Energy indicators of working bodies for tillage of steam fields in summer

Currently, one of the most important stages in obtaining high yields of the main crops is tillage of steam fields in summer. The article considers various variants of working bodies for tillage of steam fields to establish the energy indicators of the technological process. Experimental studies have been carried out to determine the energy indicators of the technological process of shallow tillage, with all variants of working bodies. During the research, such indicators were established as the traction resistance created by the working bodies, the specific traction resistance of the unit equipped with various variants of working bodies, as well as the specific fuel consumption during the main work. As a result of the research, it was found that working bodies in the form of a flat one-sided paw and flexible working bodies have significantly lower indicators of specific traction resistance. For an aggregate equipped with flat one-sided legs at a speed of 2.7 m/s, the specific traction resistance is 1950-2150 N/m, and for an aggregate equipped with flexible working bodies at a speed of 2.78 m/s, the specific traction resistance is 850-975 N/m. It was also found that the working bodies in the form of a flat one-sided paw contribute to the preservation and retention of moisture inside the soil layer and are less energy-intensive in terms of specific fuel consumption. In addition to tillage of steam fields in the summer, working bodies in the form of a flat one-sided paw can be used for pre-sowing soil preparation to the depth of seeding of grain, small-seeded and vegetable crops.
