Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to simplify the design. The swath header contains a cutting apparatus 1, a swath-forming conveyor 3, a reel 4 with tine arms 5 on which plates 6 are fixed to form a swath with shading of the plant's ear. The plates 6 are made in the form of a wedge with the top directed towards the outflow window of the header. Adjusting the position of the plates 6 is achieved by installing them on tines 5 with a given angle of inclination and position relative to the outflow window, as well as turning them along with tines 5. During operation of the header, the plates 6 separate the upper portion of the batch or the entire batch from the flow and raise it above the discharge window above conveyor 3. The new portion enters the free space in the connector of the butt part of the previous portion. Thus, the spike part of the plant is located inside the roll, and the bottom part is located above and below. 2 Il.

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to roller heads for separate harvesting of cereals.

The purpose of the invention is to simplify the design.

FIG. 1 shows the proposed header, a view from the side of the outflow window; in fig. 2 - the same, top view.

The roll header contains a cutting machine 1, a platform 2, a swath-forming conveyor 3, a reel 4 with tines 5 and a plate 6 for forming a roll with shading of the ear of a plant.

The plates 6 are made of thin-sheet material in the form of a dihedral wedge-wing, the top of which is directed toward the outflow window 7. The opposite side of the wedge is rigidly attached to the grab line 5 of the reel 4. Adjusting the position of the plates 6 is achieved by installing them on the rakes 5 with a given angle of inclination and position with respect to the outflow window 7, as well as their rotation together with the tines 5 by an eccentric mechanism (not shown) of the reel 4.

The roll forming mode is set by the working width, the speed of movement of the header and the rotational speed of the reel 4.

The proposed reaper works as follows.

Tines 5 reel 4 feeds uncut plants to cutting unit 1 and, after cutting, place them on the platform 2 with the butt part to the cutting unit

to the apparatus 1. The swath-forming conveyor 3 moves the cut plants to the ejection-f th window 7. In the zone of the window 7, the plates 6 act which separate the upper portion of the batch or the whole batch (depending on the purpose of the adjustments) from the flow and raise it above the discharge window above conveyor 3. The new portion enters the free space in the connector of the butt part of the previous portion. Thus, the spike part of the plant is located inside the roll, and the bottom part is located above and below, which provides shading of the ears and prevents them from interacting with the soil, from the possibility of germination of grains in the ear with moist soil, from mechanical and biological losses.

The harvester can be used for separate harvesting of grain crops in the southern arid regions of the country, especially seed plots, and in a set of machines of intensive technology.

Claims (1)

Invention Formula A 5 roll header, containing a cutting apparatus, a swath-forming conveyor, a reel with tine arms, on which plates are installed in the area of the outflow window to form a roll with shading of the plant's ear, which 0 in order to simplify the construction, the plates are fixed on tines along the outflow window and are made in the form of a dihedral wedge with the apex directed toward the outflow window.
