Description

Ploglegeme. Plow body.

Denne oppfinnelse vedrbrer et ploglegeme av fortrinnsvis ■ den art som innbefatter et skjær, veltefjel og landside. This invention relates to a plow body of the type preferably ■ which includes a cutting, rolling rock and land side.

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. The purpose of the present invention is to provide a plow body, which enables significantly improved steering as well as reduced necessary traction at the same time as increased effective cutting width while retaining the previously used tipper.

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. The new plow body is mainly characterized by the fact that it is equipped with a completed coulter, which in the plow body's position of use is substantially at the same height as the cutting tip but at some distance behind this, which projects from the land side of the plow body under and possibly somewhat past the overturning blade, mainly in the transverse direction of the plow body.

En hensiktsmessig utfbrelsesform av oppfinnelsen skal nedenfor beskrives under henvisning til den skjematiske tegning, på A suitable embodiment of the invention will be described below with reference to the schematic drawing, on

hvilken fig. 1 viser det nye ploglegeme i sideriss sett fra skjær-which fig. 1 shows the new plow body in side view seen from the

siden og fig. 2 sett ovenfra.page and fig. 2 views from above.

Det på tegningen viste ploglegeme er.utformet med et avThe plow body shown in the drawing is designed with one of

en skjærspiss 1 og et skjær 2 formet plogskjær som er stivt for-a cutting tip 1 and a cutting edge 2 in the form of a plow blade which is rigidly

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- bound with a tipping stone designated 3, which in the embodiment shown is provided with a covering 4. Furthermore, the plow body includes a land side 5, where, as can be seen more clearly from fig. 2 forms the attachment for a spiral spring 6. The inner end of the spiral spring 6 is rigidly connected to the upper end of a vertical shaft 7>whose lower end is rigidly connected with a substantial radial in the direction from the land side 5 out-

tering kan svinges i horisontalplanet mot virkningen av fjæren 6.tering can be swung in the horizontal plane against the action of the spring 6.

Ved anordningen av et kompletterende skjær 8 ifblge oppfinnelsen tilveiebringes en vesentlig bredere plogfure, hvilket på By arranging a complementary coulter 8 according to the invention, a significantly wider plow furrow is provided, which on

kjent måte også kan oppnåes ved utforming av skjæret 2, som i fig.known way can also be achieved by designing the cutting edge 2, as in 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- 2 indicated by the dashed line 2a, whereby, however, in the latter case significant disadvantages arise. It has thus been shown by tests that with a plow body designed in accordance with the invention only a part of the traction force is required, which would be necessary when using

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 by using the complementary coulter 8, a significantly improved maneuverability of the plow body is achieved when it is inserted or taken up of the soil. By the spring suspension of the cutting 8

kommer ploglegemet videre til automatisk å tilpasse seg til rådende jordforhold, hvorved plbyningen kan fori ope på en smidigere måte. the plow body also automatically adapts to the prevailing soil conditions, whereby the plow can be plowed in a more flexible manner.

Claims
