Connected to 179a.

In addition, a chain 178 for passing the larva on the wire mesh to the bottom of the wire mesh is installed in the same structure as the chain 163 on the upper portion of the wire mesh 177a.

Unexplained symbol A is livestock manure.

In the present invention configured as described above, livestock manure is supplied to the blender 12 by the transfer screw 10 and at the same time when the livestock manure is dried to adjust it to about 80% when the water content of the livestock manure is about 80%. It is supplied to the mixer 12 by the conveying screw 11.

When the livestock manure and dry livestock manure are supplied with appropriate amounts, respectively, as described above, the mixer 12 is operated to properly regulate the water content, and then discharged to the discharge port 122, and the flat of the larval supply means 13 installed thereunder. It falls to the upper surface of the belt conveyor 131. At this time, the flat belt conveyor 131 is gradually moved in the direction of the arrow (left direction) as shown in Figure 2 and soon the manure on the upper surface of the flat belt conveyor 131 is laid flat enough to the appropriate thickness and the entire upper surface When completely laid flat belt conveyor 131 is stopped rotation.

Livestock manure spreading means 14 is required to livestock manure on the flat belt conveyor 131 to be flat as appropriate thickness. The livestock manure spreading means 14 is installed on the upper right end according to the drawing reference of the flat belt conveyor 131, as shown in Figure 4, it is to spread the livestock manure to the diffusion rod (143) do. That is, the time belt 142 is rotated forward and backward by a predetermined width by the driving of the motor 141, so that the diffusion rod 143 fixed to the time belt 142 is also reciprocated in the direction of the arrow of FIG. Livestock manure poured on the upper surface of the belt conveyor 131 is flattened.

In addition, since the flat belt conveyor 131 is mounted on the reciprocating frame 132, after the livestock manure is completely supplied, the frame observing device 134 is operated to make the reciprocating frame 132 as shown in FIG. By pulling to the left side so that the right end of the flat belt conveyor 131 deviates from directly below the discharge port 122, the livestock manure supplied from the discharge port 122 is directly fed to the culture vessel 151 of the larval culture means 15. Let it fall

The fly manure is sprinkled on the livestock manure on the flat belt conveyor 131 using a separate feeder (not shown), and after about one day, the fly eggs hatch to generate baby larvae. Distribution is introduced into the culture vessel 151 of the first culture means (15a).

After one full day in the culture vessel 151 of the first culture means 15a, it is transferred to the culture vessel of the second culture means 15b, and the third culture means 15c after another day in the second culture means 15b. After transferring to the fourth culture means (15d) again in one day, and after another day, the larva grows up to just before the pupa.

The larvae grow actively by feeding livestock manure while staying in the first culture means 15a to the third culture means 15c. Through this process, the livestock manure becomes a good fertilizer with little odor. . In the meantime, the through hole (e) of the culture container 151 supplies oxygen to the inside of the livestock manure to prevent deterioration of the living environment of the larva such as rotting of the livestock manure and both side walls (b) of the culture container 151 and the front and rear Since the wall (c) is made of a vertical wall to prevent the escape of the larvae, the loss of the larvae can be minimized.

The larvae in the fourth culture means (15d) are released from the livestock manure (already fertilized) in order to become a pupa, and because of the instinct to go to the pupae-friendly environment, most of the larvae through the through hole (e) The larvae fall down from the culture vessel 151 of 15d, and thus the larvae are collected at a predetermined place by the larva receiving plate 171 of the larva gathering means 17.

Even if most of the larvae escaped freely, many still remain in the livestock manure in the culture vessel 151, and it is necessary to separate the larvae from the livestock manure.

The larvae are of high value because of their high protein feed.

In this way, the livestock manure of the fourth culture means (15d) is transferred to the larva separation means 16 to separate the larva still remaining in the livestock manure.

As shown in FIG. 8, the dismantled livestock manure poured down into the larva separation means 16 accumulates northwest on the wire mesh 166, which is rotated along both chains 163 while the chain 163 rotates to spread along the chain. It is pushed out to the right by the chain 164.

At this time, the diffusion chain 164 is loosely installed as shown in FIG. 7 so that the diffusion chain 164 moves while sliding the upper guide rail 165, and the livestock manure on the wire mesh 166 by the continuous operation of this movement. Gradually moves to the right.

Since the diffusion chain 164 moves while friction with the guide rail 165 in the lower part, the livestock manure is forced from the lower part, and the upper part is inverted, so the larvae staying in them escape downward in their habits. After hitting the end through the wire mesh 166 installed under the guide rail (165) will fall down.

In this way, all the larvae separated from the livestock manure are gathered at the lowest vertex made of the inclined surface 171a of the distribution plate 171, and the cover 172 floating in the air as shown in FIG. When the vacuum pump 179 of FIG. 11 is gradually closed, the larva on the larva receiving plate 171 starts to be absorbed by the larva near the left end of the cover 172 and the cover 172 is completely closed. All are vacuum absorbed.

In this manner, the larvae absorbed in the vacuum are mixed with a large amount of fine powder fertilizer larvae and squeezed out of the wire mesh 166. Their larvae and fine powder fertilizers are reselected in the larval collection chamber 177 of FIG.

That is, when the fertilizer and the larvae of the fine powder enter the inlet (177d) side, the fertilizer is light, so it falls on the loading station (177f), and the larvae are heavier than the fertilizer, so it falls on the wire mesh (177a) and the chain (178) When the wire mesh 177a is shaken by larvae, the larvae are collected in the larva collection box 177b provided under the wire mesh.

In addition, the fertilizer piled up at the loading place 177f increases when the loading amount increases, and the opening and closing door 177c is automatically opened and poured out.

When the door 177c is opened, the operation of the vacuum pump 179 is stopped in a separate switch device (not shown) and the vacuum pump 179 is operated again when the door is closed. Will be.

In the present invention described above, in the production of larvae and fertilizers during the treatment of livestock manure, the entire system has been shortened in line with the conventional treatment apparatus, thereby greatly reducing installation costs and reducing maintenance costs and power energy consumption. It is effective in increasing the treatment efficiency of manure and producing high quality larvae and fertilizers.
