Effect of top cover shape on energy demands and workspace pressure of mulcher

Popis výsledku v původním jazyce

Mulchers with vertical axis of rotation are highly energy demanding machines and it is expedient to increase their effectiveness. The paper deals with evaluation of the effect of the shape of mulchers workspace cover on energy demands and pressure conditions of the workspace of mulcher with vertical axis of rotation. The pressure conditions inside the workspace are connected with the airflow which is vital for the correct function of the machine. The laboratory model of one mulchers rotor was used for the measurement. Three workspace cover shapes were used for the measurement, including shapes called drop, toroid and flat cover which was used as a reference. The measurement was carried out at cutting speeds of 21, 42, 63, 84 and 105 ms-1. The proposed shapes of mulchers workspace cover showed higher energy demands, while the cover in shape toroid significantly affected the pressure profile in the mulcher workspace. c 2017, MM publishing Ltd.
