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. (Aut. St. No. 1658848, IPC А01В 49/06).

The disadvantages of the known unit include the installation of a seed distributor on the rear of the protective casing. Due to the active work of the milling sections and the resulting oscillatory effects on the seed distributors, the uniform sowing of seeds over the area of sown strips is not properly ensured.

The closest technical solution is a combined unit for grass seeding, selected as a prototype, containing a frame with a hitch and support wheels, hoppers for mineral fertilizers and seeds with sowing devices, a gearbox, fertilizer and seed tubes, fertilizer and seed guides, milling sections, casings milling sections and rolls. Grass seeds coming from bunkers through sowing devices and pipelines to vibrating under the dynamic action of shields and springs to seed guides are scattered along the bottom of the compacted recesses (RU No. 160723 IPC А01B 49/06, А01В 49/00, 2016).

The disadvantages of the known design are low quality and high dispersion of seeds during sowing on the prepared for sowing strip.

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 combined unit for sowing grass in the turf of hayfields and pastures, including a frame with a hitch, support wheels, 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 rolls, according to a utility model, in the internal cavity of the nozzle-distributor there are dividing strips of seed flow.

The utility model is illustrated by drawings.

In FIG. 1 is a schematic illustration of a device; in FIG. 2 is a diagram of a seed nozzle.

The combined unit for strip sowing of grasses contains a frame 1, on which milling sections 2 are fixed, closed by casings 3, fertilized 4 and seed 5 bins, a gearbox 6. In the front of the unit in front of the milling sections 2 there are pipelines 7 with thread guides 8. On the rear wall of the protective casing 3, in its lower part, special pads are fixed 9. The seed ducts 10 with seed guides 11 are mounted after the milling sections 2 on a special frame 12. At the ends of the seed guides 11 there are nozzles for distributing seeds 13. In the inner section The fins of the dispensing nozzle 13 contain dividing strips 14 of the seed flow. Behind the nozzle-distributors 13 installed zagortachki 15 and rolling rollers 16. The pressure of the roller on the soil is regulated by a spring 17.

The proposed unit operates as follows.

When the unit moves across the field from the hopper 4, mineral fertilizers are scattered by fertilizer guides 8 onto the strip in front of the milling knives 2 through the sowing devices and pipelines 7. The knives of the 2 milling sections process the soil in the sowing zone with a strip and at the same time they close the tuks evenly into the treated layer. The protrusions of the pads 9 create a sealed recess. Grass seeds from the hoppers 5 through the sowing devices, seed tubes 10 and seed tubes 11 fall into the nozzle distributors 13. The flow of seeds coming from the seed guides 11, enters the dividing strips 14, nozzle-distributor 13, which ensure uniform distribution of seeds across the width of the seed, thereby ensuring even seeding along the aligned bottom of the sealed recesses. Zagortachi 15 align the near-strip rollers and close up the grass seeds sown with nozzle-distributors 13 with a uniform layer. Going behind the rollers 16 under the influence of pressure springs 17 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 and simplify the design of the combined unit.

Claims (1)

Combined unit for sowing grass into the turf of hayfields and pastures, including a hitch frame, support wheels, hoppers for mineral fertilizers and seeds with sowing devices, gearbox, fertilizer and seed tubes, fertilizer and seed guides, milling sections with knives, milling section housings with shields, pads and rolls, characterized in that in the inner cavity of the dispensing nozzle there are dividing strips of the seed flow.
