Claims (3)

1. Combined furrow-cultivating and sowing unit, mainly for the simultaneous cutting of small sown irrigation furrows and sowing crops of continuous sowing (grain, perennial grasses, etc.) during surface irrigation along flooded flowing furrows, containing a tractor connected to it with a frame which is equipped with support wheels, a sowing box equipped with sowing machines, connected seed tubes with openers, furrowers, each of which is mounted on the front beam of the frame and in It includes working bodies made in the form of furrow-forming paws with cutting edges, mounted on its longitudinal beam with the possibility of vertical movement, a trapezoidal sealing roller with ring flanges and mechanisms for setting the working bodies in the transport position, characterized in that the furrow-forming paws are mounted on vertical racks, and racks on the longitudinal beam trace in trace, while the front furrow-forming paws are set to a depth

(H + a), and the rear ones to a depth of (H + a), where H is the depth of the furrow; a - seed embedding depth, while the front furrow-forming paw is lancet, flat-cutting and equipped with cylindrical left and right dumps corresponding to the groove profile, and the rear furrow-forming paw is combined in two levels, the lower level paw being lancet, flat-cutting, and the upper level paw is lancet flat-cutting and equipped with cylindrical left and right dumps corresponding to the groove profile and installed with an angle exceeding the angle of crushing of the sown soil (more 30), each furrow-forming device is spring-loaded relative to the frame with the possibility of vertical movement of lancet flat-cutting legs fixed on the longitudinal beams independently of each other, while the extreme furrow-forming machines are installed along the track width of the supporting-drive wheels and are equipped with limiters for moving their longitudinal beams to the furrow depth not more than N, and the trapezoidal compacting rollers are mounted on a cylinder mounted on the frame of the support and drive wheels and can move depending on inter-furrow distance, wherein the compacting roller is installed in front of the sowing device, and the sowing device is equipped with double-disc coulters, which are spring-loaded relative to the frame with the possibility of vertical movement independently of each other. 2. The combined unit according to claim 1, characterized in that each limiter to move the longitudinal beams of the extreme furrowers is made, for example, in the form of a chain. 3. The combined unit according to claim 1, characterized in that each limiter to move the longitudinal beams of the extreme furrowers is made, for example, in the form of a hydraulic cylinder.
