Opfindelsen angår et apparat til opsnitning af pressede halmballer som angivet i krav l's indledning.The invention relates to an apparatus for slicing pressed straw bales as set forth in the preamble of claim 1.

Formålet med opfindelsen er at anvise et apparat, som frembringer et snittet halmmateriale med en fin, let 5 og luftig konsistens, især med en strålængde på 5-10 cm.The object of the invention is to provide an apparatus which produces a cut straw material with a fine, light and airy consistency, especially with a beam length of 5-10 cm.

Fra engelsk patentskrift nr. 2.142.222 kendes et noget beslægtet apparat, hvor knivene bevæger sig både op og ned inde i halmballen. Herved fås imidlertid et uønsket flosset produkt, som ikke er let og luftigt.English patent specification No. 2,142,222 discloses a somewhat related apparatus in which the blades move both up and down inside the straw bale. However, this results in an undesirable frayed product which is not light and airy.

10 Fra dansk patentskrift nr. 139.051 kendes et ligele des noget beslægtet apparat med modholdsorganer, men dette har ikke vist sig i stand til at give en meget let og luf- f tig halm. Dette opnås imidlertid med apparatet ifølge opfindelsen, som er ejendommeligt ved den i krav l's kende-15 tegnende del anførte konstruktion.10 From Danish Patent Specification No. 139,051, a similar device similar to the restraining means is known, but this has not proved capable of providing a very light and airy straw. However, this is achieved with the apparatus according to the invention, which is peculiar to the construction according to the characterizing part of claim 1.

Forsøg har godtgjort, at det omhandlede apparat frembringer den ønskede konsistens af halmen.Experiments have shown that the apparatus in question produces the desired consistency of the straw.

En særlig hensigtsmæssig udførelsesform for apparatet ifølge opfindelsen udmærker sig ved, at de bevægelige 20 knivarme og modholdsorganerne hver er monteret i to praktisk taget identiske sæt, som skiftevis føres ind i og ud af halmen.A particularly convenient embodiment of the apparatus according to the invention is characterized in that the movable knife arms and the restraining means are each mounted in two practically identical sets which are alternately inserted into and out of the straw.

Ligeledes har det ifølge opfindelsen vist sig særlig fordelagtigt, at man benytter to krumtapsæt, som giver de 25 to sæt knivarme en tilnærmet lodret bevægelse og de to sæt modholdsorganer en tilnærmet vandret bevægelse. Imidlertid kan hele systemet drejes en vilkårlig vinkel mel- t lem 0 og 90° i forhold til denne foretrukne stilling.Also, according to the invention, it has been found particularly advantageous to use two crank sets which give the two sets of knife arms an approximately vertical movement and the two sets of restraining means an approximately horizontal movement. However, the entire system can be rotated at any angle between 0 and 90 ° relative to this preferred position.

En simpel udførelsesform til opnåelse af den ønskede 30 bevægelse af apparatets bevægelige dele omfatter en krumtapmekanisme med styreskiver og styreknaster, som frembringer en bevægelse som en smal lodret ellipse svarende til med tilnærmelse et smalt lodret rektangel.A simple embodiment for obtaining the desired movement of the moving parts of the apparatus comprises a crank mechanism with guide discs and control knobs which produces a movement as a narrow vertical ellipse corresponding to approximately a narrow vertical rectangle.

Opfindelsen skal forklares nærmere i forbindelse 35 med tegningen, hvorThe invention will be explained in more detail in connection with the drawing, wherein

- 2 - fig. 1 viser et stærkt skematiseret billede af apparatet ifølge opfindelsen i perspektiv, fig. 2 apparatets knivarme og modholdsorganer 5 med respektive bevægelsesdiagrammer samt apparatets modknive i perspektiv og i større målestok, fig. 3 samme dele i planbillede, og ’ fig· 4 en enkelthed i endnu større målestok 10 set fra siden.FIG. 1 is a perspective view of a highly schematic view of the apparatus of the invention; FIG. 2 shows the apparatus's knife arms and restraint means 5 with respective movement diagrams and the apparatus counter-knives in perspective and on a larger scale; FIG. 3 shows the same parts in plan view, and Fig. 4 shows a simplicity on an even larger scale 10 from the side.

Det på tegningen viste apparat omfatter på den ene side et bord T med ikke nærmere viste organer til fremføring af en halmballe S og med snitteapparatets stationære dele og på den anden en krumtapmekanisme K med en motor M, 15 som bærer snitteapparatets bevægelige dele.The apparatus shown in the drawing comprises, on the one hand, a table T with means not shown, for conveying a straw bale S and with the stationary parts of the cutter, and on the other a crank mechanism K with a motor M, which carries the moving parts of the cutter.

Disse bevægelige dele omfatter: 1) to sæt knivarme A og B med pladeformede knive F, som ved hjælp af krumtapmekanismen K drives i en ellipseformet bane med tilnærmet lighed med et smalt lodret rekt- 20 angel som antydet i fig. 2 ved hjælp af de indsatte bevægelsesdiagrammer A' og B', hvilket sikrer en nedadbevæ-gelse af knivarmene inde i halmballen, og 2) to sæt modholdsorganer C og D, som ved hjælp af krumtapmekanismen K med tilnærmelse føres retlinet frem 25 og tilbage vinkelret på knivarmene A og B. De antydede bevægelsesdiagrammer C og D' angiver, at modholdsorganerne C er længst fremme mod halmballen S og derefter vil bevæge sig bort fra denne (pilen mod venstre i diagrammet C i fig. 2), medens modholdsorganerne D er trukket 30 længst bort fra halmballen og derefter vil blive bevæget mod højre i fig. 2.These moving parts comprise: 1) two sets of knife arms A and B with plate-shaped blades F, which are driven by means of the crank mechanism K in an ellipse-shaped web approximately similar to a narrow vertical rectangle as indicated in FIG. 2 by means of the inserted movement diagrams A 'and B', which ensure a downward movement of the knife arms inside the straw bale, and 2) two sets of restraining means C and D, which by means of the crank mechanism K with approximation are moved rectilinearly 25 and back perpendicularly on the knife arms A and B. The indicated movement diagrams C and D 'indicate that the restraining means C are furthest towards the straw bale S and will then move away from it (the arrow to the left in the diagram C in Fig. 2) while the restraining means D are drawn. 30 farthest from the straw bale and will then be moved to the right in FIG. 2nd

Den indbyrdes stilling af knivarmene A og B og modholdsorganerne C og D i en given situation fremgår desuden af fig. 3.Furthermore, the position of the knife arms A and B and the restraining means C and D in a given situation is shown in FIG. Third

35 Det er illustreret i fig. 3, at de nederste bevæge lige knive F kan være dobbelte, og modholdsknivene D da enkelte (til venstre i figuren), eller at omvendt de nederste bevægelige knive F kan være enkelte, og modknivene DK 1531138 - 3 - E da dobbelte (til højre i figuren). Den til venstre i figuren viste udførelsesform har vist sig at være bedst og foretrækkes derfor.35 It is illustrated in FIG. 3, that the lower moving straight blades F can be double, and the holding knives D then single (on the left in the figure), or that conversely the lower moving knives F can be single, and the counter knives DK 1531138 - 3 - E then double (on the right in the figure). The embodiment shown on the left in the figure has proven to be best and is therefore preferred.

I fig. 4 ses til højre de stationære dele af appara-5 tet anbragt på bordet T. Det består af et antal modknive E, som de nederste to af de pladeformede knive F passerer imellem under driften.In FIG. 4 is shown on the right the stationary parts of the apparatus placed on the table T. It consists of a number of counter blades E which the lower two of the plate-shaped blades F pass between during operation.

Modknivene E er monteret ved hjælp af fjedre, så at de kan undvige, hvis halmballen skulle indeholde en sten 10 eller andre hårde genstande.The counter blades E are mounted by means of springs, so that they can avoid if the straw ball should contain a stone 10 or other hard objects.

Knivarmene A og B er vist lodrette, men kan også tænkes monteret under en vilkårlig vinkel fra 0 til 90° i forhold til lodret, idet modholdsorganerne da er drejet en tilsvarende vinkel.The knife arms A and B are shown vertically, but may also be mounted at any angle from 0 to 90 ° with respect to the vertical, the restraining means being then turned a corresponding angle.

15 I stedet for to sæt knivarme A og B, som er anbragt 180° forskudt på en cirkel, kan man Også benytte f.eks. 4, 6 eller 8 sæt knive, som er henholdsvis 90, 60 og 45° indbyrdes forskudt.15 Instead of two sets of knife arms A and B, which are placed 180 ° offset on a circle, one can also use e.g. 4, 6 or 8 sets of knives which are displaced 90, 60 and 45 ° respectively.

Det vil umiddelbart forstås, at apparatet virker på 20 den måde, at når en halmballe S føres mod apparatets bevægelige dele (mod venstre i fig. 2), vil skiftevis knivarmene A og B med knivene F med lodrette nedadrettede bevægelser inde i halmballen skære halmen itu, medens sættene af modholdsorganer C og D, som skiftevis og i takt med 25 knivarmenes bevægelse føres ind i og ud af halmballen, vil forebygge, at halmen klumper. Herved opnås en meget ønskværdig konsistens af den snittede halm.It will be understood immediately that the apparatus acts in such a way that when a straw balloon S is directed toward the movable parts of the apparatus (to the left in Fig. 2), alternately the knife arms A and B with the blades F with vertical downward movement within the straw balloon will cut the straw. two, while the sets of restraining means C and D, which alternately and in step with the movement of the knife arms are inserted into and out of the straw balloon, will prevent the straw from clumping. This results in a very desirable consistency of the cut straw.
