Optimization of the kinematic mode of operation of the tractor-driven tillage tool

A traction-driven tillage tool with low traction resistance has been developed. A decrease in the tractive resistance of the implement is achieved by transferring the main share of the power consumed by the implement to the process of loosening the soil through the tractor power take-off shaft (PTO) to the drive needle discs, which in turn create a pushing force. The efficiency of the technological process of soil cultivation depends on the kinematic mode of operation of each row of disk working bodies of the tractiondrive tillage implements. To optimize their kinematic mode of operation, a multifactorial experiment was carried out, which made it possible to establish the optimal values of such factors as the kinematic parameters of the 1st and 2nd rows of needle disks at the set operating speed of the unit

Soil tillage energy efficiency increase

Tillage energy efficiency increase is one of the important tasks in improving the profitability and sustainability of agricultural production. The paper proposes to increase cultivation energy efficiency due to the use of traction-drive tilling implement with active working bodies, not creating a high traction resistance and not requiring a large towing weight of aggregated tractor. The analysis of the energy efficiency of soil cultivation using traction-driven tilling implements with active working bodies has been carried out, and theoretical dependences of the coefficient of efficiency of a traction-driven machine-tractor unit has been obtained. The possibility of increasing the efficiency of the unit by reducing slipping of the tractor wheels and losses on rolling of the unit has been determined, which has been achieved by transferring part of the power through the power take-off shaft (PTO) of tractor to the drive working bodies of tilling implement, which compensate for traction resistance of the implement and create a pushing force, reducing the resistance to rolling
