UNRAVELING MECHANISM DRIVE POWER FOR EFFICIENT SEPARATION OF STEM FEED FROM MONOLITHIC RESERVES
Abstract
The rapid advancement of agricultural technology has driven a notable surge in the utilization of hydrophysical mechanisms within working bodies. An ongoing trend in hydraulic drive development is the miniaturization of its components, which consequently elevates the operational pressure of hydraulic systems to levels exceeding 500 bar. This evolving landscape necessitates research endeavors aimed at enhancing the design of hydraulic machines and allied components [1]. As agricultural production technologies evolve, novel machine categories emerge, spurring the wider adoption of hydraulic drives and the innovation of hydraulic systems boasting enhanced technical attributes [2].
In the realm of stalk feed handling from trench storage facilities, optimizing the physical and mechanical properties of feed monoliths stands as a key pathway to creating new and refining existing loading mechanisms. Within this context, the triad of material, tool (working components of the machine), and energy, as defined by Academician V. A. Zheligovsky, governs technological processes [3]. Consequently, familiarity with material properties and the confluence of structural dynamics of working bodies is indispensable for the development of machines, including stalk loaders. Furthermore, delving into the interplay between these parameters and their impact on the quality of automatically controlled drives defines the contemporary significance of this study [4].
This research is dedicated to probing the influence of the physical and mechanical attributes of stem feed, alongside the structural performance of working bodies, on the work quality and power efficiency of isolation mechanisms. The challenge of mechanizing the discharge of stalk feed from trench storage has long persisted, leading to an array of designs and continuous research into continuous and intermittent loaders. While studies have unveiled insights into the interaction between working bodies and materials, the pursuit of enhanced reliability, extended service life, and energy-efficient drives remains pivotal [5].
Various structural configurations of working bodies are deployed for unloading stalk feed from trench storage, often integrated into the front hitches of tractors (Fig. 1). Cutting-type working bodies hold prominence due to their straightforward operation and maintenance requisites. A rich body of research by scholars such as V.V. Krasnikov, V.F. Dubinin, V.G. Popov, A.A. Tolkalov, A.R. Makarov, and external contributions like those from Pirkelmann H. and Maier L. [6] have informed the development and substantiation of working body parameters for block loading of stalk forage (silage and haylage) using cutting implements. Moreover, the pioneering contributions of Academician V.P. Goryachkin underpin the scientific theory of cutting devices [7], while the standard for cutting devices is built upon the groundwork laid by L.P. Kramarenko and the experimental studies conducted by Karpenko O.M. [8]. Notably, technological frameworks for sliding cutting were pioneered by V.A. Zheligovskiy [9].
Proposing an alternative analytical approach, V.P. Goryachkin, I.F. Vasilenko, A.I. Ishlinskiy [7], N.V. Sablik, and V.N. Gyacheva introduce a methodology for determining cutting speeds of agricultural plant stalks, diverging from existing approaches [8]. Further contributions by Bosoy E.S. involve the investigation of cutting knife balance, which manifests as a wedge with varying chamfer configurations. Complementary research by N. Reznik encompasses the comprehensive theoretical and empirical underpinnings of blade-based cutting processes [3].
