Potato Planter Slope Compensation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing potato planting machines face challenges with tuber placement on sloping terrain, leading to defects and irregular spacing due to rolling tubers, which complicates the laying process and requires operator intervention.
Innovation Solution
A potato planting machine equipped with a complex control unit and multiple sensors that monitor tuber separation and inclination, allowing for immediate compensation through actuators, enabling adaptive control and reduced operator intervention by directly adjusting conveyor belts or bucket conveyors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional conveyor devices are used on sloping terrain, then the laying process becomes complicated and requires operator intervention, but the basic conveyor structure remains simple
Solution Approach 1:
The patent implements a feedback control system where sensors detect the actual position and orientation of the conveyor device on sloping terrain, and this information is fed back to the control unit. The control unit then automatically adjusts the conveyor parameters to compensate for the slope, eliminating the need for operator intervention while maintaining reliable tuber placement.
Solution Approach 2:
The control system performs self-adjustment based on sensor inputs without requiring external operator intervention. The system automatically detects slope conditions and adjusts the conveyor operation parameters accordingly, making the system self-sufficient in handling varying terrain conditions.
2Ease of operation
If multiple sensors and actuators are added for automatic control, then operator intervention is reduced, but the device complexity increases
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated electronic control system. Sensors electronically detect terrain conditions and conveyor status, and the control unit electronically actuates the actuators to adjust the conveyor, substituting the entire manual mechanical adjustment process with an automated electro-mechanical system that reduces operator burden.
3Manufacturing precision
If the conveyor device is tilted to compensate for slope, then the laying process improves, but the device structure becomes more complex
Solution Approach 1:
The patent makes the conveyor device dynamically adjustable rather than fixed. The conveyor's tilt angle and other parameters can be automatically changed in real-time based on terrain conditions detected by sensors, allowing the system to adapt to varying slopes while maintaining precise tuber spacing through controlled movement and positioning.

AI summary
A potato planter has a machine frame that is particularly accessible to a towing vehicle in the area of a hitch. A singulation device, which interacts with an upper tuber hopper, is mounted on this frame for planting at least one row. A conveying assembly with circulating belts, cups, or similar discharge elements allows individual tubers to be picked up from the hopper and fed individually into a furrow formed in the soil. The planter concept according to the invention provides that at least the conveying assembly that receives the tubers can be adjusted largely automatically to its target state(s) in response to changing intake and/or planting parameters.
