Opfindelsen angår en indføder til en ballepresse af den art, som tjener til at presse en biomasse, som f.eks. halm, sammen i baller, og som omfatter et pressekammer, ét i dette anbragt pressestempel til under repeterende stempelslag at presse 5 biomassen i pressekammeret sammen til baller og et drivarrangement til under drift reciprocerende at forskyde pressestemplet. iBACKGROUND OF THE INVENTION straw, together in bales, comprising a press chamber, one in this press plunger for pressing the biomass in the press chamber together into bales during a repetitive piston stroke and a drive arrangement for displacing the press plunger reciprocally during operation. in

Biomasse har i dets naturlige løse tilstand et stort volumen i 10 forhold til dets masse. I moderne ballepresser forkomprimeres biomassen derfor før pressekammeret for derved at udnytte ballepressens kapacitet bedst muligt.Biomass, in its natural loose state, has a large volume in 10 relative to its mass. In modern baler presses, the biomass is therefore pre-compressed before the press chamber in order to make best use of the capacity of the baler.

Kørende eller trukne ballepresser er almindeligvis udstyret med 15 en indføder til successivt at opsamle biomasse og transportere denne ind i pressekammeret. Nogle af disse indfødere er desuden i stand til at forkomprimere biomassen.Moving or towed balers are generally equipped with an inverter to successively collect biomass and transport it into the press chamber. In addition, some of these natives are capable of pre-compressing the biomass.

Der kendes også indf ødere med en tragt, som fyldes med 20 biomasse, som ledes ned i et forkomprimeringskammer med et stempel til at forkomprimere biomassen og presse denne ind i pressekammeret.Also known are feeders with a hopper which is filled with 20 biomass which is fed into a pre-compression chamber with a plunger for pre-compressing the biomass and pressing it into the press chamber.

Fælles for disse indf ødere er, at de har en kompliceret og 25 kostbar konstruktion, og det er derfor formålet med opfindelsen er at anvise en indføder af den indledningsvis nævnte art, som har en enkel og driftsikker konstruktion.Common to these natives is that they have a complicated and expensive construction, and therefore the object of the invention is to provide a native of the kind mentioned in the introduction which has a simple and reliable construction.

Det nye og særegne ifølge opfindelsen, hvorved dette opnås 30 består i, at indføderen omfatter en opretstående forrådstragt med en øvre indgangsåbning og nedre afgangsåbning, mindst én slids, som er udformet i én af tragtens vægge, og som strækker sig i én fra indgangs- til afgangsåbningen gående retning, mindst én langstrakt drivtand med dimensioner, der tillader 35 tanden i hovedsagen på langs at passere ind og ud af tragten via den mindst ene slids, og en fødemekanisme til at føre 2 DK 174679 B1 tanden i cykliske bevægelser via en øvre - og nedre position inde i tragten og en nedre - og øvre position uden for tragten.The new and distinctive feature of the invention, whereby this is achieved, consists in that the feeder comprises an upright supply funnel with an upper inlet opening and lower outlet opening, at least one slot formed in one of the walls of the hopper and extending into one from the input port. to the outlet opening, at least one elongated drive tooth with dimensions allowing the 35 tooth substantially longitudinally to pass in and out of the hopper via the at least one slot, and a feeding mechanism for guiding the tooth in cyclic motions through an upper - and lower position inside the hopper and a lower and upper position outside the hopper.

Når tanden befinder sig ind i tragten og føres nedefter fra 5 dens øvre - til nedre position, påvirkes biomassen i tragten med en nedadrettet kraft. Derved forkomprimeres biomassen.When the tooth is in the funnel and is moved downward from its upper - to lower position, the biomass in the funnel is affected with a downward force. This pre-compresses the biomass.

Under pressestemplets returslag stoppes den forkomprimerede ' biomasse desuden ned i pressekammeret.In addition, during the return of the press plunger, the pre-compressed 'biomass' is stopped in the press chamber.

10 Når tanden har nået sin nedre stilling, trækkes den ud af tragten, løftes op til dens øvre stilling uden for tragten og skydes på ny ind i denne i afslutning af cyklen.10 When the tooth has reached its lower position, it is pulled out of the hopper, lifted to its upper position outside the hopper and re-inserted into it at the end of the cycle.

Disse cykler gentages fortløbende med en takt, som passer til 15 den ønskede tilførsel af biomasse til tragten og den ønskede forkomprimeringsgrad af biomassen i denne.These cycles are repeated continuously at a rate which corresponds to the desired supply of biomass to the hopper and the desired degree of pre-compression of the biomass therein.

Medens drivtanden beskriver sin nedadgående bevægelse, kan forrådstragten uden videre efterfyldes med biomasse.While the driving tooth describes its downward movement, the supply funnel can be replenished with biomass.

20 I praksis kan der med fordel være udformet flere parallelle slidser i forrådstragtens væg og indføderen have et hertil svarende antal drivtænder fastgjort på en fælles tværstang. Med flere tænder kan biomassen forkomprimeres over hele tragtens 25 tværsnit.In practice, several parallel slots may advantageously be formed in the wall of the supply funnel and the feeder having a corresponding number of drive teeth attached to a common crossbar. With multiple teeth, the biomass can be pre-compressed over the entire 25 cross-section of the funnel.

Ved en enkel og hensigtsmæssig udførelsesform kan fødemekanismen omfatte mindst én svingbart lejret fluidcylinder til via den mindst ene slids at skyde den mindst ene tand ind 30 og ud af tragten, og mindst én anden svingbart lejret fluidcylinder til at svinge den første fluidcylinder om dens i svingleje.In a simple and convenient embodiment, the feeding mechanism may comprise at least one pivotally mounted fluid cylinder for sliding the at least one tooth in and out of the hopper and at least one other pivotally mounted fluid cylinder to pivot the first fluid cylinder about its in pivot bearing. .

Opfindelsen forklares nærmere nedenfor, idet der beskrives en 35 alene eksempelvis udførelsesform under henvisning til tegningen, hvor 3 DK 174679 B1The invention is explained in more detail below, a description of an embodiment only being described with reference to the drawing, in which
