Fan-less system for spraying a greenhouse, consisting of an air compressor (Fig. 1.1) outside the greenhouse from which air passes to the atomiser units inside. The atomiser units (Fig. 2) atomise (convert to tiny droplets) the agrochemical contained in a conical vessel 2 by means of the compressed air and special nozzles (beaks) 4. Qualitative spraying is carried out by adjusting the adjustment nut (Fig. 3.2) of the nozzle (Fig. 3) and by continually stirring the agrochemical in the container (Fig. 2.2) during spraying by blowing air through the bottom 6 of its base. The advantages of this invention are that it successfully combats all plant diseases by ensuring uniform spraying within the closed space of the greenhouse, it does not require human intervention (so protecting human health), it sprays agrochemicals of any type and density, and it achieves savings in the consumption of agrochemicals because it operates with a smaller quantity (approximately 3 litres per 1000 square metres)and so too has less impact on the environment. |
