Pneumatic Distribution Machine Remote Cover Flap Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing pneumatic distribution machines are uncomfortable and prone to incorrect operation due to the need for manual pivoting of a cover flap to close the feed-through opening, which can lead to incorrect dosing during seed sowing if not properly positioned.
Innovation Solution
A remote control device with an operating mechanism is used to selectively pivot the cover flap into the closing position, allowing operators to easily manage the cover flap from the side, ensuring it is always in the correct position for seed sowing, and the collection container can only be pulled out when the cover flap is closed, preventing incorrect operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover flap is manually pivoted by the operator to close the feed-through opening, then the operator can access the central area of the machine, but the operator must bend towards the center or enter the machine which is very uncomfortable
Solution Approach 1:
A remote control device with operating means is introduced as an intermediary between the operator and the cover flap. The operating means is positioned in the outer area of the machine where the operator can easily reach it, while the cover flap remains in the central area. This mediator transmits the operator's control inputs to pivot the cover flap into the desired position without requiring the operator to physically access the central area.
Solution Approach 2:
The control system is segmented into two separate components: the operating means for the remote control device positioned in the outer area, and the cover flap in the central area. This segmentation allows the operator to control the cover flap from a comfortable position outside the central area, eliminating the need to bend or enter the machine.
2Ease of operation
If the collection container is pulled out by rope without pivoting the cover flap, then the container can be removed easily, but incorrect dosing occurs if the cover flap is not in the closing position
Solution Approach 1:
The system requires the cover flap to be pivoted into the closing position as a preliminary action before the collection container can be pulled out. The remote control device ensures this condition is met before allowing container removal, preventing incorrect dosing while maintaining easy container removal through the rope mechanism.
Solution Approach 2:
The system incorporates feedback through the remote control device that monitors the position of the cover flap. The device provides information about whether the cover flap is in the correct closing position, allowing the operator to verify the state before pulling out the collection container, thus ensuring correct dosing.
3Ease of operation
If the operating means is positioned in the outer area of the machine, then the operator can easily operate it from the side, but the control mechanism becomes more complex
Solution Approach 1:
A remote control device serves as an intermediary mechanism connecting the operating means in the outer area to the cover flap in the central area. This mediator transmits mechanical motion or control signals over the distance, allowing easy operation from the side while managing the complexity through a dedicated control system.
Solution Approach 2:
The patent allows for the remote control device to be designed using non-mechanical means such as electrical or electronic actuation elements. This substitution replaces complex mechanical linkages with simpler electrical systems, reducing overall device complexity while maintaining accessibility of the operating means in the outer area.

AI summary
Pneumatic distribution machine with a frame (1), funnel-shaped storage container (3), a metering device (5) arranged at the lower end (4) of the funnel-shaped storage container (3), a pneumatically actuated conveying line (6) leading to a distributor head with an injector (7) having at least one feed opening, wherein the material to be dispensed, located in the storage container (3), is fed from the metering device (5) into the conveying line (6) via the feed opening of the injector (7), wherein the injector (7) has in its wall opposite the feed opening a through-opening (9) for the material metered during the turning process, which can be covered by a cover flap (10) arranged to pivot about a horizontal axis, wherein a collection container (12) is to be arranged below the through-opening for carrying out (3) the turning process and for collecting the material metered during the turning process.The collection container (12) is positioned below the through-opening (9) via a sliding guide (13) arranged on the frame (1) for the purpose of carrying out the twisting process. To ensure in a simple manner that the cover flap must be forcibly pivoted into the position closing the through-opening after completion of the twisting process, a remote control device (18) with an operating means (17) is provided for the cover flap (10) for selectively pivoting the cover flap (10) into the respective covering position and/or twisting position.
