Maskine til snitning af halm.Straw cutting machine.
Frembringelsens anvendelsesområdeScope of production
Denne frembringelse angår en maskine til snitning og oplivning af halm, hvor halmen, fortrinsvis i form af halmballer, bearbejdes af en med radiære knive bestykket, roterende tromle, der drives af en gearmotor.This invention relates to a machine for cutting and grinding straw, wherein the straw, preferably in the form of straw bales, is processed by a rotary drum rotary drum driven by a gear motor.
Kendt teknikPrior art
Fra beskrivelsen til dansk brugsmodel BR 2004 00295 kendes et anlæg til automatisk strøning i stalde, især løsdriftstalde af typen med sengebåse. Anlægget er et hængebaneanlæg med en motordreven transportkasse, som er indrettet med en udfødnings- og spredemekanisme i bunden. Transportkassen er ophængt i en skinne, der strækker sig rundt i stalden, således at transportkassen ved at køre langs denne skinne passerer netop de områder af stalden, hvor der er behov for strøning. Køreskinnen er anbragt i passende højde over sengebåsene, således at transportkassen kan køre rundt i anlægget uden at være til gene for dyrene.From the description to Danish utility model BR 2004 00295, a system for automatic bedding in stables is known, in particular loose stables of the type with bed stalls. The system is a suspension rail system with a motor-driven transport box, which is equipped with a feeding and spreading mechanism at the bottom. The transport box is suspended in a rail extending around the barn, so that the transport box, passing along this rail, passes precisely those areas of the barn where bedding is needed. The guide rail is placed at an appropriate height above the bed stalls, so that the transport box can travel around the facility without disturbing the animals.
Transportkassen og den dertil hørende udfødningsmekanisme er indrettet til håndtering af snittet halm, savsmuld og lignende strømateriale i løs form. Anlægget, som arbejder fuldautomatisk efter et forud fastlagt program, er indrettet med en påfyldningsstation, hvor strømateriale påfyldes transportkassen, når denne er tom. Efter genopfyldning kører transportkassen tilbage til det sted, hvor den slap, for dér at genoptage strøarbejdet. På denne måde kan en komplet strøning af stalden gennemføres helt uden manuel indgriben uanset antallet af genopfyldningssekvenser.The conveyor box and the associated feeding mechanism are arranged for handling cut straw, sawdust and similar stream material in a loose form. The plant, which operates fully automatically according to a predetermined program, is equipped with a filling station, where flow material is filled to the transport box when it is empty. After refilling, the transport box returns to the place where it left off to resume the irrigation work. In this way, a complete littering of the barn can be carried out completely without manual intervention, regardless of the number of replenishment sequences.
Det automatiske strøningsanlæg forudsætter imidlertid strømateriale af en passende finhedsgrad for at fungere problemfrit. Især vil halm, som ikke er snittet og dermed findelt i tilstrækkelig grad, let give anledning til stop i udfødningsmekanismen og andre driftsmæssige forstyrrelser. De maskiner til oprivning og snitning af halm, der findes på markedet i dag, opfylder ikke behovet. Halmen snittes groft, og klumper af halm indeholdende sammenfiltrede strå, vil fra tid til anden passere maskinens snitteorganer. Strøgods af denne art har i praksis vist sig at give anledning til tilstopning af transportkassens udfødningsmekanisme og spredeaggregat.However, the automatic irrigation system requires power material of an appropriate degree of fineness to operate smoothly. In particular, straw that is not cut and thus comminuted sufficiently will easily give rise to stops in the feeding mechanism and other operational disturbances. The straw tearing and cutting machines available on the market today do not meet the need. The straw is roughly cut, and chunks of straw containing tangled straw will from time to time pass the cutting means of the machine. In practice, bedding of this kind has been found to cause clogging of the feeding box's feeding mechanism and spreading unit.
Det tekniske problem der skal løsesThe technical problem to be solved
Til grund for opfindelsen ligger den opgave, at anvise en maskine med forbedrede egenskaber med hensyn til oprivning og snitning af halm. Maskinens primære opgave er at sikre et ensartet og tilpas findelt strømateriale, således at de ovenfor omtalte driftsforstyrrelser i det automatiske strøningsanlæg undgås.The object of the invention is to provide a machine with improved properties for tearing and cutting of straw. The primary task of the machine is to ensure a uniform and adaptable finely divided flow material, so that the above mentioned disruptions in the automatic irrigation system are avoided.
Den nye teknikThe new technique
Det nye ved frembringelsen består i, at den med knive bestykkede, roterende tromle er lejret i en ramme, der er formet som et aflangt trug. I siderne af dette trug er der monteret faste knive, der virker som modskær for tromlens bevægede knive, hvilket bevirker en effektiv oprivning og snitning af halmen under tromlens rotation. Dette i kombination med, at dele af siderne og bunden i truget udgøres af hulplader med huller, der i størrelse er tilpasset den ønskede snitningsgrad, sikrer, at kun materiale, der er tilpas findelt, kan 2 DK 2008 00187 U3 passere maskinen. Klumper af halm og sammenfiltrede halmstrå vil forblive i truget, hvor materialet bearbejdes af tromlens knive og modskærene, indtil halmen er findelt i en sådan grad, at materialet i form af strøgods kan passere hullerne i hulplademe (soldene). Det frembragte strøgods afleveres i det automatiske strøningsanlægs transportkasse, hvorefter den programmerede strøningsproces kan gennemføres uden driftsmæssige forstyrrelser forårsaget af halmen.What is new about the production is that the knives, rotating drum, are mounted in a frame shaped like an elongated trough. At the sides of this trough are fixed knives which act as a counter cutter for the drum's moving blades, which results in an efficient tearing and cutting of the straw during the rotation of the drum. This, in combination with the fact that parts of the sides and bottom of the trough are made up of hollow plates with holes that are adapted in size to the desired degree of cutting, ensures that only material which is suitably divided can pass through the machine. Lumps of straw and tangled straw will remain in the trough, where the material is processed by the drum knives and the countercuts until the straw is comminuted to such an extent that the material can pass through the holes in the hollow plates (solids). The produced bedding is delivered to the automatic irrigation system transport box, after which the programmed irrigation process can be carried out without any operational disturbance caused by the straw.
Formålstjenligt er hulplademe indsat i truget som udskiftelige pladesektioner. På denne måde vil det være muligt at ændre snitningsgraden ved simpel udskiftning af hulplademe til en ny hulstørrelse.Conveniently, the hole plates are inserted into the trough as interchangeable plate sections. In this way, it will be possible to change the cut rate by simply replacing the hole plates to a new hole size.
Ved jævnfør krav 4 at anbringe knivene i skrueform på tromlen, opnår man, at snitningen forløber jævnt mider tromlens rotation og uden pludselige ryk i drivmeklanismen (gearmotoren). Endvidere sikrer skrueformen, at halmstråene bearbejdes successivt fra ende til anden, således at snitteeffekten bliver optimal. Resultatet er et strømateriale bestående af regulært snittede stråpartikler af rimelig ensartet længde.In accordance with claim 4, to place the blades in screw form on the drum, it is obtained that the cutting proceeds smoothly during the rotation of the drum and without sudden jerking of the drive mechanism (gear motor). Furthermore, the helix ensures that the straws are processed successively from end to end, so that the cutting effect is optimal. The result is a stream material consisting of regularly cut straw particles of reasonably uniform length.

Udførelseseksempler I den på tegningen viste udførelsesform består maskinen i det væsentlige af en trugformet ramme 1, en i truget lejret knivtromle 2, en gearmotor 3, og i hver ende af rammen 1 en opspændingskonsol 4. Den trugformede ramme 1 er sammensat af et antal langsgående, parallelle profiler 5, der forbinder to gavlstykker 6 og 7.1 truget indgår endvidere to hulpladesektioner 8, og tre knivbomme 9. Hulpladesektioneme 8 udgør sammen en vinkelformet bund i truget. På ydersiden af hvert gavlstykke er monteret et flangeleje 10.Embodiments In the embodiment shown in the drawing, the machine consists essentially of a trough-shaped frame 1, a knife drum-mounted 2, a gear motor 3, and at each end of the frame 1 a clamping bracket 4. The trough-shaped frame 1 is composed of a number of longitudinal In addition, parallel profiles 5 connecting two end pieces 6 and 7.1 trough also include two hollow plate sections 8, and three knife booms 9. The hollow plate sections 8 together form an angular bottom in the trough. A flange bearing 10 is mounted on the outside of each end piece.
Knivtromlen 2 er sammensat af et rørstykke 11, som er forsynet med påsvejsede navplader 12 i enderne. Koncentrisk i rørstykket 11 er indsat en gennemgående aksel 13, der er lejret i flangelejeme 10. Den ene ende 13a af akslen 13 er forlænget, og er indsat i gearmotorens 3 hulakse!.The knife drum 2 is composed of a pipe piece 11 which is provided with welded hub plates 12 at the ends. Concentric in the pipe piece 11 is inserted a through shaft 13 which is mounted in the flange bearings 10. One end 13a of the shaft 13 is extended and inserted into the hollow axis of the gear motor 3.
På ydersiden af rørstykket 11 er påsvejset et antal radiære laskeplader 14 forsynet med skruehuller 14a. Hver laskeplade er beregnet til påspænding af et knivblad 15. Laskeplademe befinder sig i planer vinkelret på knivtromles rotationsakse 16, således at 3 DK 2008 00187 U3 de påspændte knivblade 15 hver for sig bevæger sig i eget plan under tromlens rotation. Samlet set former knivene en skruelinie på knivtromlen. Knivbladene 15, hvoraf et enkelt er vist i forstørrelse i fig. 4 og 5, er fremstillet af hærdet stålplade med to skarpslebne sidekanter 16 og 17, og to skruehuller 18. De to sidekanter danner en spids vinkel med hinanden, og mødes i en knivspids 19. Knivbladet er nærmest trekantformet.On the outside of the pipe piece 11, a plurality of radial slab plates 14 are provided with screw holes 14a. Each wafer plate is intended for clamping a knife blade 15. The wafer plates are in planes perpendicular to the axis of rotation of the blade drum 16, so that the clamped blade blades 15 each move in their own plane during the rotation of the drum. Overall, the blades form a helical line on the blade drum. The knife blades 15, a single of which is shown in magnification in FIG. 4 and 5 are made of hardened steel plate with two sharp-cut side edges 16 and 17, and two screw holes 18. The two side edges form a pointed angle with each other and meet at a pinch 19. The blade is almost triangular.
Som modskær for knivtromlens knivblade 15 er den trugformede ramme 1 forsynet med de allerede omtalte tre knivbomme 9. Disse er udtageligt indsat mellem rammens 1 langsgående profiler 5. Hver knivbom består af en U-profil 20, på ydersiden af hvilken der er påsvejst et antal lasker 21. Delingen mellem disse svarer til delingen mellem knivtromlens laskeplader 14. På hver laske 21 er monteret et knivblad 22, som i form og størrelse svarer til de allerede beskrevne. Modskærene er placeret, så de bevægelige knivblade 15 på knivtromlen passerer tæt forbi modskærene (knivbladene 22) under tromlens rotation, hvorunder den tilstræbte snittevirkning opstår.As a cutter for the knife blade 15 of the knife drum, the trough-shaped frame 1 is provided with the already mentioned three knife bar 9. These are removably inserted between the longitudinal profiles of the frame 1. Each knife bar consists of a U-profile 20, on the outside of which a number of welds grooves 21. The partition between these corresponds to the partition between the blade plates 14 of the knife drum. On each sleeve 21 is mounted a knife blade 22 which corresponds in shape and size to those already described. The countercuts are positioned so that the movable knife blades 15 on the knife drum pass close past the countercuts (knife blades 22) during the rotation of the drum, during which the desired cutting action occurs.
Hulpladesektioneme 8 er vist i fig. 9 og 10. Hver hulpladesektion består afen med firkanthuller 23 udlokket plade 24, hvis to ender 25 og 26 er bukket i 90-graders vinkel. Pladen indspændes som bund i den trugformede ramme 1 mellem dennes langsgående profiler 5 og gavlstykker 6 og 7, se fig. 1 og 3. Det af knivbladene 15 og modskærene 22 fintsnittede materiale passerer ud gennem firkanthulleme 23 efterhånden som snitteprocessen forløber. Hullerne 23 er anbragt i et relativt tæt mønster, naturligvis under hensyntagen til, at pladen 24 bevarer tilstrækkelig styrke til at modstå de påvirkninger, som tromlen og den under bearbejdning værende halm giver anledning til.The hollow plate sections 8 are shown in FIG. 9 and 10. Each hollow plate section consists of square holes 23 protruding plate 24, whose two ends 25 and 26 are bent at a 90 degree angle. The plate is clamped as a bottom in the trough-shaped frame 1 between its longitudinal profiles 5 and end pieces 6 and 7, see fig. 1 and 3. The finely cut material of the knife blades 15 and the counter cut 22 passes out through the square holes 23 as the cutting process proceeds. The holes 23 are arranged in a relatively dense pattern, of course, taking into account that the plate 24 retains sufficient strength to withstand the stresses caused by the drum and the straw under machining.
Opfindelsen er ikke begrænset til den på tegningen viste og ovenfor beskrevne udførelsesform. Andre detailudformninger og andre konstruktive løsninger for maskinens enkelte bestanddele er tænkelig indenfor rammerne af denne opfindelse, ligesom anvendelsen af maskinen kan tænkes udvidet til andre områder end det anførte.The invention is not limited to the embodiment shown and described in the drawing. Other retail designs and other constructive solutions for the individual components of the machine are conceivable within the scope of this invention, and the use of the machine may be extended to areas other than those specified.
