    The combine contains at its front end a heder with a header 2 and a conveyor attached to it, 3, behind which is a feed beater 4. The molten device 1 is housed in the housing 5 of the combine and contains a threshing drum 6 in the form of a rotor surrounded by a casing 7, with part of the casing 7 is formed by a lattice concave 8. The threshing device 1 has working bodies which, in the area of the concave B, are made in the form of threshing strips 9 located along helical lines m.
    On the casing 7 there are mounted stationary screw-shaped guides 10 located in the upper part of the casing 7. The drive of the drum 6 has a motor 11.
    t
    Under the casing 7 there is a oscillating stepped bottom 12 having longitudinal strips 13 dividing the bottom 12, for example, into four sections
    and designed to prevent excessive grain dropping towards the roll of the combine. Below bottom 12, a cleaning fan 14 is installed, also having a sieve 15, a collecting chamber 16, at the end of which the connection 3
    The conveyor 17 is not fed to supply the cleaned grain to the hopper 18.
    The threshing device 1 is bounded laterally by the left 19 and right 20 side walls of the body 3, and from the bottom by a stepped bottom 12, the threshing drum 6 being symmetrically located in the casing 7, so that the axis 21 of rotation of the threshing drum 6 extends in the middle vertical plane 22. Barbara 8 overlaps the inscribed angle ti (FIG. 2), equal to approximately 140, which is divided into two equal angles by the vertical plane 22. The upper half of the threshing drum 6 is covered by a solid cylindrical casing 7.
    The combine is provided with a device for rotating the working part of the concave 8 around the longitudinal axis of the casing 7 (in particular around the axis 21). This device in the first embodiment (Fig. 2) has valves 23, closing the gaps between the solid part of the casing 7 and the ends of the concave 8. These valves have a cross-sectional shape in the form of an arc of a circle. Each valve 23 is provided with a rotational drive around the longitudinal axis of the casing 7, executed in the form of a lever mechanism. This mechanism has a guide lever 24 associated with the valve 23 (FIG. 3 at the end of which a battle 25 is installed located in the arcuate guide notch 26 of the guide bracket 27, as well as a rail 28, one end of which is pivotally connected to the lever 24, and the other is also pivotally mounted with a double-arm lever 29, the leading arm 30 of which is located outside the housing 5 for performing manual adjustment (rotation) of the valve 23. For automatic control, a servo motor 31 and grain pressure sensors 32 located below the bottom are provided 12 m.
    Instead of sensors 32, an inclinator 33 can be used (in the form of a parallel to determine the lateral roll of the combine. Sensors 32 or inclinator 33 are connected to the actuator 34 by means of a measuring transducer 35.
    For adjusting both valves 23, one can be applied.
    An inclining inclinometer 33. It is also possible to separately adjust the valves 23.
    In the second variant (FIG. 4) a device for rotating the working part
    5, the concave is made in the form of a mechanism for turning the casing 7 around its axis (in particular, around the axis 21, if the drum 6 is mounted coaxially with the casing 7). This mechanism contains
    10, four pairs of rollers 36 mated to the casing 7. The rotational drive of the rollers 36 can be made in the form of a reversing servo motor (not shown). The angle S is equal to 12015 130.
    The combine works as follows.
    Bread from the header 2 by the conveyor 3 and the beater 4 is fed to the threshing unit .1. During the threshing process, the grains that were released during threshing 8 are requested on the bottom 12, from which the sieve 15 is cleaned. To increase the degree of uniformity of grain distribution over the stepped bottom width 12 (and therefore the width of sieves 15), the concave 8 is rotated to the required angle of the working part. An effective working sector with an angle can be set by moving the valves 23. As shown in FIG. 2, this sector with angle S is set so that the left valve 23
    its lower part is immersed in the concave 8, while the right latch 23 is adjacent to the right outer edge of the concave 8 almost exclusively with its lowest edge. When the threshing drum 8 rotates in a counterclockwise direction, the left extension of the working sector, the concave 8 intersects approximately the left outer edge
    the stepped bottom 12, while the right edge of the working sector of the concave 8 intersects the right wall 20 at a certain height above the stepped bottom 12. Thus, it is achieved that the amount of grain discharging through the first third of the sector 8 is distributed on the left half of the stepped bottom 12, while the remaining part of the grain enters the right half of the stepped bottom. Due to the greatest degree of separation in the first half of the concave 8 (in the direction of rotation of the drum 6), an approximately uniform transverse distribution of the incoming grain over the entire width of the stepped bottom 12 is provided.
    The rearrangement of both valves 23 can be performed independently of each other, for example, manually or automatically. This is done by turning the two shoulders lever 29.,
    According to the second embodiment, depending on the expected uneven lateral distribution of the grain on the bottom 12, the concave 8 can rotate the whole casing 7, so that the operating sector of the concave can be set asymmetrically relative to the vertical plane 22. This setting can be made automatically according to the measurement signals from the sensors 32, or, respectively, inclinometer 33 (FIG. 2). The regulation of the sector of the concave 8 is carried out (FIG. 5) by means of the actuator 34.
    Thanks to the proposed installation of the working part of the concave, the threshed grain can be approximately evenly distributed over the ishrin
    cleaning, regardless of the direction of rotation of the threshing drum, or regardless of the side roll of the combine.
