CHAIN-PADDLE DRIVING MECHANISM AND ITS PULL PREDICTION

In this paper a new driving mechanism for paddy fields, the chain-padd le driving mechanism, is described, and its working principle is expla ined. Calculations of the pull on each paddle and the total pull on th e mechanism are given according to the theological behaviour of paddy soils. Experiments for a single driving paddle are carried out in a so il bin. The experimental results show that the measured data fit the t heoretical ones well.
