Description

  The present invention relates to a stirrer used for fermenting livestock manure and composting, and particularly to a small fermentation stirrer which can be installed in a small-scale compost house.

  In recent years, the problem of livestock excreta disposal has become a serious issue for livestock farmers, in conjunction with the revision of the regulations (prohibition of unloading, etc.). Therefore, conventionally, a method has been adopted in which microorganisms are added to livestock dung, fermented, and composted. Compost fermentation treatment is a process in which fat, fiber, protein, and other organic substances, which are the main components of manure, are microbial-degraded, and the high-molecular-weight substances are converted to low-molecular-weight substances to transform them into organic fertilizers with uniform components. Specifically, a composting facility is used in which microorganisms are put into a compost house for storing livestock dung and the mixture is automatically stirred by a stirrer and fermented.

However, conventional composting facilities are large-scale and the stirrer used there is also large, so in small-scale compost houses owned by small and medium-sized livestock farmers, heavy machinery such as excavators are used. The actual situation is that the agitation work is performed, and there has been a long-felt need for a small-sized fermentation agitation apparatus capable of automating the agitation work even in such a small-scale compost building and reducing the labor for compost treatment. Therefore, the applicant of the present application is mounted on an upper open surface of a tank for storing animal droppings, and a rack that is reciprocally movable back and forth, and is provided hanging from the rack, and is capable of reciprocating left and right on the rack. In a livestock manure fermentation stirring device, the rotation stirring member is formed by an infinite crawler belt having a plurality of blades, and the blades are inclined toward the rotation direction of the blades. A fermentation and stirring device for livestock manure has been proposed in which a scooping plate is provided and the rotary stirrer is inclined and moves in the direction of travel (Patent Document 1).
JP-A-2002-191954

  In the present invention, the rotary stirrer is formed by a screw stirrer, and a blower device capable of blowing hot air for promoting fermentation of animal dung is provided from the tip of the screw stirrer. It is an object of the present invention to provide a more suitable animal dung fermentation and stirring device in a compost house.

  For this reason, the livestock dung fermentation stirring device of the present invention is installed on the upper open surface of the tank for storing livestock dung, and is provided so as to be able to reciprocate back and forth. The first feature is that a screw stirrer that can be reciprocated and a blower device that can blow air for promoting fermentation of animal dung from the tip of the screw stirrer are provided.

  A second feature of the animal dung fermentation stirring device according to the first aspect is that the blower device is a blower device with a heater, and the air for promoting the fermentation of the animal dung is warm air.

  ADVANTAGE OF THE INVENTION The fermentation stirring apparatus of the animal dung of this invention has the outstanding effect that the labor of a compost processing can be reduced in a small-scale composting room which fermented an animal dung.

  Hereinafter, the best mode for carrying out the present invention will be described based on an embodiment shown in the drawings. FIG. 1 is a plan view showing a state in which the fermentation stirrer according to the present invention is attached to a compost house, FIG. 2 is a front view of FIG. 1, FIG. 3 is a plan view of the fermentation stirrer according to the present invention, and FIG. FIG. 5 is a front view of the stirring device, FIG. 5 is a side view of the fermentation stirring device, and FIG.

  In FIG. 1 and FIG. 2, P is a concrete compost house for fermenting animal dung such as cows and pigs for composting. The top and front surfaces are open and concrete walls W1, W2, W3, and W4 are provided. Thus, it is divided into three storage tanks: a raw manure fermenter P1, a fermentation compost (product) storage P2, and a raw dung storage P3. The fermentation stirrer A is installed on the upper surface of the raw feces fermenter P1, and has a gantry 5 that can reciprocate back and forth on rails R1 and R2 attached to the upper end of the raw stool fermenter P1, 5 and a screw agitator 1 which is reciprocally movable left and right on the gantry 5.

  As shown in FIGS. 3 to 5, the gantry 5 includes four wheels 12 provided at front, rear, left and right ends thereof, four gear boxes 8 and three successive shafts 7 a, 7 b, 7 c. Connected to the forward / backward motor 7 through the moving rails R1 and R2 attached to the upper ends of the left and right walls W1 and W2 of the raw feces fermenter P1 along the front-rear direction. I have. A pair of angle rails 5b are provided in parallel before and after the gantry 5, and a V-shaped wheel 10 with a fitting cross section attached to a moving carriage 5a described later is fitted on the angle rails 5b. It is made to run in.

  A screw stirrer 1 is attached to the gantry 5 via a motor 6 and a gear box 6a, and a movable trolley 5a on which a motor and a blower device 2 with a heater for facilitating animal dung fermentation are installed on the upper surface is provided. I have. The motor on the movable trolley 5a is a reciprocating motor 3 for reciprocating the movable trolley right and left on the gantry, and is connected to a rotating shaft of the wheel 10 via a drive chain 3a. The motor 6 is a stirring motor provided via a gear box 6a for rotating the screw stirring body 1 in the opposite direction. Reference numeral 9 denotes an auxiliary wheel disposed below the angle rail 5b to prevent the angle rail 5b from falling off. The auxiliary wheel 9 is attached to the wheel 10 and the auxiliary wheel 9 so as to sandwich the angle rail 5b from above and below. In this case, the relationship between the moving rails R1 and R2 and the wheels 12 has the same configuration, and the wheels 12 and the auxiliary wheels 9 are mounted so as to sandwich the moving rails R1 and R2 from above and below.

  Further, as shown in FIG. 4, the screw stirring body 1 is composed of a biaxial screw, is connected to the motor 6 via a gear box 6a, rotates in the opposite direction, and stirs the animal waste effectively. Can be. In addition, air is blown from the blower device 2 with a heater for facilitating animal dung fermentation through the pipe 4 to the shaft portion 13 of the screw stirring body 1, and hot air optimal for fermentation is blown from the tip of the screw stirring body 1. The fermentation can be promoted simultaneously with stirring.

  Further, the screw agitator 1 shown in FIG. 5 is entirely inclined in the traveling direction. This inclination angle is inclined at a predetermined angle with respect to the axis of the screw agitator, and this angle is set to about 10 to 30 degrees, preferably about 15 degrees. Thereby, the livestock dung can be surely stirred in combination with the above-mentioned stirring action of the screw stirring body 1, and the stirring effect is amplified.

  The screw agitator 1 reciprocates left and right on the gantry 5 while the gantry 5 reciprocates on the raw feces fermenter P1 back and forth. Therefore, as shown in FIG. 6, the screw agitator 1 moves in the raw feces fermenter P1 in a tooth shape, and can uniformly stir the stored livestock dung and the introduced microorganisms. In each tank of the compost house P, a blower 11 having a built-in heat heater is installed, and in order to further promote fermentation, air is blown from the floor surface by a blower to supply air. When the water content of feces is high, the water content is adjusted to about 60% to 70% by fermented feces, sawdust and the like. Thereafter, it is more preferable to stir while simultaneously spraying a chemical solution for removing fermentation odor. Since the compost after the fermentation treatment has uniform particles, it has no feeling of fouling, is easy to handle, and can be recycled as a good organic fertilizer.

It is a top view showing the state where the fermentation stirrer concerning the present invention was attached to the compost house. It is a front view of FIG. FIG. 3 is a plan view showing the fermentation stirring device according to the present invention. It is a front view of a fermentation stirring apparatus. It is a side view of a fermentation stirring device. It is explanatory drawing which shows the movement locus of a screw stirring body.
