Abstract

On the periphery of the support unit (3) are several equally spaced brushes (1,2). Each brush is rigidily fixed to the support unit at its upper end, and projects freely outwards towards the ground surface. The brushes are formed of strong steel wire (9) enclosed in a steel wire-reinforced rubber casing (10). At their lower end, the steel wires extend out of the rubber casing to an extent the length of which corresponds to the depth of intended penetration into the earth surface.

Description

15 20 25 30 35 451 607 rustningsdetaljer visat sig utgöra sådana hinder, som i prakti- ken omöjli9qj0rt användning av maskindrivna jordfräsar eller jordbearbetningsmaskiner. 15 20 25 30 35 451 607 armor parts have been found to constitute obstacles which in practice make it impossible to use machine-driven cultivators or tillage machines.

Föreliggande uppfinning har till ändamål att åstadkomma en motordriven borstanordning som väl lämpar sig för avlägsnande av ogräs och/eller annan icke önskvärd växlighet på markavsnitt av varierande beskaffenhet och vars borstorgan är tillräckligt styva för att åstadkomma en tillfredsställande inträngning i markytan vid användning av borstanordningen, men som är till- räckligt eftergivliga för att ej orsaka skador på eller själva bli skadade av i markytan befintliga konstruktionselement, fun- damentdetaljer e dyl, och som sålunda lämpar sig särskilt väl för användning vid avlägsnande av växtlighet på järnvägsbanval- lar.The present invention has for its object to provide a motor-driven brush device which is well suited for the removal of weeds and / or other undesirable variability on soil sections of varying nature and whose brush means are sufficiently rigid to effect a satisfactory penetration into the ground surface when using the brush device, but which are sufficiently resilient so as not to cause damage to or themselves be damaged by construction elements present in the ground surface, foundation details, etc., and which are thus particularly well suited for use in removing vegetation on railway embankments.

Ett annat ändamål med uppfinningen är att åstadkomma en borstanordning med de nämnda egenskaperna, som är enkel till sin uppbyggnad och till följd därav är relativt billig i fram- ställning och som är enkel ur hanteringssynpunkt.Another object of the invention is to provide a brush device with the mentioned properties, which is simple in its construction and consequently is relatively inexpensive to manufacture and which is simple from a handling point of view.

Ett ytterligare ändamål med uppfinningen är att åstadkomma en borstanordning vid vilken de enskilda borstorganen på ett enkelt sätt kan utbytas och där borstorganens längd kan juste- ras.A further object of the invention is to provide a brush device in which the individual brush members can be replaced in a simple manner and where the length of the brush members can be adjusted.

Ovan angivna ändamål uppnås enligt uppfinningen genom ett utförande i enlighet med de särdrag, som angives i efterföljan- de patentkrav.The above objects are achieved according to the invention by an embodiment in accordance with the features stated in the following claims.

Uppfinningen beskrives i det följande i anslutning till ett utföringsexempel under hänvisning till bifogade ritningar, på vilka FIG l visar ett vertikalsnitt genom en borstanordning i enlighet med uppfinningen, FIG 2 visar en planvy av borstanordningen enligt uppfin- ningen monterad på en bärplatta, som i figuren visas delvis bortskuren, och FIG 3 visar en detalj av borstanordningens infästning till bärplattan.The invention is described in the following in connection with an exemplary embodiment with reference to the accompanying drawings, in which Fig. 1 shows a vertical section through a brush device in accordance with the invention, Fig. 2 shows a plan view of the brush device according to the invention mounted on a support plate, as in fig. is partially cut away, and FIG. 3 shows a detail of the attachment of the brush device to the support plate.

RÅ 10 15 20 25 30 451 6,07 Den i figurerna visade borstanordningen består av ett an- fta1 borstorgan 1, 2 samt en bäranordning 3, på vi1ken borstor- ganen är infästa, fritt utskjutande från bäranordningen i rikt- ning mot markytan. Bäranordningen består av en cy1indrisk hy1sa 4 med från denna radie11t utskjutande vingar 5, vid vars ytter- partier borstorganen 1, 2 är infästa. Varje vinge 5 uppbär så- 1unda vid sin ytterände två borstorgan 1, 2, vart och ett an- ordnat i en hå11are 6 med U-formigt tvärsnitt. Hå11arna 6 är företrädesvis genom svetsning infästa para11e11t med och inti11 varandra vid det yttre partiet av varje vinge. De U-formiga hå11arnas 6 fria skänk1ar har en höjd, som är mindre än borst- organens ytterdiameter, så att borstorganen 1, 2 mede1st en bricka 7, som sträcker sig para11e11t med vingen 5 tvärs borst- organen och på vardera sidan om hå11arna 6 är försedd med hål för skruvar 8, hå11es 1ösbart fastspänd mot vingen 5 för fast- k1ämning av vartdera borstorganet i respektive hå11are 6.RÅ 10 15 20 25 30 451 6.07 The brush device shown in the figures consists of an anterior brush member 1, 2 and a support device 3, to which the brush members are attached, projecting freely from the support device in the direction of the ground surface. The support device consists of a cylindrical sleeve 4 with wings 5 projecting from this radius, to the outer portions of which the brush members 1, 2 are attached. Each wing 5 thus carries at its outer end two brush members 1, 2, each arranged in a holder 6 with a U-shaped cross section. The holes 6 are preferably welded in parallel with and to each other at the outer portion of each wing by welding. The free legs of the U-shaped cavities 6 have a height which is smaller than the outer diameter of the brush members, so that the brush members 1, 2 have a washer 7, which extends parallel to the wing 5 across the brush members and on each side of the cavities 6. is provided with holes for screws 8, is releasably clamped against the wing 5 for securing each brush member in the respective holder 6.

Borstorganen 1, 2 består vartdera av en kraftig stå1vajer 9, över vi1ken är trädd en stå1trådsarmerad gummihy1sa 10. Vid borstorganets 1, 2 fria ände skjuter stå1vajern ut ur den stå1- trådsarmerade hy1san 10 ett stycke, vars 1ängd motsvarar borst- organets avsedda inträngningsdjup i marken. Den stå1trådsarme- rade gummihy1san 10 har ti11 uppgift att förhindra att vajern "tvinnas“ upp annat än vid den ur gummihy1san 10 fritt utskju- tande änden. Gummihy1san 10 har också ti11 uppgift att bibringa borstorganet sådana fjädrande egenskaper, att borstorganet er- hâ11er ti11räck1ig styvhet för att säkerstä11a det önskade in- trängningsdjupet i marken, samtidigt som borstorganets fjädran- de egenskaper förbättras ti11 förhindrande av skadegöre1se på i markskiktet befint1iga konstruktionseïement e11er fundamentde- ta1jer, t ex s1iprar, väx1ar o dy1. Efter hand som vajern för- s1ites vid den fria änden kan dess utskjutnings1ängd ur gummi- hy1san 10 justeras genom utdragning av vajern 9 ur gummihy1san i erforder1ig grad, varvid den stå1trådsarmerade gummihy1san avkapas vid sin övre ände i erforder1ig grad i samband med in- fästningen ti11 vingen 5 efter den utförda justeringen. 10 15 20 25 30 35 451 607 Den på ovan beskrivet sätt sammansatta borstanordningen infästes på undersidan av en cirku1är bärp1atta 11, som mede1st ett nav 12 uppbäres av en mede1st en drivmotor 13 roterbar axe1tapp 14. Infästningen av borstanordningen åstadkommes, så som särskiït framgår av FIG 3, medeist ett anta1 hakbuïtar 15.The brush members 1, 2 each consist of a strong steel wire 9, over which a steel wire-reinforced rubber sleeve 10 is threaded. At the free end of the brush member 1, 2, the steel wire protrudes from the steel-wire-reinforced sleeve 10 a piece whose length corresponds to the brush the ground. The steel wire-reinforced rubber housing 10 has the function of preventing the wire from being "twisted" other than at the end projecting freely from the rubber housing 10. The rubber housing 10 also has the function of imparting to the brush member such resilient properties that the brush member has a resilient member. in order to ensure the desired depth of penetration into the ground, at the same time as the resilient properties of the brush member are improved in order to prevent damage to structural elements present in the ground layer or foundation details, such as slips, grooves and dyes. the free end, its extension length from the rubber housing 10 can be adjusted by pulling the wire 9 out of the rubber housing to the required degree, the steel wire-reinforced rubber housing being cut off at its upper end to the required degree in connection with the attachment to the wing 5. The brush device assembled in the manner described above is attached to the underside a In a circular support plate 11, which is supported by means of a hub 12 by a shaft pin 14 rotatable by means of a drive motor 13. The attachment of the brush device is effected, as is particularly apparent from FIG. 3, with a number of hook bolts 15.

Hakbu1tarna griper om underkanten av vingarna 5 varvid inspän- ningen åstadkommes genom åtdragning av muttrar 16 mot översidan av bärp1attan 11.The hook bolts grip the lower edge of the wings 5, the clamping being effected by tightening nuts 16 towards the upper side of the support plate 11.

Den motordrivna borstanordningen en1igt uppfinningen kan t ex anbringas i änden på en kranarm, med vars hjä1p den rote- irande borstanordningen framföres över den markyta som ska11 be- hand1as, varvid borstanordningen mede1st kranarmen håïles på ett sådant avstånd i förhå11ande ti11 markytan, att det avsedda inträngningsdjupet erhå11es. För erhå11ande av optimaït resu1- tat bör borstanordningen 1ämp1igen instä11as med en viss mindre ïutning i framföringsriktningen. Vid av1ägsnande av icke önsk- värd växt1ighet från järnvägsbanva11ar, anordnas 1ämp1igen en borstanordning på vardera sidan om vardera rä1sen, varvid borstanordningarna uppbäres av ett rä1sgâende, sjä1vdrivet for- don.The motorized brush device according to the invention can for instance be placed at the end of a crane arm, with the aid of which the rotating brush device is advanced over the ground surface to be treated, the brush device being held at such a distance in relation to the ground surface that the intended the penetration depth is obtained11. In order to obtain an optimal result, the brush device should suitably be adjusted with a certain smaller inclination in the direction of travel. When removing unwanted vegetation from railway tracks, a brushing device is suitably provided on each side of each rail, the brushing devices being supported by a running, self-propelled vehicle.

Uppfinningen som ovan beskrivits i ans1utning ti11 ett på ritningarna visat utföringsexempe1 är icke begränsad därti11 utan kan varieras inom ramen för efterfö1jande patentkrav. Så- 1unda kan t ex borstorganens 1utning varieras ïiksom också an- ta1et borstorgan utan att den i patentkraven definierade upp- finningstanken frångås.The invention as described above in connection with an exemplary embodiment shown in the drawings is not limited thereto but can be varied within the scope of the appended claims. Thus, for example, the inclination of the brush members can be varied as well as the number of brush members without departing from the inventive concept defined in the claims.
