<p>A device for gel-coating seeds having a structure in which a gelling agent is filled into a nozzle, and seeds are charged into and held in the gelling agent to form gel-coated seeds which are then allowed to fall. A nozzle (98) into which a gelling agent and seeds are charged is provided to the nozzle case (70) (71) of a processing unit (2), an open/close rod (73) at a nozzle intermediate portion is slidably inserted into the upper portion of the nozzle case, an air chamber (70b), in which the piston (74a) of a compression pin (74) sliding interlockingly with the open/close rod (73) can reciprocate, is provided below the rod, the air chamber (70b) being allowed to communicate with the nozzle (98), the upper portion of the nozzle (98) is blocked with the open/close rod (73) after the gelling agent is filled in a drop hole (98b) in the lower portion of the nozzle and the seeds are charged, air is fed into the nozzle (98) by allowing the piston (74a) above the nozzle to slide, and gel-coated seed are discharged from the nozzle.</p> |
