Abstract

The device is designed to reduce chafing seeds and prevent losses of beaten seeds the central section of the scraper screw conveyor combine harvesters. At least above the center section of a worm conveyor there is a cover over the insertion fingers Barrier.

Description

(54) Equipment for reducing seed loss at the entry of the combine harvester

The device is designed to reduce seed shedding and prevent loss of seed shed through the central section of the scraper auger conveyor. At least above the central section of the scraper auger, a covering barrier is provided above the insertion fingers.

The invention relates to a device for reducing seed loss at the inlet of a combine harvester.

In the case of combine harvesters, the inlet of the material to be introduced in the central part of the harvesting table is designed so that the auger-type conveyor is provided with a cylindrical section with insertion fingers in the middle. They rotate into the harvested mass when the auger conveyor rotates, releasing seeds from the plants. If the amount of straw mass is sufficient, this deficiency is not a major defect, since the broken seeds remain wholly or predominantly in the straw and get further into the machine. However, if the amount of straw mass is small in relation to the amount of seed shed, or if a harvester harvester is used, the released seeds get out of the area of the harvesting table, generating considerable harvest losses.

This disadvantage is overcome by the device for reducing seed loss at the inlet of the combine harvester according to the invention, characterized in that a covering barrier is provided above the insertion fingers at least above the central insertion section of the rake screw conveyor.

The device for reducing seed loss at the inlet of the combine harvester of the present invention both reduces seed breaking and; it reliably prevents the possibly spilled seeds from being thrown out of the area of the harvesting table, so that the released seeds, along with the straw mass, reliably reach the machine.

Claims (2)

SUBJECT An apparatus for reducing seed loss at the inlet of a combine harvester, provided with a harvesting table with a scraper auger equipped with a central insertion section, characterized in that at least above the central insertion section (4) of the scraper auger conveyor is shown schematically in the attached drawing, FIG. Fig. 2 is a partial plan view of the device according to the invention. The combine harvester table 1 (not shown) is equipped with a shrinking screw conveyor 2, which is equipped with a central insertion section 4 with insertion fingers 5 at the center of the machine entrance 3. At least above this central insertion section 4, or to a greater extent A covering barrier 8 is provided by the conveyor 2, which is either fixed or fixed by means of hinges 7 to the harvest table 1, and can be provided with an adjustable positioning fixation 8 or with an adjustable or fixed stop (not shown). The device according to the invention functions as follows: When the harvested material is fed to the shrinking conveyor 2 and thus to its central insertion section 4, the harvested material comes into contact with the insertion fingers 5, which in each case necessarily releases some seeds. However, because of the use of the cover barrier 8, the insertion fingers 5 do not beat the harvested material from below but practically only from above in the lower part of their path, thus greatly reducing the total amount of seeds released and remaining loose seeds directly in the transported material. 5 cast directly down into the straw mass. The cover (6) is provided above the insertion fingers (5). Device according to claim 1, characterized in that the covering barrier (6) is fixed by hinges (7) to the harvest table (1) and provided with an adjustable fixation (8).
