Description

  The present invention relates to a dust remover that lifts up dust collected on a screen by a rake that moves up and down.

  Conventionally, as a dust remover, a so-called rake wire rope type, rotary rake type, rake type with a telescopic device, etc. are known. In the rake wire rope type, a rake suspended by a linear body is arranged in a water channel. In the rotary rake type (for example, Patent Document 1), an endless conveyor is formed by a lower end wheel submerged in a water channel and a driving upper wheel on the water channel. Move the rake along.

  In the above rotary rake type, the tilt angle of the screen can be set relatively freely and the depth condition is not easily restricted. However, the lower end wheel and the conveyor chain are always submerged, so that the maintenance is difficult. Since the posture of the rake cannot be changed, if a piece of wood or the like bites into the screen and the rake cannot move, it takes time for the restoration work and it is not suitable for installation on a screen with a large depth.

  On the other hand, in the conventional rake wire type (for example, Patent Document 2), the left and right rollers of the rake are moved up and down along the screen, and an open / close rope is attached to the rake. It closes and scrapes the dust adhering to the screen. However, because the rake falls by its own weight, it may be thrown into the water flow or ride on the dust on the front of the screen to become an abnormal posture and may not be able to remove dust.

All conventional dust removers can remove the dust trapped by the screen, but cannot remove driftwood floating in front of the screen, and require a dedicated crane or work boat.

When the expansion / contraction means 23 is driven to make the expansion / contraction arm 21 substantially vertical and rotate in the direction to open the rake 33, the dust remaining on the rake 33 falls into the hopper 44.

  If dust is floating on the water surface in front of the screen 2, the upper body 16 is rotated horizontally without moving along the traveling rail 12, and the direction of the hoisting arm 17 is adjusted to the dust on the water surface. By operating the hoisting arm 17 and the expansion / contraction means 23, the open / close rake body 34 is positioned on the surface of the water, the dust is trapped on the open / close rake body 34 and pulled to the screen 2, or the dust pool collected in front of the screen 2 by the open / close rake body 34. Can be arranged so that they can be easily swirled. Of course, dust can be picked up by the open / close rake body 34 and collected in the hopper 44.

  Thus, in this embodiment, corresponding to claim 1, the dust removal provided with the screen 2 installed in the water channel 1 and the rake 33 provided on the front surface of the screen 2 so as to be lifted and lowered to sweep up the dust on the screen 2. In this machine, a hoisting arm 17 provided on the water channel 1 and a telescopic arm 21 swingably provided on the hoisting arm 17 are provided, and a rake attachment body 31 is provided on the distal end side of the telescopic arm 21. Since the rake attachment body 31 is provided with an open / close rake 33 that opens and closes to a screen engagement position and a non-engagement position, the telescopic arm 21 is extended, the open / close rake 33 is aligned with the screen engagement position, and the telescopic arm 21 is moved to the screen 2. By opening and closing along the open / close rake 33, the open / close rake 33 scoops up the dust and can deal with the screen 2 including the vertical. Then, the dust that has been lifted can contract and retract the telescopic arm 21, raise the undulating arm 17, and open and close the open / close rake 33 to drop and accumulate at a predetermined location on the water channel 1.

  Thus, in this embodiment, in correspondence with claim 3, the telescopic arm 21 is rotatably connected to the hoisting arm 17, and the telescopic means 23 is provided between the hoisting arm 17 and the telescopic arm 21. Since it is provided, the rake 33 can be raised with an appropriate pressing force by actuating the expansion / contraction means 23 so as to press the rake 33 against the screen 2 with an appropriate force when scraping the dust.
