Description

The sowing section of the grain-fertilizer seeder belongs to agricultural machinery and can be used for sowing grain crops.

Known pneumatic seeder with a central metering system [RU 2457656 C2, AC 7/04 (2006.01), 08/10/2012]. It contains a centralized hopper with a dispenser, pneumatically connected through a seed distributor with openers mounted on the frame and including a stand, a cultivating paw, a seed stacker with a vertical channel and a comb-seal, one end of which is connected by a flexible connection, while the comb-seal is made of two parts , the first of which is secured from below on a cultivating paw, forming a trihedral wedge with it, the second part of the ridge-seal is made in the form of a plate.

The disadvantage of the proposed device is the lack of structural elements for local subsoil fertilizer application, in addition, the ridge-seal plate slides along the bottom of the furrow, makes contact with the seeds, which leads to damage, the coulter of the air seeder sows only one row of seeds.

Known opener with a device for fixing seeds in the furrow [RU 2274990 C1, A01C 7/20 (2006.01), 04/27/2006]. The coulter contains successively one after the other a ridge, coulter runners, a compactor, and earthing up to return the dry soil layer. The sealant is made in the form of two spherical disks located at an angle to the vertical plane. Zagortachi for returning the dry layer and mulching are made in the form of two brushes.

The disadvantage of this device is the lack of structural elements for subsoil fertilizer.

The coulter is intended for sowing seeds only on loose, leveled soils.

The objective of the utility model is to reduce costs and time during sowing.

For this, the proposed sowing section of the grain-seeder seeder includes: a mounting unit 1, two horizontal beams 2, two stops 3, braces 4, grain 5 and fertilizer 6 boxes, the base of the boxes 7, racks 8, the driven drive sprocket for sowing devices 9, sowing devices

10, chain 11, fertilizer 12, grain 13, roller 14, roller 15 lead, axis 16, lever 17, immersion depth scale 18, soil compactor 19, grain coulter 20, hinge 21, fertilizer coulter 22, stiffener 23 , sleeve 24, clamp of the fertilizer coulter 25, circular knife 26, flange 27, drive sprocket for the metering unit 28, axis of the circular knife 29.

The sowing section of the grain-seeder seeder consists of a fixing unit 1 with two parallel horizontal beams 2 rigidly attached, the beams 2 being connected to the fixing element 1 by two stops 3, and in the front of the beams 2, the axis 29 of the disk knife 26 with the flanges fixed on both sides is rigidly fixed 27. At the same time, a drive sprocket 28 is rigidly mounted on the axis 29, the drive of the fertilizer and seed metering devices 10, on which the chain is mounted

11, connected to the driven sprocket 9, mounted on the shaft of the sowing apparatus 10. The sowing apparatus 10 is rigidly attached to the lower part of the base 7 of the grain 5 and fertilizer 6 boxes. In addition, the bases 7 are rigidly attached to the rack 8 mounted on the horizontal beams 2, and between the horizontal beams 2 in the central part there is a sleeve 24 rigidly mounted, where the fertilizer coulter 22 with a stiffener 23 rigidly fixed in the rear part located in the longitudinal groove of the sleeve is placed 24, which is equipped with a clamp 25 of the fertilizer coulter 22, and to the lower part of the stiffener 23 by means of a hinge 21 a grain coulter 20 is attached, the lower end of which is bent back and equipped with a soil compactor 19 located above the con ta fertilizer coulter 22.

The sowing units 10 are connected by a grain wire 12 and a fertilizer wire 13, respectively, to the fertilizer opener 22 and grain opener 20. A roller 14 is placed between two horizontal beams 2 at the rear, the leash of which is rigidly attached to axis 16, hinged to one of the beams 2, and coaxially to the axis 16 to the beam 2 is rigidly attached to the scale of the depth of immersion of the roller, which is contacted by the lever lever of the leash 17 of the roller.

The operation of the seed section of the grain fertilizer seeder will be understood from the description and FIG. 1, FIG. 2, FIG. 3.

FIG. 1 - Sowing section of a grain-fertilizer seeder (side view);

FIG. 2 - Sowing section of a grain-seeder seeder (top view);

FIG. 3 - Sowing section of a grain-fertilizer seeder (section AA).

When lowering the mounting unit 1 with structural elements: two horizontal beams 2, two stops 3, braces 4 and forward movement, a circular knife 26 mounted on an axis 29 rigidly fixed between the horizontal beams 2 in their front part is immersed in the soil until it contacts flanges 27, rigidly attached to the disk on both sides of it. At the same time, a drive sprocket 28 for the sowing apparatus 10 is rigidly mounted on the axis 29, connected via a chain 11 to the driven sprocket 9. Fertilizers and seeds from the sowing apparatus 10, mounted under the fertilizer 6 and grain 5 boxes, are fed into the grain pipe 12 and the pipe 13 and further respectively, in the fertilizer coulter 22 and the grain coulter 20. Since the end of the fertilizer coulter 22 is located at the lower point of the disk knife 26, fertilizers are placed at the bottom of the furrow and sprinkled with soil under the influence of the end of the coulter 20, and then compacted with a sealant 19 , which is a continuation of the end of the grain opener 20.

Seeds emerging from the coulter 20 are guided through a compactor 19, which is a gutter, laid on compacted soil and covered with a loose soil layer, which is compacted with a roller 14. The piping 12 is placed in a sleeve 24, rigidly fixed in the middle of the beams 2, and in the sleeve in a groove is made in the rear part where the stiffening rib 23 of the fertilizer coulter 25 is placed, and the fertilizer coulter is held in the sleeve 24 by means of a latch 25, and a grain coulter 20 is attached to the lower part of the stiffener 23 by means of the hinge 21, and the upper khanism 30 adjusting the angle of inclination of the soil compactor 19 to the horizontal. The angle of inclination of the soil compactor 19 is changed by turning the grain opener 20 relative to the hinge 21, followed by locking the angle adjustment mechanism 30. The change in the depth of placement of fertilizers in the soil is regulated by changing the position of the fertilizer coulter 22 in the bush 24. No adjustment of the distance between the fertilizers and seeds is provided.

The use of the sowing section of the grain-fertilizer seeder will make it possible to carry out four technological operations in one pass, which will reduce the cost of money and time during sowing.
