THEORETICAL GROUNDING OF RATIONAL DESIGN OF WORKING ELEMENTS OF STRAW DISPERSER OF GRAIN COMBINE HARVESTER
Journal Title: ISB-INMA TEH AGRICULTURAL AND MECHANICAL ENGINEERING - Year 2017, Vol 0, Issue 1
Abstract
The article presents the theoretical description of the process of interaction of straw particle and concave surface of guide plate of deflector of grain combine harvester disperser. The equation of particle present velocity is obtained. It is proved that particle velocity decreases by 8.5% at plate radius reduction from 5 m to 4 m, and by 15%. and particle angle of attack convergence reduction from 25° to 50°. To decrease adverse effect of particle interaction with guide surface, we suggest the usage of bladed choppers with slantwise set cast blade.
