3WZ-700型果园喷雾机通过性能分析

Analysis on Trafficability of 3WZ-700 Orchard Sprayer

针对现代果园低矮密植的园艺特征和果园喷雾机重心动态变化特点,通过试验和建立数学模型对大容量药箱的果园喷雾机的通过性能进行分析,得出药量与越障高度的关系曲线。在0～200 L药量区间内前轮越障由200 mm下降到84 mm;在200～400 L药量区间内前轮越障高度随药量变化缓慢,由84 mm下降到53 mm;后轮越障高度与喷雾机参数无关。实地测试表明,试验均值与理论值基本一致,喷雾机通过性能较好。

According to modern orchard planting pattern and dynamic center of gravity of orchard sprayer, a mathematical model was established by theoretical calculation and test. The trafficability of large carton orchard sprayer was analyzed. The obstacle height curve with dosage was obtained. In the dosage range of 0 -200 L, the front wheels crossed obstacles reduced from the 200 mm to 84 mm. In the dosage range of 200 -400 L, the front wheels crossed obstacles reduced from the 84 mm to 53 mm. Rear wheel obstacle height was independent of machine parameters. Experimental were consistent with theoretical calculations. The results showed that the sprayer had outstanding trafficability in orchard.
