Abstract

Summary The purpose of research. Evaluation of the quantitative and qualitative parameters of the wear of the disc working bodies of the DL-2.5 soil tillage unit on the basis of monitoring their condition during tests in the conditions of experimental operation over a 6-year period and forecasting the possibility of further operation of the unit. Research methods. Analysis of the machine design, determination of the linear dimensions of discs by standardized measurement methods and statistical data processing. Research results. The intensity of the wear of the disk working bodies depending on the earnings, the forecast of the resource before the loss of quality is established. Conclusions. On the basis of experimental studies, objective and reliable information was obtained about the parameters of the wear of the disc working bodies of the DL-2.5 soil-cultivation unit in the conditions of economic operation in the forest-steppe zone of Ukraine. During the six-year period of testing, with a total volume of work performed by the unit of 2430.6 ha (2017 – 395,4 ha; 2018 – 413,3 ha; 2019 – 456,3 ha; 2020 – 357,6 ha; 2021 – 400,0 ha; 2022 – 408,0 ha) and the achievement of cultivation per disc - 120 ha, the wear of the working edge of the discs of the front and rear rows amounted to 21,1 mm and 11,5 mm, respectively, for the permissible value of 35 mm, or in percentages, respectively - 60,2 and 32,8. Accordingly, the estimated residual resource is forecast at the level of 39,8 % and 67,2 %. According to the results of resource tests during 2017-2022, the unit maintained its operable condition, provided the necessary regulation, aggregation, transportation and had an aesthetic appearance. The obtained results can be used by machine builders as an informative base for fine-tuning disks and forming standards for their performance, and by manufacturers of g. products, as information on the choice of reliable equipment and the potential of its service life. Prospects of research in this direction consist in the possible multiplicity of accounting for the general conditions of operation of disk tools, the variability of structural and technological schemes, and can also be used as methodical material for p. g. machines that have discs in their composition.

土处理机组dl-2.5试验运行过程中盘磨损的研究
研究目的。通过对DL-2.5型土壤耕作机组盘式工作机构在6年试验运行条件下的工况监测,对盘式工作机构磨损的定量和定性参数进行评价,并对机组进一步运行的可能性进行预测。研究方法。分析了机床的设计,通过标准化的测量方法和统计数据处理确定了圆盘的线性尺寸。研究的结果。盘式工作机构磨损的强度取决于收益,建立了对资源损失前质量的预测。结论。在试验研究的基础上,获得了在乌克兰森林草原地区经济运行条件下DL-2.5型土壤耕作机组盘形工作体磨损参数的客观可靠信息。在为期六年的测试期间,该单位完成的总工作量为2430.6公顷(2017年- 395,4公顷;2018 - 413,3公顷;2019 - 456,3公顷;2020 - 357,6公顷;2021年- 400,0公顷;2022 - 408,0公顷)和实现每盘种植- 120公顷,前排和后排盘的工作边缘磨损分别为21.1毫米和11.5毫米,允许值为35毫米,或百分比分别为- 60,2和32,8。据此,估计剩余资源量分别为39.8%和67.2%。根据2017-2022年期间的资源测试结果,该装置保持了其可操作状态,提供了必要的调节、聚合、运输,并具有美观的外观。获得的结果可以被机器制造商用作微调磁盘和形成其性能标准的信息基础,也可以被产品制造商用作选择可靠设备及其使用寿命潜力的信息。在这个方向上的研究前景包括对圆盘工具的一般操作条件的可能的多重计算,结构和技术方案的可变性,也可以用作在其组成中有圆盘的p.g.机器的系统材料。关键词:土壤耕作单元;试验;磁盘工作体;无聊的钢铁;磨损;预计资源。
