Summary

            The traditional way of seed sowing consumes
more time and requires huge amount of
manpower, to reduce the soreness caused, the implanting tools were introduced.
An implanter is a tool which is used for sowing seeds and planting crops which
is operated by means of mechanisms. The implanter which is at present has a
drawback of depositing the crops one by one and which has to be done manually.

           To overcome the
difficulty of dropping the crops separately, a detailed research was made to
fix the problem. By introducing lining up mechanism in a plate, a certain number of seeds or crops are stored in
that plate which can be supplied to the implanter furtherly. The power is
generated from the rotation of wheels which is transferred through the bevel
gears and finally to the plate. The plate gets rotated and the crop is pushed
outside the plate one by one and dropped into the implanter, by means of
mechanisms. The lining up mechanism helps in guiding the crops to the
implanter.

2.      Project Description:

Introduction:

         
More than half of India’s population is dependent on agriculture either
directly or indirectly. The farming involves in multiples stages in order to
harvest and obtain a crop. Some of the steps in harvesting a crop are seed
implanting, spraying, weeding etc. The farmers should get updated with the
modern technology in order to make the most use
of the technology and yield more amount of crops.

              The equipment has been developed in such a way that it should meet the food
requirements of growing population and developing
industrialization. So the machines have
to be discovered that can help the farmers to save their time, money and
increase the production rate. Here usually most of the farmers implant the
crops manually which involves larger use manpower and more time-consuming. This problem is overcome with an
implanter is a tool considered to be used for seedling
or implanting a crop. In General, implanters are manually operated by making an impact with surface
of the agricultural field as shown in Fig. 1

 Objective

·        
Time for implanting the seeds is
minimized.

·        
Implanting the two seeds and planting
simultaneously.

·        
This prototype is operated only by
mechanical operations and not to be motorized.

·        
Reduced manpower for implanting.

Relevant works reported
in literature

·        
Pranil V. Savalakhe, Amit wandhre, Ashish Sontakke,Bhushan Patil1 stated that solar power sowing machine is basically works
on vertical discontinuous principle which
refers to the vertical movement which can be followed by an individual body in
an agricultural field and implements its discontinuous action in relation to
the horizontal line of work.

·        
Kyada 
A. R, patel D. B2 stated that as
the seed implanting machine is pushed, wheel
is rotating which transmit power to plunger through chain and sprocket
mechanism. Now the cam is mounted on sprocket shift which pushes plunger towards downward direction. Once plunger
is penetrated in soil and during the
backward stoke flapper is opened so seed gets separated from plunger and inserted in the dig.

·        
Nagesh B. Adalinge,
Ganesh B. Lavate, Ragul R. Mane3 stated that the equipment is push forward by using handles. Improved
seed-cum-seed drills are provided with seed and seed boxes, metering mechanism,
forrow openers, covering devices, frame,
ground drive system and control for variation of seed and seed rates.

·        
Ms. Trupti A. Shinde, Dr. Jeyashree. S.
Awati4 stated that In each complete rotation of rotating Wheel there is seeds falls from this seed drum and seed
plantation process taken place smoothly and without wastage of seeds. The
sowing disc is rotate in the seed
chamber, the seeds are falls in the seed chamber through seed storage tank .The seed buckets are collect the seeds
from the chamber and it sow in the ground
as required depth with the help of plough.

·        
Pradeep Gorre, Deepan Leburu, Srinivas
Kopparthi, Navakishore Kayala5 stated
that this project is to drive an external dc servo motor for which the drill equipment and seed sowing equipment is
connected. Here, the motion of the robot is decided by using a black line and
the seed sowing equipment works at every successive node on the black
line. 

·        
Prof. Abhijit G. Naik,
Prof. Amay Deorao Meshram, Prof. Siraj Y. sayyad6 stated that the prototype
is worked based on seed metering mechanism deliver
the seeds into the seed tube. . The feed
roller and the feed cut-off device are mounted
a shaft, running through the feed cups. The fluted rollers which are mounted at
the bottom of the seed box, receive seeds into longitudinal grooves and pass on
to the seed tube through the holes provided for this purpose. By shifting the
fluted wheel sideways, the length of the grooves exposed to the seed can be
increased or decreased and hence the amount of seed is controlled.

Overall
Summary

               The above literature clearly shows that seed implanting is done by the means of metering mechanism, solar power or motorized.
Hence this project is based on designing and developing a new seedling tool

Mechanism used in
implanter

              In
seedling implantation, it consists of an
implanting tool to dig and to implant the crop into the soil. In the
vehicle, it has two implanter and those two operated by means of the single
sliding mechanism. The mechanism is used in the vehicle, and lever 1is operates
the flapper that opens to plant the onion. Lever 2 used as brake.

Sliding crank mechanism

 

         The main operation takes place in the
mechanism is the conversion of rotating motion to reciprocating motion. The utilization
of the mechanism in this project is that the mechanism assists in digging the implanting tool.

 

Lining up mechanism       

 

              The power for the mechanism is
obtained from the rotation of wheel. Initially, the power is transmitted to bevel
gear from rotating wheel, the bevel gear converts the power to 90°, thus the
required power is obtained and lining up mechanism is done. It is used to
rotate and move the potato or onion into the implanting tool on a particular
timing.

exceptional influence in agriculture.  By
using this project one can spare less time for seed implanting and additionally
reduces a lot of labor cost. It is very much useful for small-scale farmers.

                      The maximum stress value
of vehicle frame is found out to be  
185.68

2 in ANSYS which is less than the yield
stress value and the design is said to be safe. Further the project is
processed to fabrication from analysis after knowing that the project design is
safe.

Scope of the project
