The node 23 of the transverse axis 24 has a pin 25 and pads 26, rigid 9 / attached to axis 24, while axis 24 is mounted in bearings 27 mounted on frame 17, and blocks 26 rest against stops 20. Right along the end of axis 24 is aligned with hole 28 in vertical longitudinal the support wall 2.9 of the non-existent bracket 30 fixed on the frame 17 in place stvom bottom member 3 in the upper part of the vertical continuation | No support wall. 29 there is a cutout 32 and a cutout 33. The rotary switch 34 is partially covered by a brace 30 and made in the form of a box 35, closed by a lid 36, inside which is located a circuit board 37 with a circuit and a brush assembly with a lever 38. The box 35 contains an inner wall 39 and a solid side wall 40. Assembled inner wall 39 is located parallel to supporting wall 29 of body 30 and has tides 41 and 42 with holes 43 and 44. Tide 42 passes through hole 28. Hole 44 ends with a coaxial labyrinth seal 45 aligned with it A base 39. The board 37 is mounted on the inner wall 39 with screws 46 in such a way that it closes the hole 43. The support plate 47 of the board 37 bears five output contacts 48 located along an arc, concentric hole 44 and the common contact 49, while the contacts 50 -52 are the same width and less than the width of the pull-out contact 53 and the pull-down contact 54. The contacts 50-54 are separated from each other by gaps 55 and connected to a socket 56, which hermetically closes the opening 43. The lever 38 includes a lever 57 of insulating material and a brush assembly 58 fixed on the lever with a screw 59. The lever 57 has a bearing element 60 and installed in the hole 44 of the housing on the cylindrical bearing element 61, the inner end of which is covered by a labyrinth seal 62, which coincides with the response labyrinth 45 of the housing. The beveled portion 63 of the lever 57 has two sleeves 64 spaced apart along its length 64. The sleeves 64, when the lever 57 rotates, coincide with the arcs along which the output contacts 48 are located. The floor of the cylindrical part of the bearing element 61 is covered by an internal wall 66 and forms a blind hole 67, in which the axis 24 is transverse, fasten with a pin 68. Copper-brush brushes 69 and springs 70 are installed in the holes 65 of the lever 57, and on the side of the springs 70 the holes 65 are closed with an electrically conductive plate 71 fixed by a screw 59. The cover 36 is fixed To the box 35 with 72 bolts and nuts, ensuring its tightness. The rotary switch box 35 is locked with an adjusting bolt 72. A selector switch 73 with a pointer 74 is installed in the operator’s cab, and a 75 wire harness with plug-in connectors 76 is connected to an outlet 56. The electrical circuit of the device is connected to the header 4 and respectively, the ground position of the cutting device 13 with respect to the ground comprises power sources .10 and 77, lifting circuit 78 and lowering circuit 79 having lift relay 80, lowering relay 81 and solenoid coils 82 and 83 th valve. The selector switch 73 has three contact segments 84-86 and contacts 01 b, C The mechanical indicator of the range of movement of the cutting device 13 contains a lever 87 connected to the axis 24, while the connecting rod 88 is pivotally attached to the lever 87, and the free end moves indicator ball 89 in channel 90 of a calibrated scale. The support ring 91 is installed between the cap 36 and the bearing element 60 of the rotary switch 34 and the contacts 92-101 are located in the selector switch 73. The device works as follows. The initial height of the header 4 is set relative to the surface of the floor by means of the selector switch 73. The floating flexible knife interacts with the stems of the crop to be harvested as the combine moves along the field. The cut-off hour of the plant moves along the transfer panel 14 and the bottom 16 to the processing units of the combine. In this case, several located in a row of sliders on the ground — sliders 22 copy the relief and serve as probes for raising and lowering the floating flexible knife 15 relative to the bottom 16 of the pick-up. The spring-loaded transverse axis 24, carrying rigidly mounted pads 2fr on itself, rotates with an angle, where the first position of the pad 26, which is currently at the highest point of the ground level and turning the same switch 34 of the rotary switch 34, causes the corresponding switching its contacts 49-54. The choice of the working height of the header 4 relative to the surface of the field is made by the selector switch 73. At the same time, the installed height of the header 4 is automatically maintained with the help of elements included in the electrical circuit. Thus, when the device is turned on by the selector switch 73 (position B), the contact segment 84 turns on the power supply of the device by contacts 92 and 93, while contacts 94 and 95 are closed by contact segment 85, contacts 98101 are closed by contact segment 86. In this case, the height of the header 4 is automatically maintained relative to the surface of the floor, corresponding to the angle of rotation of the brush bridge 3 (transverse axis 24) from the contact 53 to the contact 51 of the rotary switch 34. Changing the sector of the automatic height adjustment of the header 4 relative to the floor surface is done by setting the selector switch 34 at position B, C and D. The upper position of the combine cutting unit 13 is monitored at any time by the position of the indicator JIIap 89 in the channel 90 of the calibrated scale of the mechanical indicator, which is moved by the lever 87 connected to the axis 24 of the mechanical communication system. Compounds corresponding to the four positions A, B, C and D of the selector switch 73 are shown in Table (Fig. 9) and determine the control ranges of the displacement of the header 4. Each of the three contact elements 84-86 corresponds to the three poles of the selector switch 73 and has the arc is 90, and the angle of rotation between adjacent positions is 30. At the same time, the range of adjustment of the header in the vertical plane is greater than the width of the ranges selected using the selector switch 73. In some cases, determined by the nature of the crop or soil, it may be necessary to automatically adjust one of the extreme values of the total range of adjustment of the displacement of the header 4. For example, on the upper value, in which the floating flexible knife 15 is minimally displaced relative to the bottom 16 of the pickup. In this case, the total range is shifted within the floating. Displacement of the header 4 by setting the rotary switch 34 to another position. This is done as follows.
    The adjusting bolt 72 is loosened and the rotary switches are rotated in the slot 33. After which the adjusting bolt 72 is fixed. In this case, the motor contacts 48 are installed in a new position relative to the brush lever 38 and the regulation is carried out within the newly established range.
    The use of this device allows to significantly increase the reliability of the rotary switch and the machine as a whole.
    Comparison of the mechanical indicator readings and the position of the selector switch ensures that the operator is actively and quickly influencing the course of the cleaning process and improving its quality.
