JPS62228507A - Rake-rocking inversion type dust remover - Google Patents

Abstract

PURPOSE:To prevent the bite of long objects by a method in which a rake-fitting arm is pivotably attached to a drive chain in such a way as to enable a rake to escape into a dust remover when great forces acts on the rake. CONSTITUTION:An arm 5 is pivotably attached to a drive chain 1 through a pin 3, and a rake 11 is pivotably attached to the other end of the arm 5 by means of a pin 6. When the chain 1 is turned to the direction of U, the rollers 4 and 7 of the arm 5 and the roller 9 of the rake arm 8 run on a guide rail 10, where dust on the front face of a screen 15 is raked up by the rake 11 and discharged to an outlet. In this case, when long objects are arrested on the screen 15, the arm 5 pivots around the pin 3 to the direction of A, and the rake 11 is allowed to escape to avoid the bite of the long objects.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a dust remover that installs a screen in a waterway that takes water into treatment equipment for water supply, sewage, etc., and scrapes up garbage, etc. caught on the screen. It is something.

[Conventional technology]

A swinging tow lever is connected with a pin hinge to an endless chain installed along the screen, and an overturning rake, which has two pairs of guide rollers on the left and right attached with pin hinges at its tip, is guided by inner and outer guide rails, and at the bottom of the guide rail. This dust remover was proposed in Japanese Patent Publication No. 60-16530, and has a structure in which the inner and outer guide rails are widened vertically and can be swung by a traction lever, and at the discharge section, the width of the inner and outer guide rails is widened so that the rake falls over.

[Problem that the invention seeks to solve]

In the conventional technology, the rake is guided by the inner and outer guide rails, so if a long object is captured along the screen, the rake will not move anywhere other than the lower transition area where the inner and outer guide rails are widened vertically. The machine will stop due to debris being trapped.

In addition, since guide rollers are attached to only the rake to guide it, the traction lever swings to the rear of the screen at the discharge section where the width of the inner and outer guide rails is widened, and the rake does not fall over enough to remove the raked up debris. The disadvantage is that it is difficult to carry out completely.

An object of the present invention is to provide a dust remover that can widen the swinging range of the rake for long pieces of garbage and completely remove the raked up garbage at the discharge section without stopping the machine. .

Means for Solving Problem C] In the present invention, an arm is connected with a bin hinge to a pair of left and right endless chenos provided along the screen, a guide roller is installed between the chenos and the arm, and a raking direction is set at the tip of the arm. A rake with a pair of left and right guide rollers attached to the front is connected with a bin hinge, and a guide roller is attached to the chain side, and an outer guide rail is installed on the ascending side and an inner and outer guide rail is provided on the descending side to guide the rake when ascending the screen surface. To provide a rake swinging reversible dust remover which is capable of swinging and is further characterized in that the guide rails of the arm guide roller and the rake guide roller are branched at the discharge section to make the rake fall over smoothly.

[For production]

According to the present invention, the rake does not get caught in the elongated garbage caught on the screen by the guide rail, and the raked up garbage can be completely discharged.

〔Example〕

FIG. 1 is a diagram showing a schematic side view of the rake-oscillating reversible dust remover according to the present invention, in which the screen 15 is installed diagonally at a position crossing a waterway with the upper part tilted slightly toward the downstream side with respect to the water flow. has been done. Blocks above and below the screen) 13a,
13b, and an endless chino 1 is bridged between the sprockets. An attachment 2 is fixed to the chino as shown in FIG. 2, and a bottle 3 is fixed to the attachment. Further, an arm roller 4 is rotatably provided on the bin 3, and the front end of an arm 5 is swingably attached to the end of the bin 3. A bin 6 is attached to the rear end of the arm 5, and an arm roller 7 is rotatably provided on the bin 6, and the rear end of a rake arm 8 at the other end of the bin 6 is tiltably provided. Further, a rake roller 9 is rotatably provided at the front end of the rake arm 8. The arm roller 4. The arm roller 7 and the rake roller 9 are disposed so as to run on a guide rail 10 - in a straight line.

Further, the rake roller 9 is caused to run inside the arm roller 7° than the rake roller 9.

The rake arms 8 are provided symmetrically, and a rake 11 is provided between them. The rake is provided with the bin 6 portion.

As shown in FIG. 1, the guide rails 10 are provided in parallel to the chino 1 over almost the entire area. In addition, the guide rail 10 is branched and curved toward the downstream side of the waterway only at the portion where the rake roller 9 travels at the discharge portion (b) above the screen, forming a branch rail 10a. In addition, the discharge section (b)
and guide rail 1 in the rake return area (c)
Ejection section auxiliary rail 12 installed in parallel with 0. A return section auxiliary rail 12a is provided, and a flange 14 serving as a rail substitute is provided on the upper sprocket 13a in correspondence with the auxiliary rail. Note that (a) shows the rake area.

The upper sprocket 13a is driven by a drive motor (not shown).
As the is driven, the ceno rotates in the direction of arrow U,
Along with this, the rake 11 is pulled up and scrapes up the dirt accumulated on the screen.

If a long piece of garbage is caught on the screen 15 and a large force is applied to the rake 11, the arm 5 swings in the direction of arrow A around the bin 3, and the rake 11 escapes. and,
When the arm 5 passes the obstacle, it rotates toward the screen due to its own weight, returns to its normal position, and continues the raking operation.

Next, when the guide rail 10 reaches the discharge area, the branch rail 10a is branched and curved, so as the rake roller 9 runs on the rail, the rake 11 moves behind the screen 15 as shown in FIG. 4 due to the weight balance of the rake 11. When the vehicle falls down, garbage falls from the rake 11 and is discharged. At this time, it may be scraped off using a wiper (not shown).

The rake 11 advances to the upper sprocket 13a while falling, the arm roller 7 is guided by the guide rail 10 and the flange 14 of the upper sprocket 13a, and the arm 5 and rake 1 rotate following the upper sprocket 13a.

The rake 11, which is still falling, rotates toward the arm 5 and returns to its original position. After the arm roller 7 guided by the upper sprocket 13a is reversed, it is guided by the two guide rails 10.12a and reaches the lower sprocket 13b.

〔Effect of the invention〕

According to the present invention, when a long piece of garbage is caught on the screen, the 7-m swings, the rake escapes, and there is no longer a stoppage due to jamming, and the rake falls over at the discharge section, allowing the garbage to be completely discharged. .
