MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641050719 A) filed by Dr. S. Arunprasad; Mr. S. Sanjay Kumar; Mr. J. Jeros Valan; and Mr. P. Srinath, Chennai, Tamil Nadu, on April 21, for 'tractor-mounted turmeric and ginger harvester attachment with digging blade, soil separation, and conveyor lift.'
Inventor(s) include Dr. S. Arunprasad; Mr. S. Sanjay Kumar; Mr. J. Jeros Valan; and Mr. P. Srinath.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention a tractor-mounted harvester attachment mechanizes harvesting of turmeric and ginger rhizomes to reduce labour, time and crop damage. The attachment comprises a mounting frame, a digging blade assembly to penetrate and loosen the rhizome zone, a soil separation region, a conveyor assembly to lift and convey rhizomes to a collection region, and a PTO-driven power transmission assembly to drive the conveyor. PTO power is transmitted through a bevel gearbox and belt-pulley system with an operating speed ratio, and the conveyor uses a nylon/rubber belt for gentle handling. Blade declination and thickness are optimized to improve penetration and reduce bruising/cutting of rhizomes. Representative design calculations include a digging force requirement on the order of 4500 N and conveyor drive sizing based on belt tension and pulley radius. Field testing demonstrates harvesting efficiency about 85-90% and reduced labour dependency, with crop damage reduced by operational tuning of blade depth and tractor speed."
