Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stirrer used for fermenting livestock manure for composting, and more particularly to a small fermentation stirrer which can be installed in a small-scale compost house.

[0002]

2. Description of the Related Art In recent years, the problem of livestock excreta disposal has become a serious problem 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 manure to perform fermentation treatment and composting. Compost fermentation is a process in which fat, fiber, protein, and other organic substances, which are the main components of manure, are microbial-degraded, and high-molecular-weight substances are converted to low-molecular-weight organic fertilizers. Specifically, a composting facility is used in which microorganisms are introduced into animal manure in a compost house for storing animal manure and the mixture is automatically stirred by a stirrer and fermented.

[0003]

However, the conventional composting facilities are large-scale and the fermentation agitation equipment used there is also large. Although the stirring operation is performed by using a heavy machine such as a shovel car, etc., in reality, a small-sized fermentation stirrer capable of automating the stirring operation even in such a small-scale compost building has been desired. The present invention has been made in view of the above-described problems of the related art, and has an object to provide a fermentation stirring device for livestock manure that is suitable for use in a small-scale compost bar that fermentates livestock manure. It is.

[0004]

For this reason, a fermentation and agitation processing apparatus for livestock dung of the present invention is installed on an upper open surface of a tank for storing livestock dung, and is capable of reciprocating back and forth. And a rotary stirrer that is reciprocally movable left and right on the gantry.

In a second aspect of the present invention, the rotary stirrer is an endless crawler having a plurality of blades.

Further, a third feature of the apparatus for fermenting and stirring livestock manure according to the second aspect is that a scooping plate is provided on the blade plate inclining in the direction of rotation of the blade plate.

In a fourth aspect of the present invention, the rotating stirrer is inclined and moves in the traveling direction. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1 and FIG. 2, P is a concrete compost house for fermenting animal manure such as cows and pigs and composting it. Raw feces fermenter P1, with W2, W3, W4,
It is divided into three storage tanks, a fermentation compost (product) storage place P2 and a raw feces storage place P3. The fermentation stirrer A is installed on the upper surface of the raw feces fermenter P1,
1. A gantry 5 reciprocally movable back and forth on rails R1 and R2 attached to the upper end of the gantry 1. A rotary stirrer suspended from the gantry 5 and reciprocable left and right on the gantry 5 And 1.

As shown in FIGS. 3 to 5, the gantry 5 includes four wheels 12 provided at the front, rear, left and right ends thereof, four gear boxes 8 and three connecting shafts 7a, 7b,
7c so as to be able to move forward and backward on 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. Have been. In addition, a pair of angle rails 5b are provided in front of and behind the gantry 5 in parallel with each other. On this angle rail 5b, a V-shaped wheel 10 fitted to a moving carriage 5a described later is fitted. It is made to run.

The gantry 5 is provided with a movable trolley 5a on which the rotary agitator 1 is hung down and on which two motors are mounted. One motor on the movable carriage 5a is a reciprocating motor 3 for reciprocally moving the movable carriage left and right on the gantry, and is connected to the rotating shaft of the wheel 10 via a drive chain 3a. The other motor is a stirring motor 6 for rotating the rotary stirrer 1 forward and backward in the vertical 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 attached so as to sandwich the moving rails R1 and R2 from above and below.

The rotary stirrer 1 has a pair of sprockets (chain wheels) 11 arranged at upper and lower ends thereof, and a stirring chain 2 is stretched between the sprockets 11 to form an endless track. The stirrer is connected to a stirring motor 6 mounted on the top 5 via a drive chain 6a so as to rotate in both forward and reverse directions. A number of vanes 4 are attached to the stirring chain 2 at predetermined intervals in a crawler belt shape. In addition, a pair of scooping plates 4 each of which is inclined in the up-down direction is provided at a tip end of each of the blades 4.
a is integrally attached so that a has a substantially Y-shaped cross section. With the scooping plate 4a, even when the rotary stirring body 1 rotates in either the forward or reverse direction, the animal dung can be scooped and stirred.

As shown in FIG. 4, the rotary stirrer 1 is entirely inclined in the traveling direction. This inclination angle is inclined at a predetermined angle with respect to the longitudinal direction of the rotary stirrer 1, and the inclination angle is about 10 degrees to 30 degrees,
Preferably, it is set to about 15 degrees. Thus, the dung can be reliably scraped up in combination with the above-described operation of the scooping plate 4a of the stirring blade plate 4, and the stirring effect is amplified.

The rotating stirrer 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 rotary stirrer 1 moves in a zigzag manner while rotating in the raw feces fermenter P1, and can stir the stored livestock dung and the introduced microorganisms uniformly. Specifically, when the rotary stirrer 1 moves to the right on the gantry, it rotates counterclockwise. Reciprocate. In each tank of the compost house P, a blower 13 having a built-in heat heater is installed. In order to promote fermentation, air is blown from the floor by a blower to supply air. In addition, when the moisture content of feces is high, fermented feces,
The water content is adjusted to about 60% to 70% with sawdust or the like. At this time, 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.

[0016]

As described above, according to the present invention, there is an excellent effect that the labor for composting can be reduced in a small-scale composting facility for fermenting animal manure.
