LIQUID SPRAYING AGRICULTURAL IMPLEMENT Russian patent published in 2025 - IPC A01M7/00 

FIELD: agriculture.

SUBSTANCE: invention relates to an agricultural tool for spraying a liquid product, as well as a method of spraying and a method of controlling such an agricultural tool. Agricultural implement comprises at least one boom having a longitudinal liquid product supply line, and a plurality of nozzles arranged along the boom, a liquid product supply source, at least one pressure control unit including at least one nozzle controller, a speed sensor configured to measure the speed of the agricultural implement. At that, at least one pressure control unit and/or at least one nozzle controller are made with possibility of calculation of time mode data for each corresponding nozzle. Time mode data include at least frequency of spraying (Sfreq) and maximum time of closed state (Tmax). Nozzle controller is configured to control each nozzle from said plurality of corresponding nozzles based on the calculated time mode data of the nozzles, wherein the closed state time should not exceed said maximum closed state time in order to obtain uniform spraying of the liquid product on the surface of the sprayed field. At least one pressure control unit and/or nozzle controller are configured to determine spraying frequency (Sfreq) and/or maximum closed state time (Tmax) when calculating said time mode for each respective nozzle at least partially based on the speed of the agricultural implement. Determination of maximum time of closed condition (Tmax) includes reduction of maximum time of closed condition in accordance with increase of movement speed and increase of maximum time of closed condition in accordance with decrease of movement speed. Method of spraying a field consists in the fact that the above agricultural tool is provided and controlled for spraying the field. Method for controlling an agricultural implement, implemented by a computer, includes steps of obtaining information on the amount of liquid to be sprayed, obtaining information on the speed of the agricultural implement, calculating the nozzles time mode data, including at least, frequency of spraying and maximum time of closed state, in accordance with obtained information on amount of liquid to be sprayed, and speed of movement.

EFFECT: agricultural implement is characterized by quality spraying of liquid product.
