Avfallsvogn med transport sko vi. Waste cart with transport shoes vi.
Denne oppfinnelse vedrører avfallsvog- This invention relates to waste transport
ner (søppelvogner) med en nedre skovl til løftning av avfallet ut fra avfallsrommet og en øvre skovl til å skyve avfallet over i samlebeholderen og presse det sammen. ner (garbage trucks) with a lower shovel for lifting the waste out of the waste room and an upper shovel for pushing the waste into the collection container and compressing it.
Ved en kjent anordning er det den mangel In the case of a known device, there is that deficiency
at der ved tetningsstedet mellom den nedre skovl og den fastsittende ifyllingsbeholder kan drysse gjennom fin aske. Sådanne ste- that fine ash can be sprinkled through at the sealing point between the lower blade and the fixed filling container. Such ste-
der kan ifølge erfaring ikke tettes full-stendig fordi det er tale om forholdsvis grove deler. according to experience, it cannot be sealed completely because these are relatively rough parts.
En annen mangel ved den samme anordning består i at dybden av ifyllings-rommet målt i vertikal retning praktisk ikke kan dimensjoneres stort nok. På den ene side rekker nemlig den sylindriske vegg under ifyllingsskovlen forholdsvis dypt ned hvor det må være tilstede den nødvendige bunnfrihet hos vognen, og på den annen side er den bakre kant av den faststående ifyllingsbeholder begrenset i sin høyde-stilling ved den fordring at avfallsbøtten av folkene må løftes over denne kant. Av- Another shortcoming of the same device is that the depth of the filling space, measured in the vertical direction, cannot practically be dimensioned large enough. On the one hand, the cylindrical wall below the filling bucket reaches relatively deep down where the necessary bottom clearance must be present in the cart, and on the other hand, the rear edge of the fixed filling container is limited in its height position by the requirement that the waste bucket of The people must be lifted over this edge. Of-
fallet vil dessuten neppe kunne gli ned på ifyllingsskovlen, men fremfor alt vil ved oppsvingning av skovlen en del av det inn-dryssede avfall kunne trykkes tilbake på ifyllingsbeholdere. moreover, the drop will hardly be able to slide down onto the filling bucket, but above all, by swinging the bucket, part of the sprinkled waste will be able to be pressed back onto the filling containers.
Disse mangler unngåes ifølge oppfinnelsen hovedsakelig derved at den nedre skovl selv er utformet som ifyllingsbehol- According to the invention, these shortcomings are avoided mainly by the fact that the lower bucket itself is designed as a filling container
der og dens bakre vegg således formet at dén øvre skovl ved oppsvingning av ifyllingsskovlen skyver seg inn mellom denne skovls bakre vegg og avfallet. there and its rear wall so shaped that the upper shovel, when the filling shovel swings up, pushes itself between this shovel's rear wall and the waste.
Hensiktsmessig anordnes der en om- Where appropriate, a re-
trent horisontal faststående vegg som fra trained horizontal fixed wall as from
ifyllingsskovlens svingeakse stikker inn i samlerommet og danner en forlengelse av ifyllingsskovlen i dennes øvre endestilling, the pivoting axis of the filling bucket protrudes into the collection space and forms an extension of the filling bucket in its upper end position,
og hvor for tømningen av samlebeholderen den ved bakre ende anbragte svingbare beholderdel kan svinges opp om en øvre horisontal akse, kan svingeaksen falle omtrent helt sammen med den øvre skovls akse. Når ifyllingsskovlen og transportskovlen betjenes ved pneumatiske eller hydrauliske arbeidssylindre, kan ifølge oppfinnelsen enkelte eller alle bevegelser av begge skovler etter en første kopling tvangstyres i avhengighet av hverandre. Endelig kan der anordnes en styreinnretning ved hvilken bare transportskovlen er koplet vilkårlig og dens arbeidsstempel mot slutten av slaget ved et til stempelstangen festet anslagsorgan påvirker et styreorgan for ifyllingsskovlens arbeidssylinder for å be-virke ifyllingsskovlens derpå følgende bevegelse. and where, for the emptying of the collection container, the pivotable container part arranged at the rear end can be swung up about an upper horizontal axis, the pivot axis can coincide almost completely with the axis of the upper blade. When the filling bucket and the transport bucket are operated by pneumatic or hydraulic working cylinders, according to the invention some or all movements of both buckets after a first coupling can be forcibly controlled in dependence on each other. Finally, a control device can be arranged in which only the transport bucket is connected arbitrarily and its working piston towards the end of the stroke by a stop member attached to the piston rod influences a control device for the filling bucket's working cylinder to cause the filling bucket's subsequent movement.
På tegningen viser fig. 1 en avfallsvogn ifølge oppfinnelsen i sideriss med beholderen i fartsstilling. Fig. 2 viser den samme vogn med samlebeholderen i tøm-ningsstilling. I fig. 3>—7 er vist enkelte stil-linger av fylle- og transportskovlen, alle i lengdesnitt. Fig. 3 viser snitt etter vognens lengdemidtplan, men fig. 4—7 viser snitt foran dette midtplan.

på vanlig måte bak styrehuset en samje-r beholder 2 som er åpen bare ved baksiden. På samlebeholderen er baktil en svingbar beholderdel 3 svingbart lagret om en øvre horisontal akse 4. I denne beholderdels in the usual way behind the wheelhouse a samje-r container 2 which is open only at the rear. At the rear of the collection container, a pivotable container part 3 is pivotally stored about an upper horizontal axis 4. In this container part
indre er nedentil anordnet en ifyllingsskovl 5 som er svingbar om den horisontale ak-se 6. Vertikalt derover er anordnet en aksel 7, om hvilken transportskovlen 8 er svingbart lagret. inside, a filling bucket 5 is arranged below which can be pivoted about the horizontal axis 6. A shaft 7 is arranged vertically above it, on which the transport bucket 8 is pivotably mounted.
I fig. 2 er samlebeholderen 2 opp-svingbar om en. bakre på vognrammen anordnet aksel 10 ved hjelp av en hydraulisk arbeidssylinder 11. I denne stilling kan avfallet gli ut. En kabel 12 er festet med sin forreste ende til vognrammen 9 og er lagt over ruller 13, 14 omkring samlebeholderen og griper ibaktil an på punkt 15 av beholderdelen 3 så at denne ved samlebeholde-rens svingning klappes opp om en aksel 4 og derved gir fri veien for utglidning av avfallet. In fig. 2, the collecting container 2 can be swung up about one. axle 10 arranged at the rear of the carriage frame by means of a hydraulic working cylinder 11. In this position the waste can slide out. A cable 12 is attached with its front end to the carriage frame 9 and is laid over rollers 13, 14 around the collection container and grips backwards at point 15 of the container part 3 so that when the collection container oscillates, it is folded up on an axle 4 and thereby gives free the way for the waste to slip.
Fig. 3 viser ifyllingsskovlen 5 i dens Fig. 3 shows the filling bucket 5 in its
nedre endestilling hvori den fylles med avfall. Skovlen består av to sirkelbueformede vegger 20, 21 som danner et trau, og- de to endevegger 22 som ifølge fig. 8 ligger mellom beholderdelens 3 sidevegger og som hver især ved hjelp av en filtstrimmel 23 er tettet mot denne. Veggen 21 bærer ved overkanten en list 24, f. eks, av gummi eller tre, til opplegning av avfallsbøtten. Arbeidssylinder' 25 med hvilken ifyllingsskov-len 5 svinges, griper med aksel 26 inn i en gaffel 27 som er festet på skovlen. Stempelstangen 28 er leddet til'aksel 30 i en lomme 29 anbrakt på beholderdelen 3. Lommen 24 danner en utvidelse av en hul bær edel 31. Transportskovlen 8 er i fig. 3 vist i sin forreste endestilling, hvori den lukker samlebeholderen 2 baktil så at avfallet ikke kan-, falle ut, Transportskovlen 8 betjenes ved hjelp av arbeidssylinder en 35 som er svingbart lagret om aksel 36 mellom ører 37 på beholderdelen 3. Stempelstangen 38 er svingbart forbundet med aksel 39 på transportskovlen 8. Som fig. 4 viser er transportskovlen 8 ved hjelp av arbeidssylinderen. 35 svinget ut til sin høyre arbeidsstilling, mens den med- avfall fylte ifyllingsskovl 5 ennå er i sin nedre stilling. lower end position in which it is filled with waste. The bucket consists of two circular arc-shaped walls 20, 21 which form a trough, and the two end walls 22 which, according to fig. 8 lies between the 3 side walls of the container part and each of which is sealed against this by means of a felt strip 23. The wall 21 carries at the upper edge a strip 24, e.g. of rubber or wood, for placing the waste bin. Working cylinder 25 with which the filling bucket 5 is swung engages with shaft 26 in a fork 27 which is attached to the bucket. The piston rod 28 is connected to the shaft 30 in a pocket 29 placed on the container part 3. The pocket 24 forms an extension of a hollow bearing shaft 31. The transport bucket 8 is in fig. 3 shown in its front end position, in which it closes the collection container 2 at the rear so that the waste cannot fall out. The transport bucket 8 is operated by means of a working cylinder 35 which is pivotally mounted on the shaft 36 between lugs 37 on the container part 3. The piston rod 38 is pivotable connected with shaft 39 on the transport bucket 8. As fig. 4 shows the transport vane 8 by means of the working cylinder. 35 swung out to its right working position, while the filling bucket 5 filled with waste is still in its lower position.
Fig. 5 viser neste skritt. Her er ifyllingsskovlen 5 svinget opp ved hjelp av arbeidssylinderen 25. Transportskovlen 8 har da skjøvet seg inn mellom ifyllings- Fig. 5 shows the next step. Here, the filling bucket 5 is swung up with the help of the working cylinder 25. The transport bucket 8 has then pushed itself between the filling
skovlens ytre vegg 21 og det deri værende avfall. the bucket's outer wall 21 and the waste therein.
■Som fig. 6 viser er transportskovlen 8 igjen svinget til sin venstre endestilling og dermed har den skjøvet avfallet inn i samlebeholderen 2. Når denne er fylt, vil transportskovlen 8 presse det overskjøvne avfall ytterligere sammen i samlebeholderen. Sirkelbuen for ifyllingsskovlens vegg 20 svarer i sin form til bevegelsen av ■As fig. 6 shows, the transport shovel 8 has again swung to its left end position and thus it has pushed the waste into the collection container 2. When this is filled, the transport shovel 8 will press the pushed waste further together in the collection container. The circular arc for the wall 20 of the filling bucket corresponds in its shape to the movement of
transportskovlens 8 underkant. Veggen 40 for den hule bæredel 31 svarer også til formen for denne sirkelbue. the lower edge of the transport bucket 8. The wall 40 of the hollow support part 31 also corresponds to the shape of this circular arc.
I fig. 7 er den tømte ifyllingsskovl 5 ved hjelp av arbeidssylinderen 25 igjen svinget tilbake i sin utgangsstilling, hvori den på nytt kan fylles fra avfallsbøtten. Transportskovlen 8 forblir herunder i sin lukkestilling. In fig. 7, the emptied filling bucket 5 is again swung back into its starting position by means of the working cylinder 25, in which it can be filled again from the waste bin. The transport bucket 8 remains in its closed position below.
Åv den skjematiske fig. 9 sees at arbeidssylinderen 25 for bevegelsen av ifyllingsskovlen 5 og arbeidssylinderen 35 for bevegelsen av transportskovlen 8 er utformet dobbeltvirkende. Til de to sylin-dersider slutter seg oljeledninger 41, 42 og 43, 44 gjennom hvilke trykkoljen til-føres og bortledes. See the schematic fig. 9 it can be seen that the working cylinder 25 for the movement of the filling bucket 5 and the working cylinder 35 for the movement of the transport bucket 8 are designed to be double-acting. The two cylinder sides are joined by oil lines 41, 42 and 43, 44 through which the pressure oil is supplied and removed.
Til venstre i fig. 9 er vist en styreinnretning. Her er der i et hus 50 lagret en styreaksel 51 som bærer to likedanne men motsattrettede styrekammer 52, 53 og be-tjeningen foregår fra en håndarm 54. Begge kammer betjener hver sin av to likeover-for hverandre og under hverandre liggende styresleider 55, med hvilke gjennomgangen for de to kanaler 56 og 57 sperres eller frigis. On the left in fig. 9 shows a control device. Here, in a housing 50, a steering shaft 51 is stored which carries two identical but oppositely directed steering chambers 52, 53 and the operation takes place from a hand arm 54. Both chambers are each operated by two steering slides 55 lying opposite and below each other, with which the passage for the two channels 56 and 57 is blocked or released.
En tannhjulsoljepumpe 60 suger oljen for arbeidssylinderne fra en beholder 61 og fører den gjennom en ledning 62 til ledningene 56 og 57 i huset 50. I den tegnede stilling av styreakselen strømmer trykkoljen gjennom ledningen 63 gjennom sylin-derens 35 nedre rom. Som følge herav vil stemplet forskyves oppover og bevege transportskovlen 8 fra den i fig. 3 til den i fig. 4 viste stilling. Når stemplet nærmer seg en-destillingen støter et på stempelstangen 38 anbrakt anslag 64 tilbakeslagsventilen A gear oil pump 60 sucks the oil for the working cylinders from a container 61 and leads it through a line 62 to the lines 56 and 57 in the housing 50. In the drawn position of the steering shaft, the pressure oil flows through the line 63 through the cylinder 35's lower chamber. As a result, the piston will shift upwards and move the transport vane 8 from the one in fig. 3 to that in fig. 4 shown position. When the piston approaches the end position, a stop 64 placed on the piston rod 38 hits the non-return valve
65 opp. Den fra pumpen 60 viderebefordre-de trykkolje strømmer gjennom denne ventil og tilbakeslagsventilen 66, som åpner seg automatisk og over i ledningen 41 i sy-linderens 25 overside og skyver dens stem-pel nedover. Derved svinges ifyllingsskovlen 5 op'p fra stillingen i fig. 4 til stillingen i fig. 5. Ved omlegning av armen 54 nedover svinges kammene 52 og 53-180°. Man vil se at dermed kommer først trykkoljen gjennom ledningen 62 over kanalene 70, 57 65 up. The pressurized oil forwarded from the pump 60 flows through this valve and the non-return valve 66, which opens automatically and into the line 41 in the upper side of the cylinder 25 and pushes its piston downwards. Thereby, the filling bucket 5 is swung upwards from the position in fig. 4 to the position in fig. 5. When repositioning the arm 54 downwards, the cams 52 and 53 are swung through 180°. It will be seen that the pressure oil thus first comes through the line 62 over the channels 70, 57
og ledningene 42, 43 inn i oversiden av and the wires 42, 43 into the upper side of
sylinderen 35. Stemplet forskyves nedover the cylinder 35. The piston is displaced downwards
og beveger transportskovlen fra stillingen and moves the transport bucket from its position
