SELF-PROPELLED MODULE FOR PENETROMETERS ACTUATORS

The invention relates to a self-propelled module for penetrometers actuators, meant for agricultural works, for the evaluation of the soil compaction state caused by the repeated passage of agricultural machines and agrotechnical works which were carried-out. According to the invention, the module comprises a drive train assembly () of internal combustion engine and gear box type, a running system assembly () consisting of a chassis () supported by some rollers () on two caterpillar chains () driven by some driving wheels (), a hydrostatic assembly () consisting of a power generating set (), an electric motor () and a hydrostatic pump () and a mechanism assembly with a system for clamping in three points () of an actuator for penetrometers () making one body by fixing with some assembling elements of nut-screw type, the mechanism assembly with a clamping system in three points () comprising an upper or central tie-bar consisting of a double drive hydrostatic cylinder (), two lower or side tie-bars () which are connected, by a drive shaft () mounted with some sliding bearings () on a frame () fixed on a chassis () and another double drive hydrostatic cylinder () which, upon performing the maximal stroke k, may be locked by means of a bolt () and a securing device () with a hinged lever (). Invenţia se referă la un modul autopropulsat, pentru dispozitive de acţionare a penetrometrelor, destinat lucrărilor din agricultură, la evaluarea stării de compactare a solurilor, cauzată de trecerile repetate ale maşinilor agricole şi de lucrările agrotehnice efectuate. Modulul conform invenţiei este alcătuit dintr-un ansamblu motopropulsor () de tip motor, cu ardere internă şi cutie de viteze, un ansamblu sistem de rulare (), format dintr-un şasiu () sprijinit cu nişte role () de două şenile () antrenate de nişte roţi () motrice, un ansamblu hidrostatic (), compus dintr-un grup electric (), un motor electric () şi o pompă hidrostatică (), şi un ansamblu mecanism cu sistem de prindere în trei puncte (), al unui dispozitiv de acţionare a penetrometrelor (), şi care formează un corp comun prin fixarea cu nişte elemente de asamblare de tipul şurub-piuliţă, ansamblu mecanism cu sistem de prindere în trei puncte (), fiind compus dintr-un tirant superior sau central, format dintr-un cilindru hidrostatic cu dublă tracţiune (), doi tiranţi inferiori sau laterali (), care sunt legaţi, prin intermediul unor tije de ridicare () reglabile, cu nişte manşoane (), de un arbore de acţi
