DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for aerating and stirring manure fluid from livestock and humans.

[0002]

2. Description of the Related Art Conventionally, a submersible pump type aerator is known. However, such a device requires that the equipment installed in the manure fluid be electrically connected to a power source outside the tank, so that the cover of the lead wire wired in the manure fluid is easily corroded by the components of the manure fluid. In addition, there is a problem that electric leakage easily occurs due to this problem.

[0003] In order to solve such a problem, the present applicant first penetrates a rotary shaft through an intake pipe vertically installed in a manure liquid tank, and sets an intake wing near a lower end portion of the rotary shaft. A configuration in which a stirring blade is attached to the lower end of the rotating shaft, a fan case capable of absorbing and draining liquid is attached to the lower end of the intake pipe, and the stirring blade is disposed in the fan case. And an agitating device (see Japanese Utility Model Publication No. Sho 63-50278) and a stirring blade disposed inside the manure liquid tank, and a rotating shaft of the stirring blade is connected to a motor outside the manure liquid tank. The gears on the air pump side are meshed with the gears on the stirring blade side mounted on the rotating disk, the gears on the air pump side are mounted on the rotating shaft of the rotating disk, and the air pump is connected to the eccentric position of the rotating disk. Manure fluid aeration with a diffuser tube in the liquid tank拌 devised apparatus (see actual fair 1-18234 JP). However, these devices have complained that the structure is complicated and expensive.

Therefore, the present applicant has further improved the structure of the apparatus by simplifying the structure, that is, by suspending the rotating shaft in the excrement tank and guiding the air diffuser, so as to face the opening of the distal end of the air diffuser. A fan is attached to a rotating shaft, and while the manure is being stirred by rotating the fan, a device for inhaling and aerating air from the air diffuser by rotating the fan (refer to Japanese Patent Application No. 6-240609). Invented. However, this device also has a dissatisfaction that the processing capacity for stirring and aerating the excrement is insufficient.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention solves the above-mentioned problems of the conventional apparatus, that is, there is no need to worry about corrosion of the lead wire cover and leakage due to the corrosion, and to reduce the structure. It is an object of the present invention to provide a novel manure fluid aeration / stirring apparatus which can be provided simply and at low cost, and which can enhance the processing capacity of aeration / stirring of manure fluid.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention. First, a manure fluid introduction pipe 2 is connected to the manure fluid tank 1 from a livestock barn (not shown), and the top of the manure fluid tank 1 is covered with a lid 3, and a case 4 is fixed on the lid 3. . The case 4 has an inclined surface 5 with a part of the bottom recessed downward, and the inclined surface 5 penetrates through the lid 3 and slightly protrudes below the lid 3. The upper end of a pipe-shaped shaft cover 6 is joined to the inclined surface 5, and a rotary shaft 7 is inserted into the shaft cover 6. The rotating shaft 7 and the shaft cover 6 extend into the feces liquid tank 1 in a posture inclined at an angle of about 45 ° with respect to the vertical direction and the horizontal direction, respectively. Further, a stirring and suctioning rotary blade 8 is attached to a lower end portion of the rotary shaft 7. A diffuser 9 is provided on both sides of the shaft cover 6.
The air diffusion tube 9 has an upper end opening exposed above the lid 3 to form an air inlet 10, and a lower end opening immersed in the feces fluid 11 to exhaust the air.
It is 2. The rotating blades 8 for stirring and suction are located so as to face the exhaust port 12 of the air diffuser 9. A cylindrical fan case 13 having both ends opened is provided around the stirring / intake rotary blade 8 and the exhaust port 12 of the diffuser tube 9. The lower end of the shaft cover 6 is connected to a suspension rod 14 for support. A transmission mechanism 15 using a pulley and a deflection mechanism 16 using a universal joint are provided inside the case 4, and the upper end of the rotating shaft 7 to which the rotating blades 8 for stirring and suction are mounted is connected to a deflection mechanism. 16. In addition,
The transmission mechanism 15 and the deflection mechanism 16 are not limited to the pulleys and universal joints described above. One end of the main shaft 17 of the transmission mechanism 15 projects outside the case 4 and can be connected to a drive shaft 18 of an external drive means such as an engine of a tractor. It is to be noted that a deflectable connection attachment 20 to which a universal joint 19 is attached is provided, and the connection attachment 20 is interposed between the main shaft 17 of the transmission mechanism 15 and the drive shaft 18 of the external drive means. Connection is possible even if the position of the external drive means changes.

When the rotating shaft 7 is rotated by an external driving means such as an engine of a tractor, the rotating blades 8 for agitation and suction also rotate, so that the feces liquid 1 enters the fan case 13 from one end opening.
1 is sucked and agitated, and at the same time, by the rotation of the agitating and suctioning rotary blades 8, the excrement 11 stirred by the air sucked through the air diffuser 9 is aerated. The agitated and aerated feces fluid 11 flows out from the other end opening of the fan case 13. In this way, the manure fluid 11 in the manure fluid tank 1 circulates so as to pass through the fan case 13 and
Is stirred and aerated. The excrement 11 rapidly rots and matures by stirring and aeration, and can be used as an organic fertilizer useful for grass and field crops.

[0010]

The present invention is as described above. A beneficial organic fertilizer can be obtained by rapidly decay aging by aeration and agitation while circulating the manure fluid 11, and furthermore, lead is contained in the manure fluid. Since the wires are not wired at all, there is no fear of causing corrosion of the lead wire cover by the excrement 11 and leakage due to the corrosion, and there is an effect that the wires can be used with confidence. In addition, since the rotating blade 8 for stirring the feces and liquid also serves as the rotating blade for intake, it is necessary to particularly provide an air pump for sending air to the diffuser tube 9 and an intake blade for sucking air into the diffuser tube. Therefore, there is an advantage that the structure of the entire apparatus can be simplified. In particular, in the present invention, since the rotating shaft 7 to which the stirring and intake rotating blades 8 are attached is inclined so as to have an angle with respect to the vertical direction and the horizontal direction, the manure flowed by the rotating blades 8 The liquid 11 has a velocity component not only in the vertical direction but also in the horizontal direction. That is, the feces fluid 11 is supplied to the rotating blade 8
As a result, the fluid is forced to flow in the lateral direction. In the case of the above-described conventional apparatus in which the rotating shaft with the rotating blades is vertically installed, the feather fluid flows mainly in the vertical direction by the rotating blades, and is slightly laterally moved when it hits the bottom of the manure fluid tank. Since the flow only changes in the direction, the circulating flow of the manure was only locally generated without reaching the entire inside of the manure tank, but as in the present invention, the rotating shaft 7 was tilted to remove the manure as described above. If the forcible fluid is forced to flow in the lateral direction as well, the circulation of the manure fluid 11 in the manure fluid tank 1 becomes active and the area thereof is expanded. Therefore, a large amount of feces and urine in a wide range passes through the fan case 13, which has an effect of increasing the processing capacity of stirring and aeration. Further, a rotating shaft 7 of 攪拌兼intake rotating blade 8, since this and orientation is provided with a diverting means and transmission means for connecting the drive shaft 18 of different external driving means, driving the engine, such as a tractor The convenience that it can be used as a means is obtained.
