Abstract

The invention relates to agricultural machinery and can be used for sowing, for example, germinated real potato seeds. The purpose of the invention is to improve the uniformity of seeding. The mixing chamber has a conical bottom 10, an intermediate perforated bottom P, installed with a gap in relation to the bottom 10 with an outlet nozzle 12 connected to the main outlet of the mixture in the opener. The cavity between the bottom 10 and 11 is communicated by the air pipe 6 with a source of compressed air. Compressed air is fed into the gap between the bottoms 10 and II into the holes of the perforated bottom 11 and the seeds are mixed in the volume of this fluid, where uniform mixing ensures the distribution of air supply through the gap between the bottoms, increasing towards the center. Blocking the perforation with seeds in front of the outlet nozzle 12 prevents the seeds mixed with the liquid from dropping from the bottom layer to the mixture outlet line. The operator opens the tap for the mixture to enter the coulter. 2 hp f-ly, 2 ill. i (L

FIG. 2

The image (ethene refers to agricultural machinery industry and can be used for sowing, for example, sprouted real potato seeds.

The purpose of the invention is to improve the uniformity of seeding.

FIG. 1 is a schematic diagram of a hydraulic split; in fig. 2 - diagram of the mixing chamber.

The hydraulic crop box (Fig. I) consists of a frame 1 on which mixing chambers 2 are installed, disk coulters 3, press rollers 4, reservoir 5 for liquid. The mixing chamber 2 is connected by an air pipe 6 to a compressed air source by a main line 7 for supplying liquid to a tank 5, a main line 8 for exiting the mixture with a disk opener 3. On line 8, a control valve 9 is installed.

The mixing chamber 2 has a conical bottom 10 (FIG. 2), an intermediate perforated bottom 11, installed with a gap in relation to the bottom 10 with an outlet nozzle 12 connected to the main outlet 8 of the mixture to the vomer. The cavity between the bottoms 10 and 11 is connected by an air pipe 6 with a source of compressed air.

Selka works as follows.

Before starting work, the operator fills from the tank 5 the mixing chamber 2 with liquid and a portion of seeds. From the compressed air source through the air duct 6, compressed air is fed under pressure through the air duct 6 under the pressure between the bottoms 10 and II, which passes into the holes of the perforated bottom 11 and mixes the seeds in the volume of liquid. Their uniform mixing is ensured by the distribution of the air supply through the gap between the bottoms;

filled up towards the center. The thickening of the perforation in front of the outlet nozzle 12 prevents the seeds not mixed with liquid from entering the bottom layer into the mixture outlet line 8. To bring the mixture into the coulter 3, the operator opens the valve 9. Upon completion of the seeding, the mixing chamber 2 is completely cleared of the mixture by draining it into the outlet nozzle 12 and line 8 along the slope of the perforated bottom 11, which eliminates the blockage of the next seed lot of the previous one.

Claims (3)

1.Hydraulic plant containing a mixing chamber for liquids and seeds, an air line with a source of compressed air, a reservoir for liquids, a line for supplying a liquid and a mixture outflow, characterized in that, in order to increase the uniformity of sowing, the mixing chamber is equipped with over its bottom with a gap, an additional perforated bottom with an outlet nozzle, the cavity formed between the bottoms communicates with a source of compressed air, and the outlet nozzle of the perforated bottom communicates with the main and mixtures thereof. 2. Section under item I, characterized in that, in order to improve the uniformity of mixing the seeds with the liquid, the gap between the bottoms of the mixing chamber is made variable, increasing towards the center, and the perforation is thickened towards the outlet. 3. Section according to claim 1, characterized in that, for the purpose of self-cleaning of the mixing chamber, the perforated bottom is made conical, with a slope to the outlet nozzle.
