Self-Propelled Pineapple Picker with Integrated Cutting and Scraper Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pineapple picking technologies, such as the Chinese patent CN113728794B, rely heavily on manual labor and require additional processing for stalks and tail leaves, which are not effectively removed during the picking process, leading to inefficiencies and increased labor intensity for farmers.
Innovation Solution
A self-propelled picking vehicle for pineapples utilizing a scraper transportation system with a cutting plate and chain conveyor system, equipped with disk blades and a fruit protector, which automatically cuts and collects stalks and tail leaves, reducing manual labor and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual harvesting is used, then labor flexibility is maintained, but labor cost accounts for 40% of total production cost and labor intensity is extremely high
Solution Approach 1:
The picking mechanism is divided into multiple independent components: fruit picking plates for harvesting, disk blades for cutting stalks and tail leaves, and a scraper transportation system for conveying. Each component performs a specific function, allowing the system to achieve high productivity while maintaining manageable complexity through functional segmentation.
2Ease of operation
If traditional picking mechanisms are used, then picking operation is simple, but stalks and tail leaves remain and require additional processing
Solution Approach 1:
The patent combines the fruit picking operation with stalk and tail leaf cutting operations into a single integrated mechanism. The fruit picking plates harvest pineapples while disk blades simultaneously cut the stalks and tail leaves, and the scraper transportation system conveys all processed material in one continuous operation, eliminating the need for separate processing steps.
3Manufacturing precision
If cutting mechanism is added to pickers, then stalks and tail leaves are effectively removed, but device structure becomes more complex
Solution Approach 1:
The scraper transportation system serves multiple functions: it conveys harvested pineapples, transports cut stalks and tail leaves away from the picking area, and supports the cutting mechanism structure. This multi-functionality reduces the need for additional dedicated components, maintaining structural simplicity while achieving precise cutting of stalks and tail leaves.

AI summary
A self-propelled picking vehicle for pineapples based on scraper transportation is provided and includes a baseplate, a driving mechanism, and a propelling mechanism. The driving mechanism is disposed on the baseplate, the propelling mechanism is disposed at a lower end of the baseplate, and the driving mechanism is connected to the propelling mechanism. A front end of the horizontal chain conveyor is provided with a cutting plate. The cutting plate is provided with two disk blades, outer sides of the two disk blades are provided with dividers, and a fruit protector is disposed between the two disk blades. A fruit picking mechanism is disposed on an upper end of the fruit protector. The entire process has achieved automated pineapple picking, efficiency of picking and transportation is improved, and labor intensity of fruit farmers is greatly reduced.
