Abstract:

A laboratory test-rig for groundnut planter was developed for testing and calibrating the pneumatic seed metering mechanism. The experimental test rig mainly consists of main frame, seed hopper, seed metering system, power transmission system and sticky belt system. The metering unit is incorporated with a vertical seed plate held in a vacuum retaining chamber to singulate the seeds. A dial type vacuum gauge was provided in order to record the variation in suction pressure. A sticky belt was used to simulate the field surface during laboratory investigation. Rotational velocity of metering disc, suction pressure and hole size were chosen as the operating parameters. The developed pneumatic metering unit was tested in the laboratory for groundnut seeds based on miss index, multiple index, quality of feed index and mean seed spacing for every treatment combinations. The rotational velocity of metering disc and forward speed of grease coated belt was varied with the help of variable drive controller with necessary motor arrangements.
