The nozzle is positioned near the arecanut with the help of guide way motors and then the guide way motors are switched OFF. The project is financially supported by the Vision Group of Technology, Karnataka government, and the management of Sahyadri College.

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. The spraying is done in monsoon, while harvest time is typically in summer. In recent years, labour scarcity has emerged as one of the foremost challenges in farming. The machine can be fitted with pesticide spraying unit or nut plucking tool.

The machine can be used for spraying insecticides also. To help 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. There are much equipment machines in the market to help the farmers in this regard.

Areca Nut Tree Climber, Model No.: ATC

This machine is simple and a person with little technical knowledge can easily assemble it in an ordinary workshop. Remote Control Unit 5. Then the pesticide is being sprayed. Only skilled labourers can carry out these farming operations.

Length of Link Length of each link is taken as 58 cm, the calculations are shows below and line diagram to calculate length of the links is shown in figure 1. It requires skill trfe climb arecanut tree. Many trees like coconut tree, arecanut tree, and palm trees are so tall that climbing them becomes risky. Now the motors for controlling the nozzle attachment is switched ON with the help of remote, then these motors start to rotate.


A spring is used to provide sufficient grip to the wheel on the tree according to the change in the size of the tree. arecanuf

So development of a unique tree climbing mechanism is necessary which may be used for maintaining and harvesting applications. 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.

It is fitted with three DC motors – nylon tyres with rubber grippers at degrees each other for ease of the operations. The specification of nozzle motor is listed below. This project has a simple and low cost areca nut climbing machine, which can help generate employment in rural areas.

An unskilled labour can also operate the machine safely and efficiently. This is the most suitable machine for harvesting areca nuts without man climbing on the tree.

Line diagram to calculate Length of the links. Pulley and a brake cable is used to ensure smooth movement of the links.

Areca nut tree climbing is a risky job that requires skilled labour. Climbing Mechanism and Working 3.

Design and Fabrication of Arecanut Tree Climbing and Spraying Machine

Previous House in Karnataka, toilet in Kerala! 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 are capable of climbing regular structures like poles, walls etc.

There is a need to invent a machine to address both efficiency and safety. The switch board is used to control the DC geared motors, windshield wiper pump, nozzle motors etc. 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.


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 [].

Areca Nut Tree Climber And Sprayer :: Create the Future Design Contest

But a very few are capable of climbing trees, main reason being irregular surface and variation of diameter with length []. The design and fabrication of arecanut tree climbing and spraying machine is presented in this paper.

Under the guidance of Prof Abdul Kareem. DC geared motors having reduction gears which ensures self-locking of the tyres and thus maintains the height. The geared motor should trfe powerful enough to carry the payloads and weight of the machine. Specifications are given below; Volt: After reaching the ground the ground the setup is removed from the tree and attached to the next tree for spraying.

At present, the machine weighs about six kg. The machine should be capable of adjusting to the varying cross-section of the tree during upward and downward movements.

Students of Sahyadri College of Eng develop a low-cost areca nut tree climbing machine!!

They have to climb the trees using muscle power. Windshield washer pump is used for spraying the pesticide which is stored in tree tank to the crop. Due to the friction between drive wheel and the bark of the tree machine rises climbet along the length of the tree.

This is a unique model which will be the machine-front of the areca nut industry and in turn will serve as a great help and boon to areca nut farmers.
