Solution Overview

Problem

Existing agricultural baler systems face inefficiencies due to irregular material influx into the pre-compression chamber, leading to overfeeding or underfeeding, especially with conveyor-based systems, which results in mechanical complexity and production speed challenges.

Innovation Solution

A buffer chamber with a conveyor belt floor, synchronized with the pre-compression chamber's conveyor belts, ensures a constant crop supply by smoothing fluctuations and using closing mechanisms at inlet and outlet sections to control material flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conveyor-based systems are used to advance crops towards the baling chamber, then productivity is improved, but device complexity increases and reliability decreases due to mechanical problems at high speeds

Engineering Contradiction:

Improveproduction speedVSAvoidmechanical complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The invention extracts the problematic mechanical conveyor system from the pre-compression chamber and replaces it with a buffer chamber that uses gravity and controlled opening/closing mechanisms. This removes the complex rotating forks and continuous conveyor belts that caused reliability issues at high speeds, while maintaining productivity through the buffer chamber's regulated material release.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The buffer chamber acts as an intermediary between the crop supply system and the pre-compression chamber. It receives irregular crop influx, stores it temporarily, and releases it at a controlled rate through opening/closing mechanisms, thereby decoupling the high-speed baling operation from the irregular crop supply and eliminating the need for complex mechanical conveyors in the pre-compression chamber.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If conveyor belts continuously move to advance material, then productivity is improved, but harmful factors increase due to premature material entry and material trapping

Engineering Contradiction:

Improvefilling efficiencyVSAvoidmaterial trapping and premature entry

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The invention replaces continuous conveyor belt movement with periodic opening and closing of the buffer chamber inlet/outlet sections. Material is released in controlled periodic cycles rather than continuously, which prevents premature entry into the pre-compression chamber and eliminates material trapping between conveyor rolls, while still maintaining high filling efficiency.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The buffer chamber performs preliminary storage and conditioning of crop material before it enters the pre-compression chamber. By pre-storing material in a controlled environment and regulating its release timing, the system ensures material is ready for efficient pre-compression without the harmful effects of continuous conveyor movement, such as trapping and premature entry.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If pre-compression chamber is equipped with rotating fork arrangements, then material can be stuffed into baling chamber, but device complexity increases making operation difficult at high speeds

Engineering Contradiction:

Improvematerial stuffing capabilityVSAvoidrotating mechanism complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The invention removes the complex rotating fork arrangement from the pre-compression chamber and replaces it with a simplified opening/closing mechanism at the buffer chamber outlet. Material is pushed into the pre-compression chamber by the buffer chamber's closing action rather than by rotating forks, eliminating the complex rotating mechanism while maintaining effective material stuffing capability at high speeds.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention replaces the mechanical rotating fork system with a simpler opening/closing mechanism driven by the buffer chamber's controlled access system. This substitution eliminates complex rotating parts, reduces mechanical complexity, and improves ease of operation at high production speeds while maintaining the ability to effectively stuff material into the baling chamber.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An agricultural baler equipped with a pre-compression chamber supplied with crop material by a suitable supply or arrangement or component, and configured to guide crop material from the supply towards and into the baling chamber where the rectangular bales are formed. The baler of the invention is provided with a buffer chamber located before the pre-compression chamber, the floor of said buffer chamber being formed by a conveyor belt configured to move at a constant speed. The buffer chamber diminishes the irregularity with which crops are supplied to the pre-compression chamber.
