Design of a mechanism for a new cultivator (Part 1: Path generation and dimensional synthesis)‎

Authors

Abstract

Mechanical weeding is one of the non-chemical methods to control weeds. In this paper a ‎new mechanism has been presented for mechanical cultivation. The machine works based on ‎the manual tools operation, which farmers still use in small scale for weeding and consists of a ‎number of four-bar linkage mechanisms. Each mechanism consists of a blade which moves ‎forward (active course) and backward (passive course). The three precise position methods ‎were applied to design the mechanism. The Matlab software was used for solving the equations ‎and drawing the path of motion. Considering the parameters and solving the equations, a four-‎bar linkage (crank-rocker) was proposed.‎
