DEVICE FOR APPLYING CHEMICALS WITH IRRIGATION WATER ON DISCRETE IRRIGATION SYSTEMS Russian patent published in 2021 - IPC A01C23/04 A01G25/02 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to the field of agricultural mechanization, in particular to the multi-purpose use of discrete irrigation systems for introducing solutions of chemical agents into the soil with irrigation water. The device contains a storage tank of irrigation water (1) with a siphon (2) operating in automatic mode, a feeding tube (3) with a tap (4), a container for solutions of chemicals (5) and a measuring container (6). The container (5) is made closed with a stepped bottom and a lock (9) and is installed above the level of the irrigation water storage (1), it is connected to the zone of the water jet coming from the feeding tube (3) to the irrigation water storage (1) through a drain tube (10) with a tap (11), the inlet (12) of which is located at the level of the lower bottom zone (8), and the outlet is at the level below the upper bottom (7). The container (5) is equipped with an open measuring container (6) with an expander (14) and a guide rod (15), installed on a sliding fit in the lock (9). The cavity of the measuring container by means of an expander (14) and a flexible tube (16) with a knee (17) located above the container of solutions of chemicals (5) is communicated with the area below the outlet level (13) of the drain tube (10) with a tap (11).

EFFECT: provides simplification of the design and an increase in the efficiency of the device.
