Device for proportional application of products by spraying (Machine-translation by Google Translate, not legally binding)

Device for proportional application of products by spraying, for application in the treatment of fruits, vegetables and the like, and in which the product to be sprayed is stored in a tank (5) with agitator (6) for homogenization of said product to spraying, which is applied to a dosing pump (6) which is connected to a pipe (1) that includes a plurality of ejector nozzles (2) self-cleaning spray product, which are located transversely and above a line of translation (3) of the fruits and vegetables (4) previously selected by size, on which the sprayed product is applied; further comprising the device with a module (15) for detecting the amount of fruit that runs along the line of translation (3), which is connected to a programmable automaton (7) in which, by means of a control panel (20), the amount of product to be applied on the fruit is programmed, and that governs the operation of the dosing pump (6) and of a series of accessories such as valves, filters and hand-reducers, to regulate the amount of product to be applied in function of the working regime programmed in the programmable automaton (7) according to the quantity of fruit (4) that circulates along the line of translation (3); characterized in that the module (15) detecting the quantity of fruit is connected to at least one first sensor (16) arranged azimuthally on the fruit translation line (3) for measuring a first upper point (17) and a second point (18) of the piece of fruit (4); said module (15) being for detecting the quantity of fruit provided with means for calculating the volume of the piece of fruit from the previous measurements and the value of the density of the fruit, value previously stored in said module (15) of detection of the amount of fruit; the device further comprising a line of photocells (19) with background suppression, which is connected to the fruit quantity detection module (15), to indicate the number of pieces of fruit (4) detected, said module also having (15) detection of quantity of fruit with means of calculating the weight of the piece of fruit (4), from the calculated volume, and calculation of the total weight of the fruit that circulates along the line of translation (3), multiplying the weight of the piece calculated by the number of pieces detected; wherein the programmable automaton (7) is configured to calculate and generate pulses at an opening/closing frequency of the nozzles for regulating the amount of product applied according to the amount of pr
