Next, the usage of this invention will be explained.

When the carriage 9 is in the retracted position where the traveling cylinder 13 is retracted, the rotary brush 31 is rotated by the drive of the motor 33, and the surface plate 2 to be cleaned next is sent along the mold conveyance line 1 by a distance of -mold. In the state shown in FIG. 1, when the traveling cylinder 13 is extended and the trolley 9 is moved forward, the rotating brush 31 comes into contact with the upper surface of the surface plate 2 at a predetermined position, and as the trolley 9 moves forward, the scraper 22 and the rubber scraper 1
6 comes into contact with the upper surface of the surface plate 2.

Here, the sand, flakes, slabs, etc. accumulated on the upper surface of the surface plate 2 are gradually scraped off by the rotational force of the rotating bluff 310, then scraped off by the scraper 22 and the rubber scraper 16, and dropped on the right side of the carriage 9.

After the cart 9 has moved at the forward end O in this way, a single compressed air supply source (not shown) that rotates the rotating brush 31 is used.
Compressed air is sent from the air supply pipe 41 to the spray nozzle 4.
2, the travel cylinder 13 is retracted and the truck 9 is moved backward.

Then, the rubber scraper 16, the scraper 22, and the rotating brush 31 come into contact with the upper surface of the surface plate 2 in this order, and compressed air is ejected from the blowing nozzle 42 while removing sand, dust, slabs, etc. remaining on the surface plate 2. Blow it out of the surface plate 2.

That is, the sand, scum, and slabs accumulated on the upper surface of the surface plate 2 are scraped off and actively removed by the rotational force of the rotating bluff 310, so that they can be reliably discharged to the outside of the surface plate 2.

Note that since the metal scraper 22 is installed below the swing plate 20, even if a large force is applied to its lower end, it is avoided by the swing of the swing plate 20, and the scraper 22 will not be damaged.

The housing and frame 28 are heavy on the side where the rotating brush 31 is attached, so if the rotating brush 31 is worn out, rotate the handle 3T and tilt the frame 28 to the right.
The contact force of the rotating brush 31 can always be kept constant,
Further, the rotating brush 31 may be replaced when the pointer 39 indicates the wear limit of the scale plate 40 due to the inclination of the frame 28.

Since this invention has the above-mentioned configuration, it has excellent effects such as being able to reliably and completely clean the top surface of the surface plate, easily adjusting the rotary brush due to wear, and clearly indicating when to replace the rotary brush.
