Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to increase the reliability of operation of the header and simplify the design. The wide-cut header consists of pivotally connected harvesting sections 1 on frames 2 with cutting units 3. Located between support sections 1, 4 reels 5 are connected by a mechanism 7 that synchronizes their raising and lowering. The latter is made in the form of two levers connected by a spherical hinge. The free ends of the levers have vertical axes mounted on the supports 4. When the header is working, the camber 1 and the sections 1 at the junction occur when the floor is copied by the relief, which are compensated for by dissolving and folding the arms of the mechanism 7. 3 silt.

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to wide-section section header reapers.

The purpose of the invention is to increase the reliability of operation of the header and simplify the design.

FIG. 1 depicts the proposed header, top view; in fig. 2 - synchronized, its mechanism, top view; in fig. 3 - the same, side view.

The harvester consists of pivotally connected harvesting sections 1 on frames 2 with cutting units 3. Located between adjacent support sections 1 of support 4

in the section remains set regardless of the position of the latter in the movement along the field. Accompanying work of the header, the collapse and convergence of the cutting sections 1 at the junction when copying the relief of the floor is compensated for by dissolving and folding the levers 9 of the mechanism 7. The deviations of the sleeves 11 of the levers 9 together with the supports 4 from the vertical plane are compensated by the ball joint 8.

The necessary simultaneous raising and lowering of the reel 5 of all the reaping sections 1 is carried out by injecting oil into the hydraulic cylinders 6 or by resetting it. However, inconsistency is possible.

Iotovil 5, supported by hydraulic cylinders 15 moving the reel 5 along the height of 6, is connected by a synchronizing mechanism by the action of the hydraulic cylinders 6 by compensating 7, made in the form of two arms 9 connected by a ball joint, the ends of which have vertical axes 10 in | a t in the support brackets 4. The levers 9 are made of different sizes in length and end with vertical bushes 11 under the axis of rotation 10. Pivoted 8

with the synchronizing mechanism 7, the lever 9 which perceives the forces arising at the same time.

Claims (1)

Invention Formula the ends of the levers 9 are different in design. So, one of them is made in the form of a sleeve with The wide header, containing the pivotally connected frames of the harvesting sections with cutting apspherical inner surface fixed under them under 25 pairs and supports of the reel, has a slotted through hole of the hinge 8. Forged by synchronizing their lifting and lowering the second lever 9 has a vertical which mechanism, characterized in that, the finger entering from the bottom into the hole of the shara in order to increase the reliability of the harvester 8.ki and simplify the design, each is located between adjacent harvesting sections. header following working qi E reel support is made of a conductive obrazom.dvuh parts, which are interconnected synchronizing their lifting and lowering mechanism made in the form of two interconnected ball joint levers, having free ends on vertical axes, mounted on The operation of the wide-cut header is associated with copying it by the hinged-connected harvest sections 1 of the topography floor. At the same time, in connection with the installation of the reel 5 on separate supports 4, the position of the motor: the fork 5 relative to the cutting unit 3 h35 parts x support. in the section remains set regardless of the position of the latter in the movement along the field. Accompanying work of the header, the collapse and convergence of the cutting sections 1 at the junction when copying the relief of the floor is compensated for by dissolving and folding the levers 9 of the mechanism 7. The deviations of the sleeves 11 of the levers 9 together with the supports 4 from the vertical plane are compensated by the ball joint 8. The necessary simultaneous raising and lowering of the reel 5 of all the reaping sections 1 is carried out by injecting oil into the hydraulic cylinders 6 or by resetting it. However, inconsistency is possible. the movement of the reel 5 in height under the influence of the hydraulic cylinders 6 compensates  the movement of the reel 5 in height under the influence of the hydraulic cylinders 6 compensates with the synchronizing mechanism 7, the lever 9 which perceives the forces arising at the same time. Invention Formula the movement of the reel 5 in height under the influence of the hydraulic cylinders 6 compensates A wide header, containing pivotally connected frames of the cutting sections with cutting apparatus fixed to them and reel supports interlocked by the synchronizing lifting and lowering mechanism, characterized in that, in order to increase the reliability of the operation of the header and to simplify the design, each piece of support.
