Excavator Bucket Row Switching for Uniform Automatic Digging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing excavation systems face inefficiencies in automatic operations due to unnecessary excavation when objects are fully inserted or when the amount of remaining objects is small, leading to suboptimal use of excavation resources.
Innovation Solution
An excavation system with a controller that sets a border forward of the upper slewing body and controls the bucket to continue excavation on the same row if full, or change rows if not full, optimizing excavation efficiency by uniformly distributing the remaining objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If excavation is performed along an excavation row from front to rear until completion, then the excavation operation can be automated, but unnecessary excavation operations occur when excavation objects are fully inserted into the bucket or when the amount of remaining objects is small
Solution Approach 1:
The controller continuously monitors the position of the bucket relative to the border and the completion status of excavation operations. Based on this feedback, the controller dynamically determines whether to continue excavation on the current row or switch to a new row, thereby avoiding unnecessary excavation operations and improving overall excavation efficiency while maintaining automation
Solution Approach 2:
The excavation system dynamically adjusts the excavation row selection based on real-time conditions. When the bucket completes excavation and is located forward of the border, the system continues on the same row; when the bucket is on or rearward of the border, the system switches to a new row. This dynamic adaptation eliminates wasted operations and optimizes productivity
2Quantity of substance
If a plurality of excavation operations are performed on a certain excavation row, then more excavation objects can be collected, but useless operations occur when the amount of excavation objects remaining on the excavation row is small
Solution Approach 1:
The controller uses feedback from the bucket position relative to the border to determine when to stop excavation on the current row. When the bucket reaches or passes the border position after completing an excavation operation, the controller switches to a new row, preventing useless excavation operations on rows with insufficient remaining objects while maximizing collection of available material
Solution Approach 2:
The system performs excavation operations partially on each row, stopping when the border condition is met rather than exhaustively clearing every row. This approach prevents excessive excavation actions on rows with small remaining amounts, reducing wasted time while still collecting sufficient excavation objects

AI summary
A controller (30) of an excavation system controls a bucket (15c) to excavate an excavation object (O) along an excavation row (C). In a case where the bucket (15c) is located forward (X1) of a border (53) at completion of one excavation performed by the bucket (15c), the controller (30) causes the bucket (15c) to perform next excavation without changing the excavation row (C). In a case where the bucket (15c) is located on the border (53) or rearward (X2) of the border (53) at the completion of one excavation performed by the bucket (15c), the controller (30) changes the excavation rows (C) and causes the bucket (15c) to perform the next excavation.
