Investigation on optimising agricultural cultivator openers using quadratic orthogonal rotation regression

Abstract

In order to overcome the shortcomings of traditional agricultural cultivator opener, this paper combines digital drawing technology and digitisation to analyse the structure of cultivator opener, improves the structure of traditional cultivator opener, establishes a mathematical model of the transmission mechanism, and determines the relationship between various parameters. Furthermore, this paper differentiates the ideal motion trajectory, calculates the length of each rod through the iterative trajectory coordinates, optimises and improves the structure of the entire cultivator opener, and combines the simulation method to draw the structure. In order to verify the improvement effect of the cultivator opener, this paper uses the quadratic orthogonal rotation regression test to improve the structure of the cultivator opener designed and improved in this paper. From the experimental research, it can be seen that the cultivator opener designed in this paper can improve the uniformity of seeding depth, reduce soil disturbance, and enhance the compactness of the seedbed soil, which provides a reference for the design of the cultivator opener.
