The shaft 26 is vertically rotatably supported by bearings 27, 27. The shaft 26 is connected to a rotating shaft of a variable speed motor (not shown) through an endless belt 28, The driving causes the rotary drum 21 to rotate vertically at a variable speed. From the small-diameter side opening of the rotary drum 21, the tip of a raw material powder supply device 29 for transporting the raw material powder quantitatively cut by a quantitative supply device (not shown) to a central portion in the rotary drum 21, and a binder tank (not shown) The front ends of the binder supply devices 31 for transporting the binder inside the drum to the central portion inside the rotary drum 21 are inserted respectively.

[0006] Outside the lid member 22 of the rotary drum 21, guide rods 31, 31, which form a pair in the front and rear direction, are horizontally supported by a gantry 32. Guide holders 33, 33 are slidably inserted into the guide rods 31, 31, respectively.
Suspends one motor support bracket 35 via arms 34, 34. Each guide holder 33 can be fixed at an arbitrary position on the guide rod 31 by a set screw 36. A variable speed motor 37 is attached to the bracket 35 so as to face the rotary drum 21 and to match the rotation axis of its output shaft with that of the rotary drum 21. On the front surface of the motor 37, a stepped cylindrical bracket 38 is mounted concentrically with the output shaft of the motor 37, and a small-diameter end portion of the bracket 38 is formed in the center of the lid member 22. It can penetrate through the opening and protrude into the rotary drum 21. Reference numeral 39 denotes a rotary shaft which is loosely inserted into the stepped cylindrical bracket 38, has a base end connected to the output shaft of the motor 37, and has a distal end protruding from a distal end opening of the bracket 38. A plurality of crushing blades 40 are attached to the section, and the driving of the motor 37 causes the crushing blades 40 to rotate vertically at a variable speed. Reference numeral 41 denotes a scraper which is attached to the small-diameter portion of the stepped cylindrical bracket 38 and scrapes off the deposits on the inner wall of the rotary drum 21. Reference numeral 42 denotes an opening of the lid member 22 and the stepped cylindrical bracket 38.
This is a sealing member for sealing a gap between them. A lid fixing bracket 4 is provided at the base large diameter portion of the stepped cylindrical bracket 38.
3 is mounted. As shown in FIG. 3, the bracket 43 is slidably inserted into the large-diameter portion of the stepped cylindrical bracket 38, and is inserted through a set screw 44.
8 and a pair of seats 46, 46 mounted on the outer wall of the ring 45 in directions opposite to each other at right angles to the axis. Are provided with bolt holes 47,47. The cover member 22 is provided with screw holes (not shown) corresponding to the bolt holes 47.

[0007]

In the apparatus constructed as described above, when cleaning or other maintenance of the inside of the rotating drum is performed, FIG.
In this state, the lid fixing bracket 43 is slid to the right, the bolts 48, 48 are screwed into the screw holes (not shown) of the lid member 22 through the bolt holes 47, 47, and the set screw 44 is tightened. As a result, the lid member 22 is integrally fixed to the stepped cylindrical bracket 38. Next, cover member 2
2 are removed from the bolts 49, 49 attached to the rotating drum 21. Thereafter, when the set screw 36 is loosened and the guide holder 33 is slid to the left along the guide rod 31, the variable speed motor 37, the stepped cylindrical bracket 38,
The lid member 22, the scraper 41, and the crushing blade 40 are collectively separated from the rotary drum 21 (see FIG. 2). After the maintenance, the lid member 22 is attached to the rotating drum 21 in the reverse order.

[0008]

As is apparent from the above description, in the device of the present invention, the rotating shaft on which the crushing blades are mounted, the variable speed motor connected to the rotating shaft, and the lid member are integrally removed from the rotating drum. In addition, since a mechanism that can be attached to the apparatus is provided, even if the apparatus becomes large-scale, cleaning and other maintenance of the rotating drum can be easily performed.

In the above embodiment, the rotary shaft, the variable speed motor, and the lid member are integrally horizontally movable. However, as shown in FIG. 4, these members may be integrally vertically rotatable.
