Deflector Shield Spring Mechanism Round Baler Gate Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Crop buildup above the axle and behind the pickup frame in round balers can prevent the bale discharge gate from closing, requiring frequent manual intervention by the operator, leading to reduced efficiency and productivity.
Innovation Solution
A deflector sheet attached to the baler above the axle and behind the pickup frame, with a spring member to deflect crop material away from the gate path, ensuring the gate can close without interference, and covers to prevent crop material from entering the deflector area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the gate is designed to pivot close after bale discharge, then the baling operation can continue efficiently, but crop buildup above the axle and behind the pickup frame may prevent the gate from closing properly
Solution Approach 1:
A deflector shield is introduced as an intermediary component between the crop buildup area and the gate closure path. The deflector intercepts and redirects crop material away from the gate, allowing the gate to close reliably without direct contact with obstructing vegetation. This mediator component resolves the contradiction by protecting the gate closure mechanism from harmful crop interference.
Solution Approach 2:
The deflector shield is positioned to preemptively intercept crop buildup before it can reach and obstruct the gate closure path. By performing the protective action in advance of potential interference, the system ensures reliable gate closure without requiring corrective interventions after crop material accumulates.
2Productivity
If the gate closes reliably without obstruction, then continuous baling operation is maintained, but crop material may accumulate in the area above the axle and behind the pickup frame interfering with gate closure
Solution Approach 1:
The deflector shield extracts or removes the harmful crop buildup from the gate closure path by intercepting it at an earlier location (above the axle and behind the pickup frame). By taking out the obstructing material before it can interfere with gate operation, the system maintains continuous productivity while eliminating the harmful effect of crop accumulation.
Solution Approach 2:
The deflector shield converts the potentially harmful crop buildup into a controlled flow pattern. Instead of allowing crop material to randomly accumulate and obstruct the gate, the deflector redirects it along a predetermined path that clears the gate closure area, transforming a harmful interference into a manageable material flow.
3Reliability
If manual cleaning is required to remove crop buildup, then the gate can close properly, but operator intervention is needed reducing efficiency and productivity
Solution Approach 1:
The deflector shield creates a self-service system where the gate closure mechanism itself helps clear crop buildup. As the gate pivots during normal operation, it automatically contacts and pushes crop material against the deflector, which redirects the material away from the closure path. This eliminates the need for separate manual cleaning operations while maintaining reliable gate function.
Solution Approach 2:
The system uses the dynamic motion of the gate during normal operation to perform the cleaning function. Rather than requiring static cleaning operations or additional active cleaning mechanisms, the deflector is positioned to be swept clear by the gate's natural pivoting motion, converting routine gate operation into an effective cleaning action that maintains both reliability and productivity.
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
Prevents crop buildup from interfering with gate closure, eliminating the need for operator intervention and maintaining baling efficiency by ensuring the gate can close without obstruction, allowing continuous operation.
Implementation Method 1
a deflector disposed proximal to the frame member, the deflector being disposed for contact with a portion of the gate when the gate closes so that the gate causes the deflector to deflect, thereby allowing the gate to close without interference from crop debris the deflector being biased toward a non-deflected position so that the deflector is returned to a non-deflected position when the gate is opened

AI summary
A shield is provided for preventing crop build-up above the axle and behind the pickup frame from interfering with the closure of the gate after bale discharge. A spring member is interposed between the baler frame and a deflector surface. Preferably the spring member occupies the entire space between the baler frame and the deflector thereby preventing any accumulation of crop material in that space. As the gate of the baler begins to close a gate shield of the baler contacts the deflector surface and compresses the spring member allowing the deflector surface to deflect toward the baler frame. Because crop material cannot build up in the area occupied by the spring member and deflector surface, deflection of the deflector surface provides a clean path for the gate shield allowing the gate to close without interference from crop material build-up. When the gate is opened again the spring member expands pushing the deflector surface and any accumulated crop material toward the center of the baler. A cover is also provided to prevent crop material from entering any space between the frame and the deflector surface and/or the spring member.
