Reversible Plow Stabilizer Segmentation for Ground Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reversible plows suffer from insufficient ground clearance due to the kinked design of the stabilizer, affecting both transport and working journeys.
Innovation Solution
The stabilizer is designed in two parts with a straight stabilizer element and a spur gear, chain, or belt drive, ensuring both elements are in a common horizontal plane, maintaining the same height distance from the ground during operation and transport, eliminating the kinked design and associated ground clearance issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the stabilizer is designed in a kinked configuration to connect the chassis to the hitch, then the plow frame can be stabilized during operation, but the ground clearance of the plow is insufficient during both transport and working journeys
Solution Approach 1:
The stabilizer is divided into two separate parts: a first stabilizer part connected to the hitch and a second stabilizer part connected to the chassis. These parts are connected through a cardanic connection, allowing each part to be optimized independently for its specific function while maintaining overall stability.
Solution Approach 2:
The cardanic connection introduces an additional degree of freedom in the vertical dimension, allowing the stabilizer parts to accommodate height differences between the hitch and chassis without compromising stability. This enables the plow to maintain adequate ground clearance while preserving stabilizer functionality.
2Device complexity
If the stabilizer is designed as a single rigid component, then the structure is simple, but the ground clearance is reduced due to the kinked design
Solution Approach 1:
The stabilizer is segmented into two parts with a cardanic connection between them, which adds some structural complexity but eliminates the kinked design. This segmentation allows the stabilizer to maintain a straighter configuration that preserves ground clearance while still providing effective stabilization.
3Adaptability or versatility
If the plow frame is raised using the three-point linkage of the tractor, then the plow can be adjusted between working and transport positions, but the entire bearing load must be absorbed by the hydraulic system
Solution Approach 1:
The support wheel acts as an intermediary element between the plow frame and the ground. It carries a portion of the bearing load during transport and position adjustment, relieving the hydraulic system from having to support the entire plow weight. This reduces the force requirements on the hydraulic lift system while maintaining position adjustability.

AI summary
The invention relates to a reversible plow (1) with a rotatable and/or pivotable plow frame (6) that can be supported on a mounting frame (2) for connecting the reversible plow (1) to an agricultural tractor, and with rows of plowshares (7, 8) with plow bodies (9) arranged on opposite sides of the plow frame (6), wherein by means of a rotary movement of the plow frame (6) initiated via a drive device, either one or the other row of plowshares (7, 8) can be selectively moved into its operating position or into its out-of-service position, and with a support wheel (19) connected to the plow frame (6) via a chassis (20) that supports the plow frame (6) on the ground in the operating position of one row of plowshares (7, 8) and the plow frame (6) in the operating position of the other row of plowshares (7, 8).wherein the chassis (20) of the support wheel (19) is connected to the mounting frame (2) via a stabilizer (24) and the plow frame (6) is pivotable about a pivot or swivel axis around the stabilizer (24), the chassis (20) and the support wheel (19). To improve this reversible plow and increase ground clearance, the stabilizer is designed in two parts: a straight stabilizer element (24) and a stabilizer part having a spur gear, (27) chain or belt drive, wherein the stabilizer element and the stabilizer part have approximately the same height above the ground as the plow frame in the working position of the cables.
