Description
A CONTROL SYSTEM FOR THREE-POINT LINKAGE
TECHNICAL FIELD
The present invention relates to a control system which provides control of a three-point linkage used in connecting agricultural equipment to tractors.
PRIOR ART
Agricultural tools and equipment are connected to tractors by means of three-point linkages. Tools and equipment are connected to tractors in an easy manner by means of three-point linkages. Moreover, by obtaining different operation positions, power is transferred to the equipment in an effective manner.
Three-point linkages are lifts which operate according to hydraulic principle. The control of the system is provided mechanically or electronically. In the connection of the equipment to the vehicle, connection arms which are movable through three points are used. The control of the connection arms is realized by means of control buttons mechanically or electronically. During the assembly of the equipment to the vehicle, the user needs an assistant for providing control or the user leaves the equipment and goes to the control panel for making adjustment.
The buttoned controls frequently used as the control panel are provided on the mudguard of the vehicle. The connection of the equipment to the system by the operator and the access of the operator to the control panel at the same time are not always possible. In this case, the operator firstly realizes height adjustment of the system in the control panel and afterwards, the operator provides movement of the equipment for connecting the equipment to the system. If the height of the system has not been adjusted in a suitable manner, adjustment shall be made again through the control panel. The same processes are repeated until the assembly of the equipment is realized.
During connection of the agricultural equipment to the three-point linkages, repeating the operation steps leads to extension of the operation and thus, leads to time and cost loss.
As a result, because of all of the abovementioned problems, an improvement is required in the related technical field.

In order to realize all of the abovementioned objects and the objects which are to be deducted from the detailed description below, the present invention is a control system having a control unit associated with a hydraulic unit where at least one control valve is positioned which provides upward-downward movement of the three-point linkage during connection of equipment to the three-point linkage. Accordingly, at least one wireless control device is provided which sends data in a wireless manner by means of a transmitter to a receiver provided on a communication unit associated with said control unit and which provides sending of the operation commands from the control unit to the valve. Thus, the operator can provide connection process easily in a stand-alone manner and without needing to leave the equipment.
In a possible embodiment of the present invention, the wireless control device and the communication unit are configured to communicate by means of short-distance RF communication protocol, particularly by means of bluetooth. Thus, the operator can handle the equipment and at the same time, he can control the three-point linkage.
In a possible embodiment of the present invention, the wireless control device comprises at least one control interface. Thus, the operator can select the desired command without being subjected to physical stress.
In a possible embodiment of the present invention, at least one position sensor is provided which is connected to the three-point linkage.

BRIEF DESCRIPTION OF THE FIGURES
Figure 1 is a representative schematic view of the subject matter control system.
DETAILED DESCRIPTION OF THE INVENTION
In this detailed description, the subject matter control system (10) is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.
In Figure 1 , the schematic view of the subject matter control system (10) is given. Accordingly, there is at least one control unit (30) connected to at least one three-point linkage (40). By means of the commands given through at least one internal control interface (31) associated with the control unit (30), at least one control valve (41) is controlled and a hydraulic unit (42) is operated. Depending on this, the upward-downward movement of the three-point linkage (40) can be controlled.
There is at least one communication unit (50) connected to the control unit (30). There is at least one wireless control device (20) connected to said communication unit (50). The commands entered through a control interface (21) provided on the wireless control device (20) are transferred to a receiver (51), provided at the communication unit (50), by means of a transmitter (22) and from there, said commands are transferred to the control valve (41), provided at the three-point linkage (40), by means of the control unit (30). Thus, by means of the commands given from the wireless control device (20), the upward-downward movement of the three-point linkage (40) is controlled.
In more details, when the operator desires to assemble equipment to his tractor, he uses the three-point linkage (40). After the tractor is brought near the equipment, the operator needs the sensitive movements of the three-point linkage (40) for realizing connection. In this case,
the operator controls the three-point linkage (40) by means of the commands provided on said control interface (21). The wireless control device (20) provides transfer of the commands of the operator to the control unit (30) without using any cable, wire, etc. equipment. Said transmitter (22) provides transfer of the commands, entered through the control interface (21), to the receiver (51) in the communication unit (50) and to the control unit (30) from there. Thus, the control unit (30) transforms the commands of the wireless control device (20) into movement in the three-point linkage (40). The control valve (41) in three-point linkage provides oil flow of the hydraulic unit (42) in the direction of the commands of the control unit (30).
By means of the subject matter control system (10), the problems which occur during connection of equipment to the tractor by the operator are eliminated. The operator can provide the connection process in a stand-alone manner and without needing to leave the equipment.
The subject matter control system (10) is essentially connected to at least one position sensor (43) provided on the three-point linkage (40). Said position sensor (43) controls the movements in the three-point linkage (40) according to the commands given, and confirms the correctness of the position. The position sensor (43) transfers the detected position information to the communication unit (50). The information coming from the position sensor (43) are recorded to a memory unit (52) provided in the communication unit (50). Moreover, when fault related to the position is detected, warning can be given by means of at least one warning marker (23). Said warning marker (23) can be positioned on the wireless control device (20) or on the tractor.
In the subject matter control system (10), it is possible that the three-point linkage (40) can be controlled both through the internal control interface (31) and through the control interface (21) in the wireless control device (20). In other words, by means of the subject matter control system (10), remote control can be provided in addition to the operation manner of the three-point linkages (40) used in the present art. Thus, functionality is provided to the present systems.
In a possible embodiment of the present invention, the wireless control device (20) can be a specially designed control device, a key-holder, cellular phone, tablet or computer. Moreover, the wireless control device (20) and the control unit (30) communicate by means of a special matching signal. Thus, the control device (20) can operate only in the tractor where the matched control unit (30) is positioned.
Moreover, thanks to said structure of the subject matter control system (10), the subject matter control system (10) can be applied on the three-point linkages, used in the present art, without making any changes. The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
