This paper presents the kinematic analysis of a paddy field weeder designed for inter- and intra-row weeding operations. There are numerous types of paddy field weeders in use all over the world, for both wet and dry land. However, most of them are designed for use in inter-row weeding. Weeds in an intra-row zone can significantly reduce yield. Hence, their removal is necessary to achieve a good yield. This study aims to analyze the kinematics of a newly designed paddy field weeder mechanism for both inter- and intra-row weeding. Various components and linkages necessary for the desired motion of the weeder have been designed using SolidWorks software. The components were assembled, and motion simulations were conducted. The kinematic analysis is based on the slider-crank mechanism. This mechanism is later used for intra-row weeding. The rotor blade for inter-row weeding was made to rotate at 200 rpm. The analysis reveals that the intra-row weeding unit traverses between the paddy plants following a sinusoidal path without disturbing them. This could eliminate weeds in the intra-row zone and possibly increase the crop yield.
