Stepped plow with cutting disc for tillage of sloping fields

Abstract

The aim of the research is to justify the design scheme and mutual arrangement of plough working elements for anti-erosion treatment of sloping fields. The authors have developed a stepped plough, which carries out beardless smooth plowing of sloping fields and formation of anti-erosion intermittent. The proposed technology firstly performs the turnover of layers within its own furrow, strip-tillage loosening of soil, then anti-erosion ridges and intermittent furrows with barriers of the arable land. Plough, carrying out this technology consists of stepwise located in the longitudinal direction of the right-harrowing screw bodies, skimmers, laughers and cut spherical discs that form on the surface of the arable anti-erosion ridges and pre-irrigated furrows with obstacles. The constructive scheme of offered plough. Parameters of spherical disk, mutual positioning of body, ploughing tool and spherical disk have been justified by theoretical investigations. For providing of the required quality of work diameter of the cut spherical disk should be within 420-510 cm, the angle of its installation 28-32°, minimum angle of sector of cut should be 49°, the depth of the sector not less than 10 cm, cut spherical disk even not less than 110 cm.
