A Study on Planter's Suction Seed Feed Mechanism with Combined Inhaler

This paper describes the structure and working principle of planter' s suction seed feed mechanism with combined inhaler analyses the construction and parameters of the main parts. Through regression analysis, a polar coordinate equation to form spiral groove of the combined inhaler is set up. Based on this, the paper discusses the forces acting on and the movement of the seeds in the seed feed, also analyses the main factors affecting the feeding performance.
