The invention relates to the field of agriculture, namely to the agricultural hand-operated technique for seeding crops on small plots.Hand seeder comprises a wheel (1) with two lateral covers, wherein is placed a cam (2 ) with profile on one section, rigidly fixed on an axle, mounted in the covers through bearings and connected to a pull rod handle. On the end surface of the wheel (1) are made through holes, in which are fixed grain tubes (3) with a lateral opening at the end from the inside of the wheel (1). The free end of the grain tubes (3) is made skewed, partially plugged. In each grain tube (3) is placed one pusher (4), one end of which slides on the surface of the cam (2), spring-loaded relative to the grain tube (3), and the opposite end is made with a protrusion. |
