Theoretical determination of the harvester propulsion type for rice harvesting

Abstract

Theoretical justification of the choice of harvester propulsion for rice harvesting is presented in the paper. The main features of rice harvesting were described. Moreover, soil bearing capacity is the main factor that limited the use of different harvesters in the climatic conditions of the Krasnodar krai. Thus, the numerical model was developed to determine the specific types of harvesters. The model took into account correlations of design parameters and soil rheological properties with the rut depth. The results of the calculations made it possible to justify the mass of the harvester depending on the actual bearing capacity of the soil during the harvesting period for the conditions of the Krasnodar krai.

Application of mathematical statistics to evaluate the efficiency of using modern machines

“…In scientific publications on the issue related to the evaluation of the efficiency of the use of modern machines, most often the evaluation of the efficiency of the use of modern technology is carried out on the condition that a separate part of the machine in question was turned off after its wear to the limit state, and on this basis its service life was determined. In this article, the inverse problem is solveda part of a modern machine is turned off after a known overhaul service life and then its wear is determined [1,2,3].…”

Parameters and modes of the technological process of scattered rice sowing

“…A significant disadvantage in rice production is rice sowing. This is due to the fact that the process of rice sowing has specific features and differs significantly from the sowing of grain crops [1,2]. There are two technologies of rice growing in Krasnodar Territory: technology with the "dry" processing of checks and the technology of making checks filled with water ("water").…”

Evaluation of Resources of a Part Depending on its Renewal Density

“…The method involves the organization of continuous observations of the operation of machines, registration of the operating time of the machine at the time of the occurrence of a failure and, as a result of such observations, obtaining the static series of the element time to failure. The processing of such static series by standard or original methods allows determining numerical characteristics and parameters of the element resource distribution law [4,5].…”
