Development prospects of mobile rice straw crushers

Abstract

The article presents an analysis of prospects of development of mobile crushers for utilization ofrice straw using the method of assessing engineering and technical significance of inventions. The method consists of study of retrospective patent fund for previous 10-15 years which allows to make forecast of possible ways of technology development for the next 10-15 years. Based on obtained data of a patent, there was designed the graph of change in level of prospects of combine harvesters and mobile crushers by years of research. The presented results of forecast data showed that development of mobile crushers is a promising trend.

Parameters and modes of the technological process of scattered rice sowing

“…Changing the obtained expression, we determine the radius of curvature of the inner bend of the blade, taking into account the accepted value of the central angle of the inner bend 1 = 80° [7,8,9,10].…”

Theoretical Studies of Design Parameters of Machine Elements for Surface Planting of Rice

“…To implement a given distribution of seeds by the angle of spreading, a method for designing rational places for feeding fertilizers to the centrifugal disc was developed [9,10].…”

Evaluation of Resources of a Part Depending on its Renewal Density

“…Since at the end of the machine service life, all primary parts will be replaced by secondary ones with different average resource, the resulting value should be corrected by dividing by q and k ир . Thus, the value [7,8,9] can be taken as the first approximation for the mathematical expectation of the primary resource of an element.…”
