Description

The utility model relates to agricultural machinery, in particular to combined machines for strip processing of turf and sowing legumes in the turf of meadows and pastures.

Known combined machine for tillage and sowing, containing milling sections, protective housings, fertilizer and seed machines with seed distributors, packer rollers and zagrotachi. (A.C. No. 1658848, IPC A01B 49/06.)

A disadvantage of the known unit is that the seed distributor is mounted on the rear of the protective casing. Due to the active work of the milling sections, oscillatory effects on the seed dispensers occur, the absence of guides inside the dispensers and the difficulties with passing through the sowing channels of small grass seeds contribute to the uneven sowing of seeds over the area of the sowing strips.

The closest technical solution was chosen as a prototype combined unit containing a frame with a hitch, hoppers for mineral fertilizers and seeds with sowing devices, a gearbox, fertilizer and seed tubes, fertilizer and seed guides, milling sections, casings of the milling sections and rollers. Grass seeds coming from bunkers through sowing devices and pipelines to vibrating under the dynamic influence of shields and springs to seed guides are scattered along the bottom of the densified recesses (RU 160723, IPC A01B 49/06, A01B 49/00, 2016).

The disadvantages of the known design are the low quality of sowing, the high dispersion of seeds and the difficulty with sowing small seeds of grass on a strip prepared for sowing.

The technical task of the utility model is to simplify the design of the combined unit and improve the quality of sowing seeds on the soil.

The technical task is achieved by the fact that in the unit for sowing grass in the turf of hayfields and pastures, including a frame with a hitch, silos for mineral fertilizers and seeds with sowing devices, gearbox, fertilizer and seed tubes, fertilizer and seed guides, milling sections with knives , casings of the milling sections with shields, pads and coils, according to a utility model, the upper part of the vas deferens is equipped with a pipe for supplying air.

The utility model is illustrated by drawings.

In FIG. 1 is a schematic illustration of a device; in FIG. 2 shows a diagram of an air pipe.

The strip grass seeding unit contains a frame 1 with a hitch on which the milling sections 2 are fixed, covered by casings 3, fertilized 4 and seed 5 bins, gearbox 6, air compressor 7 with air ducts 8. In the front of the unit in front of the milling sections 2 are installed pipelines 9 with tap guides 10. On the rear wall of the protective casings 3, in its lower part, special pads are installed 11. The upper part of the vas deferens 12 is equipped with a pipe 13 for supplying air. Seed guides 14 are mounted, after the milling sections 2, on a special frame 15. At the ends of the seed guides 14 are installed nozzle distributors 16 seeds. Behind the nozzle-distributors 16 installed zagortachi 17 and the rolling rollers 18. The pressure of the coils 18 on the soil is regulated by a spring 19.

The proposed unit operates as follows.

When the unit moves across the field from the hopper 4, mounted on a frame 1 with a hitch, mineral fertilizers are scattered by fertilizer guides 10 onto the strip in front of the milling sections 2 through the sowing devices and pipelines 9. layer. The protrusions of the pads 11 create a sealed recess. Grass seeds from the hoppers 5 through the sowing apparatus fall into the vas deferens 12. The upper part of the vas deferens 12 is equipped with a pipe 13 for supplying air. The air flow created by the compressor 7, through the ducts 8 in the area of the air pipe 13 picks up small seeds of grass crops, contributing to the delivery of seeds to the seed bed. Excessive air pressure prevents small grass seeds from getting stuck on the bends of the vas deferens and contributes to a more even distribution at the moment the seeds enter the distributor nozzles. The seed stream coming from the seed guide 14, falls on the dividing strips of the nozzle-distributor 16, which ensure uniform distribution of seeds along the width of the sowing, thereby ensuring even sowing along the bottom of the sealed recesses. Zagortachi 17 align the near-strip rollers and close up the grass seeds sown with nozzle-distributors 16 with a uniform layer. Katochki 18 under the influence of pressure springs 19 compact the upper layer of the tape sowing, providing good contact of the seeds with the soil and the influx of moisture to the seed bed.

The introduction of a utility model will improve the quality of sowing grass seeds during strip sowing, simplify the design of the combined unit and improve the quality of the entire process.

Claims (1)
