RESEARCH AND DEVELOPMENT OF A NEW IMPLEMENT WITH MODERNIZED SPIKE TILLAGE TOOL FOR EARLY SPRING SOIL THREATMENT

Abstract

The article is devoted to the issues of improving the tillage tool of a tooth implement in order to increase the efficiency of early spring soil treatment. The tillage tool chosen for the study is a standard tooth of a serial soil tillage implement, the BZTS tooth harrow. In the work, the authors propose upgrading the tooth harrow by tilting the teeth from the vertical against the direction of movement, which will not only increase productivity, but also make the soil tillage process more qualitative and environmentally sustainable. Studies have shown that soil mass is accumulated and soil body is formed on the working surface of a standard tooth tillage tool. Under the same conditions, soil formation on the surface of the modernized tillage tool was formed in a small volume, and in some teeth, it was not even formed. This indicates that soil sliding along its working surface is ensured depending on the variable value of the coefficients of internal and external friction of the soil. Based on the results of the research, a new implement with modernized tooth tillage tool was developed, the production test of which was carried out in the field conditions during early spring soil treatment. The results and conclusions of the article are of interest to agricultural enterprises and scientific researchers working in the field of agriculture and mechanical engineering.
