Agricultural Distributor Frame with Angled Support Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional agricultural spreading machines, such as seed drills, obstruct the driver's rear view due to their supporting structure, and the tillage implements are not easily detachable for independent use.
Innovation Solution
The support frame of the storage container is designed to be supported by outer support elements on the two shoes, eliminating the need for lower support elements, allowing for a clear rear view and enabling the tillage implement to be detached for separate use, with a stable and torsion-resistant structure that absorbs the weight of the reservoir and distributes it through the support shoes and upper link.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional supporting structure with vertical support elements is used below the bearing block, then the storage container is stably supported, but the driver's rear view is obstructed
Solution Approach 1:
The invention removes the vertical support elements that were previously positioned below the bearing block and between the support shoes. By extracting these obstructing components, the design achieves unobstructed rear visibility while maintaining support stability through the alternative configuration of support shoes and upper link
Solution Approach 2:
The support function is relocated from a vertical arrangement (below the bearing block) to an horizontal/external arrangement (support shoes at the underside and upper link at the top). This dimensional redistribution eliminates visual obstruction while preserving structural stability
2Stability of the object's composition
If the supporting structure is designed as an integrated unit, then structural stability is ensured, but the tillage implements cannot be detached for independent use
Solution Approach 1:
The supporting structure is divided into separable components: the support frame with bearing block and upper link forms one module, while the tillage implements are detachable attachments. This segmentation allows the implements to be removed and used independently while the support frame maintains its structural integrity
Solution Approach 2:
The support frame is designed as a universal platform that can function both as part of the complete spreading machine and as an independent support structure for various tillage implements. The upper link and bearing block configuration enables the frame to be used separately for soil cultivation tasks
3Weight of moving object
If vertical support elements are positioned below the bearing block, then the storage container is properly supported, but the structure becomes complex and blocks the view
Solution Approach 1:
The complex vertical support elements positioned below the bearing block are completely removed. The load-bearing function is achieved through the simpler configuration of support shoes at the underside and the upper link, reducing structural complexity while maintaining load capacity
Solution Approach 2:
Instead of supporting the storage container from below through vertical elements, the design inverts the support approach by using support shoes at the underside perimeter and an upper link above the bearing block. This inverted configuration simplifies the structure and improves visibility

AI summary
An agricultural spreading machine (1), in particular a seed drill, is proposed. It has a storage container (4) supported by a frame (6) for receiving spreading material, a metering device downstream of a discharge opening (8) of the storage container (4), and conveying means designed to convey the metered spreading material to a plurality of distribution devices (10). The frame (6) comprises, on the one hand, two support shoes (18) arranged on its underside and spaced laterally apart from each other, which are designed for attaching a first tillage implement (20), and, on the other hand, a bearing block (34) which is designed for mounting a top link (24) for detachably attaching the frame (6) to a second tillage implement (23) or to a tractor (3).The invention provides that each support shoe (18) is connected at its lower end to an outer support element (30), which extends upwards from the respective support shoe (18) and is inclined inwards at an angle between -10° and 60° with respect to a vertical plane (E1) arranged parallel to the direction of travel (F). Each outer support element (30) of a respective support shoe (18) is connected at its upper end, furthest from the respective support shoe (18), to the bearing block (34) by means of an inner support element (33), wherein the inner support element (33) extends inwards from the respective outer support element (30) and is inclined upwards at an angle greater than 0° and less than or equal to 90° with respect to a horizontal plane (E2) arranged at the level of the bearing block (34). Furthermore, the outer support elements (30) are connected to each other by means of a crossbeam (32) arranged above the level of the bearing block (34).
