Justification of Some Parameters for Metal Rod Feeding Screw Conveyor with Round Cross-Section in Potato Planter

Abstract

In many cases feeding screw conveyors are missing in the fertilizer tanks of some double-row potato planters, as a result of which the lower layers of fertilizers left in the tanks, are fed manually.
In order to exclude the manual work and to mechanize the process, as well as to eliminate compaction of loose fertilizer, we propose to install feeding screws with right and left turns. The design of the feeder should prevent the fertilizer compaction in the tank and ensure its constant mixing state or the so called “boiling” state. The working principles of the recommended metal rod feeding screw conveyor with round cross-section and the applied bladed screw conveyor are technologically different.
