Pivoting Ground Guide Redirects Soil Uphill
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Soil erosion on sloping terrain is exacerbated by wind and water, leading to topsoil migration downhill, rendering sensible use of soil impossible and causing damage, as existing devices distribute loosened soil evenly, contributing to erosion rather than mitigating it.
Innovation Solution
A device with a pivoting ground guide element mounted on the holding arm allows the loosened soil to be thrown uphill and against the direction of erosion, using a flat ground guide device that can be swiveled and locked to redirect soil movement, and an actuator system for adjustable positioning of the ground guide elements, enabling the soil to be redeposited where it was before erosion began.

1Productivity
If loosening shares work the soil in strips and distribute earth evenly on the surface, then soil loosening is achieved, but soil erosion worsens due to topsoil migration downhill
Solution Approach 1:
The ground guide device inverts the natural downhill movement of loosened soil by redirecting it uphill through a pivoting mechanism. The ground guide element is positioned and angled to catch soil moving downhill and redirect it in the opposite direction, effectively counteracting erosion forces and returning topsoil to its original location.
Solution Approach 2:
The device applies preliminary anti-action by intercepting loosened soil before it can migrate downhill and cause erosion. The ground guide device is positioned to catch soil immediately after loosening and redirect it uphill, preventing the harmful erosion process from occurring in the first place.
2Object-affected harmful factors
If a fixed ground guide device is used to redirect soil uphill, then erosion is counteracted, but device complexity increases
Solution Approach 1:
The ground guide device employs a pivoting mechanism that allows dynamic adjustment of the ground guide element's angle and position. This dynamic capability enables the device to adapt to varying terrain conditions and soil flow patterns while maintaining the core function of redirecting soil uphill, avoiding the need for overly complex fixed structures.
Solution Approach 2:
The ground guide device is designed to perform multiple functions: it redirects soil uphill to prevent erosion, can be adjusted to different angles for various terrain conditions, and works in conjunction with the loosening shares. This multi-functionality reduces the need for separate dedicated erosion control devices, simplifying the overall system.
3Adaptability or versatility
If the ground guide device is made adjustable with actuators, then adaptability to different terrain improves, but device complexity and cost increase
Solution Approach 1:
The pivoting mechanism provides dynamic adjustability of the ground guide element's position and angle, allowing the device to adapt to different terrain conditions. This mechanical dynamic adjustment is simpler than fully actuated systems while still providing the necessary versatility for various field conditions.

AI summary
The device (10) has an obliquely forward loosening coulter (13) that is provided with a blade (16) and a support arm (15). A floor diffuser (20) is supported on support arm. The floor diffuser pivotably mounted about a running axis (21) is provided at a distance above the blade. The floor diffuser is raised to loosen the soil depending on the tilt angle of blade.
