Abstract:On the basis of analyzing the relationship between pressure before the nozzle and nozzle area, radius of throw, a new type of variable-rate sprinkler was developed by using activity pieces and non-circle nozzle device on an impact sprinkler. The structure and working principles were presented. Experiment of hydraulic performances was conducted and analyzed. The water distribution isoline of single nozzle was plotted by using Matlab. Results showed that the variable-rate sprinkler with non-circle nozzle was able to operate reliably, and the triangle wetted area and square wetted area was obtained. Compared with the traditional variable-rate sprinkler, the variable-rate sprinkler with non-circle nozzle has better hydraulic performance and the spray uniformity is improved.

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.
