In the process of field plant protection and spraying operations, farmers mainly face the following pain points: Firstly, the large area to be controlled and tight timeframes make traditional manual operations or small-scale plant protection methods inefficient, making it difficult to complete plant protection work within the optimal time window. Secondly, some fields adopt a paddy-upland rotation model with numerous drainage ditches and significant roughness , imposing high requirements on the overall machine's passability and boom stability. Additionally, many fields are far apart, requiring frequent transfer operations. A faster machine transfer speed can save transfer time, increase actual spraying time, and improve control efficiency. Thirdly, uneven pesticide mixing and inconsistent droplet concentration lead to poor control effects, as well as pesticide waste and even phytotoxicity. Fourthly, long-term operation can cause the machine to overheat and run out of fuel, resulting in frequent shutdowns that affect efficiency. Therefore, choosing a plant protection sprayer that can address these pain points requires careful consideration.
Based on the operational needs of field plant protection, the following key points cannot be ignored, as they directly determine the machine's operational efficiency, effectiveness, and user experience:
1.Power Performance and Manoeuvrability: Meeting the Needs of Long-Term and Complex Road Conditions
Plant protection operations are time-sensitive and demanding, requiring the sprayer to have strong power and stable performance. It is advisable to choose models equipped with branded diesel engines, while paying attention to the rationality and stability of the power system matching. For example, a dual-pump structure can enhance manoeuvrability and reduce failure rates, ensuring that the boom system maintains balance when the equipment operates on complex plots, slopes, and other terrains. It also allows for real-time adjustment of the relative distance between the boom and crops, avoiding boom damage from touching the ground or pesticide drift.
2.Endurance and Heat Dissipation: Ensuring Uninterrupted Continuous Operation
Long-term operation places high demands on the equipment's endurance and heat dissipation capabilities. When purchasing, it is necessary to pay attention to the fuel tank capacity; models with a large fuel tank of 50 liters or more are recommended to meet the demand for continuous operation of more than 10 hours. At the same time, equipment with an enlarged and thickened radiating water tank, combined with a dust-proof mesh cover, can avoid overheating failures and adapt to complex operating environments.
3.Spraying Effect: Uniform and Efficient, Improving Pesticide Utilization Rate
The uniformity of pesticides, as well as the penetration and adhesion of droplets, directly affect the control effect. High-quality plant protection sprayers should be equipped with large-capacity chemical tanks, paired with a scientific mixing system (such as a return water + jet mixing function) to ensure uniform pesticide mixing. Choosing a spraying pump with high pressure and good atomization, such as a Taiwan-quality three-cylinder plunger pump, can enhance droplet penetration and adhesion, ensuring uniform spraying, and improving pesticide utilization rate and control effect.
