Semi-Mounted Turn-About Plough With Independent Offset Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing semi-mounted reversible ploughs require complex and time-consuming adjustments between furrow and on-land working positions, with limited adjustment ranges due to the interdependence of actuators, making them difficult to operate efficiently.
Innovation Solution
The semi-mounted reversible plough incorporates two independent actuators - an offset actuator and an adjustment actuator - allowing for independent adjustment of the offset arm and front furrow arm, expanding the adjustment range and enabling remote control for easier transitions between working positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single adjustment actuator is used to control the offset arm and front furrow arm, then the structure is simpler, but the adjustment range is limited and the operation becomes complex and time-consuming
Solution Approach 1:
The single adjustment actuator is divided into two independent actuators: an offset actuator for controlling the offset arm and an adjustment actuator for controlling the front furrow arm. This segmentation allows each actuator to independently adjust its respective arm, thereby expanding the overall adjustment range without requiring complex repositioning operations.
Solution Approach 2:
The system transitions from a static, single-point adjustment mechanism to a dynamic, multi-point adjustment system. The two independent actuators can operate simultaneously or separately, allowing continuous and flexible adjustment of the plough's position and orientation, enhancing adaptability to different working conditions.
2Adaptability or versatility
If the adjustment actuator position is changed or arms are manually locked to achieve different lateral distances, then the adjustment range is extended, but the operation becomes complex and time-consuming
Solution Approach 1:
The offset actuator is pre-configured to control the offset arm, and the adjustment actuator is pre-configured to control the front furrow arm. This preliminary arrangement of control functions allows operators to directly adjust to desired positions without needing to manually reposition actuators or lock arms, significantly reducing adjustment time.
Solution Approach 2:
The system enables self-adjustment through independent actuator control. Each actuator automatically controls its associated arm to the desired position based on operational requirements, eliminating the need for manual intervention to reposition actuators or lock mechanisms, thereby reducing time loss during adjustments.
3Ease of operation
If two independent actuators are used to control offset arm and front furrow arm, then the adjustment range is extended and operation is simplified, but the device complexity increases
Solution Approach 1:
Both actuators are designed with universal mounting interfaces and control systems that can be integrated into existing plough frameworks. The offset actuator and adjustment actuator share common control electronics and hydraulic/pneumatic systems, allowing them to function as a unified multi-functional adjustment system rather than separate complex subsystems.

AI summary
The invention relates to a semimounted turn-about plough (1) comprising: an attachment member (2) for attachment to a tractor; a stabiliser (3) which is connected to the attachment member (2) and on which a plough frame (6) carrying two rows of plough shares (5) is mounted rotatably about a horizontal turning axis by means of at least one turning arm (7V), in particular a front turning arm, an offset rocker (9), which is rotatably connected to the turning arm (7V), and a front furrow rocker (10), which is connected to the offset rocker (9) in an articulated manner on one side and connected rotatably to the plough frame (6) on the other side, being arranged between the plough frame (6) and the turning arm (7V), which rockers can be brought by means of an adjustment actuator (11) into positions effecting different transverse distances (12, 120, 12F) between the attachment member (2) and the frontmost plough share (5V) in the direction of travel (F), such that the semimounted turn-about plough (1) is configured to assume either a furrow working position or an onland working position. To create an improved semimounted turn-about plough (1), according to the invention the semimounted turn-about plough (1) comprises an offset actuator (14) by means of which the offset rocker (9) and the front furrow rocker (10) can be brought into positions effecting different transverse distances (12, 120, 12F) between the attachment member (2) and the frontmost plough share (5V) in the direction of travel (F), independently of the lift position of the adjustment actuator (11).
