Description

  The present invention relates to a barn for fattening livestock such as pigs, cows, sheep, and chickens.

  In Japan, various livestock such as pigs, cattle, sheep and chickens are raised in barns. As a method for treating such excreta excreted from livestock, for example, a method is generally known in which sawdust (wood cutting waste) is laid in a domestic cell to adsorb livestock excreta.

  In this method, sawdust is laid on the floor in a barn (livestock breeding area) surrounded on four sides by shelf frames, and livestock is raised therein. Then, the excrement excreted daily by livestock is adsorbed to sawdust, and the sawdust is replaced with a new one at regular intervals. In this replacement work, the livestock is moved to another barn, old sawdust is discharged using machines and manpower, and new sawdust is laid.

  However, in such a method, since the excrement adsorbed by the sawdust is kneaded with the sawdust, the sawdust becomes dirty with the excrement over time. For this reason, it is indispensable to replace every certain period. However, in practice, the replacement and cleaning of sawdust every certain period tends to be delayed, and in the worst case, livestock is raised in a barn full of manure. In such a case, hygiene is extremely poor, and in some cases, highly toxic viruses and parasites may be generated.

  In addition, since sawdust mixed with manure is accompanied by ammonia gas, dust, and hot air from fermentation, the replacement work in the animal tub is extremely severe for the operator. Therefore, if such work is continuously performed for a long period of time, there is a high possibility that the health of the worker is harmed.

  Furthermore, when exchanging work in the animal house, it is necessary to move livestock such as pigs to empty animals or other animal animals. However, if this is done on a regular basis, it will cause great stress on the livestock and consequently adversely affect the growth of the livestock.

  In recent years, there are concerns about the outbreak and epidemic of new highly toxic viruses such as Thurs and avian influenza. In order to prevent the spread of such new viruses, it is necessary to improve the hygienic conditions of the barn on a global scale.

  Therefore, in view of the above-described background, the object of the present invention is to maintain and manage with less labor compared to the conventional technique, and to maintain a good hygiene condition at all times, and to the operator and the surrounding environment. The purpose is to provide harmless barns.

  Such an object is achieved by the present invention described in the following (1) to (12).

(7) The livestock barn according to (6), wherein the manure pit is partitioned into a plurality of individual manure pits, and the scraper is provided in each of the plurality of individual manure pits.

(8) The barn according to (5), wherein the aeration tank is provided at a lower position than the excreta pit.

(9) The animal shed is constructed on the ground, the aeration tank is constructed underground, and the manure pit is constructed at a height position between the animal tub and the aeration tank. The barn according to (8) above, which is characterized.

(10) The barn according to (5), further comprising a cleaning device for automatically cleaning the floor plate of the barn with water.

(11) The barn further includes a reaction tank for spraying the sludge water from the aeration tank, and at least a part of the treated water obtained through the reaction tank is used as the aeration tank. The livestock barn according to (5) above, wherein the barn is configured to be inserted into the barn.

(12) The livestock barn according to (11), wherein each of the aeration tank and the reaction tank contains a porous material supporting microorganisms.

According to the present invention, manure excreted by livestock falls to the floor immediately after excretion without being deposited on the floor of the livestock. Therefore, a situation in which the inside of the slaughterhouse is full of manure is not generated, and the hygienic condition in the slaughterhouse can be kept good. As a result, for example, it is possible to prevent the occurrence of parasites and the like in the domestic animal, and it is possible to develop the animal without causing stress to the livestock.
Further, even if the livestock moves around in the livestock, it does not come into contact with manure, so manure does not adhere to the body surface, and the health of the livestock can be maintained well.
Furthermore, as a result of being able to keep the hygienic condition in the animal bar in a good condition at all times, it is possible to prevent the generation of bad odors and hot air, thereby improving the workability of workers in the animal barn.

  Moreover, according to this invention, the manure which fell to the manure pit via the floor board is automatically scraped up by the scraper provided under the floor. This eliminates the need for an operator to discharge manure, so that livestock can be raised with less labor than in the past.

  Further, according to the present invention, the manure dropped into the manure pit via the floor board is thrown into the aeration tank by the scraper. Since the manure put into the aeration tank is bioprocessed immediately after the addition (process for decomposing organic matter by the metabolism of microorganisms), it does not undergo anaerobic fermentation and can suppress the generation of malodor. Therefore, it is possible to prevent the surrounding environment and the environment in the barn from deteriorating due to a bad odor.

  Furthermore, according to the present invention, the manure dropped into the manure pit via the floor board is periodically introduced into the aeration tank by the scraper. Therefore, since the amount of manure exceeding the processing capacity is not thrown into the aeration tank at once, it becomes possible to reliably bioprocess the manure put into the aeration tank.

  Furthermore, according to the present invention, the aeration tank is provided at a lower position than the manure pit. Thereby, manure can be easily thrown into an aeration tank using the dead weight of manure.

  Furthermore, according to the present invention, the floorboard of the livestock is regularly automatically washed with water. As a result, feces and urine adhering to the floor plate of the animal can be washed away, so that the inside of the animal can be kept in a more hygienic state and the workability required for cleaning the animal interior can be improved. it can. Moreover, since the water used for washing | cleaning will be thrown into an aeration tank through a floor board, it will also contribute to the effective reuse of water resources.

  In addition, in the present invention, the following excellent effects can be achieved by using cedar (cedar chips) as the porous material.

Hardwoods are susceptible to spoilage because there are no holes in which cocci dwell. On the other hand, in the case of conifers, Karamatsu is oily. In addition, hiba and cypress have a strong antibacterial action and are not suitable for living microorganisms. In contrast, the cedar tree there is a hole of about 8 million units / m ^2, it can be said to be suitable for settle microorganisms.

  The cedar chips used in the present invention are processed so as to be porous, and in the production process, cellulose and hemicellulose contained in cedar components are partially saccharified. Therefore, the environment has been optimized so that microorganisms can easily live on cedar chips as a result of being made porous, and the generation of microorganisms for fermentation, decomposition and digestion of BOD sources by partially saccharifying cellulose and hemicellulose・ Proliferation nutrients will be created.

  In addition, cedar wood has an advantage of low viscosity and low specific gravity. Therefore, it is possible to keep power cost required for stirring in the apparatus of the aeration tank low.

In addition, each municipality such as the Tokyo Metropolitan Government has set a numerical target of cutting cedar forest and planting cedar forest with less pollen to reduce cedar pollen by about 20% in 10 years as a drastic source of hay fever. ing. However, as for the large amount of thinned cedar wood that is generated by the felling, no effective use method has been proposed yet, and it is difficult to dispose of it.
Therefore, by actively utilizing “cedar wood” as a raw material of the wood strips used in the present invention, it is possible to effectively reuse the thinned cedar wood that is generated along with the felling.

Hereinafter, the barn according to the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a plan view showing a schematic configuration of a barn 1 according to the present invention.
FIG. 2 is a diagram showing an outline of the underfloor structure of the barn body 11 of the barn shown in FIG.
FIG. 3 is a cross-sectional view of the barn body 11 taken along line AA in FIG.
FIG. 4 is a cross-sectional view of the barn body 11 taken along the line BB in FIG.
The kind of livestock that can be raised in the barn according to the present invention is not particularly limited, and can be applied to various kinds of livestock such as pigs, sheep, cows and birds.

The barn 1 mainly includes a barn main body 11 and a manure processing system. The barn main body 11 mainly has livestock 21 to 23 for raising livestock. The manure treatment system includes an aeration tank 31 constructed in the basement of the barn body 11, a raw water tank 32 provided outside the barn body, a treated water tank 33, a reaction tank 34, and a deodorizing water tank 35. It is configured to include.
Hereinafter, the configuration of the barn 1 will be described in detail.

  As shown in FIG. 1, the barn main body 11 has a plurality of barns whose both sides are sandwiched between passages. In the present embodiment, the first barn 21, the second barn 22, and the third barn A livestock 33 is provided. Each of the slaughterhouses 21 to 23 where the livestock is fattened is partitioned on all sides, and two feeding areas and one resting area are provided in each slaughterhouse. Livestock in each animal can go back and forth between the feeding area and the resting area according to a predetermined condition.

  The floor board 3 provided on the bottom surface side of each of the livestock 21 to 23 is formed from a slatted floor board in which a gap is formed. The livestock is active on the floor board 3, and the excreta excreted by the livestock almost immediately adheres to the body surface of the livestock and falls immediately below the floor through the gap between the slat-like floor boards.

  In the present invention, the material to constitute the floor board 3 is not necessarily limited to the slats, and any material can be used as long as a through hole and / or a gap through which excrement passes is formed.

  On the side walls, ceiling, or floor of the slaughterhouses 21 to 23, a cleaning device (not shown) (for example, a shower) is provided. The excrement stuck to the floor board 3 without falling below the floor is washed away by this washing device and falls to the bottom together with the washing water.

  As shown in FIGS. 2 and 3, a manure pit 5 is constructed under the floors of the first and second livestock chambers 21 and 22 to accommodate manure falling through the floor plate 3. Yes. The manure pit 5 is divided into a plurality of individual manure pits. In the present embodiment, the manure pit 5 is divided into eight individual manure pits 51. The bottom surface of the manure pit 5 may be provided with an inclination so that manure can easily flow in the direction of the aeration tank 31. Moreover, the groove | channel for isolate | separating feces and urine may be provided.

  Each individual manure pit 51 is provided with a scraper 61 for collecting manure that has fallen through the floor board 3. Each scraper 61 is composed of a rigid body such as an iron plate, and is connected to a corresponding drive motor 63 via a rope 62 (see FIG. 3). Each drive motor 63 is connected to a predetermined control device and is driven periodically. When the drive motor 63 is driven, the corresponding scraper 61 slides back and forth along the side wall in the individual manure pit 51.

  As shown in FIGS. 2 and 3, an aeration tank 31 for aeration treatment of manure is constructed under the floor of the third animal chamber 23. The aeration tank 31 is constructed at a lower position than the adjacent excreta pit 5. In the present embodiment, the slaughterhouses 21 to 23 are constructed on the ground, whereas the aeration tank 31 is constructed underground, and the manure pit 5 is constructed at a height position between the slaughterhouse and the aeration tank. (See FIG. 3).

  The manure collected by each scraper 61 in the manure pit 5 is periodically introduced into the aeration tank 31 by the scraper.

  Next, a manure processing system provided in the barn of the present invention will be described.

In the manure processing system, liquid fertilizer (reduced organic nutrient solution) is manufactured through two processing steps. One is a wet process by “aeration (in-water treatment)” in the aeration tank 31 and the other is a dry process by “microbe filtration reaction” in the reaction tank 34 following the wet process. The treated water finally obtained through the reaction tank 34 can be used as liquid fertilizer (nutrient solution) in organic cultivation of agricultural products.
Hereinafter, features of the manure processing system will be described in detail.

  Inside the aeration tank 31, a porous material carrying microorganisms for bioprocessing sludge water is spread, and an accelerator for growing microorganisms is added. This porous material can be composed of, for example, any one of strip-like cedar, charcoal, bamboo charcoal, or a combination of two or more thereof. Innumerable pores are formed in such a porous material, and the pores contain abundant microorganisms necessary for bioprocessing and bait of the microorganisms.

  The aeration tank 31 is filled with feces and urine discharged by the livestock in the first and second livestock chambers 21 and 22 by the scraper 61. In addition, the manure produced in the third slaughterhouse 23 falls as it is and is put into the aeration tank 31. Thus, the manure put into the aeration tank 31 is diluted with water in the tank, and as a result, sludge water containing organic matter is generated.

  In the aeration tank 31 for storing sludge water, wet processing is performed by underwater aeration. That is, in the aeration tank 31, there is a rapid growth of aerobic bacteria and anaerobic bacteria due to aeration and contact agent, and the BOD source of sludge is extinguished. And the sludge water aerated in the aeration tank 31 is sent out to the reaction tank 34 by pump-up.

  Like the aeration tank 31, a strip-shaped porous material is accommodated in the reaction tank 34. The sludge water (treated water) flowing from the aeration tank 31 is mainly in the form of floating fine particles, and the final treatment is performed in the reaction tank 34. The sludge water that has flowed into the reaction tank 34 contacts the porous material in the reaction tank, and is further decomposed by microorganisms.

  That is, in the reaction tank 34, the sludge water from the aeration tank 31 is sprinkled and the BOD source of sludge is completely extinguished by the microbial contact filtration reaction. As a result, harmless and odorless liquid fertilizer suitable for organic farming is produced. Since the obtained liquid fertilizer is in a reduced state, it does not oxidize and does not rot even if left for several years. Further, according to the component analysis of the present inventor, it has been confirmed that the liquid fertilizer contains abundant components preferable for the growth of agricultural crops and does not include any components that are harmful to the human body or the environment. It was.

  Treated water (liquid fertilizer) from the reaction tank 34 is temporarily stored in a downstream tank. Part of the sludge water stored in the tank is used as liquid fertilizer in organic cultivation, and the rest is returned to the aeration tank 31. In addition, when using the obtained treated water as liquid fertilizer, you may give to a crop as it is, or you may give to a crop after performing a predetermined component adjustment.

  In the livestock barn described above, the kind of porous material to be accommodated in the aeration tank 31 and the reaction tank 34 is not particularly limited, but it is preferable to use a wood strip (cedar chip) formed from a cedar thinning material. It is preferable that the wood strip is processed so as to have a quality. When cedar wood is used as a raw material for wood chips, lignin, which is a component of cedar wood, becomes water-soluble lignin in the above manufacturing process. Even if it doesn't rot, it keeps odorless.

  Further, when cedar chips are used as the wood chips, it is preferable that cellulose and hemicellulose in the components contained in the cedar are partially saccharified. Moreover, it is preferable that this cedar chip | tip contains 65-85% of cellulose bodies, 10-25% of lignin bodies, and 5-10% of pentozan bodies.

According to the above-described present invention, manure excreted by livestock falls to the floor immediately after excretion without being deposited on the floor of the livestock. Therefore, a situation in which the inside of the slaughterhouse is full of manure is not generated, and the hygienic condition in the slaughterhouse can be kept good. As a result, for example, it is possible to prevent the occurrence of parasites and the like in the domestic animal, and it is possible to develop the animal without causing stress to the livestock.
Further, even if the livestock moves around in the livestock, it does not come into contact with manure, so manure does not adhere to the body surface, and the health of the livestock can be maintained well.
Furthermore, as a result of being able to keep the hygienic condition in the animal bar in a good condition at all times, it is possible to prevent the generation of bad odors and hot air, thereby improving the workability of workers in the animal barn.

  Moreover, according to this invention, the manure which fell to the manure pit via the floor board is automatically scraped up by the scraper provided under the floor. This eliminates the need for an operator to discharge manure, so that livestock can be raised with less labor than in the past.

  Further, according to the present invention, the manure dropped into the manure pit via the floor board is thrown into the aeration tank by the scraper. Since the manure put into the aeration tank is bioprocessed immediately after the addition (process for decomposing organic matter by the metabolism of microorganisms), it does not undergo anaerobic fermentation and can suppress the generation of malodor. Therefore, it is possible to prevent the surrounding environment and the environment in the barn from deteriorating due to a bad odor.
