Description
Den foreliggende oppfinnelse vedrører en fjæringsanordning for valseparet i en knuserapparatur, hvor i hvert fall den ene knuservalse er montert i en svingarm som er opplagret i apparaturstammen på slik måte, at spalten mellom valsene åpnes under innvirkning av en uknusbar gjenstand som inne-klemmes . The present invention relates to a suspension device for the pair of rollers in a crusher apparatus, where at least one crusher roller is mounted in a swing arm which is stored in the apparatus trunk in such a way that the gap between the rollers is opened under the influence of an unbreakable object which is clamped inside.
I knuserapparaturer må spalten mellom valsene være slik anordnet, at den utvides elastisk hvis f.eks. en uknusbar sten eller et seigt trestykke havner mellom valsene. Dette krav på elastisitet er vanligvis blitt imøtekommet på den måte, In crushing equipment, the gap between the rollers must be arranged in such a way that it expands elastically if, e.g. an unbreakable stone or a tough piece of wood ends up between the rollers. This demand for elasticity has usually been accommodated in the way,
at den ene valse er opplagret i en f j ærbe las tet svingarrn, hvor-ved valsene tvinges mot hverandre. Spalten åpnes når en uknusbar gjenstand føres inn mellom valsene. Samtidig øker den trykk-utøvende fjærkraft. For at gjenstanden med sikkerhet skal kunne passere gjennom spalten, må kreftene som holder slike valser i rotasjon, være beregnet atskillig høyere enn det som ville kreves for selve knusingen. that one roller is stored in a spring-loaded swivel arm, whereby the rollers are forced against each other. The gap opens when an unbreakable object is introduced between the rollers. At the same time, it increases the pressure-exerting spring force. In order for the object to be able to safely pass through the gap, the forces that keep such rollers in rotation must be calculated to be considerably higher than what would be required for the crushing itself.
Hensikten med den foreliggende.oppfinnelse er å frem-bringe en fjæringsanordning av ny type. En slik fjæringsanordning ifølge oppfinnelsen kjennetegnes ved at den omfatter to leddarmer som er montert nær ved og i flukt med hverandre, The purpose of the present invention is to produce a suspension device of a new type. Such a suspension device according to the invention is characterized by the fact that it comprises two articulated arms which are mounted close to and flush with each other,
hvor armparets ene ende er opplagret i knuserapparaturstammen og den annen ende i svingarmen, og at armparet påvirkes av en kraft som er motsatt rettet i forhold til de krefter som vil skille valsene fra hverandre. where one end of the pair of arms is stored in the crushing equipment stem and the other end in the swing arm, and that the pair of arms is affected by a force that is oppositely directed in relation to the forces that will separate the rollers from each other.
Det er ifølge oppfinnelsen frembrakt en fjæringsanordning som atskiller seg fra kjente anordninger av liknende type, According to the invention, a suspension device has been produced which differs from known devices of a similar type,
ved at fjæringsanordningens trykkraft avtar når spalten mellom valsene utvides, slik at en uknusbar gjenstand som er havnet mellom valsene, vil passere hurtigere og lettere gjennom spalten. in that the compression force of the suspension device decreases when the gap between the rollers widens, so that an unbreakable object that has ended up between the rollers will pass through the gap faster and easier.
En fordelaktig utførelsesform av oppfinnelsen kjennetegnes ved at den ene leddarrn er anordnet som en motvekt som tilstreber å lukke spalten mellom valsene. Et eget, kraftig dimensjonert fjærsystem blir derved overflødig. An advantageous embodiment of the invention is characterized by the fact that one joint is arranged as a counterweight which tends to close the gap between the rollers. A separate, heavily dimensioned spring system is therefore redundant.
En andre utførelsesform av oppfinnelsen kjennetegnes ved' at leddarmene påvirkes av en fjærkraft. En strekkfjær som er forbundet med leddarmene, tjener utelukkende som hjelpe-middel i tilfelle av at kraften fra motvekten viser seg -util-strekkelig. Fjæren akselererer returbevegelsen. A second embodiment of the invention is characterized by the fact that the joint arms are affected by a spring force. A tension spring which is connected to the articulated arms serves exclusively as an aid in the event that the force from the counterweight proves insufficient. The spring accelerates the return movement.
En tredje utførelsesform av oppfinnelsen kjennetegnes ved at fjærkraften frembringes av en strekkfjær som er innmontert i motvekten og hvis ene ende er fastgjort til knuserapparaturstammen. Fjæren ligger således beskyttet inne i motvekten, slik at ulykkesrisikoen minsker. A third embodiment of the invention is characterized by the fact that the spring force is produced by a tension spring which is installed in the counterweight and one end of which is attached to the crushing apparatus stem. The spring is thus protected inside the counterweight, so that the risk of accidents is reduced.
En ytterligere utførelsesform av oppfinnelsen kjennetegnes ved at vinkelen mellom leddarmenes dreiepunkter i hvilestillingen utgjør ca. 160°. For å utvide spalten mellom valsene vil det i et slikt tilfelle kreves en kraft som er ca. syv ganger større enn kraften som virker mot leddarmene. Idet spalten utvides minsker vinkelen mellom dreiepunktene, og samtidig forandres forholdet mellom kreftene, slik at spalten åpnes lettere og hurtigere. A further embodiment of the invention is characterized by the fact that the angle between the pivot points of the joint arms in the rest position amounts to approx. 160°. To widen the gap between the rollers in such a case, a force of approx. seven times greater than the force acting against the articulated arms. As the gap widens, the angle between the pivot points decreases, and at the same time the relationship between the forces changes, so that the gap opens more easily and faster.
Oppfinnelsen vil bli nærmere beskrevet i det etterfølgende under henvisning til de medfølgende tegninger, hvori: The invention will be described in more detail below with reference to the accompanying drawings, in which:
Fig. 1 viser et sideriss av en knuserapparatur.Fig. 1 shows a side view of a crushing apparatus.
Fig. 2 viser et forstørret riss av knuserapparaturens fjæringsanordning. Fig. 2 shows an enlarged view of the crushing device's suspension device.
Den høyre knuservalse 1 i knuserapparaturen er montertThe right crushing roller 1 in the crushing equipment is installed
i en svingarm 3 som er opplagret i apparaturstammen, slik at spalten mellom valsene 1 og 4 utvides når en uknusbar gjenstand innklemmes mellom valsene. Fjæringsanordningen omfatter to leddarmer 5 og 6 som er opplagret nær ved og i flukt med hverandre. Den ene ende 7 av armparet 5 og 6 er opplagret ved knuserapparaturstammen 2 og den annen ende 8 ved svingarmen 3. Armparet 5 og 6 påvirkes av en kraft F 2 som er motsatt rettet i forhold til den kraft F, som tilstreber å skille valsene 1 og 4 fra hverandre. Den ene leddarrn 6 består av en motvekt med tendens til å lukke spalten mellom valsene 1 og 4. Leddarmene 5 og 6 påvirkes dessuten av en fjærkraft som frembringes av en strekkfjær 9 som er innmontert i motvekten 6 in a swing arm 3 which is stored in the apparatus trunk, so that the gap between the rollers 1 and 4 widens when an unbreakable object is sandwiched between the rollers. The suspension device comprises two joint arms 5 and 6 which are stored close to and flush with each other. One end 7 of the pair of arms 5 and 6 is supported by the crushing equipment stem 2 and the other end 8 by the swing arm 3. The pair of arms 5 and 6 is affected by a force F 2 which is oppositely directed in relation to the force F, which tends to separate the rollers 1 and 4 apart. The one link arm 6 consists of a counterweight with a tendency to close the gap between the rollers 1 and 4. The link arms 5 and 6 are also affected by a spring force produced by a tension spring 9 which is installed in the counterweight 6
og hvis ene ende er fastgjort til knuserapparaturstammen 2. Vinkelen som avgrenses av leddarmenes 5 og 6 dreiepunkter 10, 11 og 12 utgjør ca. 160°, motsvarende hvilestillingen, and one end of which is attached to the crushing apparatus stem 2. The angle bounded by the pivot points 10, 11 and 12 of the joint arms 5 and 6 amounts to approx. 160°, corresponding to the rest position,
og avtar eksempelvis til vinkelen i fig. 2. Når vinkelen avtar, vil også kraften mellom valsene 1 og 4 minske slik at den uknusbare gjenstand kan passere lettere og hurtigere gjennom spalten. and decreases, for example, to the angle in fig. 2. When the angle decreases, the force between rollers 1 and 4 will also decrease so that the unbreakable object can pass more easily and faster through the slot.
Det vil være åpenbart for den fagkyndige at oppfinnelsens forskjellige utførelsesformer kan varieres innenfor rammen av de etterfølgende krav. It will be obvious to the person skilled in the art that the various embodiments of the invention can be varied within the scope of the following claims.
