Abstract

The invention relates to agriculture, in particular, to devices for preparing mineral fertilizer solutions and feeding them to irrigation machines. The aim of the invention is to improve the conditions of dissolution of mineral fertilizers and to increase the productivity of a hydroplocator by creating upward and centrifugal flows simultaneously. For this, the supply pipe is divided into two pipes 8 and 9, one of

Mineral fertilizers or chemical meliorants fall asleep in the cavity of the free-flow tank and simultaneously open the valves on the supply pipe. Due to the pressure upflow 13 and the centrifugal (tangential) water currents, the fertilizers are mixed and poured through the upper mesh part of the inner walls of the tank into the cavity between the inner and outer walls of the tank. The valve is then opened in the discharge pipe 10 and the fertilizer mixture is fed into the irrigation network. 1 z.p, f-ly, 2 silt,.

The invention relates to agriculture, in particular to hydropods for irrigation machines, and is intended for preparing solutions of mineral fertilizers and chemical ameliorants and applying them simultaneously with irrigation water.

The purpose of the invention is to improve the conditions for the dissolution of fertilizers and to increase the productivity of the hydraulic feeder by creating both upward and centrifugal flows.

FIG. 1 shows the proposed hydropodcormical, a longitudinal section; FIG. 2 is a section AA in FIG. 1.

The hydraulic chopper contains a free-flow fertilizer tank 1 with internal walls 2, a tapered bottom 3 of the internal cavity of the fertilizer tank, a convex hemispherical mesh partition 4, an upper mesh part 5 of the internal walls of the fertilizer tank, a mesh cover 6 of the internal cavity, 7 fertilizer tank, pipeline with central 8 and tangential 9 pipes, discharge pipe 10. and drain valve 11.

Fertilizers 12 are dissolved by the pressure of water from the supply pipe due to the upstream current 13 of water from the central nozzle 8 and the centrifugal current 14 of water from the tangent 9, the combination of the upstream and tangential water currents eliminates stagnant zones of insoluble fertilizers around the perimeter of the inner walls of the tank , accelerates their dissolution and increases the uniformity of the fertilizer mixture in the irrigation network.

In order to evenly distribute the upward flow of water, the bottom 3 of the inner cavity of the fertilizer tank is made conical. The mesh hemispherical partition 4 prevents the ingestion of fertilizers when they are filled into the central nozzle and clogging it. For

eliminating the ingress of debris and large compacted fertilizers 9, the hydraulic fertilizer, the internal cavity of the fertilizer tank, is covered with a mesh cover 6 from above, and the cavity between the inner and outer walls of the tank - with a solid cover 7,

Hydraulic submachine works as follows.

Into the internal cavity of the tank for

fertilizers uniformly in time load fertilizers or chemical meliorants (feeder-dispenser not shown), open the valves on the supply pipe of pipes 8 and 9, Water under

head with upward 13 and centrifugal 14 Current currents water mixes fertilizers, which dissolve and in the form of stock solution flow over

and

the upper mesh part 5 of the inner walls of the fertilizer tank into the cavity between its inner and outer walls. As the cavity is filled with fertilizer uterine solution more than half the height of the tank, the valve on the discharge pipe 10 is opened. Then, the valves on the inlet and outlet pipe should be adjusted so that there is no overflow through the edge of the tank, i.e. equalize the flow and flow of water. After finishing work with the hydraulic sub-distributor, it is cleaned with clean water, after which the valves on the inlet and outlet pipes are closed, the drain valve 11 is opened, and the tank is emptied of water.

The flow rate of the hydraulic trimmer is consistent with the flow rate of one or several simultaneously working sprinklers. At the same time, the concentration of fertilizers and chemical meliorants in irrigation water should not exceed the permissible values. The optimal condition for the fertilizer to dissolve is to ovoid the flow of water in the pipeline between the central and tangent nozzles or the ratio of their diameters is 2: 1.

 For automatic overflow of dissolved fertilizers into the cavity between the outer and inner walls of the tank, as well as to eliminate lumps of undissolved fertilizers from entering the discharge pipe, and then to the irrigation network, the upper part

the walls of the inner cavity of the fertilizer tank are mesh.
