RESEARCH ON IMPROVING THE PLOWING QUALITY AND REDUCING THE FUEL CONSUMPTION IN THE WORK OF PLOWING AND SUBSEQUENT AGRICULTURAL WORK BY EDITING THE SHAPE BY MOLDBOARD

C-tin Arustei

Abstract
This work relates to a plough’s corps consisting of a mouldboard mounted on frame on which is still mounted the additional mouldboard . The semicircular chest of the mouldboard is provided with a self-sharpening blade on the semicircular side, the moulboard’s tail being composed of bands (strips). At the bottom of the mouldboard is mounted the plaz and plowshare which is provided with self-sharpening blade, and on the mouldboard tail’s bands are mounted knives of special shape by welding or with screws which are designed to cut and grind the share during work.
Is performed simultaneously and the strips strengthening, thus increasing their stability.
By modifying the self-sharpening blade of the mouldboard’s chest and plowshare is found as the resistance to advancement of mouldboard lowers, resulting fuel economy at the work of plowing and subsequent agricultural work.

Key words: mouldboard, mouldboard chest, mouldboard tail, bands (strips), plowshare, self-sharpening

Rezumat
Cercetarile efectuate se refera la o trupita pentru plug, formata dintr-o cormana montata pe o bârsa pe care se mai afla dispusa si o cormana suplimentara. Pieptul cormanei, de forma semicirculara, este prevazut cu ascutis cu autoascutire pe partea semicirculara iar coada cormanei este compusa din benzi (fâsii). La partea inferioara a cormanei se afla montat un plaz si brazdarul care este prevazut cu ascutisuri cu autoascutire iar pe benzile cozii cormanei se gasesc niste cutite de forma speciala, montate prin sudura sau cu suruburi ce au rolul de taiere si maruntire a brazdei în timpul lucrului.
Concomitent se realizeaza si o rigidizare a fâsiilor, crescând astfel stabilitatea lor. Prin modificarea ascutisurilor cu autoascutire de la pieptul cormanei si a brazdarului se constata ca scade rezistenta la înaintare a cormanei, realizându-se astfel o reducere a consumului de combustibil atât la lucrarile de aratura cât si la lucrarile agricole efectuate ulterioare.

Cuvinte cheie: cormana, piept cormana, coada cormana, benzi (fâsii), brazdar, autoascutire
