Russian and Indian scientists have completed a joint project to create tillage machines for small farms and foothill areas. The development, carried out at RSAU-MTAA named after K.A. Timiryazev in partnership with the North-Eastern Institute of Science and Technology of India, proposes to abandon the classic plow in favor of screw working bodies with active drive and vertical arrangement.
The problem of foothill soils is stones, rocky rocks, clayey structure and small field contours. Traditional equipment here is either ineffective or simply does not pass. In response to these challenges, researchers proposed a new concept: screw working bodies. Scientists created a mathematical model of their work, determined the optimal modes, and designed the structure using topological optimization.
As a result, three versions of machines appeared: a manual universal machine (with movement due to muscular strength), a self-propelled universal machine and mounted equipment for a small traction class tractor. In India, equipment was manufactured for the production of screw bodies, and three prototypes and a stand for wear tests were also created.
A feature of the project is preparation for real production. A scheme of a dealer network for India has been developed: the sale of machine kits according to the DIY ("do it yourself") principle, assembly by local workshops and service by regional representatives. Now the proposed solutions are being tested.
