Abstract

PROBLEM TO BE SOLVED: To use s dust collector even for a low waterway by providing plural serapers with elastically contacting mechanisms for the surface of plural rakes to rotate plural semicircular screen bars with both ends fixed. SOLUTION: Refuse flowing-in from a waterway is blocked even at the bottom of a waterway by a screen bar 1, lifted up at the bottom position of the waterway by a rake 2 gradually protruded from the surface of the screen bar 1 to the outside and moved backward along the circmuferential surface of the screen bar 1. At this time, as a scraper 6 is in slide contact with the surface of the rake 2 at all times. the lifted refuse is prevented from dropping. When the rake 2 becomes rotated near a refuse storage box 23, the rake 2 draws in the axial in the axial direction 17 by a cam rake 5 so that the refuse can be scraped off by the scraper 6 in slide contact and stored in the refuse storage box 23 along a refuse dropping plate.

Description

Detailed Description of the Invention

2. Description of the Related Art When introducing a larger amount of water than a river for agriculture or industrial use, a waterway is provided and introduced. However, a large amount of garbage, such as cut grass, foliage, jute empty cans and plastic containers, is also used. A dust remover is installed at the entrance of the waterway to remove the dust, and only water is introduced. When removing dust on a relatively large scale, rotate the disc-shaped net and remove the dust collected by the net with a fountain, or rotate the net vertically on a belt conveyor, and fountain the collected dust. Is generally adopted, but in either case, the cost is high and there is a problem in terms of profitability when the operation is performed on a relatively small scale. The development of a machine was desired.

[0003]

SUMMARY OF THE INVENTION The present invention has been developed in view of the above-mentioned problems, and has been developed for a relatively small scale, especially for a waterway which is cost-effective even when used in a low waterway which has heretofore been considered difficult. It is intended to provide a dust remover.

[0013]

The above is an embodiment of a water channel dust remover according to the present invention. According to the present invention, the following remarkable effects can be obtained. 1) It is possible to provide a dust remover that can be used in a low water channel that has been considered difficult in the past. 2) Since the screen bar is completely grounded to the bottom of the water channel, dusts larger than the width of the screen can be completely prevented. 3) The rake does not come into contact with the bottom of the water channel because the rake moves to the inside of the screen bar at the time of backward rotation and lower rotation by using a cam rail. For this reason,
The waterway dust remover of the present invention can be installed without modifying the existing waterway bottom. 4) For driving, a pin gear chain is attached to a cylindrical body and directly rotated by a pinion of an electric motor with a cyclo gear reducer, so an electric motor with high efficiency and a relatively small capacity can be used. 5) Since the dust remover integrated in the factory can be carried into the site, installation work can be performed in a short time.
