Title : Evaluation parameters afeccting the performance of vibrating vertical tillage equipment - First stage

Abstract :

The purpose of this study was to evaluate alternatives to reduce energy consumption applied to soil clearing. To do this, we developed an experimental device and evaluated the operation of the vibration-induced parameters. System integrated components for on-site evaluation: Frame tool carrier with introduction of three-point hitch and depth control mechanism system: Introduction of three sensors to measure tillage force, torque and frequency of subsoiler vibration Met. The oscillating impact force was applied through the rod and crank mechanism in the subsoiler whose motion was provided by the hydraulic motor. The device evaluation was complemented by a signal regulator and data collection system that allowed the registration of variables of interest such as system traction, penetration, applied torque and vibration velocity. The sensor calibration results showed a system correlation of 95% or more. In the field system verification at different speeds, amplitudes and depths of tillage, the traction force was reduced by up to 50% by using vibration-induced tillage compared to the non-vibration tillage state. This study showed a significant 33% increase in traction and torque magnitude when the working depth increased from 0.30 to 0.40 m. The traction force increased by 21% when the vibration amplitude decreased from 0.0707 to 0.060 m. No significant difference was found when the tractor velocity increased from 1.5 to 2.5 kmh -1. For future research, the device developed makes it possible to determine how tilling amplitude and working depth and vibration frequency affect traction in tilling work.
