Air Tractor Spraying Systems and Spraying Technology

摘要:

摘要：空中拖拉机是当前我国农化作业效率最高的飞机之一。其先进的喷雾系统由药箱、高压泵、喷杆、喷头、加药设备及控制系统等部分组成。空中拖拉机飞行高度在平原和山区分别为树梢以上10～15m和20m以上，AT-504和AT-402B的有效喷幅分别为80m和60m。大多数雾滴直径100～200μm，雾化程度高，可以通过改变喷头角度来调整雾滴密度和大小。

Abstract:

Abstracts:The Air tractor is one of the highest efficiency agricultural air sprayer in China at present .Its spraying system is advanced, which consists of kits, high pressure pump, booms, nozzles, dosing equipment and control systems. Its altitude of the plains and mountains were 10~15 m above the treetops and more than 20 m, effective spray to increase the AT-504 and AT-402B, respectively 80 m and 60 m. Most of droplet diameter of 100~200 μm.Degree of atomization is good.The droplet density and size can be adjusted by changing the nozzles angle.
