R.K. AGRAWAL, S.K. JAIN and SADASHIV SHIRSAT. 2017. Design model of coconut harvesting machine. Green Farming Vol. 8 (6) : 1406-1409 ; November-December, 2017
ABSTRACT
The study revealed that during manual harvesting 7.23 per cent time is required for climbing 36 trees, 3.69 per cent time is required for coming down from trees and 89.07 per cent time was required as rest time in between two climbing. The designed model of coconut harvesting machine consists of base frame assembly, telescopic assembly and cutting assembly. The base frame consists of switch, battery stand, transportation wheels and attachment for revolving telescopic assembly. The observations on physical loss of nuts showed the maximum damage of 5.78 per cent and 8.69 per cent when tender nuts of 8 months maturity stage were dropped from 7 and 10 m heights respectively. A model of coconut harvesting machine was developed by considering the growth parameters of tree, physical characteristics of coconuts, pedicel density, circular blade parameters viz. speed of dc motor, setting angle of teeth and number of teeth, cutting force, power, and cutting time.
