[0002]

2. Description of the Related Art Since livestock manure such as cow dung is not easily used for secondary purposes due to its bad odor, etc., most of it is currently discarded as industrial waste, and it is economical to dispose of it. The treatment of livestock manure is a very important issue for livestock breeders because it is accompanied by an economic burden. For example, when about 50 cows are raised by a general average breeder, about 2 tons of cow dung is generated per day,
This large amount of cow dung cannot be easily processed.

For this reason, it takes about 1 to 3 years to repeat mixing and stirring with compost to make livestock manure into fertilizer, and during that time, not only a bad odor is generated but also ripeness is difficult. In other words, the livestock manure that has been generated for about 1 to 3 years is collected, and even if it is mixed with compost and stirred, a bad odor is released to the surroundings by various bacteria that have propagated.
In addition, a new bacterium is constantly mixed in by stirring, so that the bad odor does not disappear, and the bad odor is emitted from the fertilized fields to cause environmental pollution.

A plant for fertilizing livestock manure has also been proposed, but this plant mixes livestock manure with straw, a water content adjusting material and the like by a mixer and then mixes predetermined bacteria into a fermenter. It is fermented, crushed, dried and fertilized.

[0005]

As a result, the fertilizer cannot be fully ripe, and the finances of breeders are being squeezed, and the plant itself is very difficult to install due to lack of equipment funds.

Therefore, the present invention has been made in view of the above-mentioned existing circumstances, and appropriately mixes livestock manure and a water content adjusting material, pulverizes after mixing, adjusts and controls the conveying amount, and compresses. It is possible to easily carry out a series of processes such as kneading while mixing, facilitating fermentation due to heat generated by friction, and promoting contact with air by crushing after heating and kneading. It is an object of the present invention to provide an organic fertilizer manufacturing apparatus that is miniaturized as a whole and that can be treated hygienically and quickly without generating a bad odor.

Heat is generated by friction with the piece 33 and further with the feeding obstruction means 45 that enters the heating chamber 30, and the fermentation of the livestock manure B etc. is promoted. In the livestock feces B etc. in which fermentation is promoted, various bacteria other than effective bacteria are killed and the source of malodor is removed, whereby the whole is deodorized, and deodorization is used as a fertilizer material.

Even when the pressing piece 33 is pressed in the heating chamber 30 to solidify it, when the outlet opening 35 of the partition wall 34 is opened by the shutter opening / closing means 37, the rear portion of the pressing shaft body 31 is fed. Heating chamber 3 with blades 32
It is possible to forcibly convey the livestock manure B or the like after heating and kneading to the front of 0 and carry it out to the crushing discharge chamber 50. Then, the progress of the heating and kneading in the heating chamber 30 can be easily performed by adjusting the transport amount in the crushing chamber 20, adjusting the carry-out amount of the livestock manure etc. B by opening / closing the shutter opening / closing means 37, adjusting the feeding obstruction means 45, etc. It can be controlled.

In the crushing discharge chamber 50, the rotating discharge shaft 51 is rotated.
Since the crushing and discharging piece 52 of No. 2 is used to crush the livestock manure B etc. which has been heat-kneaded and solidified in the heating chamber 30,
It is possible to make the livestock manure and the like B carried out from the carry-out port 35 of the partition wall 34 fine and to bring it into contact with a larger amount of air to promote the fermentation and use it as fertilizer and the like.

Further, a vast average treatment of about 2 tons of cow dung etc. generated per day by a general average breeding operator,
With the apparatus of the present invention, almost 1
The cow dung and the like can be easily treated on a daily basis, and can be economically used at a very low cost if the breeder installs it himself.
