Abstract

For promotion of PISTACHIO export, investigation concerning mechanized harvesting to improve hygiene in harvest is necessary. In this relation, for harvesting PISTACHIO by tree trunk shaker, initially and in another research work, an EXPERIMENTAL TRUNK SHAKER had been designed and developed by the same author, which was then optimized and tested in this research. The initial EXPERIMENTAL TRUNK SHAKER suffered from some shortcomings some of which could be mentioned as: 1- Clamping to the trunk being tedious. 2- Shaker handling 3-Time consuming process of attaching and detaching of the shaker to the tree trunk, free to move shaker arm and adjustment of shaker arm being stepwise as against being continuous 4- And finally non-gentle shaking of the tree. Those shortcomings were observed, taken into account and then overcome in the process of optimization to a PISTACHIO harvester machine, which was put to test in Rafsanjan. Evaluation of the machine was carried out through a completely randomized design with 40 trees and at a 40 mm stroke and 20 HZ frequencies. A comparison of results between the two apparatuses revealed that the difference in percentage of shedding as well as in time taken for attaching and detaching of the shakers from the tree was significant (p<0.01). This experiment revealed that the tree trunk shaker PISTACHIO harvester with a 77.9% of shedding and time requirement (for attaching to and detaching from the tree) of 15.5 seconds as compared to 30 sec for the former was better fit for PISTACHIO harvesting. This indicated that many of the previous problems and shortcomings had been overcome due to increase in weight, and an addition of attaching clamp, transport wheels and damper to the harvester.
