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.
To address the inefficiencies of two-stage sweet potato harvesting in southern China, an integrated machine for synchronous haulm shredding and tuber excavation was developed. The equipment features a front-mounted, reverse-rotating crushing knife roller and a rear-mounted, adjustable grate-type digging shovel. The per...

Existing studies on selective pepper harvesting commonly use the pedicel as the picking target. However, for Hang pepper, dense branches and leaves cause severe fruit stem occlusion, resulting in a low harvesting success rate. To address this limitation, an end-effector that uses the fruit body as the picking target wa...
Small-scale Javanese goat farmers currently perform the chopping process manually using a sickle, a method that is time-consuming, labor-intensive, and results in non-uniform chop sizes (Syabani, 2025). This study aims to design a simple grass-chopping machine as an appropriate technology solution, determining machine...

Household composting benefits from controlled size reduction, but many reported organic-waste shredders require power levels or three-phase supplies that are unsuitable for domestic use. This study designed and experimentally evaluated a 250 W, single-phase organic-waste shredder equipped with a conveyor-assisted feedi...
