中文摘要:以变量喷洒全射流喷头为研究对象,对正方形和三角形喷洒域分别进行了水力性能试验,测量并分析了喷头的射程和喷灌强度等性能参数。结果表明:三角形比正方形喷洒域最大射程有所降低;三角形和正方形喷洒域水量分布相对均匀;变量喷洒喷头与传统全射流喷头相比,雨滴粒径相差较小;三角形与正方形喷洒域喷头平均喷灌强度相差较小,三角形喷洒域喷头的最大喷灌强度相对平均喷灌强度差值较大。变量喷洒全射流喷头比全射流喷头,组合间距增大、重叠率降低,且单位面积所用喷头数量减少。在组合间距系数为1.25,室外风速小于1.2 m/s情况下,正方形组合喷洒具有良好的喷洒均匀性。

Abstract:The hydraulic performance test of variable sprinkler were carried out for square and triangle spraying field, the wetted radius and water application rate of the sprinkler were measured and analyzed. The results showed that the maximum wetted radius of triangle spraying field was reduced than a square spraying field. The water distribution of triangle and square spraying fields were uniform relatively. Compared with the complete fluidic sprinkler, the difference of droplet size of variable sprinkler was smaller; the average application rate difference between the triangle and square spraying field was small. The maximum application rate was larger than the average application rate of triangle spraying field. The combination spacing increased, the overlap rate and number of variable sprinkler per acre were reduced. The uniformity was good for square spraying combination at the conditions of spacing factor was 1.25 and the wind speed of field was less than 1.2 m/s. The variable sprinkler operation was reliable and applied after the assessment of the natural environment. 

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
