Solution Overview

Problem

Baler pickup systems often plug with heavy or voluminous cut material, disrupting the baling operation and reducing efficiency.

Innovation Solution

A baffle float system with offset pivot axes and a compressor rack with flexible rods and springs, which automatically adjusts to accommodate varying crop conditions, preventing plugging by providing additional space and maintaining downforce on the crop material.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the pickup processes heavy and voluminous cut material, then the baling operation can handle large crop volumes, but the pickup plugs with material reducing efficiency

Engineering Contradiction:
Improvevolume of cut materialVSAvoidbaling operation efficiency
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The baffle float system employs a dynamic structure where the baffle is coupled to a float mechanism that automatically adjusts its position based on the volume and density of crop material. The float rises or falls with material accumulation, moving the baffle to maintain optimal spacing between the pickup and baffle, preventing plugging while handling varying crop volumes

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the spatial parameter (distance between pickup and baffle) dynamically based on material conditions. When heavy or voluminous material is detected through float position changes, the baffle automatically adjusts its location to increase clearance, preventing plugging incidents during high-volume processing

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the baffle is fixed in position, then the structure is simple, but it cannot accommodate varying crop conditions leading to plugging

Engineering Contradiction:
Improveaccommodation of varying crop conditionsVSAvoidbaffle float system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The float-controlled baffle system is self-regulating and requires no external control mechanisms. The float automatically responds to material volume changes, moving the baffle position in response to crop conditions without operator intervention or complex control systems, achieving adaptability with minimal added complexity

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The float mechanism serves multiple functions: it detects material volume, controls baffle position, and prevents plugging simultaneously. This multi-functional approach provides adaptability to varying crop conditions without requiring separate sensing and actuation systems

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A baffle float system (100) for a baler (10, 60) is disclosed. The baffle float system (100) comprises a pair of first pivot arms (114, 116) configured to pivotally couple to a frame (16) of the baler (10, 60) and to a cross-member (110), the first pivot arms (114, 116) pivot about a first pivot axis (P1); a baffle (106) coupled to the cross-member (110); a pair of second pivot arms (150, 152) having a first end (160) coupled to the cross-member (110) and a second end (172); a compressor rack (108) coupled to the second end (172) of each of the second pivot arms (150, 152) such that the compressor rack (108) pivots relative to the second end (172) along a second pivot axis (P2), the second pivot axis (P2) different than the first pivot axis (P1); and at least one biasing member coupled to the compressor rack (108) so as to be offset from the second pivot axis (P2), wherein an input force of the at least one biasing member results in a resultant force that acts on the compressor rack (108) and on the baffle (106).
