Implement for Seed Sowing

Tyne

Tyne is a simple implement used for lining the field.It is a metal implement.It has a long handle and upper portion is curved.Seeds are sown according to the line.

The  drum seeder is for direct seeding of rice. Reduces planting costs of seeds and manpower. Improves harvests.
The use of  Drum Seeder leads to better crop management and higher harvest yield.  Immediate savings is realized on the quantity of seeds planted with the drum  seeder compared with hand broadcasting method.  Actual field uses show a savings of at least 120 kgs seeds per hectare.  Another immediate benefit is the increase in palay harvest of 10% due to the proper distribution of planting seeds resulting in optimized plant spacing for maximum use of sunlight and soil nutrients. The Rice Drum Seeder applies straight row seeding and controlled seeding rates from perforations along the circumference of the plastic drum seeder.  Cost of labor for seeding and planting is also reduced since the drum seeder is lightweight, simple to assemble and operated by one person.  The drum seeder, wheels and bushings are made of food grade virgin polyethylene plastic resin compounded with U.V. Stabilizers for use in tropical climates.    The Rice seeder is suitable for BOTH inbred or hybrid rice varieties.  It also comes with optional accessories to directly seed narrow or irregular shaped rice fields.

 Seed drill mechine



Drilling is the term used for the mechanized sowing of an agricultural crop. Traditionally, a seed drill consists of a hopper of seeds arranged above a series of tubes that can be set at selected distances from each other to allow optimum growth of the resulting plants. Seed is metered using fluted paddles which rotate using a geared drive from one of the drill's land wheels - seed rate is altered by changing gear ratios. Most modern drills use air to convey seed in plastic tubes from the seed hopper to the coulters - it is an arrangement which allows seed drills to be much wider than the seed hopper - as much as 12m wide in some cases. The seed is metered mechanically into an airstream created by a hydraulically powered on-board fan and conveyed initially to a distribution head which sub-devides the seed into the pipes taking the seed to the individual coulters.
The seed drill allows farmers to sow seeds in well-spaced rows at specific depths at a specific seed rate; each tube creates a hole of a specific depth, drops in one or more seeds, and covers it over. This invention gave farmers much greater control over the depth that the seed was planted and the ability to cover the seeds without back-tracking. This greater control meant that seeds germinated consistently and in good soil. The result was an increased rate of germination, and a much-improved crop yield (up to eight times 
A further important consideration was weed control. Broadcast seeding results in a random array of growing crops, making it difficult to control weeds using any method other than hand weeding. A field planted using a seed drill is much more uniform, typically in rows, allowing weeding with the hoe during the course of the growing season. Weeding by hand is laborious and poor weeding limits yield.
