Baling Press Slope Compensation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bale wrapping processes are disrupted on uneven terrain due to bale misalignment and slipping, leading to incomplete or failed wrapping, and existing solutions either compromise machine design or fail to address diagonal slope gradients.
Innovation Solution
A slope compensation device with transverse slope adjustment actuators tilts the bale former and wrapper relative to the direction of travel, allowing for incline compensation across contour lines, combined with pitch inclination adjustments to handle gradients, maintaining a constant angular position between the bale shaper and wrapper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a transfer conveyor is provided to convey bales from the bale forming chamber to the wrapping table, then the baling press can handle height differences caused by slope compensation, but the machine becomes bulky and expensive in the longitudinal direction
Solution Approach 1:
The patent combines the bale former and wrapper onto a common machine frame that can be tilted as a unit. This merging eliminates the need for a separate transfer conveyor mechanism, reducing machine bulkiness and cost while maintaining the ability to handle height differences through slope compensation of the entire assembly.
Solution Approach 2:
The tiltable machine frame serves multiple functions: it compensates for slope-induced height differences, maintains the bale formation and wrapping processes aligned with the ground, and eliminates the need for separate transfer mechanisms. This multi-functionality resolves the contradiction by achieving adaptability without increasing device complexity.
2Reliability
If the wrapping table is tilted to compensate for slope gradients, then bales can be wrapped on a level surface, but only slope gradients in the direction of travel can be compensated, not diagonal or contour line gradients
Solution Approach 1:
The patent employs dynamic slope compensation by making the entire machine frame tiltable rather than just the wrapping table. This dynamic adjustment allows the whole system to adapt to various slope conditions, improving versatility while maintaining wrapping reliability through active level compensation during operation.
3Manufacturing precision
If the bale former height is adjusted relative to the ground, then sufficient gradient to the wrapping table can be ensured, but the bale can still slip on the wrapping table or fail to transfer reliably when driving diagonally
Solution Approach 1:
By merging the bale former and wrapper onto a common tiltable frame, the patent ensures that both components move together during slope compensation. This eliminates relative movement and slipping between components while maintaining proper ejection gradients, thus improving transfer reliability without sacrificing precision.

AI summary
The present invention relates to a baler with a chassis for ground support, a collector for gathering crop material from the ground, a bale former for forming the gathered crop material into bales, a wrapper for wrapping the bale with a net, film, or the like, and a slope compensation device for tilting the wrapper and/or the bale former against a slope. According to the invention, the slope compensation device comprises at least one lateral tilt actuator for tilting the bale former and/or the wrapper against a slope transverse to the direction of travel.
