Research and Development of a Mechanism for Fixing the Hydraulic Cylinder for Controlling the External Working Element of a Garden Milling Machine and Determining its Optimal Parameters

Abstract

The article is devoted to improving the operation of the control system of the remote soil-cultivating working element of the garden milling machine (patent of the Republic of Armenia, No. 2993 A, 16.02.2016), as a result of which it becomes possible to bypass the working element of thick-trunked trees and trees deviated from the row line, as well as slippages and other obstacles, with simultaneous near-trunk processing. Based on the research of the Scientific Research Institute for Agricultural Mechanization and Automation of the Armenian National Agrarian University (ANAU), a control system for the remote working body of a tillage machine (patent of the Republic of Armenia, AM20230106Y, 01.07.2024) has been developed and implemented. To fix the hydraulic cylinder piston in intermediate positions, depending on the total value t of the tree trunk diameter, the width of the protective zone and the amount of overlap of the treatment, a mechanism for adjusting the length of the slider was investigated and developed and its optimal parameters were determined. For the purpose of practical regulation of the slider length for specific values of t, a corresponding nomogram was constructed.
