Description:FIELD
The present disclosure generally relates to tractor implements, more particularly to systems connecting the implements to the PTO shafts of the tractors.
BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.
A tractor is typically provided with a wide range of implements which is chosen as per the requirements and connected to the PTO shaft of the tractor to enable fulfillment of the required function. Conventionally, the connection of the implement with the tractor is done manually while taking into consideration the setting parameters pertaining to the depth and draft of each implement, because if the depth and draft with respect to the ground is kept low, the implement can be damaged. Therefore, the user has to ascertain the depth and draft before the implement is connected by trial and error methods. This procedure takes a lot of effort and time, apart from taking a toll on the life of the components.
There is therefore felt a need for a system that alleviates the aforementioned drawbacks.

A system (100), of the present disclosure, for facilitating attachment of an implement (10) to a tractor will now be described in detail with reference to Figure 1 through Figure 2.
The system (100) comprises an input module (105), a control module (110) and an actuator (120). The input module (105) is configured to facilitate selection of an implement (10) from a plurality of implements (10). The input module (105) is configured to generate a selection signal upon selection of the desired implement (10). The control module (110) is configured to cooperate with the input module (105) to receive the selection signal. The control module (110) is configured to determine the depth and draft of the implement (10) corresponding to the selection signal and generate an actuating signal. The actuator (120) is connected to the control module (110). The actuator (120) is configured to receive the actuating signal to facilitate attachment of the selected implement (10) to the PTO shaft of the tractor, at the determined depth and draft.
The system (100) helps in controlling draft and depth of the implement (10) while attaching the implement (10) to the PTO shaft.
The system (100) includes a plurality of sensing units (125A, 125B, 125C) configured to sense a plurality of parameters corresponding to the type of the implement, and is further configured to generate a plurality of sensed values.
In an embodiment, the implements (10) are selected from the group consisting of a cultivator, a plough and a rotary tiller.
As shown in figure 2, the control module (110) includes an analog-to-digital converter (112) configured to cooperate with the input module (105) to receive the selection signal. The selection signal is analogous in nature. Hence, the analog-to-digital converter (112) is configured to convert the selection signal to a processed value having a digital nature, and transmit the same.
The control module (110) further includes a memory (114), and a crawler-and-extractor unit (116). The memory (114) has a set of look-up tables corresponding to the plurality of parameters stored therein, wherein each look-up table has a first list of stored values corresponding to the type of implements (10) and a second list of stored values corresponding to the depth and draft of the implements (10). The crawler-and-extractor unit (116) is configured to cooperate with the sensing units (125A, 125B, 125C). The crawler-and-extractor is configured to receive the sensed values, and is further configured to crawl through the look-up tables and extract a first stored value and a second stored value corresponding to the received sensed value.
The control module (110) also includes a comparator (118) configured to cooperate with the analog-to-digital converter (112) to receive the processed value, and further configured to cooperate with the crawler-and-extractor to receive the first stored value and the second stored value therefrom. The comparator (118) is configured to compare the first stored value with the processed value, and is further configured to generate the actuating signal, based on the second stored value, if the first stored value equals the processed value.
In an embodiment, the parameters are selected from the group consisting of weight of the implement, proximity of the implement (10) to the PTO shaft, and the angular velocity required to be transferred to the implement (10). In another embodiment, the system (100) includes a load sensor for sensing the weight of the implement, a proximity sensor for sensing the proximity of the implement (10) to the PTO shaft, and a speed sensor for angular velocity required to be transferred to the implement (10) from the PTO shaft.
In an embodiment, the input module (105) includes a plurality of switches provided on the dash panel of the tractor. Each switch is configured to correspond to an implement (10) to facilitate selection thereof.
In another embodiment, the input module (105) includes a programmed application that facilitates selection of the implement (10). The application could be uploaded on a remote control device selected from the group consisting of mobiles, laptops, palmtops, and desktops.
In one embodiment, the input module (105) is remotely connected to the control module (110). In another embodiment, the input module (105) is wired to the control module (110).
In an embodiment, the actuator (120) is a motor. In another embodiment, the motor includes a solenoid valve that helps in hydraulically/pneumatically actuating the motor to facilitate attachment of the implement (10) with the PTO shaft, and in easing the operation to increase the productivity.
In a first exemplary embodiment, as shown in Figure 2, a user is equipped with a remote control device having an application that allows the user to select attachment of a particular implement (10) with the tractor. The user desires attachment of a cultivator with the tractor, and hence chooses the cultivator option on the application. Upon choosing the cultivator option, the application generates a cultivator selection signal. The analog-to-digital converter (112) of the control module (110) receives the cultivator selection signal and converts the signal to a processed value. The processed value is received by the comparator (118).
At the same time, the load sensor, the proximity sensor and the speed sensor are activated to detect the weight of the implement, the proximity of the implement (10) to the PTO shaft, and the angular velocity required to be transferred to the implement (10) from the PTO shaft, and generate respective sensed signals. In case of the cultivator, if the weight of the implement (10) sensed is less than 200kgs, the proximity of the implement (10) to the PTO shaft is absent, and no angular velocity is required to be transferred to the implement, the crawler-and-extractor infers that the sensed implement (10) is the cultivator. The crawler-and-extractor receives the sensed signals, and crawl through the look-up tables to extract a first stored value based on the sensed signals. The first stored value defines that the type of the implement (10) sensed is a cultivator. Further, the crawler-and-extractor extracts a second stored value which defines the depth and draft required for the attachment of the cultivator.
Since, the inferred implement (10) and the selected implement (10) are the same; the comparator (118) generates the actuating signal based on the second stored value to enable attachment of the cultivator at the determined depth and draft.
The actuator (120) receives the actuating signal and proceeds to attach the cultivator to the PTO shaft.
In a second embodiment, if the desired implement (10) is a plough, the governing conditions are that the weight of the implement (10) is more than 200kgs, the proximity of the implement (10) to the PTO shaft is absent, and no angular velocity is required to be transferred to the implement (10).
In a third embodiment, if the desired implement (10) is a rotary tiller, the governing conditions are that the weight of the implement (10) is more than 200kgs, the implement (10) should be proximal to the PTO shaft, and angular velocity is required to be transferred to the implement (10).
The user does not need to perform a trial and error method for cross-checking the depth and draft every time the implement (10) has to be connected, thereby reducing the wear of the components. Therefore the time required for attaching the implement (10) reduces and the productivity increases. Further, the system (100), of the present disclosure, eliminates the dependency on levers and switches, and ensures that the manual intervention is also reduced, which in turn ensures safe and secure operation while handling the implements (10).
The foregoing description of the embodiments has been provided for purposes of illustration and not intended to limit the scope of the present disclosure. Individual components of a particular embodiment are generally not limited to that particular embodiment, but, are interchangeable. Such variations are not to be regarded as a departure from the present disclosure, and all such modifications are considered to be within the scope of the present disclosure.
