The invention relates to agricultural machinery, devices for attachment of harvesting consoles to power means, in particular headers, especially for large gripping widths.

Attachment applicable rdk such harvesting machines as a mower and a forage harvester.

For a uniform and low sweat - 1) selection of harvesting material, especially for highly efficient harvesting machines that have a wide attachment, it must be created so that it provides the best copy of the soil. : It is known (patent GDR No. 75664 kp, A 01 D 55/28, 1972) attachment, in which the harvesting attachment is connected to the power tool by means of two movable sliding levers of paré placed 1C of two sides next to the feeding device. Lifting and lowering are carried out by means of acting on: the upper arms of the hydraulic cylinders. In order to regulate the pressure of the soil on: harvesting unit, upper arms: Connected to adjustable springs. In the working area, the upper levers, independently of one another, freely move upwards. In order to stabilize this system, below the upper arms between the harvesting unit and the energy tool, the lower driving arms are extended. The lower and upper arms are connected to each other, by means of connecting rods. As a result, the movement of the four-door broom is obtained in one plane.

Such a hinged device provides sufficient copying of the soil with a small width of the harvester attachment, since in this case only accurate longitudinal copying is required, and cross copying plays a secondary role. This minor cross copying is achieved using the gap between the driving levers and the power gap. KIM means.

A hinged device is known (GDR patent No. 127102, Cl. A 01 D 55/28, 1977) for easily removable harvesting stakes for street transport, which is equipped only with upper pivot arms. Instead of the bottom drive

There are cam paths with two levers with two rectangularly located one relative to the other rollers. Such a device provides transversely to the direction of movement a greater relative movement between the harvesting attachment and the energy means. But it has a flaw,

.JQ concludes that due to the presence of four rollers located in the B rolling bearings, and the fastening elements related thereto, it is difficult to manufacture. Also Togor

1J due to the presence of a large number of wearing parts, Oojibmoe need a number of spare elements.

The purpose of the invention is to

 to; for a harvesting console, in particular: atki, with a large working width, to create such a connection with an energy tool, which will ensure the least consumption of material to cost at a cost of

also a reduction in wearing parts and better soil replication with a harvesting attachment.

The invention is based on the task

3fs oz7l, a hitch attachment for the header of the harvesting mao: ians, which, when using the lower driving levers, will allow sufficient lateral movement between the harvesting attachment and the energetic, while achieving a quick and reliable attachment of the harvester to the energetic .

According to the invention, this is achieved by the fact that the lower driving levers consist of the connecting means moving in a vertical plane in the outer points of the energetic means; parts in which are located in the vertical plane mounted in the supports and on the sides in the horizontal plane, moving front parts. Pre-stressed cp50s are inserted between the connecting parts and the front parts.

Other elements, as a result of which, moving the sides of the vertical holes, the front parts in the unloaded state form straight connecting parts with the connecting parts. Fasteners, preferably made of tetrahedral steel, have openings in the supporting sections of the horizontal 31

for fastening the front parts with helical-calf holes. This detachable connection of the front parts to the connecting parts is achieved by the fact that the front parts are fitted with an overlay. The fasteners inserted between the plates with the help of the pin in their vertical holes are detachably connected to the front parts. The resilient elements are fixed with the help of the pads and side plates fixed on the plates. On the free ends of the front parts there are fixed support ears, through which communication is carried out with sheets placed in the lower zone of the harvesting attachment.

FIG. 1 shows the proposed device with a header and power means, side view j in FIG. 2 - the same, V1SC behind; in FIG. 3, the lower arm assembly, side view; in FIG. 4 the same as in FIG. 3, top view.

The power tool 1 in the supports 2 houses the upper pivot arms 3, which by means of the unloading springs 4 of the hydraulic cylinders 5 are connected to the power tool 1. On the front part of the levers 3 there are hooks 6, which are attached to the header 7 on two sides with bolts 8 on each side. At some distance from the upper arms 3, in the supports 9 of the energy means 1, movable lower driving levers are placed. These levers consist of the front part 10, the support tab 11, the elastic element 12 and the rear part of the connecting part 13 along the machine. On the front part 10 there is a support tab 11 mounted on the shield 14 of the header 7 and on the tool 1 side on the end of the front part 10 pads 15 are placed. Between the pads 15 and the plates 16 placed on the pads on the side plates 16, an elastic element 12 is installed. The rear part 13, which is connected to the horizontal support 9 of the means 1, has a vertically positioned hole through which the insert passes; the lining 15 of the front part 10 is a vertical pin 17. When the pin 17 is inserted into the vertical hole of the part 13, the elastic element 12 lies adjacent to the free end of the front part of the Yipodver20.

under the design of part 13 prior to tightening. The lower arms are hinged on the front parts 10 of the connecting rods 18 are connected to the upper arms 3. Since the prestressed elastic elements 12 are located between parts 13 and 10, these parts form

direct, being the lower driving lever.

The proposed device works as follows.

When the header 7 is attached to the vehicle 1, the hooks 6 of the upper arms first engage on both sides with bolts 8, and then when lifting the tab 11, the lower arms are connected to the shields 14 of the header 7. When transverse

skew headers 1 front 10

the lower arms move in the direction of the vertical pins of the pins 17 relative to the parts 13, while compressing the elastic elements 12. When aligning the header 1, they take the initial position under the action of the elastic elements 12.

Thus, a sufficient relative movement is achieved with respect to the energy means 1, and, consequently, an exact copying of the soil. Replacing worn parts is done by plugging the pins 17.
