Patent analysis of design features of non-cereal crop choppers

Abstract

The paper provides an overview of patent developments - mounted and trailed mobile choppers-straw spreaders. Their analysis is carried out and the shortcomings in the process of chopping and field distribution of the non-cereal part of rice crop are indicated. A design of PIRS-2-2 mobile trailed rice straw chopper is proposed, which is to eliminate the disadvantages inherent in the choppers designed for chopping cereal straw. The use of this machine will ensure the required quality of rice straw chopping and uniform distribution of check plots to a given width.

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].…”
