Instead of the elements, it is powered by a hydraulic motor that takes power from the tractor's hydraulic system. an actively rotated, conical geometry and a helical screw on its outer surface The soil is rotated using a rotary conical scraper tip with a toothed blade profile. a tillage system that enables processing of soil using the principle of cutting and breaking It is related. The technical effect of the invention is 15 thanks to the actively rotating rotary conical scraper tip. Reducing the gross friction forces generated between the soil and the equipment, Working the soil with lower traction force reduces the load on the tractor and fuel consumption. reducing consumption, increasing work speed and at the same time expanding the reach The areas can be processed. Also, the legs can be removed and attached to the main supporting frame. It can be attached in a snap-on manner and the rotating conical scraper bits are available in 20 different diameters. Thanks to its interchangeable design, the system can be used according to tractor power, operating conditions, etc. It can be easily adapted to the width and soil conditions, and this situation It provides operational flexibility, ease of maintenance, and operational efficiency. 2 State of the Art In agriculture, tillage operations directly affect yield in plant cultivation. This is one of the most important applications, and for this purpose, different types of tillage machines are used. These machines have been developed. The main ones among these machines are moldboard plows and disc plows. These include sliding plows, rotary plows, and chisel plows. 5 Plows, commonly used in known technology, are fixed tools that penetrate the soil. The soil is subjected to coarse friction force through the scraping feet and protective fenders. It operates by cutting, lifting, and knocking over. These machines are operated with the help of a tractor. It works by pulling it out, and in this way weeds and plant residues (stubble) are removed from the soil. It is buried underground, the soil is aerated and prepared for planting. 10 However, the fixed protective mudguard and the height difference created by the contact of the feet with the ground... Friction creates a significant traction load on the tractor, this situation This leads to high fuel consumption, equipment wear, and long operating times. It opens. Chisel plows, on the other hand, generally work in deep layers without turning over the soil, 15 By working, it breaks up the hard layer and loosens the soil. However, this Since these systems also operate entirely based on brute friction force, the soil The resistance remains high and the load on the tractor cannot be reduced. Furthermore, this... When the scraping tip on machines wears out, it is usually the foot or guard that is affected. The entire fender needs to be replaced, which will increase the maintenance cost to 20. It increases. The current technology offers various production methods to address these problems. systems have been improved. For example, in patent document number US3735817A, a tractor is described as being pulled by a tractor. 25 mounted on the frame so that it can rotate freely around a horizontal and angled axis. a plow blade with a spiral (helical) structure and a sharpened outer edge It is explained that the knife in question is a reaction to the soil's response to it. It passively rotates using its own force, thereby reducing traction resistance. However, the document states that the spiral blade is connected to the tractor's oil pressure. actively driven by a hydraulic motor powered by its mechanism, 30 a conical scraper tip geometry, the nose portion of the tip separately 3 can be changed or the foot can be protected against stony surfaces by a spring mechanism. There is no statement regarding its protection. Patent document number US4512414A describes a body containing hydraulic fluid. A reservoir was created for it, and a hydraulic system was used to drive the rotating blade shaft that worked the soil. a rotary tillage machine driven by a motor 5 It is explained. However, the document states that it has a conical body and a spiral screw on its outer surface. a scraper tip structure with a toothed blade profile, the nose of the scraper tip can be changed separately or the foot can be attached to the main chassis flexibly via a spring. There is no solution for connecting it in this way. Patent document number US4200157A describes 10 types of tillage implements for chisel-type soil preparation. Used for; large stones that can flex on hard or frozen surfaces during operation. When encountering a stationary obstacle, such as a fixed one, it activates and moves the foot upwards. allows its movement and automatically returns to its original position after the obstacle is overcome. A rotating spring-loaded foot fixing mechanism is described. However, The document states that at the lower end of the foot is a rotating conical 15 that is driven by a hydraulic motor. a structural description relating to the scraper tip or the spiral blade profile of that tip It is not being done. Patent document number US4813491A describes the shank (foot) of a tillage implement. made of wear-resistant, hard material, attached to the lower end with a wedge connection. A scraping tip that is designed and can be removed and replaced separately is described. 20 However, the document states that the replaceable engraving tip has a conical and rotary design. by being driven by a hydraulic motor or by moving the soil on its outer surface There is no description of a threaded profile resembling a spiral screw. A common feature of the examined patent documents is the different tillage processes. elements (friction-reducing rotary blade, hydraulic motor drive, foot guard 25 Their mechanism is to offer partial solutions for (replaceable scraping tip) issues. However, none of the documents in question mention the tractor's oil pressure. driven by a hydraulic motor powered by an external mechanism a rotary conical scraper with a helical screw-toothed blade profile on its surface The tip; the replaceable conical tip at the nose section protects the foot against stony surfaces. 30 a spring mechanism, with a soil-splitting disc behind it that pre-cuts the soil. 4 field protection fender, replaceable blades, rear roller and rear rake a land where elements are brought together in an integrated and modular structure The processing system is not described. In conclusion, in the current systems used in known technology; tillage Friction-based operation leads to high energy and fuel consumption. 5 Because the scraping feet and protective fender are fixed in structure, they are hard or It is at risk of breaking on rocky surfaces; worn end pieces must be removed separately. It is not possible to change it, and the working width of the legs depends on the tractor's power. It cannot be easily adjusted accordingly. Given these disadvantages, It reduces friction, the worn ends can be replaced separately, and it's suitable for stony surfaces. It has flexible protection and can be modularly adjusted according to the tractor's power. A new tillage implement is needed. Our invention overcomes the disadvantages of the existing technology, which has been described in detail above. It was developed to eliminate the need for conventional plow and chisel plow systems. In contrast, instead of a fixed scraping foot and protective fender, the tractor's oil pressure is 15 with a conical blade scraping tip rotated by a hydraulic motor It is equipped with this system. This allows for the reduction of coarse friction between the soil and the equipment. This significantly reduces the pulling load on the tractor and decreases fuel consumption. This shortens the processing time. The conical geometry of the rotary scraper tip allows the tip to penetrate the soil gradually. to enable it and the sudden resistance forces that occur during the initial entry. It reduces the direction of advancement of the scraper tip. centering, gradually increasing from the tip of the soil to the wider stem section. contributes to its breakdown and more balanced movement within the soil. It provides this. Thanks to the rotating movement, the 25 cm gap between the soil and the scraper tip... A significant part of friction-based sliding motion is shearing and tearing. is converted into traction resistance, thus transferring it to the tractor. is being reduced. Purpose and Technical Advantages of the Invention The purpose of the invention is to replace the classic plow and chisel plow used in agricultural soil tillage processes. The need for traction force due to high friction that arises in blasting systems, high fuel consumption, energy losses during soil cultivation, constant 5 The scraping elements are at risk of breaking in stony and hard surfaces, and the worn parts are all... enabling the resolution of technical problems such as the necessity of changing it. The goal is to develop a soil tillage system. To this end, the invention involves the use of hydraulic power obtained from the tractor's hydraulic system, 10 actively operated via hydraulic motors located at the bottom of each leg a rotating, conical blade with helical screw teeth on its outer surface It is based on the principle of transferring the profile to a rotary conical scraper tip. Thus, in classical systems, the soil is dragged away by stationary scraping elements. instead of processing, the soil is processed using the principle of rotary cutting and crushing. 15 This is provided by the coarse friction forces that occur between the soil and the equipment. by reducing the traction load on the tractor, energy requirements and fuel consumption. is being reduced. Another purpose of the invention is to locate the 20 at the nose of the rotating conical scraper tip. Thanks to the replaceable conical tip, only the worn part needs to be replaced. by reducing maintenance and spare parts costs, and shortening maintenance times The goal is to shorten the lifespan of the equipment and increase its service life. Another purpose of the invention is to position the spring 25 between the foot and the main supporting chassis. its mechanism allows it to strike hard ground elements such as stones, rocks and similar objects by absorbing the impact loads generated in this way, the feet, hydraulic motors and To prevent damage to the rotary conical scraper tips and to adapt the system to different terrains. The goal is to ensure that it operates safely under these conditions. 6 The invention includes a soil splitter located at the front of the rotating conical scraper tip. The disc allows penetration into the soil by splitting the soil before it reaches the scraping tip. It reduces resistance; the protective fender behind it is cut and It directs the loosened soil to the surface in a controlled manner. The back of the system In section 5, the soil is broken up and leveled thanks to the roller and rake. They are being prepared and made ready for planting. Thus, unlike classical systems...

It is put into working position and all structural loads of the system are on the main supporting chassis (2) 20 It is carried by. The working depth of the screw conical plow (1) is three of the tractor (A). Raising and lowering the point suspension system, the feet (3) main carrier chassis (2) Changing the vertical positions on the rear roller (13) height adjustment of its position or the combined application of these methods This can be determined in this way. 25 During operation, hydraulic power is obtained from the tractor's (A) oil pressure mechanism, oil hoses (6) positioned at the lower end of each foot (3) The hydraulic power is transmitted to the hydraulic motors (4). When necessary, this hydraulic power is transferred to the main carrier. It is supported by the oil pressure tank (5) located on the chassis (2). 30 In an alternative application, the hydraulic motor (4) can be used as an option to perform the same function. An electric motor can also be used in this way. The rotary motion produced by the hydraulic motor (4) is transmitted through the motor's output shaft. direct or coupling, intermediate shaft, gear transmission mechanism, reducer or equivalent 5 The motion is transmitted to the rotating conical scraper tip (7) via a motion transmission element. Adjustment of the flow rate and pressure of the hydraulic fluid transmitted to the hydraulic motor (4). the rotational speed of the rotating conical scraper tip (7) and the torque it applies to the soil It is controllable. Thus, the system can adapt to different soil hardnesses and working depths. and adaptable to terrain conditions. 10 The rotary conical scraper tip (7) is one of the fixed scraping feet used in classical systems. Unlike others, it penetrates the soil by actively rotating around its own axis. It rotates. The conical geometry of the conical scraper tip (7) allows the tip to enter the soil gradually. By providing this, it reduces the sudden resistance forces generated during the initial contact. Conical structure 15 at the same time the scraper tip is centered in the direction of advancement and the soil it gradually splits into smaller sections, from the nose to the wider body. It contributes. The spiral (helical) screw thread 20 located on the outer surface of the rotary conical scraper tip (7) The blade profile is the way an auger or drill bit works during rotational motion. In a similar principle, it cuts and breaks up the soil, and the axis of the scraper tip... It guides along its entire length. The helical profile in question can be single-start or multi-start. in an initial structure, with a fixed or variable helix pitch. It can be configured. Number of blades, helix angle, helix pitch, blade height and thickness; 25 depending on the hardness of the soil to be tilled, the target working depth, the power of the tractor, and It can be modified according to the desired soil fragmentation effect. Thanks to the active rotation of the rotary conical scraper tip (7), the classic fixed scraping is eliminated. The significant effects of drift and gross friction that occur in these systems are 30%. The section is converted into a rotational cutting and crushing motion. Thus, the soil is processed... 11 By reducing the resistance between the equipment, the traction load on the tractor is increased and... This helps reduce the associated energy demand. The rotary conical scraper tip (7) is aligned with the direction of advancement of the helical blade profile. It can be rotated clockwise or counterclockwise. 5 depending on the application. The direction of rotation can be fixed, or it can be adapted for bidirectional operation. arrangeable. The soil splitting disc (10) located at the front of the rotary conical scraper tip (7), advances By first cutting the soil in the direction of the entry of the rotating conical scraper tip (7) into the soil and 10 It facilitates the scraping process. The soil splitting disc (10) reduces the force applied by the soil. As a result, it rotates freely around its own axis, cutting through the soil. The disc height, angle and distance to the rotary conical scraper tip (7) to the working depth And it can be constructed as a fixed or adjustable structure depending on soil conditions. The replaceable conical tip (8) located at the nose of the rotary conical scraper tip (7), the first to come into contact with the soil and the most subject to wear during use It is a section.

The connection structure, the torque occurring during operation and 20 unintentional loosening of the replaceable conical tip (8) under axial forces It is arranged in such a way as to prevent the entire rotating conical scraper tip (7) from being damaged. Without needing to replace anything, only the worn nose section can be removed and replaced with a new one. replaceable. Rotary conical scraper tip (7), replaceable conical tip (8) and helical blade profile; to withstand wear, impact, torsional and axial forces generated during operation They can be manufactured from metallic materials. These parts include hardened steel, alloy steel, cast material or surface with wear-resistant coating. It can be manufactured from reinforced equivalent materials. Helical blade profile rotates 30° The conical scraper tip (7) can be formed as an integral part of the body, 12 It also consists of blade segments that can be removed and replaced separately when they wear out. It can come. The soil is cut, broken up and loosened by the rotary conical scraper tip (7), Thanks to the protective mudguard (11) located behind the scraper tip, it can reach up to 5 and is carried to the surface by being directed sideways. The curved protective fender (11) Its structure allows for the controlled turning of the loosened soil and the stubble on the surface, It allows weeds, roots, and similar plant debris to be buried underground. The angle of inclination, height of the protective fender (11) and the rotating conical scraper tip (7) 10 The distance can be fixed or adjustable depending on the desired amount of soil tilting. It can be formed in this way. The wear on the protective fender (11) Durable replaceable blades (12) prevent soil from being thrown around uncontrollably. reducing and protecting the heavily exposed surface of the mudguard to the soil. It extends the service life by protecting against wear and tear. 15 If the foot (3) hits a stone, rock or similar hard material during the work In this case, the spring (9) is positioned between the foot (3) and the main carrier chassis (2), by absorbing the resulting impact load, the foot (3) moves backward, upward or to a limited extent It allows the foot (3) to move in both directions. Thus, the hydraulic motor 20 (4) and the risk of damage or breakage of the rotary conical scraper tip (7) is reduced. Spring (9), compression spring, tension spring, torsion spring or equivalent elastic support It can consist of elements. After the foot (3) overcomes the hard material, the spring (9), It allows the foot to return to its working position. Spring stiffness or front 25 The amount of loading depends on the ground conditions and the rotary conical scraper bit (7) used. It can be adjusted according to the measurements. During the processing process, the protective fender (11) was brought to the surface and overturned. soil is 30 by the rear roller (13) located at the rear of the system. The large pieces of soil are broken down and reduced in size. The rear roller (13) 13 Then the rear harrow (14) is positioned to level the cultivated soil surface. It homogenizes the soil by doing so. Thus, plowing the field breaks down the soil, The overturning and surface leveling operations are completed in a single pass, making the soil ready for planting. preparation is ensured.
