Pivotable Discharge Frame for Manure Spreader Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for distributing spreadable materials like manure and compost face challenges in accessibility and maintenance due to the high weight of the discharge device, making it difficult to replace wearing parts such as knives and conveyor elements.
Innovation Solution
A discharge device frame is designed to pivot about a vertical axis on the side wall of the trough, allowing separation from the trough and connection via a hinge flange system for improved accessibility, enabling easy maintenance both on and off the chassis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the discharge device is made heavy and robust for stable operation, then the reliability of material conveyance is improved, but the accessibility for maintenance and replacement of wearing parts deteriorates
Solution Approach 1:
The discharge device is divided into separate components: the frame carrying the discharge device can be separated from the trough by an axis of rotation, allowing the discharge device to be detached for maintenance while keeping the heavy robust construction for reliable operation during use
Solution Approach 2:
The frame is designed to be pivotable about a vertical axis of rotation in the side wall area of the trough, enabling dynamic repositioning and separation of the discharge device from the trough for improved accessibility during maintenance operations
2Reliability
If the discharge device is fixed permanently to the trough for stable operation, then the reliability of material conveyance is improved, but the ease of maintenance and part replacement deteriorates
Solution Approach 1:
The discharge device is segmented from the trough through the pivotable frame connection, allowing permanent stable operation during use while enabling easy separation for maintenance of wearing parts such as knives and conveyor elements
Solution Approach 2:
The discharge device can be extracted from the trough assembly by pivoting the frame about the vertical axis, allowing maintenance personnel to access and replace wearing parts without removing the entire discharge device from the vehicle

AI summary
The device (1) has a conveying device (5) pushing against a discharge device that is laterally moved from a tub (2). The discharge device comprises a circumferentially driven crushing device (18) that is turned towards loaded goods for treatment of spreading goods. The discharge device has an ejection device (19), which is arranged downstream to the crushing device and works transverse to a traveling direction. A base frame (9) supports the discharge device and is separable by a swiveling or an extension movement from the tub. The frame is designed as a housing (10) of the discharge device.
