The slats 10 on the conveyor 2 are installed on no more than half of its length, and on the conveyor 3 on the entire length. The lifting cylinders 7 of the conveyors 2 and 3 are connected to the frame 1 by one end and the other to the stop arms 11. In the working position, the stops 1I do not act on the platform 13, which allows the cutting unit 4 to copy the relief of the floor in case of copying elements 6 in the hollows.

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to reapers for mowing plants.

The purpose of the invention is to improve the copy quality of the relief of the floor and the formation of a cross roll.

The drawing shows the proposed .ma, header, side view.

The roll reaper consists of a frame 1, a main storage 2 pivotally connected to it and an additional unloading 3 conveyors, a cutting unit 4, a reel 5, copying elements 6, hydraulic lifters 7 lifting conveyors 2 and 3, balancing devices having a belt 8, and supports wheels 9. The load-carrying elements in the form of strips 10 on the conveyor 2 are installed no more than half of its length, and on the conveyor 3 - along the entire length. One end of the hydraulic cylinders 7 are connected to the frame 1, and the other to the stop arms 1, which are hinged on one side to the stand 12 welded to the frame 1, a. on the other hand, 7 platforms 13 of conveyors 2 and 3 abut. In the working position, the stop 11 does not act on platform 13, falls slightly below it. This allows dir; In this case, make a copy of the floor surface in case of copying elements 6 in the hollows.

The adjacent ends of the conveyors 2 and 3 are hinged to the bracket 14, welded to the frame 1, and form an obtuse angle with the top between them.

When mowing, the plants are captured by the reel 5, fed to the cutting apparatus 4, and after mowing they are laid on the platform 13. With the start of movement, the header begins to rotate and the conveyor 2, which is assigned one of the selected modes of speed of movement. In the process of operation, the strips 10 of the conveyor 2, going out from under the platform 13, seize the plant stalks laid on the platform 13, move them in the direction opposite to the direction of movement of the header. At the same time, the newly cut plants continue to lay down on the vacated space of the conveyor 2. Thus, the entire length of the platform 13 is filled. At the end of the filling cycle, the last plank 10 starts to go up. At this time, both conveyors 2 and 3 are turned on in the unloading mode, the speed of their rotation becomes equal to the speed of movement of the header. At the same time, the vegetative mass, descent from the conveyor 3, is placed on the stubble.

Thus, the unloading of the mass can be performed regardless of the operation of the conveyor 2. This allows you to automate the switching of the conveyor 2 from the accumulation mode to the mass transfer mode to the conveyor 3 using sensors and an actuator (not shown), and turning on the conveyor 3 to the unloading mode for example, using a photo relay or other sensor with manual or mechanical switching from one operating mode.

facing up. The hinges are 15 flat-40 presses in another (not shown). In trance

The front end of the conveyor 2 and the rear end of the conveyor 3 are significantly extended to allow the header to overcome the ground and other unevenness of the floor without disturbing the cutting process

Valkova reaper works as follows.

Conveyors 2 and 3 by hydraulic cylinders 7 are lowered to the surface of the floor, mounted on copying elements 6, the pressure of which on the soil is adjusted to the required value by means of a balancing device. The conveyor 2 is installed so that the slats 10 are located under the platform 13. In this position, the header should be before the beginning of the gagging head.

Claims (1)

tailor position of the header is translated by lifting the outer ends of conveyors 2 and 3 by hydraulic cylinders 7. Claim 1: A roll machine comprising a frame with supporting wheels, a cutting unit, a reel, a swath-forming conveyor with load-carrying elements located on a site less than half its length, and a mechanism drive, in a manner consistent with the fact that, in order to improve the quality of the relief copying of the floor and the formation of the cross roll, it is equipped with a carrier located behind the main additional conveyor f ° elements along the entire length, the adjacent ends of the conveyors scharnirno fixed relative to the frame with voz31396997 .4 the possibility of movement in the vertical 3. The harvester according to claim 1, about the T l and h th plane and with the formation of an angle between-schA so that in the area of joining do them with Bepi -HHcfr, directed upwards. Transporters are equipped with balance 2, The harvester according to claim 1, differs with lifting devices, and is free from the fact that the angle between the trans-ends of the conveyors are equipped with copers and filled with blunt-sounding devices.
