The invention relates to agricultural production, in particular for drills and combined units for direct band seeding in stubble and sod.
Known to be installed separately on each Shoe milling section of the safety clutch of the company Staub (France) with a radial conical Cams. Milling section consists of a housing in which is located a drive shaft, resulting in a rotation by a bevel gear driven shaft with spline shank for connection with the crosses of the relief devices. Torque from the driven shaft is transmitted to the hub of the rotor cutters due to being in the guide cones crosses plungers, which are under the influence of springs are inserted into the recesses of the hub. At the meeting of the G-shaped rotor blades with an obstacle plungers are displaced from the recesses of the hub, while the shaft continues to rotate (Yatsuk, H.E. and other Rotary tillage machinery. - M., "engineering", 1971. - 256 S. - P.236...237).
The disadvantage of this device is that when entering the l-shaped knife into the soil or when they meet with an obstacle the full force of the blow before the trip a safety clutch assumes the knife itself, which reduces its life due to exposure to intermittent shock loads, and also leads to excessive energy consumption for milling.
Closest to the technical essence is the seeder for sowing grass seed in the turf SDKP-2,8 containing consistently located on the frame hole covers and having a mechanism for adjusting the depth of the milling section with openers in the form of disks with G-shaped knives, a hopper for seeds and fertilizers with metering devices and their drive, the seed and calopresti, seed and tokenprivileges, the drive wheels and packer rollers. The drive of the milling section is maintained through the mechanism of the transmission of the planter from the tractor PTO. To prevent damage to the tractor PTO and transmission elements of the drill SDKP-2,8 between the propeller shaft and the transmission planter set safety coupling with shear pins (Vasilyev, Addario, Ammeter, Astasenkov. Technology and technical means for band sowing grass seed in the turf (recommendations). - Kirov: agricultural research Institute of the North-East, 2000. - P.45...47).
The disadvantage of this machine is that the seeder for sowing grass seed in the turf SDKP-2,8 is equipped with a safety device that is designed for much higher loads than the maximum allowable force on the l-shaped knife, and therefore does not protect l-shaped knives milling sections from damage. The breakdown of l-shaped knives at the result, until the detection of a malfunction, deterioration of grinding stubble or sod and thereby reduces the quality of the direct band seeding. In addition, the rigid attachment of l-shaped blades reduces the lifetime of their service due to exposure to intermittent shock loads at the entrance of the knives in the soil and increases the energy consumption for milling.
The invention is aimed at solving the following tasks: improving the quality of tillage and direct band seeding in stubble and turf, increasing the lifetime of the l-shaped blades and lower energy milling.
The problem is solved due to the fact that the band seeder sowing containing consistently located on the frame of reference-drive wheels, milling section having a mechanism for adjusting the depth of processing and the closed casing, the output shaft is installed in the working bodies in the form of disks with G-shaped knives, a hopper for seed sowing apparatus and the actuator, the VAS deferens, semenprivate and packing rollers according to the invention, each working body of the milling section contains the safety coupling, consisting of the leading half-coupling mounted on the output shaft of the milling section and having a radial projections on the outer surface, slave coupling with radial holes, what vtoroy are disks with G-shaped knives, the intermediate sleeve, made with radial slots and with diametrically spaced recesses on the outer surface, and they are mounted so that each of the radial projections leading coupling is located in a respective radial slot of the intermediate sleeve and between the side opposite to the direction of rotation of the working body, a compression spring, while the slave coupling is connected to the intermediate sleeve spring-loaded stoppers mounted in radial holes slave coupling and diametrically located recesses intermediate sleeve.
When the planter band sowing working bodies milling sections, made in the form prescribed by the slave coupling drive with G-shaped knives, shredded strips of soil monolith stubble or sod. Thus from the hopper to the seed through the seed metering apparatus according to the VAS deferens and amanpreetalam in the layer of treated soil to a predetermined depth serves grass seed. Next, the soil in strips sealed packer rings.
When milling the strips of soil at the time you enter the l-shaped knife in stubble or sod, when the load on the l-shaped knife rises sharply from zero to a maximum, a compression spring installed between the radial protrusions of the leading coupling and radial walls is different slits intermediate sleeve from the side, opposite to the direction of rotation of the working body, smooth the shock load on the l-shaped knives. This allows to increase service life l-shaped knives, and also provides the opportunity to reduce the energy intensity of milling soil by reducing the maximum circumferential force acting on the knife, 2,0...2,5 times (Yatsuk, H.E. and other Rotary tillage machinery. - M., "engineering", 1971. - 256 p. - C.175).
In the case of a meeting of G-shaped knife with the subject, hardness and strength greatly superior to the corresponding soil parameters, compression springs are compressed to the choice of the gaps between the coils of the spring, which is the beginning of the release spring-loaded stoppers driven half-coupling of the respective recesses diametrically intermediate sleeve, i.e. slave coupling starts to rotate relative to the leading coupling. When this breakdown of l-shaped blades is eliminated. After contact with an obstacle end, the stopper slave coupling under the action of the springs will be included in diametrically deepening of the intermediate sleeve, and the milling process of the soil will resume. Protection l-shaped knives working bodies milling sections from destruction when they meet with an obstacle can improve the quality of the soil, and hence the direct band seeding, because they always supported the need for the th degree of crumbling soil, which depends on the number of l-shaped knives, mounted on the working body of the milling section. Thus, the use of a safety clutch in the design of the planter band seeding helps to soften the shock load on the l-shaped knives and prevent their destruction when they meet with obstacles in the soil, which significantly increases the service life of l-shaped knives, reduces the intensity of tillage and improves the quality of tillage and direct band seeding in stubble and sod.
The combination of the above existing signs provides quality tillage and direct band seeding in stubble and turf, increasing the lifetime of the l-shaped blades and lower energy milling.
The proposed ratio at which the total stiffness of the compression spring located between the radial protrusions of the leading coupling and the walls of the radial slots of the intermediate sleeve, when their largest installation length equal to the average cutting force soils with l-shaped blades of the working body of the milling section, and the total stiffness of these springs are at maximum compression under load corresponds to the full release of the brakes slave coupling of diametrically spaced recesses intermediate sleeve and at the same time the maximum allowable force on the-shaped knife of the working body of the milling section, is the predominant form for the selection and execution of compression springs for safety clutch and allows the safety clutch smoothly with mode damping of shock loads on the shutdown mode of the working body of the milling section of the transmission mechanism of the planter band seeding.
Thus, the set of essential features with regard to private predominant form meaningful implementation of the safety coupling will lead to a preferred form of execution of the planter band seeding that will improve the quality of tillage and direct band seeding in stubble and turf, increasing the lifetime of the l-shaped blades and lower energy milling.

Moreover, they are mounted so that each of the radial projections leading coupling 15 is located in a respective radial slot of the intermediate sleeve 17 and between the side opposite to the direction of rotation of the working body established compression springs 18. Driven half coupling 16 is connected to the intermediate sleeve 17 stoppers 19, mounted in radial holes slave coupling halves 16 and diametrically located recesses on the outer surface of the intermediate sleeve 17. The pressure of the stoppers 19 on the intermediate sleeve 17 determines the amount of load on the l-shaped knives 13, in which the stopper 19 extend from diametrically spaced recesses, and driven half coupling 16 begins to rotate relative to the leading coupling 15 with the intermediate sleeve 17, and the reg is associated compression springs 20. The intermediate sleeve 17 is installed at the leading coupling 15 on the roller 21 and driven half coupling 16 on bearings 22, which allows them free to rotate relative to each other.
The band seeder sowing works in the following way. If the machine moves band seeding l-shaped blades 13 mounted on the disks 12 of the working body 11 of the milling section 6, milled band soil monolith turf. In the treated layer of soil from the hopper for seeds 3 through seeding apparatus 4 according to the VAS deferens 5 and amanpreetalam 10 serves seeds. Next, the soil in the treated strip is sealed by the packer rollers 7.
Rotation from the leading coupling 15, mounted on the output shaft of the milling section 6, slave to the coupling 16, on which the disks 12 of the working body 11 with G-shaped knives 13, is transmitted through a spring-loaded stoppers 19 through the intermediate sleeve 17. The magnitude of the transmitted torque depends on the magnitude of pressure on the brakes 19 compression spring 20. The intermediate sleeve 17 connected to the lead 15 through the coupling of the compression spring 18 is mounted between the radial protrusions of the leading coupling 15 and the walls of the radial slots of the intermediate sleeve 17 on the side opposite the direction of rotation of the working body, smoothes the shock load on the l-shaped knives 13, with powoduje the entry process of a knife into the soil.
At the meeting of the G-shaped knife 13 with an obstacle compression springs 18 are compressed prior to selecting the gaps between the coils of the springs, which is the beginning of the release spring-loaded stoppers 19 slave coupling 16 from the respective diametrically located recesses intermediate sleeve 17, and driven half coupling 16 begins to rotate relative to the leading coupling 15. After contact with an obstacle end, the stoppers 19 slave coupling 16 under the action of springs 20 are diametrically located recesses intermediate sleeve 16, the compression spring 18 between the intermediate sleeve 17 and the leading coupling 15 will be straightened, and the milling process of the soil will be resumed.
