Description
Den foreliggende oppfinnelse vedrører en overlastsikring The present invention relates to an overload protection
for ploger, spesielt fulldreieploger av den art som er angitt i den innledende del av krav 1. for ploughs, especially full-turn plows of the type specified in the introductory part of claim 1.
Ved en kjent utførelsesform av denne art (DE-PS 21 21 555) In a known embodiment of this kind (DE-PS 21 21 555)
er kuleleddskålen for kuleleddet mellom trykksylinderen og sentreringsplaten utført som en uttagning i innersiden av sentreringsplaten. Den kuleformede ende av stempelstangen hos trykksylinderen står i inngrep med denne kuleleddskål• Dersom plogstangen ved overlast utfører en oppoverrettet svingebevegelse, så er denne begrenset til en maksimal vinkel på ca. 30° fordi kuleleddforbindelsen mellom sentreringsplaten og trykksylinderen utelukker en større svingevinkel for sentreringsflaten. Ved tidligere angitte løftehøyder for ploglegemets skjærspiss nødvendig-gjør denne begrensning av svingevinkelen en dimensjon av plogstang-lengden som er forholdsvis stor og i uønsket grad øker avstanden mellom tyngdepunktet for plogen og dennes koblingsplan. Denne tyngdepunktsavstand til koblingsplanet påvirker det kippmoment som er virksomt om aksen for bakhjulet av slepeinnretningen, og som utøves fra plogen på nevnte innretning. is the ball joint cup for the ball joint between the pressure cylinder and the centering plate made as a recess in the inner side of the centering plate. The ball-shaped end of the piston rod of the pressure cylinder engages with this ball-and-socket cup• If the plow rod performs an upward swinging movement when overloaded, this is limited to a maximum angle of approx. 30° because the ball joint connection between the centering plate and the pressure cylinder precludes a greater angle of rotation for the centering surface. At previously specified lifting heights for the cutting tip of the plow body, this limitation of the turning angle makes a dimension of the plow bar length that is relatively large and increases the distance between the center of gravity of the plow and its connection plane to an undesirable degree. This center of gravity distance to the coupling plane affects the tilting moment which is effective about the axis of the rear wheel of the towing device, and which is exerted from the plow on said device.
Til grunn for den foreliggende oppfinnelse ligger den oppgave å skaffe en sikring av den innledningsvis angitte art ved hvis hjelp avstanden fra plogtyngdepunktet til plogens koblingsplan kan reduseres betydelig. The present invention is based on the task of providing a fuse of the type indicated at the outset, by means of which the distance from the plow's center of gravity to the plow's connection plane can be significantly reduced.
Oppgaven løses ved en sikring som ifølge oppfinnelsen er karakterisert ved de trekk som er angitt i den karakteriserende del av krav 1. Vedrørende ytterligere utførelsesformer henvises der til kravene 2 og 3. The task is solved by a fuse which, according to the invention, is characterized by the features specified in the characterizing part of claim 1. Regarding further embodiments, reference is made there to claims 2 and 3.
Sikringen ifølge oppfinnelsen muliggjør med meget enkle midler oppoverrettede svingebevegelser for sentreringsplaten og dermed plogstangen, som dekker en vesentlig større vinkel, f.eks. 45°, slik at ved samme angitte verdi for løftehøyden for ploglegemets skjærspiss ved overlasttilfeller kan byggelengden av plogstangen reduseres vesentlig og man får således en plog hvis tyngdepunktavstand til koblingsplanet er betydelig forkortet. The fuse according to the invention enables, with very simple means, upward swinging movements for the centering plate and thus the ploughbar, which covers a significantly larger angle, e.g. 45°, so that with the same specified value for the lifting height of the cutting tip of the plow body in cases of overload, the construction length of the plow bar can be significantly reduced and you thus get a plow whose center of gravity distance to the coupling plane is significantly shortened.
Et utførelseseksempel på oppfinnelsesgjenstanden vil bli omtalt i'det følgende under henvisning til tegningen. Fig. 1 er et riss av en plog med en overlastsikring ifølge oppfinnelsen mellom plogrammen og plogstangen. Fig. 2 viser et vertikalsnitt gjennom en utførelsesform for An embodiment of the object of the invention will be discussed in the following with reference to the drawing. Fig. 1 is a view of a plow with an overload protection according to the invention between the plow frame and the plow bar. Fig. 2 shows a vertical section through an embodiment of
en overlastsikring. an overload protection.
Fig. 3 er et snitt etter linjen III-III på fig. 2. Fig. 3 is a section along the line III-III in fig. 2.
Fig. 4 er et snitt i likhet med fig. 2, som anskueliggjør sikringsdelene i overlastendestilling. Fig. 4 is a section similar to fig. 2, which shows the securing parts in overload position.
Den plog som er vist på fig. 1 er utført som en fullvende-plog og oppviser en plogramme 1 som om en plogakse bæres dreibart av en kobling 2 for tilknytning av plogen til trepunkts-hydraulikken i en ikke vist landbruksslepeinnretning. På plogrammen 1 er der via overlastsikringer 3 forbundet plogstenger 4 The plow shown in fig. 1 is designed as a full-turn plow and exhibits a plow frame 1 as if a plow axle is rotatably supported by a coupling 2 for connecting the plow to the three-point hydraulics in an agricultural towing device, not shown. Plow bars 4 are connected to the plow frame 1 via overload protection devices 3
til hvilke er festet ploglegemer 5. Som det nærmere fremgår av fig. 2-4, består hver av overlastsikringene 3 av et med plogrammen 1 stivt forbundet flerkantet hus 6, en til plogstangen 4 stivt forbundet flerkantet sentreringsflate 7 som kan føres forskyvbart i huset, men er sikret mot dreining, og som i driftstilling av ploglegemet ligger an mot husanslag 8, 9, samt en trykksylinder 10 som via kuleledd 13, 14 ligger an mot såvel den med en innvendig kuleleddskål 11 forsynte sentreringsplate 7 som mot den overfor denne beliggende husbakvegg 12. Kuleleddskålen 11 på sentreringsplaten 7 er festet på en bærer 15 som er svingbart forbundet med sentreringsplaten 7 om en hovedsakelig horisontalt forløpende tverrakse 16. Dessuten oppviser bæreren 15 aksetapper 17, 18 som er lagret i lagerblokker 19, 20 som kan skrus løsbart inn i sentreringsplaten 7. to which plow bodies 5 are attached. As can be seen in more detail from fig. 2-4, each of the overload protectors 3 consists of a polygonal housing 6 rigidly connected to the plow frame 1, a polygonal centering surface 7 rigidly connected to the plow bar 4 which can be slidably guided in the housing, but is secured against turning, and which in the operating position of the plow body rests against housing stops 8, 9, as well as a pressure cylinder 10 which via ball joints 13, 14 rests against both the centering plate 7 provided with an internal ball joint cup 11 and against the housing rear wall 12 located opposite this. The ball joint cup 11 on the centering plate 7 is attached to a carrier 15 which is pivotally connected to the centering plate 7 about a mainly horizontally extending transverse axis 16. In addition, the carrier 15 has axle pins 17, 18 which are stored in bearing blocks 19, 20 which can be releasably screwed into the centering plate 7.
Ved sin øvre og nedre tverrkant (ved fullvendeploger, ved bedploger bare ved underkanten) oppviser sentreringsplaten 7 en sylindrisk støttedel 21, 22 som har en diameter større enn tykkelsen av sentreringsplaten. Videre oppviser sentreringsplaten et midlere forbindelsesområde 7' for den utenfra tilkoblede plogstang 4, hvilket område oppviser en utover og bakover mot plogstangenden forskutt stilling pga. knekninger. Det gjør at den disponible plass i huset 6 øker, og at den svingevinkel som sentreringsplaten kan utføre ved overlast, blir større. Dette forhold fremgår av fig. 4 som viser delene av sikringen i over-las tendes til lingen . At its upper and lower transverse edge (in the case of full-turn ploughs, in the case of bed ploughs only at the lower edge) the centering plate 7 has a cylindrical support part 21, 22 which has a diameter greater than the thickness of the centering plate. Furthermore, the centering plate has a middle connection area 7' for the externally connected plow bar 4, which area shows a position shifted outwards and backwards towards the plow bar end due to kinks. This means that the available space in the housing 6 increases, and that the turning angle that the centering plate can perform in the event of an overload becomes greater. This relationship appears from fig. 4 which shows the parts of the fuse in the over-load tends to the ling.
