Spreading Machine Energy Supplier Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spreading machines, particularly precision seed drills, suffer from low energy efficiency and interfunctional dependencies among components due to the use of a single energy supplier, such as a blower or pump, which necessitates high power operation and results in inadequate energy utilization.
Innovation Solution
The implementation of at least two separate energy suppliers, such as blowers or pumps, to provide separation air flows to separating devices, conveying air to seed feeding devices, and energy to fertilizer supply devices, allowing for independent operation and power adjustment of each component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single energy supplier is used to operate all components (separating devices, seed feeding device, fertilizer supply device), then the device complexity is reduced, but the energy efficiency deteriorates and interfunctional dependencies increase
Solution Approach 1:
The patent divides the single energy supplier into multiple separate energy suppliers, each dedicated to specific components. The separating devices receive energy from one supplier, the seed feeding device from another, and the fertilizer supply device from a third supplier. This segmentation allows each energy supplier to be optimized for its specific function, eliminating the energy waste that occurs when a single supplier operates all components at high power with throttled output.
2Device complexity
If a single energy supplier operates all components, then the device complexity is reduced, but the controllability of individual components deteriorates
Solution Approach 1:
By segmenting the energy supply system into multiple independent suppliers, each component group (separating devices, seed feeding device, fertilizer supply device) can be controlled independently. This allows operators to adjust the power and operation of each component based on specific agricultural requirements without being constrained by the operational state of other components.
3Power
If the blower is operated at high power to satisfy all consumers, then the power availability is improved, but the energy efficiency deteriorates due to throttling of conveying streams
Solution Approach 1:
The patent segments the power delivery system so that each energy supplier provides power at the appropriate level for its specific consumers. The separating devices receive high power from their dedicated supplier, the seed feeding device receives appropriate power from its supplier, and the fertilizer supply device receives suitable power from its supplier. This eliminates the need to operate the blower at high power with throttled output, as each supplier operates at optimal power levels for its specific function.
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
This solution enhances energy efficiency by reducing unused energy and allows for improved controllability of energy distribution, reducing interfunctional dependencies and resulting in a more effective work process.
Implementation Method 1
In the case of a separating device operated under positive pressure, the separation air flow is acted on with positive pressure from a blower, so that the seed in separated form is pressed against a separation element
Implementation Method 2
in the case of a separating device operated under negative pressure, the separation air flow is acted on with negative pressure from a blower, so that it is suctioned from the separating device
Implementation Method 3
The seed feeding device conveys seed from the central, bulky seed hopper via piping, with the aid of the conveying air flow that is to be generated by a blower
Implementation Method 4
The fertilizer supply device is configured to convey, by means of a blower or a pump, granular or liquid fertilizer to fertilizer application devices of the spreading units

AI summary
A spreading machine, in particular a precision seed drill, includes at least one seed hopper, at least one fertilizer tank, and several spreading units. Each of the spreading units includes at least one pneumatically operated separating device, to or from which a separation air flow is suppliable or dischargeable, and a fertilizer application device. The spreading machine includes a conveying air-driven seed feeding device for providing seed from the seed hopper to the spreading units, and an energy-powered fertilizer supply device for providing fertilizer to the fertilizer application devices. To refine a spreading machine that includes a plurality of consumers, the spreading machine includes at least two separate energy suppliers, in particular blowers or pumps, for providing the separation air flows to the separating devices, the conveying air to the seed feeding device, and the energy to the fertilizer supply device.
