SUBSTANTIATION OF PARAMETERS OF A ROTARY IMPLEMENT FOR SURFACE TREATMENT OF SOIL WITH INCLINED HEXAGONAL DISC

For surface tillage, rotary implements with disk working bodies are widely used. In recent decades, intensive research has been carried out on the development of tools polygonal disks. They were implemented in practice form hexagonal disks mounted a shaft at an angle 90° and performing usual rotational movement around its axis. Of interest discs, which fixed obliquely shaft. The well-known tillage tool inclined square discs was not practice, since it turned to be technologically unstable did provide uniform depth tillage. developed soil-cultivating tool, these shortcomings eliminated. As result study, analytical dependences obtained, made possible substantiate parameters containing disks: width (module) capture B = 1.8 m; number batteries - 2; diameter D 0.32…0.48 fastening  > 50°…55°; distance between disc centers S 0.100…0.105 battery n 17; rotation (displacement) one relative other axis ɛ 11.25°. A formula also obtained reveal regularity change entry into soil. calculation showed that this during is variable parameter varies within 72.5° ... 107.5°. This contributes self-cleaning inter-disk space from adhering soil plant residues used determining traction resistance implement.
