The present invention relates to a method and apparatus for making compost by mixing dry soil with grass. More specifically, the present invention relates to a method and an apparatus for making compost by injecting air into the soil after maintaining a proper temperature and humidity by mixing finely ground grass to compost large amounts of nutrients.

Until now, the main method has been to make compost by mixing fertilizer and sawdust, fermenting it repeatedly while changing the moisture and turning it into compost.

The mixing of sawdust is to prevent the nutrient balance between nitrogen and carbon because it contains a large amount of nitrogen in the pork stock, and thus ammonia is lost during fermentation. Even if urine (moisture) is separated in the pretreatment process, the moisture content is more than 90%, so the fermentation temperature is not increased and there is a risk of corruption.

However, sawdust is a lignin ingredient with a long fermentation period, causing malodors such as ammonia gas to turn over, making it a target for complaints, sawdust price being expensive, and difficulty in obtaining, resulting in costly processing of livestock.

In order to solve the above problems, the present invention is a sawdust that has a high nitrogen content but a low carbon content (less C / N ratio) to make the compost, a time-consuming in the fermentation of pig water containing a high moisture content To provide a method and apparatus for composting in a short time without mixing.

It is also an object of the present invention to provide a method and apparatus for composting livestock without causing malodor.

In order to achieve the above object, the present invention is to mix the finely chopped grass and dry soil with the shaft powder and then buried the mixed lumps in the corrosive soil provided in the composting tank formed on both sides and the bottom of the water film An apparatus is provided for composting by injecting soil microorganisms into an air tube installed at the top of the tank bottom.

More specifically, a grass is provided, and a tool for cutting the grass is provided to finely cut the grass and mix the shaft powder with the cut grass. Mixing grass to animal feed is to balance the nutrients that are essential for making compost. In order to compost organic matter, it is usually necessary to balance carbon and nitrogen properly. It is known that the -35 range is appropriate. However, the content of carbon as organic matter is less than that of nitrogen, and the amount of carbon is absolutely insufficient compared to the composting range of organic matter, which usually has a C / N ratio of 4 to 8 and requires a range of 20 to 35. In the conventional composting, sawdust was used to compensate for this, but sawdust has a long time for fermentation due to lignin, so it has a disadvantage of being bulky and large. In the present invention, in order to compensate for the above problems, instead of sawdust, it is characterized by mixing finely cut grass (草).

In addition, the present invention is characterized by mixing the dry soil for moisture control of the mixed axial fraction with the grass undergoing the above process. The composting compost needs the proper moisture content. If the moisture content is low, the condensate is not fermented and tends to be dried. If the moisture content is high, the aeration is not allowed, and rotting occurs, causing odor.

The water content of the finished compost is about 50 to 60%, but in the case of nutrients, that is, even after separating urine (water) and powder, the water content is still above 90%. There are a lot of bad breathability and fermentation is not good, rotting phenomenon appears, causing side effects such as causing odor. Therefore, it is necessary to adjust moisture appropriately. The reason why the sawdust is mixed so far is that the sawdust has a water content of about 40 to 60%, which can serve as a moisture control agent.

However, sawdust is expensive and difficult to obtain, the patent has the feature of using it as a moisture control agent by replacing it with dry soil. Dry soil may have a moisture content of less than 10% even in the sun alone, and fresh soil can be used as a moisture control agent with a moisture content of less than 50%. In addition, there are numerous microorganisms in the soil, which promotes the composting.

After the above process, the mixed soil and grass mixed with the soil is buried in the composting tank which is previously provided in the composting tank formed on all sides and the bottom surface, and then air is supplied through the air inlet pipe installed on the bottom of the composting tank. Promotes the activity of infused soil microorganisms and proceeds with composting.

Hereinafter, a method and an apparatus for composting after mixing the stock with grass and dry soil in accordance with the method of the present invention and buried in the soil microorganisms will be described in detail as follows.

Figure 1 is a view of the device for composting after mixing the shaft stock with grass and dry soil in accordance with the method of the present invention and then buried in soil microorganisms.

      First, the pile heap 1, the grass pile 2 and the dry soil 3 are provided. The provided pile 2 is provided after being finely crushed by the pool cutting crusher 2-1.

The shaft powder 1 and the grass pile 2 and the dry soil 3 provided as described above are mixed by the mixer 4 so as to form a lump 4-1. In this process, the axial fraction (1) is mixed with the grass pile (2) and the C / N ratio is controlled, and the moisture is controlled while being mixed with dry soil.

The tube 4-1, which has undergone the above-described process, is transferred to the composting tank 6 soil microorganism (soil) 6-2 by the transfer device 5, and is buried to be composted.

Composting tank (6) is formed in all sides and the bottom of the water film (6-1), the air supply pipe (8) is installed on the top of the bottom of the tank (6), the air supply pipe (8) Brows 7 are provided for supplying air. The air supply pipe (8) is protected by a nonwoven fabric (8-1), the soil microorganisms (soil) (6-2) is installed on the top of the nonwoven fabric.

The tube 4 buried in the soil microorganism 6-2 receives air from the air supply pipe installed at the bottom of the tank 6, and the aerobic microorganisms are activated, thereby promoting metabolism by the microorganisms, thereby promoting composting.

Through the above process, the nutrient is characterized by being composted with grass and soil. In addition, there is a characteristic that the odor is not induced due to the composting by burying the lump (4) in the soil microorganisms.

Soil is decomposed and destroyed by microorganisms during the process of decomposing and extinguishing organic matter, but some are corroded and stored as nutrients, and at the same time, it promotes granulation and makes humus.
In the case of livestock, the moisture content is about 80% at the beginning, but in the case of pigs, it is difficult to separate urine. The dry grass, which is mixed with -30% and mixed to supply carbon, is also mixed with 10-30% of the outer volume of the stock, making a lump, and then buried in soil microorganisms for composting.

Looking at the method and the device effect for making the compost by mixing the dry soil and grass (grass) according to the present invention, the compost can make compost by mixing grass and dry soil without the conventional sawdust Easily available and cheaply available has the effect of making compost economically.

In addition, the facility cost is low because the facility is simple, and the soil can be obtained at unlimited low price anywhere in Korea, and the operation cost is low. It has an effect.
