Liquid Manure Distributor Arm Folding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid manure spreaders require complex adjusting mechanisms to pivot and secure spreader arms, making it difficult to achieve a large processing width while ensuring easy folding and secure transport.
Innovation Solution
A liquid manure spreader with a central distributor arm and lateral arms that can be pivoted and adjusted in height using a transversely movable axis within an elongated hole, combined with hydraulic cylinders for easy pivoting and height adjustment, and receiving devices for secure holding during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex adjusting mechanism is used to pivot and secure distribution arms, then the spreader arms can be securely held in position, but the device complexity increases
Solution Approach 1:
The patent extracts the securing function from a complex adjusting mechanism by using simple receiving devices with holding elements that passively secure the spreader arms in position. The transverse axis is guided in an elongated hole, allowing movement without requiring complex active control systems.
Solution Approach 2:
The spreader arms self-secure in the receiving devices through their own weight and geometry. The lateral distributor arms rest on the receiving devices with holding elements that automatically engage when the arms are in the transport position, eliminating the need for complex active securing mechanisms.
2Length of moving object
If the spreader arms are made foldable to reduce width, then transportation compliance is improved, but the ease of operation decreases
Solution Approach 1:
The patent implements dynamic positioning of the spreader arms through a simple transverse axis guided in an elongated hole, allowing the arms to move between transport and working positions. The receiving devices provide passive guidance and securing, making the dynamic operation simple and intuitive.
Solution Approach 2:
The spreader system is segmented into a central distributor arm and lateral distributor arms that can independently pivot and fold. Each arm can be operated separately, allowing flexible configuration for transport and working positions without requiring complex coordinated control.
3Device complexity
If the transverse axis is fixed in position, then the structure is simpler, but the adaptability to different positions is reduced
Solution Approach 1:
The transverse axis is made dynamically positionable within an elongated hole that extends vertically. This allows the axis to move between lower and upper positions, enabling adjustment of the distribution area width while maintaining a simple guided structure rather than a completely fixed or complex adjustable mechanism.

AI summary
The invention relates to a liquid manure distributor (10) comprising a liquid manure distributor system (16) having a central distributor arm (18) and two lateral distributor arms (20, 22) pivotally arranged thereon, which can be pivoted between a position aligned with the central distributor arm (18) and a position perpendicular to the central distributor arm (18), wherein the central distributor arm (18) can be pivoted about at least one transverse axis (34) between a folded down working position and a folded up transport position, wherein the at least one transverse axis (34) is guided to move translationally between a lower position and an upper position in at least one elongated hole (36) extending in the vertical direction of the liquid manure distributor (10).
