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

Now the motors for controlling the nozzle attachment is switched ON with the help of remote, then these motors start to rotate. The design and fabrication of arecanut tree climbing and spraying machine is presented in this paper.

Design and Fabrication of Arecanut Tree Climbing and Spraying Machine

The setup is connected across the climbee with the help of a brake cable. Selection of the Wheel Average Change in circumference of the tree is taken as climebr to 50cm. Skilled arecanut tree climbers have become scarce and farmers are finding it difficult to harvest the nuts. Line diagram to calculate Length of the links Figure 2. So development of a unique tree climbing mechanism is necessary which may be used for maintaining and harvesting applications.

One crop that has been most affected by this is the arecanut.

Areca Nut Tree Climber, Model No.: ATC

Driving wheels are machined from nylon rods having diameter coimber mm which is used to provide firm grip and also to operate the machine so that it climbs the tree easily. Then the wiper pump motor is switched ON. Wheels In this machine three driving wheels are used. It is mandatory to climb the trees a minimum of five times a year for a successful harvest – twice for the preventive spray against fungal disease, and thrice to harvest the arecanut.

The machine developed consists of a base frame with 3 nylon wheels driven by arrecanut high torque geared motor. Climbing Mechanism and Working 3.

It requires skill to climb arecanut tree. It is the heart of the setup. There is a need to invent a machine to address both efficiency and safety. In this study, considering all the above parameters, a safe, reliable and efficient climbing and spraying machine is designed and fabricated. The machine should grab the tree firmly to maintain its positions during the operation. The project is financially supported by the Vision Group of Technology, Karnataka government, and the management of Sahyadri College.

Many trees like coconut tree, arecanut tree, and palm trees are so tall that climbing them becomes risky. The machine can be fitted with pesticide spraying unit or nut plucking tool.

They have to climb the trees using muscle power. Cutting aecanut the areca nut bunch is also easy with a special type knife of this machine. After reaching the ground the ground the setup is removed from the tree and attached to the next tree for spraying.


The remote is used to control the motor. Nozzle Motor and Pump Nozzle motor is used to control the nozzle attachment for spraying purpose. H S Posted date: The pesticide is being transported from the tank to the nozzle with the help of plastic tubes. It has a robo cutter fixed to it and can be used to spray pesticides.

There arwcanut much equipment machines in the market to help the farmers in this regard. When the drive motor is switched on, the motor rotates the shaft which in turn rotates the wheels.

Windshield washer pump is used for spraying the pesticide which is stored in the tank to the crop. Therefore, maintaining sufficient friction force capable of handling the self-weight, maintaining the stability of the structure while in motion, reducing the total weight, arecaanut achieving the precise gripping are the important parameters that have to be considered.

In other case, machine used requires long fixing time to attach the machine to the tree and it has certain limitations. Introduction Researchers all around the world work on developing climbing machines, most of these climbing machines cljmber capable of climbing regular structures like poles, walls etc.
