Planter Seed Tank Access Platform and Stowable Ladder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional agricultural implements, such as planters, pose difficulties in accessing and servicing upper components like seed tanks due to the need for operators to climb on the tool bar or support structure, which is inconvenient and challenging for handling heavy loads.
Innovation Solution
A platform and ladder system is integrated into the implement, allowing secure access and standing on upper levels for extended periods, with the platform extending between seed tanks and a retractable ladder ensuring interference-free operation, enabling easy loading and inspection of seeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operators climb on the tool bar or implement support structure to access seed tanks, then access to upper components is achieved, but operator safety and convenience deteriorate
Solution Approach 1:
A platform is introduced as an intermediary structure between the ground and the seed tanks. The platform is supported by legs that extend upward from the implement frame, providing a stable intermediate standing surface. This mediator allows operators to access seed tanks safely without directly climbing on the tool bar or support structure, thus resolving the contradiction between ease of access and operator safety.
2Ease of operation
If a fixed platform and ladder system is added to the implement, then operator access to upper components is improved, but interference with normal implement operation and ground clearance worsens
Solution Approach 1:
The ladder is made movable rather than fixed. It can be positioned in different locations along the platform and adjusted to accommodate different operating conditions. This dynamic positioning allows the ladder to be moved out of the way when not in use or when implement operation requires clear space, thus resolving the contradiction between improved operator access and adaptability to different operational requirements.
3Adaptability or versatility
If the ladder base is positioned high to avoid ground interference, then implement versatility is improved, but operator access difficulty increases
Solution Approach 1:
Instead of positioning the ladder base high to avoid ground interference, the platform legs extend upward from a lower position on the implement frame. This vertical dimensionality change allows the ladder base to be positioned at a convenient height for operator access while the platform itself provides the necessary elevation for seed tank access, thus resolving the contradiction between ground clearance and ease of ladder access.

AI summary
A towed implement, such as a planter, is provided with an operator platform and ladder for mounting the platform. The platform may be supported on the implement frame, and extends from a position rear of the ground-engaging row units to a position immediately adjacent to seed tanks. The platform may extend between the seed tanks to allow for loading of seeds, inspection of the tanks, removal of debris, and so forth. The ladder for accessing the platform may be fixed or stowable in a raised position. Handrails may be provided on either side of the platform, forward of the platform, and adjacent the ladder for stabilizing the operator during servicing of the implement.
