Front-Mounted Transfer Assembly for Liquid Manure Pumping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural vehicles lack an efficient system for pumping and distributing liquid manure across fields, requiring separate vehicles and high horsepower for pumping, and existing methods for evacuating liquid manure from hoses are inefficient.
Innovation Solution
A transfer assembly removably attached to the front of an agricultural vehicle, equipped with a frame, fluid pump, air compressor, and pulley system, allowing for efficient pumping and distribution of liquid manure, and using pressurized air to evacuate the hose.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a pump is mounted onto the front portion of an agricultural vehicle to move liquid manure through a flexible hose, then the pumping efficiency and mobility are improved, but the device complexity and horsepower requirements increase
Solution Approach 1:
The patent combines the pump, air compressor, and hose evacuation system into a single integrated transfer assembly that mounts to the front portion of the agricultural vehicle. This merging of previously separate functions (pumping and hose evacuation) into one unified device reduces overall system complexity while maintaining high pumping efficiency. The assembly includes a pump for moving liquid manure and an air compressor connected to a hose for evacuation, all mounted together on a common frame structure.
Solution Approach 2:
The transfer assembly serves multiple functions: it acts as a pump mounting structure, an air compressor mounting structure, and a hose evacuation system. The assembly can be removably attached to the front portion of the vehicle, providing universal applicability for both pumping operations and hose clearance operations. This multi-functionality eliminates the need for separate vehicles or equipment for each task.
2Adaptability or versatility
If separate vehicles are used for pumping and foraging operations, then operational versatility is maintained, but productivity and efficiency are reduced
Solution Approach 1:
The transfer assembly enables a single agricultural vehicle to perform multiple functions by providing both pump mounting capabilities and air compressor mounting capabilities. The assembly can be attached to the front portion of the vehicle for pumping operations, and the same vehicle can subsequently perform foraging operations by removing the assembly and attaching a foraging head. This eliminates the need for separate dedicated vehicles for each function, thereby improving productivity while maintaining operational versatility.
3Device complexity
If manual hose evacuation methods are used, then equipment cost is reduced, but time consumption and labor requirements increase
Solution Approach 1:
The patent employs pneumatic principles by using an air compressor to deliver pressurized air through a hose for evacuating liquid manure from the flexible hose. The pressurized air forces a ball through the hose, which in turn pushes any remaining liquid manure out through the spray nozzles. This pneumatic evacuation method is significantly faster and more efficient than manual methods, reducing time consumption while the entire system remains mounted on the vehicle for easy deployment.
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
Enables efficient pumping and distribution of liquid manure across fields using the vehicle's horsepower, reducing the need for separate equipment and improving hose evacuation efficiency.
Implementation Method 1
The air compressor can be used to deliver pressurized air which can force the ball to move through the flexible hose and push any liquid manure that is in front of it out through the spray nozzles
Implementation Method 2
The pump can then be operated to pump the liquid manure through the flexible hose to the spray nozzles where it is deposited onto the field

AI summary
A transfer assembly for attachment to a front portion of an agricultural vehicle, i.e. forage harvester, and a method of use are disclosed. The transfer assembly includes a frame, a pump and an air compressor, along with appropriate drive mechanisms. The agricultural vehicle has an engine and drive mechanisms including a first driven pulley. The pump is connected to the first driven pulley through second and third driven pulleys. The pump is secured to the frame and has a fluid inlet and a fluid outlet. A transfer pipe routes the fluid or manure away from the pump and has a coupling connected to its second end. The coupling enables a flexible hose to be attached to it so that the fluid or manure can be directed to another location, such as onto a field. The transfer assembly also includes a control mechanism for operating the pump, air compressor, etc.
