A two-way plough with the bionic non-smoothtechnology in paddy field

摘要

Based on the bionics principle, the surfaces of mould board of two-way plough aredesigned into non-smooth surfaces with bionic non-smooth structure. The draft resistances of bionicplough and common plough were tested using a virtual instrument in paddy field. The data wereanalyzed and compared between bionic plough and common plough by statistical software.. A ploughwith kidney -shaped convex surface has been proposed in this work. Under the identical condition, thedraft force of the designed plough with kidney -shaped convex surface was 5% lower than those of thedesigned ploughs with smooth surface and other non-smooth surfaces. In addition, it was found thatcultivating wide and deep of plough with bionic non-smooth surfaces was stable. The test alsoindicated that there was a great deal of soil adhered to the surfaces of the common plough and otherploughs with non-smooth surfaces. It was found that the draft forces of the designed plough withnon-smooth surface must not decrease, the other way round increase because of being affected byconvex shape and distribution.
