Description

[Detailed Description of the Invention] The present invention relates to a bag silo for adjusting silage. More specifically, the present invention relates to a bag silo that is equipped with a gas venting section that can vent gas generated during the initial stage of silage preparation and prevents air from flowing back into the silo after the gas production has subsided.

Silage conditioning silos used to be constructed from concrete structures.
This concrete silo has the disadvantage that it is not only expensive to manufacture, but also requires considerable manpower to adjust the silage using this silo.

As a technology to eliminate the above drawbacks,
The methods described in Japanese Utility Model Publication No. 29408 and Japanese Utility Model Publication No. 16778-1987 were proposed. The method described in Japanese Patent Publication No. 45-29408 adopts a method in which silage is not adjusted in a concrete silo but in a prefabricated silo, and the silage material is stored in a special synthetic resin film bag. Adopt a method of adjustment.
The method described in Japanese Utility Model Publication No. 47-16778 relates to the structure of a simple, easy-to-assemble silo that does not require the installation of a fixed silo.

Recently, along with advances in agricultural machinery, the method of using a special synthetic resin film bag described in the above-mentioned Japanese Patent Publication No. 45-29408 as a bag silo without combining it with a prefabricated silo has been adopted. Summer.

That is, the grass in the meadow is cut with a reaper, and the cut grass is dried to some extent (pre-drying). After pre-drying, the grass is rolled up into a roller baler with a diameter of 50 to 250 cm and a length of 50 to 300 cm using a grass collector connected to a tractor. In this method, the raw material is placed in a synthetic resin film bag (bag silo) large enough to accommodate a roller baler, the bag is tightly sealed to prevent air from entering, and fermented under anaerobic conditions to produce silage.

According to this method, fermentation of the pre-dried grass begins two to three days after it is placed in the bag silo, and it can be fed after about two weeks. However, there was a problem in that during the fermentation process, the silo filled with gas and the gas pressure caused the bag silo to burst. If the back silo bursts, the silage will be wasted, which is undesirable.

Under such circumstances, the inventors of the present invention have conducted extensive research with the aim of providing a bag silo for silage adjustment that can easily remove the gas generated when fermenting pre-dried grass stored in the bag silo. As a result, the present invention was completed.

The gist of the present invention is, in a bag silo 1 for silage adjustment made of a soft impermeable or poorly permeable synthetic resin film 2, an opening 3 for stuffing grass etc. is provided at one end of the cylindrical bag. A multi-hole part 5 with a large number of small holes 4 drilled in a small area is formed at a location where a cylindrical wall surface is formed when the bag silo is made. Overlapping the covering film 6 with a wider area,
The synthetic resin film 2 constituting the cylindrical bag and the outer periphery of this covering film 6 are bonded at arbitrary intervals with non-adhesive parts 7.
This bag silo for silage adjustment is characterized in that it is equipped with a gas venting part 9 which is bonded with a part left in place.

In the present invention, a soft impermeable or air-resistant synthetic resin film refers to a synthetic resin film that is flexible and is air-impermeable or air-resistant. Specifically, thickness 0.05
~0.3mm polyethylene film, polypropylene film, flexible compounded polyvinyl chloride film, ethylene-vinyl acetate copolymer film,
Examples include polyvinylidene chloride film, which may be a single layer film or a laminated film in which different films are laminated. These films may be transparent or colored.

Hereinafter, the bag silo for silage adjustment according to the present invention will be described in detail based on the drawings, but the present invention is not limited to the following examples unless it exceeds the gist thereof.

The bag silo for silage adjustment according to the present invention accommodates roller balers of various sizes,
It is fermented under anaerobic conditions, turned into silage, and stored without deterioration.

As shown in FIG. 1, the bag silo 1 for silage adjustment is a cylindrical bag, and an opening for stuffing grass, etc. is provided at one end in the length direction. The cylindrical bag is
A structure in which a single film is folded and stacked, and an L-shaped adhesive part is formed at the end.A single film is folded and stacked, the folded part becomes the bottom, and adhesive parts are formed at both ends. Others have a seamless cylindrical structure with one longitudinal end glued together, others have a cement bag-like structure, and others have an opening at one longitudinal end for stuffing grass, etc. Any structure may be used.

The size of the bag silo can be selected from a range of 80 to 500 cm in length and 50 to 300 cm in opening diameter.

The bag silo for silage adjustment according to the present invention includes a gas venting section 9. This gas release 9
After storing the pre-dried grass in a bag silage for silage adjustment, the opening 3 is tightly sealed with an opening closing string 10 to allow the gas generated when fermenting the grass etc. under anaerobic conditions to escape. After the function is fulfilled and the gas is released, the moisture accompanying the fermentation gas accumulates in the narrow gap formed between the film 2 and the covering film 6 that make up the cylindrical bag, and air escapes from the outside of the bag silo. It functions to suppress the inflow.

The gas vent 9 forms a multi-hole part 5 in which a large number of small holes 4 are bored in the synthetic resin film 2 constituting the cylindrical bag. A synthetic resin film 2 constituting a cylindrical bag and the outer periphery of the covering film 6 are bonded to each other, leaving a non-bonded part 7 at an arbitrary interval.

The small holes 4 are preferably selected from a diameter range of 1 to 50 mm, and the number of small holes 4 constituting the multi-hole portion 5 is preferably two or more. A large number of small holes are drilled within a small area. The size of the covering film 6 can be selected from a range of 30 to 200 mm in length.

The covering film 6 overlaid on the multi-hole portion 5 is
The area is larger than the area of , and the holes are stacked so as to cover all the holes of the multi-hole portion 5. The synthetic resin film 2 and the covering film 6 are bonded together by forming bonded portions 8 along the outer periphery of the covering film 6, leaving non-bonded portions 7 at arbitrary intervals. It is preferable that the ratio of the non-bonded part 7 to the bonded part 8 is larger than the former.

The gas vent 9 is installed at a location where a cylindrical wall is formed when silage materials such as grass are stored (a location that is not the bottom wall and is not on the opening side).
shall be. The number of gas vents 9 provided may be several depending on the size of the bag silo.

The covering film 6 for forming the gas vent 9 is of the same type as the synthetic resin film constituting the bag silo,
The thickness is preferably the same or slightly thinner.

The following procedure may be used to adjust silage using the bag silo for silage adjustment according to the present invention.

1 Harvest grass and other raw materials for silage in a meadow using a reaping machine or other means and dry it to some extent.

2. The pre-dried silage raw material is collected by a grass collector connected to a tractor, rolled up into a roll, and made into a roller baler with a size of several kg to 700 kg each.

3 This roller baler is stored in the bag silo from the opening 3 for stuffing grass etc. of the bag silage for silage adjustment according to the present invention, the opening is narrowed, and the opening closing string 1 is tied as shown in FIG.
Tie with zero and seal.

4 In this state, leave it in the pasture near a stable, cow shed, etc., or in a house to ferment, and the fermentation gas filling the bag silo is discharged from the gas vent 9 (Figure 3 A).

The gap through which the gas passes through the gas vent 9 is narrowed (FIG. 3B), and moisture accompanying the fermentation gas accumulates in this narrow gap, thereby suppressing the inflow of air from outside the bag silo.
