Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large cultivators with front and rear rolling supports face challenges in maneuverability, especially when turning, due to the complexity and cost of control mechanisms and pivot joints required for rotational support.
Innovation Solution
An agricultural implement design featuring a main frame with soil working tools, pivotally connected first and second support frames with rolling ground supports, and a control mechanism using a control lever and synchronization links to adjust the height and rotation of the support frames synchronously, allowing for easy maneuverability and cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the front and rear rolling supports are made rotatable about a vertical axis to improve maneuverability, then the agricultural implement can turn more easily, but the control mechanism becomes complicated and expensive
Solution Approach 1:
The patent removes the rotatable pivot joint from the support frame, extracting the complex rotational control mechanism. Instead, the support frame is fixedly connected to the main frame, eliminating the need for complicated pivot controls while maintaining maneuverability through the leveling mechanism.
Solution Approach 2:
The patent introduces a leveling mechanism with adjustable support arms as an intermediary system. This mechanism mediates between the main frame and the rolling supports, providing height adjustment and ground leveling functionality without requiring complex rotational pivot joints.
2Ease of operation
If the front and rear rolling supports are made rotatable about a vertical axis to improve maneuverability, then the agricultural implement can turn more easily, but the pivot joint is subject to wear and requires maintenance
Solution Approach 1:
The patent removes the rotatable pivot joint entirely from the support frame connection, extracting the source of wear and maintenance requirements. The fixed connection eliminates the moving pivot joint while maintaining structural integrity.
Solution Approach 2:
The leveling mechanism with adjustable support arms provides self-adjusting functionality, allowing the operator to manually level the implement without requiring complex rotational mechanisms that would wear out and need maintenance.
3Manufacturing precision
If the distance between front and rear rolling supports is increased to improve working depth control, then the agricultural implement can better control soil working depth, but the agricultural implement becomes more difficult to maneuver
Solution Approach 1:
The patent makes the support arms dynamically adjustable in length and angle, allowing the distance between front and rear rolling supports to be modified. This dynamic adjustment capability enables the operator to optimize both working depth control and maneuverability depending on operational requirements.
Solution Approach 2:
The patent allows changes in the geometric parameters of the support system, specifically the length and angle of the support arms. By adjusting these parameters, the implement can achieve better working depth control when needed while maintaining maneuverability when the arms are in their adjusted positions.

AI summary
An agricultural implement comprises a main frame (11), which carries a plurality of soil working tools (32), a first support frame (12a), which is pivotally connected to the main frame (11) via a first support frame joint (21a) and which carries at least one first rolling ground support (31a), such as a wheel or a roller, a control lever (13) rotatably connected to the main frame (11) via a control lever joint (22), a support frame control link (14) rotatably connected to the control lever via a first support frame control link joint (23a) and which is pivotally connected to the support frame (12) via a second support frame control link joint (23b) so that rotation (V1) of the control lever (13) around the control lever (22) provides rotation (V2) of the first support frame (12a) relative to the main frame (11), wherein the control lever (13) is rotatable in a first direction of rotation (V1) so that the first support frame control link joint (23a) can pass a line (C1) through rotation centers of the control lever joint (22) and the second support frame control link joint (23b) and wherein the first support frame (12a), when the first support frame control link joint (23a) passes the line (C1), changes direction of rotation (−V2).
