Opf i ndel sen angår et apparat til udtømning af høstmater i ale fra en samlebeholder med mindst én udtømningssnegl, som er anbragt ved samlebeholderens bund, og som er afdækket af en afdækningsindretning, der sammen med bunden danner mindst en 5 indløbsspalte eller indløbsåbning, og hvor høstmaterialet bliver ført til udtømningssneglen ved hjælp af mindst ét drivbart transportorgan i form af en padlevalse.The invention relates to an apparatus for discharging harvesting feeds into ale from a collecting container having at least one discharge auger disposed at the bottom of the collecting container, which is covered by a cover device which together with the bottom forms at least one inlet slot or inlet opening, and wherein the harvesting material is fed to the discharge auger by means of at least one propellant transport means in the form of a paddle roller.

Fra østtysk patentskrift nr. 134.908 kendes en samlebeholder 10 til en mejetærsker, som ved samlebeholderens bund har en udtømningssnegl, der er afdækket med en holdeindretning og en derunder liggende skrabesluffe, og hvor den tilsvarende endekant af skrabesluffen sammen med samlebeholderens bund danner en indløbsåbning. Skrabesluffen skal forhindre, at der i områ-15 det ved indløbstværsnittet dannes en bro af høstmateriale, som ville forhindre en yderligere tilflydning af høstmaterialet til udtømningssneglen. En sådan konstruktion er dyr, især da skrabesluffen også må strække sig over hele bredden af samlebeholderens bund. Endvidere er der fare for, at høstmaterialet 20 bliver beskadiget, da det kan sætte sig fast imellem drivorganerne, f.eks. i skrabesluffens kædehjul. Endelig forhindrer skrabesluffen ikke, at der under udtømningssneglens stilstand samler sig temmelig meget høstmateriale i dennes indløbsområde, så at startmomentet for udtømningssneglen er relativt 25 stort.From East German patent specification No. 134.908, a collector 10 is known to a combine which has at the bottom of the container a discharge auger, which is covered with a holding device and an underlying scraper loop, and the corresponding end edge of the scraping loop together with the bottom of the collector container forms an inlet opening. The scraper loop must prevent a bridge of harvesting material from forming in the area at the inlet cross-section which would prevent a further inflow of the harvesting material to the discharge auger. Such a construction is expensive, especially since the scraper loop must also extend over the entire width of the bottom of the collector. Furthermore, there is a danger that the harvesting material 20 will be damaged as it may get stuck between the driving means, e.g. in the sprocket loop sprocket. Finally, the scraper loop does not prevent during the discharge of the discharge auger from accumulating quite a lot of harvesting material in its inlet area, so that the starting torque of the discharge auger is relatively large.

Over for dette er formålet med opfindelsen at holde startmomentet for udtømningssneglen så lille som muligt med enkle konstruktive midler.To this end, the object of the invention is to keep the starting torque of the discharge auger as small as possible with simple constructive means.

Dette formål opnås med apparatet ifølge opfindelsen, der er ejendommeligt ved, at padlevalsen er anbragt i området ved indløbsåbningen. Herved sikres det nemlig, at startmomentet for udtømningssneglen kan holdes lille, idet der kun kan samle 35 sig lidt høstmateriale i indtrækningsområdet for udtømnings sneglen. Herved undgås en overbelastning af drivmekanismen.This object is achieved with the apparatus according to the invention, which is characterized in that the paddle roller is arranged in the area at the inlet opening. In this way, it is ensured that the starting torque of the discharge auger can be kept low, since only a small amount of harvesting material can accumulate in the withdrawal area of the discharge auger. This avoids an overload of the drive mechanism.

Dette er især en fordel i de tilfælde, hvor høstmaterialet har en høj fugtighedsgrad, og den indre friktrionsmodstand i høst- materialet er stor. Anvendelsen af padlevalsen sikrer også, at der i området ved indløbsåbningen ikke dannes nogen bro af høstmateriale, som ville kunne forhindre, at yderligere høst-5 materiale blev ført til udtømningssneglen. Med henblik på bgså uden videre at kunne starte udtømningssneglen er det en fordel, at indløbsåbningen til udtømningssneglen kan lukkes ved padlevalsens stilstand. Derved kan samlebeholderen uden videre fyldes med høstmateriale, uden at dette samler sig i indløb-sområdet for udtømningssneglen.This is particularly advantageous in cases where the harvesting material has a high degree of moisture and the internal frictional resistance of the harvesting material is high. The use of the paddle roller also ensures that no bridge of harvesting material is formed in the area at the inlet opening, which would prevent further harvesting material from being fed to the discharge auger. In order to be able to start the discharge auger without further delay, it is advantageous that the inlet opening for the discharge auger can be closed at the standstill of the paddle roller. In this way, the collecting container can be filled with harvesting material without being collected in the discharge area of the discharge auger.

Ifølge opfindelsen er det endvidere en fordel, at padlevalsens længdeakse er parallel med udtømningssneglens længdeakse, og at padlevalsen er anbragt således foran eller bag ved indløbs-15 åbningen, at det effektive indløbstværsnit i indløbsåbningen er væsentligt mindre ved padlevalsens stilstand end under drift. Padlevalsen kan f.eks. med fordel have flere på en aksel anbragte transportblade, hvor den ende af transportbladene, der ligger nærmest bunden i samlebeholderen, sammen med 20 beholderens bund danner den mindste indføringsåbning. Derved kan indløbstværsnittet i indløbsåbningen til udtømningssneglen på enkel måde formindskes ved anvendelse af større transportblade på padlevalsen og forøges ved anvendelse af mindre transportblade. Ved roterende padlevalse medvirker det mellem 25 transportbladene dannede kammer til optagelse af høstmaterialerne til at forøge indløbstværsnittet. Padlevalsen kan drives af en særlig drivmekanisme eller også, ved passende hældning af bunden i samlebeholderen, alene ved hjælp af høstmaterialets egenvægt. I begge tilfælde er det en fordel, hvis padlevalsen 30 ved igangsætningen kan afsikres ved hjælp af en passende åbningsmekanisme, så padlevalsen kun aktiveres efter at udtømningssneglen er startet.Further, according to the invention, it is an advantage that the longitudinal axis of the paddle roll is parallel to the longitudinal axis of the discharge auger and that the paddle roll is arranged in front of or behind the inlet opening so that the effective inlet cross-section in the inlet opening is substantially smaller at the standstill of the paddle roll than during operation. The paddle roller can e.g. advantageously having a plurality of transport blades arranged on a shaft, the end of the transport blades closest to the bottom of the collecting container together with the bottom of the container forming the smallest opening opening. Thereby, the inlet cross-section of the discharge port inlet port can be simply reduced by the use of larger conveyor blades on the paddle roller and increased by the use of smaller conveyor blades. In the case of rotating paddle rollers, the chamber formed between the transport blades contributes to receiving the harvesting materials to increase the inlet cross section. The paddle roller can be driven by a special drive mechanism or, by appropriate inclination of the bottom of the collecting container, solely by the weight of the harvesting material. In both cases, it is advantageous if the paddle roller 30 can be secured at start-up by an appropriate opening mechanism so that the paddle roller is activated only after the discharge screw has been started.

Ifølge et yderligere træk ved opfindelsen er det en fordel, at 35 afdækningsindretningen og/eller padlevalsens aksel er anbragt indstillelig i retningen hen imod og bort fra bunden i samle- 3According to a further feature of the invention, it is an advantage that the cover device and / or the shaft of the paddle roller is arranged adjustably in the direction towards and away from the bottom of the assembly.

beholderen. Herved lader udtømningssneglen sig belaste forskellig stærkt med høstmateriale, alt efter hvilken stilling padlevalsen henholdsvis afdækningsindretningen indtager i forhold til bunden. For at opnå en yderligere forøgelse af volu-5 menstrømmen i høstmaterialet kan også omdrejningstallet for drivmekanismen til fremdrivning af padlevalsen forøges. I den forbindelse kan padlevalsen og udtømningssneglen med fordel drives i fællesskab fra én og samme drivmekanisme. Diameteren af padlevalsens omdrejningscirkel kan med fordel være større 10 end gennemgangstværsnittet i indløbsåbningen. Desuden er det en fordel, at padlevalsen er anbragt oven over en skråt forløbende bunddel af samlebeholderens bund. Ved anvendelsen af en relativt stor padlevalse opnår man også et ret stort kammervolumen mellem de enkelte transportblade i padlevalsen, så at IS der sikres en optimal forsyning af udtømningssneglen med høstmateriale.container. In this way, the discharge auger is subjected to a different load with harvesting material, depending on the position of the paddle roller and the cover device respectively relative to the bottom. In order to further increase the volume flow in the harvesting material, the speed of the drive mechanism for propelling the paddle roller can also be increased. In this connection, the paddle roller and the discharge auger can advantageously be operated jointly from one and the same drive mechanism. The diameter of the paddle roller rotation circle can advantageously be greater than the cross-section of the inlet opening. In addition, it is advantageous that the paddle roller is positioned above a sloping bottom portion of the bottom of the collecting container. When using a relatively large paddle roller, a fairly large chamber volume is also obtained between the individual transport blades in the paddle roller, so that IS ensures an optimal supply of the discharge auger with harvesting material.

Med henblik på at formindske vedhængningsfriktionen mellem høstmaterialet og bunden af samlebeholderen kan det ifølge op-20 findelsen endvidere være en fordel, såfremt der oven over den skråt forløbende bunddel af samlebeholderen findes talrige ved siden af hinanden anbragte padlevalser, og der mellem afdækningsindretningen og samlebeholderens bund er dannet to over for hinanden liggende indløbsåbninger, til hver af hvilke der 25 hører en eller flere padlevalser.In addition, in order to reduce the adhesion friction between the harvesting material and the bottom of the collecting container, it can be advantageous if there are numerous adjacent paddle rollers located adjacent to each other and between the covering device and the collecting container bottom. two opposite inlet openings are formed, each of which has one or more paddle rollers.

På tegningen er skematisk vist et udførelseseksempel for en indretning til udtømning af en samlebeholder ifølge opfindelsen. På tegningen er med 2 betegnet en samlebeholder, som kan 30 indbygges i en på tegningen ikke vist mejetærsker. Det er dog også muligt f.eks. at anvende samlebeholderen 2 i et køretøj, som tjener til optagelse henholdsvis til transport af styrtgods. Samlebeholderen 2 har to skråt forløbende bunddele 4, som begrænses af en forvæg 6 og en ikke vist bagvæg og to på 35 tegningen ikke viste sidevægge. Bunddelene 4 danner et snegltrug 10, som tjener til optagelse af en udtømningssnegl 12, der strækker sig over samlebeholderens 2 samlede bredde, og 4BRIEF DESCRIPTION OF THE DRAWINGS An embodiment of a device for discharging a collector according to the invention is schematically shown in the drawing. In the drawing, a collection container is indicated by 2, which can be built into a combine harvester not shown in the drawing.

som er anbragt på en aksel 14. Akselen 14 er drejeligt lejret i sidevæggene og har i sin ene ende et kædehjul 16, omkring hvilket er ført en drivkæde 18, som står i forbindelse med et drivhjul 20, der bliver drevet af en på tegningen ikke vist 5 drivmekanisme. Til udtømningssneglen 12 slutter sig ved enden en på tegningen ikke vist udbringsningstransportsnegl, ved hjælp af hvilken høstmaterialet kan afgives i et køretøj.mounted on a shaft 14. The shaft 14 is pivotally mounted in the side walls and has at one end a sprocket 16 around which is driven a sprocket 18 which communicates with a sprocket 20 driven by one in the drawing. shown 5 drive mechanism. To the discharge auger 12 is joined at the end a discharge auger not shown in the drawing, by means of which the harvesting material can be delivered in a vehicle.

Oven over udtømningssneglen 12 befinder der sig en tagformet 10 afdækningsindretning 22, som kan bestå af en tyndvægget blikplade, og som i den ene ende er fast forbundet med en holder 24. Holderen 24 har i sine nedre ender en flig 26, som ved hjælp af skruebolte 28 er forbundet med bunden 4 i samlebehol-deren 2. I samlebeholderen 2 kan der findes flere ved siden af 15 hinanden anbragte holdere 24, som tjener til optagelse hen holdsvis afstivning af afdækningsindretningen 22. Afdækningsindretningen 22 består af en første afdækningsdel 30, der forløber parallelt med den ydre overflade af holderen 24, og til hvilken der slutter sig en anden fritstående tagformet afdæk-20 ningsdel 32, hvis frie ydre ende 34 med den højre bunddel 4 i samlebeholderen 2 danner en indløbsåbning. Afdækningsindretningen 22 har i sin ende en flange 38, som er fast forbundet med de på tegningen ikke viste sidevægge i samlebeholderen 2. 1 2 3 4 5 6 7 8 9 10 11 På holderen 24 er der endvidere ved hjælp af skruebolte 42 af 2 tageligt fastgjort et todelt træleje 40. Trælejet 40 tjener 3 til optagelse af en aksel 44, på hvilken der er anbragt tal 4 rige transportblade 46 med indbyrdes afstand. Akselen 44 dan 5 ner sammen med transportbladene 46 en padlevalse 48, som er 6 anbragt noget bag ved indløbsåbningen 36 neden under afdæk 7 nings ind retningen 22. Ved enden af akselen 44 befinder sig et 8 kædehjul 50, og et yderligere kædehjul 52 er anbragt på akse 9 len 14. Foran indløbsåbningen 36 findes en holder 54, som tje 10 ner til optagelse af et vendehjul 56. Holderen 54 er ved hjælp 11 af skruebolte 58 fast forbundet med en sidevæg i samlebeholderen 2. Holderen 54 er forsynet med en langsgående slids' 60, der tjener til optagelse af en bolt 62, som er indstilleligt 5Above the discharge auger 12 there is a roof-shaped 10 cover device 22 which may consist of a thin-walled sheet of plate, which at one end is fixedly attached to a holder 24. The holder 24 has at its lower ends a tab 26 which screw bolts 28 are connected to the bottom 4 of the collecting container 2. In the collecting container 2 there can be found several adjacent holders 24 which serve to receive or stiffen the cover device 22 respectively. The cover device 22 consists of a first cover portion 30 which extends parallel to the outer surface of the holder 24, to which joins another freestanding roof-shaped cover portion 32, the free outer end of which 34 with the right bottom portion 4 of the collecting container 2 forms an inlet opening. The cover device 22 has at its end a flange 38 which is firmly connected to the sidewalls not shown in the drawing in the collecting container 2. 1 2 3 4 5 6 7 8 9 10 11 On the holder 24, screw bolts 42 of 2 are also removable attached a two-piece wooden bearing 40. The wooden bed 40 serves 3 to receive a shaft 44, on which numbers 4 are richly spaced transporting leaves 46. The shaft 44 forms, together with the conveyor blades 46, a paddle roller 48 which is positioned slightly behind the inlet opening 36 below the cover 7 in the direction 22. At the end of the shaft 44 there is an 8 sprocket 50 and an additional sprocket 52 is arranged on the shaft 9, 14. In front of the inlet opening 36 is a holder 54, which serves to receive a turning wheel 56. The holder 54 is fixedly fixed by means of 11 screws 58 to a side wall of the collecting container 2. The holder 54 is provided with a longitudinal slot 60 which serves to receive a bolt 62 which is adjustable 5

lejret i den langsgående slids 60. Bolten 62 kan være fastgjort i forskellige stillinger i den langsgående slids 60. Hertil tjener på tegningen ikke viste møtrikker. På bolten 62 er vendehjulet 56 lejret drejeligt, og omkring det er ført en 5 drivkæde 64, som endvidere er ført omkring kædehjulet 52. Den udvendige periferi af drivkæden 64 står endvidere i drivforbindelse med kædehjulet 50. Derved lader padlevalsen 48 sig drive i urviserens retning, når udtømningssneglen 12 drives i modsat retning. Udtømningssneglen 12 og padlevalsen 48 drives 10 altså begge af kæden 18.the bearing 62 in the longitudinal slot 60. The bolt 62 may be fixed in different positions in the longitudinal slot 60. For this purpose nuts not shown in the drawing serve. On the bolt 62, the turning wheel 56 is mounted pivotally, and around it is driven a drive chain 64, which is further passed around the sprocket 52. The outer periphery of the drive chain 64 is also in driving communication with the sprocket 50. Thus, the paddle roller 48 is driven in the clockwise direction. when the discharge auger 12 is driven in the opposite direction. Thus, the discharge auger 12 and the paddle roller 48 are both driven by the chain 18.

Padlevalsen 48 er drejeligt lejret i trælejet 40 og kan forskydes langs overfladen af holderen 24, så at i ndløbsåbn i ngen 36 mellem den yderste ende af transportbladene 46 og overfla-15 den af bunden 4 kan ændres. Ligeledes er det muligt at forbinde afdækningsdelen 32 leddelt med afdækningsdelen 30 og at forskyde den frie ende 34 af afdækningsindretningen 22 i forhold til bunden 4 i samlebeholderen 2. Dermed lader det samlede tværsnit af indløbsåbningen 36 sig ligeledes variere.The paddle roller 48 is pivotally mounted in the wooden bed 40 and can be displaced along the surface of the holder 24 so that in the inlet aperture at the end 36 between the outermost end of the transport blades 46 and the surface of the bottom 4 can be changed. Likewise, it is possible to connect the cover portion 32 articulated to the cover portion 30 and to displace the free end 34 of the cover device 22 relative to the bottom 4 of the receptacle 2. Thus, the overall cross-section of the inlet opening 36 also varies.

Ved fyldning af samlebeholderen 2 kan høstmaterialet kun samles i den nedre halvdel af snegltruget 10, da transportbladene 46 på padlevalsen 48 forhindrer en yderligere opsamling af høstmateriale i snegltruget 10. Startmomentet for udtømnings-25 sneglen 12 er derfor relativt lille, da det i samlebeholderen 2 værende høstmateriale ikke trykker med sin samlede vægt på udtømningssneglen 12, idet en stor del af høstmaterialet tillige bæres af afdækningsindretningen 22. Ved start af udtømningssneglen 12 startes samtidig padlevalsen 48, så at udtøm-30 ningssneglen 12 nu med en vis forsinkelse belastes med mere høstmateriale, således at fyldningsgraden for udtømningssneglen øges jævnt. Udtømningssneglens 12 fyldningsgrad afhænger af det samlede gennemstrømningstværsnit i indløbsåbningen 36, af omdrejningstallet for padlevalsen 48 samt af de af trans-35 portbladene 46 dannede transportkamre 66.When filling the collecting container 2, the harvesting material can only be collected in the lower half of the auger 10, since the transport blades 46 on the paddle roller 48 prevent further collection of harvesting material in the auger 10. The starting torque for the discharge auger 12 is therefore relatively small, since in the collecting container 2 the harvesting material does not press with its total weight on the discharge auger 12, a large part of the harvesting material being also carried by the covering device 22. At the start of the discharge auger 12, the paddle roller 48 is simultaneously started, so that the discharge auger 12 is now loaded with a certain delay for more harvesting material. , so that the degree of filling of the discharge auger increases evenly. The degree of filling of the discharge auger 12 depends on the overall flow cross-section of the inlet opening 36, the speed of the paddle roller 48 and the transport chambers 66 formed by the conveyor blades 46.

Når hældningen i samlebeholderens bund 4 har en passende størrelse, kan padlevalsen 48 også drives alene ved høstmateria-When the slope in the bottom 4 of the hopper is of a suitable size, the paddle roller 48 can also be operated alone by harvesting material.
