Greenhouse spraying system with a mist, without fan

摘要

Spraying system for greenhouses acting without ventilator and composed of an air-compressor (fig.1(1)) situated outside the greenhouse to supply with air the spraying units placed inside. The nebulization units (fig.2) reduce plant medicines to fine dopplets by means of compressed air and special injectors (nozzles) (4). The quality of spraying is obtained by adjusting of the nut (fig.3(2)) of the injector (fig.3) and the continual stirring of the medicine, during spaying, by air supply to the bottom (6). The advantage of said invention is that it fights successfully any plant desease by means of the uniform nebulization into the closed space of the greenhouse, it protects helth since the human presence during spraying is excluded, it sprays any kind of medicines of any density, and it works with lesser quantity of medicine (3l per 1,000m2) reducing thus the consumption thereof for improved environmental protection.
