Certified that the project work entitled “Arecanut Tree Climber and Pesticide Sprayer” Two nozzles are placed on either side at the top of the machine with. Arecanut trees attain a height of about feet. It is mandatory Considering all the casualties in conventional tree climbing we decided to make a robot that. In this context, this project work presents “Areca nut Harvesting Machine.” Here we are designing and fabricating areca nut tree is.

The switch board is used to control the DC geared motors, windshield wiper pump, nozzle motors etc.

Skilled arecanut tree climbers have become scarce and farmers are finding it difficult to harvest the nuts. The tension of the spring helps to retain the machine at the required height. The design and fabrication of arecanut tree climbing arecanug spraying machine is presented in this paper. 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.

Areca Nut Tree Climber, Model No.: ATC

Cutting of the areca nut bunch is also easy with a special type knife of this machine. Windshield washer pump is used for spraying the pesticide which is stored in the tank to the crop. The tension maintained by the spring must be good enough to maintain the gripping force between the wheel and the tree. Only skilled labourers can arecajut out these farming operations.

One crop that has been most affected by this is the arecanut. Due to the friction between drive wheel and the bark of the tree machine rises up along the length of the climbijg. When the setup reaches on top of the tree the drive motor is switched OFF in the remote control unit.


But a very few are capable of climbing trees, main reason clikbing irregular surface and variation of diameter with length []. 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 frame of the arecanut tree climber can be opened up and held across the tree.

A specially designed remote controlled spraying unit is mounted on the frame. The DC motor used to drive wheel is square geared DC motor.

Nozzle Motor and Pump Nozzle motor is used to control the nozzle attachment for spraying purpose. There are much equipment machines in the market to help the farmers in this regard. Also, it is very easy to move from one place to another. In this study, considering all the above parameters, a safe, reliable and efficient climbing and spraying machine is designed and fabricated. Pulley and a brake cable is used to ensure smooth movement of the links.

DC geared motors having reduction gears which ensures self-locking of the tyres and thus maintains the height. Remote control circuit Figure 4.

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

Specifications aecanut Functions of Parts Used 4. 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.


When the drive motor arecankt switched on, the motor rotates the shaft which in turn rotates the wheels. The machine developed consists of a base frame with 3 nylon wheels driven by 3 high torque geared motor. Selection of the Wheel Average Change in circumference of the tree is taken as 30cm to 50cm. Length of Link Arecaanut 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.

In recent years, labour scarcity has emerged as one of the foremost challenges in farming. The machine can be connected and detached from the areca nut tree easily. Arecanut trees attain a height of about feet. Sukesh K S Type of entry: Line diagram to calculate Length of the links.

It requires skill to trfe arecanut tree. Wheels In this machine three driving wheels are used.

They have to climb the trees using muscle power. It provide the very areanut torque for the setup to climb up and come down along the length of the tree.

Remote Control Unit macchine. Arecanut climbing and spraying machine 3. 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. When a rope attached to the machine is pulled from the ground; the machine climbs on the tree.
