Description

[Detailed Description of the Invention] This invention relates to a packet type rake in a wire rope type dust remover.

Conventionally, the rake in a wire rope type dust remover installed in waterways, water intakes, etc., for example, in a trash car, is raised and lowered by winding and unwinding a hoisting rope on the upstream front of the bar screen, and is opened and closed by a wire rope for opening the rake. In particular, it is forced to lower and close under its own weight by unwinding the wire rope.

By the way, in recent years, with the spread of plastic bags and other vinyl products, many plastic bags are mixed into the garbage, and when these bags get caught in the bar screen, they become entangled with the bar screen due to the current, making it difficult to remove them with a normal rake. However, there were other problems, such as the fact that it was difficult to remove because it also included other garbage.

This idea was made in view of the above-mentioned circumstances, and allows the claws of the rake to scrape up or lower the debris hanging on the bar screen during the rising and descending strokes of the rake, thereby ensuring reliable and easy dust removal. The purpose is to obtain a rake that allows work to be carried out smoothly.

Hereinafter, embodiments of this invention will be described in detail with reference to the drawings.

FIG. 1 is a front view of the rake according to this invention, with the right half shown with the main rake removed and partially cut away.

The packet type rake according to this invention has a base end 3A of a main rake 3, which is opened and closed by a wire rope 2, mounted on the upstream front surface of a bar screen 1 installed in a waterway, water intake, etc. In a dust remover which is pivotally connected to a roller case 5 and is raised and lowered by winding and unwinding a hoisting wire rope 6, an auxiliary device is provided with upper and lower claws 7 and 8 formed between the left and right roller cases 5. rake 9
A guide roller 10.11 is pivotally attached to the upper and lower ends of the auxiliary rake 9, respectively. The auxiliary rake 9 is connected to the vicinity of the pivot point of the main rake 3 via the link arm 13, and when the main rake 3 is closed, the tip 3B of the main rake 3 is connected to the bottom of the auxiliary rake 9. It is configured so that it comes into contact with the side claws 8 to hold dirt, and the upper claws fit between the bar screens 1.

One main rake 3 has two rake flexures at both ends.
1814 is provided, and the proximal end 3A of each rake frame 14
are fixed to the shafts 15, respectively, and the shafts 15 are fixed to the roller case 5.
It is pivotally connected to the upper end of the bushing 16 through a bushing 16.

This shaft 15 is fitted with a gold wire 17 around which the end of the winding wire rope 6 is wound around the opposite inner end.

In addition, the flannel 1 to the bar 18 are obliquely fixed to the tip 3B of the main rake 3, and the lower end of this flat bar 18 is attached to the bar.
Positioned close to screen 1, bar 18 to furazo 1
The lower end of the rake body 9A of the auxiliary rake 9 and the -F side claw part 8 are made to come into contact with the back surface (on the bar screen 1 side) of the auxiliary rake 9.

The guide roller 4 for guiding the rake is pivotally mounted by a shaft 19 at the upper and lower portions of the roller case 5 and closer to the outside.

The auxiliary rake 9 is removably attached to the rake main body 9A and its upper and lower ends via flat I-bars 20, 21, 22, 23, respectively. A triangular lower claw portion 8 when viewed from the side, a fixed shaft 24° 25 protruding downward from both left and right ends, and a guide roller 10, 11 rotatably attached to the fixed shaft end.
It consists of

The upper and lower claw portions 7 and 8 are arranged at the same interval as the plate material constituting the auxiliary rake main body 9A, and both claw portions 7
The rear end surfaces 7A and 8A of , 8 are parallel and the upper claw part 7
The rear end surface 7A of is located at the rear.

That is, as shown by the solid line in FIG. 3, when the rake is closed, the upper claw part 7 is positioned between the constituent bars of the bar screen 1 so that it can rake up dirt, and the lower claw part 7 The side claw portion 8 is located forward of the bar screen 1, and is brought into contact with the flat bar 18 at the tip of the main rake 3 at the front lower end surface 8B.

The fixed shaft 25 of the force idle roller 11 is fixed toward the front so that it is located further forward than the guide roller 10.

The elongated hole 12 into which the guide roller 10.11 is fitted is provided in each inner plate 5A of the roller case 5, and the upper half thereof is parallel to the bar screen 1.
The lower half has a lower end located toward the front and is inclined with respect to the bar screen 1, and is shorter than the center distance of the guide rollers 10.11.

Therefore, when the auxiliary rake 9 moves upward relative to the roller case 5, as shown by the two-dot chain line in FIG.
The upper claw part 7 is almost removed from between the bar screen 1, and the lower claw part 8 is inserted between the bar screens 1.

The lower end of the link arm 13 is pivotally attached to the upper fixed shaft 24 via a bush 26, and the upper end of the link arm 13 is bent rearward to connect the shaft 1 of the rake arm 14.
It is pivotally connected to a mounting shaft 27 which is fixed at a position forward of 5 through a bush 28.

, 7 Therefore, the auxiliary rake 9 follows the opening/closing operation of the main rake 3 and is not moved downward via the link arm 13.

Note that 29 is a guide rail on which the force idle roller 4 is secured and guided.

According to the packet type rake according to this invention, when the rake opening/closing wire rope 2 is operated to open the main rake 3, the attachment shaft of the link arm 13 is rotated as the main rake 3 rotates upward. The position of 27 moves upwards and the auxiliary rake 9 is therefore pulled up.

At this time, the auxiliary rake 9 has its guide roller 10.1
1, the lower claw part 8 opens the bar crease.
- When the wire rope 6 is unwound with the main rake 3 in the open state (the state shown by the two-dot chain line in FIG. 3), the upper claw part 7 comes out from between the bar screens 1. The main key 3 is guided down by the guide rail 29 together with the auxiliary rake 9, and the lower claw part 8 of the auxiliary rake 9 scrapes down plastic bags and other garbage hanging between the bar screens 1.

In this way, the garbage is transferred to the main rake 3 and the auxiliary rake 9.
It becomes possible to grasp it and reaches the lower limit.

Next, when the opening/closing wire rope 2 is unwound, the main rake 3
rotates downward to the state shown by the solid line in FIG.

At this time, the link arm 13 also descends to push the auxiliary rake 9 downward, and the lower claw part 8 of the auxiliary rake 9 moves forward from the bar screen 1 by the guidance of the elongated hole 12, and the main rake 3 The upper claw part 7 is inserted between the bar screens 1 while coming into contact with the lower end part 3B of the bar screen 1.

In this way, the garbage is held by the packet made up of the main rake 3 and the auxiliary rake 9.

Therefore, by winding up the hoisting wire rope 6,
The main rake 3 and the auxiliary rake 9 lift up carrying the garbage, and at the same time, the upper claw part 7 is located between the bar screens 1 and scoops up plastic bags and other garbage hanging thereon.

Note that when the rake is raised, the upper end surfaces of the auxiliary rake 9 and the upper claw portion 7 are inclined so that the garbage can easily fall into the main rake 3, so that the garbage can be easily and smoothly removed from the bar crease. - can be removed from Part 1.

The packet-type rake according to this invention is configured in a packet shape by a 1-mill rake 3 and an auxiliary rake 9, and the auxiliary rake 9 is provided with claws 7 and 8 at the top and bottom, so that it can collect garbage. It is possible to securely hold and scrape up garbage, and also to scrape off garbage such as plastic bags that are entangled with the bar screen 1 in both the ascending and descending strokes of the rake, thereby making it possible to do so reliably and easily.

It is also possible to perform dust removal work efficiently.

Further, the operation of the auxiliary rake 9 is automatically and reliably performed by the main rake 3 through the link arm 13 and the elongated hole 12 of the roller case 5, and the structure is simple and robust.
In addition, the system is stable in operation, easy to maintain and inspect, and has the advantage of being able to effectively and efficiently remove dust from towers that do not have corridors or the like.
