Agricultural Parking Support with Rotational Sliding Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounted machines for agriculture face challenges in safely parking due to parking supports that do not protrude beyond the lower edge of the frame, making hitching difficult and potentially leading to tipping over.
Innovation Solution
The parking supports are designed with a sliding guide element allowing limited rotational movement, enabling them to be positioned far enough away from the machine's center of gravity, with helical guide slots and spring elements for secure pivoting and locking, facilitating easy transition between parking and working positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the parking supports are positioned far enough away from the center of gravity for safe parking, then the parking stability is improved, but the hitching difficulty increases because the supports do not protrude beyond the lower edge of the frame
Solution Approach 1:
The parking supports are made dynamically adjustable through a telescopic mechanism with rotational capability. The supports can extend outward to protrude beyond the frame edge for easy hitching, then retract and rotate to positioned far from the center of gravity for stable parking. This dynamic adjustment resolves the contradiction between needing protrusion for hitching and needing retraction for stability.
Solution Approach 2:
The parking supports utilize a nested telescopic structure where inner tubes slide within outer tubes. This nesting allows the supports to compactly store within the frame structure when retracted for stable parking, while extending outward when needed for hitching operations, effectively resolving the spatial contradiction.
2Device complexity
If the parking supports are fixed in position, then the structural simplicity is maintained, but the ability to achieve both safe parking distance and easy hitching is lost
Solution Approach 1:
Rather than creating a complex multi-component adjustable system, the patent implements a relatively simple telescopic mechanism with rotational joint that provides both extension and rotation capabilities. This maintains structural simplicity while enabling the supports to adapt their position for different operational requirements.
Solution Approach 2:
The parking supports serve multiple functions through a single integrated mechanism: they provide structural support, enable easy hitching when extended, and ensure stable parking when retracted and rotated. This multi-functionality reduces the need for separate components, maintaining structural simplicity while achieving position adaptability.
3Device complexity
If manual positioning of parking supports is required, then the mechanism simplicity is maintained, but the ease of operation deteriorates
Solution Approach 1:
The telescopic parking supports are designed to be self-positioning through a guided mechanism. When force is applied to extend or retract the supports, the built-in guides and constraints automatically direct the movement along the correct path, combining extension with rotation. This eliminates the need for complex manual positioning operations while maintaining mechanism simplicity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration ensures safe parking and easy operation by allowing the parking supports to be positioned correctly and securely locked, preventing incorrect operation and ensuring the machine remains stable during transport and use.
Implementation Method 1
at least one spring element moving the parking support in the direction of the retracted working position is arranged between the sliding guide element and the parking support
Implementation Method 2
the rotary sliding guide is designed as a helical guide slot and/or groove arranged in the wall of the sliding guide element

AI summary
An attached machine, in particular a spreading machine, with three-point linkage elements, a frame, and at least one parking device, wherein the parking device has at least one parking support arranged in at least one sliding guide element located on the lower part of the frame and which can be moved into at least one extended parking position and into at least one retracted position for the working position. To create an advantageous parking device, it is provided that the parking support is arranged relative to the sliding guide element with at least one sliding guide that allows a limited rotational movement of the parking support relative to the sliding guide element when the parking support is extended and retracted.Simplified operation for moving the support stand into the intended position is achieved by arranging at least one spring element between the sliding guide element and the support stand, which moves the support stand towards its retracted working position. To securely lock the support stands in their respective positions, at least one locking element is provided between the sliding guide element and the support stand, fixing the support stand in its designated position. It is particularly advantageous if this measure is combined with the preceding measure by providing the corresponding spring element between the sliding guide element and the support stand.
