It is suggested a spraying device for field crops processing, which comprises a vehicle-mounted tank for working fluid containing preparation subject to proportioned application into processed surface, working fluid distribution vehicle in the form of a boom having a set of spraying nozzles of a specified productivity, the means of working fluid supply to the spraying nozzles, connected with the said tank and comprising of pumping main and a positive displacement powered pump, and working fluid delivery controlling means. The working fluid delivery controlling means in the spraying device represent power transmission, connected withof the vehicle transmission and a pump shaft to provide fixed conformity of working fluid delivery with the vehicle operating speed for each transmission ratio and performed with a set of transmission ratios to provide operation of the spraying nozzles of a specified productivity in the mode determining preparation application rate into processed surface, a pressure measurement instrument with electrical contact outputs meant for visual and/or audio control of minimum and maximum allowable values of the working fluid operating pressure within the required range being installed in the pumping main. |
