Santrifüj Gübre Dağıtma Makinesinde İki Farklı Tahrik Sisteminin Karşılaştırılması.

Many agricultural machines (rotary tiller, planting, fertilizing, pesticide, irrigation, shearing, baling, silage machines etc.) are operated by getting motion from the tractor power takeoff. The motion from the tractor power takeoff (PTO) is transferred to the agricultural machines via an articulated shaft (the intermediate shaft). In motion transmission with an articulated shaft, in addition to mechanical adversities, there are risks of noise, vibration and entanglement which will affect the operator's health and safety during operation. In this study, a hydraulic system, which is formed as an alternative to the movement given by the PTO to the fertilizer broadcaster is connected to the hydraulic system of the tractor with open circuit hydraulic system. In the case of both motion transmissions (articulated shaft and hydraulic motor), operating conditions of the machine; fertilizer distribution uniformity, tractor fuel consumption, noise and vibration values were determined and compared. While mean noise level in mechanical system were determined as 91.01 (dBA) on the machine and 81.93 (dBA) in the tractor cabine, mean noise level in hydraulic system were determined as 81.15 (dBA) on the machine and 71.85 (dBA) in the tractor cabine. While the total vibration acceleration of the mechanical system were determined as 68.36 m s-2 on the machine, 3.23 m s-2 on the tractor driver seat, the total vibration acceleration of the hydraulic system were determined as 60.02 m s-2 on the machine and 2.64 m s-2 on the tractor driver seat. It has been determined that the machine with hydraulic system does not differ significantly from the mechanical system in terms of fertilizer distribution uniformity, but it is more suitable in terms of fuel consumption and noise and vibration values that important for the health of the tractor driver. Operating the Fertilizer broadcaster machines with a hydraulic system can be an alternative system in terms of ergonomics that can increase both the efficiency and effectiveness of the machine. Works can be done to operate other machines driven from the PTO with hydraulic motor applications. [ABSTRACT FROM AUTHOR]
