Description

[Detailed description of the invention] The present invention allows livestock feed, such as grass, to be easily dried to a predetermined moisture content using outside air that is sucked and circulated from the periphery to the center, or for a long period of time without causing decomposition and deterioration. The present invention relates to a simple storage/drying device that can be stored for a long period of time.

Conventionally, livestock feed, such as pasture grass, must be dried to an appropriate moisture content after harvest, otherwise it will rot and deteriorate, making it unsuitable for livestock feed.

Therefore, in the past, a large, independent grass drying room was built and used to dry grass.

Therefore, drying work using a drying room as described above is either very expensive to construct and is not suitable for the general public, or even when a small amount of grass is required, it is wasteful to distribute drying air throughout the drying room. In addition to the economic disadvantage of consuming fuel and electricity and increasing drying costs, there is also the disadvantage that storage management work to store dried grass in a mutually effective state for a long period of time cannot be carried out efficiently. This is something that was strongly desired to be improved.

In view of the above, the present invention has a double cylinder whose periphery is sealed, the upper part of which is open, one of which is formed into a corrugated cross-section, and the other is arranged in a cylindrical shape so as to be in contact with a protruding part of the cross-section. By that,
A plurality of sets of ventilation passages are provided between the outer cylinder and the inner cylinder, and the inner cylinder facing the ventilation passages has many ventilation holes, and the center of the double cylinder has a large number of air intakes on the circumference. A suction cylinder with an open mouth is opened to the outside of the double cylinder, a suction exhaust fan is housed in the suction cylinder, and the grass filled and stored in the inner cylinder is passed through the air passage 2 vent and the intake port. It is possible to quickly dry the product to a predetermined moisture content by attracting and circulating outside air from the outer periphery to the center, and it is possible to quickly dry the product to the specified moisture content.The provision of multiple ventilation channels makes it possible to adjust the amount of outside air ventilation, which can be done with one device. The purpose of the present invention is to provide a simple storage and drying device that can easily store pasture grass, and the configuration of the device according to the present invention will be described below with reference to preferred embodiments shown in the accompanying drawings. do.

Reference numeral 1 denotes an outer cylinder having an open upper end and a sealed periphery, and an inner cylinder 2 having an open upper end is accommodated within the outer cylinder 1.

When the inner cylinder 2 is formed into a wave-shaped cross section as in the first embodiment shown in FIG. 2 among the outer cylinder 1 and the inner cylinder 2,
A plurality of set-shaped ventilation passages 3 are provided between the outer cylinder 1 and the inner cylinder 2 so as to be in contact with the protrusion having a wave-shaped cross section, and the ventilation passages 3 are
A large number of vent holes 4 are opened in the wall surface of the inner cylinder 2 facing the air passage 3 and the inside of the inner cylinder 2 to communicate with each other.

Further, when the outer cylinder 1 has a corrugated cross section as in the second embodiment shown in FIG. A large number of set-shaped ventilation passages 3 are provided, and a large number of ventilation holes 4 are opened in the wall surface of the inner cylinder 2 facing the ventilation passages 3.

At the center of the double cylinder formed as described above, an intake cylinder 5 with a large number of intake ports 6 opened on the circumferential surface is provided upright, and the discharge side of the intake cylinder 5 is directed to the outside of the outer cylinder 1. with an extending opening;
Moreover, a suction exhaust fan 7 is housed inside the intake cylinder 5.

Reference numeral 8 denotes a roof for covering the open upper ends of the outer cylinder 1 and the inner cylinder 2, and the roof 8 is removably attached by a suitable mounting rod 9.

It is desirable that the aforementioned outer cylinder 1 and inner cylinder 2 be made of a material that is highly corrosion resistant and lightweight.

In this embodiment, the outer cylinder 1 and the inner cylinder 2 are made of a plate material having aluminum plates 11° 11 attached to the inner and outer surfaces of a synthetic resin plate 10 as shown in FIG. However, it is of course possible to use other materials.

Next, the operation of the present invention will be explained using the first method shown in FIGS. 1 and 2.
An example will be explained.

Now, the roof 8 is removed and the inner cylinder 2 is completely filled with harvested grass to be dried, and then the roof 8 is placed again.

Next, when the suction/exhaust fan 7 is operated, the suction action of the suction/exhaust fan 7 causes outside air to be sucked and distributed directly into the inner cylinder 2 from the open top side through the grass, and outside air other than the above is provided in the double cylinder. The grass is inhaled into the suction cylinder 5 through a plurality of air passages 4 filled with grass through the air passages 4, through a concentrated circulation process leading to the intake port 6 of the flame, and then directed outward from the discharge side. is discharged.

Therefore, the amount of outside air that circulates between the pastures increases gradually from the outer periphery toward the center.
Due to the suction and circulation effect of outside air, not only the filled grass but also the grass in the center, which is difficult to dry, is evenly accelerated and dried to a predetermined moisture content, so it can be taken out as appropriate and given to livestock.

In addition, if you want to store grass dried using the above device for a long period of time, by circulating a smaller amount of outside air than the amount of ventilation used during the drying process, the grass can be stored for a long time without rotting or deteriorating. stored over time.

In short, the present invention consists of opening the upper part of a double cylinder with a sealed periphery, forming one side with a corrugated cross section, and arranging the other cylinder in a cylindrical shape so as to make contact with the protruding part of the corrugated cross section. A plurality of sets of air passages 3 are provided between the outer cylinder 1 and the inner cylinder 2, and at the center of the inner cylinder 2 facing the air passages 3, there is an intake cylinder 5 with a large number of intake ports 6 opened on the circumferential surface. is opened to the outside of the double cylinder,
Since a simple storage and drying device was constructed by storing a suction exhaust fan in this suction cylinder, a storage and drying device that can be easily installed anywhere can be economically constructed to perform the storage and drying functions of grass as appropriate. Rather than pretending that it is possible, outside air is formed between the outer cylinder 1 and the inner cylinder 2 and is uniformly sucked into the outer periphery through an independent ventilation path 3. The grass filled in the inner cylinder 2 is concentratedly circulated from the surrounding area to the central intake pipe 6, and at the same time, from the open side of the upper end of the inner cylinder 2 to the central intake port 6, the outside air sucked and circulated is The amount of airflow gradually increases as it moves toward the suction pipe 5, and the amount is increased to the grass in the center, which is difficult to dry, and the drying air concentratedly distributed in the center can dry the grass uniformly.

This civil engineering device has many ventilation channels, so by simply adjusting the flow rate of outside air, dried grass can be stored for a long time without rotting or deteriorating using one device. Moreover, even a small amount of grass can be quickly and easily stored and dried.
