Continuous Square Baler Hay Feeding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing balers face issues with hay not being effectively compressed into the bale chamber, leading to ejection due to gravity or air force, and require complex mechanisms for adjusting timing with the flaker cart, resulting in inefficient operation and hay misplacement.
Innovation Solution
A quick feeding device with synchronized guides and gates ensures hay is placed above and below the semi-cylinder compression device, combined with a leaf stopper cutter and stuffer fingers to manage hay flow and storage, allowing for efficient compression and bale formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If stuffer fingers are used to lift hay into the leaf forming chamber, then hay can be moved into the chamber, but the operation speed slows down and effectiveness is reduced
Solution Approach 1:
The continuous hay stream is divided into discrete segments by the leaf stopper cutter, which cuts the hay into manageable sections that can be efficiently handled and placed into the bale chamber without slowing down the overall operation
Solution Approach 2:
The quick feeding device acts as an intermediary mechanism between the stuffer fingers and the bale chamber, rapidly transporting cut hay segments to the correct position above or below the semi-cylinder compression device, thereby maintaining high speed while ensuring effective placement
2Ease of operation
If hay is not cut into sections but merely pulled apart, then the feeding process is simpler, but hay is ejected into wrong places due to lack of definite segments
Solution Approach 1:
The leaf stopper cutter divides the continuous hay stream into definite segments, creating discrete sections that can be precisely controlled and placed into the bale chamber at the correct locations, eliminating the problem of hay being ejected into wrong places
Solution Approach 2:
The system dynamically adjusts hay placement by using the quick feeding device to position segments above or below the semi-cylinder based on the compression cycle phase, ensuring accurate placement while maintaining operational simplicity
3Device complexity
If there is no definite way of storing hay during bale tying, then the structure is simpler, but forward motion of the baler is delayed
Solution Approach 1:
Hay is pre-positioned above and below the semi-cylinder compression device during the tying operation, so that when the tying is complete, hay is already ready for immediate compression without requiring the baler to stop or slow down, maintaining continuous forward motion
Solution Approach 2:
The quick feeding device continues to operate during the tying process, continuously placing hay segments into position, ensuring that the useful action of hay feeding never stops even when bale tying is occurring, thereby maintaining baler productivity
4Device complexity
If rake fingers do not direct hay into the bale chamber, then the mechanism is simpler, but hay is ejected due to gravity or air force created by semi cylinder movement
Solution Approach 1:
The quick feeding device serves as an intermediary that actively directs hay segments into the bale chamber at the correct timing and position, counteracting the harmful effects of gravity and air force that would otherwise cause hay ejection, while adding minimal structural complexity
Solution Approach 2:
Hay segments are pre-positioned and secured in place above or below the semi-cylinder before compression begins, ensuring they remain in the chamber during the high-speed movement and tying operation, preventing ejection without requiring complex continuous guidance mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures consistent hay placement and compression, improving bale formation efficiency by guiding hay segments into the compression area and managing storage during the tying process, maintaining forward progress of the baler.
Implementation Method 1
The second section of the guide is returned to its original position by gravity in the upper hay guide and by springs in the bottom hay guide.
Implementation Method 2
The second section of the guide is returned to its original position by gravity in the upper hay guide and by springs in the bottom hay guide.

AI summary
A feeding mechanism for a crop baler having a quick feeding device including hay guides which can be deflected by a semi cylinder compression mechanism. The hay guides guide the hay into the bale chamber. A cutting device is provided to divide the continuously fed hay into segments of hay to be placed above and below the compression roller. The mechanism also includes a method of storing a segment of hay while the baler binds the bale in the bale chamber with twine. The mechanism stores hay at the precise time the baler binds the bale in the bale chamber and clears the storage area while the next bale is being made. The mechanism will slow the speed of the semi cylinder, quick feed, leaf stopper cutter, and knotter needle system when binding a bale to allow the baler to operate at a higher speed when not binding the bale.
