Description
技术领域technical field
本发明涉及一种智能多功能喷雾机底盘，属于植保机械技术领域。The invention relates to an intelligent multifunctional sprayer chassis, which belongs to the technical field of plant protection machinery.
背景技术Background technique
随着人们对环境保护和动植物产品安全的重视，世界各国对农药的使用都做出了不同程度的限制，农药使用技术不断向低量、精确、智能的方向发展，以确保农药在限制的用量范围内发挥出最大的效用。农药使用安全法律更加强调对农药使用者的安全保护，减少人与农药直接接触的机会，这些要求促进了植保机械智能化技术的发展。我国农作物种植面积居世界前列，但农产品的产量却远远落后于发达国家，农药残留超标事情经常发生。其中主要原因之一就是农作物在种植与生长过程中，传统植保机械作业效率低、性能差，不少地区仍停留在大容量、大雾滴喷雾技术水平上。国内外诸多学者对农药使用技术进行了大量的研究，研发了很多先进的施药技术，比如超低量喷雾、静电喷雾、智能对靶喷雾、可变量化喷雾、航空无人机喷雾等，不少科研单位研发了相关植保装备，比如悬挂式超低量弥雾机、喷杆喷雾机、轴流风送式微量静电喷雾机、自动对靶喷雾机、高射程风送式喷雾机、喷杆变换系统等，但是与这些喷雾装置配套的动力底盘的研究相对较少，目前，国内外主要采取轮式或履带式拖拉机牵引、悬挂或车载方式承载喷雾装置，尤以悬挂式居多，也有一些学者研发了一些专用底盘，但是，这些底盘总体柔性较差，难以满足复杂地形地貌对底盘通过性的需要，另外，不同作物及作物不同生长期、不同行距的植物保护需求也对底盘地隙高度及轮距的调整提出了要求，规格各异的泵、药箱以及喷杆在底盘上的合理安装也对底盘的柔性化提出了更高的需求，而目前喷雾机底盘的操纵性、舒适性以及路面运输状态时的平顺性和安全性也不够理想。With people's emphasis on environmental protection and the safety of animal and plant products, countries around the world have restricted the use of pesticides to varying degrees. Maximum effectiveness within the dosage range. The pesticide use safety law puts more emphasis on the safety protection of pesticide users and reduces the chance of direct contact between people and pesticides. These requirements have promoted the development of intelligent technology for plant protection machinery. my country's crop planting area ranks among the top in the world, but the output of agricultural products lags far behind developed countries, and incidents of excessive pesticide residues often occur. One of the main reasons is that during the planting and growth of crops, traditional plant protection machinery has low efficiency and poor performance, and many areas still remain at the level of large-capacity, large-droplet spraying technology. Many scholars at home and abroad have conducted a lot of research on pesticide application technology, and developed many advanced pesticide application technologies, such as ultra-low volume spray, electrostatic spray, intelligent target spray, variable quantification spray, aerial drone spray, etc. A few scientific research units have developed related plant protection equipment, such as hanging ultra-low-volume mist misting machines, boom sprayers, axial-flow air-fed micro-electrostatic sprayers, automatic target sprayers, high-range air-fed sprayers, and spray booms. Transformation system, etc., but there are relatively few studies on the power chassis supporting these spray devices. At present, wheeled or crawler tractors are mainly used to carry spray devices at home and abroad, suspended or vehicle-mounted, especially the suspended type, and some scholars Some special chassis have been developed. However, these chassis are generally less flexible, and it is difficult to meet the needs of complex terrain and landforms for the passability of the chassis. In addition, the plant protection requirements of different crops and crops in different growth periods and different row spacing also affect the chassis. The adjustment of the wheelbase puts forward requirements, and the reasonable installation of pumps, medicine boxes and spray bars with different specifications on the chassis also puts forward higher requirements for the flexibility of the chassis. The ride comfort and safety during road transportation are not ideal either.
