摘要

目前,将土壤按处理层深度破碎分离相结合的松脱分离机已经走到了前沿。这些机器的转子叶片与土壤的相互作用包括三个阶段:土芯的形成;稳定的运动;从分离网格中倾倒土壤。本文确定了土的位移方向、位移幅度、开膛机通道后形成的沟槽的参数和形状。在理论研究的基础上,建立了工体与土体相互作用的数学模型。实验得到了初步数据,并对模型进行了验证。结果表明,供给土层厚度和撕裂器断裂角度对转子撕裂器的输送能力影响最大。将转子叶片入土角从45°减小到30°,使松分机的二次进土量提高了40倍以上。转子撕裂器的宽度实际上不影响输送能力。在不改变转子设计的情况下,改变撕裂器进入土壤的角度可以获得所需的撕裂和分离机的输送能力。本研究的现实意义在于在不增加劳动生产率能量指标的情况下提高劳动生产率的可能性。

Transporting Ability Calculation of the Rotor of Soil-Cultivating Loosening and Separating Vehicle
Abstract Currently, loosening and separating machines that combine the operations of crumbling and separating of soil according to the treated layer depth have come to the forefront. Interaction of the rotor blade of these machines with the soil comprises three stages: soil core formation; steady movement; and dumping of soil from the separating grid. The article determined the direction and magnitude of soil displacement, parameters and shape of the furrow formed after the ripper passage. Based on theoretical research, a mathematical model of the interaction of working bodies with the soil was developed. The initial data were obtained experimentally, and the model was justified. As a result, it was found that the supplied soil layer thickness and the fracture angle of ripper have the greatest influence on the transporting capacity of rotor ripper. Reducing the rotor blade entry angle into the soil from 45° to 30° made it possible to raise the second soil feed of the loosening and separating machine by more than 40 times. The width of rotor ripper practically does not affect the transporting capacity. Changing the angle of ripper entry into the soil allowed obtaining of the required transporting capacity of ripping and separating machine without changing the rotor design. Practical significance of the study lies in the possibility of increasing the work productivity without increasing its energy indicators.
