Opfindelsen angår et spredearrangement til spredning af en blanding af granuleret materiale, fortrinsvis salt, og en væske, fortrinsvis vand eller en opløsning af salt og vand, bestående af en tragt, der er fastgjort til et køretøj og fra et doseringsorgan på køretøjet leder granuleret materiale ned til en roterbar spredetallerken ved den nederste del af 5 tragten.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a spreading arrangement for spreading a mixture of granulated material, preferably salt, and a liquid, preferably water or a solution of salt and water, consisting of a hopper attached to a vehicle and from a metering device to the vehicle conducting granulated material. down to a rotatable spreading plate at the bottom of the funnel.
Der er flere fordele ved at anvende en blanding af salt og vand i stedet for salt alene.There are several advantages to using a mixture of salt and water instead of salt alone.
For det første opnås en saltbesparelse på ca. 23 %. For det andet er befugtet salt ikke ligeså vindfølsomt som tørt salt. For det tredje hopper det befiigtede salt ikke så meget, 10 når det under udspredningen rammer vejbanen, hvorved der opnås en mere nøjagtig positionering. For det fjerde bliver det udspredte befiigtede salt liggende på vejen ved efterfølgende trafik. Det udspredte materiale er således ikke så følsomt overfor efterfølgende trafik.First, a salt saving of approx. 23%. Secondly, wetted salt is not as wind sensitive as dry salt. Third, the moistened salt does not jump much, 10 when it hits the roadway during spreading, thereby achieving a more accurate positioning. Fourth, the scattered moistened salt is left on the road by subsequent traffic. Thus, the scattered material is not as sensitive to subsequent traffic.
15 Der kendes forskellige spredemekanismer til spredning af en blanding af salt og vand. Sammenblandingen af salt og vand er imidlertid ikke tilstrækkelig effektiv.15 Various spreading mechanisms are known for spreading a mixture of salt and water. However, the mixing of salt and water is not sufficiently effective.
Formålet med opfindelsen er at tilvejebringe et spredearrangement, der giver en mere effektiv sammenblanding af granuleret materiale og væske.The object of the invention is to provide a dispersing arrangement which provides a more efficient mixing of granulated material and liquid.
2020
Et spredearrangement af den indledningsvis nævnte art er ifølge opfindelsen ejendommeligt ved, at der i forbindelse med spredetallerkenen er indrettet et blandingskammer, hvortil det granulerede materiale og væsken føres.According to the invention, a spreading arrangement of the kind mentioned in the introduction is characterized in that a mixing chamber is arranged in connection with the spreading plate to which the granulated material and the liquid are fed.
25 Dette blandingskammer giver en mere effektiv sammenblanding end hidtil kendt.25 This mixing chamber provides a more efficient mixing than previously known.
Fremdeles kan der ifølge opfindelsen ved siden af tragten være et organ for tilførsel af væske, idet væsketilførselsorganet fortrinsvis er placeret ved siden af tragten bagved i rotationsretningen for tilførsel af granuleret materiale.Still, according to the invention, next to the hopper there may be a means for supplying liquid, the liquid supply means being preferably located next to the hopper in the rear in the direction of rotation of supply of granulated material.

Desuden kan ifølge opfindelsen spredetallerkenen omfatte en motorkegle med en indbygget motor, fortrinsvis en hydraulikmotor, der er ført ind nedefra.In addition, according to the invention, the spreading plate may comprise a motor cone with a built-in motor, preferably a hydraulic motor introduced from below.
Endvidere kan ifølge opfindelsen hydraulikmotoren drive motorkeglen og en dermed 5 forbundet navplade i blandingskammeret.Furthermore, according to the invention, the hydraulic motor can drive the motor cone and an associated hub plate 5 in the mixing chamber.
Navpladen kan med fordel være udstyret med friktionsorganer som bevirker, at der opnås en mere ensartet udslyngning af blandingen af salt og saltvand.The hub plate may advantageously be provided with friction means which result in a more uniform discharge of the salt and saline mixture.
10 Friktionsorganeme kan med fordel udgøres af på navpladen indrettede mikservinger, der fortrinsvis har form af afviklere.Advantageously, the friction means may consist of mixing blades arranged on the hub plate, preferably in the form of unwinding.
Mikservingeme har fortrinsvis en højde på maksimalt 4 mm.The mixer wings preferably have a height of maximum 4 mm.
15 Endvidere kan ifølge opfindelsen blandingskammeret have en runding i bunden. Derved sikres, at materialet føres op ad kammervæggen og derefter falder ned på mikser-vingerne på navpladen.Furthermore, according to the invention, the mixing chamber may have a rounding at the bottom. This ensures that the material is led up the chamber wall and then falls onto the mixer blades on the hub plate.
Blandingskammeret kan med fordel have en indad skrående eller indad krummet væg, 20 idet materialet derved falder tilbage på mikservingeme i stedet for at blive slynget ud af blandingskammeret.The mixing chamber may advantageously have an inwardly inclined or inwardly curved wall, the material thereby falling back onto the mixing wings instead of being thrown out of the mixing chamber.
Mikservingeme kan med fordel strække sig ud over den fastsiddende del af kammerets bund.The mixing wings can advantageously extend beyond the fixed part of the bottom of the chamber.

Det i fig. 1 viste spredearrangement ifølge opfindelsen til anbringelse på et køretøj, så-25 som en lastbil, består af en teleskopisk tragt 1, der fra et elektronisk styret doseringsaggregat på køretøjet leder granuleret materiale, såsom salt til en spredetallerken 5. Spredetallerken 5 er via en konsol, der er fastgjort til tragten 1 ophængt ved den nederste del af tragten 1.1 forbindelse med den roterbare spredetallerken 5 er der indrettet et relativt fastsiddende hus, der foroven har et dæksel 4 med en forholdsvis stor åbning 4a 30 for tilførsel af hhv. granuleret materiale, såsom salt og væske, såsom saltvand, idet der ved siden af tragten 1 er et rør la for tilførsel af væsken. I bunden af huset er der en DK 176222 B1 4 navplade 2, der er fast forbundet med spredeskiven 5 og roterer med denne - se fig. 2. Navpladen 2 er udstyret med friktionsorganer i form af afviklerformede vinger 2a af en højde på fortrinsvis 4mm.The FIG. 1, according to the invention for mounting on a vehicle, such as a truck, consists of a telescopic funnel 1 which conducts granulated material from an electronically controlled dosing assembly on the vehicle such as salt to a spreading plate 5. The spreading plate 5 is via a bracket. which is attached to the hopper 1 suspended at the lower part of the hopper 1.1 in connection with the rotatable spreading plate 5, a relatively fixed housing is provided which has a cover 4 at the top with a relatively large opening 4a 30 for supplying respectively. granulated material such as salt and liquid, such as saline, there being next to the hopper 1 a tube 1a for supplying the liquid. At the bottom of the housing there is a DK 176222 B1 4 hub plate 2 which is firmly connected to the spreading disc 5 and rotates therewith - see fig. 2. The hub plate 2 is provided with friction means in the form of unwinding blades 2a of a height of preferably 4mm.
5 Spredearrangementet står i forbindelse med en beholder 11 for afgivelse af granuleret materiale, såsom salt, såvel som en beholder 12 for afgivelse af væske, såsom saltvand - se fig. 6. Fig. 8 viser beholderen 11 for afgivelse af salt, idet der ved bunden af beholderen 11 er et befordringsorgan i form af en snegl 13 for fremføring af saltet mod den ende af beholderen 11, hvor spredearrangementet er placeret. Såvel afgivelse af salt, 10 som afgivelse af saltvand styres elektronisk ved hjælp af det i fig. 9 viste styrekredsløb, som vil blive beskrevet i det følgende.The spreader arrangement communicates with a container 11 for dispensing granulated material such as salt, as well as a container 12 for dispensing liquid such as saline - see FIG. 6. FIG. 8 shows the container 11 for dispensing salt, there being at the bottom of the container 11 a conveyor means in the form of a auger 13 for conveying the salt towards the end of the container 11 where the spreading arrangement is located. The release of salt, as well as the release of saline, is controlled electronically by the means shown in FIG. 9, which will be described below.
Virkemåden af spredearrangementet er som følger: 15 En hydraulikmotor - se fig. 2 og 3 - der er ført ind nedefra, driver en motorkegle, der står i forbindelse med navpladen 2 og spredeskiven 5 og driver disse rundt. Blandingskammeret og det dertil hørende dæksel 4 er imidlertid stillestående under motorens rotation.The operation of the spreading arrangement is as follows: 15 A hydraulic motor - see fig. 2 and 3 - inserted from below, drive a motor cone which communicates with the hub plate 2 and the spreading disc 5 and drives these around. However, the mixing chamber and associated cover 4 are stationary during engine rotation.
20 Blandingskammeret er lejret koncentrisk i forhold til spredeskiven 5.The mixing chamber is stored concentrically relative to the spreading disc 5.
Salt og saltvand ledes nu til blandingskammeret via den forholdsvise store åbning 4a i dækslet 4 til blandingskammeret og befordres af mikservingeme 2a på den roterende navplade 2 ud til blandingskammerets væg 7. Saltet og saltvandet opnår en så høj ha-25 stighed ud mod væggen 7, at det slynges op ad væggen 7 og igen falder ned på mikser-vingerne 2a - se fig. 5. Herefter befordres saltet og saltvandet igen ud til mikserkammerets væg 7 og følger denne, indtil blandingen når en åbning 8 i væggen 7 og slynges ud derfra.Salt and saline are now fed to the mixing chamber via the relatively large opening 4a of the mixing chamber cover 4 and conveyed by the mixing wings 2a of the rotating hub plate 2 to the mixing chamber wall 7. The salt and salt water achieve such a high velocity against the wall 7, that it is thrown up the wall 7 and again falls on the mixer wings 2a - see fig. 5. Then the salt and brine are again carried out to the mixer chamber wall 7 and followed until the mixture reaches an opening 8 in the wall 7 and is thrown out from there.
DK 176222 B1 5DK 176222 B1 5
Blandingskammeret har en indad skrånende eller indad krum væg 7 - se fig. 5 - idet man derved sikrer, at materialet falder tilbage på mikservingeme 2a inden det slynges ud gennem den nævnte åbning 8 i væggen 7.The mixing chamber has an inwardly sloping or inwardly curved wall 7 - see fig. 5 - thereby ensuring that the material falls back onto the mixing wings 2a before being ejected through said opening 8 in the wall 7.
5 Der er desuden en runding i bunden af blandingskammeret ved overgangen mellem navpladen 2 og den indad skrånende væg 7. Derved bliver blandingskammeret forholdsvis tæt samtidigt med at materialet lettere vil kunne slynges op ad den indad skrånende væg 7. Derved sker der en mere effektiv blanding af salt og saltvand inden blandingen slynges ud gennem åbningen 8 - se fig. 4 der viser blandingskammeret uden 10 dæksel.In addition, there is a rounding at the bottom of the mixing chamber at the transition between the hub plate 2 and the inwardly sloping wall 7. This makes the mixing chamber relatively dense while the material can be more easily thrown up the inwardly sloping wall 7. This results in a more efficient mixing. of salt and brine before the mixture is thrown out through the aperture 8 - see fig. 4 showing the mixing chamber without 10 cover.
Til opnåelse af en tilstrækkelig effektiv blanding er det væsentligt, at væsketilførslen sker inden salttilførslen.In order to obtain a sufficiently effective mixture, it is essential that the liquid is supplied before the salt application.
15 Sammenblandingen af salt og saltvand sker på flere forskellige måder: 1. Saltet rammer det allerede tilførte saltvand i blandingskammeret, idet det rammer navpladen 2 og mikservingeme 2a (saltvandet er tilført kort tid inden saltet tilføres).The mixing of salt and saline takes place in several different ways: 1. The salt hits the already supplied salt water in the mixing chamber, hitting the hub plate 2 and the mixing wings 2a (the salt water is supplied shortly before the salt is supplied).
20 2. Saltet og saltvandet blandes ved, at mikservingeme 2a som følge af friktionen ik ke befordrer alt saltet og alt saltvandet ud til væggen 7 med det samme. Der sker derved en vis omrøring ved at noget af saltet, og saltvandet ryger over mikservingeme 2a, inden det når kammerets væg 7.2. The salt and salt water are mixed by the mixing wings 2a due to the friction not conveying all the salt and all the salt water to the wall 7 immediately. Thereby, there is some stirring by some of the salt, and the salt water over the mixing wings 2a before it reaches the wall of the chamber 7.
25 3. Anslaget mod kammerets væg 7 giver en vis blanding.25 3. The impact on the wall 7 of the chamber gives some mixing.
4. Saltet og saltvandet falder igen ned på mikservingeme 2a og navpladen 2, hvilket giver en yderligere blanding.4. The salt and salt water again fall onto the mixing wings 2a and the hub plate 2, providing a further mixture.
30 5. Saltet og saltvandet befordres langs kammerets væg 7, hvilket giver en yderligere blanding.5. The salt and brine are conveyed along the wall 7 of the chamber to provide a further mixture.
DK 176222 B1 6 6. Saltet og saltvandet forbliver i 1/2 til 3/4 omgang inde i blandingskammeret, inden det via åbningen 8 i blandingskammerets væg 7 slynges ud på spredeskiven 5.6. The salt and brine remain in the mixing chamber for 1/2 to 3/4 time, before being thrown out onto the spreading disc 5 via the opening 8 in the mixing chamber wall 7.
5 Materialestrømmens retning og hastighed, der er tangentiel i forhold til kammervæggen 7, giver den fordel, at det materiale, der slynges ud af kammeret, har i det væsentlige samme tangentielle hastighed som vingerne på spredeskiven 5. Derved minimeres det eventuelle opsprøjt af salt og saltvand, hvorved risikoen for tilstopning af spredearran-gementet reduceres væsentligt.The direction and velocity of the material flow tangential to the chamber wall 7 gives the advantage that the material thrown out of the chamber has substantially the same tangential velocity as the blades on the spreading disc 5. This minimizes the possible splashing of salt and saline, thereby substantially reducing the risk of clogging of the spreading element.

Vingerne på den roterende spredeskive 5 er skråtstillede i forhold til lodret. Dette bevirker at materialestrømmen gradvis overskæres og slynges ned i kanterne mellem spredeskiven 5 og vingerne. Den gradvise overskæring og slyngning ned mod kanterne bevirker, at materialet udbredes langs vingerne. Dette bevirker igen, at spredebilledet 15 får en bred spredevinkel. Vingernes vinkel i forhold til vandret er ca. 45-55°. Endvidere skal der være en skarp kant mellem spredeskive 5 og vinge, idet materialeudbredelsen ellers ikke vil ske på en tilfredsstillende måde.The blades on the rotating spreading disc 5 are inclined with respect to the vertical. This causes the flow of material to be gradually cut and thrown down the edges between the spreading disc 5 and the blades. The gradual cutting and throwing down to the edges causes the material to spread along the wings. This in turn causes the spreading image 15 to have a wide spreading angle. The angle of the wings relative to the horizontal is approx. 45-55 °. Furthermore, there must be a sharp edge between spreading disc 5 and wing, otherwise the propagation of the material will not occur satisfactorily.
En asymmetriindstilling kan tilvejebringes ved at ændre positionen af åbningen 8 i 20 blandingskammerets væg 7. Dette sker ved at dreje blandingskammeret, således at positionen af åbningen 8 ændres. Ved at dreje åbningen 8 og dermed udtrædningspunktet af materialet fra blandingskammeret til vingerne på spredeskiven 5, vil man således kunne indstille spredebilledets asymmetri. Midlerne til indstillingen af blandingskam-meréts vinkelstilling kan f.eks. udgøres af en ledstangsmekanisme, der evt. kan være 25 manuelt betjent. Alternativt vil der kunne anvendes en servomotor. Når blandingskammeret drejes med uret, spredes der længere mod venstre og vice versa. Det vigtigste er dog, at der ikke sker nogen ændring af den samlede spredevinkel og den samlede spredebredde.An asymmetry setting can be provided by changing the position of the opening 8 in the wall 7 of the mixing chamber. This is done by rotating the mixing chamber so that the position of the opening 8 changes. By turning the aperture 8 and thus the point of exit of the material from the mixing chamber to the wings of the spreading disc 5, it is thus possible to adjust the asymmetry of the spreading image. The means for adjusting the angular position of the mixing chamber may e.g. is constituted by a handrail mechanism, which may. can be 25 manually operated. Alternatively, a servomotor could be used. Turning the mixing chamber clockwise spreads further to the left and vice versa. Most importantly, however, there is no change in the overall spreading angle and the overall spreading width.
30 Fig. 6 viser spredearrangementet monteret i forbindelse med en aflang V-formet beholder 11 for tilførsel af granulat, medens fig. 7 viser samme set fra siden. 1 bunden af den DK 176222 B1 7 V-formede beholder 11 er der et fremføringsorgan i form af en snegl 13, som fører granulatet til den for enden af beholderen 11 anbragte tragt 1, hvorfra det afgives til blandingskammeret. På siden af den V-formede beholder 11 sidder der en væskebeholder 12, hvorfra der samtidigt afgives væske til blandingskammeret via en slange og en 5 pumpe.FIG. 6 shows the spreading arrangement mounted in connection with an elongated V-shaped container 11 for supplying granules, while FIG. 7 shows the same from the side. At the bottom of the DK-176222 B1 7 V-shaped container 11, there is a feeder means in the form of a auger 13 which carries the granulate to the funnel 1 located at the end of the container 11, from which it is delivered to the mixing chamber. On the side of the V-shaped container 11 is a liquid container 12, from which liquid is simultaneously delivered to the mixing chamber via a hose and a pump.
Selve materialetilførslen styres elektronisk ved mellemkomst af et tachometer fastgjort til f.eks. et af baghjulene af det pågældende køretøj. Der er tale om en ijemjustering fra førerhuset af køretøjet, idet føreren indstiller spredebredde, dosering per areal enhed 10 med videre. Fig. 9 viser det elektroniske kredsløb, der er indrettet til at regulere hhv. dosering per arealenhed, spredebredde, væskepumpe og symmetriindstilling.The material supply itself is controlled electronically by the intervention of a tachometer attached to e.g. one of the rear wheels of that vehicle. This is a balance adjustment from the cab of the vehicle, with the driver setting the spread width, dosing per unit area 10, and so on. FIG. 9 shows the electronic circuit arranged to regulate respectively. dosage per unit area, spread width, fluid pump and symmetry setting.
Salttilførslen styres separat i forhold til væsketilførslen. Reguleringen skal ske ret hurtigt inden for ca. 1 sek. Reguleringen foretages ved at en indstillet set-værdi sammen-15 lignes med øjebliksværdien, og der genereres et fejlsignal, der anvendes som et tilbagekoblingssignal i en tilbagekoblingssløjfe med negativ tilbagekobling.The salt supply is controlled separately in relation to the liquid supply. The regulation must be done fairly quickly within approx. 1 sec The adjustment is made by comparing a set set value with the instantaneous value and generating an error signal used as a feedback signal in a negative feedback feedback loop.
Væsketilførslen reguleres på tilsvarende måde' ved at en indstillet set-værdi sammenlignes med øjebliksværdien, ved hvilken sammenligning der genereres et fejlsignal, der 20 anvendes som tilbagekoblingssignal i en tilbagekoblingssløjfe.The fluid supply is similarly regulated by comparing a set set value with the instantaneous value at which comparison generates an error signal used as a feedback signal in a feedback loop.
Spredebredden reguleres ved at en til spredebredden svarende set-værdi af spredeski-vens dvs. hydraulikmotorens omløbstal sammenlignes med øjebliksværdien til generering af et fejlsignal, der anvendes i en tilbagekoblingssløjfe.The spread width is regulated by a set value of the spreading disc corresponding to the spreading width ie. the hydraulic motor's turnover rate is compared to the instantaneous value for generating an error signal used in a feedback loop.
2525
Symmetripositionen kan reguleres på en tilsvarende måde ved at et til den ønskede symmetriposition svarende set-signal sammenlignes med øjebliksværdien til generering af et fejlsignal, der via et tilbagekoblingssignal anvendes til at indstille en separat servomotor, der styrer vinkelstillingen af åbningen i blandingskammerets væg 8.The position of symmetry can be regulated in a similar way by comparing a set signal corresponding to the desired position of symmetry with the instantaneous value of generating an error signal which is used via a feedback signal to set a separate servo motor which controls the angular position of the opening in the wall of the mixing chamber 8.
