Description

Ploglegeme.
Denne oppfinnelse vedrbrer et ploglegeme av fortrinnsvis ■ den art som innbefatter et skjær, veltefjel og landside.
Formålet med foreliggende oppfinnelse er å tilveiebringe et ploglegeme, som muliggjbr vesentlig forbedret styring samt mins-ket nbdvendig trekkraft samtidig med oket effektiv skjærbredde under bibehold av tidligere anvendt veltefjel.
Det nye ploglegeme kjennetegnes i hovedsaken ved, at det er forsynt med et i ploglegemets bruksstilling vesentlig i hbyde med skjærspissen men i noen avstand bak denne anordnet komplettert skjær, som fra ploglegemets landside rager inn under og eventuelt noe forbi veltefjelen hovedsakelig i ploglegemets tverretning.
En hensiktsmessig utfbrelsesform av oppfinnelsen skal nedenfor beskrives under henvisning til den skjematiske tegning, på
hvilken fig. 1 viser det nye ploglegeme i sideriss sett fra skjær-
siden og fig. 2 sett ovenfra.
Det på tegningen viste ploglegeme er.utformet med et av
en skjærspiss 1 og et skjær 2 formet plogskjær som er stivt for-
bundet med en med 3 betegnet veltefjel, som i den viste utfbrelse er forsynt med en forlegelse 4. Videre innbefatter ploglegemet en landside 5, der som tydeligere fremgår av fig. 2 utgjor feste for en spiralfjær 6. Spiralfjærens 6 indre ende er stivt forbundet med den ovre ende av en vertikal aksel 7> hvis nedre ende er stivt forbundet med et vesentlig radielt i retning fra landsiden 5 ut-
skytende knivbladformet kompletterende skjær 8, som ved sin mon-
tering kan svinges i horisontalplanet mot virkningen av fjæren 6.
Ved anordningen av et kompletterende skjær 8 ifblge oppfinnelsen tilveiebringes en vesentlig bredere plogfure, hvilket på
kjent måte også kan oppnåes ved utforming av skjæret 2, som i fig.
2 antydet med den stipplede linje 2a, hvorved dog i det sistnevnte tilfelle vesentlige ulemper oppstår. Det har således ved prover vist seg, at ved et ploglegeme utformet ifblge oppfinnelsen bare en del av den trekkraft kreves, som ville være nbdvendig ved anven-
delsen av et ploglegeme med et skjær ifblge linjen 2a. Videre opp-
nåes ved anvendelsen av det kompletterende skjær 8 en vesentlig forbedret manbvrering av ploglegemet ved dettes isetting respektiv opptaking av jorden. Ved den fjærende opphengning av skjæret 8
kommer ploglegemet videre til automatisk å tilpasse seg til rådende jordforhold, hvorved plbyningen kan fori ope på en smidigere måte.
