Abstract

PURPOSE:To rake up large clump of dregs by increasing the pushing force of a rake to a screen by connecting a vertically movable wire rope to the rake in such a way as to provide a rising force and a turning force for the rake. CONSTITUTION:A waterway 13 is provided with a rake guide path 15 situated on the upstream sides on both ends of the widthwise direction of a screen 14 set transversely in the waterway 13 in parallel with the screen 14 and also with a rake 21 rotatably attached around the horizontal axile to the supporter 16 of the rake. A wire rope 43 is connected to the rake 21 in such a way as to provide a rising force and a turning force for the rake 21 when the vertically movable wire rope 43 is rolled up. When the rope 43 is rolled up, the rake 21 is pulled by the rope 43 and a rising force and a turning force toward the direction of A are given to the rake 21. The rake 21, thereby, is guided to the rake guide path 15 under the condition that a roller 27 attached to the tip of the rake 21 is strongly pushed on both ends in the widthwise direction of the screen 14. The rake 21 is then raised along the front face of the screen 14 and rakes up clumps of dregs arrested on the screen 14.

Description

[Detailed description of the invention] The present invention relates to a wire rope dust remover.

A wire rope type dust remover is known as one of the most popular methods for removing wrinkles by scraping up the residue collected on screens in waterways.
There is. As shown in the first section, this wire lobe type dust remover winds up a hoisting wire rope (1) and a closing wire rope (2) using a winding device (3) to create a rake (
4) C rise along 4th screen (5), rake (
4) to scrape up the residue collected on the screen (5), and as shown by the imaginary line, the rake is scraped up by reaching the upper bent part of the rake (4) or the rake guide path (6). (4) In a downward position, the waves on the rake (4) fall, but the chute (7) causes the discharge part (8
) (discharge section (8) consisting of a conveyor device, etc.)
is transported to a predetermined location.

After that, move the cylinder device (9), rotate the arm attached to the C1 opening/closing wire lobe (2J sheave 0υ) to the position of the temporary line, and put the rake (4) in the open position. Work out the wire ropes (1) and (2), lower the C rake (4) to the screen (5), and return the arm to the position shown by the solid line to close the rake (4). Then, similar operations are repeated to scrape up and discharge the residue. However, in such a conventional wire lobe type dust remover, the force pushing the rake (4) against the screen (5) is only the force of the vehicle force acting on the rake (4) in the direction perpendicular to the screen (5). Therefore, the problem was that the pressing force was weak and it was only possible to scrape up large scum.

``Kiyoshi ψ'' aims to address the above points and obtain a wire rope dust remover that can sufficiently increase the force of the rake against the screen.

That is, the wire lobe type dust remover according to the present invention includes a pair of rake guide paths that are approximately parallel to a screen disposed across a waterway and located at the upper end of the screen in the width direction; A rake support that is movable along a guide path and a rake that is rotatably attached to the rake support about a horizontal axis are provided, and one end of the rake has a wire wound around a winding device. Move the first end of the wire lobe from the winding 1 of this wire robe to the tip or the 6th screen side! I
When the wire robe is wound up and the rake is raised, a rotating force is applied to the rake to move the tip of the lobes toward the screen, causing the rake to rise. Since it is forcibly pressed against the screen, it is possible to obtain a sufficiently large pressing force, and even if the liquid is large, it will be scraped up to the surface of the river.

Hereinafter, one embodiment of the present invention will be explained based on the drawings. Second

A winding drum for lifting and lowering is fitted and fixed to both knitting parts of 4, a winding drum for opening and closing is fixed to the center of the rotating shaft, and a frame.
The lifting sheave end of the 2E installed on the upper end surface and the arm part are supported rotatably around the horizontal axis using a bridge and are attached to a bent arm that is swung by a cylinder device (toward). The winding drum (7) has a wire robe for lifting and lowering, and the winding drum for opening and closing (7) has a wire rope for opening and closing. The -@ side of the wire lobe is wound up respectively. The other end of the lifting wire lobe is connected to the upper end of the lifting sheave trowel and the plate of the C rake guide path via the sheave 4 attached to the rake support OQ (No. 10).
The other end of the opening wire lobe is connected to one end of the first sail body 4 via the enclosure sheave @Il.
