Description
技术领域 technical field
本实用新型涉及一种农药喷洒系统，特别涉及一种单旋翼植保无人机用农药喷洒系统，属于农业无人机植保技术领域。 The utility model relates to a pesticide spraying system, in particular to a pesticide spraying system for a single-rotor plant protection drone, which belongs to the technical field of agricultural drone plant protection.
背景技术 Background technique
随着我国城乡一体化建设进程加快，发展规模种植已成为我国农业现代化重要举措，随着农业种植大户、家庭农场和农民合作社等新型农业生产经营主体的出现和壮大，传统的人背喷雾器打药防病治虫的植保作业方式，已经不能适应现代农业发展的要求，迫切需要高效率、低成本的现代化植保机械和施药技术。我国农业生产过程中，落后的植保机械和粗放的施药技术，导致农药利用率不高，目前仅35%左右；由于一家一户分散防治，防治不专业，用药混乱，药害现象时有发生；同时农药残留量大，对环境污染严重。病虫害发生重，危害面积大，每年因病虫害无法及时防治导致的减产在10-30%之间。对于种田大户、家庭农场和农民专业合作社等新型的农业生产经营主体，面对大面积突然爆发病虫害疫情时，在短时间很难找到大批施药人员，病虫害防治成了他们最头疼的大事。 人工打药，不仅效率低，而且对操作人员的身体伤害非常大，据统计我国每年有20万人因打农药中毒，数千人死亡。 农用低空无人施药机具有操作简单、喷洒均匀、用药量少、效率高、容易操作、便于信息化管理等特点，自2006年国家开始发展无人机航空植保施药装备与技术开始，目前出现了以多旋翼、单旋翼飞行器为飞行平台的航空植保机，但在这一领域目前存在这诸多问题，对于单旋翼航空植保无人机的喷雾系统的研究还处于初级阶段，例如关于喷头的选择、喷头安装数量与间距、喷雾系统的配置等还不规范，特别存在存在着雾滴易受旋翼气流影响的问题，造成雾滴飘失，农药对机身污染、雾滴的靶向性低、农药利用效率低且对环境污染等问题。 With the acceleration of the integration of urban and rural areas in my country, the development of large-scale planting has become an important measure for my country's agricultural modernization. The plant protection operation method of disease control and pest control can no longer meet the requirements of modern agricultural development, and there is an urgent need for high-efficiency, low-cost modern plant protection machinery and pesticide application technology. In the process of agricultural production in my country, backward plant protection machinery and extensive pesticide application technology lead to low utilization rate of pesticides, which is only about 35% at present; due to scattered control by one household, unprofessional control, chaotic use of pesticides, pesticide damage occurs from time to time ; At the same time, the amount of pesticide residues is large, which seriously pollutes the environment. The occurrence of pests and diseases is heavy, and the area of damage is large. The annual production reduction due to the failure of timely control of pests and diseases is between 10-30%. For new types of agricultural production and management entities such as large farmers, family farms, and farmers' professional cooperatives, when faced with a sudden outbreak of pests and diseases in a large area, it is difficult to find a large number of pesticide applicators in a short period of time, and pest control has become their biggest headache. Manual spraying is not only inefficient, but also very harmful to the operators. According to statistics, 200,000 people are poisoned by pesticides every year in my country, and thousands of people die. Agricultural low-altitude unmanned pesticide applicators have the characteristics of simple operation, uniform spraying, less dosage, high efficiency, easy operation, and convenient information management. Since 2006, the country began to develop drone aerial plant protection pesticide application equipment and technology. There have been aerial plant protection aircraft with multi-rotor and single-rotor aircraft as flying platforms, but there are many problems in this field. The research on the spray system of single-rotor aerial plant protection drones is still in its infancy. The selection, number and spacing of nozzle installations, and the configuration of the spray system are not standardized. In particular, there are problems that the droplets are easily affected by the rotor airflow, resulting in droplet drift, pesticide pollution to the fuselage, and low targeting of the droplets. , Low efficiency of pesticide utilization and environmental pollution.
