Abstract:Experimental determination of ploughing quality and energy consumption carried out on loamy soils most common for the arable lands in European part of Russia. The field tests done for three standard types of mouldboard body surfaces: cultural, semi-helicoidal (cylindroid) and helicoidal. Results shows that bodies with cylindroid mouldboard surface had better soil crumbling against cultural (digger) body surfaces. Helicoidal bodies supplied better quality of soil layer turnover than cultural and semi-helicoidal… Show more

“…One of the performance indicators here is the quality loosening of each of the horizons [1,2]. However, the existing methods of multistage plowing require high energy costs, which hinders their implementation into production [3][4][5].…”
The paper proposes a new method for multistage plowing that implies loosening bottom soil and subsoil horizon simultaneously, followed by overturning the bottom soil without cutting, which improves the quality of soil cultivation, softens a plow sole and reduces energy costs. Experimental studies confirmed the theoretical relationship for determining the plowing resistance, both of certain working bodies of a section, and of a whole plow. The method proposed for multistage plowing that implies loosening the subsoil provides a decrease in plowing resistance by 8.3-9.8% compared to the existing double-depth plowing followed by loosening the subsoil.

When installed on the frontal plow, the bodies will work in conditions of semi-blocked cutting. The purpose of the study is the theoretical determination of the traction resistance of the frontal plough's cornercutter. The basic principles and methods of classical mechanics, mathematical analysis and statistics were used in this study. Analytical equations for determination of traction resistance of cornercutter beam and plough have been obtained. It is established that traction resistance of frontal plough corners depends on cornersner and plough parameters as well as on physical-mechanical soil properties. At speeds of 1.8-2.3 m/s, traction resistance of the corrugated plough is 0.36-0.39 kN.
“…In this regard, an objective necessity is the fundamental improvement of the technology of soil preparation with the formation turnover and the creation of highly effective technical means for its implementation. R J Godwin [1], F Maiviatov [2,6], V Bulgakov [3], C P Gupta [4], Y P Lobachevsky [5,[10][11][12][13], F Mamatov [7], A Vilde [8] were engaged in the development of smooth plowing plows with the turnover of soil layers into their own furrows, B Tulaganov [9], N K Mazitov [11], S G Mudarisov [12] and other researchers.…”
The process of smooth plowing with the turnover of layers within its own furrow is characterized by high energy costs due to the interaction of the plow body and the plow in conditions of blocked cutting. The purpose of the research is to substantiate the type of the second-rear body of the frontal plow. The proposed front plow for smooth plowing contains twin screw housings, first-row colliders, rear screw right- and left-turning plow housings, second-row colliders. Screw right- and left-turning plow housings are equipped with mirror-mounted screw shortened stabilizing plates. The transverse distance from the field cutoff to the front of the stabilizing plate is greater than the width of the body grip. As a result, the rear bodies work in a semi-open furrow, which helps to reduce the traction resistance of the plow. The results of experimental studies to substantiate the type of rear enclosures are presented. Experiments were carried out with the following types of rear housings: cultured, semi-screw, screw and screw housing with a guide plate. It is established that when performing the rear screw housings and equipping them with guide plates, the quality indicators of the plow fully comply with agro technical requirements. At the same time, the degree of embedding of plant residues and the height of irregularities is 92-95% and 4.3-5 cm, respectively.
