Automatic cutting line / rope length is controlled by magnetic principle, allowing for increased length. It relates to the scythe head. State of the Art Today, motorized trimmers are widely used in the agricultural sector. It is especially preferred for mowing weeds, grass, etc. Scythe heads. The function is usually performed manually. Agricultural workers use 15 scythe heads. By working behind the scenes, they visually monitor the length of the line (cutting line), noticing if it shortens. In this situation, the extension is achieved by tapping the cap on the ground, and manual adjustments are made as needed. This process ensures that operators constantly focus on the scythe head and This requires manual intervention. This method draws the operators' attention. It can disrupt and reduce work efficiency. Another significant problem is replacing the cutting process with 20 a robot that can walk, wheel, or track (like a tractor, motorbike, wheelbarrow, etc.) and deliver Or it can be described as the inability to use existing products by a mobile system.

If necessary, the magnetic material (14) is placed on the upper part of the inner coil (6) (13) It is located and provides configuration according to the magnetic flux path requirement. 10 Permanent magnets with different pole arrangements depending on the need (15), magnetic material (14) spring (5) on the inner roller (6) when the electromagnet windings (4) are triggered turning the inner pulley (6) by creating an opposing force in the direction of pushing or pulling against the force. by releasing the rotating pulley teeth (11) that prevent it from falling and 15 By providing limited rotation of the inner roller (6) with centrifugal force, the fishing line (10) The fishing line automatically extends outwards from the outlet adapter (8). The electromagnet coils (4) are activated by the control unit (3) and remain permanently. It enables a force to be applied to the magnets (15) in the direction of repulsion or attraction. 20 The working principle of the structure that is the subject of the invention is as follows: It has the shape of a traditional scythe head (7) and is driven by a gasoline or electric motor. The drive shaft (1) rotates the head according to the gas power. The 25 wound on the inner roller (6) The fishing line (10) comes out through the fishing line outlet adapter (8). In general, it comes out The dangling line (10) is expected to have a length of around 20 cm. At a certain length Scythe heads (7) that can hold the fishing line are opened with the scythe head opening tab (9) and put into the inner reel (6) Manual winding can be performed or by using the line winding adapter (12). The wrapping process can be done from the outside. 30 The inner roller (6), spring (5) mechanism, electromagnet windings (4), control unit (3) and It is freed by magnets (15) and rotates due to centrifugal force and is wound on the inner roller (6) The fishing line (10) is stretched outwards. This process is done while the head is currently on the ground. It was based on the principle of triggering the mechanism by striking it. Scythe head (7) 35 The rotation of the inner pulley (6) is limited by the pulley turning lugs (11). Thus 8 Each time the system is triggered, a certain length of fishing line (10) is extended. User the scythe head which can be mounted from the drive shaft connection (16) to the extension holding tube (2) (7) It can be used by holding onto the handles.

(15) can trigger it, while with the sensor it has (3.1) it can receive acceleration and vibration information. always use the fishing line (10) by triggering the magnet (15) at certain time intervals. It ensures that its length remains at a certain level. (If the length of the fishing line (10) shortens Changes occur in the acceleration and vibration data of the scythe head (7). Control unit (3) 10 Based on these changes, it was decided that the line (10) needed to be extended and the electromagnet (4) triggers the windings.) Thus, more efficient cutting performance is obtained while at the same time Over time, the head can also be integrated with robotic systems, and cutting operations can be performed by robots or It allows it to be done by any walking system. The inner roller (6) top In section (13), a magnetic material (14) for the magnetic flux path is used depending on the needs. 15 It can be found. Magnetic material (14) or directly on the reel, strong permanent. The magnets (15) are positioned in such a way that they can have the same or different poles. Thus When the electromagnet coils (4) are triggered, the magnets (15) push into the inner coil (6) or The pulley creates an opposing force against the spring force, preventing rotation. The inner pulley (6) comes free from its claws (11) and falls free, with centrifugal force the inner 20 By providing limited rotation of the reel (6), the lengthening of the line (10) and the line exit The fishing line (10) is automatically extended outwards through the adapter (8).
