Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a simple reciprocating dust remover suitable for small rivers.
[0002]
[Prior art]
As disclosed in JP-A No. 2002-317428, a dust removal equipment that is generally used at present is provided with a flat screen obliquely in a water channel, and a comb-shaped rake that moves on the upper surface side is provided with a wire rope or chain. A device that is moved up and down by a driving device via a device is used.
[0003]
Although what is disclosed in the aforementioned JP-A-2002-317428 is a simplified rake lifting mechanism, the dust removal equipment using this type of flat screen has a higher position of the hoisting device, and is smaller. When used in rivers, facilities that protrude above the ground are obstructive, so it is desirable that the ground facilities be as low as possible.
[0004]
In addition, there has been a demand for a rake that requires a small driving force.
[0005]

[0006]
[Problems to be solved by the invention]
Accordingly, the present invention is intended to provide a simple reciprocating dust remover that has low ground facilities suitable for small rivers such as urban areas and that requires only a small driving force.
[0007]
[Means for Solving the Problems]
The present invention has been made to solve the above-described problems. The screen has an arc shape, and the rake attached to the swing arm is configured to move along the upper surface of the screen. The rake is moved up by a stopper provided on the swing arm so that the rake does not rotate downward. When the rake is lowered, the rake is rotated by the path switching piece and the attitude switching protrusion or trochanter provided on the guide rail. Thus, a non-scraping operation state is established.
[0008]
That is, according to the present invention, a screen curved in an arc shape with the overhanging side facing upstream is disposed in the water channel W, and comb-shaped rakes are disposed on the overhanging side, and the rake is provided on both sides of the screen. An arcuate guide rail that is attached to the moving arm so as to be swingable and is moved up and down by a driving device, and that uses a channel material on both side walls of the water channel W upstream of the screen. Is provided concentrically with the screen, and a path switching piece is provided in the upper part of the guide rail in the form of a check valve, and a lowering posture switching guide part is provided in the lower part. A reciprocating type removal characterized by providing a posture change projection or trochanter to be combined and a stopper for stopping the rake from rotating downward when the rake is raised on the swing arm It is a machine.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
The drawings show an embodiment of the present invention. FIG. 1 is a longitudinal side view, FIG. 2 is a front view, and FIG. 3 is a plan view.
[0010]
In the figure, reference numeral 1 denotes a screen curved in an arc shape, and is provided in the water channel W with the projecting side facing the upstream side.
[0011]
Reference numeral 2 denotes a rake that is swingably attached to swing arms 4 and 4 that are swingably attached to the side walls 3 and 3 of the water channel W, and is manually operated via a wire rope 5 having one end connected to the attachment portion 2a. The winch 6 is configured to be moved up and down along the upper surface of the screen 1 and not to be rotated downward by the stoppers 7 and 7 provided on the swing arms 4 and 4 when it is raised. The oscillating arms 4 and 4 are formed in a torii shape by connecting members 4a and 4b, and the arms 8 and 8 provided on both sides of the rake 2 are respectively provided with posture changing projections or rolls on the rake 2 respectively. A child 9 is provided.
[0012]
Reference numerals 10 and 10 denote arcuate guide rails for maintaining a lowered posture using channel members attached to the side walls 3 and 3 of the water channel W, and are provided concentrically with the screen 1 on the upstream side of the screen 1. . The guide rails 10, 10 are each provided with a path switching piece 11 in the form of a check valve, and at the lower part, a guide unit 10a for lowering posture switching.
[0013]
The guide rails 10 and 10 guide the posture change projections or the trochanters 9 provided on both sides of the rake 2 when the rake 2 is lowered, and the rake 2 is moved in the opposite direction against the lifting force of the manual winch 6 when lowered. The posture of the rake 2 is maintained in the non-raising operation state by rotating.
[0014]
When the rake 2 is lowered, the posture switching protrusions or the trochanter 9 provided on the rake 2 are disengaged from the guide rails 10 and 10, so that the rake 2 is pulled by the wire rope 5 and rotated, as shown in FIG. It becomes.
[0015]
Accordingly, by driving the manual winch 6, the trash caught on the screen 1 is scraped up, and when reaching the top, the rake 2 becomes almost vertical downward, so that the rake 2 is placed on the transfer platform 12 installed in the water channel W. You can drop trash.
[0016]
In this reciprocating dust remover, since the screen 1 has an arc shape, the portion protruding on the water channel is lower and the frictional resistance at the time of scraping is smaller than that of a conventional device having a flat screen, so that the driving force is low. It's small.
[0017]
Since the rake 2 is attached to the swing arms 4 and 4 configured in a frame shape, the rake 2 is less likely to swing and is therefore suitable for a screen having a fine mesh width.
[0018]
【The invention's effect】
According to the present invention, since the protruding part on the waterway becomes lower, it is less obtrusive than the conventional device, and the hoisting machine can be small or manual, so it can be used for small rivers in urban areas. Is preferred.
