Hay Bale Cleaning Trailer with Conveyor and Brush System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for handling and transporting bales of hay are labor-intensive and unsafe due to uneven stacks and protruding strands of hay, which can cause injuries and inefficiencies in packing and unpacking processes.
Innovation Solution
A trailer equipped with a conveyor belt system and brushes that can move and clean bales of hay, allowing for efficient loading and unloading by guiding the bales onto the trailer using motor-powered conveyor belts and optionally hydraulic motors to manipulate the brushes for precise cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual handling and stacking of hay bales is used, then labor flexibility is maintained, but labor intensity and safety risks increase significantly
Solution Approach 1:
The hay bale handling system performs cleaning, stacking, and securing operations automatically without human intervention. The conveyor belt moves bales automatically, brushes clean them autonomously, and the stacking mechanism positions them without manual labor, making the system self-sufficient in performing tasks that would otherwise require workers.
Solution Approach 2:
Manual mechanical handling by workers is replaced with an automated mechanical system consisting of conveyor belts, hydraulic lifts, and robotic stacking mechanisms. This substitution eliminates the need for human physical labor while maintaining or improving handling efficiency and safety.
2Manufacturing precision
If bales are stacked manually without cleaning, then processing time is reduced, but stacking quality and safety decrease due to uneven surfaces and protruding strands
Solution Approach 1:
The brushes clean the hay bales before they are stacked, removing protruding strands and creating uniform surfaces in advance. This preliminary cleaning action ensures that when bales are stacked, they form even, stable piles without requiring additional adjustment or rework later.
Solution Approach 2:
The cleaning and stacking operations are merged into a single integrated process. The conveyor belt simultaneously transports and positions bales while brushes clean them, combining what could be separate sequential operations into one efficient workflow that reduces total processing time.
3Extent of automation
If traditional friction belt thrower mechanism is used, then automation level increases, but bale handling precision and safety decrease due to unpredictable bale trajectories
Solution Approach 1:
The unpredictable friction-based throwing mechanism is replaced with a controlled hydraulic lifting and placement system. This substitution provides precise, predictable bale positioning while maintaining automation, eliminating the reliability issues associated with friction-based throwing that results in scattered, uneven stacking.

Function Achieved in This Case
The solution significantly reduces labor costs and improves safety by ensuring even stacking and efficient handling of bales, minimizing the risk of injury and streamlining the packing and unpacking process.
Implementation Method 1
a conveyor belt and a plurality of brushes, the conveyor belt to move the bale of hay onto the bale trailer or off of the bale trailer
Implementation Method 2
an upper portion of the trailer has a motor coupled to the conveyor belt and the plurality of brushes

AI summary
A bale cleaning truck is presented. A flatbed trailer has a conveyor belt for moving one or more bales off the trailer. There are one or more brushes for cleaning a hay bale as it travels down the trailer where at least two vertical brushes that are mounted vertically on the sides of the trailer. A roof brush is attached to the top of the trailer and the final brush is mounted above the trailer to clean the top of the bale. Pumps for operating the brushes and the conveyor belt are hydraulic.
