Automatic Apparatus for Pouring Soil, Seed and Preparing Rice Seedling Trays


The automatic apparatus for preparing rice seedling trays has been designed and manufactured with the aim of replacing hard traditional nursery making procedures with a new technique applicable for rice, tomato, eggplant, sugar beet, ornamental flowers, etc. Using the apparatus allows optimum exploitation of water and avoidance of encountering plants to low temperature stress through transition of trays into greenhouses and eliminating spatial and temporal limitations in traditional methods.

Some of the most important characteristics and advantages of this apparatus are:

  1. increased crop yield and production
  2. decreased labor expenses
  3. lower seed consumption
  4. decreased time for preparing seedling trays (about 700 trays per hour)
  5. saving in water resources
  6. uniformity of seedlings and resulted mature plants
  7. increased area of mechanized cultivation
  8. higher precision in planting
  9. allowing second cropping in temperate climates
  10. ease of changing the parts and elimination of unnecessary components resulting in low complexity of the apparatus
  11. ease of transporting
  12. high tolerance of components against moisture and rust
  13. applicable of working by either electric generator or tractor P.T.O shaft according to client's order
  14. highly compatible with ordinary equipment of traditional farmers and possible to easily disassemble and reassemble by the farmers
  15. applicable to other nursery crops including tomato, eggplant, sugar beet, etc.
  16. equipped with automatic fuse to turn off the apparatus in the case of electric shock or mechanical stress to gear box and other parts
