Modeling the process of liquid-mechanical cleaning of the bottom dish of the bottom conveyor of a beet harvester

Increasing the machinery productivity is a significant factor affecting the production cost. The study of technological processes of the equipment functioning and the identification of opportunities for the growth of their use indicators is an important task. For example, when analyzing the work of beet harvesting machinery, a significant amount of time was found to be wasted for cleaning the bottom dish of the bottom conveyor from soil contamination. In this case, the total drop in the daily productivity of harvesting with a beet harvester can reach 20 percent. To solve the problem of increasing the productivity of beet harvesting machinery, it is proposed to use the technology of wetting the surface of the conveyor bottom with some liquid (water). In this case, it is of interest to study the processes of interaction of soil masses with the bottom surface and their removal using mechanical action from the conveyor scrapers. This paper presents a mathematical model of the process of liquid-mechanical cleaning of the conveyor, built on the basis of classical mechanics. It allows carrying out the calculations to determine the rational modes of liquid consumption, cleaning time, and economic efficiency of the proposed solutions. The proposed results can be used to substantiate the mechanism of such processes in agricultural and other machinery.
