Combined machine for preparing the soil for re-sowing crops
Аннотация
The technologies used to prepare the soil from under winter crops for re-sowing consist of numerous soil preparation operations, which lead to loss of moisture, delay in the preparation of the soil for sowing and increase operating costs. The purpose of the research is to develop a combined machine for preparing the soil from under winter crops for sowing repeated crops. The authors developed a combined machine consisting of non-shaft housings, spherical disk batteries and a roller. The basic principles and methods of classical mechanics, mathematical analysis and statistics were used in this study. It is established that the most optimal design scheme of a combined machine is considered to be a scheme consisting of non-shaft housings with crushers, a battery with cut-out spherical disks and a roller. The experimental studies have established that the shaft-free body of the machine with dyes provides high-quality crumbling of the soil with minimal energy consumption. The main parameters of the machine and its technical characteristics are given. It is established that the proposed machine reliably performs the specified technological process and its performance indicators fully meet the requirements. The use of the developed combined machine for non-tillage of the soil and its preparation for sowing of repeated crops makes it possible to reduce operating costs in comparison with the existing technical means for processing each hectare of the field by 53.4 %.
