Automated Round Bale Ejection With Terrain-Aware Vehicle Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-propelled baling vehicles face challenges in automatically positioning and ejecting round bales to prevent them from rolling away, as existing systems lack efficient automated control for maneuvering and placement post-bale formation.
Innovation Solution
A self-propelled baling vehicle equipped with a control system that includes a processor and memory device, capable of determining a proposed ejection location, maneuvering the vehicle to that location, ejecting the bale, and returning to the original position, utilizing independent rear drive wheels and sensors for terrain and topographical data to optimize bale placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated control system is implemented for bale ejection, then operational efficiency is improved and operator intervention is reduced, but device complexity increases
Solution Approach 1:
The control system integrates multiple functions including terrain detection, vehicle positioning, ejection timing control, and post-ejection maneuvering into a single automated system. The controller receives input from terrain sensors and autonomously coordinates the drive system and baling system to achieve optimal bale placement without requiring separate manual operations for each function.
Solution Approach 2:
The system uses its own terrain sensors and control mechanisms to automatically determine optimal ejection points and execute the necessary vehicle maneuvers. The baler essentially serves itself by autonomously selecting placement locations and positioning the vehicle appropriately without external operator input.
2Reliability
If vehicle maneuvering is automated to optimize bale placement, then the likelihood of bales rolling away is reduced, but the complexity of the control system increases
Solution Approach 1:
The system continuously monitors terrain conditions using sensors and uses this feedback to dynamically adjust vehicle positioning and ejection timing. The controller processes real-time terrain data to determine optimal ejection locations and automatically maneuvers the vehicle to those locations, creating a closed-loop control system that adapts to changing field conditions.
Solution Approach 2:
The system performs preliminary terrain assessment and vehicle positioning before bale ejection occurs. By detecting optimal ejection locations in advance and maneuvering to those positions beforehand, the system ensures that bales are always deposited in stable locations, preventing rolling issues before they occur.
3Reliability
If the baler maneuvers to position bales for optimal placement, then bale stability is improved, but time is lost during maneuvering
Solution Approach 1:
The system integrates vehicle maneuvering with the baling operation itself, performing positioning actions during normal vehicle travel between windrow sections. Rather than stopping and repositioning after each bale is formed, the baler continuously moves forward, using its mobility to position itself optimally for each ejection event, thereby maintaining continuous productive action.

AI summary
A self-propelled baling vehicle for forming a bale of material includes a drive system for propelling the baling vehicle, a baling system for forming the bale, and a control system coupled to the drive system and the baling system. The control system includes a controller configured to determine a proposed location for ejection of the bale, operate the drive system to maneuver the baling vehicle from a first position to a second position for ejection of the bale at the proposed location, operate the baling system to eject the bale at the proposed location, and operate the drive system to maneuver the baling vehicle back to the first position.
