Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a livestock pen suitable for raising livestock, particularly for raising pigs.

Among livestock, pigs are known to be polyphagous and excrete an extremely large amount of urine. Traditionally, when raising pigs, it is necessary to process a large amount of manure, so the floor of the livestock barn is tilted to one side with a concrete surface. Generally speaking, large amounts of excrement and urine are collected in one place and then disposed of, but this method requires a huge investment in excrement treatment facilities and has limitations on the release of purified water and environmental sanitation. There is an inconvenience in that a specific type of light is required. For this reason, recently,
Attempts have been made to treat the manure by spreading a large amount of sawdust mixed with aerobic fermentation bacteria on the rearing floor, allowing the sawdust to absorb the manure and decomposing it with the fermentation bacteria.

This method is advantageous in the winter due to the fermentation heat, but since aerobic bacteria require a supply of air, it is necessary to constantly turn over the fermentation bed, and if this management is insufficient, livestock The disadvantages include that the sawdust is trampled, which prevents aerobic fermentation and generates harmful gases such as ammonia gas due to anaerobic fermentation, and livestock can become ill if they eat the incompletely fermented sawdust. In contrast, the present invention performs fermentation treatment using sawdust and forms the rearing floor in a slat shape so that livestock can
In order to avoid direct contact with the sawdust, hot air is constantly sent from the bottom of the sawdust, and the bonito sawdust is automatically stirred to improve the efficiency of ventilation drying. An embodiment of the present invention (a fattening pigsty) will be explained with reference to the drawings.The whole livestock shed 1 has fences 2...
It is divided into several rooms 3... each with an enclosure fence 4.

The lower part of these chambers 3... is formed into a series of manure fermentation tanks 5 spanning the entire length of the livestock barn 1, and the floor surface of each chamber 3...
A large number of slat plates 7 are removably screwed onto beams 6 provided across the fermenter 5, and the inside of the fermenter 5, which is formed on a slat-like floor surface, is hardened with concrete. It can be installed above ground, underground, or semi-underground. As shown in FIG. 4, rails 9.9 are attached to the inner wall of the fermenter 5 along the longitudinal direction through receiving members 8, 8... 1
0 is engaged with the rack. As is clear from the figure, this traveling trolley 10 has a drive axle 12 and a stirring rotation shaft 13 attached to a frame 11, and a motor 14, which is provided on the frame 11, respectively. The axle 16...the stirring horn 17 are rotated by Is.

This traveling cart 10 can be moved longitudinally within the fermentation tank 5 via an operation panel provided at a suitable location in the livestock barn 1, and the stirring horn 17 can be operated at any time. An air blowing pipe 18 is installed on the concrete floor of the fermentation tank 5 to supply air to the aerobic fermentation bacteria as needed via a blower installed outside the livestock barn 1. It has become. This invention has the above-mentioned structure, and as described above, a large amount of sawdust a is stored in the fermenter 5, and fermentation bacteria are sprayed and mixed into the sawdust from time to time, that is, high-temperature bacteria in the winter and low-temperature bacteria in the summer. The animals are reared on the slat plates 7 in each chamber 3 while maintaining the slats, and the excreted manure permeates the sawdust a through the slats and is decomposed by fermentation bacteria, and the moisture is absorbed by the fermentation heat. The mechanism is such that it evaporates.

In this way, warm air is sent from the bottom surface of the rice slag through the air blowing pipe 18 at any time, and the traveling trolley 1 ( ) is moved to stir the top surface of the slag a, thereby decomposing and removing water on the average over the entire surface of the fermenter 5. Promote evaporation. The volume of deposits such as excrement, urine, and sawdust in the fermentation tank 5 decreases little by little due to evaporation and decomposition of water, so fresh sawdust is replenished from time to time. This will add the following. In addition, in winter, fermentation bacteria use fermentation heat to warm the room temperature, so thermophilic bacteria are used, and in summer, psychrotrophic bacteria with a low fermentation temperature are used to prevent the room temperature from rising. Since they are sensitive to heat, the structure of the barn should provide sufficient ventilation during the summer. In addition, the air blowing pipe 18
It is possible to control the fermentation temperature to some extent by adjusting the temperature, blowing time, etc. of hot air. and,
When cleaning livestock barns after a certain period of time (minimum - one year),
The slat board 7 is removed and the deposits are taken out of the house, but this jl can be used by plants as high-quality fertilizer. Note that a method for removing the deposits may also be considered by using the traveling trolley 10 and discharging them onto the short side of the livestock barn 1.

This invention eliminates the need to transport manure and urine outside the livestock barn, and therefore eliminates the need for sewage treatment equipment that requires a large amount of investment. The amount of bacteria coming into contact with harmful bacteria is drastically reduced, and since fermentation is completed, the generation of harmful substances is reduced, and an appropriate amount of moisture is replenished by water evaporation, so there is no emission of dust, and the odor in the building is drastically reduced. This creates an environment suitable for raising livestock. Furthermore, since the rice shavings are automatically mixed in the fermenter below the floor, there are many advantages such as labor saving.
