Study of the dynamics of the combined coulter
Abstract
A comparison is made of the dynamics of multiple design options combined coulter. Proposed opener enables simultaneous seeding row crops and seed tape after the subsurface application of herbicides. From the series opener, he is characterized by a rear mounted lancet extension. We consider several options lancet extension coulter, which differ by the presence and installation of coverers. Studied the dynamics of questions compared structures. The basis of practical and experimental studies on the method of partial acceleration. For representation of the experimental data used in analytical form trigonometric series. Their parameters are determined using the methods of direct Fourier transform and successive approximation. The algorithm of the recovery line travel opener using the method of successive approximations. A comparison of the Fourier method and successive approximation with respect to the problem of reconstructing the trajectory of coulter. The advantages and disadvantages of the method of successive approximation, which is recommended for use to restore order on line coordinates germinating plants. In order to compare the stability of experimental the working stroke coulters equipped lancet extensions, use the standard deviation of the horizontal angle of rotation of the opener to the vertical axis and the standard deviation of the depth control coulter of the mean. It is shown that the combined coulter embodiment of the lancet extension opener, which coverers are installed asymmetrically, has performance stability working stroke, comparable to the control, according to which the coulter is factory construction.
