Description

Strøanordning til strøing av kornformet materiale. Spreading device for spreading granular material.

Denne oppfinnelse vedrører en strø-anordning til strøing av fast, kornformet materiale over marken, særlig over vei-baner; startbaner på flyplasser og lignende. This invention relates to a spreading device for spreading solid, granular material over the field, particularly over roadways; runways at airports and the like.

Strøanordninger av den her gjeldende Spreading devices of the one applicable here

art er tidligere kjent. Det er også kjent å utstyre en strøvogn med et transportbelte som fører strømaterialet til en utleverings-innretniing. species is previously known. It is also known to equip a litter wagon with a conveyor belt that carries the litter material to a delivery facility.

Hensikten med oppfinnelsen er å til-veiebringe en slik strøanordning som kan brukes til samtidig strøing av forskjellige materialer, så som sand og salt, sand og aske, grus og sand og lignende. En annen hensikt med oppfinnelsen er å utføre anordningen slik at forholdet mellom de ut-leverte materialer kan varieres under an-vendelse av manuell kraft etter behov. The purpose of the invention is to provide such a spreading device which can be used for simultaneous spreading of different materials, such as sand and salt, sand and ash, gravel and sand and the like. Another purpose of the invention is to design the device so that the ratio between the delivered materials can be varied using manual force as needed.

Ved de tidligere kjente anordninger By the previously known devices

utstyrt med bare en transportør var blan-dingen av forskjellige materialer enten ikke mulig eller måtte foretas for hånd. Anordningen i henhold til oppfinnelsen fører der-for med seg en vesentlig forenkling av strøingsoperasjonen samtidig som den gjør det mulig at det utstrødde lag avpasses best mulig etter de lokale forhold. equipped with only one conveyor, the mixing of different materials was either not possible or had to be done by hand. The device according to the invention therefore leads to a significant simplification of the spreading operation at the same time as it makes it possible for the spread layer to be adjusted as best as possible to the local conditions.

Anordningen i henhold til oppfinnelsen The device according to the invention

omfatter en beholder for en eller flere sorter kornformet materiale og transport-innretninger og strøinnretninger for samme og utmerker seg ved at den er utstyrt med minst to endeløse transportører som samtidig og fra to motsatte retninger fører det nevnte materiale eller materialer til en utløpssone på midten av beholderens bunn, og at det under utløpssonen på en i og for seg kjent måte er anordnet innret- comprises a container for one or more types of granular material and transport devices and spreading devices for the same and is distinguished by the fact that it is equipped with at least two endless conveyors which simultaneously and from two opposite directions lead the said material or materials to an outlet zone in the middle of the bottom of the container, and that under the outlet zone, in a manner known per se, a device is arranged

ninger for utstrøing av det nevnte mate-teriale. Som følge av at transportørene er anordnet slik at de fra motsatte retninger fører materialet til en utløpssone, kan den siste være anordnet i forholdsvis stor avstand fra vedkommende kjøretøys bakhjul, slik at hjulene alltid vil rulle på en vel overstrødd flate. nings for spreading the aforementioned material. As a result of the conveyors being arranged so that they lead the material from opposite directions to an outlet zone, the latter can be arranged at a relatively large distance from the relevant vehicle's rear wheel, so that the wheels will always roll on a well-strewn surface.

Transportørene består av endeløse belter, hvis øvre løp sammen utgjør beholderens bunn og er innrettet til å beveges i motsatte retninger mot hinannen. Beltene er anordnet slik at det mellomrom som ut-gjør utløpssonen er dannet på det sted hvor beltene skifter bevegelsesretningen. The conveyors consist of endless belts, the upper runs of which together form the bottom of the container and are arranged to move in opposite directions to each other. The belts are arranged so that the space that makes up the outlet zone is formed at the place where the belts change direction of movement.

En trakt med åpen bunn er anordnet i den nevnte utløpssone for å motta materiale som leveres fra beltene og føre det opp på strøinnretningene hvor de siste omfatter i det minste en skive som er anordnet for rotasjon i horisontalplanet eller et plan som i det vesentlige er horisontalt, og som på sin øvre flate er forsynt med et antall ribber som strekker seg fra skive-overflatens senter utover. A hopper with an open bottom is arranged in the aforementioned outlet zone to receive material delivered from the belts and lead it up onto the spreading devices where the latter comprise at least a disk arranged for rotation in the horizontal plane or a plane which is essentially horizontal , and which on its upper surface is provided with a number of ribs which extend from the center of the disk surface outwards.

Anordningen er også utstyrt med to ved siden av hinannen anordnede skiver som roterer i innbyrdes motsatte retninger, hvor ribbene på skivene er krummet bakover i forhold til rotasjonsretningen, og hvor, sett i beholderens bevegelsesretning, den venstre skive beveger seg i retning med urviseren og den høyre skive beveger seg i retning mot urviseren. Umiddelbart ved beltenes avleveringsender er anordnet sluseporter for regulering av den materialmengde som fra hvert beite leveres til trakten. The device is also equipped with two discs arranged next to each other which rotate in mutually opposite directions, where the ribs on the discs are curved backwards in relation to the direction of rotation, and where, viewed in the direction of movement of the container, the left disc moves in a clockwise direction and the the right disc moves in a counter-clockwise direction. Immediately at the delivery end of the belts, sluice gates are arranged to regulate the amount of material that is delivered from each pasture to the hopper.

På siden av skivene kan være anordnet sluseporter for regulering av den materialmengde som fra hvert belte leveres til trakten. Sluice gates can be arranged on the side of the disks for regulating the amount of material that is delivered from each belt to the hopper.

Oppfinnelsen skal forklares ved hjelp av et eksempel under henvisning til teg^ ningene, hvor: Fig. 1 viser fra siden en beholder som er anordnet på et motordrevet kjøretøys understell, hvor noen deler er fjernet for klarhets skyld, og fig. 2 er et perspektiv-riss av en spredningsinnretning. The invention shall be explained by means of an example with reference to the drawings, where: Fig. 1 shows from the side a container which is arranged on the undercarriage of a motor-driven vehicle, where some parts have been removed for the sake of clarity, and Fig. 2 is a perspective view of a spreading device.

Ifølge fig. 1 omfatter anordningen en beholder 1 som er montert på understellet 2 av et motordrevet kjøretøy. Beholderen er utformet rektangulært og med vegger som heller innover mot beholderens bunn, slik at materiale har lettere for å falle mot beholderens bunn. Den siste utgjøres av de øvre løp 3 henholdsvis 4 av de to ende-løse belter 5 henholdsvis 6 som drives fra kjøretøyets kraftuttak. According to fig. 1, the device comprises a container 1 which is mounted on the undercarriage 2 of a motor-driven vehicle. The container is designed rectangular and with walls that slope inwards towards the bottom of the container, so that material has an easier time falling towards the bottom of the container. The latter is made up of the upper runs 3 and 4 of the two endless belts 5 and 6, respectively, which are driven from the vehicle's power take-off.

Beltene 5 og 6 er anordnet på tverrgående aksler, og beltet 5 befinner seg i beholderens bakre halvdel, mens beltet 6 befinner seg i beholderens fremre halvdel, slik at de utfyller beholderens bunn, unn-tatt en tverrgående utløpsåpning 7 som ligger mellom beltene 5, 6 på midten av beholderbunnen. Det bakre beltes øvre løp 3 beveger seg forover, mens det fremre beltes øvre løp 4. beveger seg bakover, slik at begge belteløp skifter sin bevegelsesretning ved utløpsåpningen 7, med den følge at det på. beltene transporterte materiale føres ut av beholderen gjennom ut-løpsåpningen 7. The belts 5 and 6 are arranged on transverse shafts, and the belt 5 is located in the rear half of the container, while the belt 6 is located in the front half of the container, so that they fill the bottom of the container, except for a transverse outlet opening 7 which lies between the belts 5, 6 in the middle of the container bottom. The rear belt's upper race 3 moves forwards, while the front belt's upper race 4. moves backwards, so that both belt races change their direction of movement at the outlet opening 7, with the result that on. material transported by the belts is led out of the container through the outlet opening 7.

I utløpsåpningen 7 og lavere enn belte-løpenes 3, 4, nivå er anordnet en trakt 8 med åpen bunn. Den strekker seg nedover under kj øretøyunderstellet og samler og-utleverer strømaterialer som da faller ned på de øvre flater 9 av to like skiver 10 som roterer om vertikale aksler, hvilket vil si at skivenes 10 øvre flater 9 er anordnet horisontalt eller i det vesentlige horisontalt. Skivene drives som beltene fra kraft-uttaket. Ved den på fig. 2 skjematisk viste utførelse overføres drivkraften fra kraft-uttaket over en mellomaksel til to tann-hjulutvekslingskasser, hvorav den ene uten retningsforandring fører driften til det ene belte og til den ene skives drivaksel, mens den annen skifter drivretningen og over-fører driften til det annet belte og til den annen skive: De to skiver 10 er anordnet ved siden av hinannen og på tvers av kjøretøyet. Sett i kjøretøyets bevegelsesretning roterer den venstre skive i retning med urviseren og den høyre skive i retning mot urviseren. In the outlet opening 7 and lower than the level of the belt runs 3, 4, a funnel 8 with an open bottom is arranged. It extends downwards under the earpiece base and collects and delivers bedding materials which then fall onto the upper surfaces 9 of two identical discs 10 which rotate about vertical axes, which means that the upper surfaces 9 of the discs 10 are arranged horizontally or substantially horizontally . The discs are driven like the belts from the power take-off. At the one in fig. 2 schematically shown embodiment, the driving force is transferred from the power take-off via an intermediate shaft to two gear-wheel gearboxes, one of which without a change of direction drives the drive to one belt and to one disc drive shaft, while the other changes the drive direction and transfers the drive to the other belt and to the other disk: The two disks 10 are arranged next to each other and across the vehicle. Seen in the direction of movement of the vehicle rotates the left disc in a clockwise direction and the right disc in a counter-clockwise direction.

Som vist på fig. 2, har skiven 10 en sentral åpning 15 som er omgitt av et nav 16 hvis innervegg er forsynt med et kile-spor 17 for fastgjøring av skiven på driv-akselen. Skiven er langs sin periferi utformet med et nedsenket kantparti 18 og bærer fem like ribber 19 som løper ut fra navet 16 og er anordnet i like stor innbyrdes avstand. Ribbene har L-formet tverrsnitt, og ribbenes ene flens 20 ligger på og er klinket til skiven, mens den annen flens 21 stikker vertikalt opp fra skivens øvre flate. Ribbene 19 er krummet bakover i forhold til skivens omdreiningsretning over en vinkel på nesten 180°, og ribbenes yt-terste ender ligger i avstand fra skivens periferi. As shown in fig. 2, the disc 10 has a central opening 15 which is surrounded by a hub 16, the inner wall of which is provided with a wedge groove 17 for fixing the disc on the drive shaft. The disc is designed along its periphery with a sunken edge portion 18 and carries five equal ribs 19 which run out from the hub 16 and are arranged at an equal distance from each other. The ribs have an L-shaped cross-section, and one flange 20 of the ribs lies on and is riveted to the disk, while the other flange 21 projects vertically up from the upper surface of the disk. The ribs 19 are curved backwards in relation to the direction of rotation of the disc over an angle of almost 180°, and the outermost ends of the ribs are located at a distance from the periphery of the disc.

En skjerm kan være anordnet på hver side av kjøretøyet på siden av platene. Skjermen består av en plate som henger ned fra en knekt på kjøretøyets understell, som kan svinges om en av sine sidekanter. Hver skjerms ytre kant,, dvs. den som. ligger lengst fra opphengslinjen, kan være forbundet med beholderens nærmeste side-vegg ved hjelp av gurter. eller stropper, med. forstillbar lengde, slik at vinkelen: mellom skjermen og det strødde materials: bane kan varieres hensiktsmessig for innstilling' av en riktig strøbredde. A screen may be provided on each side of the vehicle on the side of the plates. The screen consists of a plate that hangs down from a jack on the vehicle's undercarriage, which can be swung around one of its side edges. Each screen's outer edge,, i.e. the one that. located farthest from the suspension line, can be connected to the nearest side wall of the container by means of straps. or straps, with. adjustable length, so that the angle between the screen and the path of the spread material can be varied appropriately for setting a correct spread width.

Den materialmengde som skal strøes ut som av beltene 5<;> og 6 først skal føres inn i trakten 8, kan varieres ved hjelp av sluseporter som er anordnet mellom beholderens sidevegger over beltene" umiddelbart ved beltenes avleveringsender. The amount of material that is to be spread out as from the belts 5<;> and 6 is first to be fed into the funnel 8, can be varied by means of sluice gates which are arranged between the side walls of the container above the belts" immediately at the delivery end of the belts.

Ved en modifisert utførelse av anordningen kan beholderen, de endeløse belter og strøinnretningene være anordnet på en tilhenger som trekkes etter et kjøretøy, hvor strøinnretningene og beltene enten drives fra tilhengerens kjøren jul eller fra kjøretøyets kraftuttak. Alternativt kan drivinnretnlngene drives fra sin egen motor. In a modified version of the device, the container, the endless belts and the spreading devices can be arranged on a trailer that is pulled by a vehicle, where the spreading devices and belts are either driven from the trailer's drive or from the vehicle's power take-off. Alternatively, the drive devices can be driven from their own motor.

Ved hjelp av anordningen som omfatter oppfinnelsen kan grus, sand, aske: og annet kornaktig materiale1 strøs slik. at det danner et teppe umiddelbart: foran: kjøre-tøyets hjul,.hvilke som kjent er særlig..for-delaktig ved bakhjulsdrevne kjøretøyer, som strør materialer over islagte kjørebaner: Beltene kan også føre forskjellige materialer, som f. eks. salt og sand, som ved en hensiktsmessig innstilling av sluse-portene i ønskede forhold kan blandes med hinannen. With the aid of the device comprising the invention, gravel, sand, ash and other granular material1 can be sprinkled like this. that it forms a carpet immediately: in front: the wheels of the vehicle, which, as is known, are particularly advantageous for rear-wheel drive vehicles, which spread materials over icy roads: The belts can also carry different materials, such as e.g. salt and sand, which can be mixed with each other when the sluice gates are set appropriately in the desired ratio.
