Description

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to agricultural harvesting machines.

The header is known, comprising a cutting apparatus, transverse conveyors, and an outflow window in which the working member is mounted rotatably 1.

A disadvantage of the known header is that the paddle beater does not ensure uniform distribution of the grain mass across the width of the outflow window. The tips of the beater blades capture the bulk of the grain mass coming from the transverse transport, and a smaller share of the grain mass goes to the middle part of the blades. As a result, less cut mass is supplied to the middle part of the outflow window than on the edges of the window.

The unevenness of the roll leads to grain loss. When direct combining uneven distribution

the grain mass across the width of the outflow window leads to its clogging and the combine getting out of order, as well as to the loss of grain during threshing.

The purpose of the invention is to reduce grain losses by uniformly distributing the grain mass across the width of the discharge port.

The goal is ensured by the fact that in the well-known device the working body is made in the form of an eccentric ramming caster, while the extreme end of the rakes are shorter than the middle fingers.

Claims (1)

Reaper includes frame 1 with outflow. window located against the inclined chamber 2 combine. The cutting element 3 is mounted on frame 1, behind which transverse conveyors 4 and longitudinal conveyor 5 are installed. In front of frame 1, a reel 6 is installed. than the extreme fingers 10. The beater 7 is fixed on the frame 1 by means of the rotary supports 11. The device operates as follows. The blades of the reel 6 bring the weight to the cutting unit 3 and after cutting it is laid on the header platform with transverse C and 5 longitudinal conveyors. When fed by the transverse conveyors f and the longitudinal conveyor 5 of the bevelled mass to the header outflow window located above the longitudinal conveyor 5 against the inclined chamber 2, the rotating beater 7 pushes the mass of tines 8 into the outgoing window. As the grain mass moves, transverse conveyors A firstly the extreme short fingers 10 shift the top layer of the fed mass to the outflow window, and then the middle long fingers 9 feed the bottom out layer of the mass into the outflow window. A uniform increase in the length of the fingers 9 and 10 from the edges of the tine 8 to its center ensures a uniform distribution of the cut mass across the width of the tine 8, and hence across the width of the outflow window Depending on the thickness of the cut flow on the conveyors VI 5, the position of the beater 7 change. For this, the beater 7 is raised or lowered, turning the supports 11. The position of the beater 7 relative to the wind shield is changed by moving the beater 7 along supports 11. The use of the proposed device reduces grain losses by uniformly distributing the cut mass across the outlet window. Claim of the Invention A harvester containing a cutting apparatus, transverse - rasportery, an outflow window in which a rotatable working tool is placed, characterized in that, in order to reduce grain losses by uniformly distributing the grain weight across the outlet window, the working member is made in the form of an eccentric rake beater, while the extreme fingers are tines shorter than the middle fingers.
