Combine Harvester Discharge Transition Control During Auto Travel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic traveling systems for combine harvesters interrupt reaping work prematurely, leading to unworked rows and inefficient grain discharge due to fixed transition positions based on storage amount, which can be inappropriate for skilled operators.
Innovation Solution
An automatic traveling method and system that allows for dynamic adjustment of transition positions from reaping to discharge traveling based on operator input, using a combine harvester equipped with an automatic traveling control part, discharge traveling control part, and a transition position change mechanism responsive to discharge operation inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the transition position is set based on storage amount of grain, then the discharge timing is automatically controlled, but the automatic traveling is interrupted in the middle of reaping work causing unworked rows and inability to travel smoothly
Solution Approach 1:
The transition position is made dynamically adjustable rather than fixed. The system allows the operator to change the transition position from the automatically determined position (based on grain storage amount) to a manually specified position, enabling flexible adaptation to different working conditions and operator preferences while maintaining automatic control capabilities.
2Quantity of substance
If the automatic traveling is interrupted for discharge traveling, then grain discharge can be performed, but the combine harvester cannot travel smoothly due to unworked rows
Solution Approach 1:
The operator can preliminarily adjust the transition position before discharge traveling is executed. By changing the transition position to an appropriate location that avoids unworked rows, the system prepares the discharge operation in advance, ensuring smooth traveling during both reaping and discharge phases.
3Device complexity
If the transition position is fixed based on storage amount, then automatic control is simplified, but it cannot accommodate skilled workers' judgment for smooth reaping work
Solution Approach 1:
The control system is designed to serve multiple functions: it automatically determines the transition position based on grain storage amount for simplified operation, while also allowing manual adjustment to accommodate skilled workers' judgment and preferences. This multi-functionality makes the system adaptable to different operator skill levels and working conditions.

AI summary
A combine harvester includes a control device and a portable terminal. The control device functions as an automatic traveling control part for controlling the combine harvester to perform automatic traveling on the basis of an automatic traveling route comprising a plurality of set straight traveling routes and a plurality of set turning routes, and as a discharge traveling control part for controlling the combine harvester to perform discharge traveling from a predetermined transition position on the automatic traveling route to a discharge position. The portable terminal includes the control device, and the control device functions as the transition position change part for changing, as the transition position, the first transition position that is set on the basis of the storage amount of harvested grain, to the new second transition position in response to the operation of the discharge transition operation part such as the discharge advance button and the discharge postpone button.
