Harvester Bottom Floor Assembly Rotation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural balers often experience clogging in the crop feeding channel due to high-speed operation, leading to reduced harvesting efficiency, as the traditional design lacks effective mechanisms to manage the bottom floor assembly, which is crucial for preventing clogs.
Innovation Solution
A harvester control system that includes a bottom floor assembly with movable cutting knife units and sensors to detect their position, allowing operators to control the rotation of the bottom floor frame, providing warnings if certain rotational limits are exceeded, thus preventing clogs by increasing the channel volume temporarily.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the harvester operates at higher speeds to increase productivity, then the harvesting efficiency is improved, but the crop feeding channel becomes more prone to clogging
Solution Approach 1:
The bottom floor assembly is designed to move dynamically in response to crop material accumulation. When clogging is detected or anticipated during high-speed operation, the bottom floor automatically adjusts its position to restore proper material flow, allowing the harvester to maintain high productivity without sacrificing channel reliability
Solution Approach 2:
The system incorporates sensors that continuously monitor the crop feeding channel for signs of clogging. This feedback mechanism triggers automatic adjustment of the bottom floor assembly or alerts the operator, enabling preventive action before clogging stops the harvesting operation
2Reliability
If the bottom floor assembly is allowed to move to increase channel volume and prevent clogs, then the crop feeding reliability is improved, but the device complexity increases
Solution Approach 1:
The bottom floor assembly is equipped with sensors and actuators that enable it to detect clogging conditions and adjust its own position automatically. This self-service capability reduces the need for complex external control systems and manual intervention, managing the added complexity through automation
Solution Approach 2:
The movable bottom floor assembly serves multiple functions: it supports crop material during normal operation, automatically adjusts to prevent clogging, and can be controlled manually when needed. This multi-functionality justifies the added complexity by providing versatile solutions to various operational challenges
3Productivity
If the bottom floor assembly moves to increase channel volume, then the productivity is improved by preventing clogs, but the control difficulty increases
Solution Approach 1:
Sensors continuously monitor the crop feeding channel and provide feedback to the control system. This automatic feedback loop manages the complexity of controlling a movable bottom floor, allowing productivity improvement while maintaining ease of operation through automation
Solution Approach 2:
The bottom floor assembly automatically detects and responds to clogging conditions without requiring constant operator intervention. This self-service capability simplifies operation while maintaining high productivity by preventing clogs before they stop the harvester

AI summary
The disclosure relates to a harvester control system that allows for the operation and control of a bottom floor assembly (220) by an operator of a harvester (10), such as a round baler. The harvester control system generally comprises at least one rotation sensor (240) configured to measure the rotation angle of the bottom floor assembly (220) during the harvesting process, a controller that receives information from the rotation sensor(s), and an operator interface configured to display warning information to the operator if the bottom floor assembly (220) meets certain rotation and time parameters.
