Description

[Detailed explanation of the idea] This invention relates to the improvement of livestock houses for cold regions.

Conventional livestock barns built in cold regions often have a structure that prevents sunlight from entering the barn, and ventilation is also neglected, so the environmental hygiene is not necessarily good. be.

Particularly for livestock such as pigs and cows, which produce a lot of excrement, the humidity naturally rises abnormally, and some livestock barns are often filled with carbon dioxide and emit strange odors.

Regardless of the warm season, during the bitterly cold season the room temperature drops, so animals are kept in closed barns without ventilation, so it is not uncommon for the humidity to be 100 degrees centigrade.

In such livestock barns, ice forms on the ceiling surface at night, and this ice melts and drips during the day, which can cause the insulation used on the side walls of the ceiling to swell.

Pneumonia and other diseases occur in such livestock barns, resulting in death or significant loss of physical strength, loss of body weight, and decreased milk yield, which is a factor that worsens livestock management.

In view of this situation, the present invention makes maximum use of sunlight, which has immeasurable benefits such as heat energy, sterilization effect, and production of vitamin D, to improve environmental hygiene that is key to raising and fattening livestock. The aim is to provide stable livestock housing and thereby improve the efficiency of livestock management.

Below, an embodiment of the livestock barn according to the present invention will be explained based on the drawings. As shown in Fig. 1, foundations 1 are arranged in a rectangular shape at predetermined positions with constant intervals, and foundations 1 are placed on opposing foundations 1 on both the left and right sides. As shown in Figures 2 to 4, a semicylindrical lattice structure 2 that integrates left and right pillars and arched roof beams.
A large number of lattice structures 2 are erected in parallel, and several places on the upper arch surface and both left and right sides of the large number of lattice structures 2 are connected by longitudinal beams 3.
In addition, place 4 is installed at an appropriate location.

In addition, studs 5 are erected on each foundation 1 at the lower position of the lattice structure 2 at both front and rear ends, and the upper ends thereof are connected to the lattice structure 2, with an appropriate interval between each stud 5 in the vertical direction. The cross beams 6 are constructed and connected to form a steel structure 7 as a whole.

As shown in FIG. 5, block walls 8 are provided at the lower portions of both left and right sides of this steel frame structure 7, and transparent hard plastic plates 9 are airtightly stretched over the roof surface, both front and rear sides, and the upper portions of both left and right sides. It constitutes a building, and in the center of the building there is a first
As shown by the chain lines in the figure, foundations 1' are placed at appropriate intervals, and intermediate columns 10 that are somewhat higher than both sides (portions corresponding to columns) of the lattice structure 2 are placed on each foundation 1'. As shown in FIG. 5, the upper ends of each intermediate column 10 are connected in the front-rear direction by horizontal beams 11, and crosspieces 12 are installed between the horizontal beams 11 and the upper sides of both sides of the lattice structure 2. The mats are erected mid-height at regular intervals in the front-rear direction, and on top of them, as shown in FIG. The inside of the building is partitioned into an upper space 16 and a lower space 17 by being airtightly stretched and supported in a downward slope in a direction that allows water droplets to be discharged, that is, on both sides.

Then, on the upper surface of the transparent mat 15, a light-blocking curtain 18 made by polymerizing a vinyl film mixed with aluminum foil strips at appropriate intervals on the front surface and a white vinyl film on the back surface is arranged downwardly on both sides. Provided so that it can be opened and closed.

This light-shielding curtain 18 is constructed using a known device (not shown), for example, a pulley is provided on each of the intermediate pillar 10 near the top of the transparent mat 15 having a downward slope, the cross beam 6 near the hem of the transparent mat 15, and the lower part of the block wall 8. By hanging a rope endlessly around the pulley and tying the top opening/closing end of the blackout curtain 18 to the rope, the rope can be automatically opened/closed manually or by means of moving the rope by guiding it through the pulley using mechanical force. It may also be possible to open and close it manually.

Lower space 17 inside the building partitioned by the transparent mat 15
A ventilation fan 19 is installed on the front wall and rear wall of the block wall by removing a portion of the transparent plastic hard plate 9, and an appropriate number of intake ports 20 are installed on the block wall 8 at the bottom of both left and right sides as shown in FIG. Each intake port 20 is provided with a door 21 whose upper portion is locked with a hinge and which can be opened and closed toward the outside.

A shutter 22 is provided at the front entrance of the lower space 17, and a hot air heater (not shown) is installed at an appropriate position within the lower space 17.

Similarly to the above, a ventilation fan 19' is provided on the front wall leading to the upper space 16, and an air intake port that can be opened and closed is provided on the rear wall.

In the lower space 17, a breeding frame, a feeding trough, a drinking fountain, an excrement disposal tank, etc. (not shown) are installed according to the livestock to be raised.

In the above embodiment, the roof of the livestock barn is arched, but the roof is not limited to this, and may be shaped like a raised palm.

In the livestock barn according to the present invention constructed as described above, a transparent plastic hard plate 9 is airtightly stretched and fixed on the outer wall surface, and a transparent mat 15 is installed in the middle and high part of the livestock barn to airtightly connect the upper space 16 and the lower space 17. Since both the upper and lower spaces 16 and 17 inside the livestock barn are partitioned and stretched, there is no air circulation with the outside.
Also, there is no air circulation between the upper and lower spaces 16 and 17.

Therefore, during the daytime during the severe cold season, the light-blocking curtain 18, which is made by polymerizing a vinyl film mixed with aluminum foil strips on the front surface and a white vinyl film on the back surface, is tilted downward to both sides. By opening the transparent mat 15 and pressing the button, even relatively weak light that enters through the transparent hard plastic plate 9 and the transparent mat 15 can control the temperature in the lower space 17, that is, the temperature in the livestock breeding room. By closing the light-shielding curtain 18 at night, the warm air in the lower space that has been stored during the day is transferred to the air [N] between the light-shielding curtain and the transparent mat and the inside of the vinyl film of the light-shielding curtain. The aluminum foil strips block out infrared rays and other harmful elements in the room and keep the room well warm, but in cold regions, ice may form in the attic at night, and when it melts during the day due to sunlight, water droplets form. Even if it falls, it flows along the downwardly sloped transparent mats 15 on both sides and can be guided and discharged into the gutter on both sides.

However, I went back to the livestock barn of the present invention and started rotating the ventilation fan 19.
Stopping, opening and closing of the intake port 20, operation and stopping of the warm air heater at a temperature in the lower space 17 suitable for raising livestock, that is, 16°C ~
Upper limit, lower limit and upper limit of humidity within the range of 20℃ (e.g. 7
5%), the extremely humid and foul-smelling air in the lower space 17 is exhausted to the outside during the severe cold season, and the lower space 17 is refilled with fresh, low-humidity air. Can raise the temperature inside.

In addition, during high-temperature periods, when the blackout curtain 18 is always closed to block sunlight, the high-temperature air in the lower space 17 is continuously discharged to the outside according to the set temperature, and fresh, low-humidity air is inhaled. Since the air flows through the lower space 17, it feels (4 to 7 degrees Celsius) lower than the actual room temperature (in the case of a wind speed of 3 meters) and is comfortable (perceived temperature).

Moreover, during the high temperature period, the ventilation fan 1
It is possible to suppress the temperature rise in the lower space 17 by rotating the air intake port 9, opening the intake port 2σ, and replacing the air with fresh air from outside.

Therefore, no ice or dew condensation occurs on the inner surface of the hard plastic plate stretched on the roof of the upper space 16 and on the surface of the lower space 17 of the transparent mat stretched on the middle and high parts.

The livestock barn according to the present invention opens the blackout curtains during the daytime, except during high-temperature periods, and makes full use of the sunlight, which has immeasurable benefits such as thermal energy, sterilization effect, and vitamin D production, to protect livestock in the lower space, that is, the breeding room. It is possible to significantly improve the environmental hygiene of childcare and breeding, which promotes the healthy growth of livestock, reduces the accident rate, improves productivity, and has the extremely excellent effect of improving the efficiency of livestock management. 0 is something that is
