[0001] MACHINING-BASED DISC GRINDING UNIT

[0002] FIELD OF THE INVENTION

[0003] The invention relates to a grinding unit configured for sharpening soil tillage discs.

[0004] BACKGROUND OF THE INVENTION

[0005] Soil tillage discs are rotary disc-shaped tools used in agricultural operations to cut and break up the surface of the soil. They provide the necessary conditions for preparing a proper seedbed in the fields and gardens where they are used. These discs generally perform processes such as loosening, fragmenting, and aerating the soil, as well as removing surface weeds. The discs are mounted in parallel rows and operate efficiently in both dry and moist soil by adapting to the challenging conditions of the field. The angle between the discs determines the tillage depth and cutting efficiency, while their rotary movement allows the soil to be processed with reduced energy consumption. At the same time, they improve the soil’s water retention capacity, creating a more favorable environment for plant growth.

[0006] In addition, the production of soil tillage discs includes a sharpening process that must be carried out with precision. During production, it is aimed that the discs possess maximum sharpness and durability. This ensures the highest quality in soil tillage. The manufactured raw discs generally undergo surface treatment and sharpening processes. However, in traditional methods, sharpening the discs manually or with standard machines is timeconsuming and makes it difficult to achieve the desired uniform sharpness. Proper sharpening of the discs is critically important for ensuring their long service life and high performance. During manual sharpening processes, improper fixation of the discs hinders the achievement of homogeneous sharpening. Furthermore, in cases where the discs need to be sharpened quickly and efficiently on the production line, existing systems slow down the workflow and make it difficult to obtain proper sharpening.

[0007] As a result, all the abovementioned problems have made it necessary to make an improvement in the relevant technical field.

[0008] SUMMARY OF THE INVENTION The present invention relates to a soil tillage disc grinding unit intended to eliminate the above-mentioned disadvantages and to introduce new advantages to the relevant technical field.

[0009] An object of the invention is to provide an efficient, easy, and fast grinding unit in the production process of soil tillage discs.

[0010] In order to achieve all the objectives mentioned above and those that will become apparent from the detailed description below, the present invention is a grinding unit configured for sharpening soil tillage discs. Accordingly, the novelty lies in that it comprises at least one first body having at least one first holder and at least one second holder, between which the disc to be subjected to the grinding process is placed; at least one of the said first holder and the said second holder being connected to a drive element that generates drive to rotate the disc about its own axis; at least one second body comprising at least one tool holder, to which at least one cutting tool that performs the grinding process is removably connected, the second body being positioned in the vicinity of the first body for grinding the disc held between the first holder and the second holder; and the first body and the second body being connected to a main frame such that at least one of them has mobility relative to the other to move closer to or away from the other. In this way, soil tillage discs can be sharpened quickly, automatically, and properly.

[0011] A feature of a possible embodiment of the invention is that the holder drive element is configured to rotate the soil tillage disc about a first axis perpendicular to the ground. In this way, a more homogeneous grinding process is achieved.

[0012] A feature of another possible embodiment of the invention is that at least one of the first body and the second body is connected to at least one body drive element in order to move closer to or away from the other on at least one guide element provided on the main frame. In this way, soil tillage discs of different thicknesses can be easily sharpened.

[0013] A feature of another possible embodiment of the invention is that the first body comprises at least one protective frame that provides shielding to prevent the chips generated during grinding from scattering into the environment. In this way, occupational health and safety is ensured during the operation.

[0016] DETAILED DESCRIPTION OF THE INVENTION

[0017] In this detailed description, the subject of the invention is described utilizing examples only for clarifying the subject matter such that no limiting effect is created.

[0018] Figure 1 shows a representative isometric view of the grinding unit (10) configured for sharpening soil tillage discs, which is the subject of the invention. Accordingly, the soil tillage disc is a tool consisting of a circular metal structure used in agriculture to cut, break, and mix the soil. It is generally used in machines known as disc plows or disc harrows. The discs break up the soil, enable aeration, and prepare the soil for planting. Accordingly, the invention comprises at least one grinding unit (10) for the grinding process involved in the production of soil tillage discs. The grinding unit (10) enables the soil tillage discs to be sharpened precisely and efficiently. The grinding unit (10) comprises at least one main frame (11). The said main frame (11) serves the role of carrying the main structural elements of the machine. The main frame (11) constitutes the chassis of the grinding unit (10). The grinding unit (10) is composed of two bodies. The grinding unit (10) comprises at least one first body (20) and at least one second body (30). The said first body (20) and second body (30) are connected on the main frame (11). The first body (20) and the second body (30) are connected in a manner that they are in the vicinity of each other. The first body (20) forms the main structure where the disc is fixed and rotated during the grinding process. The first body (20) comprises at least one first holder (21 ) and at least one second holder (22) for fixing the soil tillage disc and rotating it during the grinding process.

[0019] The said first holder (21) and second holder (22) are connected in the vicinity of each other. A gap is provided between the first holder (21 ) and the second holder (22) through which the disc can be easily inserted. In the preferred embodiment, the first holder (21 ) has a circular shape. In the preferred embodiment, the second holder (22) has a circular shape. At least one of the first holder (21 ) and the said second holder (22) comprises at least one holder drive element (40) that generates drive to rotate the disc about its own axis. The holder drive element (40) is connected on the main frame (11). The holder drive element (40) enables the disc to rotate about its own axis for the grinding process. The holder drive element (40) is configured to rotate the soil tillage disc around a first axis (I) perpendicular to the ground. In a possible embodiment of the invention, the first holder (21 ) comprises at least one holder drive element (40) for rotating the disc. The soil tillage disc is seated into a socket on the first holder (21 ). The soil tillage disc is seated into the said socket on the first holder (21 ) and is held by the second holder (22). In this way, the second holder (22) moves toward the first holder (21) along the first axis (I), thereby holding the disc. The first axis (I) is perpendicular to the ground on the first body (20). The first holder (21) rotates the soil tillage disc about the first axis (I) by receiving drive from the holder drive element (40). The second holder (22) is capable of enabling upward and downward movement along the first axis (I). In this way, the second holder (22) moves upward or downward along the first axis (I), thereby holding the disc. While the first holder (21) rotates the disc about its own axis, the second holder (22) is also capable of rotating during gripping. Since the second holder (22) holds the soil tillage disc and is capable of rotating together with the disc during the grinding process, it prevents unwanted movements and vibrations of the disc.

[0020] In another possible embodiment of the invention, the second holder (22) comprises at least one holder drive element (40) for rotating the disc. The second holder (22) comprises a socket for placing the soil tillage disc. The soil tillage disc is seated into the said socket on the second holder (22) and is held by the first holder (21). In this way, the first holder (21) moves toward the second holder (22) along the first axis (I), thereby holding the disc. The first axis (I) is perpendicular to the ground on the first body (20). The second holder (22) rotates the soil tillage disc around itself on the first axis (I) by receiving drive from the holder drive element (40). The first holder (21) is capable of enabling upward and downward movement along the first axis (I). In this way, the first holder (21) moves upward or downward along the first axis (I), thereby holding the disc. While the second holder (22) rotates the disc about its own axis, the first holder (21 ) is also capable of rotating during gripping. Since the first holder (21) holds the soil tillage disc and is capable of rotating together with the disc during the grinding process, it prevents unwanted movements and vibrations of the disc.

[0021] Figure 2 shows a representative side view of the grinding unit (10) configured for sharpening soil tillage discs, which is the subject of the invention. Accordingly, the first body (20) and the second body (30) are connected to a main frame (11 ) such that at least one of them has freedom of movement to move closer to or away from the other. At least one of the first body (20) and the second body (30) is capable of moving closer to or away from the other on a second axis (II). The second axis (II) and the first axis (I) are perpendicular to each other. The second axis (II) extends from the second body (30) toward the first body (20). At least one of the first body (20) and the second body (30) is connected to at least one body drive element in order to move closer to or away from the other on at least one guide element (12) provided on the main frame (11). The main frame (11 ) comprises at least one guide element (12). The said guide element (12) enables at least one of the first body (20) and the second body (30) to move closer to or away from the other. The guide element (12) guides this movement through the drive provided by the body drive element.

[0022] In the preferred embodiment of the invention, the guide element (12) has a bellows-like structure. In this way, the cables located inside the guide element (12) are able to move without folding or breaking. The guide element (12) extends along the first body (20) and the second body (30) on the main frame (11). By receiving drive from the body drive element, the guide element (12) enables the first and second bodies (30) to move toward or away from each other in a controlled manner. In this way, necessary adjustments can be made depending on the thickness or diameter of the disc, and a homogeneous grinding can be achieved by applying appropriate pressure to both surfaces of the disc during the grinding process. At the same time, this mobility allows discs of different sizes to be processed in the grinding unit (10). The second body (30) comprises at least one tool holder (31 ) for grinding the soil tillage disc. The tool holder (31 ) allows the cutting tool to be fixed in the correct position and angle during the grinding of the disc. In the preferred embodiment, the tool holder (31) is positioned on the second body (30) in alignment with the gap between the first holder (21 ) and the second holder (22). The tool holder (31 ) has a structure that allows the cutting tool to be easily mounted and dismounted.

[0023] In this way, it enables the soil tillage discs to be ground at different angles. Additionally, the cutting tool can be brought into contact with the surface of the disc at various angles. The grinding process can thus be performed at the most suitable angle according to the geometry of the discs and the desired shapes. As a result, sharper, smoother, and more uniform grinding is achieved, and the desired grinding profiles can be obtained. Furthermore, in case of wear of the cutting tool, it allows for quick replacement and makes it possible to use cutting tools of different types or sizes. The tool holder (31) comprises a structure that ensures the fixation of the cutting tool. Secure fixation of the cutting tool prevents it from slipping or shifting during the grinding process. In this way, the grinding applied to the surface of the disc becomes more balanced and uniform. Moreover, maximum efficiency is achieved in the sharpness of the discs. This flexibility allows the grinding unit (10) to adapt to various disc types and sizes. Thus, by means of the first holder (21 ), the second holder (22), and the tool holder (31), the soil tillage disc is rotated and ground in a material-removing manner at different angles.

[0024] To prevent chips from scattering into the environment during the grinding of the soil tillage disc, the first body (20) comprises at least one protective frame (13) that provides shielding. The said protective frame (13) prevents the chips from dispersing into the surroundings and helps keep the working area clean. At the same time, it enhances occupational safety during the grinding process and provides significant protection for operator safety. The soil tillage disc, which is held by the first holder (21) and the second holder (22) on the first axis (I) and rotated about its own axis, is ground at desired angles or in desired forms by means of the tool holder (31 ), through the movement of at least one of the first body (20) and the second body (30) toward or away from the other on at least one guide element (12) located on the main frame (11). As a result, this invention provides an advanced solution for grinding soil tillage discs used in agricultural machines at different angles and in a homogeneous manner.

[0025] The protection scope of the invention is specified in the appended claims and cannot be limited to the description made for illustrative purposes in this detailed description. Likewise, it is clear that a person skilled in the art can present similar embodiments in the light of the above descriptions without departing from the main theme of the invention.
