Abstract:Since the beginning of the new century, the research on the field observation and test equipment has been developed, and many important results have been achieved. To overcome the shortcomings and deficiencies of the current test equipment, improve the level of soil erosion theory, scientifically prevent and control soil erosion, developing more advanced and practical soil erosion test equipment has a great significance. For the problems of measuring accuracy of automatic sand sampler and sand collection efficiency affected by strong wind interference, a shunt hedging and multi stage expansion combined reducing velocity method was proposed, a shunt hedging and multi stage expansion combined automatic sand sampler was designed, design principle of sand separator and data wireless acquisition system were expounded, and a test and analysis on reducing velocity and separation performance of sand separator, anti strong wind interference performance and collection efficiency of sand sampler were carried out. The results showed that shunt hedging and multi stage expansion combined automatic sand sampler had anti strong wind interference performance and it could collect data in real time, continuously and in a long distance wireless. The starting wind speed of free rotation was 4.23m/s, equal dynamic property was 92.94%, average sand collection efficiency was 90.42%, when wind speed was less than 18m/s, as long as soil samples which particle was greater than 55.36μm entered sand sampler, can be fully collected, power supply battery life of data wireless acquisition system was up to 31h. The signal transmission distance was 208.51m without obstacles, which can well meet the automatic observation need for soil erosion mass.

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.
