DETERMINATION OF TRACTION RESISTANCE OF THE DISC USING FORMULAS V.P. GORYACHKINA

Abstract

The components of the formula of V.P. Goryachkin are theoretically grounded and experimentally confirmed when determining the traction resistance of a four-row disk cultivator (disk cultivator) on pre-sowing tillage. It is established that the third component of the formula V.P. Goryachkina, taking into account the speed of movement of the soil layer and the shape of the disk working
body, is valid for all types of tillage implements, including disk drives. When carrying out the technological process of soil treatment with a diskator, it is necessary to take into account the area of the segment of the formation processed by each disk of four rows of harrows and the speed of movement of the soil layer. As a result of theoretical studies, we obtained graphs of the dependence of the change in the area of the “mainland” soil layer treated by the disks of the first row of the diskator and their share in
the treatment of the soil layer when the angle of attack of the disks is α=200 , α =300 . From the graphs of the change in the traction resistance of the disk and discator PD-BDM6x4 depending on the depth of the soil cultivation and the angle of attack of the
disks, the minimum and maximum values of the traction resistance of the discator. Knowing the traction resistance of one disc of a harrow, you can determine their number for installation on a diskator for aggregation with tractors of class 30 kN and 50 kN.
