From the basic principles of the design collection instrument sand paper introduces a new collection of farm -land erosion and sediment structure and working principle instrument using Fluent software instrument collection sand sand separator was simulated.From the simulation results, the exhaust port and the discharge sand breath flow fell about 90%.After 0 FDY-1.2 Mobile erosion wind tunnel test verification, the results show a significant deceleration perform-ance of new farmland erosion and sediment analyzer set to improve the collection efficiency has played a key role in the sand,sand average collection efficiency of 92.29%,and other power of up to 95.8 %, we can better meet the require-ments of wind tunnel tests and wind observation.
