Abstract

Sowing apparatus for automatically sowing seed after scarifying. The apparatus is intended in particular for sowing seeds from pine and spruce. The apparatus comprises a rotatable seed magazine 2 and an arrangement in the form of a hopper 3 for discharging seed from the magazine 2 down onto the ground. The rotatable seed magazine 2 is in the form of a cylindrical drum which rotates about its axis, the drum being provided with seed- discharge ducts 7 which extend in the direction of the chord from the inside of the drum to its outside. The hopper 3 is provided with inlets in the form of nozzles 13 for the supply of compressed air 14, 14' which prevents the seeds forming lumps in the hopper and the magazine. <IMAGE>

Description

7902057-4 ler nedsmutsade med jord inblåses luft i tratten 3 via mun- stycken 13 på sätt som antytts medelst pilarna 14 och l4'. 7902057-4 soiled with soil, air is blown into the funnel 3 via nozzles 13 in a manner indicated by arrows 14 and 14 '.

Såddapparaten innefattar även en indikeringslampa 15 som kan vara kopplad till en fotodetektor vid trattmynningen 12 och som lyser med fast sken när trumman 2 roterar och blin- kar varje gång ett frö faller ut genom mynningen 12, varvid lampan 15 slocknar om mynningen 12 av någon anledning blir tílltäppt.The seed apparatus also comprises an indicator lamp 15 which may be connected to a photodetector at the funnel mouth 12 and which lights up steadily when the drum 2 rotates and flashes each time a seed falls out through the mouth 12, the lamp 15 extinguishing around the mouth 12 for some reason gets clogged.
