Further, a first motor 35a that is driven independently of the driving of the traveling motor is provided, and the first bearing 36a is extended downward from the left and right side edges facing the first motor 35a. Further, a second motor 35b and a second bearing 36b having the same configuration are provided in front of the traveling direction (white arrow in the figure).
The second bearing 36b has a shorter arm length than the first bearing 36a.

The first moving wheel 32 has a first rotary shaft 37a rotatably mounted between the first bearings 36a, and first plowing pawls 38a are radially formed on the peripheral surface of the first rotary shaft 37a. In the illustrated embodiment, the length of the first tilling claw 38a is set so that the diameter of the first moving wheel 32 is substantially the same as the depth of the processing tanks 2A, 2B for storing chicken manure. It is adjusted. The tip of the first tillage claw 38a is bent in the rotational direction, and the first tillage claw 38a is spirally provided on the circumferential surface of the first rotating shaft 37a, so that the resistance load of livestock manure is averaged. It is planted so that Then, the first tilling claw 38a rotates so as to scrape up the livestock manure and agitates the livestock manure.
In order to rotate 2, the endless first chain (not shown) was hung and connected between the first motor 35a and the first rotating shaft 37a. The structure of the first driving wheel 32 is substantially the same as the driving wheel of the conventional stirring device described above.

Further, the second moving wheel 33 is provided with a traveling frame member 31.
Of the first moving wheel 32, which is provided on the front side in the advancing direction of the above and is close to the first moving wheel 32 and has a different size.
It has a configuration substantially similar to. That is, the second rotary shaft 37b is rotatably mounted between the second bearings 36b, and the second plowing claws 38b are radially arranged on the peripheral surface of the second rotary shaft 37b. Further, in the illustrated embodiment, the length of the tilling claws 38a, 38b is adjusted so that the diameter of the second moving wheel 33 is located above the first rotating shaft 37a of the first moving wheel 32. The tip of the claw 38b is bent in the rotation direction. Then, in order to rotate the second driving wheel 33,
An endless second chain (not shown) was hung and connected between the second motor 36b and the second rotating shaft 37b.

At the rear part of the stirring device 3, a odor collecting hood 7 that moves together with the stirring device 3 is provided. This odor collecting hood 7
Is formed in a roof shape with an open lower surface, and the convergent end 71 that opens is in communication with a deodorizing duct 61 of the circulation blower 6 described later. In addition, a odor collecting ventilation fan 74 is provided near the convergent end to guide the air containing water vapor and odor generated from the chicken manure treatment tank 2 to the deodorizing duct 61.

It is preferable that the odor collecting hood 7 has a lower edge located near the upper surface of the stored chicken manure because odor and the like are less likely to leak to the outside, but the advancing direction of the stirring device 3 is changed as described later. I have to do it. Therefore, in this embodiment, although not shown, an elevating means for raising and lowering the odor collecting hood 7 is provided so that the odor collecting hood 7 does not interfere with the outer wall 21 and the partition wall 22 of the poultry manure treatment tank 2 when changing directions. ing.

The deodorizing duct 61 extends in the longitudinal direction at the center of the upper part of the first processing tank 2A and communicates with the odor collecting hood 7. For this reason, in the illustrated embodiment, the opening / closing lids 62 ... Of a size that substantially coincides with the intake port 72 opened at the converging end 71 of the odor collecting hood 7 are arranged in a row in the longitudinal direction.
One side edge is hinged so that it can be opened and closed with a hinge.

On the other hand, a wedge-shaped push-up cam portion 73 is provided on the odor collecting hood 7 side so as to project therefrom. When the odor collecting hood 7 moves forward together with the stirring device 3, the opening / closing lid 62 is pushed open by the cam portion 73, and the odor collecting hood 7 and the deodorizing duct 61 communicate with each other. Then, when the stirring device 3 further advances, one opening / closing lid 62 that has been pushed open is disengaged from the cam portion 73 and rotates by its own weight to close the lower surface of the deodorizing duct 61, and the next opening / closing lid 62 is opened. It is pushed open by the cam portion 73. In this way, when the stirring device 3 moves forward, one opening / closing lid 62 is sequentially opened to communicate with the odor collecting hood 7, and the other opening / closing lid 62 is closed. Therefore, even if the stirring device 3 moves, air containing odor does not leak out.

A suction device 63 is provided at one end of the deodorizing duct 61 and is connected to a dehumidifier 64. Then, the air dried through the dehumidifier 64 is passed through the chicken manure layer P from the bottom portion of the second treatment tank 2B, thereby deodorizing.

For this reason, a blower duct 65 is provided at the bottom of the second treatment tank 2B, and air containing odors sucked and dried from the first treatment tank 2A is discharged from the blower duct 65 to the second treatment tank. It is supplied to the poultry manure layer P accumulated in 2B. The poultry manure in the poultry manure layer P has already progressed to fermentation and has already been dried to a granular form, and contains actinomycetes and the like. Therefore, when the blown air passes through the poultry manure layer P, the actinomycetes or the like decompose the ammonia or the like to perform a deodorizing action and eliminate the odor.

In order to allow the stirring device 3 to pass through the semicircular portion formed at the end of the poultry manure processing tank 2, the direction of the stirring device 3 must be reversed. Therefore, in the illustrated embodiment, the direction changing portion 8 is provided at the end of the partition wall 22. Since the direction changing section 8 changes the direction around the rotation rail 81 as a rotation center, the column 83 is erected on the base 82 provided at the end of the poultry manure processing tank 2 so as to be located on the extension line of the partition wall 22. Along with the upper end of the base 82, a rotary shaft 84
A turntable 85 is rotatably provided via the.
That is, by rotatably supporting the rotary rail 81 via the turntable 85, when the agitating device 3 changes direction, only the outer drive wheel 34 provided in the agitating device 3 is driven and the inner drive is performed. The wheel 34 is retained on the rotary rail 81, and the direction of the rotation is changed around the rotary shaft 84 of the rotary rail 81.

Further, the direction change operation will be described.
When the stirring device 3 travels on the traveling rail 41 of the first treatment tank 2A together with the odor collecting hood 7 to reach the rotating rail 81, the rotation of the drive wheel 34 on the inside, that is, the rotating rail 81 is stopped. Then, in the stirrer 3, only the outer drive wheel 34 rotates, so that only the outer side travels along the traveling rail 41, and the turntable 85 rotates about the rotation shaft 84. Then, after rotating 180 degrees, the inner drive wheel 3
4 is restarted. Then, the stirrer 3 restarts straight ahead and advances along the second processing tank 2B. Then, at the other end as well, the direction is changed in the same manner and the process proceeds again and moves endlessly.

Next, the processing operation of the chicken manure processing apparatus 1 according to the present invention will be described. Fresh poultry manure, that is, moist poultry manure just collected from the poultry house, is put into the first treatment tank 2A from the poultry manure introduction section 23 formed at the end of the first treatment tank 2A, and the stirring device 3 is operated. The stirring device 3 may be operated at all times and charged at a time when the stirring device 3 is out of the chicken manure input unit 23.

The stirring device 3 advances at a predetermined low speed while rotating the first tilling claw 38a and the second tilling claw 38b to dig up the chicken manure and take in the air into the chicken manure. That is, the oxygen in the air is brought into contact with chicken droppings. The poultry manure that has obtained oxygen generates heat due to the action of aerobic bacteria, and the fermentation proceeds, and the fermentation process removes water. Further, at the time of stirring, the poultry manure is gradually pushed in the direction opposite to the advancing direction of the stirrer 3 (the white arrow in the figure) (the black arrow in the figure), and the poultry manure that has passed the time since the pouring is It is gradually transferred from the first processing tank 2A to the second processing tank 2B. In addition, if the air supply path 91 is embedded in the bottom of the first treatment tank 2A so that the outside air is introduced and forcedly blown, and the blower 92 is installed, the fermentation can be further efficiently performed. .

On the other hand, when stirring is performed by the stirring device 3, an ammonia odor is generated. The air containing the odor is collected in the deodorizing duct 61 by the ventilation fan 74 via the odor collecting hood 7. The collected air is guided by the suction device 63 through the deodorizing duct 61 to the air passage 65 provided at the bottom of the second processing tank 2B. The air is dried by a dehumidifier 64 provided near the suction device 63.

This dry but odorous air is passed from below the second treatment tank 2B through the substantially dry and granular chicken manure layer P. Then, the air deodorized by the actinomycetes contained in the chicken manure and having no ammonia odor escapes above the second treatment tank 2B. Therefore, odor is not scattered around. In addition, since it is not necessary to provide a soil tank for deodorization as in the conventional case, a site and equipment for forming the soil tank are not required, and the apparatus can be simplified and the cost can be reduced.

The chicken dung that has been agitated and supplied with air by the movement of the agitator 3 is fermented to evaporate the water content and is gradually transferred in the direction opposite to the advancing direction of the agitator 3. , The final stage of processing, that is, the second processing tank 2
When the chicken manure extraction unit 24 at the end of B is taken out, granular dried chicken manure can be obtained and can be utilized as an organic fertilizer. When poultry manure obtained by raising without using bedding is added, a pure organic fertilizer having a high commercial value and free from straw and the like can be obtained.

Although the present invention has been described above with reference to the illustrated embodiments, the present invention is not limited to the above-described embodiments and can be appropriately implemented without changing the configuration described in the claims. For example, although the drying process of chicken manure has been described, the present invention can be easily applied to not only chicken manure but also other animal manure such as pig manure.
