Line diagram to calculate Length of the links. An unskilled labour can also operate the machine safely and efficiently. The setup is connected across the tree with the help of a brake cable. With scarcity of labour, areca growers are finding it difficult to harvest their crop. Motors Five motors are used in climer machine, in which 3 motors are used to drive the wheels, other 2 motors are used to controlling the nozzle attachment for spraying pesticides. arecznut

It has a robo cutter fixed to it and can be used to spray pesticides. The machine developed consists of a base frame with 3 nylon wheels driven by 3 high torque geared motor.

Climbfr diagram to calculate Length of the links Figure 2. Then the pesticide is being sprayed. Arecanut climbing and spraying machine 3. The switch board is used to control the DC geared motors, windshield wiper pump, nozzle motors etc.

Also, it is very easy to move from one place to another. It is the main source through which torque is generated.

As this involves real hard, physical exertion, younger generations of labourers are losing interest, with potentially harsh implications for arecanut cultivation. Power from the battery is supplied to the motors using flexible wires and DPDT Double Pole Double Throw switch is used to control the movement of climbing machine as well as spraying unit. The nozzle is positioned near the arecanut with the help of guide way motors and then the guide way motors are switched OFF.

Areca nuts are collected in a basket. Leave a Reply Cancel Reply You must be logged in to post a comment. Such a process looks easy, in reality it is a laborious clikber dangerous task. The design of the device has to be simple enough zrecanut villagers to operate, yet climbdr efficiently to appeal to the majority.


In this tree climbing machine power is obtained from 12V battery through which drive motors are energized. To accommodate for change in the 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. It provide the very essential torque for the setup to climb up and come down along the length of the tree.

To arecaut areca nut farmers reduce dependency on tree climbers Asheesh V Rao, S Siddharth, K Shrihari and Praveen K P Rao have developed the machine that can reach a height of about meters within a minute. Powered By Vritee Technologies. Arecanut arecwnut attain a height of about feet.

Climbing Mechanism and Zrecanut The arecanut tree climbing and spraying machine works on the basic principle of friction that arecannut the relative lateral motion of two solid surfaces in contact.

The geared motor should be powerful enough to carry the payloads and weight of the machine. The frame of the arecanut tree climber can be opened up and held across the tree. It is mandatory to climb the trees climbfr minimum of five times a year for a successful harvest – twice for the preventive spray against fungal disease, tfee thrice to harvest the arecanut. When the drive motor is switched on, the motor rotates the shaft which in turn rotates the wheels.

In other case, machine used requires long fixing time to attach the machine to the tree and it has certain limitations. Nozzle Motor and Pump Nozzle motor is used to control the nozzle attachment for spraying purpose. It was observed that the maximum circumference of an arecanut tree is 50 cm and minimum circumference at the top is 30 cm.

Previous House in Karnataka, toilet in Kerala! August 30, We are currently working on to reduce the weight and with some alterations in the machine, we will be able to do it. Torque Calculation Calculating motor torque, 4.


At present, the machine weighs about six kg. But a very few are capable of climbing trees, main reason being irregular surface and variation of diameter with length []. It requires skill to climb arecanut tree.

The machine can be used for spraying insecticides also.

A specially designed remote controlled spraying unit is mounted on the frame. Windshield washer pump is used for spraying the pesticide which is stored in the tank to the crop. Now the motors for controlling the nozzle attachment is switched ON with the help of remote, then these motors start to rotate. The machine should grab the tree firmly to maintain its positions during the operation. The tension maintained by the spring must be good enough to maintain the gripping force between the wheel and the tree.

Areca Nut Tree Climber, Model No.: ATC

The tension of the spring helps to retain the machine at the required height. The design and fabrication of arecanut tree climbing and spraying machine is presented in this paper. The machine can be connected and detached from the areca nut tree easily.

Hence harvesting fruits and nuts and maintaining them becomes difficult. The specification of nozzle motor is listed below. Remote Control Unit 5.

Also the bark of some trees may not be strong enough to bear the weight of the climbing device, hence conventional climbing machine cannot be used for tree climbing applications []. In recent years, labour scarcity has emerged as one of the foremost challenges in farming. Students of Sahyadri College of Eng develop a low-cost areca nut tree climbing machine!!
