Description
技术领域technical field
本发明涉及植保设备技术领域，更具体的说是涉及一种外混式双流体扇形雾喷头。The invention relates to the technical field of plant protection equipment, and more specifically relates to an external mixing two-fluid fan-shaped spray head.
背景技术Background technique
目前，生物农药因其环境友好、无化学残留、可持续控制等优点，在农林病虫害防治中具有重要的发展潜力，已逐渐成为研究热点和重要方向。At present, due to the advantages of environmental friendliness, no chemical residues, and sustainable control, biopesticides have important development potential in the control of agricultural and forestry diseases and insect pests, and have gradually become a research hotspot and an important direction.
但是，生物农药施药技术落后、利用率低已成为限制其发展的关键问题。与化学农药不同，生物农药是具有活性的系统，为了保持药效，不仅要对施药时的药液雾化性能有严格要求，而且需保证农药内细菌的数量和活性，但目前国内尚无专门用于生物农药的施药机械，无法确保施药时生物农药活性。However, the backward application technology and low utilization rate of biopesticides have become the key problems restricting their development. Different from chemical pesticides, biological pesticides are active systems. In order to maintain the efficacy, not only must there be strict requirements on the atomization performance of the chemical solution during application, but also the number and activity of bacteria in the pesticide must be guaranteed. However, there is currently no such system in China. The spraying machinery specially used for biopesticides cannot ensure the activity of biopesticides during application.
在施药机械各部件中，喷头是决定农药雾化性能的关键性部件，也是造成生物农药活性成分损伤的关键部件。原因是生物农药在流经喷头雾化时，一是农药内的活体细胞与喷头内壁发生碰撞、冲击，二是雾化时产生的液体拉应力和剪切应力等液体应力，二者均会加剧农药内的活体细胞损伤，造成生物农药活性降低。Among the components of pesticide application machinery, the nozzle is the key component that determines the atomization performance of pesticides, and is also the key component that causes damage to the active ingredients of biopesticides. The reason is that when the biopesticide flows through the nozzle and is atomized, first, the living cells in the pesticide collide and impact with the inner wall of the nozzle, and second, the liquid stress such as liquid tensile stress and shear stress generated during atomization, both of which will intensify The living cells in the pesticide are damaged, resulting in a reduction in the activity of the biopesticide.
现有雾喷头有圆锥雾喷头和扇形雾喷头，扇形雾喷头球头结构相比于圆锥雾喷头，虽然对生物制剂的活性伤害较大，但扇形雾喷头喷射范围广，并且因其独特的雾型分布，在大型喷雾机上多喷头组合喷施时具有不可替代的作用。Existing mist nozzles include conical mist nozzles and fan-shaped mist nozzles. Compared with conical mist nozzles, the ball head structure of fan-shaped mist nozzles has greater damage to the activity of biological agents, but fan-shaped mist nozzles have a wider range of spraying, and because of their unique fog It has an irreplaceable role in multi-nozzle combination spraying on large sprayers.
因此，如何提供一种在满足扇形雾喷头喷雾形状和雾量分布的基础上，又能减小生物农药中生物活体损伤，保证生物农药活性，以达到病虫害防治目的外混式双流体扇形雾喷头是本领域技术人员亟需解决的问题。Therefore, how to provide an externally mixed two-fluid fan-shaped mist nozzle that satisfies the spray shape and mist volume distribution of the fan-shaped mist nozzle, and can reduce the damage of living organisms in biopesticides, ensure the activity of biopesticides, and achieve the purpose of pest control. It is a problem that those skilled in the art need to solve urgently.
