Agricultural Attachment Drawbar Pivoting for Transport Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural attachments face challenges in simplifying their use and transport, as they often require separate transport trolleys or complex mechanisms to accommodate road travel, leading to increased costs, space requirements, and operational inefficiencies.
Innovation Solution
An attachment designed to be coupled to an agricultural machine for field cultivation, featuring a frame with an adjustable drawbar that pivots between a transport position for road travel and a working position, allowing it to be supported by the machine without additional axles, thus eliminating the need for a separate transport trolley and enabling efficient switching between field and road operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the attachment is coupled to the agricultural machine for field cultivation, then the attachment can be supported by the machine, but the width of the attachment exceeds the maximum permissible road width
Solution Approach 1:
The attachment is designed with a rotatable mechanism that allows it to change its orientation dynamically. During field cultivation, the attachment operates in its working position with full width for functionality. During transport, the attachment can be rotated 90 degrees to reduce its effective width to comply with road regulations, thus resolving the contradiction between field cultivation capability and road width compliance
Solution Approach 2:
The attachment serves multiple functions: it can be used for field cultivation in its normal orientation and for road transport in a rotated orientation. This multi-functionality allows the same attachment structure to satisfy both agricultural operational requirements and road transport regulations without needing separate equipment
2Length of moving object
If a transport trailer is used to carry the attachment for road travel, then the width problem is solved, but additional costs and space requirements arise
Solution Approach 1:
The solution extracts the need for a separate transport trailer by integrating the transport capability directly into the attachment itself. The attachment's own structure includes the means to be transported (rotation mechanism and coupling points), eliminating the requirement for additional external transport equipment and reducing overall system complexity
Solution Approach 2:
The attachment combines its working function and transport function into a single integrated unit. The same structure that performs field cultivation also serves as the transport platform when rotated, merging what would traditionally require separate equipment (attachment and trailer) into one unified system
3Ease of operation
If the attachment remains attached to the agricultural machine for road travel, then transport is simplified, but the weight of the attachment rests on the machine requiring an additional axle
Solution Approach 1:
The attachment system is designed to be dynamically reconfigurable between two states: during field work, the attachment is connected to and supported by the agricultural machine; during road transport, the attachment is disconnected from the machine and supported on its own chassis. This dynamic reconfiguration allows the weight to be transferred from the agricultural machine to the attachment's self-supporting structure, eliminating the need for additional axles on the machine
4Length of moving object
If the attachment is rotated 90 degrees on the transport trailer, then the width problem is solved, but the attachment must be unloaded and reloaded before each use which is time-consuming
Solution Approach 1:
The attachment is equipped with self-contained coupling and support mechanisms that enable it to be easily connected to and disconnected from the agricultural machine without requiring complex loading/unloading operations. The attachment's own chassis and coupling points allow for quick attachment/detachment operations, significantly reducing the time loss compared to traditional trailer-based systems that require full loading and unloading cycles

AI summary
The invention relates to an implement (1) for field cultivation, which is configured to be coupled to and supported by an agricultural machine in a working mode and to be towed by a tractor in a transport mode, resting on a chassis (50) separate from the agricultural machine, and comprising a frame (2) which is coupled to the agricultural machine at least indirectly in working mode. To simplify the use and transport of an implement for an agricultural machine, the invention provides that the implement has a drawbar (10) connected to the frame (2), which, in a transport position corresponding to the transport mode, projects from the frame (2) at one drawbar side (4) for coupling to the tractor, and which can be adjusted by at least one actuator (38) into a working position corresponding to the working mode, in which it is at least partially displaced towards the frame (2) compared to the transport position.
