Abstract
Pneumatska kukuruzna sijaĉica koristi se u sjetvi kukuruza i drugih okopavina, sa ciljem polaganja sjemena na odreĊen razmak u redu i sjetva sjemena na konaĉan sklop. Sijaĉice smo podijelili u dvije osnovne skupine, i to prema vrsti i smjeru zraĉne struje koja djeluje na sjeme prilikom sjetve na pneumatske kukuruzne sijaĉice sa podtlakom i sijaĉice sa nadtlakom. Ove dvije skupine imaju zajedniĉke noseće i prijenosne radne elemente. Razlike se odnose na konstrukciju ventilatora i smjer strujanja zraka kao i izvedbu sjetvenih ureĊaja. U sjetvenom ureĊaju djelovanjem podtlaka na sjetvenu ploĉicu uzima zrno, otklanja višak zrna sa provrta, te se njenom rotacijom sije u tlo. Razmak je unaprijed odreĊen prijenosnim mehanizmom zadanim za odreĊenu kulturu. Kod sijaĉica sa nadtlakom zrak kroz mlaznicu otpuhuje višak zrna sa sjetvene ploĉice i prenosi ka ulagaĉu i tlu. Najnovija tehniĉka dostignuća nam ukazuju na povećanje kvalitete i uĉinka sjetve poboljšanjem, optimizacijom i kompjutorizacijom postojećih sustava. Eksperimentalno se uvode novi radni elementi uz kombinaciju sa već postojećim tehnološkim rješenjima. Konstrukcijom novih tipova sjetvenih ureĊaja dokazano povećavamo uĉinak i preciznost.
Abstract (english)
Pneumatic corn seeder is used for seed corn and other arable crops. Corn planters are divided in two groups, according to type and direction of air stream witch acts on corn seed during sowing maize on seeders with vacuum and seeders with pressure. These planters have equal supporting elements and gearboxes. Main difference between them are in radial fans and row unit. In vacuum planters radial fan makes air flow through pipes and make intake of seed inside row unit. The seed stick in hole on the seeder plate, clear other seeds from the hole and rotating in forward direction being relased from vacuum in to the soil. Planters with overpressure in row unit works different. The fan makes overpressure in the pipes and row unit, blow on seeder plate and the excess seeds being removed. New technological solutions demonstrate increase of precision and performance, while improving, optimize and electronically control operation of pneumatic corn planter. New design of row units confirmly proves accuracy between seeds, increase production and quality of sowing.
