Semi-Mounted Reversible Plow Linkage for Fast Furrow Offset Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing semi-mounted reversible plows require complex and time-consuming manual adjustments to switch between furrow and on-land working positions, with limited adjustment ranges due to the interdependence of actuators for the offset rocker and front furrow rocker.
Innovation Solution
The implementation of independent offset and adjustment actuators allows for easy, remote-controlled adjustments between working positions, enabling a broader range of transverse distance settings by actuating each independently, combined with a linkage gear mechanism for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual relocation of actuators and locking mechanisms is used to adjust between working positions, then the plow can change positions, but the adjustment process becomes complex and time-consuming
Solution Approach 1:
The system uses self-servicing actuators that automatically maintain their position without requiring manual intervention. The actuators are designed to self-position and self-lock, eliminating the need for operators to manually relocate components between furrow and on-land working positions.
Solution Approach 2:
The patent extracts the complex manual adjustment mechanism and replaces it with automated actuators. By removing the need for manual locking and relocation operations, the system simplifies the adjustment process while reducing the time required to switch between working positions.
2Adaptability or versatility
If the adjustment actuator is relocated to different points on the offset rocker or front furrow rocker, then different transverse distances can be achieved, but the device complexity increases
Solution Approach 1:
The actuators are designed with universal mounting capabilities that allow them to function at multiple positions without requiring physical relocation. The actuator design incorporates multi-position mounting features that enable the same actuator to achieve different transverse distances by adjusting its mounting position along the rockers, rather than requiring different actuators for different positions.
Solution Approach 2:
The system employs dynamically adjustable actuator positions that can be reconfigured without permanent relocation. The actuators can be quickly repositioned along the rockers and secured, allowing the same actuator to serve multiple functions at different positions, thereby reducing overall device complexity while maintaining versatility.
3Reliability
If the position of the offset rocker relative to the front furrow rocker is locked manually, then the position can be fixed, but the adjustment process becomes more complex
Solution Approach 1:
The locking mechanism is designed as a self-servicing system that automatically maintains the relative position of the offset rocker and front furrow rocker. The actuator incorporates an integrated locking feature that self-activates when the desired position is reached, eliminating the need for separate manual locking operations while ensuring position stability.
Solution Approach 2:
The patent merges the positioning and locking functions into a single integrated actuator operation. The actuator simultaneously achieves the desired transverse distance and locks the relative position of the rockers in one continuous motion, rather than requiring separate positioning and locking steps, thereby simplifying the adjustment process while maintaining reliability.

AI summary
A semi-mounted reversible plow with a headstock for attachment to a tractor, a stabilizer which is connected to the headstock and on which a plow frame carrying two rows of plow bodies is mounted by way of at least a front turning arm in a manner rotatable about a horizontal turning axis, wherein an offset rocker in a rotatable manner to the turning arm and a front furrow rocker connected in an articulated manner to the offset rocker and in a rotatable manner to the plow frame, on the other hand, are arranged between the plow frame and the turning arm, and wherein the rockers can be moved by an adjustment actuator to positions causing different transverse distances between the headstock and in the direction of travel of the foremost plow body, such that the semi-mounted reversible plow is configured to selectively assume a furrow working position and an on-land working position.
