Manure Slide Rotational Joint for Floor Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manure removal devices often fail to maintain effective contact with the floor, leading to inefficient removal of manure and other materials, particularly due to lifting moments caused by horizontal forces during operation.
Innovation Solution
A device with a manure slide held by a connection structure featuring a first rotational center line below the upper edge of the manure-pushing wall, allowing for low rotation and reduced lifting moments, combined with a second rotational center line at a 90-degree angle for improved directional adjustment, and optionally incorporating a floor-treating member like a brush for enhanced stability and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the manure slide is connected with a high rotational center line, then the adjustment to local floor changes is improved, but the lifting moment increases causing loss of contact with the floor
Solution Approach 1:
The patent introduces a second rotational degree of freedom perpendicular to the first rotational center line. This allows the manure slide to adjust to local floor changes in one dimension while the low rotational center line minimizes lifting moments in the vertical dimension, effectively resolving the contradiction by operating in multiple dimensional spaces simultaneously.
Solution Approach 2:
The patent changes the critical parameter of rotational center line height from high to low position. By locating the first rotational center line below the upper edge of the manure-pushing wall portion, the moment arm is reduced, thereby minimizing the lifting moment while maintaining adaptability through the rotational capability.
2Productivity
If the manure slide is made rigid to maintain contact with the floor, then the removal efficiency is improved, but the ability to adapt to local floor profile changes is reduced
Solution Approach 1:
The patent transforms the rigid manure slide into a dynamic structure with two rotational degrees of freedom. The connection structure allows the slide to rotate and pivot in response to local floor profile changes, maintaining effective contact and removal efficiency while adapting to varying floor conditions throughout operation.
3Adaptability or versatility
If the rotational center line is positioned far from the manure slide, then the rotational adjustment range is increased, but the moment arm increases causing greater lifting moments
Solution Approach 1:
The patent optimizes the position parameter of the rotational center line by locating it below the upper edge of the manure-pushing wall portion. This positioning achieves an optimal balance where sufficient rotational adjustment range is maintained while the moment arm is minimized, thereby reducing lifting moments without sacrificing adaptability.
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
The solution ensures effective contact with the floor, improving the removal efficiency of manure and other materials by minimizing lifting moments and enhancing stability, while allowing for adjustments to local floor changes and surface profiles.
Implementation Method 1
a low point of rotation is obtained, as a result of which the vertical moment arm of horizontal forces exerted on the manure slide, such as by the contact between floor and slide, is kept limited, and therewith a possibly occurring moment tending to lifting of the slide
Implementation Method 2
the connection structure can comprise a second rotational connection with a second, substantially horizontal rotational centre line which is at an angle, of preferably approximately 90 degrees, to the first rotational centre line

AI summary
A device (101) for removing material, such as manure, present on a floor (30)comprises a frame, a drive for moving the device over the floor and a first and a second floor-treating member. The two floor-treating members (104, 105) extend substantially over the width of the device and are mounted on a holder (121a, b). The holder is held by the frame by means of a connection structure. The first and the second floor-treating member are located in longitudinal direction at a distance from each other. The connection structure comprises a first rotational connection with a first, substantially horizontal rotational centre line, about which the holder with the two floor-treating members is rotatable with respect to the frame, while changing the orientation of the holder in a vertical longitudinal plane of the device. The first rotational centre line is substantially transverse to said longitudinal plane.
