Seed Dibbler
Project Description :

Agriculture is the backbone of our economy and still there is a lag in technical facilities for small land farmers. currently in india 156.24 million are small land farmers, which cultivates 80% of the total agriculture land. the cultivation cycle starts with the land preparation followed by sowing, application of manures and fertilizers, irrigation and completing cycle by harvesting. over the years farmers have developed various sowing practices which includes broad casting, line sowing, seed dropping behind the plough and dibbling. the majority of present sowing machines are dedicated towards large farmers which practices line sowing. thus, small farmers resort to either broad casting, seed dropping behind the plough or renting tractors for line sowing. for the former it is tedious and inefficient and for the later, it is costly. out of these sowing practices dibbling is the most efficient in terms of seed requirement, has better crop control with proper spacing and desired seed depth. though it has several advantages it is laborious and time intensive method and thus increasing cost of cultivation. so farmers prefer to use this method only when high value and bold seeds are to be sown. still farming community lacks the machine which can fully automate dibbling. we aim to make a seed dibbler which is efficacious for small farmers. the machine is light, compact, ergonomic, and easy to assemble. the machine has been divided into three systems consisting of drivetrain, dibble and seed meter. the farmer has to drive the machine which will rotate a wheel, part of drivetrain, it converts rotation of wheel into reciprocating motion of dibble. a bell crank is installed to act as a lever which reduces driving and plunging force. seed meter has been placed around the periphery of the dibble and close to ground so the farmer can precisely control seed dropping rate. machine has three wheels with independent rear wheels for easy maneuvering. use of ms channel as a chassis frame for a maximum durability. as farmer cultivate multiple crops over the year the seed dibbler has following modular specifications- seed depth up to 60 mm, consecutive seed gap ranges from 10 to 90 cm and seed meter can be modified according to seed shape and size. it’s a single man driven automated sowing dibbler and uses a discrete seed sowing mechanism which reduces the driving force and eradicate any wastage of seeds. this allows farmers to control the sowing area around the more intricate locations and eliminate any seed sowing at undesirable locations. as the rural india lacks 24 hour continuous electricity, we have avoided any use of electronics which further makes it weatherproof and robust. theoretical operating force of the machine is 80 newtons with the operating speed of 2km/h, the labor hour per hectare is reduced to 16 hours from 64 hours. to make it feasible for small farmers, machine has been designed considering mass production and assembly. thus anticipated upper limit cost of the prototype ₹ 2500. in addition to small scale farming machine can also be used for urban farming and on a bigger perspective, machine can be extended for big farmers by increasing number of dibblers in a row and tractor driven.
