Abstract

En lekegravemaskin har en stasjonær ramme (1-4) med sete (2) og en graveskuffe (5,5') som er leddforbundet og bæres av dels en gravebom (6), dels et leddstag (7). Gravebom (6) og leddstag (7) har hver sin manøvreringspak (10 henholdsvis 11). Hver spak (10, 11) er svingbar om en nedre akse, idet deres nedre ende er dreibart opplagret i et rammefast lagerorgan (12), slik at spakene (10, 11) for forflytting av gravebom (6) og/eller leddstag (7) kan svinges i forhold til hverandre eller i fellesskap. Ifølge den foreliggende oppfinnelse har man - under opprettelse av god bevegelighet i lekegravemaskinen - utelukket klemfare blandt annet mellom de enkelte spaker (10, 11) og den stasjonære gravemaskinramme (1-4), mellom graveskuffen (5,5') og den stasjonære ramme (1-4) og mellom graveskuffens (5,5') gravetannparti (51) og leddstaget. For dette formål er nevnte rammefaste lagerorgan (12) for svingbar opplagring av de to spaker(10, 11) utformet med en bueformet spalte (13) hvori griper forskyvbart inn tapplignende inngrepsorgan (19-21) på de to spakenes (10, 11) nedre endepartier (14, 15), hvike tapplignende inngrepsorganers (19-21) forskyvningsstrekning i den bueformet spalte (13) i det rammefaste lagerorgan (12) begrenses av spaltens (13) lengdeutstrekning, hvilket indirekte begrenser de enkelte manøvreringsspakenes (10, 11) svingevinkel i vertikalplanet, for eksempel i forhold til den stasjonære rammes (1-4) opprettstående del (1), slik at det i enhver arbeidsstilling for lekegravemaskinen blir opprettholdt tilstrekkelig avstand mellom en bevegelig del og en annen bevegelig del eller en fast del av rammen (1-4) til at klemfare er utelukket.A play excavator has a stationary frame (1-4) with a seat (2) and a digging bucket (5.5 ') which is jointed and supported by a digging boom (6) and a joints (7). Digging boom (6) and articulated linkage (7) each have their own maneuvering pack (10 and 11, respectively). Each lever (10, 11) is pivotable about a lower axis, its lower end being pivotally supported in a frame-fixed bearing member (12), so that the levers (10, 11) for moving the boom (6) and / or the joints (7) ) can be pivoted relative to each other or jointly. In accordance with the present invention - while establishing good movement in the play excavator - clamping hazards have been excluded, inter alia, between the individual levers (10, 11) and the stationary excavator frame (1-4), between the excavator drawer (5.5 ') and the stationary frame. (1-4) and between the excavator portion (5.5 ') of the excavator portion (51) and the joint. For this purpose, said frame-fixed bearing means (12) for pivotally supporting the two levers (10, 11) are formed with an arcuate slot (13) in which slidably engages pin-like engaging means (19-21) on the two levers (10, 11). the lower end portions (14, 15), the displacement distance of the pin-like engagement members (19-21) in the arcuate slot (13) of the frame-bearing bearing (12) is limited by the length of the slot (13), which indirectly limits the individual maneuvering levers (10, 11) turning angle in the vertical plane, for example with respect to the upright portion (1) of the stationary frame (1-4), so that in any working position of the play excavator sufficient distance between one movable part and another movable part or a fixed part of the frame is maintained (1-4) to prevent clamping hazards.
