Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to increase the reliability of work by preventing the winding of plant mass falling under the brackets 3 in the zone of the connection of the pipes 4 with the beams 1. The width of the brackets 3 is greater than the width of the beams 1. On the pipe 4, on either side of the beams 1, the washers 5 are freely put on 6. The sleeves 6 are provided on the side of the washers 5 with flanges 7 curved in longitudinal section, the outer diameter of which is smaller than the diameter of the washer 5. When the reel of the plant is in contact with the outer surface of the sleeve 6, they are displaced along this surface towards the washers 5, where they meet obstacles in the form of curvilinear flanging 7, which repel the stalks of plants. Therefore, they do not fall into the cracks located near the sleeves 6. 1 Il.

The invention relates to agricultural machinery, can be used in the reel of reaping machines and is an improvement of the invention according to the author. St. No. 898994.

The purpose of the invention is to increase the reliability of operation by preventing the winding up of the plant mass that falls under the staples in the zone where the pipes join the beams.

The drawing shows the proposed reel, a fragment and its tine.

The reel contains rays 1, on which pipes 4 are mounted by means of half-bearings 2 and brackets 3. The width of the brackets 3 is greater than the width of the rays 1, and on the pipe 4 the tines on either side of the rays 1 are loosely attached washers 5 and the bushes 6 are fixedly mounted from the side of the washers, 5 are matched fillets with a radius of curvature R with their main

fillets, which, when moving the reel, smoothly repel 6 stalks of plants from the sleeves and therefore they do not fall into the sh.eli located near them, which prevents the reel from failing. Making flanging 7 of a smaller diameter than the diameter of the washers 5 prevents the plant mass from jamming between the outer edges of these flanging and the inner surface of the staples 3. Fixed on the pipe

The 10 4 sleeves 6 do not rotate under the influence of contact with the washers 5 relative to this pipe and thus prevent the plant mass from being pulled. The sleeves 6 can be easily released and axially displaced by simply dismantling the corresponding bar tooth. This feature can be used if in very unfavorable cleaning conditions clogging will occur and it is necessary to clean the gap from

part of the flanging 7, the outer diameter of 20 plant mass. Making holes

which is less than the outer diameter of these washers. The sleeves 6 are fixed on the pipe with 4 bar teeth, threaded free ends 8 through openings 9 and 10 diametrically placed in these sleeves and pipe, and at various distances from the flanging end, 7 sleeves allow you to select the pair of holes required for securing these sleeves and ensure minimum clearance between flanging 7 and washers

9. These openings are made on some 25 5, which is even more preventable, which, when moving the reel, smoothly repel 6 plant stems from the bushes and therefore they do not fall into the sh. faces located near them, which prevents failures in reel work. Making flanging 7 of a smaller diameter than the diameter of the washers 5, prevents the plant mass from jamming between the outer edges of these flanging and the inner surface of the brackets 3. Fixed on the pipe

The 4 sleeves 6 do not rotate under the influence of contact with the washers 5 relative to this pipe and thereby prevent the dragging of the plant mass. The sleeves 6 can be easily released and axially displaced by simply dismantling the corresponding bar tooth. This feature can be used if in very unfavorable cleaning conditions clogging will occur and it is necessary to clean the gap from

9 and 10 at different distances from the end of the flange 7 sleeves, allows you to select the pair of holes required for securing these sleeves and ensure the minimum gap between the flanges 7 and washers

5, which is even more preventable

the flanges 7 spaced at different distances I and li from the end face. In this case, the fixing sleeves 6, the free ends of the 8 teeth, are passed through one 9 or the other 10 pair of holes.

The reel works as follows.

When harvesting and the work of the reel, thin stems of plants can fall under the brackets 1 having a width greater than the width of the beam 1 of the bracket 3. In contact with the outer surface of sleeve b, the plants are shifted along this surface towards the washers 5, where they meet with obstacles in the form of

Chews up.

Invention Formula Reel autom. St. No. 898994, characterized in that, in order to increase reliability by preventing the winding of plant mass falling under the brackets in the zone where the pipes connect with the beams, each sleeve on the side of the washer is provided with a flange curved in its longitudinal section, the outer diameter of which is smaller than the diameter of the washer.
