Abstract

Usage: the invention relates to agricultural machinery. Summary of the Invention; The header contains a transverse conveyor 3, under the h / upper branch of which there are inclined gable guides 5. A wall is formed between the cutting unit 1 and the front side of the header along the conveyor 3 and forms the bottom of the seed collector. From the rear side of the conveyor 3, protrusions 8 are arranged. In this case, between the wall and the front side and between the projections 8 and the rear side of the conveyor 3, slots are formed, connected to the collection. The collection of seeds is connected to the suction zone of the pneumatic conveying system. When the reaper head is working, the part is laid in the gutter zone, and the spike part is in the area of the protrusions 8.

Description

1

The invention relates to agricultural machinery, in particular to reapers for mechanized harvesting of seed crops of agricultural crops, mainly unevenly ripening and easy-sprinkling seed crops of leguminous crops and grass seedlings.

The purpose of the invention is to increase the completeness of the collection of biologically valuable, high-quality seeds.

FIG. 1 shows a general view of the proposed header, top view; in fig. 2 - the same, side view; in fig. 3 - header assembly with protrusions located behind the conveyor; in fig. 4 shows an embodiment of a header with an upstream movement of the blade; in fig. 5 shows an embodiment of a header for direct combining, i.e. when using a harvester on a single-phase method of cleaning.

The header contains a cutting device 1, a reel 2, a transverse canvas of a trans- port 3, in which under the upper branch 4 there are inclined gable rails 5. Between the cutting device 1 and the front, along the direction of movement of the header, the side of the conveyor 3 has a wall b, forming with the bottom of the collector 7 semes n gutter. From the rear side of the conveyor 3, along it and inclined towards the movement of the web of the conveyor 3, a series of projections 8 are installed, the height (hi, h2 and bz) of which increases in the same direction. Between the wall 6 and the front side of the conveyor 3 and between the projections 8 and the rear side of the conveyor 3 is made respectively of the slit 9 and 10, connected to the collection of 7 seeds,

On the protrusions 8, combing elements 11 are fixed, which are installed at an angle to the horizon in the direction of movement of the upper branch of the web of the conveyor 3 and can be made of rubber-fabric material or made in the form of an elastic element. The elongation of the elements 11 is increased in the direction of the drop edge of the conveyor 3,

To periodically clean the slit 9 from cutting particles of ears, etc. On the front side of the transporter 3, the cleaning elements 12 are fastened.

The surface of the collection of 7 seeds and wall b is coated with antifriction material. The collection of 7 seeds is in communication with the suction zone of the pneumatic conveying system 13.

Reaper works as follows.

When the header moves, the plants are mowed with the cutting apparatus 1 and fed to

conveyor 3. At the same time, the butt part of the stems is laid in the area of the gutter formed by the wall 6 and the bottom of the collection 7, and the spike - in the area of the projections 8. At the same time

due to the angle / inclination of the conveyor 3 and the movement of the blade along the inclined gable steps 5, local oscillations are caused in the upper working branch 4, which facilitate the transport of the selected seeds on the canvas to the projections 8, from where the seeds move along the surface of the collection 7 and conveyor 3 and connecting with seeds threshed under the influence of the cutting apparatus 1

and the reel 2. is directed by an air stream into a tank for seeds (not shown).

The movement of the ear of the plant along the protrusions 8 contributes to their oscillations in the vertical plane and

movements of plants relative to each other, with the result that seeds having a weak bond with the stem are separated without damage.

Seeding is enhanced by increasing the mechanical effect due to the increasing height of the protrusions 8, as well as the combing effect of the elements 11, the rigidity of which increases in the direction of the drop edge of the conveyor 3, i.e.

on the same side, the thickness of the cut plant mass increases.

The cleaning elements 12, in addition to preventing clogging by cut plants, of the slit 9 increase the intensity of sifting the isolated seeds on the front side of the conveyor 3.

The anti-friction coating of the surfaces of the collection of 7 seeds and the wall 6 helps to eliminate the blockage of the pneumotransport system 13 and to increase the productivity of seed collection per unit of time, as well as to reduce the wear of the associated work items.

Using the proposed header

will reduce the loss of seeds when harvesting leguminous crops and testicles of grass as at the time of laying the harvested crop in the roll, and in the selection of the roll.
