A hydraulic sowing unit includes a cistern with a driving mixer disposed therein and a discharge spout with a lock-up device, a regulating system, the composition of which comprises a sensor of the level of liquid as a container mounted immovably, connected in the lower part to the cistern by a piping, and a float arranged therein, a regulating device including a cylinder provided with an inlet and an outlet with a piston component with a spring-loaded rod, connected to the float by a rope, arranged therein, a distributing chamber, connected with the outlet in the cylinder by a spout and provided by outlet spouts. The outlet in the cylinder is made as a flat slot in the middle part of the cylinder across length thereof, and the piston component has an opening in perpendicular to the axis of the piston component as a wedge with an extension in the lower part extended along the piston component. The cylinder in cross-section is shaped as a rectangular, and the piston component is made as a plate of a similar shape which is self-pressed to the side of the cylinder with an output slot-like opening. |
