Agricultural Machine Selective Ground Work Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural machines, such as rice transplanters, are not designed to perform irregular ground work, making it inconvenient to form regions with and without ground work in central areas of agricultural fields.
Innovation Solution
An agricultural machine equipped with a traveling machine body and a controller that acquires work information indicating whether ground work is to be performed in specific areas of the field. The controller selectively actuates ground working mechanisms based on this information, allowing for the precise control of ground work operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all ground working mechanisms operate in the entire agricultural field, then ground work coverage is maximized, but the ability to perform irregular ground work with specific regions is lost
Solution Approach 1:
The working width of the agricultural machine is divided into multiple independent ground working mechanisms (first, second, third, and fourth mechanisms). Each mechanism can be independently controlled to operate or stop based on the specific region being traversed. This segmentation allows selective operation of individual mechanisms to create irregular ground work patterns while maintaining overall productivity.
Solution Approach 2:
The control system dynamically adjusts the operation state of each ground working mechanism based on real-time position information and pre-stored work information. The controller determines which mechanisms should operate in which regions, enabling dynamic adaptation to irregular ground work requirements while maintaining high productivity through optimized mechanism utilization.
2Adaptability or versatility
If ground working mechanisms are stopped in certain regions, then irregular ground work patterns are achieved, but overall work efficiency decreases
Solution Approach 1:
Work information indicating the desired ground work pattern is stored in advance in the controller before the machine enters the field. The position information of the machine is also pre-established. This preliminary preparation allows the controller to immediately determine which ground working mechanisms should operate in each region without real-time decision delays, maintaining high work efficiency while achieving flexible ground work patterns.
Solution Approach 2:
The controller continuously receives position information from the position information acquisition unit and compares it with the pre-stored work information to determine the appropriate operation state for each ground working mechanism. This feedback loop ensures that mechanisms are activated or stopped at the correct locations, achieving precise irregular ground work patterns without unnecessary delays.
3Productivity
If multiple ground working mechanisms operate simultaneously across the entire field, then productivity is maximized, but control complexity increases
Solution Approach 1:
The control system is designed to independently control each ground working mechanism based on its corresponding region. The controller receives position information and selectively activates specific mechanisms (first, second, third, or fourth) based on which region the machine is traversing. This segmented control approach manages complexity by treating each mechanism-region pair as an independent control unit rather than managing all mechanisms simultaneously.
Solution Approach 2:
The controller serves multiple functions: acquiring position information, retrieving pre-stored work information, determining operation states for multiple different ground working mechanisms, and executing appropriate control commands. This multi-functional design consolidates control complexity into a single universal control unit rather than requiring separate control systems for each mechanism.

AI summary
An agricultural machine is enabled to perform irregular ground work with more convenience. An agricultural machine (1) includes a traveling machine body (21) equipped with a working implement (10) including a plurality of ground working mechanisms (42) to perform ground work; and a controller (3) to acquire work information indicating whether or not the ground work is to be performed in each of a plurality of areas (A) of an agricultural field (H). The controller (3) is configured or programmed to selectively activate each of the plurality of ground working mechanisms (42) based on the work information when the traveling machine body (21) travels in the agricultural field (H) and when the working implement (10) passes through an area (A) of the plurality of areas (A).
