Working Device Position Holding After Auto-Stop in Field Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural machines face inefficiencies in work efficiency and soil quality due to the need to manually adjust the working device's position after automatic operation, leading to delays and soil marks when resuming agricultural jobs.
Innovation Solution
An agricultural machine equipped with a position detector, lifting device, and automatic operation controller that maintains the working device in a work position even after automatic operation stops, allowing for immediate resumption of agricultural tasks without manual adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lifting device moves the working device to a retracted position after automatic operation ends, then the working device is positioned for safety during manual operation transitions, but the agricultural job cannot be immediately resumed and work efficiency decreases
Solution Approach 1:
The system performs preliminary positioning by keeping the working device in the work position during automatic operation and only retracting it when the agricultural job is actually resumed. This preliminary maintenance of the work position eliminates the need for repositioning delays when transitioning to manual operation.
Solution Approach 2:
The lifting device dynamically adjusts the working device position based on operational context - maintaining the work position during automatic operation and transitioning to retracted position only when necessary for manual operation safety, optimizing both efficiency and safety.
2Manufacturing precision
If the working device is separated from the soil and then contacts the soil again, then the mark on the soil disappears, but the number of manual operation steps increases and work efficiency decreases
Solution Approach 1:
The system maintains continuous useful action by keeping the working device in the work position throughout automatic operation and only retracting when the agricultural job is resumed. This continuous positioning eliminates interruptions and maintains soil quality without increasing manual operation steps.

AI summary
An agricultural machine includes a traveling vehicle body, a position detector to detect a position of the traveling vehicle body, a lifting device to link a working device to the traveling vehicle body, and an automatic operation controller to perform an automatic operation to cause the traveling vehicle body to travel and cause the working device to perform an agricultural job based on a travel route and the position of the traveling vehicle body. The lifting device is operable to, during the automatic operation, place the working device in a work position in which the working device performs the agricultural job, and the automatic operation controller is operable to cause the lifting device to keep the working device in the work position even after stopping the traveling vehicle body and/or the working device to end the automatic operation at a location short of an unworked area of the agricultural field.
