However, since the stirring blade of this stirring / mixing device has a shape like a rotary hook, the particles of the culture soil and the like are often too finely divided. When seedlings are planted using culture soil etc., the drainage tends to be too good and the water retention capacity tends to decline, and moreover, the air flow in the culture soil etc. becomes poor and oxygen is difficult to spread. was there. Moreover, since the blade portion is long and slender, only a part of the culture soil in the mixing tank can be fed out when the blade rotates, so that sufficient stirring cannot be performed and unevenness is likely to occur.

Therefore, the present invention has been made in view of the above problems, and an object thereof is to prevent the fibrous material such as culture soil from being unnecessarily broken and to keep it to an appropriate size. An object of the present invention is to provide a stirring / mixing device capable of performing stirring / mixing in this manner.

In this case, a slight gap 17 is formed so as not to block the opening 6a.
The conical discharge body 8 is fixed so as to form

The support mechanism 3 forms a support frame 18 by appropriately combining steel materials having a C-shaped cross section so that the support mechanism 3 can have a space large enough to mount the rotary cylinder 2.
The four support rollers 19 are rotatably fixed on the support frame 18. The support roller 19 is
Each of them is located at substantially four corners of the support frame 18, and fits and abuts between the flange portions of the guide portions 7a and 7c from the left and right on the lower side of the rotary cylinder 2.

The drive mechanism 4 comprises a sprocket 21 fixed on the same axis of the drive motor 20 and a sprocket projection 7d formed on the guide portion 7b, and a chain 22 laid over the sprocket projection 7d. Is transmitted through the chain 22 to rotate the rotary cylinder 2.

The stirring and mixing apparatus 1 of the present invention has the above-mentioned structure and is used or operated as follows.

The stirring and mixing apparatus 1 is used with a crushing apparatus installed on the front side via a belt conveyor and a soil filling apparatus installed on the back side via a discharge tank 50 and a belt conveyor.
The crushing device is for crushing culture soil or the like as appropriate, and the crushed culture soil or the like is conveyed by a belt conveyor and poured into the inside of the rotary cylinder 2 through the opening 5a on the front side.

After pouring several kinds of culture soil and the like by a belt conveyor, the stirring and mixing device 1 carries out a stirring and mixing work described later, and the culture soil and the like thereafter are discharged from the opening surface 6a and poured into the discharge tank 50. Since the discharge tank 50 is provided with a screw auger inside, the culture soil and the like discharged from the opening surface 6a is sent to the belt conveyor while being again stirred and mixed. When the belt conveyor conveys the culture soil or the like to the soil filling device and flows it into the device, the soil filling device performs the soil filling work and the work of filling the culture soil or the like in appropriate amounts.

The stirring and mixing operation by the stirring and mixing apparatus 1 is performed as follows. By turning on a power switch (not shown), the power of the drive motor 20 of the drive mechanism 4 is transmitted to the rotary cylinder 2 via the chain 22, and the rotary cylinder 2 rotates. In this case, the rotating cylinder 2 rotates about the rotating shaft L while the lower portion is supported by the supporting roller 19, and the direction of rotation can be changed at any time by switching the switch.

When stirring and mixing culture soil, etc., the rotating cylinder 2
Is rotated in the direction A (counterclockwise) shown. Then
The culture soil or the like poured into the inside is stirred and mixed by the stirring blade 10 and the stirring blade 12. At this time, since the stirring blade 10 is mainly formed of a metal plate, it does not apply a large compressive force to the culture soil or the like, and the culture soil or the like can be stirred while being fed over the entire curved surface. it can. Moreover, since both the stirring blades 10 and 12 are fixed at equal intervals along the direction of the rotation axis L of the rotary cylinder 2 to form the stirring rows 11 and 13, respectively, the culture soil in the rotary cylinder 2 is It is possible to perform stirring and mixing in a state where the desired size is maintained uniformly and evenly,
The fibers contained in the culture soil and the like can be stirred and mixed while maintaining an appropriate size without rupturing more than necessary.

Further, since both the stirring blades 10 and 12 are curved, the action of wrapping and holding the culture soil on the curved surface can be enhanced, whereby the transporting action of the culture soil or the like is simply a flat plate. It can be higher than that obtained by stirring with. Further, since the angle of fixing is appropriately tilted when viewed from the rotation axis L, the stirring efficiency can be improved as compared with the case where the angle is fixed in parallel with the rotation axis L. Further, the stirring blade 12 has the mounting legs 12a, 12a.
Since the culture soil and the like can pass through the space between the mounting legs 12a, 12a because they are fixed by using the culture soil and the like, the culture soil and the like sent out by the stirring blade 12 and the culture soil and the like passing through the space. It is possible to generate a low-passing state and further improve the stirring efficiency.

Then, after rotating the rotating cylinder 2 for a predetermined time to perform stirring and mixing, this time, the rotating cylinder 2 is moved in the opposite direction B.
Rotate (clockwise). Then, the stirring blades 10, 1
The culture soil and the like mixed and stirred by 2 are sent to the back side while being sent out by the discharge blade 10 and are conveyed upward while being sent out by the discharge blade 14. Then, when the discharge blade 14 on which the culture soil or the like is placed passes near the uppermost portion, the culture soil or the like slides down from the discharge blade 14 and drops downward.
In this case, since the conical discharge body 8 is fixedly attached to the closed surface 6 on the back side, the dropped culture soil or the like travels along the surface of the conical portion 9 to reach the tip portion 9a, and from the gap 17 of the opening portion 6a. It is discharged to the outside. In this way, the culture soil and the like after stirring and mixing are sent to the discharge tank 50.
