Procedure and results of experimental research of the eccentric roller
... Before the beginning of the field experiments, the moisture content in the soil was measured using a TDR 100 moisture meter in the seed location area (from 3 cm to 6 cm) in five repetitions, along the diagonal of the selected area for the experiment, while the distance between measurements was chosen the same, as a result soil moisture content varied from 24% to 28%, which exceeds the allowable soil moisture content for tillage and sowing, but the main goal of the experiment was to determine the optimal parameters in the field during the sowing campaign [9][10]. ...
The article presents the results of experimental studies of a soil-cultivating vibratory roller, as a result of which adequate mathematical models were obtained from the standpoint of compliance with the reference values of the structural composition of the soil. According to the results of the research, it was revealed that the quality of rolling by the developed vibratory roller is 23.9% better than that of the serially produced roller KKZ-6. The optimal speed of movement of the unit and the frequency of rotation of unbalancers are also determined.
A completely new design of the wave roller is presented, which has no analogues produced by the industry. As a result of research on barley crops, it was revealed that the optimization criterion kse after treatment with the developed wave roller is 0.81. The density and aggregate composition of the soil in all parts of the field (in the ridges and in the troughs of the wave relief) fully meets the agrotechnical requirements. In the area after treatment with a serial roller KKZ-6, the optimization criterion kse = 0.67, which is significantly lower than that of the proposed wave roller. At the same time, soil clods were found on the soil surface, the size of which exceeds 50 mm, which does not meet the agrotechnical requirements for rolling. Studies conducted under production conditions made it possible to determine that the rolling of barley crops with the proposed wave roller increased its yield to 47.2 centners per hectare (by 12.4%) compared to 42 centners per hectare after rolling the crops with ring-toothed rollers KKZ-6.
