THE DEVELOPMENT OF EFFECTIVE CONSTRUCTIVE AND TECHNOLOGICAL CHARACTERISTICS OF ROTARY AERATOR
Journal Title: Подільський вісник : сільське господарство, техніка, економіка - Year 2016, Vol 24, Issue 2
Abstract
The agricultural production is manufactured by modern Ukrainian agricultural enterprises in terms of different tillage quantity (starting from dozens to thousands of hectares). The agricultural machinery that is at disposal of the majority of agricultural farms is worn-out and insufficient for tilling and sowing of culture crop in optimum agrotechnical terms. The surface tilling for sowing grain crop is done with the help of both active and passive working parts. Better quality of soil preparation is provided by active working parts. But they also have disadvantages, such as not deep penetrating and leaving harvest remains, complicated construction and low technical safety, high metal capacity. All these factors reduce the effectiveness of technological process. The mathematical methods and laws of theoretical mechanics and method of formalization as well are used in the study. Results. The article offers the procedure of theoretical research of constructive and technological characteristics of rotary aerator to optimize and choose effective conditions of its work. The ways of optimizing the turn cycle of knives position of rotary ripper depending on other characteristics of this instrument and conditions of its work are analyzed in the paper. The offered procedure of aerator characteristic calculation proved the optimization of constructive and technological parameters of aerator with the help of twist pitch of knives and their number on the shaft, indicator of kinematic regimen and the speed of instrument motion. It results in increasing the agrotechnical indicators and quality of soil cultivation.
