    The invention relates to the field of agricultural engineering, in particular, to devices for lifting stalks from the ground. The invention makes it possible to simplify the fixation and transfer of the lifter from the transport position to the working position and back. The step lifter contains a lifting stem element 1, which can occupy different positions, two earrings 5, 6, communication bodies between the stem lifting member 1 and the bracket 8, and a return system 20. The lifting joint 1 contains a window 3 in which the turning axis 4 of the earrings 5 can slide. In the rest position, axis 4 is at one end of the window, 3, and in operation position axis 4 is at its other end. When moving around the field, a stem lifter mounted on a harvester copying the soil surface lifts the stalks from the ground. 2 hp f-ly, 7 ill.

    FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to devices for lifting a lagging crop, established by
    on cutting machines cleaning machines.
    The purpose of the invention is to simplify the fixation and transfer of the lifter from the transport position to the working position and back.
    Fig „1 shows a stem lifter,; FIG 2 is cut - section А-А in FIG. 1 on fig.Z - section B - B on FIG 4 - stem lifter
    with lifting element in the off position; in FIG. 3 — the stem of the elevator in the working position in FIG. 6 — the same, when the cutting apparatus is installed in the stop position or in the working position on the unevenness of the soil in FIG. 7 - the same, with the passage of obstacles with,
    The step lifter contains a stalk lifting element 1. In its front part it has the shape of a triangle with a sharp angle, the side of this triangle, facing the soil, contains a step 2 in its rear part. A slider (not shown) may be provided at the front end of the part t for supporting the soil0 The lifting element 1 has a window 3 that is linear and parallel to the direction of movement of the machine,
    The hinge axis 4 of the upper end of one earring 5 is slidably mounted in the window 30. This earring 5 is located in front according to the direction of movement of the machine relative to the second earring 6, which is installed with the possibility of rotation at its upper end on the axis 7.
    Both pivot earrings 5 and 6 serve as communication organs between the stem-bearing element-1 and the bracket 8. The bracket 8 comprises a front part with the foot extended back 9.. The front part of the bracket 8 contains a slot open upwards, bounded by two walls 10 and 119 between which the lower parts of sulfur 5 and 6b are inserted. In the walls 10 and I there are holes 12 and 13 for receiving the rotary axes 14 and 15 provided at the respective lower ends of the links 5 and 6.
    Step-lift element 1 contains a notch 16 and an axis 17 in the area of this
    the recess located between window 3 and the hole J8 under the axis 7, while the bracket 8 is equipped with the axis 19 located between the holes 12 and 13 under the axis 14 and 15, between parts 1 and 8 there is a return system, and this return system can contain elastomer 20 or. spring of appropriate shape, tensioned between axles 17 and 19.
    An adjusting screw 21 is provided at the front lower end of the bracket 8 to limit the course of the shackle 5.
    A means for attaching the stem lifter to the machine and containing a transverse branch 22 (FIG. 01) rigidly connected to the tab 9 is provided. Holes 23 are provided in this branch to receive fastening bolts 24 on both sides of the finger 25 of the cutting device of the machine.
    The window raiser works as follows.
    In the rest position (Fig. 04), the step-lift element 1 is locked both upwards and above the fingers 25 and the knife of the cutting apparatus of the machine passing through these fingers. Thus, it prevents wear on the soil and or unnecessary stresses caused by uneven terrain. When not in use, the Lift Element does not at all interfere with the work of the cleaning machine and does not interfere with the normal passing of the crop.
    The lifting member is transferred to the non-operating position in a manual manner, completely safe, without operator effort, and for a short period of time. When moving to the wrong position, you need to take the front part of the strap lifting element 1, lift it and push it back, while the device is automatically locked by transferring back the top part of the earrings 5 and 6 by turning around their axes 14 and 15 "Axis 4 earrings 5 slides back in the window 3, made in the floor lifting element 1 "Floor part 16, allows you to move earrings 5 and 6 and pass through the return system 1 20,
    In this case, the Liftgate element 1 is in an inoperative position, resting on the bracket 8. The inoperative position is firmly held in place by the return system 20.
    51
    The working position (Fig. 5), which allows the stem-lifting element 1 to slide under the dead crop, is obtained from the non-working position by pulling its front part and lowering it manually.
    Under the action of drawing forward, the lifting element 1 is raised under the action of sulfur 5 and 6, which, by turning around the axes 14 and 15, moves from a tilted position to the rear side to a tilted position forward
    The lifting member 1 moves, but remains in the upper position. Vigorous vertical pressing on its front end causes the axis 4 of the stud 5 to slip from the rear end to the front end of the window 3.
    In this case, the shackle 5 takes an inclined position toward the front, while the upper part of the shackle 6 recedes somewhat, which causes the inclined position of the forward lifting element 10 to appear. This inclination can be adjusted by operating the screw 21 on the stroke of the earring 5.
    When the driver of the machine sets the cutting unit on the ground, the front part of the lifting member 1 comes into contact with the ground. At this moment, the axis 4 of the earrings 5 slides back in the window 3, the axis 7 of the earrings 6 recedes somewhat and the position is automatically adjusted on the ground.
    In the working position (FIG. 6), the same position is when moving the machine with a slightly raised cutting unit, the front end of the lifting element 1 is in contact with the soil under its weight and under the action of the return system 20, the lifting sleeve 1 due to somewhat lifting that its front end rises above uneven terrain and has the same effect on the device as when installing the cutting unit on the ground when stopped, Axis 4 of the earring 5 slides back in window 3, axis 7 of the earring 6 somewhat it retreats, which allows the front end of the lifting member 1 to be vertically lifted and adapted to the soil.
    706426
    If the front end of the stem-lifting element 1 goes deep into the soil as a result of an improper maneuver or due to unevenness of the soil, hidden from the driver by lain vegetation, the force exerted in the longitudinal direction upon it by the machine advances
    the front of the window 3 in the axis 4
    5, inclined, in this case, forward. Steepleaver element 1 is fed back by the action of an obstacle caused by the advancement of the machine. At this moment, the axis 4 of the earrings 5 is fed back, the front part of the lifting element 1 is lifted along with itself.
