Improvement of working bodies for cutting and rising the soil of a rope-separation machine

Abstract

The subject of the study is the process of functioning of the working organs of a tillage ripper-separating machine that changes the structure and density of the treated soil layer in accordance with the requirements of agronomical science. The object of the research are the disk elements of the lifting and trimming device, which make it possible to significantly improve the efficiency of the technological process of soil movement by means of a share, while reducing the specific energy intensity of the process. In carrying out the work, theoretical studies using mechanical and mathematical modeling of the interaction of working organs with soil were used. The initial information for the study justification was obtained by analyzing the literature sources. The urgency lies in the fact that the simultaneous use of parallel located freely rotating flat discs together with the plow will improve the methods of presowing tillage to improve its agrotechnical qualities. A mathematical model is proposed for the interaction of flat, free-rotating disk working organs with soil, which separates the soil layer from the soil by a detachment. This model makes it possible to determine the components of the resulting soil reaction on the sections of the tillage ripping-separating machines equipped with similar working bodies. The analysis of the effect of individual geometric parameters on the magnitude of the friction forces of the surface area of the rotary tillage body is carried out. The target group of consumers of information in the article are designers, specialists engaged in the development of soil-cultivating working bodies.
