Now the motors for controlling the nozzle attachment is switched ON with the help of remote, then these motors start to rotate. Remote control circuit Figure 4. The machine can be connected and detached from the wrecanut nut tree easily.

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!!

The design of the device has to be simple enough for villagers to operate, yet work efficiently to appeal to the majority. The machine can be fitted with pesticide spraying unit or nut plucking tool. The switch board is used to control the DC geared motors, windshield wiper pump, nozzle motors etc. It was observed that the maximum circumference of an arecanut tree is 50 cm and minimum circumference at the top is 30 cm. The contact friction between the wheel and tree is maintained with the help of tension springs and grippers on the wheels.

Driving wheels are machined from nylon rods having diameter of mm which is used to provide firm grip and also to operate the machine so that it climbs the tree easily.

With scarcity of labour, areca growers are finding it difficult to harvest their crop. 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.

Therefore, maintaining sufficient friction force capable of handling the self-weight, maintaining the stability of the structure while in motion, reducing the total weight, climbwr achieving the precise gripping are the important parameters that have to be considered. Guide way trer are rotated to the required position in order to spray pesticide to the crop.

The scope of this project is limited to climb arecanut trees having circumference between 30 and 50 cm. Sukesh K S Type of entry: But plucking areca nuts need no longer be an arduous task. The device has been tested for its performance and found safe, reliable, and efficient and also reduces the problems in climbing and spraying arecanut tree to a good extend.

Tree climbing machine, Arecanut, Spraying machine.

A spring is used to provide sufficient grip to the wheel on the tree according to the change in the size of the tree. So development of a unique tree climbing mechanism is necessary which may be used for maintaining and harvesting applications.

Areca Nut Tree Climber, Model No.: ATC, Rs /set, R Tech Engineering | ID:

For harvesting the nuts, and for spraying and applying insecticides on the crown, skilled labourers have to climb the tree manually. In recent years, labour scarcity has emerged as one of the foremost challenges in farming. We are currently working on to reduce the weight and with some alterations in the machine, we will be able to do it.

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. The remote is used to control the motor. Such a process looks easy, in reality it is a laborious and dangerous task. The frame of the arecanut tree climber can be opened up and held across the arecant. To help areca nut trse 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.

It provide the very essential torque for the setup to climb up and come down along the length of the tree. Then the wiper pump motor is switched ON. You must be logged in to post a comment.


In this study, considering all the above parameters, a safe, reliable and efficient climbing and spraying machine is designed and fabricated.

The machine can be used for spraying insecticides also.

The spraying is done in monsoon, while harvest time is typically in summer. DC geared motors having reduction gears which ensures self-locking of the tyres and thus maintains the arecsnut. The device consists of a triangular base frame which supports all the components to be built upon.

Areca nut tree climbing is a risky job that requires skilled labour.

Areca Nut Tree Climber, Model No.: ATC

Then the pesticide is being sprayed. Due to the friction between drive arrecanut and the bark of the tree machine rises up along the length of the tree. After which the pump is stopped, the whole setup is being brought back by changing the polarity of the switch so that the drive motor rotates in opposite direction there by making the wheels rotate in opposite direction.

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. Selection of the Wheel Atecanut Change in circumference of the tree is taken as 30cm to 50cm. Motors Five motors are used in this machine, in which 3 motors are used to drive the wheels, trwe 2 motors are used to controlling the nozzle attachment for spraying pesticides.

Under the guidance of Prof Abdul Kareem. It also requires afecanut agility and high manoeuvrability to be used as a product. The machine should grab the tree firmly to maintain its positions during the operation. When the drive motor is switched on, the motor rotates the shaft which in turn rotates the wheels.
