Description

The invention relates to agriculture and can be used for introducing liquid biological preservatives in a finely divided state into a silage directly when mowing forage crops and in stationary conditions.

A device for introducing preservatives [1], containing a container, a shut-off valve, a filter, a pipeline, sprayers, a diametrical fan with a width equal to the width of the selected roll. In the device, the supply of working fluid is carried out through ejection nozzles installed in the outlet duct of the fan, made in the form of a diffuser, at a distance from each other, which ensures overlapping of the spray cones on the surface of the rolls.

The disadvantage of this device is the large loss of an expensive preservative applied in the form of aerosols directly to the roller coming from the header to the chopper of the forage harvester and, as a result, the inability to ensure its introduction in minimal doses.

A device for introducing preservatives [2], containing a spray, a preservative flow regulator, a container, pipelines and valves, is known. In this device, the introduction of preservatives is carried out by a centrifugal atomizer with restrictive covers installed on the sides, on the drive shaft of which an impeller is rigidly fixed above the disk, creating an axial air flow directed downward.

The disadvantage of this device is the large loss of an expensive preservative applied in the form of aerosols directly to the roller coming from the header to the chopper of the forage harvester and, as a result, the inability to ensure its introduction in minimal doses.

The purpose of the invention is to reduce losses and ensure the introduction into the silo mass of biological preservatives in small doses.

This goal is achieved in that the device for making small doses of liquid biological preservatives contains a nebulizer, preservative flow regulator, capacity, pipelines. The device includes a compressor, and the atomizer, which is both a disintegrator and nozzle, contains a housing, on the outside of which there is a mounting bracket, a vertical nozzle for supplying biological preservatives by gravity from the tank and a side nozzle for compressed air, a back cover and a nozzle cover, and inside - an impeller with a shaft and a separator.

In FIG. 1 shows a schematic diagram of a device for introducing small doses of liquid biological preservatives; in FIG. 2 is a side view in section of a nozzle-disintegrator; in FIG. 3 is a section AA in FIG. 2.

A device for introducing small doses of liquid biological preservatives contains: a container for a biological preservative 1 with an outlet valve 2, a nozzle-disintegrator 3, a compressor 4 with a valve 5, a pipe 6 for supplying a preservative, a pipe 7 for supplying compressed air. The main working element of the device for introducing small doses of liquid biological preservatives is the nozzle-disintegrator 3, which ensures the disintegration of the liquid preservative and the supply of its finely divided drops directly into the silo of the forage harvester. The nozzle-disintegrator 3 has a housing 8 with a vertical nozzle 9 for supplying preservative by gravity, a side nozzle 10 for supplying compressed air and an arm 11 for mounting the nozzle-disintegrator 3 on the combine silo. The housing 8 of the nozzle-disintegrator 3 is equipped with a rear cover 12 (external shaft support) and a nozzle cover 13. Inside the nozzle-disintegrator 3 there are an impeller 14 (8 vane wheel) with a shaft 15 and a separator 16 (internal support of the impeller shaft).

The housing 8 of the nozzle-disintegrator 3, the vertical nozzle 9 for supplying the preservative by gravity, the side nozzle 10 for supplying compressed air, the bracket 11 for attaching the nozzle-disintegrator to the combine silo and the nozzle cover 13 are made of steel. The back cover 12 (external shaft support) and the separator 16 (internal impeller shaft support) are made of fluoroplastic. Krylchatka 14 (8 impeller wheel) with a shaft 15 - from duralumin.

A device for making small doses of liquid biological preservatives works as follows. The compressor of the brand, for example, A29.01 supplies compressed air through the side fitting of 10-8 mm nozzle-disintegrator 3 to the impeller 14 (impeller) and spins it. At the same time, through a vertical nozzle 9, which also has 0 8 mm, a preservative is fed by gravity from the tank 1 to the impeller 14, where it is disintegrated to a finely dispersed state and, in this form, through the separator 16 and the nozzle cover 13, the drug is introduced into the air silo line.

The productivity of the developed equipment was determined at the hospital as follows. 1500 ml water was poured into a container with a 1 measuring cup. The crane 2 was opened, installed in the lower part of the refueling tank 1, then the compressor 4 and the stopwatch were turned on. The fluid from the tank 1, located above the nozzle-disintegrator 3, came through a vertical nozzle 9 into the body 8 of the nozzle-disintegrator 3 by gravity. In this case, the air, the supply of which from the compressor is regulated by a valve 5, was supplied through the nozzle 10 to the nozzle-disintegrator 3 and untwisted the impeller 14 to 2000 rpm, which contributed to the transformation of the incoming liquid into a finely dispersed state and the flow through the separator 16 to the nozzle 13. Opening fully or half of the tap 2 of the container 1 regulated the consumption of preservative. The maximum flow rate of the sprayed liquid reached 500 ml / min.

The developed device based on a metering pump operating from compressed air allows biological preservatives in the form of finely dispersed sprayed liquid in an amount of 100 to 500 ml / min to be added to the green mass, intended for silage, especially on a forage harvester. Using the proposed device eliminates the use of core (barrel), membrane, etc. pumps for supplying preservatives to the silage mass, powered by electric motors adapted to 12 or 24 V electric equipment of modern combines. Small doses of drugs introduced per ton of silage raw materials do not require large containers and frequent stops of the combine for refueling with a preservative.

A device for introducing small doses of liquid biological preservatives can also be used in a hospital, for example, when preservatives are added to flattened grain of high humidity, which are stored in plastic sleeves.

The proposed device allows to reduce the loss of preservative due to the thorough mixing of its finely dispersed particles with particles of shredded green mass moving along the silo and is simple and low price.
