Description

Nosilni okvir s poljedelskim žetvenim strojem, zlasti rotacijskim kosilnikomSupport frame with agricultural harvester, especially rotary mower

Izum se nanaša na nosilni okvir z žetvenim strojem, zlasti rotacijskim kosilnikom, s sprego za prigradnjo na tritočkovni dvigalni mehanizem vlačilca, z značilnostmi, podanimi v uvodnem delu 1. patentnega zahtevka.The invention relates to a carrier frame with a harvesting machine, in particular a rotary mower, with a coupling for mounting on a three-point tug lift mechanism, with the characteristics given in the introductory part of claim 1.

Tovrstni nosilni okviri se večinoma uporabljajo za kosilnike, ki naj bi karseda brez vztrajnosti sledili neravninam tal, da ne bi puščali nepokošena mesta in da ne bi povzročali motnje zaradi poškodb ali odnašanja travnate ruše ali zaradi vdiranja kosilnika v tla. Pri tem je pomembno, da okviri stroja ne izvajajo zgolj dvižno in spuščalno gibanje, temveč lahko pri tem zavzamejo v prečni smeri tudi znatne poševne položaje.Such mounting frames are mainly used for mowers, which should, as far as possible, invariably follow the uneven ground, so as not to leave undamaged places, and not to disturb the lawn or damage to the lawn or the mower entering the ground. It is important that the frames of the machine not only carry out lifting and lowering movements, but can also take considerable sloping positions in the transverse direction.

Iz DE-OS 33 22 030 je znan nosilni okvir za čelni kosilnik s kosilnim bobnom za prigradnjo na tritočkovni dvigalni mehanizem vlačilca, pri katerem je okvir kosilnika okoli vodoravne osi središčno nihalno obešen na nosilnem okviru in opremljen z obojestransko glede nanj razporejenimi elementi, sestoječimi iz vzmeti, za omejevanje nihalne širine.DE-OS 33 22 030 discloses a carrier frame for a front mower with a mower drum for attachment to a three-point tug lift mechanism, in which the mower frame is pivotally pivotally mounted on the support frame about the horizontal axis and is provided with elements arranged on both sides of it. springs for limiting the swing width.

Prestavljanje po višini samo sledi vzporedno, v vodoravnem položaju krožnika kosilnika, preko plavajočega položaja tritočkovnega dvigalnega mehanizma.Height-shifting only follows in parallel, in the horizontal position of the mower plate, via the floating position of the three-point lift mechanism.

Ta razporeditev ne obsega nikakršne možnosti prestavljanja za usmeritev okvira kosilnika v njegov položaj k tlom.This arrangement does not include any repositioning option for directing the mower frame to its position toward the ground.

Iz DE-GM 67 50 238 je razviden vlačilcu prigrajen čelni nosilni okvir za rotacijski kosilnik s kosilnim bobnom, pri katerem lahko okvir kosilnika prav tako niha okoli sredično razporejene vodoravne osi, in pri katerem je dodatno predviden vmesni okvir v obliki prečnega nosilca, ki je po sebi prestavljiv okoli vodoravne osi in zgibno pritrjen na dveh čelnih nakladalnih dvigalkah ter hkrati preko dveh prestavnih vreten, ki sta zgibno pritrjeni med vmesnim okvirom in čelnima nakladalnima dvigalkama, s katerima se da nastaviti navpični položaj, v katerem krožnik kosilnika vodoravno nalega na tla.DE-GM 67 50 238 discloses to the tractor a front support frame for a rotary mower with a mower drum, in which the mower frame can also oscillate about a centrally arranged horizontal axis, and in which an intermediate frame in the form of a transverse support is provided, which is inherently adjustable about the horizontal axis and pivotally mounted on two front-end hoists and simultaneously via two shifting spindles pivotally secured between the intermediate frame and front-end hoists to adjust the vertical position in which the mower plate horizontally rests on the ground.

Pomanjkljivost te razporeditve je odsotnost tritočkovnega dvigalnega mehanizma, ki zagotavlja vzporedno gibanje po višini okvira kosilnika, kot tudi naravnanost prestavnih vreten, ki pri stranskih zasučnih gibanjih za prilagoditev tlom postavita kosilnik v neugoden položaj glede na tla, s čimer lahko pride do motenj ali škode, kajti krožnik kosilnika lahko potem v določenih legah reže v tla ali mestoma odnaša travnato rušo.The disadvantage of this arrangement is the absence of a three-point lift mechanism that provides parallel movement along the height of the mower frame, as well as the alignment of the shifting spindles, which, in the lateral rotational movements for adjusting the soil, place the mower in a disadvantageous position with respect to the ground, which may cause interference or damage, because the mower plate can then cut into the ground or in some places take away the grass.

Dodatni vmesni okvir podraži razporeditev in oteži prigradjo le-te.The additional intermediate frame makes the arrangement more expensive and makes it difficult to attach it.

Naloga izuma je ustvariti čelni nosilni okvir za kmetijski žetveni stroj za prigraditev na tritočkovni dvigalni mehanizem vlačilca, ki je primeren za uporabo rotacijskega kosilnika, zlasti s kosilnim bobnom, pri čemer je obešenje okvira stroja kosilnika zasnovano tako, da le-ta izvaja gibanje po višini, poševne lege prečno glede na smer vožnje pa lahko zavzame, ne da bi s tem dal povod za motnje ali celo poškodbe stroja ali travnate ruše.It is an object of the invention to provide a front carrier frame for an agricultural harvesting machine for attachment to a three-point tug lift mechanism suitable for use with a rotary mower, in particular with a mower drum, the suspension of the mower machine frame being designed to move in height , the sloping sides, depending on the direction of travel, can be occupied without causing disturbance or even damage to the machine or grass.

To nalogo se pri stroju z značilnostmi, podanimi v uvodnem delu 1. patentnega zahtevka, reši z značilnostmi, podanimi v značilnostnem delu.In the case of a machine with the characteristics given in the introductory part of claim 1, it is solved by the features given in the characteristic part.

Podzahtevki se nanašajo zlasti na prednostne izvedbe izuma in so, prav tako kot zahtevek 1, sočasno del opisa prijave.The sub-claims relate in particular to the preferred embodiments of the invention and, like claim 1, are simultaneously part of the description of the application.

Z uporabo stranskih drogov, kot tudi Središčnega obešenja s kroglatim zgibom, se, kot posledica prilagoditve tlom, omogoči nadaljnje območje stranskega izravnalnega gibanja. Podpiranje stranskih drogov z dolžinsko spremenljivim hranilnikom energije, zlasti pa Središčno podpiranje na nosilni konzoli v območju središčnega kroglastega zgiba, na katerem je obešen žetveni stroj, učinkovito duši najprej stranske zavihtitve okvira kosilnika in pri tem pojavljajoča se nihanja, ne da bi se s tem morali odpovedati omembe vredni razbremenitvi žetvenega stroja, in to zato, ker gred in z njo povezam prisloni delujejo kot stransko stabiliziranje žetvenega stroja.The use of lateral poles as well as the center pivot with the ball joint allows for a further area of lateral compensatory movement as a result of the adaptation to the ground. Supporting lateral poles with a long variable energy storage, and in particular Central support on a support bracket in the area of the center ball joint on which the harvester is suspended, effectively dampens laterally the lateral rotations of the mower frame without the need for oscillations. to deny mention of the unburdening of the harvesting machine, because the shaft and its attachment act as a lateral stabilization of the harvesting machine.

Razporeditev prislonov omogoča zlasti enostavno izdelovanje dušeno vzmeteno stabilizacijo žetvenega stroja, tudi za močne prečne nagibe, ob uskladitvi pojavljajočih se momentov.The arrangement of the backrests makes it especially easy to produce a damped spring stabilization of the harvesting machine, even for strong transverse inclinations, while adjusting the appearing torques.

V izogib poškodbam ali hrupu je zelo prednostna uporaba gumijastih blažilcev. S tlačno vzmetjo kot dolžinsko spremenljivim hranilnikom energije med zasučno roko gredi in konzolo v vzdolžni smeri nosilnega okvira je podan zadosten prostor za vgradnjo, pri čemer je pomembna nastavljivost prednapetja vzmeti za uporabo pri žetvenih strojih različnih mas. Prav tako prednostno izvedbo izuma tvori uporaba hidravličnega močnostnega valja s priključenim tlačnim zbiralnikom.Rubber dampers are highly preferred to avoid damage or noise. The pressure spring, as a long-varying energy storage device between the rotating arm of the shaft and the cantilever in the longitudinal direction of the supporting frame, provides sufficient space for mounting, with an important adjustability of the spring preload for use in harvesting machines of different masses. Also preferred embodiment of the invention is the use of a hydraulic power cylinder with a pressure manifold connected.

Zgibna pritrditev nosilnega okvira preko nosilne roke z nosilno konzolo na okvir kosilnika preko kroglastega zgiba omogoča s središčno zgibno pritrditvijo uravnoteženo nihalno gibanje okvira stroja, pri čemer uporaba središčne ležajne konzole neposredno na okviru kosilnika dovoljuje izbiro primerne, ugodne geometrije drogov za dvig okvira stroja, katera določa potek izravnalnega gibanja na neravninah tal.The articulated attachment of the support frame via the support arm with the support bracket to the mower frame via a ball joint allows the machine to be pivotally balanced by pivotally mounting, while the use of a center bearing bracket directly on the mower allows the selection of a suitable, favorable rod geometry for raising the machine frame, which determines the course of the compensatory movement on the uneven ground.

Zlasti enostavno in stabilno prigradnjo se doseže, če je ležajna konzola za središčni zgib sočasno zasnovana kot držalo za vstopno gonilo, ki je na prednosten način nameščeno nad okvirom kosilnika, in ki skupaj z vmesnim gonilom tvori nad okvirom kosilnika pogonsko linijo za kosilnik.Particularly simple and stable mounting is achieved if the center pivot bearing bracket is simultaneously designed as an input gearbox holder, preferably positioned above the mower frame, and which together with the intermediate gearbox, form a drive line for the mower unit above the mower frame.

Pri tem je zlasti prednostno, če je zgibna pritrditev središčnega kroglastega zgiba glavnega droga razporejena zelo nizko na okviru stroja, kajti s tem se pri nihajočem zavihtitvenem gibanju spredaj dvigne predelovalno orodje, če je zgibna pritrditev prestavnih členov ustrezno izbrana.It is particularly advantageous if the articulation attachment of the central ball joint of the main mast is arranged very low on the machine frame, because in the case of oscillating swivel movement, the processing tool is raised in front, if the articulation attachment of the gear members is properly selected.

Zlasti enostavno zasnovo se dobi z uporabo dvignjenih ročic, ki omogočajo primemo naravnavo prestavnih členov, ki prednostno sestoje iz navojnih vreten.In particular, a simple design is obtained by using raised arms that allow the gear members, which preferably consist of threaded spindles, to be adjusted.

Razporeditev s strani kosilnika razporejenih zgibov prestavnih vreten med dvignjenimi ročicami na središčnemu zgibu nasproti ležečo stran okvira kosilnika podaja skupaj z nizko ležečim središčnim zgibom ugodno lego kosilnika pri izravnalnih gibanjih na neravninah tal, ki dopuščajo stransko dviganje ali spuščanje okvira kosilnika.The arrangement of the spindle spindle joints arranged by the mower between the raised arms on the center joint opposite the mower frame side, together with the low center pivot, provides a favorable position for the mower in counterbalancing movements on uneven ground that allow lateral lifting or lowering of the frame.

Pri enostavnem dviganju okvira kosilnika se s prisloni in njih dušenjem prepreči prenihana gibanja, tako da tudi pri cestnem transportu ne pride do zibanja.By simply lifting the lawnmower frame, the stops and their damping prevent the movement from being stopped, so that there is no rocking during road transport.

Pri dviganju po višini okvira kosilnika sodeluje tritočkovno obešenje vlačilca, sklopljeno s svojo hidravliko v lebdečem položaju, pri čemer se da spodnji drog letega razbremeniti z vzmetmi, da se zmanjša pritisk na podlago krožnika kosilnika, kar še izboljša prilagoditev tlom.When lifting the height of the mower frame, it involves a three-point suspension of the tractor coupled with its hydraulics in the hovering position, which can be relieved by the lower pole of the fly in order to reduce the pressure on the base of the mower plate, which further improves the adaptation to the ground.

Prijava je v nadaljevanju opisana s pomočjo risb izvedbenega primera, kjer kaže sl. 1 razporeditev stroja po izumu v pogledu od zgoraj, sl. 2 prerez po črti I-I s sl. 1The application is described below with reference to the drawings of an embodiment, where FIG. 1 is an elevational view of the machine according to the invention; 2 is a cross-section along line I-I of FIG. 1

Nosilni okvir 1 sestoji iz prigradnega nosilca 21 s priključki za oba spodnja drogova 22, 22’ tritočkovnega hidravličnega priključka vlačilca, pri čemer nosilec 21 na nasproti ležeči strani opremljen z nosilno roko 3, ki je v vozni smeri 20 razporejena nad obdelovalnim strojem, rotacijskim kosilnikom, in na katere koncu je navzdol obrnjena nosilna konzola 19, ki nosi središčni zgib 4, kateri je zasnovan kot krogelni zgib, ki je uležajen med dvema stranskima stenama na okviru 2 kosilnika pritrjene ležajne konzole 23, katera je podaljšana in sočasno namenjena kot držalo za vstopno gonilo 24, tako da središčni zgib s tem neposredno leži na okviru 2 kosilnika na strani, ki je obrnjena v smeri vožnje 20.The carrier frame 1 consists of a mounting bracket 21 with attachments for the two lower bars 22, 22 'of the three-point hydraulic attachment of the tractor, with the mounting bracket 21 on the opposite side having a support arm 3 arranged in a driving direction 20 above the machine, a rotary mower. , and at the end facing downwards is a support bracket 19, which carries a center joint 4, which is designed as a ball joint, which is mounted between two side walls on the frame 2 of the mower of the fixed bearing bracket 23, which is extended and simultaneously intended as a holder for the gearbox 24, so that the center joint thus directly rests on the frame of the 2 mower on the side facing in the direction of travel 20.

Na nasproti ležeči strani okvira 2 kosilnika, kije obrnjena k nosilnemu okviru 1, sta v stranskih območjih 12, 12’ okvira kosilnika dvignjeni ročici 10, 10’ in 11, 11’, ki sta zasnovani paroma in med katerima sta uležajena s strani okvira kosilnika razporejena, kot krogelni zgib 6, 6’ zasnovana zgiba stranskih drogov 7, 7’.On the opposite side of the frame 2 of the mower facing the support frame 1, in the lateral regions 12, 12 'of the mower frame, the arms 10, 10' and 11, 11 'are raised, which are designed in pairs and are supported by the frame of the mower. arranged as a ball joint 6, 6 &apos; designed a lateral rod joint 7, 7 &apos;.

S strani nosilne roke razporejena, prav tako kot krogelni zgib zasnovana zgiba 5, 5’ stranskih drogov 7, 7’ sta zgibno pritrjena na čepa 25, 25’ neprekinjene, v dveh prečnih nosilcih 26, 26’ uležajene gredi 29, ki po sebi poteka prečno glede na smer vožnje 20.Spaced apart from the supporting arm, as well as a ball joint designed 5, 5 'of the lateral poles 7, 7' are pivotally attached to the studs 25, 25 'continuous, in two transverse supports 26, 26' of the recessed shaft 29, which runs by itself transverse to the direction of travel 20.

Prečna nosilca 26, 26’ sta pritrjena na nosilnem okviru 1 in središčno medsebojno razmaknjena.The transverse beams 26, 26 'are fixed to the support frame 1 and spaced centrally from each other.

V območju med prečnima nosilcema 26, 26’ je na gredi 29 nameščena vrtilno toga zasučna roka 33. Med slednjo kot opornim ležajem 35 in drugi oporni ležaj 35, 35’ je vstavljen dolžinsko spremenljiv hranilnih energije 34 v obliki tlačne vzmeti, pri čemer je vzmetno vreteno 37, za vodenje podprto med ležajnima nosilcema 17, 17’, na zasučni roki 33 uležajeno z ležajnim somikom 40, v prednjem območju 36 nosilne konzole 19 nosilnega okvira 1 pa z ležajnim očesom 15 in somikom 16.In the area between the transverse beams 26, 26 ', a rotating rigidly rotating arm 33 is mounted on the shaft 29. Between the latter, as a support bearing 35 and a second bearing 35, 35', a longitudinally variable feed energy 34 is inserted in the form of a pressure spring, with a spring the spindle 37, supported between the bearings 17, 17 'for guidance, supported on the swivel arm 33 by the bearing snap 40, and in the front area 36 of the carrier bracket 19 of the bearing frame 1 by the bearing eye 15 and the snail 16.

Vzmetno vreteno 37 nosi vzmetna krožnika 18, 18’, med katerima je napeto držana tlačna vzmet in katerih razmik se da nastavljati s pomočjo vretenske matice 38, s čimer se da nastavil osnovni položaj 8 gredi 29 in prednapetje vzmeti.The spring spindle 37 bears spring plates 18, 18 ', of which a pressure spring is held between which the spacing can be adjusted by means of the spindle nut 38, thereby adjusting the basic position 8 of the shaft 29 and the prestressing of the spring.

Na gredi 29 sta vrtilno togo obojestransko nameščeni prislonski roki 14, 14’, na katerih konceh sta predvidena prislona 13,13’, ki sta opremljena z dušilnima elementoma 32,32’ za stranska drogova 7,7’ in razporejena pod slednjima.On the shaft 29, the pivot arms 14, 14 'are provided on the pivot rigidly, the ends 13.13' being provided at the ends, which are provided with damping elements 32.32 'for the side bars 7.7' and arranged below the latter.

V osnovnem položaju 8 gredi 29, kadar kosilni krožnik 28 kosilnika še ravno vodoravno nalega na tla, nalegata stranska drogova 7,7’ na prislona 16,16’ in pri tem zavzemata glede na vodoravnico navzgor potekajoč, odpirajoč se kot 9, pri čemer sta s strani kosilnika razporejena zgiba 6,6’ glede na vodoravnico razporejena višje kot s strani nosilne roke raporejena zgiba 5,5’ (sl. 2).In the basic position 8 of the shaft 29, when the mower plate 28 of the mower is horizontal, it rests horizontally on the ground, the lateral poles 7.7 'rest against the supports 16.16', and with respect to the horizontal, they are running upwards, opening as 9, with the hinge is positioned 6,6 'from the mower relative to the horizontal, and 5,5' higher than the side of the supporting arm (Fig. 2).

S tem se doseže, da se pri stranskih nihalnih gibanjih okvira 2 kosilnika tako kosilne bobne 27 kot tudi kosilni krožnik 28 pri dvigu v vozni smeri 20 spredaj nastavi navzgor in se izogne vdiranju v tla, s čimer se pri neravninah tal v veliki meri doseže prilagoditev le-tem.This enables the lateral swinging movements of the mower frame 2 of the mower drum 27 as well as the mower plate 28 to be adjusted upward in the upward movement 20 in order to avoid intrusion into the ground, thereby substantially adjusting to them.

Pri izboklinah ali poglobitvah tal se kosilnik v celoti dvigne ali spusti, medtem ko se na nosilni okvir 1 deluje preko spodnjih drogov 22, 22’ in zgornjega droga 30 s pomočjo tritočkovne hidravlike, ki je v delovnem položaju vklopljena v lebdeči položaj, pri čemer je za zmanjšanje naležnega tlaka, zaradi izboljšanja prilagoditve kosilnika tlom, predvidena vzmetna razbremenitev 31, ki je ponazoijeno na sl. 2 predvidena v območju tritočkovne hidravlike.In the case of bumps or deepening of the floor, the mower is fully raised or lowered while acting on the supporting frame 1 via the lower bars 22, 22 'and the upper bar 30 by means of a three-point hydraulic system, which is in the working position engaged in a hovering position, in order to reduce the contact pressure, in order to improve the adaptation of the mower to the soil, a spring relief 31 is provided, which is illustrated in FIG. 2 provided in the three-point hydraulic range.

Če se zaradi neravnine tal stransko območje 12 ali 12’ okvira 2 kosilnika spusti navzdol, se nasproti ležeče stransko območje 12 ali 12’ sočasno dvigne ali spusti, pri čemer navzdol potujoči stranski drog 7 ali 7’ sojemlje prirejeno prislonsko roko 14 ali 14’, s čimer se preko zasučne roke 33 tlačno vzmet, tj. dolžinsko spremenljiv hranilnik 34 energije stisne in po drugi strani shrani to energijo, ki jo po premaganju talne ovire ponovno odda na zasučno roko 33 in gred 29, ki s tem preko drugega stranskega droga 7’ ali 7 ujame navzdolnje gibanje drugega stranskega območja 12’ ali 12 okvira 2 kosilnika, s čimer izredno hitro in učinkovito duši nihajna gibanja.If the lateral side area 12 or 12 'of the mower frame 2 is lowered due to uneven ground, the lateral side area 12 or 12' is raised or lowered at the same time, with the lateral side arm 7 or 7 'downstream of the adapted stop arm 14 or 14', thus, 33 a rotating spring through the rotating arm, i. the longitudinally variable energy reservoir 34 compresses and, on the other hand, stores this energy, which, after overcoming the floor obstacle, again transmits it to the rotating arm 33 and the shaft 29, which thereby traverses downward movement of the second lateral region 12 'via the second lateral pole 7' or 7; 12 frame 2 mower to dampen oscillatory movements quickly and efficiently.

Med vozno po cesti izvaja kosilnik le zelo majhna, močno dušena zibalna gibanja, kajti stranska drogova 7, 7’ nalegata na prislonska okvira 14, 14’, medtem ko drog tritočkovne hidravlike drži kosilnik v dvignjenem položaju.Only very small, heavily damped rocking movements are engaged in the road hauler as the lateral poles 7, 7 'rest against the support frames 14, 14' while the three-point hydraulic pole holds the mower in the raised position.
