В статті розглянуто типи висівних апаратів зернових сівалок. Проаналізовано їх переваги та вади. Запропоновано конструкцію вібраційного висівного апарату та методику первинних розрахунків його основних параметрів – частоти та напряму коливань. Побудовано графік визначення режиму роботи апарату в залежності від цих параметрів. Using of vibrations for the ordinary sowing of seed to this time not used in practice, although simplicity of construction as compared to the pneumatic sowing is obvious. In the article the new construction of oscillation seedmeter is offered and the theoretical calculations of basic his office hours are conducted. Worked out differential equations, describing motion of seed in the process of oscillation motion. On the basis of agrotechnical requirements the parameters of work are expected, namely, frequencies and directions of vibrations, providing the set process of portage of seed. The analysis of different terms of work of vehicle is conducted. As a result was certainly following. On the basis of the conducted theoretical researches certainly parameters and modes of operations of the offered vehicle. The chart of dependence of the mode of operations of sowing oscillation vehicle from correlation of frequency of vibrations of tray and corner of vibration and given recommendations is made in relation to subsequent researches. |
