Description

The invention relates to agriculture, in particular to devices for introducing preservatives into the silage mass of fodder plants.

Known equipment for making biological preparations of the design SZNIIMESKH [1]. It consists of a tank with a core submersible pump [2] installed in it, comprising a housing with an inlet and an outlet, a guide apparatus, an electric motor located in the support, and a shaft connected to the electric motor and impellers mounted on the shaft. The electric motor is installed on the upper end of the housing, the shaft support is mounted above the impellers and is made in the form of a stepped sleeve with channels for the pumped liquid, a dividing pipe is installed between the stepped sleeve and the electric motor inside the housing, and the outlet pipe is made lateral. The housing is prefabricated and contains a pipe in the lower part, and a tee connected to the pipe with a lower axial bend in the upper part, the electric motor in the lower part is equipped with a cup, the glass is connected to the upper axial bend of the tee, and the transverse bend of the tee is equipped with a plug with a fitting. The pipe is connected with a tee, and the tee is with a plug and a glass with a pipe-socket connection, the connections being equipped with sealing cuffs. The unit is added with preservatives both in stationary conditions and on forage harvesters. To ensure the operation of this device, use a control panel with power wires, a flow meter with an adjustment valve, nozzle and hoses for supplying fluid.

The disadvantage of this equipment is the complexity of the design of the pump, its low productivity and the inability to ensure mixing of the preservative in the tank, as well as the fact that when pumping solutions of poorly soluble biological preparations like Fercon, the pump becomes clogged.

Known equipment for the introduction of preservatives HVAC 400 (600) [3], intended for the treatment of stalk feed with solutions of biological preservatives in order to preserve their nutritional value during storage. The equipment is made in the form of three nodes, one of which is a frame with a capacity of 400 (600) l, on which a membrane pump and a filter are fixed. The second unit consists of a frame on which a rotameter with a dispenser or a pressure regulator with a pressure gauge is fixed. The third node is the atomizer housing assembly. The equipment is mounted on various forage harvesters, and can also be used in a hospital.

The disadvantage of this equipment is the low productivity of the pump - 0.5-6 l / min and the inability to ensure mixing of the preservative.

The purpose of the invention is to simplify the design and ensure mixing of the preservative.

This goal is achieved in that the installation for introducing preservatives contains a tank, pump, control panel, nozzle and hoses, and outside, under the tank there is a centrifugal pump with an adjustable one-way valve at the inlet and a two-way valve at the outlet with hoses, one of which is through the upper neck lowered into the container, and the other is connected to the nozzle, equipped with interchangeable nozzles with different flow rates.

Figure 1 shows a diagram of equipment for making preservatives, figure 2 is a side view of a nozzle with a nozzle.

Installation for adding preservatives consists of a tank 1 with a pipe 2, under which a high-performance centrifugal pump 3 is installed with a one-way control valve 4 with a valve 5 at the inlet to the pump 3 and a two-way valve 6, equipped with valves 7 and 8, at its output. Two-way valve 6 may be mechanical or electromagnetic. Hoses 9 and 10 are connected to the valve 6, and the hose 9 is inserted through one of the necks 11 into the container 1, and the hose 10 is connected to the nozzle 12, which consists of a nozzle 13 with a union nut 14 with a hole and a nozzle 15. The preservative is controlled by interchangeable nozzles 15 (washers with different inner diameters) installed in the nozzle 12. The pump 3 is operated by means of a control panel 16 with power wires. Capacity 1 for preservatives may have a different volume. In agricultural production, the most common are the capacity of 200 liters. Installation for the introduction of preservatives can be used both on forage harvesters and in stationary conditions.

Installation for making preservatives works as follows. First, a preservative working solution is prepared. Previously, for example, the biological preparation Fercon is diluted in water in a ratio of 1: 3 in a small-capacity tank (10 l) with a breakdown of small lumps. Then 10 or 15 liters of the drug previously diluted in water through the upper neck 11 is poured into a container 1, which is added with water to 200 liters. 4 tons of diluted preservative are added per 1 ton of silage. Then opens the valve 5 of the one-way valve 4, as well as the valve 7 of the two-way valve 6. The pump 3 is turned on by the remote control 16. First, the preservative through the pipe 2 and the hose 9 passes through the upper neck 11 into the container 1, thereby ensuring its active mixing. After a certain period of time sufficient to mix the preparation during operation of the forage harvester, the valve 8 of the two-way valve 6 opens to supply the mixed preservative through the hose 10 to the nozzle 12 and then to the silage mass. Nozzle 12 is installed in the silo of the forage harvester. In the process, with the open valves 7 and 8 of the two-way valve 6, the drug is simultaneously mixed in the tank 1 and fed directly through the nozzle 12 into the silo mass. At the end of the operation, the valves 7 and 8 of the two-way valve 6 and the valve 5 of the one-way valve 4 are closed.

The proposed installation will allow high-quality mixing and introducing into the silage mass of herbs both biological and chemical preservatives. The use of this kind of equipment with preservative flow control due to interchangeable nozzles (washers with different internal diameters) installed in the nozzle will allow you to do without filters and rotameters with dispensers.
