摘要：
The invention relates to an equipment meant for making equally spaced planting holes of reduced dimensions, in worked land, with a view to planting forestry saplings and agricultural crop seedlings obtained either in nutritive beds or solariums, with a view to transplanting them in open field for intensive cropping. According to the invention, the equipment consists of three subassemblies, i.e. a first subassembly for transport and positioning in the field, a second subassembly having a shaft (8) fixed in a semi-housing (10) provided with a recess in which there is a roller bearing (9) with two rows of balls, stiffened to the semi-housing (10) by means of a clamping cap (11) inside of which there is mounted a cross shaft (8) with a collar, provided at one end with a thread on which a nut (13) is clamped for replacing and fixing a movable profiled cam (12), the generatrix of which is copied by a rotary tappet (14) transmitting the motion to a longitudinal rod (15) threaded at one end, compressed by means of a cylindrical helical spring (16) and of a tensioning adjusting system (17) while, at the other end of the rod (15) there is placed a vertical sliding planter (18), where protection is ensured by means of a front cap (19), and a third subassembly consisting of a fastening plate framework (20) to which a caisson (21) is undetachably fixed, while inside it, on a vertical branch, there is a roller (23) transmitting the rotation to the cross shaft (8) with a collar which is common to the two subassemblies, roller (23) which is tensioned by the mechanism consisting of a helical cylindrical spring (24), and on the horizontal branch there are two back-band idlers (22) meant for stretching a toothed profiled elastomeric belt track (25), where protection is provided by means of a cap (27) .Invenţia se referă la un echipament destinat realizării gropilor de plantare, de dimensiuni reduse, dispuse echidistant, în teren prelucrat, în vederea plantării puieţilor forestieri şi
