Abstract

PURPOSE:To enable always the title device to spread sand uniformly, adjust a rotary speed of a drum and control easily a spreading quantity of the sand, by a method wherein sliding contact of a drum constituted by scattering and forming recessed parts on a circumferential surface is performed turnably to a lower opening part of a hopper. CONSTITUTION:A chuter 3 for scraping-off is provided on an opening part 2 of the lower part of a hopper 1 of a sand spreading device which is provided with a drum 5 where recessed parts 4 are formed by scattering on a circumferential surface of the same performing sliding contact with the chuter 3. The recessed parts 4 provided on the circumferential surface of the drum 5 are filled with sand 8 of the inside of the hopper 1 and the sand 8 forced out of the recessed parts 4 in accordance with a rotation of the drum 5 is scraped off by the chuter 3, Then the drum 5 is turned, the sand 8 is dropped to the lower part and spread over a tile 9 which passes through the lower part of the drum 5 and is under an uncured state.

A certain amount of sand (C) is continuously supplied to a second hopper (B) located below, and a feeder (C) is installed inside the second hopper (B). d) While stirring the sand (c), the pie grater (e) set up on the outside of the second hopper (b) vibrates the entire second hopper (b), causing its vibration. The vibration causes the sand (C) to be scattered from the lower opening (H) of the second hopper (B), and the sand (C) is scattered onto the uncured roof tiles (not shown) passing below. It is something.

盛進展に寄与せんとするものである。Since the conventional sand sprinkling device is constructed as described above, it has had the following problems. In other words, it is difficult to always reliably spread a constant amount of sand (C) because the shapes and sizes of the sand (C) are different, and the amount of scattered sand (C) can be reduced by using a vibrator (E). It was extremely difficult to control the vibrations alone. In order to solve the problems in the conventional technology, the researchers who achieved the present invention, after a long period of painstaking efforts, provided society with a highly novel and highly useful sand spreading device. We aim to contribute to the further prosperity and development of this industry.
