Ved en fra DE-U-7318934 kendt høbjærgningsmaskine har det som rammekonstruktion udformede chassis ikke tilstrækkelig stabilitet, da rammekonstruktionen er udformet som plan trekant eller trapez, i hvis underste hjørnepunkter tværud-10 liggerne, der bærer riverotorerne, er lejret svingbart.In a hay-lifting machine known from DE-U-7318934, the chassis designed as a frame construction does not have sufficient stability, since the frame structure is designed as a flat triangle or trapezoid, in the lower corner points of which the transverse projections carrying the river rotors are mounted pivotally.

Ved en fra AT-B-296673 kendt høbjærgningsmaskine tjener en stiv trækarm som chassis, til hvilket en stiv tværbærebjæl-ke, der bærer de to riverotorer, er ledforbundet med lodret 15 svingakse. På bærebjælken er der anbragt en hjælperamme til hjælpemidlerne, der styrer det høstede materiale.In a hay-lifting machine known from AT-B-296673, a rigid towing arm serves as a chassis, to which a rigid transverse beam carrying the two river rotors is articulated with vertical pivot axis. A supporting frame is provided on the support beam for the aids controlling the harvested material.

Ved en fra DE-U-6942397 kendt høbjærgningsmaskine er chassiset udformet T-formet. Beskyttelsesindretninger for rive-20 rotorerne er lejret svingbart omkring de i kørselsretning liggende akser på tværbærebjælken, der bærer riverotorerne.The chassis is T-shaped by a chipping machine known from DE-U-6942397. Protective devices for the turret rotors are pivotally mounted around the axes of travel on the cross support beam supporting the turret rotors.

Til grund for opfindelsen ligger den opgave at frembringe en høbjærgningsmaskine af den i indledningen omtalte slags, 25 som udmærker sig ved et stabilt ulykkessikret chassis, der ved kun mindre ændringer kan anvendes til såvel en trukket som en skubbet maskine.The object of the invention is to provide a hay-lifting machine of the kind mentioned in the introduction, which is distinguished by a stable accident-proof chassis that can only be used for both a towed and a pushed machine with only minor changes.

Opfindelsen løser den stillede opgave ved hjælp af de i den 30 kendetegnende del af krav 1 angivne foranstaltninger.The invention solves the stated task by means of the measures specified in the characterizing part of claim 1.

Yderligere fordelagtige konstruktionsmæssige kendetegn fremgår af underkravene 2 og 3.Further advantageous structural features are set forth in subclaims 2 and 3.

35 Opfindelsen forklares i det efterfølgende ved hjælp af tegningen, på hvilken: 2The invention is explained in the following by means of the drawing, in which: 2

Ulv ID//Z/ D IWolf ID // Z / D I

Fig. 1 viser en trukket høbjærgningsmaskine set fra oven, 5 fig. 2 viser en skubbet høbjærgningsmaskine set fra oven.FIG. 1 is a plan view of a towed hoisting machine; FIG. 2 is a top view of a pushed hay-lifting machine.

Ved den i fig. 1 set fra oven skematisk viste høbjærgningsmaskine 1 drejer det sig om en rotorrive med to rive-10 rotorer 2 og 3, som er sluttet til et chassis 4. Chassiset 4 kan ved hjælp af en trækstang 5 hænges efter en ikke vist traktor.In the embodiment shown in FIG. 1 is a schematic view of the hoisting machine 1 shown schematically, it is a rotor rake with two turret rotors 2 and 3 connected to a chassis 4. The chassis 4 can be hung by means of a drawbar 5 after a tractor not shown.

Chassiset 4 har form som et dobbelt-T, det vil sige, det 15 har en længdedrager 6, som viser i kørselsretningen, til hvilken en forreste tværdrager 7 og en bageste tværdrager 8 er tilsluttet.The chassis 4 is in the form of a double T, that is, it has a longitudinal carrier 6, which shows in the direction of travel to which a front cross carrier 7 and a rear cross carrier 8 are connected.

Den forreste henholdsvis bageste tværdrager 7, 8 kan være 20 udformet i et stykke og være skruet sammen med drageren eller bestå af to dele, som fastskrues på længdedrageren 6.The front and rear transverse supports 7, 8, respectively, may be integrally formed and screwed together with the carrier or consist of two parts which are screwed onto the longitudinal carrier 6.

Længden af tværdragerne 7 og 8 svarer omtrent til akselafstanden mellem riverotorerne 2 og 3.The length of the transverse beams 7 and 8 corresponds approximately to the axle distance between the river rotors 2 and 3.

Omtrent midt på længdedrageren 6 findes der på begge sider nedad visende udliggere 9. De frie ender på disse udliggere 9 optager i kørselsretningen visende svingakser 10, omkring hvilke rivehjulene 2 og 3 ved hjælp af hydraulikcylindre 30 11, som ved stempelstangen er ledforbundet til bærearme 12 for rivehjulene 2 og 3, kan svinges 90° ind i en opad og indad visende transportstilling. Rivehjulenes 2 og 3 tænder afdækkes i denne transportstilling i det mindste delvis af advarselstavler 13, som er anbragt omtrent i hjørnepunkter-35 ne på det dobbelt-T-formede chassis, så at en kilde til mulige uheld er udelukket.Approximately in the middle of the longitudinal carrier 6 there are downwardly projecting projections 9 on both sides. The free ends of these projectors 9 take up in the direction of travel showing pivot axes 10, around which the tear wheels 2 and 3 are supported by hydraulic cylinders 30 11, which are connected to the supporting arms 12 by the piston rod. for the tear wheels 2 and 3, can be swiveled 90 ° into an upward and inward transporting position. The teeth of the tear wheels 2 and 3 are covered in this transport position at least in part by warning boards 13, which are located approximately at the corner points 35 of the double-T-shaped chassis, so that a source of possible accidents is excluded.

Ved den trukne høbjærgningsmaskine ifølge fig. 1 er chassiset 4 støttet på jorden ved hjælp af yderligere løberhjul 14, der er anbragt på den bageste tværdrager 8. Med denne 5 foranstaltning er der sikret en særskilt føring af chassiset - uafhængigt af de ligeledes ved riverotorerne 2 og 3 forhåndenværende løberhjul. ·In the towed hay-lifting machine according to FIG. 1, the chassis 4 is supported on the ground by means of additional impeller 14 mounted on the rear transverse carrier 8. This 5 measure ensures a separate guide of the chassis - independent of the impeller wheels also present at the river rotors 2 and 3. ·

Ved høbjærgningsmaskinen, som er vist skematisk i fig. 2, 10 drejer det sig om en konstruktion, der finder anvendelse ved den samme grundmaskine. Som følge heraf har de samme dele de samme henvisningsnumre.In the hay-lifting machine shown schematically in FIG. 2, 10, it is a construction which is applicable to the same basic machine. As a result, the same parts have the same reference numbers.

Chassiset 4 er i forhold til den foran forklarede kon-15 struktion ændret således, at høbjærgningsmaskinen skubbes af den ikke viste traktor. Til tilslutning af høbjærgningsmaskinen er den bageste tværdrager 8 forsynet med en tilslutningsramme 15. 1The chassis 4 has been changed in relation to the construction as explained above, so that the mowing machine is pushed by the tractor not shown. For attachment of the hitch lifting machine, the rear transverse carrier 8 is provided with a connection frame 15. 1

Den forreste tværdrager 7 bærer et midt for længdedrageren 6 anbragt efterløberhjul 16, med hvilket chassiset 4 yderligere støttes på jordoverfladen.The front transverse carrier 7 carries a center wheel for the longitudinal carrier 6 arranged with impeller 16, with which the chassis 4 is further supported on the ground surface.
