Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composting device for composting accumulated excrement accumulated at a height approximately twice the diameter of the stirring blade.

Previously, this type of equipment was a mechanization of the ancient method of composting, and was a conveyor type with many packets attached, so the mixing of accumulated waste and air was not sufficient, and therefore it was not possible to effectively decompose organic matter, i.e. No corrosion was performed.

Furthermore, when the water content limited by the water content of excrement exceeds 70%, there is a drawback that organic matter cannot be decomposed in a short period of time due to the physical properties of the electrolyzed manure.

An object of the present invention is to provide a composting device for accumulated excrement that can eliminate such drawbacks.

Next, the structure and operation of the present invention will be explained with reference to embodiments of the drawings.

A trolley 3 is mounted on a rail 1 so as to be able to run via wheels 2,
For example, a hydraulic motor 4 is mounted on this trolley 3, and the power is transmitted to the wheels to make it self-transporting.
The stirring blade 6 is mounted on an axis, and a second stirring blade 7 that rotates backward is mounted on a shaft slightly behind the first stirring blade 6, and the first and second stirring blades are mounted on the rear side of the second stirring blade 7. A third stirring blade 8 that rotates backward at high speed is mounted between the shafts 7 and 7.

A motor 9 fixedly mounted on the frame 5 is directly connected to the end of each stirring blade 678 with respective rotation directions and rotation speeds set.

The first, second, and third stirring blades 678 are a large number of discontinuous blades 11 fixed to the rotating shaft 10.

Note that this motor 9 may be connected using gears or the like.

Further, a plurality of third stirring blades 8 may be mounted in stages.

Thus, the accumulated excrement accumulated below the rail 1 is sufficiently agitated by driving the hydraulic motor 4 and the motor 9, and the organic matter is decomposed in a short period of time.

That is, since the first and second stirring blades 6 and 7 are provided above and below, the part above the center of the accumulated excrement is the first stirring blade.
The mixture is sufficiently stirred by the stirring blade 6 and sent to the rear, and the portion below the center is optically stirred by the second stirring blade 7 and sent to the rear, but the first stirring blade 6 rotates forward and the second stirring blade 7 rotates. Because of the backward rotation, the accumulated excrement is stirred and then divided into smaller pieces from the center of the first and second stirring blades 6 and 7, and then transferred to the third stirring blade.
This is sent to the stirring blade 8.

This third stirring blade 8 is located between the first and second stirring blades 6 and 7, and the excrement sent by the first and second stirring blades 6 and 7 is scattered backward and forward. It is about the same height as (this is what accumulates).

Therefore, the excrement that is scattered and deposited on the fog by the third stirring blade 8 is removed by the truck 3 at a speed of 0.5 m/min to 1.8 m/min by the power of the hydraulic motor 4.
*Since it moves backwards at high speed, it is stirred repeatedly over and over again.

Therefore, the accumulated excrement is sufficiently mixed with air and stirred, and it becomes possible to convert it into organic fertilizer regardless of the excessive moisture content of the accumulated excrement.

Incidentally, to describe the main functions of the first, second, and third stirring blades 678, the first stirring blade 6 performs bacterial cell mixing, the second stirring blade 7 performs temperature mixing, and the third stirring blade 8 performs stacking and air agitation. Become.

Moreover, it is even more effective if there are a plurality of third stirring blades 8.

Furthermore, experimental results using the apparatus of the present invention revealed the following excellent effects.

In addition, in the above experiment, each rice field was fed once using a stirrer.

In addition, when composting excrement accumulated at a height about twice the diameter of the stirring blade, conventionally, the upper and lower two stages of stirring blades were rotated in the same direction, that is, backward, as disclosed in Japanese Patent Application Laid-Open No. 54-54877. Therefore, the excrement that is about to be scattered backwards by the lower stirring blades is obstructed and prevented from rotating by the upper stirring blades, so the stirring effect becomes low and aerobic fermentation cannot be expected.

However, in the present invention, the speed range is 0.5 m/min to 1.8 m/min.
A first stirring blade 6 for mixing bacteria that rotates forward is mounted on the upper front side of the trolley frame 5 that moves at a speed of m in. A rotating second stirring blade 7 for temperature mixing is mounted on an axis, and a third stirring blade for stacking and air stirring that rotates backward at high speed is mounted diagonally rearwardly above the second stirring blade 7, that is, between the first and second stirring blades 6 and 7. The stirring blades 8 are mounted on the axis in stages, so that the entire accumulated excrement is collected and stirred in the middle part by both the first and second stirring blades 6. ，
7, the excrement is sent backward while being fragmented, and the fragmented excrement is further dispersed in the form of mist by the third stirring blade 8, which rotates backward at high speed, so that the entire excrement is deposited high and is reliably fragmented. Since it is further dispersed into the fog ash, it is effectively stirred and excellent aerobic fermentation can be obtained.
