Изобретение относитс  к дноуглубительной техлнкэ, преимущественно к морским и речным земснар дам, снабженным черпаковы- ми цеп ми, ИзЕестчы устройства проушин черпаков и промежуто-1НЫ7 звеньев, снабженные С-образ ными втулками с распорными клинь ми охватывающие поверхность пальцев fl, 2 J, Недостатком известных устройств  вл етс  их высока  изнашиваемость. Известаа проушина черепковой цепи земснар да , :о,слючаюша  корпус, выполненный с проемом, в котором Закреплена С-образна  вставка i .i; J. Недостатком этого технического решени   вл етс  то, что С-образна  вставка имеет одинаковую толшину по всему сечению, хот  она изнашиг.аетс  только на участке, ограниченном дугой, вследствие чего быстро выходит из стро . Целью изобретени   вл етс  увеличение срока эксплуатации черпаковой цели путем перераспределени  изнашиваюшихс  поверхностей проушин. Указанна  цель достигаетс  тем, что С-образна  вставка выполнена переменного сечени  серповидной формы. На фиг. 1 изображен узел соединени  че1 паковой цепи земснар да; на фиг. 2 - то же, сечение по А-А на фиг, 1; на фиг. 3 - проушина цепи с проемом. Проушина черпакоБой цепи включает корьпус 1, имеющий проем, в котором закреплена С-юбразна  вставка 2, выполненна  переменного сечени  серповидной формы. В проеме корпуса посредством пальца 3 закреплен корпус черпака 4. Длина дуги проема ограничена углом оС , причем концы дуги заканчиваютс  уступами 5. Кажда  С-образна  вставка вьшолнена с переменным сечением Ъ толщины стенки,причем больша  толщина расположена со стороны нагруженного участка. С-образную вставку изготавливают из износостойкого материала и запрессовывают в проем корпуса. Формула изобретени  Проушина черпаковой цепи земснар да, включающа  корпус, выполненный с проемом, вThe invention relates to dredging technology, mainly to sea and river dredgers, equipped with scoop chains, and devices for lugs of scoops and spacing-1N7 links, equipped with C-sleeves with spacer wedges covering the surface of fl, 2 J, Disadvantage The known devices are their high wear. The known eye of the shredded chain of the dredge, o, slyuchayucha body, made with an opening in which the C-shaped insert is fixed i .i; J. The disadvantage of this technical solution is that the C-shaped insert has the same thickness over the entire cross section, although it wears out only in the area bounded by the arc, as a result of which it quickly goes out of order. The aim of the invention is to increase the service life of the scoop target by redistributing the wearing surfaces of the lugs. This goal is achieved by the fact that the C-shaped insert is made of a variable crescent shaped cross section. FIG. 1 shows a junction assembly through a packer chain of a dredger; in fig. 2 - the same, section along A-A in FIG. 1; in fig. 3 - chain eye with an opening. The eyelet of the scoop chain includes a core 1, which has an opening in which the C-junction box 2 is fixed, is made of a crescent-shaped variable cross-section. The body of the scoop 4 is fixed in the opening of the housing by means of the finger 3. The arc length of the opening is limited to an angle C, the ends of the arc ending with steps 5. Each C-shaped insert is filled with a variable cross section of wall thickness, with the greater thickness located on the side of the loaded section. C-shaped insert is made of wear-resistant material and pressed into the opening of the housing. Formula of the Invention The bucket chain of the dredger, including the body, made with the opening, in
