Abstract

Inventia se refera la un dispozitiv pentru reglarea mecanismelor de ridicare ale masinilor agricole, la care reglarea sa poate fi facuta atît în functie de pozitie, cît si în functie de forta. Valoarea fortei este etalonata în functie de semnalul de indicare a pozitiei la anumite momente, astfel încît o modificare a raportului de mixare în reglorul de mixare sa nu duca la o modificare a pozitiei. Etalonarea se face prin intermediul unui regulator PI si a unui circuit de memorie, într-un amplificator diferential, efectuîndu-se scaderea semnalului traductorului de indicare a fortei a unui semnal suplimentar înmagazinat, astfel încît, în starea etalonata, semnalul de indicare a fortei este egal cu cel de indicare a pozitiei. în aceasta situatie, o noua reglare a reglorului de mixare nu provoaca o modificare a pozitiei dispozitivului de ridicare. Datorita unuor dispozitive suplimentare, se obtine ca aceasta etalonare sa poata fi mereu reînnoita, în functie de una sau mai multe marimi. La o actiune a reglorului valorii prescrise a pozitiei, se slabeset semnalul de mixare, astfel încît este atinsa în scurt timp pozitia dorita.
