FIELD OF THE INVENTION The invention relates to agricultural machinery industry and can be used in the construction of headers for harvesting agricultural crops.

The purpose of the invention is to reduce crop losses.

The drawing shows a diagram of the proposed stseplepodnik, installed on the cutting unit.

The step lifter has a base 1, which is attached to the finger bar 2 by a bolt connection 3. On the base 1 there is mounted a brace element 4 that connects it to the toe of finger 5. In the front part of the stem lifter there is a toe 6 to which the lifting feather 7 is attached.

The feather 7 in section A from the nose 6 to the vertical plane passing through the toe of segment 8 is made along the curve of the equidistant path of movement of the rake 9 reel, and in section B from the vertical plane passing through the toe of segment 8 to the rear end of the feather 7, performed along the curve of the bulge up. The radius of curvature of the lifting pen 7 on section B is smaller than the radius of curvature of section A.

The window raiser works as follows.

When moving across the field, fallen and entangled plants are picked up by the toe 6 and raised upwards by lifting feather 7. At the same time, over the lifting feather 7, the rakes 9 of the reel are moving, which contribute to the uniform movement of the plant weight along the lifting feather without jamming and congestion to the segment 8 of the cutting unit. After cutting, the vegetable mass progresses along plot B and freely comes off the stem lifter.

In the case when the amount of plant mass increases on the lifting feather 7, it bends under the action of the increasing load to the brace element 4 and the further deflection ceases.

Claims (3)

1.Wheel lifter mounted on the cutting unit under the reel, wedge-shaped, the base of which is made of spring material and attached to the finger bar of the cutting segment apparatus and to the finger using a clamp element, and the upper part is made in the form of an elastic lifting pen characterized in that, in order to reduce crop losses by improving the transport of stems, a lifting feather in the area from its toe to a vertical plane passing through the toe of the cutting device segment The curve is made along the curve of the equidistant path of movement of the tines of the reel, and in the section from the vertical plane passing through the toe of the segment to the rear end, the curve is curved upwards. 2. The window lifter according to claim 1, characterized in that, in order to prevent congestion from cut plant mass, the radius of curvature of the lifting pen in the section from the vertical plane passing through the toe of the segment to the end is less than the radius of curvature of the lifting pen from its toe to vertical plane. 3. Window lifter according to claim 1, characterized in that, in order to limit the deflection of the elevator feather down, the surface of the clip-like element facing it is designed as an emphasis.
