Silage Gripper Segmented Frame for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing silage withdrawal grippers for lifting trucks experience instability and reduced transportation capability due to the center of gravity displacement when the holder is hinged forward, leading to inefficient silage handling and transportation.
Innovation Solution
The silage withdrawal gripper design incorporates a main frame with a secondary frame that allows the silage carrier to hinge independently, maintaining the main frame's orientation during dumping, thereby preventing center of gravity displacement and ensuring stable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the holder is hinged forward with respect to the lifting arm to release silage, then the silage can be dumped into the container, but the center of gravity of the silage withdrawal gripper is displaced further away from the truck body, leading to instability and reduced transportation capability
Solution Approach 1:
The silage withdrawal gripper is divided into functionally independent segments: the holder (23) that can hinge forward to release silage, and the main frame (21) that maintains stable orientation. The secondary frame (130) acts as an intermediate segment that allows the holder to move independently without affecting the main frame's position, thus resolving the contradiction between dumping capability and stability.
2Productivity
If the holder is hinged to an upper portion of the silage carrier to enable silage release, then the silage can be effectively dumped, but the center of gravity is displaced further away from the truck body, causing unstable situations
Solution Approach 1:
The invention introduces a new degree of freedom by allowing the holder to hinge forward with respect to the main frame through the secondary frame mechanism. This dimensional independence enables the holder to perform its dumping function while the main frame maintains its stable position, effectively separating the two conflicting requirements in different spatial dimensions.

AI summary
A silage withdrawal gripper (100) comprises: a main frame (110), adapted for coupling to a lifting arm of a lifting truck; a silage carrier (120) hinged to the main frame (110); at least one controllable carrier actuator (125) for controlling the hinge position of the silage carrier (120) with respect to the main frame (110); a hingeable holder (140) adapted to cooperate with the silage carrier (120) for gripping and holding silage; wherein the holder (140) is hinged (146) to the main frame (110), at a position above the hinge axis (124) of the silage carrier (120); and wherein the silage withdrawal gripper (100) further comprises at least one controllable holder actuator (125) for controlling the hinge position of the holder (140) with respect to the main frame (110).
