Opfindelsen angår en rem for sigtekædebånd til kartoffeloptager, med grupper af nittehuller, der er anbragt side om side i remmens tværretning og fordelt med indbyrdes samme afstand langs remmens endeløse længde, og som tjener til optagelse af nitter for kædestave, der ligger an mod og er forbundet fast med remmens overside, og hvor remmen i sin overside har en profilering til forsænket optagelse af kædestavenes ender.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a potato harvester sieve chain strap, having groups of rivet holes arranged side by side in the transverse direction of the belt and spaced apart along the endless length of the belt, serving to receive rivets for chain rods abutting and connected firmly to the upper side of the strap, and wherein the strap in its upper side has a profile for recessed uptake of the ends of the chain rods.
Remme af denne art består som regel af gummi forstærket med et vævindlæg. Ved en kendt remkonstruktion med glat remunderside består profileringen i removersiden af tværnoter, der strækker sig over rembredden og har en dybde, som er lig med tykkelsen af kædestavenes ender. I denne konstruktion ligger oversiden af enderne af 2 149703 de til remmen nittede kædestave i højde med removersiden, men nittehovederne rager op over removersiden, så de kan beskadige de kartofler, som transporteres på sigtekædebåndet. Udformningen med tværnoter bevirker desuden, at remmen får en svækkelse i forhold til remme med en overside, der også er udformet glat, og fra hvilken de pånit-tede kædestavender rager op i fuld tykkelse. Svækkelsen af remmen, som skyldes tværnoterne, reducerer den trækkraft, som remmen kan optage. Da tværnoterne befinder sig i området af remmens gummimateriale over forstærkningsindlægget og altså ligger over remmens bøjningsneutrale zone, vil det svækkede gummilag mellem notbunden og forstærkningsindlægget udsættes for forøgede påvirkninger under passagen omkring styrerullerne. I disse områder sker der nemlig under denne passage en udvidelse, som optræder to gange for hvert fuldt omløb af sigtekædebåndet. Remme af denne type har derfor tendens til efter kort tids forløb at beskadiges i området af kædestavendernes fastgørelsessted. Denne tendens forstærkes af den omstændighed, at sigtekædebånd, der har sådanne remme, drives af kædestavhjul, der indgriber med kædestavene, hvilket medfører, at kædestavene udsættes for betydelige trækkræfter i remmens løberetning. Denne påvirkning, der optræder pulserende under sigtekædebåndets omløb, hvor kædestavenderne overfører drivkraft til remmen, influerer under driften u-gunstigt på remmen, navnlig i området mellem bunden og den væg af tværnoterne, som forløber i transportretningen.Belts of this kind usually consist of rubber reinforced with a weave insert. In a known belt construction with a smooth strap bottom, the profile in the strap surface consists of transverse grooves extending across the belt width and having a depth equal to the thickness of the ends of the chainstays. In this construction, the upper side of the ends of the chain rivets riveted to the belt are at the same height as the belt surface, but the rivet heads project above the belt surface so that they can damage the potatoes transported on the sieve chain belt. In addition, the design with cross-grooves causes the belt to weaken with respect to belts having a top surface which is also smoothly shaped and from which the threaded chain rods protrude in full thickness. The weakening of the belt due to the cross notes reduces the traction that the belt can absorb. As the transverse grooves are in the region of the rubber material of the strap above the reinforcing insert and thus are above the flexural neutral zone of the strap, the weakened rubber layer between the groove bottom and the reinforcement insert is subjected to increased stresses during the passage around the guide rollers. In these areas, during this passage, an expansion occurs, which occurs twice for each full cycle of the sieve chain band. Consequently, belts of this type tend to be damaged in a short period of time in the area of the attachment point of the chain rods. This tendency is compounded by the fact that sieve chain belts having such belts are driven by chain rod wheels which engage with the chain rods, causing the chain rods to be subjected to considerable pulling forces in the belt direction. This effect, which occurs pulsating during the circulation of the sieve chain belt, where the chain rods transmit driving force to the belt, adversely influences the belt during operation, especially in the area between the bottom and the wall of the transverse grooves extending in the direction of transport.
Der kendes endvidere en remkonstruktion til sigtekædebånd for kartoffeloptagere, hvor remmen har en glat, usvækket overside og en underside udformet med tværknaster, dvs. at remmen har sin underside udformet som en art tandrem. Denne remkonstruktion anvendes til sigtekædebånd, som bibringes deres transportbevægelse via de til remmene overførte drivkræfter. Ved denne konstruktion ligger kædestavenderne imidlertid frit på removersiden, så de af sigtekædebåndet transporterede kartofler udsættes for svære beskadigelser.Also known is a belt construction for sieve chain belts for potato pickers, the belt having a smooth, unimpaired upper side and a lower side formed with crossbars, ie. that the strap has its underside shaped like a kind of toothed belt. This belt construction is used for sieve chain belts which are imparted to their transport movement via the driving forces transmitted to the belts. However, in this construction, the chain rods lie freely on the remover side, so that the potatoes transported by the sieve chain belt are subjected to severe damage.
Opfindelsen har til formål at udforme den indledningsvis omhandlede remkonstruktion på en sådan måde, at den får en lang levetid, selv når den udsættes for en stærk belastning, og at den udelukker beskadigelse af de transporterede kartofler i området af kædestavenderne og kan drives direkte med henblik på at bevirke sigte-kædebåndomløbet.The invention has for its object to design the strap structure initially provided in such a way that it has a long life, even when subjected to a heavy load, and excludes damage to the transported potatoes in the area of the chain rods and can be driven directly for the purpose of on effecting the sieve-chain belt circulation.
Til opnåelse heraf er remmen ifølge opfindelsen ejendommelig ved, at der i removersiden langs hver gruppe af nittehuller er udformet et par beskyttelseslæber, der strækker sig opad fra den øvre 3 T&9703 remhovedflade op over oversiden af kaedestavenes ender og nitternes hoveder, og at der i remundersiden er udformet tværknaster, der er anbragt i hvert sit område mellem op til hinanden grænsende beskyttelseslæbepar, og som strækker sig nedad fra den nedre remhovedflade.In order to achieve this, the belt according to the invention is characterized in that a pair of protective lips extending upwardly from the upper 3 T & 9703 belt head surface over the top of the ends of the chain rods and the heads of the rivet side are formed in the belt surface along each group of rivet holes. are formed transverse bumps which are disposed in each region between adjacent lip lip pairs extending downwardly from the lower belt head surface.
Med denne udformning opnår man en remkonstruktion, hvor man undgår enhver kontakt mellem kartoflerne og kædestavenderne samt de dertil hørende nittehoveder, så beskadigelse af kartoflerne virksomt udelukkes. Dertil kommer, at man med udformningen med beskyttelseslæber og tværknaster opnår et bånd, der i alle områder har et usvækket tværsnit til optagelse af trækbelastninger, og som er i besiddelse af en høj grad af fleksibilitet og ikke længere er udsat for at beskadiges i de trækkraftoptagende områder.With this design, a belt construction is obtained, whereby any contact between the potatoes and the chain rods as well as the associated rivet heads is avoided, so that damage to the potatoes is effectively excluded. In addition, with the design with protective lips and crossbones, a tape is obtained which in all areas has an unimpaired cross section for absorbing tensile loads, which has a high degree of flexibility and is no longer subject to damage in the traction absorbing areas.
Ifølge opfindelsen kan de mod hinanden vendende yderflader af beskyttelseslæberne, som indgår i op til hinanden grænsende beskyttelseslæbepar, danne et afrundet tværtrug sammen med den øvre remhovedflade, og tværknasterne kan have et trapezformet tværsnit med sideflanker, som indmunder i den nedre remhovedflade i området under beskyttelseslæbernes basisdel.According to the invention, the facing outer faces of the protective lips, which form into adjacent protective lip pairs, can form a rounded transverse truss with the upper belt head surface, and the crossbars may have a trapezoidal cross-section with side flanks which open into the lower belt head surface in the area of the protective lips. base.
Med disse udformninger opnår man en forsætning af beskyttelseslæbeparrene og tværknasterne i forhold til remmens løbe- og længderetning, som sikrer en særlig gunstig spændingsfordeling i remmen og eliminerer spændingskoncentrationer, som kan medføre et for tidligt slid.With these designs, the protective lip pairs and cross-lugs are set off relative to the belt's running and longitudinal direction, which ensures a particularly favorable tension distribution in the belt and eliminates stress concentrations that can cause premature wear.
Opfindelsen forklares nærmere i det følgende under henvisning til tegningen, hvor fig. 1 viser et afbrudt perspektivbillede af et sigtekæde-bånd til kartoffeloptagere, med en udførelsesform for remmen ifølge opfindelsen, fig. 2 skematisk et afbrudt længdesnit gennem remmen, og fig. 3 et afbrudt snit efter linien III-III i fig. 2.The invention will be explained in more detail below with reference to the drawing, in which fig. 1 is a broken perspective view of a potato harvester sieve chain band showing an embodiment of the belt according to the invention; FIG. 2 schematically shows a longitudinal section through the belt; and FIG. 3 is a sectional view taken along line III-III of FIG. 2nd
Fig. 1 viser et sigtekædebånd, der har to ydre remme 1 af en og samme udformning. Sigtekædebåndet kan imidlertid også have en midterrem, hvis der anvendes en større båndbredde. Sigtekædebåndet har desuden et antal kædestave 2, der er udformet med fladtrykte ender 3, og som i området af disse er forbundet fast med remmen l's overside ved hjælp af nittegrupper, som hver indeholder to eller tre forbindelsesnitter 4. Sigtekædebåndets forreste ende løber i området af remmene 1 omkring styreruller 5, medens dets bageste, 4 149703 ikke viste ende løber, omkring profilerede driv- og styreruller.FIG. 1 shows a sieve chain belt having two outer straps 1 of one and the same configuration. However, the sieve chain belt may also have a center belt if a larger bandwidth is used. The sieve chain belt further has a plurality of chain rods 2 formed with flat printed ends 3 and which in the region thereof are connected firmly to the upper side of the belt 1 by means of rivet groups, each containing two or three connecting rivets 4. The front end of the sieve chain belt runs in the region of the belts 1 around guide rollers 5, while its rear, not shown end runs, around profiled drive and guide rollers.
Som navnlig vist i fig. 2 har remmen 1 en hoveddel 6, der omfatter et område indesluttet mellem linier 7 og 8, som repræsenterer den øvre og nedre remhovedflade. Den endeløse rem 1, der består af gummi eller lignende materiale og et vævindlæg 9 anbragt i remhoveddelen 6's midterplan, har over sin fulde længde grupper af nittehuller 10, der er anbragt side om side i remmens tværretning og fordelt med indbyrdes samme afstand i remmens længderetning. Når remmene 1 er forbundet med kædestavene 2, strækker nitterne sig gennem nittehullerne 10. Kædestavene 2's ender 3, der ligger an mod den øvre remhovedflade 7 og er fastgjort til denne ved hjælp af nitterne 4, er med deres sider indfattet i hvert sit par beskyttelseslæber 11, 12. Hvert par beskyttelseslæber 11, 12, der hører til hver sin gruppe af nittehuller 10, danner en enhed sammen med remhoveddelen 6 og strækker sig så langt op over den øvre remhovedflade 7, at kædestavene 2's ender 3 og nitterne 4's hoveder er anbragt forsænket mellem de opadragende beskyttelseslæber 11, 12. De mod hinanden vendende yderflader 13 af beskyttelseslæberne 11, 12, som indgår i op til hinanden græn-sende beskyttelseslæbepar, danner sammen med den øvre remhovedflade .7 et afrundet tværtrug 14, fig. 2. Tilsvarende har beskyttelseslæberne 11, 12 en udvidet basisdel, som udadtil går under afrun-. ding over i remhoveddelen 6. Beskyttelseslæberne 11, 12, der indsnævrer sig i retning opad, har en tilstrækkelig eftergivelighed i deres øvre område, som strækker sig op over oversiden af kædestavenderne 3, så de ved kontakt med kartoflerne 15 ikke beskadiger disse. På remmens underside er der i området mellem op til hinanden grænsende beskyttelseslæbepar 11, 12 anbragt tværknaster 16, der strækker sig nedad fra den nedre remhovedflade 8, og som har et trapezformet tværsnit med sideflanker 17, som indmunder i den nedre remhovedflade 8 i området under beskyttelseslæbernes basisdel. Beskyttelseslæberne 11, 12 og tværknasterne 16 ender i hvert sit af to planer 18, 19, der er beliggende i omtrent samme afstand fra vævindlægget 9 i remhoveddelen 61 s midterplan.As shown in particular in FIG. 2, the belt 1 has a body portion 6 comprising an area enclosed between lines 7 and 8 which represents the upper and lower belt head surfaces. The endless belt 1, which consists of rubber or similar material and a weave insert 9 arranged in the median plane of the belt body 6, has over its full length groups of rivet holes 10 arranged side by side in the transverse direction of the belt and spaced apart at the same distance in the longitudinal direction of the belt. . When the straps 1 are connected to the chain rods 2, the rivets extend through the rivet holes 10. The ends 3 of the chain rods 2, which abut the upper belt head surface 7 and are secured thereto by the rivets 4, are covered with their sides in each pair of protective lips. 11, 12. Each pair of protective lips 11, 12, each belonging to a group of rivet holes 10, forms a unit together with the strap head portion 6 and extends so far up the upper strap head surface 7 that the ends 3 of the chain rods 2 and the heads of the rivets 4 are placed recessed between the upwardly protecting lips 11, 12. The facing outer faces 13 of the protective lips 11, 12, which form into adjacent protective lip pairs, together with the upper strap head surface .7 form a rounded transverse trough 14, fig. 2. Similarly, the protective lips 11, 12 have an expanded base portion which extends outwardly during the rounding. The protective lips 11, 12, which narrow in the upward direction, have a sufficient resilience in their upper region which extends upwardly over the top of the chain rods 3 so that they do not damage them upon contact with the potatoes 15. On the underside of the belt, in the region between adjacent protective lip pairs 11, 12, crossbars 16 extend downwardly from the lower belt head surface 8 and have a trapezoidal cross-section with side flanks 17 which open into the lower belt head surface 8 in the region below the base part of the protective lips. The protective lips 11, 12 and the transverse lugs 16 end in each of two planes 18, 19 located at approximately the same distance from the weave insert 9 in the median plane of the belt body portion 61.
