FIELD STUDIES OF TILLAGE VIBRATING ROLLER

A completely new design of a vibrating soil tillage roller was developed, as a result of which the quality of soil compaction was increased, while energy costs are reduced due to a decrease of metal consumption by at least 3 times in comparison with commercially available rollers. The vibrations created by the offered roller make it possible to destroy large soil fractions more effectively and ensure high-quality soil compaction. To determine suitable parameters of the soil-tilling roller, a set of studies was carried out in field conditions, by means of which suitable parameters of the proposed design of the vibrating roller were identified. Ballast weight and diameters of the pulleys on the shaft of the hollow cylinder were changed during the experiment, and the influence of these parameters on improvement criterion was also evaluated. Measurements of soil moisture, its density and structure were carried out in the course of the experiment. The experimental results were processed with modern software: Microsoft Excel, Statistica, etc. As a result of the experiment, it was revealed that the quality of soil compaction by the proposed vibrating roller is 24.7% better than that of KKZ-6 roller, which is widely used in agriculture. In this case, the improvement criterion kpl on the non-rolled section was 0.5, which is 82% lower than that of the proposed roller. The structure of the soil on the area rolled by the proposed roller fully meets the agrotechnical requirements. The proposed tillage roller of vibrating action is universal and can be used on different types of soils, provided that the ballast weight and the ratio of the pulley diameters on the axis of the hollow cylinder and on the smooth cylinder are regulated.
