INFLUENCE OF THE WEAR DEGREE OF CULTIVATOR SWEEP BLADES ON TRAVEL DEPTH UNIFORMITY AND THE QUALITY OF PRE-SOWING SOIL TILLAGE
Roman PINCHUK – postgraduate student of the Department of Agricultural Machines and Systems Engineering named after P. M. Vasylenko, National University of Life and Environmental Sciences of Ukraine (15 Heroiv Oborony str., Kyiv, Ukraine, 03041, e-mail: romapinchuk1997@gmail.com, https://orcid.org/0009-0009-5921-0022).
This article presents the results of comprehensive experimental studies aimed at establishing quantitative regularities in the influence of the technical condition of the cutting edge of cultivator sweeps on the agronomic quality indicators of pre-sowing soil tillage. The relevance of the work is determined by the need to ensure precise travel depth of working bodies in precision farming technologies, where seedbed stability is directly correlated with field germination and grain crop yield.
The research methodology was based on multifactor field experiments conducted on typical low-humus chernozem soils using a laser profilometer for high-precision recording of working depth. The influence of the working speed of the unit V (6, 8, and 10 km/h) and the blade blunting radius r (0.1; 0.3; and 0.5 mm) on the coefficient of variation ν and the structure of deviation distribution was investigated.
It was established that the blade condition is the dominant factor determining the stability of the technological process. Based on statistical analysis, a regression model was obtained, confirming the nonlinear nature of quality degradation as the blade becomes blunt. A synergistic interaction effect was identified: the negative influence of wear r on tillage uniformity progresses as the travel speed of the unit increases. In particular, at r = 0.5 mm and V = 10 km/h, the coefficient of variation reaches a critical value of 63.45%, which is 2.3–3.3 times higher than the values for sharp sweeps.
Analysis of the error structure showed that, when the blade becomes blunt to 0.5 mm, the share of unacceptable deviations (over 2 cm) increases from 8.5–15.5% to 35.5–39.3%. This is explained by the physical and mechanical transformation of the process: a blunt blade forms a “soil core” that generates a vertical lifting force, causing self-oscillatory processes and “emergence” of the sweep from the soil.
The scientific novelty lies in the formalization of the relationship between blade microgeometry and the statistical parameters of depth distribution. The practical significance of the work lies in substantiating the limiting “agrotechnical service life” of the sweep, which corresponds to a radius of r ≈ 0.25 mm. It has been proven that the use of self-sharpening surfacing materials (PS-12NVK-01 and T-590) extends the period of high-quality operation by 2.5 times, reduces traction resistance by 11%, and provides fuel savings of up to 7.36%, while simultaneously increasing grain crop yield by up to 30%.
