Windrower Rake Comb and Blade Rotor for Homogeneous Forage Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing windrower rakes suffer from inconsistent and non-homogeneous forage flow, leading to material loss and entanglement issues, particularly in oblique reel rakes, which affect machine efficiency and performance.
Innovation Solution
A windrower rake design incorporating a comb with rotating disks and a blade rotor, where the blade rotor is positioned above and ahead of the comb, with a transverse shaft and sweeping elements that counteract the tangle direction, ensuring a constant and homogeneous forage flow by preventing dispersal and entanglement.

1Object-affected harmful factors
If oblique reel rakes are used to perform gentle raking, then forage is preserved without damage and cleaner forage is achieved, but forage flow becomes inconsistent and non-homogeneous causing material loss and entanglement
Solution Approach 1:
The rake is divided into two independent functional sections: a comb section with rotating bars for gentle raking and a blade rotor section with cutting blades for controlling forage flow. Each section performs its specific function independently, allowing the gentle raking action to be maintained while adding flow control capability to prevent material loss and entanglement.
Solution Approach 2:
The patent combines two different raking mechanisms (comb with rotating bars and blade rotor with cutting blades) into a single integrated windrower rake system. The comb section handles gentle raking while the blade rotor section manages forage flow consistency, creating a hybrid system that achieves both gentle handling and consistent flow.
2Device complexity
If traditional comb structure is used, then simple structure is maintained, but forage disperses and jumps over the comb causing entanglement in rotating parts
Solution Approach 1:
The blade rotor is designed to rotate independently from the comb structure, creating a dynamic system where the blade rotor can actively control forage flow. The rotating blades provide continuous motion to guide forage consistently, preventing dispersal and entanglement while maintaining operational flexibility through independent rotation.

AI summary
A windrower rake consisting of a comb and a rotor having a special configuration that makes it possible to optimise the windrowing system, avoiding material loss and forage entanglement in the rotating areas of the machine, thereby increasing the performance and efficiency of the machine. The comb contains a plurality of teeth arranged along several horizontal bars which, in turn, are mounted on either side on two rotating disks that rotate about a horizontal shaft. The blade rotor is located above and in front of the comb, including a transverse horizontal shaft to which a plurality of teeth, blades or disks distributed along the length thereof, are rigidly connected, partially covered by a casing.
