Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular, to apparatuses for controlling the seeding rate in the field. The apparatus for sampling seeds when configuring a grain planter for the seeding rate comprises a seed collector and an apparatus for directing seeds to the seed collector. The seed-directing apparatus is made in the form of a tubular tee with a swing damper installed hingedly on the axis between the two inclined side branch pipes of the tee for opening or closing one of said branch pipes. One of the side branch pipes is therein configured to be connected with the seed collector, and the other is configured to be connected with the upper end of the seed line of the seeder. The vertical branch pipe of the tee is configured to be connected with the outlet funnel of the seeding apparatus of the seeder.

EFFECT: use of the invention provides a possibility of controlling the set seeding rate when the seeder moves directly on the field and adjusting the operating parameters of the seeding apparatus, if necessary.

Description

The invention relates to agriculture, in particular to devices for controlling the seeding rate in the field during the movement of the sowing unit.

A device for seeders for collecting seeds during testing is known, including a chute, a receiving container and a mechanism for raising it above the seed box of the seeder with tipping it in this position [USSR Author's certificate No. 372960 A01C 7/00: Adaptation for seeders for collecting seeds during testing . Appl. 08/19/1971, No. 1691715 / 30-15. Published 03/12/1973 Bull. 14. Authors: Podgorny Ya.M., Gerasimov L.P., Shevchenko V.G.].

The disadvantage of this device is the complexity of the design, the low reliability of fastening the elements of the pitched trays and the inability to control the supply of seeds by individual sowing machines for their subsequent adjustment to the seeding rate.

A sampler is also known, containing a tray, the lower part of which is attached to the seed tubes, three funnels installed under the three rightmost sowing machines of the seeder, a hook and a spring. When sampling, the tray is lowered and the seeds from the funnel fall to its bottom. In the working position, the funnels go into the tray [seeder grain-fertilizer row C3-3.6A and accessories. Operating instructions, approval sheet SZG 00.000A IE-LU, Kirovograd, 2004 - prototype].

Its disadvantage is the complexity of the design, the low reliability of fastening the funnels and the insufficient quality of control, due to the sampling of seeds only under the three rightmost sowing units.

The aim of the invention is to improve the quality of seeding rate control by providing a more efficient selection of seeds under any sowing machines on the move of the seeder, reducing labor costs and funds for this.

The achievement of the specified technical result is carried out by the fact that the seed guide of the device for collecting seed samples when setting the grain seeder to the seeding rate is made in the form of a tubular tee with a vertical branch pipe for connection with the outlet funnel of the seeding machine of the seeder and two inclined side pipes, between which a swing gate with the possibility of opening either one side pipe (for example, the left one) connected to the upper end of the seeder seed tube in the mode of sowing seeds through the coulter into the soil, then the other side pipe (for example, the right one) connected to the seed collector in the mode of selecting the sown seeds for the set number of revolutions of the support-drive wheel of the seeder.

The invention is illustrated by drawings: Fig. 1 shows a section of the body of the proposed device for collecting seed samples when setting up a grain seeder for a seeding rate; in fig. 2 - details of the device for collecting seed samples when setting the grain seeder to the seeding rate, complete with outlet funnel, seed tube and seed collector in the order of installation under the sowing machine of the seeder.

The device for collecting seed samples when setting the grain seeder to the seeding rate (Fig. 1) consists of a tee 1 with a vertical branch pipe 2, right 3 and left 4 side pipes, between which a toggle valve 6 is installed on the axis 5 in the upper part.

To be installed on the seeder, the device for collecting seed samples when setting the grain seeder to the seeding rate is equipped with a rubber coupling 7 (Fig. 2) for connecting the vertical pipe 2 with the outlet funnel 8 of the sowing machine of the seeder and the seed collector 9.

When installing a device for collecting seed samples when setting the grain seeder to the seeding rate for any sowing machine, its left branch pipe 4 is connected to the upper end of the seed tube 10 of the seeder, and a seed collector 9 is put on the right branch pipe 3 of it. is transferred to the open right extreme position for the passage of seeds from the sowing unit to the coulter.

Setting up the seeder for seed sampling to check the seeding rate of any of its sowing machines is carried out as follows. On the support-drive wheel of the seeder, a mark is made with chalk or paint. Further, when the seeder moves across the field, at a certain moment, the countdown of the number of wheel revolutions begins, and at the same moment, the flip gate 6 of the device for collecting seed samples, when setting the grain seeder to the seeding rate, is transferred to the extreme left position. Seeds from the tested sowing machine begin to flow not into the coulter, but into the seed collector 9, fixed on the right branch pipe 3 of the device. After the wheel has counted, for example, 20 revolutions, the overturn gate 6 of the device is moved to the extreme right position, and the seeds again enter the coulter. The seeds collected in collection 9 are counted, their number is compared with the required estimated number of seeds in the experimental sowing area. If necessary, the seeding rate is adjusted by the length of the working part of the metering coil by moving it in the right direction.

The coils of other sowing machines are set to the same length of the working part as in the tested sowing machine, or, if necessary, all sowing machines are subjected to alternate checks and adjustments.

The use of the proposed device for collecting seed samples when setting the grain seeder to the seeding rate provides for the determination of the actual number of seeds sown on the move of the seeder directly in the field while reducing labor and cost.
