    This invention relates to the field of
    agricultural machine-building) and can be used in the design of combine harvesters.
    The purpose of the invention is to increase the efficiency of the separating device under severe cleaning conditions.
    Fig „1 shows the scheme of a self-propelled combine harvester, side viewJ in Fig" 2 - separating device, side view; in fig. 3 shows the supporting bars with a part of the adjusting device for changing their height position in FIG. 4 is a view A of FIG. 3.
    The combine contains a threshing drum I with a sub drum 2 located under it. A separating device is installed behind the drum 1 with separation drums 3 arranged parallel to the direction of mass movement, below each of which the separating element 4 is installed. Elements 4 are rigidly connected to two parallel to each other side longitudinal carrier bars 5, which are equipped with an adjusting device for changing their position in height and mounted on the sidewalls 6 of the combine. Elongated holes 7 are made in these sidewalls in order to allow the height of the bars 5 to vary in height. In the holes 7 there are bolts 8 welded to the bars m 5. Ball bearings 9 mounted between these two profiles parallel to each other 10 are installed on these bolts: enabling fixation of the arms 5 at a certain height to the outwardly protruding ends of the bolts 8 screw nuts I1, with the help of which the arms 5 can be pressed against the sidewalls 6 and thereby fixed.
    The adjusting device has lifting levers 12, pins 13, located in elongated holes 14 formed by longitudinal directions 15, which are mounted on bars 5, mounting rails 6 connected to pins 1 3 and pomosh; the help of the hinge element 18 - with one of the ends of the rod 19, as well as a lever system with levers 20 and 21 connected to each other by a common axis 22, and a single mechanism having a nut 23 screwed onto the threaded spindle 24, 15

    the second has a crank handle 25. The combine is also equipped with a pointer indicator of the position of the bars 5 in height, which has a scale of 26 and a boom 27,
    One ends of the lifting arms 12 are pivotally mounted on the sidewalls 6 by means of bearings 28, and the other ends are welded to the trunnion 13. The rim guides 15 are attached to the undersides of the bars 5, the length of the trunnions 13 are chosen such that levers 12 side, protrude from the guides 15. These protruding ends of the pins 13 are fitted with mounting rails 16, one for each of the pivots of the left and right-bearing-bars 5. The second end of the rod 19 is pivotally connected to the levers 20. The levers 20 are seated on General axis 22, to which is also welded e lever 21, the free end of the lever 21 is pivotally connected to the nut 23, the arrow 27 is attached to the lever 21, 22 as it is connected to the nut 23 through this lever.
    Each separation element 4 is made in the form of a transverse trough-shaped steel perforated sheet, which is connected to the supporting bars 5 by means of lateral stops 29 attached to the end lateral ends of the sheet.
    During the operation of the combine harvester, the need arises to change the working gap between the separating elements 4 and the separating drums 3. The said working gap is changed, for example, in order to obtain a sparing separation mode for residual grain depending on the specific climatic conditions in which the harvesting is carried out. harvest and the type of crop harvested. In order to change the working clearance, the position of the bars 5 carrying the separation elements 4 must be changed in height. Movement of the bars 5 may be required to move along the height of the separator to the parts of the separator when fire is removed.
    or blockage of these parts, oh
    The height adjustment of the bars 55 5 is carried out by rotating the handle 25. In this case, the levers 20 and 21 rotate on the axis 22 and move in the longitudinal direction the rod 19 and
    thirty

    the rails 16, as a result of which the lifting arms 12 rotate in the bearings 28 and raise or lower the support bars 5 with separation elements 4. The distance between the elements D and the drums 3 is determined with the help of a dial gauge on a scale of 26 ..,
    Thus, raising or lowering the timbers 5 is carried out with a geometric closure in the mates of parts of the adjusting device, which increases the efficiency of the proposed design under severe harvesting conditions (when processing an overmoistened crop).
