2026-09-18 A tray-type paddy field chinese mitten crab feeding platform doi:10.57760/sciencedb.iga.01153 en The present utility model provides a tray-type paddy field Chinese mitten crab feeding platform, which relates to the technical field of aquaculture feeding. It includes a fixed frame body, with rotating shafts pivotally connected between the inner walls on both sides of the fixed frame body near the front and rear edges. A screening film is arranged between the outer surfaces of the two rotating shafts. The screening film is arranged in an overlapping manner up and down between the two rotating shafts, with the upper and lower screening films closely adhering to each other. Screening holes are opened on the top of the screening film and penetrate through to the bottom. The screening holes on the two overlapping screening films distributed vertically between the two rotating shafts are staggered relative to each other. The utility model addresses current issues in rice-crab integrated farming, where Chinese mitten crab cultivation occupies a considerable proportion. However, feeding Chinese mitten crabs in paddy fields faces problems such as high cost, low efficiency, and water pollution due to the lack of a dedicated feeding platform. tray-type; chinese mitten crab; feeding platform 刘宏远 PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
