Abstract
To promote the mechanization of the tobacco industry, a self-propelled tobacco stem harvester was designed in this study. To improve harvesting efficiency under varying terrain and planting conditions, the machine integrates key functional components, including a chain-clamp conveyor and a loosening shovel with optimized structural parameters. The performance of these core components was analysed using 3D modelling and finite element simulations conducted in ANSYS. Field experiment optimization indicated that the optimal operating parameters were a clamping chain speed of 0.7 m/s, a forward travel speed of 0.4 m/s, and a clamping chain gap of 12 mm. Experimental results showed that the harvester achieved a leakage rate of 3% and a breakage rate of 7%. Overall, the machine demonstrated reliable performance and satisfied practical operational requirements. This study provides an effective technical solution for the mechanization of tobacco stem harvesting, contributing to reduced production costs and the advancement of agricultural modernization.
