The Results of Theoretical Studies of the Chisel Cultivator Rack Frontal Surface Shape

Abstract

The article deals with the theoretical study of the shape of the cross-section of the rack on the chisel cultivator. To avoid clogging the racks with plant residues, it is necessary to change its configuration so that it is possible to self-clean the racks from plant residues during operation. To find the optimal shape of the cross-section, the asymmetric experimental shapes of the frontal surface of the racks are studied. The conducted research shows that the condition of sliding plant residues towards the flat face of the frontal surface of the rack depends on the angle of its inclination to the direction of movement, the physical and mechanical properties of the soil and plant residues, as well as the thickness of the rack.
