Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to reduce grain losses due to the intensification of the release of ripe and near ripening seeds by the impact of working elements in the zone of discharge of the cut mass on the header platform. The reel consists of beams 3 with stops 4, tines in the form of a tubular shaft 6 with working elements attached to it. The latter are made in the form of a four-link hinge, one of the links of which is a spring-loaded blade 8. A torsion spring 12 is installed on the shaft 6, with a end rigidly fixed to the beam 3 at one end. A roller 16 interacting with the four-link is installed at its other end. When the header is operating, the blade 8 reel captures a strip of stalks and tilts the stalks during the cut. At the moment of cutting, when the blade 8 with a portion of the stems is in the zone of discharge of the cut mass onto the reaper platform, it makes a directed oblique blow to the ear of the plants, giving them more acceleration when falling onto the platform. Knocked out seeds get into this catching device. 3 il.

The invention relates to the agricultural industry of other mechanical engineering, mainly to the reels of headers, equipped with these tools for harvesting.

The purpose of the invention is to reduce losses due to the intensification of the release of ripened and ripening seeds by the impact of the working elements in the drop zone of the cut mass on the header platform.

Fig, 1 shows the proposed reel, side view; in fig. 2 - tine reel; in fig. 3 - mechanism for fixing the torsion spring.

The reel is mounted on the cutter 1, about | borudov nth sem catching device 2, and consists of beams 3 with fixed stops 4, leashes 5, tines, which are pipe shaft 6 with working elements installed on it, each of which is made in the form the four-arm, E of which the fixed link is the post 7, rigidly fixed to the tubular shaft 6, the middle link - the blade 8, spring-loaded to the rake by the spring 9, the rocker arms - the lower short pull of the 10 and the upper long pull of the 11. made of different sizes for application No oblique impact on the plants and their direction by the upper part of the blade 8 to the header platform 1. On the tubular shaft 6 a torsion spring 12 is installed, with one end 13 rigidly fixed on the beam 3, and the other end is a shank 14, at the end of which is fixed the holder 15 is mounted with a roller 16. The plate 17 is fixed on the blade 8, serves to protect it from shock impacts of the tail0

15 and acts as a track when the roller 16 rolls along it. The rack 7 has a window before the passage of the shank 14 with the roller 16 with the guides 18 in its upper part, as well as the brackets 19, between which a double-arm is mounted on the axis 20 21, spring loaded 22 towards the stop 23 to prevent it from turning in the opposite direction.

The reel works as follows.

When mowing the crop with the header 1, the blade 8 reel enters with the stem, captures the strip of stems, brings them to the cutting unit, supports and bends them over the platform of the header 1 during the cut. At the moment of cutting, when the blade 8 with a portion of plants is in the dumping zone of the cut mass on the header platform 1, the stop 4 on the beam 3 turns the double-arm lever 21, overcoming the resistance of the spring 22. The second lever arm 21 pushes the stem 14 of the spring 12 backward until until a sufficient clearance is formed for the passage of the shank 14. The released spring 12, straightening, strikes the shank 14 with the roller 16, which rotates in the holder 15, over the plate 17. At the same time as the spring 12 is twisted, the beam 3 rotates by certain angle and the abutment 4 out of engagement with the lever 21 which, rotating about axis 20 in the bracket 19, the spring 22 returns to its original position. Spring 12, rasp ml, interacts with the roller 16 with the plate 17 and moves the blade 8 from

falling on the platform exit of the roller 16 with the blade 8, the blade 8 in turn of the reel of the tubular shaft 6, forcing the rods 10 and 11 to rotate. When the latter rotate, the blade 8 makes a directed oblique blow to the spike part of the plants, giving them greater acceleration when cutting 1. After 9 returns the new position. Subsequently, the tubular shaft 6, using a leash 5 of an eccentric mechanism, rotates 360 ° relative to the beam 3 while simultaneously twisting the end 13 of the spring 12 by one revolution and bringing it into working condition. After the working process is completed with the reel blade 8 and the plant mass laying on the header platform 1, the reel is rotated by a certain angle, the next blade 8 captures the plant strip and the working cycle is repeated. All seized seeds fall on A reel containing beams with tungsten rotary shafts newly updated in them, on which working elements are fixed, each tubular shaft having a torsion spring fixed at one end to the beam, characterized in that, in order to reduce grain loss by activating the release of mature and on the verge of seed ripening by the impact of the working elements in the zone of discharge of the cut mass on the header platform, each working element is made in the form of a hinged four-link, one link of which is made in the form of dpruzhinennoy blade and the free end of the torsion spring is provided with a roller mounted to cooperate with a quadrilateral and fixing by a two-armed growling "with ustatrubcha-
