Development of Sensor Based Rotavator Unit For Display of Operational Parameters on Various Soil Conditions 2021-26-0091

Rotavator is an active tillage implement for breaking the Soil and for the preparation of seed bed for cultivation. The Farmers are currently facing problem due to usage of sub optimal speed of Rotavator which results in more fuel consumption, takes more time for completion of operation. Also, the Current Rental models work on Tractor + Implement as rental combination and customer not able to rent Rotavator as a standalone implement due to non-availability of Tracking information such as hours of utilization on Rotavator. Farmers not able to maintain the service periodicity, if oil change not done in prescribed duration then it may result in improper maintenance and breakdown of the Rotavator. To overcome these problems a smart Rotavator developed consists of an electronic unit fitted on the Rotavator shaft to measure the speed of the shaft rotation and in turn convert to Rotavator speed and also able to convert into Hours of usage based on the starting and stopping of the rotavator. These information’s communicated via a Blue tooth system to the mobile app. The information on the speed of the rotavator is also used to measure the optimum travel speed by providing a warning indication if there is a significant variation in optimum speed of the rotavator speed and makes user to operate always at optimum speed results in Fuel saving and improving his pulverization. For serviceability, after every consecutive 50 hours of rotavator operation there is a check oil indication and after every 400 consecutive hours there is change oil indication in the mobile app. These information’s can be communicated to the user through Mobile app and /or through Tractor Digisense app and /Or Display on tractor. The rotavator unit have inbuilt battery (200-300 hours of operations for single charge) and shall be rechargeable using the Mobile charger. As the rotavator is used for both dryland and Puddling hence it is made against dust proof, leak proof and able to withstand dry land and wet land cultivation and vibration as per the farm requirements.

The smart rotavator have been tested for various soil conditions and locations and Field results shows a significant improvement in fuel consumption and performance compared to normal rotavator operations. The area coverage (Acre/ Hour) of 14.08 to 22.67 % for red and black soil conditions respectively was increased and fuel consumption was decreased from 11 % to 7.7 % for black and red soil conditions respectively.
