Continuous Round Baler Bale Severance Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional round balers require operational interruptions to eject formed bales, leading to inefficiencies, increased complexity, and crop loss, as they lack continuous operation capabilities like rectangular balers.
Innovation Solution
A continuous round baler design featuring a conical portion for initial crop material accumulation and a cylindrical portion for bale formation, allowing continuous operation without the need for a second chamber, with a net wrapping system that applies netting material during bale formation, and a cutoff mechanism for controlled bale length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional round balers use a single chamber design, then the structure is simpler, but operational interruptions are required to eject formed bales
Solution Approach 1:
The bale chamber is divided into a conical portion and a cylindrical portion, allowing the conical section to accumulate crop material while the cylindrical section forms and ejects bales. This segmentation enables continuous operation without requiring a second chamber, resolving the contradiction between structural simplicity and continuous productivity.
2Ease of operation
If conventional round balers stop to eject bales, then bale ejection is controlled, but operational time is lost
Solution Approach 1:
The bale severance mechanism operates continuously during bale formation and ejection without requiring operational stops. The conical portion continuously feeds crop material to the cylindrical portion, enabling uninterrupted bale production and eliminating time losses associated with stopping and starting the baling process.
3Reliability
If conventional round balers use heavy needle mechanisms for wrapping, then bale securing is effective, but device complexity and weight increase
Solution Approach 1:
The patent replaces heavy needle mechanisms with a net wrapping system that applies netting material around the cylindrical bale during formation. This substitution maintains effective bale securing while significantly reducing mechanism complexity and weight, as the netting is applied continuously without requiring complex positioning and knotting systems.
4Stability of the object's composition
If conventional round balers use large components for bale handling, then bale stability is maintained, but component weight and complexity increase
Solution Approach 1:
The patent changes the geometric parameters of the bale chamber from traditional cylindrical designs to a conical-cylindrical combination. The conical portion with its tapered geometry provides effective crop material accumulation and bale formation with lighter components, while the cylindrical portion maintains bale stability during ejection. This parameter change allows lighter components to achieve the same functional performance.

AI summary
A continuous round baler forms a cylindrically-shaped bale by spiral, coiled layers created by a conical portion of a bale-forming chamber and protruded upwardly from a cylindrical portion of the bale-forming chamber. The bale is circumferentially supported by netting applied to the bale in the cylindrical portion. A rotary feed table receives crop from the field and feeds the crop into the conical portion. The bale forming process can be interrupted if an insufficient volume of crop is collected on the rotary feed table. The netting material is provided on short rolls to facilitate loading onto the machine. A cutoff mechanism is coupled to the growth of the bale from the cylindrical portion to sever the bale at a predetermined length with end surfaces that are perpendicular to the axis of the bale. A bale density mechanism supports the distal end of the bale as the bale protrudes upwardly.
