A hydroseeder comprises a tank with a filler neck and an outlet fitting, arranged on a frame, a stopcock, a pipeline, coulters and a system of self-intake a sowing mixture, which includes a container for germinated seeds with a calibrated pipeline, connected with the coulters of the hydroseeder, and the seed container has openings in the bottom for continuous sucking of water that are smaller than the sizes of the seeds, and number thereof provides the inflow of water into the seed container in such a manner as to allow it to be constantly filled with water, the place of arranging sucking openings provides bubbling of the water-seed mixture in the area of entry thereof into the calibrated pipeline, and seed container itself is installed in an additional working container for water, which is arranged on the frame of the hydroseeder below the tank, is connected therewith by the pipeline through a shut-off valve and provided with a system of maintaining the constant water level, which is made as a float-valve mechanism. The float-valve mechanism is provided with a controlling unit of changes in the upper float position. The controlling unit consists of a rod placed in the tube, at the other end of which a float is fixed in such a manner as to allow moving the rod in the tube and fixing thereof, and in the water-seed container a scale is attached laterally, according to which the required water level is established. The provision of the float mechanism with the controlling unit of filling the water-seed containers with water allows adjusting the sowing rate. |
