Изобретение относитс к сельскохоз йственному машиностроению и может быть использовано в откидывающих и укладывающих устройствах дл уборочных машин, в частности в мотовилах.FIELD OF THE INVENTION The invention relates to agricultural machinery and can be used in tilting and stacking devices for harvesting machines, in particular in reels.

Известна граблина мотовила, содержаща трубчатый вал с отверсти ми, в которых расположены крючковые части пальцев , имеющих витковые части, внутри которых расположен фиксирующий элемент, св занный с трубчатым валом кронштейнами 1.A tine reel is known, comprising a tubular shaft with openings in which hooked parts of fingers are located, having coiled parts inside which there is a fixing element associated with the tubular shaft by brackets 1.

Недостатками указанной конструкции вл ютс неплотна фиксаци одинарных пальцев относительно трубчатого вала и их вибраци в процессе работы мотовила, что отрицательно .вли ет на качество уборки культур с легкоосыпающимис семенами, а также вызывает необходимость в увеличенной свободной производственной площади на участке сборки с каждой стороны граблины дл размещени фиксирующих элементов перед установкой их на место в граблине.The disadvantages of this design are the loose fixing of single fingers relative to the tubular shaft and their vibration during the operation of the reel, which negatively affects the quality of harvesting of crops with light-flowing seeds, and also necessitates an increased free production area on the assembly site on each side of the treadmill placing the locking elements before installing them in place in the tine.

Цель изобретени - повышение надежности креплени пальцев.The purpose of the invention is to increase the reliability of fastening fingers.

Указанна цель достигаетс тем, что на трубчатом валу кронштейны закреплены жестко и каждый из них имеет гнездо, причем трубчатый фиксирующий элемент закреплен в гнездах кронштейнов, а крючкова часть пальцев расположенна в отверсти х трубчатого вала с наклоном.This goal is achieved by the fact that the brackets are rigidly fixed on the tubular shaft and each of them has a socket, the tubular locking element is fixed in the slots of the brackets, and the hook part of the fingers is located in the slots of the tubular shaft.

На фиг. 1 изображена граблина мотовила с установленным фиксирующим элементом; на фиг. 2 - трубчатый вал, со свободно установленными одинарными пальцами; на фиг. 3 - то же, с жестко соед.шенными с ним кронщтейнамиFIG. 1 shows a tine reel with an installed locking element; in fig. 2 - tubular shaft, with single fingers freely mounted; in fig. 3 - the same with hard-wired brackets

1Q Граблина мотовила содержит трубчатый вал 1 со сквозными отверсти ми 2, в которые введены крючковые части 3 одинарных пальцев 4. В проем 5 витковой части одинарных пальцев введен фиксирующий элемент 6, прижатый в направлении 7 посредством болтовых крепежных элементов 8 к гнездам 9, выполненным в жестко соединенных с трубчатым валом кронштейнах 10.1Q The rake of the reel contains a tubular shaft 1 with through holes 2, into which hooked parts 3 of single fingers 4 are inserted. In the opening 5 of the winding parts of single fingers, a locking element 6 is inserted, pressed in direction 7 by means of bolted fasteners 8 to slots 9, made in brackets 10 rigidly connected to the tubular shaft.

Claims

The holes for the hook portion of the single fingers 4 are arranged so that the hook portion is located with an inclination (angle) in which the locking elements 6, after inserting them into the opening of the winding portion of the single fingers, hang near the nests of the brackets, but do not touch them. Single fingers 4 can be pressed to these sockets with the application of force and secured by means of bolted fasteners 8. When screwed together, 1 Ryukov part of the fingers elastically bends resting on the walls of the holes in the tubular shaft 1, and this frame firmly fixes single fingers suspended on it 4. Dense suspension of the fingers in the tine improves its operational properties and prevents fingers from oscillating during the operation of the reel, which negatively affects the quality of harvesting and causes an increase in grain losses, as well as a tine reliability, as single fingers perceive load predominantly in their plane of coil parts. In addition, simplification of the tine assembly is achieved, since it creates the opportunity to significantly reduce the cross section of the locking elements and freely insert them into the opening of the turn part of the fingers. At the same time, the placement of the coil part of the fingers relative to the brackets is such that it allows the fixing elements to be inserted together from the middle to the ends of the tine, and not vice versa, as in the known tine. In this case, there is no need for free areas on both sides of the tine; the assembly site can be close in width to the length of the tine itself, which saves production space. Reducing the cross section of the locking elements in comparison with the known ones allows reducing the metal consumption of the tine. Claims of the rake of the reel, comprising a tubular shaft with openings in which hooked parts of fingers are located, having coiled parts, inside which a fixing element connected to the tubular shaft by brackets is located, characterized in that The tubular shaft is rigidly fixed and each of them has a socket, the tubular locking element is fixed in the nests of the brackets, and the hook part of the fingers is located in the holes of the tubular shaft with an inclination.
