Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for applying fertilizers like manure on agricultural areas face challenges in adapting to varying ground contours, leading to uneven application and potential fertilizer loss or equipment damage, especially with large working widths.
Innovation Solution
A device with a rear frame holder, support frame, and adjustable side arms with towing hose booms, allowing for rotation around multiple axes to maintain optimal outlet positioning relative to the ground contour, ensuring even fertilizer distribution and preventing equipment damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If outlets are positioned close to the ground for precise application, then application precision is improved, but outlets may drag on the ground causing damage
Solution Approach 1:
The side arm is designed to be adjustable between operating position and transport position, allowing dynamic adaptation to different ground contours. This enables the outlet to maintain optimal distance from the ground during operation while preventing ground contact during transport, resolving the contradiction between application precision and equipment durability
2Reliability
If outlets are positioned far from the ground to prevent damage, then equipment durability is improved, but application precision deteriorates
Solution Approach 1:
The adjustable side arm mechanism allows the outlet to be positioned close to the ground during operation for precise application, then moved to a higher position during transport to prevent damage. This dynamic repositioning resolves the contradiction by optimizing both positions at different operational stages
3Productivity
If large working width is used to reduce number of passes, then productivity is improved, but adaptability to ground contours deteriorates
Solution Approach 1:
The device divides the working width into multiple segments with individual adjustable side arms, each capable of independent adaptation to ground contours. This segmentation allows large working width for high productivity while maintaining adaptability through localized adjustment of each segment to varying ground conditions
Solution Approach 2:
Each side arm can be independently adjusted to match local ground contour characteristics, allowing different parts of the large working width to adapt to their specific terrain conditions. This local quality approach maintains ground contour adaptability across the entire wide working area
4Device complexity
If fixed outlet position is used for simple structure, then device complexity is reduced, but adaptability to varying ground contours deteriorates
Solution Approach 1:
The side arm is designed with adjustable positioning capability between operating and transport positions, providing adaptability to varying ground contours while maintaining relatively simple structural implementation through rotational joints and positioning mechanisms

AI summary
The invention relates to a device for applying a pumpable medium, in particular a fertiliser such as slurry, to a strip of agricultural land, comprising: a rear frame holder (11) having a rear frame holder interface for securing to a rear frame (91) of a container, in particular a slurry container; a support frame (10) which is mounted on the rear frame holder (11) such that it can rotate about a first axis of rotation (100) extending in a transverse direction; a first boom (20) which extends in the transverse direction in an operating position, is connected to the support frame (10) and is mounted on the support frame (10) such that it can rotate about a second axis of rotation (200); a first side arm (25) secured to the first boom (20), which extends in a side arm longitudinal direction and on which multiple drag hose booms are arranged along the first side arm (25), spaced apart from one another in the side arm longitudinal direction and having a respective outlet opening at the ends; wherein the first side arm (25) can be adjusted between the operating position in which the first side arm (25) extends in the transverse direction and the drag hose booms extend downwards from the first side arm (25), and a transport position in which the first side arm (25) extends in a longitudinal direction lying transverse to the transverse direction and the drag hose booms extend upwards from the first side arm (25), wherein the first and the second axes of rotation (200) are arranged such that the adjusting between the operating position and the transport position occurs via a rotation of the support frame (10) about the first axis of rotation (100) by a first angle and a rotation of the first boom (20) about the second axis of rotation (200) by a second angle.
