The blades 11 can be attached to the outer periphery of the stirring blade 2 at desired intervals such as 120 ° intervals and 90 ° intervals. Although the stirring blade 2 in the illustrated embodiment has a spiral shape, the stirring blade 2 may have another shape. For example, a disk, a rod, a pipe, etc.,
Can be mounted at intervals in the longitudinal direction. When the stirring blade 2 is a disk, a rod, a pipe, or the like, the compost cutting air jet port 3 can be opened at the tip thereof. The high-pressure air supplied from the air passage 4 is preferably ejected from the compost cutting air ejection port 3. When the stirring blade 2 is a disk, a rod, a pipe, or the like, the blade 5 can also be formed on the outer peripheral edge or tip thereof. The compost stirrer according to the present invention comprises
0 is moved by the moving mechanism 6 in the deposited compost 50. As the moving mechanism 6, for example, a driving mechanism of an existing hoist type overhead crane can be used, and another mechanism can be used. In the present invention, as shown in FIG. 6, a pair of guide rails 21 is provided in parallel on columns on both sides in the width direction (left and right) of the compost field, and a lateral moving rail 22 is erected between the pair of guide rails 21 to move laterally.

With this configuration, the compost stirrer 10 can reciprocate in the left-right direction of the compost site along the lateral moving rail 22, and the lateral moving rail 22 reciprocates along the guide rail 21, whereby the compost stirrer can be moved in the front-rear direction. To be able to move back and forth. As shown in FIG. 2, the compost stirrer 10 hangs a chain 18 on a sprocket 16 provided on the upper part of the rotary shaft 1 and a driving sprocket 17 of a rotary driver 7 using a motor. When the driving sprocket 17 is rotated by the rotation, the sprocket 16 of the rotating shaft 1 is rotated to rotate the rotating shaft 1. As shown in FIG. 1, a compressor 19 (FIG. 1) is connected to an air passage 4 (FIG. 3) in a rotating shaft 1 of a compost agitator 10 mounted on a cart 24, and high-pressure air is then supplied to the air passage 4. As supplied. In order to stir the compost using the compost stirrer of the present invention, the rotating shaft 1 is inserted into the compost 50 as shown in FIG. To rotate. At this time, the compressor 19
Supply high pressure air to the air passage 4 of the compost agitator 10 from
The air is jetted from the compost cutting air jet port 3 of the compost stirrer 10. The pressure of the high-pressure air is, for example, 40 kg / cm 2
Although the degree is suitable, it can be arbitrarily selected according to the type of the compost 50, the thickness of the compost 50, the fermentation state, and the like. The compost 50 is cut or loosened by the high-pressure air jetted from the compost cutting air jet port 3, and
Air is supplied into the compost 50, and the inside of the compost 50 becomes aerobic and fermented easily. At the same time, the compost 50 is cut or loosened by the blade 5 of the blade 11 attached to the stirring blade 2, so that the compost 50 that has solidified due to the weight of the compost 50 is loosened and air is easily mixed in. It becomes easier to ferment. Further, the stirring blade 2 has a spiral shape ,
Since the rotating shaft 1 is inserted into the compost and rotates,
By the rotation of the spiral stirring blade 2, the deposited compost 50 is sent upward from below and stirred, and the compost underneath easily comes into contact with the outside air and is easily fermented. When using the compost stirrer of the present invention, the compost 50 is stirred by the compost stirrer 10 as described above.
As shown in FIG. 7, the carriage 24 is laterally moved by the left and right moving mechanism 25 to move the compost stirrer 10 in the same direction (the left and right direction of the compost field), and the compost stirrer 10 moves in the longitudinal direction of the lateral movement rail 22. When the (lateral movement) is completed, the lateral movement rail 22 is moved along the guide rail by the longitudinal movement mechanism 23 by a desired distance in the longitudinal direction of the compost yard and stopped. The stopped carriage 24 is again moved to the left and right moving mechanism 2.
5, the compost agitator 10 is moved in the same direction along the lateral movement rail 22. By repeating the lateral movement and the back and forth movement, the compost stirrer 10 is moved within the compost to stir the entire compost. The route of the lateral movement and the back-and-forth movement of the compost agitator 10 may be a route other than the above. In short, any route may be used as long as the compost can be stirred in general. The moving speed of the compost stirrer is 30 ~ 50c per minute
The rotation speed of the compost stirrer is preferably about 20 rotations per minute for about m, but any other moving speed or rotation speed may be used. If air is supplied by the compost stirrer about once a week, air can be sufficiently supplied to the entire compost and fermentation can be sufficiently performed. However, this also refers to the type of compost, the stirring capacity of the compost stirrer, It can be arbitrarily selected depending on the amount of air jetted from the outlet 3 and the like. Further, the compost stirrer can be automatically operated for 24 hours by automatic control. In the case of using the compost stirring device of the present invention, not only the air is spouted from the compost cutting air jet port 3 but also the air is spouted from an air hole of a pipe arranged in a pit on a floor of a compost site. Can also. The compost stirring apparatus of the present invention not only cuts compost with a blade, but also blows high-pressure air supplied to an air passage from a compost cutting air jet port of a stirring blade and uses the air to generate high-pressure air. Can also cut or loosen the compost and supply the air to the compost, which has the following effects. (1) Mixing and loosening of compost is ensured. In addition, air is reliably supplied to the entire compost, and the compost is fermented efficiently. (2) The compost is cut by the high-pressure air blown from the compost cutting air outlet, and the stems of the plants in the compost are also cut. Therefore, these are hardly entangled with the stirring blade, and the friction between the compost and the stirring blade is reduced. The rotation of the compost stirrer is reduced and the compost stirrer can be rotated by a small-horsepower rotary drive (for example, a motor).
Inexpensive things in time. Further, no trouble occurs due to the entanglement of the compost with the stirring blade. (3) Even if the compost adheres to the stirring blade, it can be blown off with high-pressure air blown out from the compost cutting air outlet before cutting it with the blade, so even if the sharpness of the blade is reduced Cutting efficiency and stirring efficiency do not decrease. The compost agitator of the present invention is provided with a moving mechanism for moving the compost agitator and a rotary drive for rotating the rotating shaft of the compost agitator, so that the following effects are obtained in addition to the above-described effects of the compost agitator itself. effective. That is, by moving the compost while rotating the rotating shaft of the compost agitator by the moving mechanism, the entire compost can be stirred and air can be supplied to the entire compost, and the accumulated compost can be evenly distributed from top to bottom. Fermentation can be facilitated.
