Planter Opener Depth Control Using GPS and Gauge Wheel Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional agricultural planters lack effective systems for controlling and measuring the depth of trenches opened during planting, leading to inconsistent seed placement and potential yield reduction due to insufficient depth adjustment mechanisms.
Innovation Solution
The implementation of a depth adjustment assembly with primary and secondary adjustment mechanisms, including actuators and gear systems, that allow for precise control of furrow depth by limiting the upward travel of gauge wheels and modifying the position of the depth adjustment body, enabling accurate and adaptable trench depth management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional planters use only maximum depth adjustment apparatus, then the planter structure remains simple, but the actual planting depth cannot be maintained due to soil conditions and insufficient downpressure
Solution Approach 1:
The system uses depth sensors to detect actual trench depth during operation and provides feedback to the control system, which then automatically adjusts the planter depth to maintain the desired planting depth despite variations in soil conditions and terrain
Solution Approach 2:
The patent replaces manual mechanical depth adjustment with an automated electro-hydraulic or electro-pneumatic actuation system controlled by a microprocessor-based control unit, enabling precise depth control without manual intervention
2Reliability
If sensors are added to detect trench depth loss, then depth monitoring capability is improved, but the actual planted depth is still not determined
Solution Approach 1:
The control system uses sensor feedback not only to detect trench depth loss but also to calculate and determine the actual planted depth by integrating depth measurements over time and comparing them against the desired depth profile
Solution Approach 2:
The patent introduces an intermediary calculation layer in the control system that processes raw sensor data and converts it into meaningful actual depth information, acting as a mediator between the physical sensing layer and the decision-making layer
3Manufacturing precision
If precise depth control is implemented, then seed placement consistency is improved, but the system requires complex actuators and adjustment mechanisms
Solution Approach 1:
The depth adjustment mechanism serves multiple functions: it controls maximum depth, maintains actual planting depth, compensates for terrain variations, and adapts to different soil conditions, reducing the need for separate specialized mechanisms for each function
Solution Approach 2:
The system transitions from static pre-set depth adjustments to dynamic real-time depth control, where the planter depth is continuously adjusted during operation based on actual field conditions detected by sensors

AI summary
An agricultural planting system for controlling the depth of an opener device comprising: an agricultural planter; an opener device mounted on the agricultural planter for engaging the ground of a field; a gauge wheel mounted on the agricultural planter for rotating on the ground of the field; a GPS device coupled to the agricultural planter, the GPS device configured to determine a location of the agricultural planter in the field; and a controller in electrical communication with the agricultural planter and the GPS device, the controller having predetermined settings associated with a map of the field, the controller being configured to select a relative elevation of the opener device and the gauge wheel based at least in part on the location determined by the GPS device, and produce, based on the location, a signal for adjusting the depth of engagement into the ground of the opener device.
