Hollow Pull Frame for Agricultural Implement Conduit Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fertilizer application implements face interference and motion limitations due to hydraulic lines and pull frames, which wear out and restrict the range of motion of moving parts, hindering efficient fertilizer distribution.
Innovation Solution
A pull frame design with a hollow portion that accommodates conduits, allowing them to pass through while maintaining clearance from moving parts, and is removably coupled to the main frame, enabling adjustable geometry to reduce interference and enhance motion range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If hydraulic lines are fastened to the tool frame at various points, then the hydraulic lines can be secured and organized, but the hydraulic lines may interfere with and contact moving parts, thereby wearing the hydraulic lines and limiting the range of motion of the moving parts
Solution Approach 1:
The hydraulic lines are extracted from the tool frame structure and routed through the hollow pull frame, separating them from the moving parts of the tool bar assembly. This extraction eliminates the interference between hydraulic lines and moving components while maintaining secure positioning.
Solution Approach 2:
The pull frame serves as an intermediary structure that carries the hydraulic lines between the tractor and the tool bar assembly. By positioning the hollow pull frame to extend over the tool bar assembly, the hydraulic lines are mediated through a protected pathway that prevents contact with moving parts.
2Strength
If the pull frame is rigidly coupled to the main frame, then the structure is stable and strong, but the pull frame may interfere with the moving parts of the fertilizer application implement, thereby further limiting the range of motion of the moving parts
Solution Approach 1:
The pull frame is segmented into a removable mounting portion and the main hollow frame structure. This segmentation allows the pull frame to be detached when interfering with tool bar operation, maintaining structural strength when needed while enabling freedom of motion during fertilizer application operations.
Solution Approach 2:
The pull frame transitions from a static rigid structure to a dynamic removable structure. The mounting portion can be attached or detached based on operational requirements, allowing the system to adapt between transport mode (where stability is needed) and working mode (where range of motion is needed).

AI summary
An agricultural implement includes a tool bar assembly configured to couple to a main frame of the agricultural implement and a pull frame. The tool bar assembly includes a first tool with a height that is adjustable relative to a soil surface. The pull frame includes a hitch assembly configured to be coupled to a work vehicle, a mounting portion configured to be removably coupled to the main frame of the agricultural implement, and a hollow portion that extends over the first tool bar between the hitch assembly and the mounting portion while the tool bar assembly and the pull frame are coupled to the main frame. The hollow portion is configured to accommodate one or more conduits.
