ASPECTS ON THEORETICAL ANALYSIS OF WORKING PROCESS PERFORMED BY TECHNICAL EQUIPMENTS FOR CHOPPING PLANT DEBRIS IN ORDER TO CLEAR THE FIELD

The paper presents theoretical aspects on working process of rotors of technical equipments designed for chopping vegetal debris and fodders. Generally, the chopping devices with rotor, with the rotor axle in horizontal plane and normal position (perpendicular) with the machinery moving direction are used for constructing equipments for harvesting fodder crops or for those of chopping vegetal debris where they perform multiple tasks. They make the cutting, the chopping of plants and throwing the chopped material into the collecting trail or, with the case of cutting and chopping machinery, the evenly spreading of chopped material over the soil surface. The main factors that influence the chopping degree are the physical – mechanical features of the chopping material that are very different with the crop variety and the constructive and functional parameters of the chopping device
