DEVICE FOR APPLYING CHEMICALS WITH IRRIGATION WATER ON DISCRETE IRRIGATION SYSTEMS Russian patent published in 2022 - IPC A01C23/04 A01G25/02 

FIELD: agricultural mechanization.

SUBSTANCE: invention relates to the field of agricultural mechanization, in particular to the multipurpose use of irrigation systems for discrete irrigation for the introduction of solutions of chemicals into the soil with irrigation water. The device contains an irrigation water accumulator (1) with a siphon (2) operating in an automatic mode, a feeding tube (3) with a tap (4), an open container for solutions of chemicals (5) and a closed measuring container (6) installed below the container for solutions. The irrigation water accumulator (1) is equipped with an air cap (7) installed by means of a rod (8) and a retainer (9) in the accumulator and communicated with a closed measuring container (6) by an air channel (10) with an elbow (11) above the open container for solutions chemicalization means. An open container for chemicals (5) is installed above the level of the irrigation water accumulator (1). A closed measuring container (6) is communicated with an open container for solutions of chemicalization means (5) by a hydraulic channel (12) with an elbow (13) greater than the distance between the air cap (7) and the upper water level in the reservoir. One end (14) of the channel is located at the bottom of the container for chemicalization means (5), and the other (15) at the lid of a closed measuring container (6) communicated with the irrigation water accumulator (1) by a hydraulic channel (16) with two elbows (17 and eighteen). The lower elbow (17) is located below the air cap (7), and the upper (18) is located above the level of the open container for solutions of chemicals (5). One end (19) of the channel is passed through the bottom with the possibility of changing its level, and the other end (20) is located in the area of ​​the stream of water coming from the feed tube (3) to the irrigation water accumulator (1).

EFFECT: simplified design and increased efficiency of the device are provided.
