FIELD OF THE INVENTION The invention relates to agricultural machinery and can be used in the designs of combine harvesters. Inclined chambers of the combine harvester harvester are known, consisting of a body and a transporting body for feeding the stalks to the threshing apparatus.

However, in the event of increased grip on the header of the mounted type, the front axle of the combine is overloaded and the rear axle of the combine is underloaded.

The purpose of the invention is to reduce the moment created by the header relative to the axis of the front wheels of the combine by approaching to them the center of gravity of the header.

This is achieved by the fact that the body of the inclined chamber with the transporting body is made of two sections angled one relative to the other. In addition, in order to change the angle between the sections of the inclined chamber, they are articulated together.

FIG. 1 shows a tilted camera when the header is located in the working position; in fig. 2 - the same, with the header in the transport position.

The inclined chamber of the combine harvester consists of the upper section 1 and the lower section 2, connected by a joint 3. Spreaders 4 are connected to section 2. In the area of the joint 3, two hydraulic cylinders 5 of unilateral action are connected to two sections 1 and 2. To the bracket 6 is pivotally connected the platform 7 of the header. On the right and left sides of the receiving chamber are installed sections of the balancing mechanism 8.

Inside the top and sections 1 and 2

chain-slat conveyors 9 and 10 are mounted, which encircle the leading drums I and 12 and the driven drums 13 and 14, respectively, in a closed loop. To ensure the tightness of the articulated

the connections of the inclined chambers between themselves and the combine are made of flaps 15-17.

After connecting the upper section 1 of the spacers 4 and two hydraulic cylinders 5 and the flaps 15-17 to the combine, as well as after tensioning

sections of the balancing mechanism 8 platform 7 will be in the working position. In this case, the rods of the hydraulic cylinders 5 will be inserted. In this case, the upper and lower sections 1 and 2 will be tilted down,

the upper section 1 is inclined at a smaller angle than the nils section 2.

After the plants are fed by the screw 18 to the lower section 2, the chain-slatted conveyor 10 will grab them and transport them to the upper section 1, the conveyor of which will feed them to the thresher of the combine.

In order to lift the platform 7, it is necessary to push the stems of the hydraulic cylinders 5 by pumping oil into their cavity, while the upper section 1 from an inclined position will be raised upward relative to the driving drum I, which will lift the lower section 2 together with the platform 7. In this position the upper and lower sections 1 and 2 conveyors 9 and 10 will also be able to transport the stems to the threshing machine. The sections of the balancing mechanism 8 in this case do not change their force for holding the platform 7. The shields 15-17 will change their angle of inclination and ensure the tightness of the inclined chamber.
