This machine is simple and a person with little technical knowledge can easily assemble it in an ordinary workshop. The switch board is used to control the DC geared motors, windshield wiper pump, nozzle motors etc. When the drive motor is clijber on, the motor rotates the shaft which in turn rotates the wheels.
The remote is used to control the areecanut. The machine can be fitted with pesticide spraying unit or nut plucking tool. In other case, machine used requires long fixing time to attach the machine to the tree and it has certain limitations.
Students of Sahyadri College of Eng develop a low-cost areca nut tree climbing machine!! Areca nuts are collected in a basket.
Selection of the Wheel Average Change in circumference of the tree is taken as 30cm to 50cm. The device consists of a triangular base frame which supports all arefanut components to be built upon.
In this study, considering all the above parameters, a safe, reliable and efficient climbing and spraying machine is designed and fabricated. Nozzle Motor and Pump Nozzle motor is used to control the nozzle attachment for spraying purpose.
The machine should grab the tree firmly cllimber maintain its positions during the operation. The design of the machine is simple enough for farmers to operate. The tension of the spring helps to retain the machine at the required height. Line diagram to calculate Length of the links Figure 2.
The tension maintained by the spring must be good enough to maintain the gripping force between the wheel and the tree. Cutting of the areca nut bunch is also easy with a special type knife of this machine. Once it reaches the required height, the sprayer or plucking tool can be activated from the ground through a remote control.
Remote Control Unit 5. Specifications and Functions of Parts Used 4. Specifications are given below; Volt: This is a unique model which will be hree machine-front of the areca nut industry and in turn will serve as a great help and boon to areca nut farmers.
Sukesh K S Type of entry: The nozzle is positioned near the arecanut with the help of guide way motors and then the guide way motors are switched OFF. TOI Most people think this post is Awesome! To help areca nut farmers reduce dependency on tree climbers Asheesh V Rao, S Siddharth, K Shrihari and Praveen Cljmber P Rao have developed the machine that can reach a height of about meters within a minute. In this tree climbing machine power is obtained from 12V battery through which drive motors are energized.
The students have spent about Rs 42, to develop the machine. The geared motor should be powerful enough to carry the payloads and weight of the machine.
The DC motor used to drive wheel is square climbeer DC motor. Under the guidance of Prof Afecanut Kareem. Motors Five motors are used in this machine, in which 3 motors are used to drive the wheels, other 2 motors are used to controlling the nozzle attachment for spraying pesticides.
Therefore, maintaining sufficient friction force capable of handling the self-weight, maintaining the stability of the structure while in motion, reducing the total weight, and achieving the precise gripping are the important parameters that have to be considered.
To accommodate for change in qrecanut diameter of arecanut tree as the device moves up and down, a spring loaded mechanism is used for exerting sufficient tension required for gripping the tree. The only component which is in contact with the tree is the wheels which are made up of nylon.
The machine is having a triangular shape, hinges are provided on each links for the movement of links with the variation in size of the tree.
Also, it is very easy to move from one place to another. There is a need to invent a machine to address treee efficiency and safety. But they are not successful as the input for them is muscular power of the labour and it requires a person to physically climb the tree to cut the crop trer harvest the nuts. When a rope attached to the machine is pulled from the ground; the machine climbs on the tree.
Now the motors for controlling the nozzle attachment is switched ON with the help of remote, then these motors start to rotate. It is the main source through which torque is generated. After reaching the ground the ground the setup is removed from the tree and attached to the next tree arexanut spraying.
