Description
Feiemaskin. Sweeper.
Oppfinnelsen vedrører en feiemaskin med et hydraulisk drevet, styrbart fronthjul og et par frittløpende bakhjul og med roterbare gulvbørster foran fronthjulet. The invention relates to a sweeping machine with a hydraulically driven, steerable front wheel and a pair of free-running rear wheels and with rotatable floor brushes in front of the front wheel.
Med oppfinnelsen tar man sikte på å oppnå at feiemaskinen skal kunne ha en gulvskrape som kan bevege seg i forhold til børst-ene, selv om de er opphengt i samme bæreramme. Dette vil være en fordel, fordi børstene bearbeider en annen del av gulvet enn-skrapen, og ujevnheter vil på denne måten kunne opptas. With the invention, the aim is to achieve that the sweeper should be able to have a floor scraper that can move in relation to the brushes, even if they are suspended in the same support frame. This will be an advantage, because the brushes process a different part of the floor than the scraper, and unevenness will be able to be absorbed in this way.
Ifølge oppfinnelsen oppnås dette ved at den innledningsvis nevnte feiemaskin er forsynt med en bæreramme for gulvbørstene, hvil-ken bæreramme er svingbart opphengt om bakhjulsaksen.og kan svinges^, opp og ned med en hydraulisk drevet sylinder, og ved at en gulvskrape strekker seg delvis rundt gulvbørstene og er opphengt i bærerammen ved hjelp av et parallellogramoppheng. According to the invention, this is achieved by the sweeping machine mentioned at the outset being provided with a support frame for the floor brushes, which support frame is pivotably suspended on the rear wheel axis and can be swung up and down with a hydraulically driven cylinder, and by a floor scraper partially extending around the floor brushes and is suspended in the support frame using a parallelogram suspension.
Hensiktsmessig kan en hydraulisk drevet sylinder være opplagret i bærerammen for heving og senkning av gulvskrapen i forhold til bærerammen. Appropriately, a hydraulically driven cylinder can be stored in the support frame for raising and lowering the floor scraper in relation to the support frame.
Med oppfinnelsen oppnås at gulvflaten kan bevege seg i forhold til børstene og ujevnheter vil på denne måten opptas-. Ved at bærerammen er lagret om bakhjulsaksen oppnås en relativt stor avstand fra selve børste- og skrapeanordningen og svingepunktet for bærerammen, slik at svingebevegelsen som rammen og de tilhørende aggregater tilhører, blir tilnærmet vertikal. Dette gir bedre skrape- henholdsvis børsteeffekt. With the invention, it is achieved that the floor surface can move in relation to the brushes and unevenness will in this way be absorbed. As the carrier frame is stored around the rear wheel axis, a relatively large distance is achieved from the brush and scraper device itself and the pivot point for the carrier frame, so that the pivoting movement to which the frame and the associated aggregates belong, becomes approximately vertical. This gives a better scraping or brushing effect.
Oppfinnelsen skal forklares nærmere med henvisning til teg-ningene hvor The invention shall be explained in more detail with reference to the drawings where

Maskinen som er vist i fig. 1 og 5 er rammeløs og består av flere sammensatte deler. Feiemaskinen innbefatter en beholder 11 til hvis ene ende det er fastsveiset en vertikal instrumentsøyle 12. Et hjulrom 13 er sveiset til den andre endeveggen av beholderen- 11 og danner sammen med beholderen en understøttelse for et batterirom 15 og en beholder 16. For fastgjøring av batterirommet 15 benyttes det egnede festeanordninger 14. The machine shown in fig. 1 and 5 are frameless and consist of several composite parts. The sweeper includes a container 11 to one end of which a vertical instrument column 12 is welded. A wheel space 13 is welded to the other end wall of the container 11 and together with the container forms a support for a battery compartment 15 and a container 16. For fixing the battery compartment 15, suitable fastening devices 14 are used.
En aksel 17 strekker seg gjennom hjulrommet 13 og bærer An axle 17 extends through the wheel space 13 and carries
fritt dreibare bakhjul 18. freely rotating rear wheels 18.
I instrumentsøylen 12 er det en bæreplate 19 som gjennom-trenges av en bøssing 20. I bøssingen 20 er det opplagret en bærer-og styrestang 21 for det hydraulisk drevne, styrbare forhjul 25. Som vist i fig. 4 er styrestangen 21 forbundet med en L-formet hjulbrakett 23. Denne brakett 23 bærer et hjullager 24 hvori den ikke viste aksel til forhjulet 25 er opplagret. In the instrument column 12, there is a support plate 19 which is penetrated by a bushing 20. In the bushing 20, a support and control rod 21 for the hydraulically driven, steerable front wheel 25 is stored. As shown in fig. 4, the control rod 21 is connected to an L-shaped wheel bracket 23. This bracket 23 carries a wheel bearing 24 in which the not shown axle of the front wheel 25 is stored.
Forhjulet 25 har p- sin ene side en sirkulær utsparing 26. The front wheel 25 has a circular recess 26 on one side.
I denne utsparingen strekker det seg inn en bæredel 29- Bæredelen 29 består av en nedragende arm 30 som ved hjelp av bolter 31 er festet til en sidevegg 32 på den L-formede bærebrakett 23, nærmere bestemt i det horisontale ben 33 av denne bærebrakett. Zrmen 30 fortsetter i en horisontal del 27 og er deretter bøyet om slik at det tilveiebringes en vertikal arm 28. A support part 29 extends into this recess. The support part 29 consists of a lowering arm 30 which, by means of bolts 31, is attached to a side wall 32 of the L-shaped support bracket 23, more specifically in the horizontal leg 33 of this support bracket. The arm 30 continues in a horizontal part 27 and is then bent over so that a vertical arm 28 is provided.
På armen 28 er det montert en hydraulisk motor 3^. Motoren 34 innbefatter et par ledningstilknytninger 35 og 36 hvortil ledninger 37 og 38 er fastgjort. Disse ledninger fører til en ikke vist hydraulisk pumpe og sump. Den hydrauliske væske som under trykk føres gjennom ledningene 37 og 38, bevirker drift av den hydrauliske motor 34, hvorved hjulet 25 drives. A hydraulic motor 3^ is mounted on the arm 28. The motor 34 includes a pair of wire attachments 35 and 36 to which wires 37 and 38 are attached. These lines lead to a hydraulic pump and sump not shown. The hydraulic fluid which is fed under pressure through the lines 37 and 38 causes operation of the hydraulic motor 34, whereby the wheel 25 is driven.
Da forhjulet 25 er en kombinasjon av et drivhjul og et styre-hjul, er det nødvendig at hjulet skal kunne dreies ved hjelp av styrestangen 21, samtidig som hjulet roterer. For å hindre at de hydrauliske ledninger 37 og 38 kommer i klem under denne styredreiing, er det anordnet en føring 39- Denne føring består av flere halvsirkuære skiver 40, 41 og 42 som er anordnet parallelt med hverandre. De holdes i innbyrdes avstand ved hjelp av forbindelseselementene 43, slik at det dannes rom 44 og 45 mellom skivene. Skivene 40, 41 og 42 ligger i et horisontalplan og strekker seg rundt benet 33 til den L-formede brakett 23. På grunn av dette arrangement kan ledningen 37 anordnes i rommet 44 mellom-skivene 40 og 41, mens ledningen 38 anordnes i rommet 42 mellom skivene 4l og 42. Når hjulet 25 dreies, vil også føringen 39 dreie seg og holde ledningene 37 og 38 fra hverandre . As the front wheel 25 is a combination of a drive wheel and a steering wheel, it is necessary that the wheel can be turned with the help of the steering rod 21, at the same time as the wheel rotates. In order to prevent the hydraulic lines 37 and 38 from getting pinched during this steering rotation, a guide 39 is arranged - This guide consists of several semicircular disks 40, 41 and 42 which are arranged parallel to each other. They are kept at a distance from each other by means of the connecting elements 43, so that spaces 44 and 45 are formed between the disks. The disks 40, 41 and 42 lie in a horizontal plane and extend around the leg 33 of the L-shaped bracket 23. Because of this arrangement, the wire 37 can be arranged in the space 44 between the disks 40 and 41, while the wire 38 is arranged in the space 42 between the disks 41 and 42. When the wheel 25 is turned, the guide 39 will also turn and keep the wires 37 and 38 apart.
I fig. 2 er opplagringen av de roterende feiebørster 46 og 47, såvel som opplagringen for fronthjørneskrapen 48 vist. På de frie endene til hjulakselen 17 er det opplagret de respektive ender 49 og 50 av bærestenger 51 og 52. En plate 53 er fastsveiset til bærestengene 51 og 52 nær disses frie ender. Platen 53 bærer monter-ingsplater 56 oh 57 for de respektive feiebørster 46 og 47. In fig. 2, the storage of the rotating sweeping brushes 46 and 47, as well as the storage for the front corner scraper 48 is shown. The respective ends 49 and 50 of support rods 51 and 52 are supported on the free ends of the wheel axle 17. A plate 53 is welded to the support rods 51 and 52 near their free ends. The plate 53 carries mounting plates 56 and 57 for the respective sweeping brushes 46 and 47.
Som vist i fig. 2 er stangen 51 kortere enn stangen 52. På den måten tilveiebringes det en diagonalt anordnet frontbuffer 58 som ikke bare er forbundet med de frie endene til stengene 51 og 52, men også er forbundet med stengenes respektive ytterflater, mellom stang-.endene, slik det går frem av fig. 2. På bufferens eller støtfangerens lengde side 59 er det montert en topp-plate 60 for skrapens bærekonstruksjon 6l. As shown in fig. 2, the rod 51 is shorter than the rod 52. In this way, a diagonally arranged front buffer 58 is provided which is not only connected to the free ends of the rods 51 and 52, but is also connected to the respective outer surfaces of the rods, between the rod ends, as it appears from fig. 2. On the length side 59 of the buffer or bumper, a top plate 60 for the scraper's support structure 6l is mounted.
Som vist i fig. 3 og 6 består skrapens bærekonstruksjon 6l av topp-platen 60 og med denne topp-platehengselforbundne armer 62 og 63 som værer en bunnplate 64. Bunnplaten 64 bærer fronthjørneskrapen 48. As shown in fig. 3 and 6, the scraper's support structure 6l consists of the top plate 60 and with this top plate hinge-connected arms 62 and 63 which are a bottom plate 64. The bottom plate 64 carries the front corner scraper 48.
Armene 62 og 63 er svingbart opplagret ved hjelp av svinge-tappene 66 og 67 i lagerblokker 68 og 69 på henholdsvis topp-platen 60 og bunnplaten 64. På denne måten dannes det et parallelogram, og derved kan bunnplaten beveges under påvirkning av stempelet 70 i en hydraulsylinder 71. Som det går frem av fig. 2 og 3 er hydraulsy-linderen 71 fastmontert på et øre 72 på støtfangeren 58. Den frie enden til stempelet 70 i sylinderen 71 er forbundet med en forlenget del av den ene svingetappen 67, dvs. den svingetapp som danner svinge-forbindelsen mellom lagerblokken 69 på bunnplaten 64 og svingearmen 63. c> The arms 62 and 63 are pivotably supported by means of pivot pins 66 and 67 in bearing blocks 68 and 69 respectively on the top plate 60 and the bottom plate 64. In this way a parallelogram is formed, and thereby the bottom plate can be moved under the influence of the piston 70 in a hydraulic cylinder 71. As can be seen from fig. 2 and 3, the hydraulic cylinder 71 is fixedly mounted on an ear 72 on the bumper 58. The free end of the piston 70 in the cylinder 71 is connected to an extended part of the one pivot pin 67, i.e. the pivot pin which forms the pivot connection between the bearing block 69 on the bottom plate 64 and the swing arm 63. c>
Mellom topp-platen 60 og hjørneskrapen 48 er det anordnet en fjær 73. Denne tjener til å klappe parallelogrammet som dannes av platene 60 og 64 sammen. I en slik sammenklappet stilling vil skrape-listen 65 være i løftet stilling, dvs. at den ikke lenger er i kontakt med gulvet som feies. A spring 73 is arranged between the top plate 60 and the corner scraper 48. This serves to clap the parallelogram formed by the plates 60 and 64 together. In such a folded position, the scraper strip 65 will be in a raised position, i.e. it is no longer in contact with the floor being swept.
Når sylinderen 71 pådras slik at stempelet 70 kjøres ut, vil vunnplaten fjerne seg fra topp-platen på grunn av parallelogram-leddanordningen. En slik bevegelse er antydet med stiplede linjer i fig. 6. På denne måten kan skrapen 48 bringes til kontakt med gulvet som feies. When the cylinder 71 is applied so that the piston 70 is driven out, the winch plate will remove from the top plate due to the parallelogram joint arrangement. Such a movement is indicated by dashed lines in fig. 6. In this way, the scraper 48 can be brought into contact with the floor being swept.
Bærekonstruksjonen for børstene 46 og 47 og hjørneskrapen 48 kan svinges bm akselen 17 ved hjelp av en hydraulsylinder 75. Som det går frem av fig. 2 er den frie enden til stempelet 74 i hydraul-sylinderen 75 ved 76 svingbart forbundet med bærerammens plate 53, mens den andre sylinderenden 75 er forbundet med et egnet lagersted på instrumentsøylen 12. Når sylinderen 75 pådras vil den kunne be-virke en heving eller senking av hele renseutstyret, slik at dette kan bringes til gulvkontakt eller løftes ut av fulvkontakt. The support structure for the brushes 46 and 47 and the corner scraper 48 can be pivoted about the shaft 17 by means of a hydraulic cylinder 75. As can be seen from fig. 2, the free end of the piston 74 in the hydraulic cylinder 75 is pivotably connected at 76 to the support frame's plate 53, while the other cylinder end 75 is connected to a suitable bearing location on the instrument column 12. When the cylinder 75 is applied, it will be able to cause an elevation or lowering the entire cleaning equipment, so that it can be brought to floor contact or lifted out of full contact.
Svingebevegelsen foregår hovedsakelig i vertikalplanet som følge av at svingeakselen har en relativt stor avstand fra selve børste- og skrapeanordningen. The swinging movement mainly takes place in the vertical plane as a result of the swing shaft having a relatively large distance from the brush and scraper device itself.
