Abstract

Inventia se refera la un dispozitiv pentru cuplarea cultivatoarelor purtate pe tractoare, în primul rând a celor ce lucreaza în culturi cu talie înalta. Solutia tehnica prevede doua piese de cuplare fixate prin bride pe bara suport a cultivatorului si articulate cu triunghiul de cuplare prin niste bolturi concentrice, în sine cunoscute, dupa brate fixate, de asemenea, pe bara suport a cultivatorului prin bride si articulate pe corpul unui cilindru hidraulic prin niste cepuri ale acestuia, o tija a cilindrului hidraulic fiind articulata printr-un bolt la partea superioara a triunghiului de cuplare, comanda cilindrului hidraulic realizându-se prin intermediul a doua supape de sens deblocabile care permit modificarea pozitiei tijei cilindrului hidraulic la comanda data de tractorist. Cresterea luminii la sol a cultivatorului în pozitia de transport, posibilitatea de reglare a orizontabilitatii cultivatorului din mers si evitarea vatamarii plantelor sunt avantaje ale acestei solutii tehnice.The invention relates to a device for coupling cultivators worn on tractors, primarily those working in high-caliber crops. The technical solution provides for two coupling pieces fixed by the brace on the cultivator support bar and articulated with the coupling triangle by means of some concentric bolts, known per se, also after the arms, also fixed on the support bar of the cultivator by means of the clamps and articulated on the body of a cylinder a hydraulic cylinder rod being articulated by a bolt at the top of the coupling triangle, controlling the hydraulic cylinder by means of two releasable sense valves which allow the position of the hydraulic cylinder rod rod to be changed at the command date the tractorist. Increasing the ground light of the grower in the transport position, the possibility of adjusting the cultivator's horizontalism while walking and avoiding plant damage are advantages of this technical solution.
