Adjustable Support Frame for Soil Cultivation Implements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mulching devices attached to vehicles cannot be easily adjusted to avoid obstructing the driver's view during driving mode and are limited to either side or front deployment, lacking flexibility in positioning.
Innovation Solution
A device with pivotably mounted support arms connected to a guide carriage and vehicle, allowing for adjustable positioning using a common hydraulic or pneumatic circuit, enabling the mower or tillage implement to be placed on either side or front of the vehicle without obstructing the driver's view, and allowing for quick position changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the support frame is permanently attached to the vehicle, then the mower can be positioned for working, but the driver's field of vision is obstructed during driving mode
Solution Approach 1:
The support frame is made dynamically adjustable through a telescopic mechanism with guide rails and guide carriages, allowing it to move between extended (working) and retracted (driving) positions. This dynamic positioning resolves the contradiction by enabling the frame to adapt its configuration based on whether the vehicle is in working or driving mode, eliminating vision obstruction during driving while maintaining positioning capability during work.
Solution Approach 2:
The support frame is divided into multiple segments including first and second support arms connected by joints, with guide carriages that can independently move along guide rails. This segmentation allows different parts of the frame to be positioned independently, enabling the mower to be placed on either side or front of the vehicle while allowing retraction to clear the driver's view during driving.
2Adaptability or versatility
If the support frame is permanently attached to the vehicle, then the mower can be used for soil cultivation, but selective and interchangeable positioning on different sides is not possible
Solution Approach 1:
The support frame employs dynamic telescopic mechanisms with guide rails and adjustable joints that allow the mower to be repositioned to different locations (front, left side, right side) based on working requirements. This dynamic adjustability provides selective and interchangeable positioning without requiring multiple permanent mounting configurations, resolving the contradiction between versatility and structural complexity.
3Adaptability or versatility
If the mower position is changed, then flexible positioning is achieved, but the existing drive means must be used for additional movement and alignment
Solution Approach 1:
The existing hydraulic or pneumatic drive circuit of the mower is made multi-functional by connecting it to the telescopic support frame mechanism. The same drive means that normally operates the mower are now also used to power the guide carriages and adjust the support arm positions. This universal utilization of the existing circuit enables position changes without adding separate drive systems, resolving the contradiction between positioning flexibility and circuit complexity.

AI summary
In a device (1) for working soil surfaces (3), in particular for supporting a mower (8) or soil cultivation implement, consisting of a vehicle (4) and a support frame (9) attached to the vehicle (4) on which the mower (8) or soil cultivation implement is attached, and of a hydraulic or pneumatic device (10) by which the mower (8) or soil cultivation implement is set in rotation, for example a mower (8) or the like shall be held laterally next to and/or in front of the vehicle (4).This is achieved by the fact that the support frame (9) is formed from at least one support arm (11, 12), that the support arm (11, 12) is pivotably mounted on a guide carriage (16) by means of a joint (13), that the guide carriage (16) is attached to a guide rail arranged transversely or parallel to the direction of travel (5) of the vehicle (4), and that the support arm (11, 12) and the guide carriage (16) are movable by means of the hydraulic, pneumatic, or electrical device (10) by which the mower (8) is driven.
