Description

2. The seed catcher according to claim 1, characterized in that the bottom is made with triangular reefs to move the seeds to the pneumatic line.

3. Seven catcher: in accordance with the fact that the sieve is made with a continuous preparatory section, the working surface of which is transverse trell194317

coal reefs to move the mass to be separated towards the exit end of the sieve,

4. This catcher according to claim 1, which is equipped with a drive chain endless element mounted above the sieve for moving the mass to be separated along the sieve.

The invention relates to the field of agricultural engineering, in particular, to the structures of these catchers of harvesting machines.

The purpose of the invention is to increase the reliability of the process, reduce seed losses and reduce metal consumption.

FIG. I depicts a cleaning machine with this catcher, general view; in fig. 2 - Sem the catcher of the harvesting mane, section; Fig. 3 is the same, the embodiment.

The device contains a pneumocamera 1 located behind the unloading window 2 of the harvester 3 of a self-propelled mower 4. The upper part of the pneumocamera 1 is equipped with a sieve 5. The bottom 6 of the pneumocamera i is equipped with triangular reefs to move the seeds to the pneumatic line 7. The pneumatic line 7 connects to the pneumocamera 1 with 8 seeds. and a fan 9. The walls 10 of the pneumocamera 1 are height-adjustable. The height of the walls is controlled by the height measuring mechanism 1I.

In another version of the manufacture of pneumocamera I, part I of resista 5 is made without the holes and stands within the limits of the pneumocamera in its front part. A closed chain contour 2 is installed above the surface of the pneumatic chamber 1 under the bottom of the self-propelled mower 4, equipped with a drive.

The device works as follows.

The harvested crop is mowed by the header 3 of the self-propelled mower 4 and through the discharge window 2 of the header 3 is fed to the pneumatic chamber 1. Caught on

the sieve 5 of the pneumocamera 1 mass under the action of oscillations moves along it, and the seeds threshed out by the working bodies of the header 3 are extracted from the mass. Having passed above the pneumocamera 1, the skewed mass is reduced to a roll.

Seeds, separated from the grass, are carried into the pneumatic chamber 1 through the sieve 5. Under the influence of vibrations of the pneumatic chamber 1, the seeds are transported inside it. by the triangular reefs of the bottom 6 to the place of connection of the pneumatic line 7 with the pneumatic chamber 1. The pneumatic flow created by the fan 9 picks up the seeds and seeds suspended in the suspended state that the pneumatic chamber 1 tosses by the bottom 6 and transports them to the accumulator 8 seeds.

The closed chain contour I2 mounted under the bottom of the self-propelled mower 4 contributes to the release of this catcher from the grass mass accumulated on the surface of the pneumatic chamber 1.

When mowing in rolls of various crops, the seeds of which differ in their physicomechanical characteristics, it is necessary to adjust the distance between the sieve 5 and the bottom 6 of the pneumatic chamber 1 in order to ensure optimal operating parameters of the seed catcher. The change of this distance is carried out by a screw mechanism 11 of changing the height of the walls 10 of the pneumatic chamber 1, while it is necessary to maintain the sealing of the non-cold chamber.

In an embodiment of the device, inserting the front part of the pneumatic chamber with a surface area made with triangular reefs allows preseparating the seeds from a pile of beveled garbage. This significantly decreases

the length of the pneumocamera, which allows an increase in the pneumatic effect on the seme on and improves the output of the seeds from the pneumocamera.
