Description

[Detailed Description of the Invention] The present invention relates to an improvement of a silo for storing feed grass and the like.

Traditional silos are used to pre-dry grass etc. cut at the appropriate time to an appropriate moisture content, add the necessary additives, pressurize, seal, and take out at the required time to use as feed. In order to do this, a sealed type, for example, a plastic sheet placed in the soil and covered all around, or a large vertical type with a diameter of several meters and a height of more than 10 meters are used. I was able to do it.

With these conventional methods, management and work efficiency such as grass cutting, pre-drying, and rain protection are impaired, and losses during storage are reduced.
Effective use of silo volume, reduced pasture weight, reduced nutritional value or solid matter, and sometimes harmed livestock due to decomposition.

In view of the above-mentioned drawbacks of conventional silos, the present invention aims to efficiently utilize high-quality silage in silos and improve workability during pasture storage.

Next, an outline of the present invention will be explained.

Make the silo a sealable structure.

A take-out port is provided at the bottom of the silo, and a grass charging port is provided at the top.

The upper part is equipped with a sealable lid, and a mechanism for detecting the gas composition inside the silo is provided at an appropriate location, as well as a mechanism for discharging the gas inside the silo and reducing the pressure if necessary.

An inert gas injection pipe is provided at a suitable location in the lower part of the inside of the silo so as to be in contact with the entire inner peripheral surface, allowing the inert gas introduced from the outside to pass through the silage in a dispersed manner and reach the upper part. Depending on the detection result of the upper gas composition, internal pressure is reduced or inert gas is introduced.

Next, one embodiment of the present invention will be described.

Figure 1 shows a side sectional view of an above ground tank type silo.

The one shown is a large one with a diameter of 3 meters and a height of 10 meters.

It can store approximately 50 tons of grass.

Appropriately dried grass (usually 70-75% moisture content) is placed in the bottom cover 8 of the silo bottom inclined part 5 and outlet pipe part 6, excluding the top cover 3.
Fill it from the inside to the top.

The grass can be dried to a moisture content of 40-50%.

The inert gas piping 7 arranged on the inner surface of the lower part of the silo is installed all around the lower part of the silo. A protective plate 17 is used to protect the piping and pipe hole clogging.

An inert gas 20 is injected between the grass in the interior 2 of the silo 1 through the valve 23 and the pipes 22 and 7 at the same time as or after the grass is introduced.

Nitrogen or carbon dioxide gas is used as the inert gas and replaced with the oxygen in the silo to prevent the oxidation of grass and the production of malignant compounds, such as the activity of butyric acid bacteria.

After feeding the grass, the upper lid 3 is sealed, and the interior 2 of the silo 1 is depressurized by a vacuum pump 12 driven by a motor 15 through a small lid 4 provided at an appropriate location on the edge of the upper lid. Exhaust air 14 through valve 13 so that
do.

At this time, the detection mechanism 9 detects the gas pressure and gas composition, detects the gas state inside the silo 2, and maintains the gas composition inside the silo 2 at a predetermined level by adjusting the exhaust 14 and the injection of inert gas. This improves pasture storage.

The sap produced by the grass is discharged from the pipe 16.

The grass is taken out at the required time by opening the lower cover 8.

The entire silo is supported by legs 15.

The silo of this invention not only reduces the pressure inside the silo, but also
Changes in the internal gas can be detected and adjusted, and a predetermined gas composition can be maintained by injecting inert gas.

Even if the pasture is not sufficiently dried or is damaged by rain or snow after drying, losses due to this can be reduced.

It is possible to extremely reduce deterioration and deterioration of grass, weight loss of solid content, decomposition of nutrients, etc.

As already mentioned, the sealable silo of the present invention can reduce the internal pressure and maintain a predetermined gas composition, and in response to the signal obtained by the gas detection mechanism, inert gas can be injected under pressure. , it is possible to prevent deterioration and deterioration of grass.

Improves the effective use of pasture and the efficiency of silos, maintains the quality of pasture, and makes work easier.

It is also suitable for storing grains other than grass.
