Pressure conditions inside the workspace of mulcher with vertical axis of rotation

Popis výsledku v původním jazyce

Maintenance and treatment of permanent grassland areas, areas left fallow and mulching in combination with other workflows (mowing, grazing) represent advantageous procedures. Conventional impact grass cutting and chopping is energy demanding. The energy demands and the quality of work is affected by air flow and pressure conditions inside the mulcher workspace. In this paper the pressure inside the workspace of the mulcher with vertical axis of rotation is measured and analyzed. The dependencies of pressure inside the workspace of mulcher on rotation speed and distance from the axis of rotation were examined. The torque and power input of the mulcher are also presented. It was found that inside the workspace the negative pressure is created due to centrifugal force and the pressure decreases with the square of rotation speed.
