So that they are in contact with each other. Then, if the drive motor 15 is driven in this state, the support body 8 rotates at a predetermined speed together with the guide rail 13, and the stirring blades 9, 10 revolving in the stirring tank 4 as the support body 8 rotates. Each is configured to rotate at a predetermined speed.

  As described above, the stirring blades 9 and 10, the scraper blade 11, the support portion 8 that supports them, and the like are provided integrally with the support frame 5, and are formed into a unit, and if the support frame 5 is removed from the machine base 3, the stirring blades 9, 10 and the scraper blades 11, the support portion 8 and the like can be excluded from the upper part of the stirring tank 4 together. Reference numeral 18 denotes a handle 18 for an operator to hold when the support frame 5 is detached from the machine base 3.

  The bottom of the agitation tank 4 is provided with a discharge gate 19 for discharging material, and a discharge chute 20 is provided below the gate. A support member 21 for supporting the stirring tank 4 is fixed to the back surface of the stirring tank 4, while an elevating member 22 that can slide up and down along the vertical frame 3 a is attached to the vertical frame 3 a of the machine base 3. A horizontal member 23 is installed on the pair of elevating members 22, and both ends of the support member 21 are detachably fixed to the horizontal member 23 with bolts and nuts 24. In addition, as shown in the figure, the machine base 3 below the stirring tank 4 is provided with an open space 25 having a sufficient size that allows the stirring tank 4 to pass therethrough.

  Therefore, by moving the elevating member 22 up and down while the support member 21 below the stirring tank 4 is fixed to the horizontal member 23, the height of the stirring tank 4 is adjusted from the solid line position to the two-dot chain line position in the figure. And the upper end edge of the stirring vessel 4 is at least lower than the lower end portions of the stirring blades 9 and 10 and the scraper blade 11 when pulled down to the two-dot chain line position. If 24 is removed and the fixing of the supporting member 21 and the horizontal member 23 at the lower part of the stirring tank 4 is released, the stirring tank 4 can be easily pulled out in the horizontal direction without interference with the stirring blades 9 and 10.

  One or more stirring tanks (not shown) having the same structure as the stirring tank 4 are prepared.

  And when adjusting the stucco of a desired color using the stirring apparatus 1 of the said structure in a construction site etc., first, the stucco raw material, water, and a pigment are thrown into the stirring tank 4 on the machine base 3 predetermined amount at a time. After that, the drive motor 15 is driven to rotate the support 8 at a predetermined speed. When the support 8 rotates, the stirring blades 9 and 10 and the scraper blade 11 revolve in the stirring tank 4 and each stirring blade 9 wound by the fixed gear 7c of the fixed shaft 7 and the chain 12, The ten driven gears 9c, 10c are rotated in conjunction with each other, and the respective stirring blades 9, 10 rotate at a predetermined speed. Thus, the various materials in the stirring tank 4 are kneaded by the stirring blade 9 that rotates relatively slowly while being sheared by the stirring blade 10 that rotates at a high speed, and the various materials in the stirring tank 4 do not leave a lump or the like. Stirring and kneading treatment is suitably performed without unevenness, and a stucco exhibiting a desired color is prepared.

  Moreover, when it becomes necessary to adjust the plaster of a color different from this, after the discharge gate 19 is opened and the plaster that has been adjusted first is discharged, the elevating member 22 is lowered and the stirring tank 4 is operated. Is pulled down from the solid line position to the two-dot chain line position which is the open space 25. Then, the bolts and nuts 24 fixing the support member 21 below the stirring tank 4 and the horizontal member 23 at the position of the two-dot chain line are released, and the stirring tank 4 is slid in the horizontal direction to be opened. Pull out to the side of the machine base 3 through the space 25. At this time, the upper end edge of the stirring tank 4 is configured to be at a position lower than at least the lower ends of the stirring blades 9 and 10 and the scraper blade 11, and the stirring tank 4 interferes with the stirring blades 9 and 10. It can be pulled out easily without any problems.

  Thus, after washing only the stirring blades 9 and 10 and the scraper blade 11, a stirring tank (not shown) prepared separately is installed in the lower part of the machine base 3 in place of the stirring tank 4 removed in the above procedure. It is pushed into the open space 25 and fastened and fixed to the horizontal member 23 with bolts and nuts 24. In this state, the elevating member 22 is lifted to raise the stirring tank from the two-dot chain line position to the solid line position and perform a fixing operation. Also at this time, as described above, the agitation tank has no possibility of interfering with the agitation blades 9, 10 and the like. In this way, the stucco raw material, water, and a pigment of another color are put into the stirred tank that has been replaced, and the stucco exhibiting a desired color is prepared by stirring and kneading as described above.

Thus, the stirring tank 4 is not integrated with the stirring blades 9 and 10 and its driving mechanism, and is separated, and the stirring tank 4 is detachable from the machine base 3 and is a lower level machine of the stirring tank 4. Since the table 3 is provided with an open space 25 that is wide enough to allow the passage of the agitation tank 4, the entire agitation tank 4 can be replaced while avoiding interference with the agitation blades 9, 10 and their drive mechanisms. Even if it becomes necessary to frequently change the color, type, or properties of the stucco to be adjusted at the construction site, the replacement work for each stirring tank 4 and only the stirring blades 9 and 10 and the scraper blade 11 Only a simple cleaning process is required and it is very troublesome. There it is possible to perform efficiently adjustment work the cleaning process of the agitating tank 4 as required. In addition, by changing the agitation tank 4 according to color, type, and property, mixing of different colors and different components can be suppressed as much as possible, and an improvement in the quality of the plaster to be adjusted can be expected. Furthermore, the amount of waste liquid generated during the cleaning process can be suppressed as much as possible, which is preferable in terms of environment.

  Further, in replacing the stirring tank 4, the support frame 5 may be detached from the machine base 3 as shown in FIGS.
