Ripper for processing slope fields

Abstract

The purpose of the study is to substantiate the parameters of a spherical disk working body. New technology of tillage of slope fields that prevent water erosion, a design scheme of a ripper for its implementation is presented. The ripper consists of lower and upper working bodies of the “paraglider” type and a spherical disk. The study applied the laws and rules of theoretical mechanics, agricultural mechanics, mathematical statistics, and methods of strain measurement and the methods given in the existing regulatory documents (TSt 63.04.2001, TSt 63.03.2001). The new technology of tillage of slope fields makes it possible to form step ridges on the surface of the arable land and on the bottom of the furrow, which protects the soil of the slopes from water erosion. It is established that when the diameter of the spherical disk of 510 mm, the curvature radius of 56 mm, tilt angle relative to the direction of motion of 28-30° to the vertical at an angle of 17-18°, the transverse and longitudinal distance between the disc and work on the bottom ripper respectively 30 and 20 cm ensures the formation of ridges on the surface of the field according to agrotechnical requirements at a minimum cost of energy.
