CO The invention relates to agricultural machinery, primarily to structural elements of the Reel Reaper adapted for harvesting leguminous and laid grain crops. A reel is known to have a tine made in the form of a shaft with a bar on which spring fingers are mounted, the bar connected to the shaft by means of a sheet rigidly mounted on the protrusions of the shaft, covered by the shaft and rigidly connected to the bar 1. The disadvantage of this design is that the bar unable to move relative to the shaft, spring fingers do not have the necessary rigidity to work on laid breads or leguminous crops, the sheet covering the shaft is rigidly fixed to the bar. Closest to the proposed technical essence is the rake of the reel, containing a tubular shaft on which the fingers are mounted, and a bar mounted so that it can move along the fingers 2. However, this rake of the reel is characterized by insufficient reliability of operation due to the gap between the tubular shaft with fingers and a bar, in addition, fingers do not have sufficient rigidity when working on laid breads and leguminous crops, there is no surface above the tubular shaft, I push it and with respect to attachment locations of the tubular shaft, and the latter in contact with the environment are easily damaged. The purpose of the invention is to increase reliability in operation. The goal is achieved by the fact that the rake of the reel, containing a tubular shaft, on which the fingers are mounted, and a plan, mounted for movement along the fingers, is provided with a casing for closing the gap between the tubular shaft and the strip, the latter having openings for the gauge and clamps for its fixing on them. FIG. 1 shows the depth of the reel, front view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

4 7 The rake of the reel contains a tubular shaft 1 on which the fingers 2 are mounted through the holes in the shaft. The bar 3 is mounted on the fingers 2, which are located in the holes 4 of the bar 3 and fixed to the fingers 2 by means of clamps 5. The rake has a cover 6 for closing the gap between the tubular shaft and the bar, which is made predominantly solid to prevent precipitation from falling on the tubular shaft 1 and bar 3 and winding vegetable mass on the reel. The casing 6 can be made of polystyrene and mounted on the strap 3 by means of a latch 7, passing through the grooves 8 of the slats 3, which are made to allow the casing 6 to extend relative to the attachment points of the tubular shaft 1 depending on the weight of the grain and climatic conditions. Plank 3 can be made of fiberglass. The device works as follows when working on leged breads or when harvesting leguminous crops, vegetation does not fall between the tubular shaft and the bar due to the presence of the casing 6. Fingers 2 placed in the holes 4 of the bars 3 ensure reliable capture of the plant mass without their deviation and when introduced into the soil do not break or bend. If it is necessary to adjust the extension of the bar 3 relative to the tubular shaft 1 by the latches 5, the fastening of the bars 3 to the fingers 2 is released and they are moved. Together with the strap 3, the casing 6 can be moved, thereby adjusting its extension with respect to the attachment points of the tubular shaft 1. The regulation of its extension can also be adjusted with the help of a clamp 7 and a groove 8 in the strap 3. Thus, the invention will improve the reliability by eliminating the gap between the tubular the shaft with the fingers and the bar, increasing the stiffness of the fingers, avoiding contact of the tubular shaft and the bar with the environment and ensuring the casing extends relative to the attachment points of the tubular shaft.
