Rotatable Receiving Table for Bale Stack Wagon
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bale transport vehicles with non-rotatable, non-tiltable receiving tables struggle to efficiently stack and transport mid-size or big bales, as they cannot rotate or tilt bale layers relative to each other, leading to an unstable and inefficient load.
Innovation Solution
A rearward-hinged and forward-hinged, rotatable and tiltable receiving table system is introduced, allowing for the selective lifting, tilting, and rotating of bale layers 90 degrees, which can be easily converted onto a stack load table to criss-cross tie bale layers together, using hydraulic actuators and simple attachment methods like pins, clips, and bolts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a non-rotatable, non-tiltable receiving table is used, then the structure is simple and reliable, but the bale stacking efficiency and stability are poor
Solution Approach 1:
The receiving table is transformed from a static structure to a dynamic one by adding rotation and tilting capabilities. The table can now rotate about a vertical axis and tilt about a horizontal axis, allowing flexible adjustment of bale layers to create stable criss-cross stacked configurations, thereby improving stacking efficiency while maintaining reasonable structural complexity through controlled degrees of freedom.
2Stability of the object's composition
If a rotatable and tiltable receiving table is added, then bale layer stability and load cohesion are improved, but the device complexity increases
Solution Approach 1:
The receiving table mechanism is segmented into independent rotational and tilting subsystems. The rotation function is separated from the tilting function, each with their own pivot axes and control mechanisms. This segmentation allows the complex stability-enhancing capability to be broken down into manageable, independently controllable movements that work together to secure bale layers in stable criss-cross configurations.
3Adaptability or versatility
If the receiving table can rotate 90 degrees, then bale layer orientation and criss-cross tying capability are improved, but the mechanism complexity increases
Solution Approach 1:
The receiving table is designed with pre-configured rotation capability about a vertical axis, allowing the operator to pre-orient bale layers at specific angles (including 90 degrees) before stacking. This preliminary orientation adjustment enables the creation of stable criss-cross configurations without requiring complex real-time adjustment mechanisms during the stacking process, thereby achieving high adaptability with controlled mechanism complexity.

AI summary
An improved rearward-hinged and forward-hinged, rotatable and tiltable receiving table for a agricultural bale transport vehicle that selectively tilts and rotates a layer of bales resting thereupon 90 degrees relative to a preceding bale layer on the transport vehicle to criss-cross tie a load of bales (a plurality of layers of bales) together in a load stack offloaded from the transport vehicle to the field for later pickup and movement or deposit in a bale storage area. Preferably, the bale transport vehicle is a mid-size or big bale stack wagon having a Mil-Stak® bale loader previously installed or concurrently being installed. The invention enables the lifting, tilting, rotating, and depositing of one mid-size or big bale or a plurality of mid-size or big bales from a rearward-hinged and forward-hinged bale receiving table of the bale transport vehicle onto a rear-hinged stack load table for consolation into a load with other layers of bales for transport from the field. The invention allows selective 90 degree rotation of a layer of bales relative to a preceding layer of bales of the bale stack on the rear-hinged stack load table.
