Description

i DK 168726 B1in DK 168726 B1

Opfindelsen angår et doseringsapparat, især til brug· i forbindelse med en spreder, ved udbringning af pulverformet eller granulært materiale, og som omfatter en beholder for materialet og en under beholderen anbragt båndtransportør med en øvre 5 transportbane, som udgør i det mindste en del af beholderens bund, og som mellem sig og en set i båndets bevægelsesretning bageste beholdervæg afgrænser en udløbsspalte for materialet.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a dosing apparatus, particularly for use in conjunction with a spreader, in the application of powdered or granular material, comprising a container for the material and a belt conveyor disposed below the container which comprises at least a portion of the bottom of the container and defining an outlet gap for the material between itself and a rearward wall of the tape, seen in the direction of movement of the belt.

Sådanne doseringsapparater er almindeligt kendte til spredere, 10 idet båndtransportøren under drift kontinuerligt fører en given materialemængde ud af beholderen gennem spalten og videre frem til en skakt, der fører frem til en spredetallerken.Such dosing apparatus are generally known to spreader, with the belt conveyor continuously operating a given amount of material out of the container through the slot and onward to a shaft leading to a spreading plate.

Det er imidlertid et problem ved kendte doseringsapparater, at spalteåbningen efter nogen tids drift tilstoppes, således 15 at der ikke føres den ønskede materialemængde ud af beholderen af båndtransportøren. Dette bevirker endvidere, at der ikke udbringes den ønskede materialemængde af sprederen.However, it is a problem with known dosing apparatus that after some time the slot opening is blocked so that the desired quantity of material is not carried out of the container by the belt conveyor. This further prevents the desired amount of material from being released by the spreader.

Således kendes fra europæisk offentliggørelsesskrift nr. 0149274 et 20 doseringsapparat af den indledningsvis nævnte art omfattende en beholder og en herunder anbragt båndtransportør med en øvre transportbane. På den set i den øvre transportbanes bevægelsesretnings bageste beholdervæg er der drejeligt monteret en knuseplade, som mellem sig og den øvre transportbane afgræn-25 ser en udløbsspalte. Knusepladen er hovedsageligt beliggende indvendigt i beholderen og er indrettet til at sønderdele klumper af materiale umiddelbart før spalten, således at materialet forlader beholderen i granulær form. Ved at knusepladen er drejeligt monteret, kan større ikke knuste klumper også 30 forlade beholderen, idet spaltehøjden forøges ved nævnte drej ning. Herved ændres imidlertid doseringsmængden.Thus, from European Publication No. 0149274 a dosing apparatus of the kind mentioned initially comprising a container and a belt conveyor including an upper conveyor path is known. A crush plate is mounted on the rear container wall seen in the rear direction of movement of the upper conveyor path which defines an outlet gap between itself and the upper conveyor path. The crushing plate is mainly located inside the container and is arranged to disintegrate clumps of material immediately before the slot so that the material leaves the container in granular form. Also, because the crush plate is rotatably mounted, larger non-crushed lumps can leave the container as the slit height is increased by said rotation. Hereby, however, the dosage amount changes.

Formålet med opfindelsen er at anvise et enkelt og billigt doseringsapparat af den indledningsvis nævnte art, som er 35 i stand til meget nøjagtigt og kontinuerligt at afgive en ønsket materialemængde.The object of the invention is to provide a simple and inexpensive dosing apparatus of the kind mentioned above, which is capable of delivering a desired quantity of material very accurately and continuously.

Til opnåelse af dette formål er doseringsapparatet ifølge DK 168726 B1 2 opfindelsen ejendommeligt ved, at der i umiddelbar nærhed af udløbsspalten og under den øvre transportbane er anbragt et vibrationsaggregat til·vibrering af den øvre transportbane og derved ændring af udløbsspaltens højde over en del af dennes 5 bredde under opretholdelse af i det væsentlige konstant udløbs spalteareal .To achieve this purpose, the dosing apparatus according to DK 168726 B1 2 is characterized in that in the immediate vicinity of the outlet slot and below the upper conveying path, a vibration assembly is provided for vibrating the upper conveying path and thereby changing the height of the outlet gap over part of its 5 width while maintaining substantially constant outlet gap area.

Herved opnås, at der opstår en bevægelse af materialet ved spalteåbningen, således at en tilsætning af denne forhindres, ^0 og at materialet herved kontinuerligt og i meget ensartet mængde føres ud gennem spalten af transportbåndet, idet der set på tværs af transportbåndets bevægelsesretning til trods for, at spaltehøjden varierer over dens bredde, til stadighed føres samme materialemængde ud på båndet. Især ved dosering ^5 af små materialemængder, hvor den gennemsnitlige spalte er meget lille, f.eks. i størrelsesordenen 2-3 mm, er denne spaltevariation af stor betydning for undgåelse af en tilsætning af spalten, idet enkeltkorn med større tværmål end den gennemsnitlige spaltehøjde kan passere spalten.This results in a movement of the material at the slot opening, so that an addition thereof is prevented, and the material is thereby continuously and in very uniform quantity discharged through the gap of the conveyor belt, as seen across the conveyor belt's direction of movement despite for the height of the slit varies over its width, the same amount of material is constantly carried out on the belt. Especially at dosage ^ 5 of small amounts of material where the average gap is very small, e.g. in the order of 2-3 mm, this gap variation is of great importance in avoiding the addition of the gap, as single grains with larger cross-dimensions than the average gap height can pass the gap.

2020

Ifølge opfindelsen kan vibrationsaggregatet udgøres af en med mindst ét fremspring forsynet aksel, som er således drejeligt lejret om en akse, der forløber vinkelret på transportbåndets transportretning, at fremspringet eller fremspringene ved 25 drejning af aksen påvirker den øvre transportbane til ændring af udløbsspaltens højde, i det mindste over en del af dennes bredde.According to the invention, the vibration assembly can be constituted by a shaft provided with at least one projection which is so pivotally mounted about an axis which runs perpendicular to the conveyor belt's direction that the projection or projections affect rotation of the upper conveyor path to change the height of the outlet gap. at least over part of its width.

Herved fremkommer et særligt enkelt og billigt doseringsappa-3q rat, ved hvilket akselens fremspring ifølge en yderligere udførelsesform for opfindelsen kan udgøres af et antal over akselens længde jævnt fordelte og excentrisk anbragte cirkulære knastskiver, hvis toppunkter (dvs. det punkt, som ligger i størst afstand fra akselens centerlinie) er forsat med samme 35 vinkel i forhold til hinanden.This results in a particularly simple and inexpensive dosing apparatus, in which the shaft projection according to a further embodiment of the invention can be constituted by a number of evenly spaced and eccentrically arranged circular cam discs, the apexes of which are greatest distance from the center line of the shaft) is set at the same angle to each other.

I denne forbindelse kan desuden ifølge opfindelsen akselen være forsynet med fire knastskiver, der er forsat 90° i forhold 3 DK 168726 B1 til hinanden.In this connection, in addition, according to the invention, the shaft may be provided with four cam discs which are positioned 90 ° relative to each other.

Denne udførelsesform.har i praksis vist sig særlig hensigtsmæssig.In practice, this embodiment has proved particularly convenient.

Yderligere fordelagtige udførelsesformer for doseringsappara-tet ifølge opfindelsen fremgår af de øvrige uselvstændige krav og den efterfølgende beskrivelse, hvor opfindelsen forklares nærmere under henvisning til tegningen, hvor 10 fig. 1 viser skematisk og set fra siden et doseringsapparat ifølge opfindelsen benyttet i forbindelse med en spreder, der er påmonteret en lastvogn, og 15 fig. 2 et delsnit efter linien II-II i fig. 1.Further advantageous embodiments of the dosing apparatus according to the invention will be apparent from the other dependent claims and the following description, the invention being explained in more detail with reference to the drawing, in which: FIG. 1 is a diagrammatic side view of a dosing apparatus according to the invention used in connection with a spreader mounted on a truck; and FIG. 2 is a sectional view taken along line II-II of FIG. First

Fig. 1 og 2 viser et doseringsapparat ifølge opfindelsen, som er anbragt på ladet 1 af en delvis vist lastvogn 2. Dose-ringsapparatet omfatter en beholder 3 for det strømateriale, 20 som skal udbringes. Under beholderen 3 er der anbragt en bandtransportør 4 med en øvre transportbane 5, som udgør beholderens bund, idet der under nævnte transportbane er anbragt en giideskinne 6, mod hvilken transportbåndets øvre transportbane 5 ligger an. Båndtransportørens 4 transportbånd 7 drives 25 i pilens D retning af en drivrulle 8, der er beliggende uden for beholderens 3 set i kørselsretningen K bageste væg 9, og er ført omkring en friløbsrulle 10, der er beliggende ved beholderens set i kørselsretningen forreste væg 11. Drivrullen 8 trækkes ved hjælp af et kørehjul 12, som løber på jorden 3 0 eller vejbanen, således at båndhastigheden bliver afhængig af den hastighed, hvormed lastvognen kører.FIG. 1 and 2 show a metering apparatus according to the invention, which is arranged on the load 1 of a partially shown truck 2. The metering apparatus comprises a container 3 for the feedstock to be dispensed. Underneath the container 3 is a belt conveyor 4 having an upper conveyor 5, which constitutes the bottom of the container, a guide rail 6 against which the upper conveyor 5 of the conveyor belt abuts. The conveyor belt 7 of the belt conveyor 4 is driven 25 in the direction of arrow D by a drive roller 8 located outside of the container wall 3 in the driving direction K rear wall 9, and is guided around a freewheel roller 10 located at the container wall in the driving direction front wall 11. The drive roller 8 is pulled by means of a drive wheel 12 running on the ground 30 or the roadway, so that the tire speed becomes dependent on the speed at which the truck travels.

I beholderens bageste væg 9 er der indrettet en doserings-35 4 DK 168726 B1 lem 13/ som kan forskydes i lodret retning, således at spalteåbningen 14 mellem dennes nederste kant 15 og den øvre transportbanes 5 øvre overflade kan justeres med henblik på at justere den materialemængde, som trækkes ud af beholderen 5 3 af båndtransportøren. Umiddelbart under doseringslemmen 13 er der i en tværgående åbning i giideskinnen 6 neden under den øvre transportbane 5 anbragt et vibrationsaggregat 16, der er indrettet til at vibrere den øvre transportbane 5.In the rear wall 9 of the container, a dosing member 13 is provided which can be displaced in the vertical direction so that the gap opening 14 between its lower edge 15 and the upper surface of the upper conveyor 5 can be adjusted to adjust it. amount of material pulled out of the container 5 3 by the belt conveyor. Immediately below the metering flap 13, in a transverse opening in the guide rail 6 below the upper conveying path 5, a vibration assembly 16 arranged to vibrate the upper conveying path 5 is arranged.

20 Dette vibrationsaggregat udgøres, som det tydeligere fremgår af fig. 2, af fire knastskiver 17,17,17",17'", der er anbragt excentrisk på en aksel 18, som er drejeligt lejret om en akse, der står vinkelret på transportbåndets transportretning T.This vibration assembly is constituted, as can be seen more clearly in FIG. 2, of four cam washers 17,17,17 ", 17 '" disposed eccentrically on a shaft 18 pivotally mounted about an axis perpendicular to the conveying direction T.

De fire knastskiver 17,17',17'', 17''1 er jævnt fordelte over 25 akselens 18 længde, og deres toppunkter dvs. det punkt, som ligger i størst afstand fra akselens 18 centerlinie, er forsat 90° i forhold til hinanden, se fig.The four cam washers 17,17 ', 17' ', 17' '1 are evenly distributed over the length of the shaft 18 and their apexes ie. the point which is most distant from the center line of the shaft 18 is set at 90 ° relative to each other, see fig.

1, Knastskiverne 17,17',17'1,17" 1 og dermed akselen 18 drives til rotation ved skivernes anlæg mod den øvre transportbanes 20 underside.1, The cam discs 17,17 ', 17'1,17 "1 and thus the shaft 18 are driven for rotation at the discs against the underside of the upper conveyor 20.

På grund af knastskiverne vil der ved drift af transportbåndet 8 til stadighed opstå en bevægelse af strømaterialet ved spalteåbningen 14, således at en tilsætning af denne forhindres.Due to the cam discs, during operation of the conveyor belt 8, movement of the flow material at the slot opening 14 will occur continuously, so that an addition thereof is prevented.

25 Herved vil strømaterialet af transportbåndet 7 kontinuerligt og i den ønskede mængde blive ført ud gennem spalten 14 og videre frem til drivrullen 8, ved hvilken det falder ned i· en skakt 20 og ned på en spredeskive 21, som spreder strømaterialet ud på jorden eller kørebanen i den ønskede mængde.In this way, the flow material of the conveyor belt 7 will be continuously and in the desired quantity passed out through the slot 14 and further up to the drive roller 8, whereby it falls into a shaft 20 and onto a spreading disc 21 which spreads the flow material to the ground or the lane in the desired amount.

30 Den udspredte mængde pr. arealenhed vil som følge af, at trans portbåndet drives vejafhængigt, være konstant.30 The dispersed amount per as a result of the conveyor belt being road dependent, the unit of land will be constant.

Opfindelsen kan ændres på mange måder, uden at der afviges fra opfindelsens idé; således kan doseringsapparatet eksem-35 pelvis anvendes i en selvkørende spreder eller til andet ud styr end spredere.The invention can be changed in many ways without departing from the idea of the invention; for example, the metering apparatus can be used, for example, in a self-propelled spreader or for equipment other than spreader.
