Изобретение относитс к области сельскохоз йственного машиностроени , а именно к конструкции мотовила уборочных машин,The invention relates to the field of agricultural engineering, namely to the design of the reel of harvesting machines,

Известно универсальное эксцентриковое мотовило, содержащее граблины, шарнирно закрепленные в дерев нных лучах. К концам граблин приварены кривошипы, на пальцы которых надеты лучи эксцентрикового механизма 1.A universal eccentric reel is known, containing grabs, hinged in wooden beams. Cranks are welded to the ends of the tines, the fingers of which are fitted with the rays of the eccentric mechanism 1.

Недостатком известного мотовила вл етс то, что граблины при вращении недостаточно огибают контур, образованный шнеком и режущим аппаратом машины, в результате чего происход т значительные потери срезанной массы, накопление ее перед шнеком и неравномерна подача ее к шнеку.A disadvantage of the known reel is that the tines rotate insufficiently around the contour formed by the auger and cutting machine of the machine, as a result of which significant losses of the cut mass occur, its accumulation in front of the auger and uneven feed to the auger.

Цель изобретени - уменьшение потерь зерна путем приближени траектории движени граблин к контуру, образованному режущим аппаратом и нижней частью шнека машины.The purpose of the invention is to reduce grain losses by bringing the tines of movement of the tines to the contour formed by the cutting unit and the lower part of the machine screw.

Это достигаетс тем, что в мотовиле, содержащем жестко закрепленные на валу радиальные лучи с шарнирно закрепленными на них граблинами и эксцентриковый механизм с лучами, шарнирно соединенными с граблинами, соединительный узел междуThis is achieved by the fact that in the reel containing radial beams rigidly fixed on the shaft with grabs, hinged to them, and an eccentric mechanism with beams, hinged to grabs, the connecting node between

граблинами и лучами эксцентрикового механизма выполнен в виде кривошипно-шатунного механизма, шатун которого установлен шарнирно на граблине, а кривошип закреплен с возможностью регулировки его положени на луче эксцентриковбго механизма .The tines and beams of the eccentric mechanism are made in the form of a crank mechanism, the connecting rod of which is mounted hingedly on the tine bar, and the crank is fixed with the possibility of adjusting its position on the beam of the eccentric mechanism.

Мотовило содержит вал 1 с жестко прикрепленными к нему лучами 2, в которых шарнирно креп тс граблины 3, соединенные при помощи кривошипно-шатунного механизма с лучами 4 эксцентрикового механизма 5.The reel comprises a shaft 1 with beams 2 rigidly attached to it, in which the tine arms 3 are hinged, connected by means of a crank mechanism to the beams 4 of the eccentric mechanism 5.

Claims

The crank mechanism consists of a crank 6, pivotally connected to rake 3, crank 7. Crank 7 has a square neck, on which a sector 8 is rigidly mounted to adjust the position of the crank 7 on the beam 4 of the eccentric mechanism 5. For rigidity, a connecting link is inserted into the structure 9. For the operation of the reel at various grain sizes, the tilt angle of the tines 3 is adjusted using an eccentric mechanism 5. To select the movement of the tines 3 along the optimal trajectory in the zone where they should bend around the contour of the cutting unit This screw and screw make the second adjustment of the position of each tine 3 on the beam 4 of the eccentric mechanism 5 with the aid of sector 8. To do this, the tine 3 is mounted on the line passing through the shaft 1 and the eccentric mechanism 5 in the direction of the cutting unit. When sector 8 is rotated, the position of crankshaft 7 changes with respect to the rod 6, which is fixed. When the reel operates, the beams 2 and beams 4 rotate around axes that are eccentrically located and, therefore, translate relative to each other. These movements, using crankshaft 7 and connecting rod 6, are converted into rotational motion, with the angle of inclination of the rod 6, and hence the tine 3, changing. In the lower part of the trajectory of movement, tine 3 captures the cut mass and feeds it to the screw. Due to this design of the coupling assembly, the loss of oblique mass from the cutting apparatus is reduced, its accumulation in the area in front of the auger is eliminated, which creates conditions for uniform operation of the entire machine. An invention of a reel containing radial rays rigidly mounted on a shaft with hinged rias on them and an eccentric mechanism with rays hinged to tines, characterized in that, in order to reduce grain losses by bringing the trajectory of the moving body, the grablin towards the contour formed by the cutting the apparatus and the lower part of the machine screw, the connecting unit between the tines and the rays of the eccentric mechanism is made in the form of a crank-connecting rod mechanism, the connecting rod of which is hinged on pancake and rivoship adjustably secured in its position on the line of the eccentric mechanism.
