Work Vehicle Bucket Spill Plate Design for Load Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bucket designs for work vehicles fail to adequately protect the couplings of the booms and the front glass of the cab from load spillage while ensuring visibility and preventing damage during loading and operation.
Innovation Solution
A bucket design featuring a spill plate with specific edge configurations and side guards that direct falling load away from critical components, combined with a spill plate formed from a single plate for enhanced rigidity and visibility, positioned to prevent load from falling on the booms and cab.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the spill guard is cut out to such an extent that it is possible visually to check the load stuff in the bucket even when the bucket is raised up, then the visibility of the bucket is improved, but load stuff may fall down from the bucket and collide with the front glass of the cab, causing damage
Solution Approach 1:
The spill guard is divided into multiple segments including side guard portions and a front guard portion. The side guard portions extend rearward from the front of the bucket, and the front guard portion connects these side portions, creating a segmented structure that provides protection while allowing visibility through the gaps between segments.
Solution Approach 2:
Different portions of the spill guard have different properties: the side guard portions provide protection against load stuff falling from the sides, while the front guard portion specifically protects the front glass area. The structure transitions from a solid plate to a segmented design with varying degrees of openness in different locations.
2Device complexity
If the spill guard is cut out minimally to secure visibility of the end portions during traveling, then the structure remains simple and protective, but it is not possible to visually check the load stuff in the bucket when the bucket is held up higher than the cab
Solution Approach 1:
The spill guard is divided into multiple segments including side guard portions and a front guard portion. The side guard portions extend rearward from the front of the bucket, and the front guard portion connects these side portions, creating a segmented structure that provides protection while allowing visibility through the gaps between segments.
3Reliability
If the spill guard is designed to protect against load spillage, then the couplings of the booms are protected, but the visibility of the bucket and its contents is reduced
Solution Approach 1:
The spill guard is divided into multiple segments including side guard portions and a front guard portion. The side guard portions extend rearward from the front of the bucket, and the front guard portion connects these side portions, creating a segmented structure that provides protection while allowing visibility through the gaps between segments.

AI summary
A bucket for a work vehicle comprises a bucket main body portion, left/right boom attachment portions, and a spill plate. The left/right boom attachment portions are adhered to the rear surface of a basal plate, to the left/right sides of the center of the basal plate in the lateral direction, respectively. The spill plate includes a first spill plate portion and a second spill plate portion. In a top view, the second spill plate portion includes a forward edge line extending in the left and right directions from a center of the bucket main body portion in the lateral direction, and first left/right edge lines extending to first/second connection points rearward and leftward/rightward from first/second front ends, which are the left/right ends of the forward edge line, respectively. In a top view, the first spill plate portion includes a second left edge line, a second right edge line, a third left edge line, and a third right edge line. The second left/right edge lines are connected to the first left/right edge line at the first/second connection points, extend rearward and leftward/rightward, or leftward/rightward, from the first/second connection points to third/fourth connection points, and incline forwarder than the first left/right edge lines, respectively. The third left/right edge lines are connected to the second left/second right edge lines at the third/fourth connection points, extend rearward and leftward/rightward from the third/fourth connection points, incline more rearward than the second left/right edge lines, respectively. Moreover, the first/second connection points are positioned to the left/right sides of first right/left end positions, which are the right/left end positions of the left/right boom attachment portions, respectively.
