Research results for eccentric tillage rollers

Abstract

An innovative double-drum eccentric roller has been developed. The proposed roller allows you to effectively destroy soil lumps and evenly compact the soil surface. Its main advantage is the varying effect on the same areas of soil with its working surfaces, due to which the maximum result of crushing of soil lumps is achieved. The roller is tested in the field with the quality control of its tillage in accordance with agro-technical requirements. As an optimization criterion, we adopted the coefficient of conformity to the standard ks. It characterizes the quality of soil cultivation by the proposed roller from the position of conformity of the structural composition of the soil to agrotechnical requirements. A comparison of the processing quality of the proposed roller and ring-spur roller was made. When the structural composition of the soil fully complies with the agrotechnical requirements ks = 1. Experimental studies of the eccentric roller made it possible to determine its optimal parameters for which the coefficient of compliance with the standard ks = 0.72, which is 20 % better than the ring-spur roller KKSh-6G-02 (ks = 0.52). The achieved quality of soil cultivation by the eccentric roller made it possible to increase the yield of spring wheat by 320 kg/ha in comparison with a ring-spur roller, which provides a profit of 3593 rubles per 1 ha.
