Olive Tree Plantation Management for Continuous Mechanical Harvesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current olive plantation management methods are not adapted to continuous mechanical harvesting, resulting in low yields, high labor requirements, and inefficiencies, particularly for varieties recognized for olive oil production with controlled designation of origin.
Innovation Solution
A specific olive tree plantation management process involving parallel row planting with collective vertical trellising, divergent stakes, and strategically oriented carpenter branches to facilitate continuous harvesting by straddle machines, optimizing tree spacing and pruning for high-yield, efficient harvesting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional manual or portable tool harvesting methods are used, then labor flexibility is maintained, but harvesting yield and efficiency remain low
Solution Approach 1:
The patent replaces manual labor and portable mechanical tools with a self-propelled straddle harvester that uses mechanical vibrations generated by an exciter mounted on the tractor chassis to detach olives from trees. This substitution dramatically increases harvesting yield while reducing labor requirements, as the machine can continuously move through rows and harvest multiple trees without operator intervention at each tree.
Solution Approach 2:
The straddle harvester is designed as a self-propelled machine that autonomously moves through the orchard rows, positions itself against trees, generates vibrations to detach olives, and collects the fallen fruit without requiring manual repositioning or operation at each tree. This self-service capability enables continuous harvesting operation and significantly improves productivity.
2Productivity
If trunk vibrators are used for mechanical harvesting, then harvesting efficiency improves compared to manual methods, but continuous harvesting is not achieved due to stopping and repositioning requirements
Solution Approach 1:
The patent implements continuous harvesting by designing a self-propelled straddle harvester that maintains motion throughout the orchard rows. The machine continuously generates vibrations through its mounted exciter, detaches olives from multiple trees in sequence, and collects fruit without stopping or requiring repositioning operations, thereby eliminating time losses associated with traditional trunk vibrator methods.
Solution Approach 2:
The invention combines the vibration generation system, fruit detachment mechanism, and fruit collection system into a single integrated self-propelled platform. The exciter mounted on the tractor chassis generates vibrations that propagate to the trees, while the same machine's structure and collection mechanisms simultaneously gather the detached olives, enabling continuous operation without separate repositioning steps.
3Quantity of substance
If dense plantation spacing is used to increase yield per hectare, then land utilization improves, but mechanical harvesting becomes difficult due to machine maneuvering constraints
Solution Approach 1:
The patent employs a self-propelled straddle harvester with adjustable and adaptable mechanical characteristics that can operate in densely spaced plantations. The machine's dynamic design allows it to navigate narrow rows, adjust its positioning against trees, and maintain effective vibration transmission despite close tree spacing, thereby enabling mechanical harvesting in high-density plantations that would otherwise be inaccessible to traditional equipment.
4Productivity
If harvesting is performed during daytime with traditional methods, then safety is maintained, but harvesting cannot be performed at night due to operator safety concerns
Solution Approach 1:
The self-propelled straddle harvester operates autonomously without requiring human operators to be present in the orchard during harvesting operations. The machine independently navigates rows, generates vibrations, detaches olives, and collects fruit, eliminating exposure of workers to nighttime hazards such as poor visibility, wildlife, and accidental injuries, thereby enabling safe nighttime harvesting operations.

AI summary
The invention relates to a method for controlling the planting of olive trees for the continuous mechanical harvesting of the olives using harvesting machines, characterized by the following steps: planting parallel rows of olive tree saplings (Jo) with a spacing between the tree trunks (TR) and a spacing between the rows (R1, R2, R3); placing trellising (stakes (P) and wires (F)) on each row; placing divergent supports (T1, T2) for each tree; attaching two divergent branches (CH1, CH2) of each tree, which are arranged in a single vertical plane and in the vertical plane of the row to which said tree belongs, onto a pair of supports; removing other branches of said tree; adapting the shape of the foliage (AF) of the trees so as to impart a configuration flattened in alignment with the rows thereto; maintaining said configuration by periodically pruning the trees until the latter reach maturity and bear fruit; and removing the supports and the trellising when the trees are fully grown.
