(54) DEVICE FOR SEEDING SPROUTED SEEDS

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to devices for sowing germinated seeds.

A device for sowing sprouted seeds is known, which contains a hopper for 5 liquid-seed mixture, in the lower part of which a storage chamber is provided with an inlet and outlet openings with dispenser 1 installed in it.

The disadvantage of this device for sowing sprouted seeds is the additional flow rate for washing out the seeds from the roll cells of the collection chamber, which requires a special water tank. This leads to an increase in the mass of the machine and requires additional labor costs for the constant replenishment of the consumed water.

In addition, the intake of germinated seeds with liquid from the storage chamber by gravity leads to the fact that water, as a heavier component, flows out of the storage chamber faster, and the seeds, due to the presence of sprouts and strength

linger in the accumulation chamber and sem wire, which leads to uneven seeding.

The purpose of the invention is to increase the uniformity of seeding and reduce fluid consumption.

This is achieved by the fact that the device is supplied with a source of compressed air, and the dispenser is designed as a reciprocating movement of the slide valve with an annular groove that forms a storage chamber, the input and output openings of the storage chamber being shifted by one of the latter, and the accumulative chamber in the position of the spool, which overlaps its inlet, is connected by an air line to a source of compressed air.

FIG. 1 shows a device for sowing sprouted seeds, a slit; in fig. 2 and. 3 depicts the various positions of the device metering device and the process of sowing seeds. A device for sowing germinated seeds contains a hopper 1 in which a pressurized fluid with germinated seeds is dispersed. In the opening 2 of the lower part of the bunker case, there is installed a reciprocating moving valve 3, spring-loaded with spring 4 and kinematically connected with rotation of the cam 5. The valve has a collar 6 which forms an accumulation chamber bounded by the opening 2 and the edge cutting edges of the valve. The accumulation chamber has an inlet 7, cooCuienHoe with a bunker, and an outlet 8, communicated with the CM network, openings that are displaced relative to each other in the direction of movement of the zootnik by the magnitude of the latter's motion. G5, the leftmost position of the spool 3, with the inlet opening 7 (Fig. 2) closed, the accumulative chamber through the air duct 9 communicates with a source of compressed nostril (not shown), the pressure of which is larger than the fluid pressure in the hopper. The device for sowing seeds grown as follows. At the extreme disposition of the spool 3 accumulate on the meter. An annular groove 6 is connected to the inlet aperture m 7, and the air duct 9 is covered with a cylindrical part of the valve 3. In this position of the valve, the seed with seed through the opening 7 enters the annular groove 6 of the chamber. As the cam 5 acts. On the spool 3, the inlet 7 is partially closed, and the air line 9 for compressed air release partially opens with the spool 3 (Fig. 2). The air from the air duct 9, the pressure in which the large pressure in the bunker 1, through the annular groove 6 acts on the INFACE opening preventing the supply of fluid from the seeds to the annular groove 6, mixing up with the fluid at the outlet of the bunker into the hole 7 and disrupting the air sprouting seeds from each other. Ponadak) ILIII into the hole 7, the air prevents the seeds from being pinched by the edges of the hole 7 and the spool 3, because it eliminates damage. When moving to the left, the spool 3 sec. Displaces a part of the seeds from the annular groove 6 into the hole 8, and the air entering the outlet 8 pushes the seeds into this wire. At full stroke e and the leftmost position of the spool (Fig. 3), the latter displaces the remaining seeds from the annular groove 6 into the hole 8 and completely blocks the inlet 7 for a fluid with seed. All the air from the air duct 9 will pass through the outlet 8 in the passerie to transport the seed to the seven wire (indicated by the arrow). When the cam is turned off on the 1st (cam on the fi1 2, the cam is shown nJTpnx-iiyHK with a round) and the seeding process repeats. The invention consists of a device for sowing sprouted sm.n, containing a bunker for a fluid-seeded mixture, in the lower part of which there is an accumulation tank equipped with inlet and outlet openings with a metering device installed therein, characterized in that in order to increase the uniformity of sowing .m of the liquid flow, it is supplied with a source of compressed air, and the dispenser is made in the form of a fixed displacement of the spool with a collet hole, which will accumulate battening chamber, the one relative to the other h) nanravlenii movement of the spool at the stroke pos, 1ednego and ka.mera The accumulator in the position of the spool, perekryvayuschegg its inlet, duct communicates with a compressed air istochiikom collection chamber inlet and outlet are offset.
