Parameters of passive working bodies of potato digging machine

The major working housing of potato digging machines is a plowshare on which energy costs and the quality of potato digging depend. The examination aims to justify the parameters of the plowshare and the divider of the combined digging working body. The constructive scheme of a potato-digging machine with a combined digging working body, the results of theoretical studies on the substantiation of the primary parameters of the main and intermediate plowshares and the divider, are presented. A special laboratory installation was used to conduct experiments. During the experiments, dividers with different capture widths were made, and the angle of the plowshare installation to the horizon was changed. The degree of damage and loss of the tuber and the traction resistance of the plowshares were taken as evaluation criteria. The outcome of the experimental investigation to determine the parameters of the plowshare is presented. Based on theoretical studies, analytical dependencies, and mathematical models were obtained that allow determining the parameters of the plowshare and the divider of the potato digging machine. It was found that for intensive destruction of the tuberous formation with minimal energy consumption and uniform transportation, the width of the colter of the combined working housing must be 45 cm, the perspective of the plowshare razor solution 90°, the perspective of inclination of the plowshare to the skyline within 27-30°, the length of the plowshare 40 cm, the width of the divider should be 45 cm, its length 39 cm, the angle the solution is 60°, the angle of installation of the working surface to the horizon in the transversely vertical plane is 65° and the range from the toe of the intermediate plowshare to the divider is 32.6 cm

Parameters of the soil-holding part of the slurry spreader

The aim of the study is the theoretical substantiation of the parameters of the soil-holding part of the slitter for manure incorporation into the soil. A slitter with soil-holding part to the tool for application of organic fertilizers was developed. The basic principles and methods of classical mechanics, mathematical analysis and statistics were used in this study. The analytical dependences for determining the parameters of the soil-holding part of the creeper were obtained. The length of the soil-holding part of the creeper depends on the speed of the machine, the angle of installation and the height of the jogger blade, the angle of the natural slope of the soil, the coefficient of friction of the soil and manure, and also their fall height. It is set that at an angle of friction of soil 23-37º, an angle of a natural slope of soil 30-41º and speed of unit movement 1,4 m/s, the length of a soil-holding part is equal 0,15-0,25 m
