Reversible Plough Centralized Locking Control for Transport Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reversible plows face a significant risk of accidents due to the complexity and potential for error in securing the transport position, particularly in ensuring the correct order and engagement of locking mechanisms during configuration changes from working to transport mode.
Innovation Solution
A centralized control device is introduced to manage the engagement and disengagement of locking mechanisms, defining a specific order of operations to guarantee secure transition between working and transport configurations, preventing involuntary rotation during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operator manually secures the transport position using multiple locking mechanisms, then the plough can be transported, but the risk of accidents increases due to potential errors in operation sequence
Solution Approach 1:
The patent combines multiple locking mechanisms (first locking means for the bracket and second locking means for the pivot connection) under a single centralized control device. This merging allows the operator to secure both locking mechanisms simultaneously through one operation, eliminating the need to manually manage multiple locks separately and reducing the risk of operational errors.
Solution Approach 2:
The centralized control device is designed to automatically execute the correct sequence of locking operations before the plough is transported. The device performs preliminary actions by automatically engaging the first locking means and then the second locking means in the proper sequence, ensuring safety conditions are met before transport without requiring the operator to remember or execute a complex sequence.
2Adaptability or versatility
If the upper connecting rod is uncoupled during transport, then the plough can be pulled behind the tractor, but the risk of accidents increases if the turning device is not properly locked
Solution Approach 1:
The centralized control device merges the control of the upper connecting rod uncoupling mechanism with the control of the turning locking mechanism. When the operator activates the control device for transport mode, it simultaneously uncouples the upper connecting rod and engages the second locking means to secure the turning device, ensuring both actions occur together and eliminating the risk of one action being performed without the other.
Solution Approach 2:
The centralized control device provides feedback to the operator about the status of both the upper connecting rod and the turning locking mechanism. The device monitors whether both operations have been successfully completed and only allows transport mode to be activated when both conditions are met, preventing accidental transport with improper securing.
3Reliability
If the operator must perform multiple sequential operations to secure the plough, then all components can be properly locked, but the time and effort required increases
Solution Approach 1:
The centralized control device merges multiple sequential locking operations into a single integrated control action. When the operator activates the device, it simultaneously initiates and coordinates the engagement of both locking means, reducing the time required to secure the plough while ensuring both locking operations are completed reliably.
Solution Approach 2:
The control device performs preliminary actions by automatically executing the complete sequence of locking operations in the correct order before the operator needs to transport the plough. This eliminates the need for the operator to spend time manually performing each locking step while ensuring all necessary locking actions are completed.

AI summary
The present invention relates to a reversible plow comprising, on the one hand, a frame (2) carrying plow bodies and equipped with at least one wheel and, on the other hand, a hitch head (16) with a boom (4) and a three-point hitching device (5, 5', 5") for coupling it with a tractor vehicle, said plow being able to be transposed by rotation around a turning axis (AR) between the different configurations, the upper hitching point (5) being movable relative to the boom (4) in transport configuration, and said plow also comprising a first means (9) for locking the upper hitching point (5) in position and a second means for locking the pivot joint (6) in rotation, and therefore the rotation of the frame (2).Plough characterized in that it further comprises a common control device (11) for the engaged/disengaged state of said first and second locking means, this device (11) being configured so as to define an order of succession of the actuation or release operations.
