摘要：
Device for introducing liquid manure into the irrigation water relates to agriculture, in particular to devices for making agrochemicals with irrigation water and may be used for irrigation and watering machines, different irrigation installations and pressure irrigation pipes for liquid fertilizer, herbicides and other working compositions pesticides in irrigation water.The purpose of the utility model is to simplify the construction of the device, increasing its reliability and reducing costs of operation by creating a compact pump unit and metering its return valves.This object is achieved in that the device for introducing liquid manure into the irrigation water, comprising a tank for liquid manure, pipes, hydraulic communication channels, a hydraulic motor with a piston kinematically joined via a rod on the one hand with the control valve through a spring-loaded switch, and on the other hand with metering pump with working cavities and check valves, check valves are made in one block in the form of a housing with radial inlet and outlet passages and with end caps working channels, n When in use, the input channel is connected with a container for liquid fertilizer, the output channel is connected to the feed line, and the end working channels communicated with the working cavities metering pump, in addition, the housing of check valves is hollow with small and large diameters symmetrically inlet axis, and the cap with the end working channels are provided with small and large elastic washers contacting, respectively, with small and large diameters of the hollow body, the end working channels communicated with the cavities mezhshaybovymi small and large rib washers cavity between two small washers communicates with the inlet channel and the cavity on large washers are interconnected and the outlet.The use of utility model in agriculture will increase the reliability of the systems of irrigation of crops and productivity of agricultural production. 5 yl.Устройств
