Description

 The invention relates to agricultural production, in particular to seeders and combined units for sowing grass seeds in turf.

 Known is a combined unit for sowing grass in a turf containing a frame, support wheels, an active drive tillage device, a seeder with wheel carts pivotally mounted relative to the frame with coulters and rolling devices placed on them. The combined unit for sowing grass in the turf is equipped with a battery of disk knives mounted in front of a tillage device with an active drive and pivotally mounted on the frame, with a distance between the disk knives equal to the width of the processed strips (Patent RF 2108698, class A 01 B 49/06. Combined unit for sowing herbs in turf / Enikeev V.G. et al. (RF). - 3 pp., ill.).

 The disadvantage of this design is the complexity and intensity. This combined unit does not provide the water-holding capacity of the soil, the ability to absorb and pass water through into deeper layers, as well as the necessary soil gas exchange, when treating turf, the most suitable for the growth and development of grass seeds, since it does not make the turf deeper than the treated strip.

 The closest in technical essence to the proposed invention is a sodder seeder for strip sowing of grass seeds (RF Patent 2109424, CL A 01 B 49/06. Sodder seeder / Sysuev V.A. et al. (RF). - 5 pp.: ill.).

 The seeder has disk knives sequentially located on the frame, a milling section with working elements in the form of L-shaped knives, which has a mechanism for adjusting the depth of sod processing and is closed by a casing, in the back of which there are seed guides, a seed box with sowing machines and rolling rollers. On the outer sides of the disks of the milling section, ring-shaped knives are installed with an outer diameter exceeding the diameter of the circle described by the extreme points of the blades of the L-shaped knives and with an inner diameter equal to or greater than the diameter of the disks of the milling section.

 The mechanism for adjusting the depth of processing the turf is made in the form of a height-adjustable bracket with a support roller, on both sides of which are mounted disk knives located in the same planes with circles described by the extreme points of the blades of the L-shaped knives mounted on the inner sides of the disks of the milling section.

 The packer rollers are placed across the working width between the tracks formed by the ring-shaped knife and the circular knife.

 The disadvantages of this seeder are the high energy consumption of milling sod, high metal consumption, cumbersomeness, as well as the complexity of manufacturing ring-shaped knives of the milling section. In addition, the above seeder does not provide the water-holding capacity of the soil, the ability to absorb and pass water through into deeper layers, as well as the necessary soil gas exchange, when treating turf, the most suitable for the growth and development of grass seeds, since it does not make the turf deeper than the processed traces.

 The invention is aimed at solving the following problem: the creation of a compact seeder for sowing grass seeds in turf with low energy and metal consumption with high quality turf treatment, the use of which would provide the most suitable for the growth and development of grass seeds water-holding capacity of the soil, the ability to absorb and pass through itself water into deeper layers, as well as obtaining the most optimal soil gas exchange.

 The problem is solved due to the fact that the seeder for sowing grass seeds in the turf containing a milling section sequentially located on the frame with working elements in the form of knives, having a mechanism for adjusting the depth of the turf processing and closed with a casing in the back of which there are seed guides, a seed box with sowing machines and packer rollers, knives of the milling section are made S-shaped with the wing part bent down parallel to the strut.

 When operating a seeder for sowing grass seeds in a turf, knives of the S-shaped milling section cut the width and depth of the sod layer in the areas of the extreme points of the blades of S-shaped knives. Due to this, energy costs for the operation of the milling section are reduced, the quality of sod processing is improved, tear pieces of sod are not torn from the edges of the processed tape and, mainly, the soil’s water-holding ability, which is most suitable for the growth and development of grass seeds, is created, the ability to absorb and pass water through itself into deeper layers, as well as the necessary soil gas exchange of the meadow turf. Thus, the main part of the energy consumed by the milling section is directed to grinding sod blades with S-shaped knives. Seeds are sown in a layer of cultivated soil from a seed box by means of sowing machines and seed guides. Further, the soil in the treated strip of sod is compacted by packer rollers.

 Thanks to the installation of S-shaped knives with the wing part bent down parallel to the counter on the disks of the milling section, there is no need for a separate structural element for cutting the boundaries of the processed turf tapes, in the mechanism of its fastening on the frame or on the seeder working body.

 The combination of the above essential features provides a solution to the problem and significantly simplifies the design of the unit, reduces metal consumption, energy consumption and traction resistance of the seeder for sowing grass seeds in the turf, while the quality of the processing of turf and sowing seeds is quite high.

 The predominant embodiment of the bent portion of the wing of the S-shaped knife is offered in the form of a trapezoid.

 The advantages of performing the bent portion of the wing of an S-shaped knife in the shape of a trapezoid are the low energy consumption of sod milling, high wear resistance, low metal consumption, as well as ease of manufacture with high quality processing and obtaining the soil’s water-holding ability, ability to absorb and transmit, which is most acceptable for the growth and development of grass seeds. through itself water into deeper layers, as well as the necessary soil gas exchange.

 Thus, the set of essential features, taking into account the particular, predominant form of the structural design of S-shaped knives, will lead to the preferred form of the planter for sowing grass seeds in the turf.

 On figa, b shows the General structural and technological scheme of the seeder for sowing grass seeds in the turf; figure 2 - layout of the working bodies of the seeder for sowing grass seeds in the turf, top view; figure 3 - knife milling section, side view; figure 4 - diagram of the knife of the milling section.

 The seeder for sowing grass seeds in the turf contains a frame 1, on which there is a milling section 2, a seed box with sowing devices 3 and rolling rollers 4. The milling section 2 has working bodies in the form of two disks 5 from the outer and inner sides on which S -shaped knives 6, as well as a mechanism for adjusting the depth of sod processing, for example, in the form of a height-adjustable bracket 7 with a support ski 8. Each S-shaped knife 6 contains a rack 9, a wing 10 with a bent part 11, cutting edges 12, 13, 14 , 15 and the back edge 16. The height of the drive the portion 11 of the wing 10 has a trapezoid shape and is folded down parallel to the rack 9. The working parts of the milling section 2 are closed casing 17, the back of which are set semyanapraviteli 18. The ground pressure of the milling section 2 and packer rollers 4 is controlled respectively by springs 19 and 20.

 A seeder for sowing grass seeds in turf works as follows. When moving the seeder for sowing grass seeds into the turf, the S-shaped knives 6 of the milling section 2 move along an elongated cycloid (trachoid) 21, and the bent portion 11 of each knife cuts a layer of turf (a) along the length (AB) equal to or greater than the supply of turf on the cutter knife. Due to this, tapes of the processed turf with even lateral borders remain on the field surface. The depth of tillage is regulated by changing the length of the bracket 7 of the mechanism for adjusting the depth of cultivation of the turf. Seeds are sown into the treated soil layer from the seed box 3 by means of seed guides 18. The soil in the treated strip is compacted by packer rollers 4.

 The seeder for sowing grass seeds in turf is compact compared to the prototype, less energy-intensive and metal-intensive with high quality cultivation and obtaining the soil’s water-holding capacity, most suitable for growth and development of grass seeds, the ability to absorb and pass water through itself into deeper layers, as well as soil gas exchange of sod when sowing grass seeds.
