Abstract

Summary. This article is dedicated to the subject of designing additional tools for use with reversible ploughs that cuts and loosens topsoil. The aim is to reduce power consumption spent for soil tillage by using reversible ploughs with roller cultivators. Methods. Theoretical and experimental studies of the topsoil movement on the plough’s wing, the mouldboard and beyond. Results. Analysis of the movement of soil particles falling from the top edge of the plough’s moulboard has allowed to obtain analytical dependence for determining the size range of soil particles based on the geometry of the working surface of the plough’s body (distance from the soil surface to the top edge of the mouldboard, the angles of the edge of the mouldboard) and the kinematic parameters of the soil (speed of the plough and roller cultivator, soil particles speed on the edge of mouldboard, soil particles descent time). A research, on the movement of the soil particles, on the mouldboard surface of the plough's body is presented. The section through the mouldboard perpendicular to the wing of the plough is described by the equation of the "inverted" cycloid and based on it the dependences have been obtained to determine the kinematic parameters of the movement of the soil particles on the surface of the plough’s body, depending on the mouldboard type and properties of the soil. Results obtained in this article allow to design the roller cultivators for reversible ploughs with determined parameters of installation, in which the power consumption costs of the plowing process will be minimal. Conclusions. Obtained analytical dependences, that determine kinematic and technological parameters of the soil movement on the working surface of the plow, the section through the orthogonal wing that has the form of an "inverted"cycloid, the variable design and technological parameters of the plough and the conditions of its operation, allowing to justify the installation parameters of the roller cultivator relative to the plough, taking into account the proposed correction ratio, which depends on the mechanical properties of the soil and its structure.

土壤耕作用犁耕装置附加附件安装参数的测定
总结。这篇文章是专门设计额外的工具,使用可逆犁切割和松动表土的主题。目的是通过使用可逆犁和滚筒耕耘机来减少土壤耕作的电力消耗。方法。耕犁翼、模板及其外表层土运动的理论与实验研究。结果。分析土壤颗粒的运动从顶部边缘的犁moulboard允许获得分析依赖土壤颗粒大小范围的确定基于犁的工作表面的几何形状的身体(土壤表面的距离的上边缘模板,模板的边缘的角度)和土壤的运动参数(犁和辊式中耕机的速度,土壤颗粒速度在模板的边缘,土壤颗粒下降时间)。对土壤颗粒在犁体模板表面的运动进行了研究。垂直于犁翼的通过模板的截面用“倒”摆线方程来描述,并在此基础上,根据模板类型和土壤性质,获得了确定犁体表面土壤颗粒运动的运动学参数的依赖关系。本文获得的结果允许在确定安装参数的情况下设计可逆犁的滚筒耕耘机,其中耕作过程的电力消耗成本将最小。结论。获得了土壤在犁工作面上运动的运动学和技术参数的解析依赖关系,通过具有“倒”摆线形式的正交翼的截面,犁的可变设计和技术参数及其运行条件,允许合理的安装参数相对于犁,考虑到提出的校正比,这取决于土壤的力学特性及其结构。
