Sugarcane Billet Debris Extraction Using Airflow and Drum Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural harvesters face challenges in effectively separating debris, such as dust and dirt, from harvested sugarcane billets, leading to inefficiencies in the processing and storage of clean billets.
Innovation Solution
A debris removal system for agricultural harvesters, featuring an extractor housing with an airflow device and a drum positioned within an airflow channel, which uses airflow to separate debris from billets and directs it to a housing outlet, with a motor-driven drum to manage debris flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If debris is allowed to contact the airflow device for separation, then debris removal effectiveness is improved, but component lifespan is reduced
Solution Approach 1:
A rotating drum is introduced as an intermediary component between the airflow device and debris. The drum captures debris from the airflow and transports it to a collection container, preventing direct contact between debris and the airflow device while maintaining effective debris separation.
2Device complexity
If a simple airflow device is used for debris separation, then device complexity is reduced, but debris contact with the device increases
Solution Approach 1:
The separation system is segmented into distinct functional components: an airflow device for generating separating airflow, a rotating drum for capturing and transporting debris, and a collection container for storing debris. This segmentation allows each component to perform its specific function while protecting the airflow device from debris damage.

Function Achieved in This Case
Enhances the separation of debris from sugarcane billets, prolonging the lifespan of system components and improving the efficiency of the harvesting process by ensuring clean billets are delivered to storage.
Implementation Method 1
An airflow device is configured to generate an airflow from the housing inlet towards the airflow device and the airflow is configured to separate the debris from billets of a crop material

AI summary
A debris removal system for an agricultural harvester can include an extractor housing defining a housing inlet, a housing outlet, and a passage. The extractor housing can further define an airflow channel for directing debris through the extractor housing from the housing inlet to the housing outlet. An airflow device can be configured to generate an airflow from the housing inlet towards the airflow device. The airflow can be configured to separate the debris billets of a crop material. A drum can be positioned at least partially within the airflow channel and between the housing inlet and the passage. The debris within the airflow channel can be directed by the drum toward the housing outlet.
