer and its method of changing the boom. The mechanism enables the spray bar to be changed into "door" type and "one" type spray, and its spray area can be adjusted according to the change of row spacing, and at the same time, the airflow blown by the flexible air curtain tube is used to force the spray droplets to the plants. Chinese invention patent "Sprayer Spray Boom Transformation Method and Its Mechanism", application number 201010132553.4, provides a sprayer spray boom transformation method and its mechanism, by adjusting the lateral position of the side spray booms on both sides of the fixed spray boom , the installation position of the side spray bar and the vertical spray bar and the installation position or length of the adjustment support rod connected between the side spray bar and the vertical spray bar to form a nozzle pipe with a dynamic shape change.
