Cultivator points of the rotary tillage loosening and separating machine of the stratifier

Abstract The object of the study is the process of functioning of the working bodies of a rotary tillage machine, with the help of which the lifting and feeding of the soil cut by them to the loosening and separating device is carried out. The technological process of the machine operation is described with the cultivator points from the chisel working body installed in the front part of the pointed paw, which are located at an angle of 260 to the horizon and properly ensure the penetration of the working bodies into the soil. Using the method of variational calcification, the form of the minimum traction resistance cultivator points for lifting and feeding the soil to the loosening and separating device is justified. It was experimentally determined that a cultivator points with a theoretically justified profile has a traction resistance 38.7% less than a cultivator points with a straight profile. The relevance of the study is to ensure the minimum traction resistance of the working bodies for cutting and lifting the soil of a rotary tillage machine, which will make it possible to reduce energy costs for pre-sowing tillage. The target group of consumers of information in the article is designers, specialists engaged in the development of tillage machines.
