A till-plant outfit has a mounted chisel part with a frame and support wheels at the front end face of which is placed a device for mounting the power carrier vehicle, subsurface cultivation actuators made in form of the share blades with spreaders provided with hollow bars functioning as fertilizer tube; it also has a trailing part made in form of grain drill with a bin for seeds connected to the mounted part and sowing apparatus behind of which is placed a drag chain to level up the surface of sown field. The frame of the mounted part is provided with two pairs of support wheels with different track gage placed at the front and after ends of the frame; the grain drill is also provided with two pairs of support wheels with different track gage at that not aligning with the gages of support wheels placed at the frame of the mounted part. The seed-metering unit of the grain drill is equipped with tangential swirler made in the form of the three screw blades mounted in the bottom part of vertical tube connected to the seed-metering unit which is pneumatically connected to the hollow share blades with spreaders. To provide the sowing process at the frame of the mounted part is placed a high-pressure fan pneumatically connected by double air tube for supply of the seed from the bin to the seed-metering unit, and for ejector supply of the bulk seed to the bin of grain drill. Behind each share blade is placed a separate gravity land leveler made in the form of a section of floating rake with mechanical eccentric governor of the level of its forcing to the soil, and the drag chain is equipped with the inclined ripping teeth for the soil plotting and lateral displacement of plant remainders which are removed from the soil during treatment thereof by drag chain. |
