handling equipment. SUBSTANCE: agricultural manipulator has flat base 1 with outside supports 2 and eyelets equipped with fingers for connection to tractor hydraulic suspender tie-rods, supporting and rotating column 3 with cantilevered boom and load-lifting mechanism. Each eyelet is made E-shaped, with hollow fingers of smaller and larger diameters inserted in eyelet openings for mutual engagement, mounting, fixation and dismantling. Each finger has member for fixing it in predetermined position with respect to another finger. Mentioned member is made in the form of pair of diametrically oriented pins mounted in the interior of finger of larger diameter, and U-shaped bayonet slots on outer entry part of finger of smaller diameter. Manipulator is further equipped with device for mounting, fixing and dismantling of mutually joined hollow fingers. This device has a number of parts including thrust bushing, spherical layer and spherical support with tap wrench, with all mentioned parts being mounted on threaded pin. Internal surface of finger of larger diameter is provided with threaded portion for receiving thrust bushing and for inserting finger of smaller diameter from threaded part side. Internal surface of finger of smaller diameter is equipped with threaded part for receiving the pin. EFFECT: increased efficiency by reduced readjustment time and wider operational capabilities. 10 dwg
