Description

The invention relates to agricultural land reclamation and can be used for irrigation of agricultural crops. A fertilizer feed unit to irrigation pipelines is known, including a suction pipe, a pump unit, a water supply controller, a discharge pipe with an adjustable valve, hydraulically connecting the pressure and suction pipes and an intake pipe of soluble fertilizers, the end of which is inserted into the suction pipe to the point of connection discharge pipe to it 1. The disadvantage of this system is the impossibility of introducing a strictly normalized concentration of both liquid and dry fertilizers with olivnoy water high consumption of materials and energy. The closest technical solution to the invention is a device for supplying fertilizers to irrigation pipes, including a supply pipe, a tank at the outlet of which a metering feeder 2 is located. A disadvantage of the known device is that it does not allow adjusting and accurately metering fertilizer and also does not allow to work at low water flow and head. The purpose of the invention is to increase the efficiency by the normalized dosing of fertilizers with irrigation water, as well as to expand the functionality. The unallocated goal is achieved by the fact that in the fertilizer feeder to irrigation pipelines, including the supply pipe, the tank and the dosing feeder, the latter is made in the form of a movable tank with a drive and a dosing vessel having an empty gate and associated with the tank of a flexible link, the tank drive equipped with a time relay, kinematically associated with the dosing vessel emptying flap. In addition, the supply pipe has a shut-off member kinematically associated with the relay time. FIG. 1 shows the proposed device, a general view; in fig. 2 - hydraulic drive; in fig. 3 - dosing feeder. The device includes a tank 1 for supplying water to the supply pipe 2, equipped with a valve 3, sectional distributors 4 with flow regulator 5 installed on them and humidifiers 6. For metering fertilizer, the system is equipped with a metering feeder 7 including tank 8 with a cover 9 , a set of balls 10 of decreasing size and grids 11, ensuring crushing and sifting of crawler fertilizers, flexibly extended to container 8, dosing vessel 12, equipped with dampers - regulating 13 and emptying 14. Swinging capacity 8, movably closed Heated on support 15, is carried out by raising or lowering the drive shaft 16. The shocks that occur during swinging are perceived by the stop 17, and the capacitance, 8, is reset to its initial state by the spring 18. The shafts 16 and the pushers 19 are moved with the help of the corresponding segment drives 20 and 21 attached to the hydraulic time relay 22. Short-term shut-off of the supply pipe 2 is provided by a shut-off device 23. Water is supplied to time relay 22 through a pulse pipe 24 with valve 25. There is a well 26 with a check valve 27 for receiving and discharging water coming from relay 22. Fixing relay 22 time in a predetermined position and the opening of the valve 14 of the emptying is provided with a pawl 28. The device operates as follows. From the tank 1, water when the valve 3 is open enters the supply pipe 2, and from it through the flow controller 5 to sectional distributors 4 and humidifiers 6. At the same time, water through the impulse pipe 24 with the flow adjusted by valve 25 enters time relay 22. Filling one of the chambers of time relay 22 to a certain level ensures that the pawl 28 is withdrawn from engagement, which acts on the emptying valve 14 filled with fertilizer, the dosing vessel 12 is freed from them. During this time, the time relay 22 rotates by a certain angle depending on the number of working chambers and is fixed in this position by the pawl 28. The emptying valve 14 closes the dosing vessel 12, into which a new portion of fertilizer from the tank 8 enters through the regulating valve 13. When By turning the time relay 22, the segmented actuators 20 and 21 respectively act on the brush 16 and the pusher 19, causing it to swing 8, which strikes the stop 17 and returns to its original position again under the action of the spring 18 and the weight of the brush 16, and closing the closure member 23. Swinging the tank 8 on the support 15 and the translational movements of the balls 10 associated with them create conditions for crushing, intensive movement and sifting of fertilizers through the grids 11. When the closure member 23 is closed, the water coming out of the time relay 22 with a portion of fertilizers, pouring out the check valve 27, opens it and empties the well 26. During the irrigation period, several such cycles are carried out, depending on the total amount of fertilizer used, one-time feed rate, the duration of filling the chambers s hydraulic drive.

irrigation rate and duration of irrigation. When the short supply line 2 is repeated for a short period, a turbulent movement of water is created in it, contributing to the intensive movement of a portion of dissolved fertilizers coming from the well 26 and, consequently, a uniform distribution over the area of the irrigated area. After a given irrigation rate has been supplied, the valve 3 is closed, the water supply to the subsurface irrigation system is stopped.

The device allows to provide strictly dosed application with irrigation water of both liquid and bulk soluble complex fertilizers with minimal expenses for their preparation and application.
