Analysis of disk working bodies of forest soil-cultivating implements

Abstract

The designs of disk working bodies are analyzed and a variant of the developed combined tillage tool is presented. One of the main active working bodies is disc working bodies, which are mounted on various forestry and agricultural machinery: plows, seeders, harrows, etc. and are intended for processing forest areas during reforestation. Disk working bodies are classified, which are divided by type, purpose and design. Due to the fact that forest soils are flooded with roots, stumps, stones, and when carrying out reforestation work they need high-quality preparation, it is required to increase the number of passes through the cultivated territory. Disc working bodies from the moment of their creation continue to undergo improvements aimed at increasing efficiency, increasing strength characteristics, etc. Disc working bodies represented a wide range of design features, but in the subsequent range was concentrated on reducing traction resistance. A change in the design in the process of studying the working body led to the creation of cutouts of various geometric sizes, one of the positive characteristics was a decrease in the traction force required for cutting, crumbling the soil, as well as an increase in quality characteristics.
