Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural machines lack the ability to independently and flexibly determine the placement of windrows and the direction of harvested products, limiting operational versatility and efficiency.
Innovation Solution
An agricultural machine with a frame, two harvesting devices aligned transversely to the movement direction, and unloading equipment featuring a central unloading device movable between operational and non-operational positions, allowing products to be directed to various unloading zones without interference from the wheels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the central unloading device is fixed in position, then the structure is simple and reliable, but the operational versatility and flexibility are limited
Solution Approach 1:
The central unloading device is made movable relative to the harvesting devices, allowing it to be positioned in different locations (including behind the wheels). This dynamic repositioning capability enables the system to adapt to various operational requirements and windrow placement configurations, directly resolving the contradiction between operational versatility and device complexity.
2Adaptability or versatility
If the unloading equipment is positioned fixedly, then the device complexity is low, but the ability to direct harvested products to various zones is limited
Solution Approach 1:
The unloading equipment is segmented into multiple independent components: a central unloading device and lateral unloading devices, each capable of independent movement and positioning. This segmentation allows each component to be optimized for specific functions while collectively providing versatile product direction capabilities without excessive overall complexity.
Solution Approach 2:
The central unloading device can move to different positions including behind the wheels, enabling flexible product direction. This dynamic capability allows the system to direct harvested products to various zones depending on operational needs, resolving the contradiction between product direction flexibility and device complexity.
3Object-affected harmful factors
If the central unloading device is positioned behind the wheels, then product damage is prevented, but the unloading capacity may be reduced
Solution Approach 1:
The central unloading device can dynamically reposition itself to locations behind the wheels when needed to prevent product damage from wheel contact. This dynamic positioning allows the system to avoid harmful effects on products while maintaining operational effectiveness, resolving the contradiction between product protection and unloading capacity.
4Adaptability or versatility
If the harvesting devices are arranged in fixed positions, then the device complexity is low, but the ability to arrange windrows in various configurations is limited
Solution Approach 1:
The harvesting devices are made movable relative to the frame, allowing them to be repositioned to different locations and orientations. This dynamic adjustment capability enables the system to arrange windrows in various configurations according to operational requirements, directly resolving the contradiction between windrow arrangement flexibility and device complexity.

AI summary
An agricultural machine, includes a frame with a pair of wheels enabling movement in one direction, at least two harvesting devices for agricultural products connected to the frame that, in a work position, are arranged frontally to the wheels and aligned with each other transversely to the one direction. Unloading equipment is arranged operationally downstream of the harvesting devices to receive the harvested agricultural products and to move them in an unloading direction transverse to the one direction. The unloading equipment includes a central unloading device that is movable with respect to the harvesting devices between a work position, wherein it directly receives the harvested agricultural products from the harvesting devices, and a non-operational position, wherein offset with respect to the work position so as to enable the harvested agricultural products to fall immediately downstream of the first harvesting device.
