System of energy criteria in the justification of technical units for field production

Abstract

The article shows the importance and necessity of energy analysis of both machine technology, as a whole, and machinetechnological aggregates in order to compare several variants of technical solutions of the designed equipment (power units, machines, aggregates) for field cultivation. The necessity of introducing additional energy criteria when designing machine technologies and creating technical means for their implementation is justified.

The Design of a Dump Plow for Processing Heavy Soils

“…Depending on the direction of movement and the location of the blade, relative to the horizontal and vertical planes, the nature of the impact of the two-sided wedge on the soil varies. A dihedral wedge with a y angle (Figure 2, b) separates the formation from the furrow wall, pulls it aside and compresses it in a horizontal plane [9][10][11][12][13][14][15][16][17].…”

“…Figure 1. Deformation of the soil by flat (a -f) and curved (e) wedgesA dihedral wedge with an angle a (Figure2, a) separates the formation from the bottom of the reservoir, lifts it, compresses it in a vertical plane and splits it into separate lumps.A dihedral wedge with a y angle (Figure2, b) separates the formation from the furrow wall, pulls it aside and compresses it in a horizontal plane[9][10][11][12][13][14][15][16][17].The combined action of wedges with angles a and y contributes to the destruction of the formation in two directions. Further crumbling of the chipped pieces stops when they move along the surface of the wedges, since the angles α and γ have a constant value.…”

Systematization of Steam Cultivators and Structures Working Bodies

“…Designs are being developed to ensure the stability of the steam cultivator without support wheels [6]. At the same time, mounted steam cultivators have less longitudinal stability during transportation [9].…”

Kinematic Analysis of a Disk Working Body with a Changing Radius of Curvature

“…With the improvement of crop cultivation technologies, disk working bodies are increasingly being used as the basic working body of a tillage unit [1][2][3][4]. This is due to both economic and technological aspects [5][6][7][8][9][10][11]. In parallel with the increase in the intensity of the use of disk working bodies, their improvement also occurs [12][13][14].…”
