Adjustable Compression Rollers for High-Density Baler Bales
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current balers rely on belt tension to regulate bale density, which decreases durability and is not effective in increasing bale density, and there is a need for improved methods to form high-density bales.
Innovation Solution
A baler with a compression assembly featuring adjustable opposing compression rollers that pre-compress crop material, synchronized with a pick-up assembly and bale chamber, using pressure and speed sensors with a controller to maintain optimal pressure and synchronization for forming high-density bales.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If belt tension is increased to regulate bale density, then bale density is improved, but belt durability decreases
Solution Approach 1:
The compression function is segmented from the belt system and assigned to dedicated compression rollers. The belt merely conveys material while compression rollers perform the density-regulating compression, dividing the workload and preventing belt overload.
Solution Approach 2:
Compression rollers act as an intermediary mechanism between the belt conveyor and the bale formation process. Instead of the belt directly compressing material (which damages the belt), the rollers mediate the compression function while the belt maintains its conveyance role.
2Quantity of substance
If compression pressure is increased to form high density bales, then bale density is improved, but crop material may be damaged
Solution Approach 1:
The compression rollers feature adjustable gaps and variable compression forces that can be dynamically adapted to different crop materials and desired density levels. This allows optimization of compression pressure to achieve high density while preventing excessive damage to the crop material.
Solution Approach 2:
The compression parameters (gap distance, rotation speed, compression force) are made variable and adjustable. By changing these parameters, the system can achieve high density bales while adapting to different material types and preventing excessive damage through controlled compression levels.

AI summary
An improved baler and a method of using the improved baler to produce high density bales. The baler comprises a pick-up assembly configured to pick-up crop material; a compression assembly comprising at least one pair of opposing compression rollers configured to generate a pressure on the crop material as it passes between the compression rollers; and a bale chamber, wherein the pre-compressed crop forms a bale. The compression rollers define an adjustable gap therebetween. By adjusting the gap, pressure exerted on the crop material as it passes between the compression rollers may be controlled, resulting in bales of varying density.
