The utilization of electricity energy for supplying vibration power of a rotary vibrating subsoiler from tractor ry

The precision agriculture is one of the best ways to carry out mechanized operations to conserve natural and economic resources. By achieving to this important issue, utilizing a variety of sensors, various hydraulic, electronic and mechanical technologies in agricultural machinery. Control and planning to apply the variable rate application (VRA) 1, especially by solving the problem of required power supply will be provided, on the other hand, the expansion of supplying electricity energy due to easier transmission, high efficiency and intelligent planning capabilities in various industries, especially automotive industry, during a few recent decades show the necessity of its entrance to tractors and agricultural machineries, but the type and amount of electrical power avaliable in tractors is the main limiting factor. In this research, with an overview of the methods of supplying electricity to agricultural tools agricultural equipment, a new method was tested to supply the vibration of an electric vibrating subsoiler. which is based on the design of a DC inverter is with a power input from the tractor battery, which according to it, a pulse width modulation and a potentiometer are responsible for applying the appropriate speed for electromotor and variable vibration frequency, and the subsoiler vibration system frequencies (zero frequency: F1 frequency +18: F2, -18: F3, +36: F4 and -36: F5) was provided with required power up to 1 kW. The results of tillage indicators of a rotary vibrating subsoiler with electricity energy showed that the effect of vibration frequency levels on the draft force and the reduction of the clod mean weight diameter has significant at the level of 5%, so electrifying the agricultural equipment can improve their performance and power supply with inverter design in addition to simplicity and cost reduction, the power supply feature independent of tractor engine speed is very important and efficient for precision agriculture.
