Reversible Plough Pivoting Axis Intersection for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reversible semi-mounted plows are complex, prone to constructive weaknesses, and lack stability during use, particularly when transitioning between plowing positions.
Innovation Solution
The plow design features a pivoting assembly where the axis of the front pivoting joint intersects the axis of the pivoting assembly, allowing the rear part to automatically raise during turning, ensuring stability and simplifying kinematics, with additional support provided by a second pivot bearing and an articulated connection that can include a ball joint for enhanced guidance and rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex pivoting mechanism with multiple components is used to lift and position the rear part of the main frame, then the plough can prevent ploughing bodies from contacting the ground during turning and position the rear part parallel to the ground during transport, but the construction becomes complex, structurally weak, and unstable
Solution Approach 1:
The patent removes the complex tilting lever, cylinder, and spacer components from the pivoting mechanism, retaining only the essential front pivoting joint and rear pivoting joint bearings. This extraction of unnecessary components simplifies the construction while preserving the core functionality of lifting and positioning the rear part during turning and transport operations.
Solution Approach 2:
Instead of using a complex mechanism to actively lift and position the rear part, the patent inverts the approach by allowing the rear part to follow the natural motion of the front part through the articulated connection. The simpler bearing arrangement passively guides the turning motion, eliminating the need for active lifting components while maintaining stability.
2Reliability
If a complex pivoting mechanism with multiple components is used to lift and position the rear part of the main frame, then the plough can prevent ploughing bodies from contacting the ground during turning, but the construction becomes structurally weak
Solution Approach 1:
The patent removes unnecessary structural components such as the tilting lever, cylinder, and spacer that weakened the overall structure. By retaining only the essential front and rear pivoting joint bearings, the construction becomes stronger while maintaining the required functionality for preventing ploughing bodies from contacting the ground during turning.
3Reliability
If a complex pivoting mechanism with multiple components is used to lift and position the rear part of the main frame, then the plough can position the rear part parallel to the ground during transport, but the construction becomes unstable in use
Solution Approach 1:
The patent removes the tilting lever, cylinder, and spacer components that created instability during use. The simplified bearing arrangement with only the front and rear pivoting joints provides stable, predictable motion throughout the operating cycle, including during transport when the rear part needs to be positioned parallel to the ground.

AI summary
The invention relates to a reversible plow (1) of the mounted or semi-mounted type with a carriage (2) comprising a front part (3') of the main frame (3) and a rear part (3") of the main frame (3), each of which carries plough bodies (4), these two parts of the main frame (3' and 3") being respectively integral with the front (5') and rear (5") parts of a connecting frame (5) mutually connected by an articulated joint (6), said plow (1) also comprising a support frame with a fixed front part (7') and a tilting rear part (7"), connected together by a pivoting assembly bearing (8), the front part (5') of the connecting frame (5) being connected to the fixed front part (7') of the support frame by a front pivoting articulation bearing (9) and the rear part (5") of the connecting frame (5) being connected to the tilting rear part (7") of the support frame (7) by a rear pivoting articulation bearing (10),The front and rear pivoting articulation bearings (9 and 10) form reversing guide bearings. This plow (1) is characterized in that the axis of the front pivoting articulation bearing (9) intersects the axis of the pivoting assembly bearing (8) at the level of said pivoting assembly bearing (8).
