The chain 8 is wound around the sprocket 7, and the sprocket 9 is elastically pressed against the chain 8 to prevent the chain 8 from loosening. That is, the driving torque is transmitted from the sprocket fixed to the other end of the pulley shaft 3 to rotate the pulley 2, and the torque of the pulley 2 is transferred to the rotating shaft 11 via the sprocket 6, the chain 8 and the sprocket 7. The rotary blade body 10 is rotated by being transmitted. The rotation transmission mechanism 5 can employ appropriate means other than the illustrated example (for example, a rotation transmission mechanism using a gear train, a rotation transmission mechanism using a belt and a belt wheel, etc.). The sprocket 9 that is elastically pressed against the chain 8 faces away from the chain 8 when a relatively large object such as dust is caught between the rotary blade body 10 and the conveyor belt 1. The structure is designed in consideration of safety so that the rotation transmission mechanism 5 and the like can be prevented from being damaged by moving to.

The rotary vane body 10 is configured by arranging three vane pieces 12 in the shape of a long strip on a rotary shaft 11 at substantially equal intervals along the rotational direction and in the radial direction. The piece 12 is composed of a substantially elongated strip plate-shaped core portion 13 directly fixed to the rotary shaft 11, and a rubber exterior portion 14 that covers a half of the core portion 13 near the tip. That is, consideration is given so that the outer belt portion 14 contacts the surface of the conveyor belt 1 to reliably prevent damage to the conveyor belt 1 itself. The specific configuration, shape, size, material of the rotary blade 10, and the specific configuration, shape, size, material, number, etc. of the blade pieces 12 are not limited to the illustrated examples.

The scraper 15 has a substantially long strip plate shape, and is fixed to the upper end portion of the scraper support body 16 arranged closer to the tail pulley than the rotary blade body 10 so as to be interchangeably mounted. In addition, the tip edge of the scraper 15 is arranged in a state of being slightly inclined in the moving direction of the conveyor belt 1 in the left-right direction so that the conveyed product attached to the conveyor belt 1 can be smoothly dropped. The scraper 15 is formed of a material that wears itself so as not to damage the conveyor belt 1. Further, the scraper 15 is configured so that the pressure contact force on the surface of the conveyor belt 1 by the leading edge thereof can be adjusted by rotating the adjusting bolt 18 that moves the scraper support 16 up and down.

Further, below the scraper 15, a receiving plate 17 for receiving the conveyed articles to be scraped off is arranged so as to be fixed to the scraper support body 16. Moreover, on the left and right of the upper part of the receiving plate 17, the cleaning liquid is provided. A nozzle 20 for ejecting the like is arranged. That is, the receiving plate 17 is configured to receive the conveyed object to be wiped off, and the nozzle 20 is configured to eject the cleaning liquid or the like to promote the downward movement of the conveyed object on the receiving plate 17.

By the way, the specific configuration, shape, size, material of the cleaner device S, the specific configuration, shape, size, material of the scraper 15, the specific shape, size, material of the receiving plate 17, the specific configuration of the nozzle 20.

[Effect of device]

 Therefore, the cleaner device S according to claim 1 includes the rotary blade body 10 arranged below the head pulley 2 of the belt conveyor A and the scraper 15, and the rotary blade body 10 transmits the rotational force of the pulley 2. The rotary shaft 11 that is rotated by rotation is provided with a plurality of blade pieces 12 that are arranged on the rotating shaft 11 at substantially equal intervals along the rotation direction. Is formed so as to come in contact with the surface of the conveyor belt 1 against the moving direction of the conveyor belt 1, and the scraper 15 is arranged closer to the tail pulley than the rotary blade body 10 so that its leading edge comes into contact with the surface of the conveyor belt 1. Since it is configured so that the conveyed material formed and adhered to the conveyor belt 1 can be wiped off by the rotary blade body 10 and further dropped by the scraper 15, it is relatively sticky. When a high-conveyance object (for example, sludge) is conveyed by the belt conveyor A, the conveyance object adhered to the conveyor belt 1 can be reliably and cleanly dropped by the rotary blade body 10 and the scraper 15. . In other words, the conveyed material attached to the conveyor belt 1 does not adhere to the belt conveyor A itself (for example, rollers), which has a good effect on the belt conveyor A itself, which enables long-term use and also the conveyor belt. It becomes possible to prevent the meandering of 1 and the like. Also, the rotating force of the pulley 2 can be used to rotate the rotary blade body 10, thus eliminating the need for a new power source, which is economical, and a cleaner device which can be easily mounted on the existing belt conveyor A. It becomes S. Moreover, the cleaner device S has a simple structure, is highly durable, is hard to break down, is easy to maintain, and is relatively inexpensive.

In particular, in the rotary blade body 10, the plurality of blade pieces 12 are arranged on the rotary shaft 11 at substantially equal intervals along the rotation direction, so that a relatively sticky conveyed object (eg, sludge) rotates. The cleaner device S makes it difficult to adhere to the blade body 10 and can be easily removed even if it adheres, and the conveyor belt 1 can be reliably cleaned for a long time, and at the same time, it is easy to handle and the work efficiency can be improved. Becomes

Further, in the cleaner device S according to a second aspect of the present invention, a receiving plate 17 for receiving the conveyed articles to be scraped off is arranged below the scraper 15, and a nozzle 20 for ejecting a cleaning liquid or the like is arranged above the receiving plate 17. As a result, the conveyed product blown off from the conveyor belt 1 can be reliably received by the receiving plate 17, and further, the cleaning liquid ejected from the nozzle 20 ensures the downward movement of the conveyed product on the receiving plate 17. I can be encouraged.

Further, in the cleaner device S according to claim 3, since the tip edge of the scraper 15 is slightly tilted in the left-right direction in the moving direction of the conveyor belt 1, the conveyed objects adhering to the conveyor belt 1 can be smoothly moved. And you can drop it cleanly.
