Linkage Assembly Transporting Material Without Axis Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional material handling machines are inefficient in transporting material from the front to the rear of the machine frame, often requiring unnecessary rotations about multiple axes, which reduces loading efficiency.
Innovation Solution
A material handling machine with a linkage assembly comprising guide rails, booms, and lift mechanisms that allow the loader bucket to move directly from the front to the rear of the machine frame, minimizing axis rotations and enhancing efficiency through a prismatic joint transport system and coordinated actuator control.

If conventional material handling machines use multiple axis rotations for transporting material, then the machine can achieve material transport capability, but the loading efficiency decreases due to unnecessary rotations and movements
Solution Approach 1:
The machine is divided into functionally independent modules: a fixed base structure with guide rails, and a movable linkage assembly that can be positioned independently. This segmentation allows the linkage to transport material along guide rails without requiring the entire machine or multiple axes to rotate, thereby improving loading efficiency while reducing unnecessary rotational movements
Solution Approach 2:
The invention transitions from conventional multi-axis rotational movement to linear translational movement along guide rails. By introducing a third dimension (vertical guide rails) and using prismatic joints for linear motion, the system eliminates the need for complex multi-axis rotations, reducing mechanical complexity while maintaining material transport capability
2Productivity
If wheel loaders engage in Y movement for loading, then the machine can load material, but it requires rotation about vertical axis which reduces loading efficiency
Solution Approach 1:
Instead of rotating the entire machine or linkage assembly about the vertical axis to achieve Y-movement loading, the invention inverts the approach by keeping the base fixed and using movable linkages that translate along guide rails. This inversion eliminates vertical axis rotation while achieving the same loading function, thereby improving loading efficiency and simplifying operation
