DESCRIPTION
FIELD OF INVENTION
[0001] Embodiments of the present disclosure relate generally to agricultural machineries for agricultural purpose, specifically a system and apparatus for climbing up a tree to perform various tasks.
RELATED ART
[0002] The labour scarcity is one of the challenges in farming. Most of the crops such as areca nut, coconut, coffee etc. affected due to labour scarcity. Trees such as coconut, areca nut grows to a height of about 50-70 feet. Manual labourers are required to climb the trees to harvest and perform other activities. For example, often a human labourer is required to climb the tree twice a year for spraying pesticide and thrice a year for harvesting the crop. The labourers are required to climb the tree using muscle power and physical exertion thereby increasing the time and cost of performing the farming tasks.
[0003] Farmers or labourers climb the trees and spray pesticide by manual process for cultivating their farms. Many farmers developed their own machines or methods for spraying pesticide. The manner in which an example conventional sprayer machine employed is described in further detail below.
[0004] Fig.1 is an example diagram of conventional sprayer machine. As shown conventional sprayer machine 100 comprises pumping system 180 and sprayer unit 190. The pumping system 180 further comprises compression chamber 120, filter 110, pumping system holder 130 and lever 170. The sprayer unit 190 also comprises sprayer arm 150 and nozzle 160. Each unit is described in further detail below.
[0005] The pumping system 180 pumps the pesticide to the crops through the sprayer unit 190. The compression chamber 120 passes the pesticide from the tank (tank stored with pesticide) to the sprayer 190 through the pipe 140. The compression chamber 120 is mounted on the pumping system holder 130. The filter 110 removes the dust from the pesticide in the tank and passes the pesticide to the compression chamber 120.The compression chamber 120 pumps the pesticide with the help of the lever 170 operated by the user manually.
[0006] The sprayer unit 190 sprays the pesticide to crops. The sprayer unit 150 receives pesticide from the pumping system 180 through pipe 140. The sprayer arm 150 is held by the user to set the position where spraying is required. The nozzle 160 is used to spray or spread the pesticide for a certain area of the crop. For example, the conventional sprayer machine 100 is used to spray the pesticide for tall grown trees such as areca nut, coconut etc with the help of additional instrument (For example, a long rope for height adjustment) and sometimes with the necessity of labourers to climb the tree for successful spraying. The conventional sprayer machine 100 as shown in Fig.1 is operated by at least two people (one is to maintain pumping system 180 and another one is to maintain sprayer unit 190).

[0060] In block 1020, send image to the processor of ground control unit. The radio frequency is transmitted to the ground control unit through the transceiver of climber unit. The transceiver of ground control unit receives the radio frequency signal, decodes the image/video information, and forwards the image/video information to the processor.
[0061] In block 1030, extract the features of photo/video. The processor and image processing section mutually work to extract the features of the input photo/video information and extracts the critical information (feature) from the photo/video. The critical information (features) from the photo/video may be extracted by considering the crop’s colour such as blackish green, brown or blackish yellow etc. In one embodiment, the feature extraction may be dependent on the color along with diameter and size of the crop because colour of the crop may changes from season to season depending on weather and land.
[0062] In block 1040, match input image with the image stored in storage unit. The processor and image processing section refer the image stored in the storage unit (not shown) to compare with the input image/video signal. In one embodiment, the processor and image processing section analyze the given input signal with the stored image/video signal for further extraction of information from the input photo/video signal.
[0063] In block 1050, the processor checks the critical information retrieved from input signal with that of image/video signal stored in the storage unit. If the critical information of input signal matches with image/video signal stored in the storage unit, then the control is transferred to block 1060, otherwise the control is transferred to 1060.
[0064] In block 1060, spray pesticide to the affected area of the crop/tree. The results of the processor and image processing section are displayed to the operator. The operator may make a decision accordingly to spray the affected part of the tree. The operator also decides the amount of pesticides and time of spraying (using a timer) the affected area. The operator controls the sprayer unit with the help of components in ground control unit and climber unit. In one embodiment, the processor of ground control unit automatically decides the amount of pesticides and time required (with the help of supplied critical information) to spray the infected area. The processor also prepares the control signal (for the sprayer unit of climber unit) and passes them to the processor unit (of climber unit) to manage the spraying operation independent of the operator.
[0065] In block 1070, move arms of sprayer unit to cover other portion of same tree/crop or other neighboring trees. In one embodiment, the arms of sprayer unit are adjusted to scan the affected areas/portions of neighboring trees, control is transferred to 1010, and the operation is repeated. In another embodiment, the climber unit may have a detachable sprayer unit. In another embodiment, the climber unit is also configured to accommodate a cutter unit (a device) in the place of sprayer unit to twist, cut or pluck areca nut bunches from the tree.
[0066] While various embodiments of the present disclosure have been described above, it should be understood that they have been presented by way of example only, and not limitation. Thus, the breadth and scope of the present disclosure should not be limited by any of the above-discussed embodiments, but should be defined only in accordance with the following claims and their equivalents.
