Kinematics Features of Hammer Perforated Tillage Roll

Abstract

The task of improving the quality of agricultural tools by improving the technological processes of their functioning, taking into account the kinematic features of the combined impact of working elements of tools on the soil environment is important from a scientific and technical point of view. To form the required structure and density of the soil layer at the depth of sowing, a hammer perforated tillage roller (HPTR) has been developed. The study aim is to improve the quality of post-sowing compaction and structuring of the soil layer in the seed location zone based on the development of an innovative design of HPTR that combines different effects on the treated environment. The object of research is the kinematic mode of operation of the HPTR, equipped with cylindrical hammers installed at the ends of the rod, which, in turn, are radially and pivotally installed on the axis of the gunFeature of offered HPTR is the excitation of hammer vibrations, which changes the kinematic parameters of the tillage tool as a whole. Lagrange equations of the second kind are used to describe the process of HPTR operation, which is represented as a system of material objects with several degrees of freedom. The conducted studies revealed the periodic nature of changes in the strength of the impact of HPTR on the soil. The obtained equations allow us to determine the features of the HPTR movement at different masses of a hollow perforated cylinder and cylindrical hammers. This is of great importance for increasing the efficiency of soil bolster destruction and creating the soil structure recommended for winter crops sown in the Middle Volga region.

Analysis of the structural composition of the soil during field studies of a soil-cultivating vibratory roller

“…Surface tillage includes such operations as cultivation, peeling, harrowing, rolling, etc. [1][2][3] Now there are a fairly large number of types and means of mechanization of tillage, but let's focus on rolling, since soil rolling ensures the fulfillment of agrotechnical requirements for the most important indicators, namely, soil density and structure [5][6][7][8].…”

Studies of the vibratory roller from the standpoint of compliance with the agrotechnical requirements of soil density and structure

“…The main task of surface treatment is the formation of a soil layer with optimal parameters in terms of density, structure, bedding, etc., which fully meet the agrotechnical requirements [1][2][3].…”
