Abstract: Among the bed material measurements, the domestic already has the shovel type, bowl type, clams type, cone type, clamp type sampler and so on, most of which were created before 1980s. These entrances are often small and depend on the other external force to get closed. This results in the situation that few or no large pebble can be extracted in field work sampling. Moreover, most samplers are disturbed by the water flow, and are difficult to get those light and tiny surface bed materials sampled. These drawbacks play a great impact on the work efficiency and measurement quality. In order to improve these drawbacks, JJ-CY02 bed material sampler is created with double bucket, trigger-type automatic doors, streamlined shape and empennage. Verified by facts, JJ-CY02 bed material sampler is proved to get enough and complete grain-size distribution of clay, sand and pebble much easier, and greatly enhance the field word efficiency and hydrological measurements quality.
