Design and Applying Experiments of the Bionic Non-smooth Plow Moldboard for Paddy Field
摘要
Abstract
Soil adhesion which exists between soil and plow moldboard in the field work of paddy field plough , not only increases the working resistance and energy consumption of these machines , but also decreases the quality of work and the productivity .It was found that the non-smooth surfaces of the typical soil animal-dung beetle had the characteristics of anti-adhesion , anti-resistance and desorption by lots of tests and observations .Based on these researchers , bionic non-smooth plow moldboards were developed .In this paper , we analyzed the plowing resistance impact of dimention and distribution of bionic non-smooth structural units , then optimized parameters ( dimention and distribution ) , developed bionic non-smooth paddy field plow moldboard that had better properties of anti-adhesion and anti-resistance .The plo-wing resistances , oil consumption and plowing productivity of bionic plow and common plow were tested in paddy field . The results showed that, compared with common smooth plough, the bionic plow moldboard could reduce plowing resistance to 15.9%~18.0%, could save the fuel consumption to 11.9%, and could raise the plowing productivity to 20 .5%.Meanwhile , the bionic non-smooth plow , not only with the advantages of soil-turning , but also has highly effi-ciency of clod crushing and has a good application prospect .关键词
