Description

This invention relates to the field of

agricultural machine building, in particular, to the hitch of the side header of the wide-grip harvesting complex.

The aim of the invention is to increase reliability and reduce metal consumption.

Fig. 1 shows the wide-sweeping cleaning complex in the transport position; in fig. 2 and 3 is a diagram of the transfer of the complex from the transport position to the working position; in fig. 4 shows the complex in the working position in FIG. 5 is a view along arrow A in FIG. 4 In FIG. 6 is a view along arrow B in FIG. five.

The hitch of the side header of a wide-range harvesting complex, containing a self-propelled energy module 1, on the frame 2 of which the front of the front 3 is hung and two side 4 and 5 header, includes connecting bars

6 and 7 with swivel wheels 8 and 9, connecting bars 6

7 by means of horizontal hinges 10 and 11 are supported on L-shaped pins 12 and 13, which are fixed by the ends of the shoulders 14 and 15 on the frame 2 by means of a vertical hinge 16 located on the rear cross member 17 of the frame 2.

The other shoulders 18 and 19 of the lips 12 and 13 are equipped with locking devices for the working position of the coupling in

grips 20 and 21. In the rear part of the knuckles of snits 12 and 13, locking devices for the transport position of the hitch are made in the form of stops 22 and 23 and counter gripping 24. Shoulders 14 and 15 of shades 12 and 13 are box-shaped beams made of bent walls 25 -28 of sheet steel interconnected by welding. A fork 29 of the vertical hinge 16 is attached to the end of the beam, and the other end is mated with a cylindrical shoulder 18 or 19, the Fold line 30 of the wall 25 is separated from the fold line 31 and the other wall 26 by a distance exceeding the sum of the bend radii of these walls. Similarly, the fold line 32

separated from the fold line 31 by a distance greater than the sum of the bend radii of these walls.

The transfer of the wide-range cleaning complex to the transport position is carried out as follows.

The front header 3 and side header 4 and 5 are servo-hydraulically mounted in the transport position. One of the grippers is then opened, for example, the gripper 20 of the right-hand cut 12, and the module 1 is pushed forward with a turn to the left until the stops 22 and 23 of the blades 12 and 13 touch, and the gripper 21 of the other-cut 13 is opened and then with connecting bars mi 6 and 7 and header 4 and 5 form a rigid semi-trailer.

Making the box-like part of the fits with the displaced inflection lines of the walls allows to increase the rigidity of the shoulders of the fits by at least 30%, due to which it is possible to eliminate the danger of cracking. Removing internal stiffening ribs from cavities ensures a reduction in metal consumption by 40 kg per unit and labor intensity of manufacturing by no less than 2 times.

Claims (1)

Invention Formula The hitch of the side header of a wide-range harvesting complex, including an L-shaped taper, fitted with locking devices of the working and transport position, made in the form of a box beam bent in several planes, and connecting bars of the header, fitted with support wheels and mounted on the lath using horizontal hinges, differing - so that, in order to increase reliability and reduce metal consumption, the bending line of any wall of the box girder spits away from the bending line of another adjacent or adjacent out of its lying wall for a distance greater than the sum of the radii of these walls. one View A eleven 3D 32 Riga 5 30 Riga.v View b
