Description

[Detailed Description of the Invention] In the process of treating sewage, sewage, clean water, etc., water channels are used to remove garbage contained in the inflowing water and prevent it from adversely affecting pumps, etc. in the next process. A mechanical dust remover is attached to which a screen is installed across the screen and scrape up the garbage caught on the screen. Since the rake c is directly connected to the endless chain b installed, if bulky garbage or foreign objects are caught, there is no chance that they will get stuck in the rake and cause the machine to become inoperable. However, there are drawbacks such as the need to manually remove incoming foreign matter.

The present invention has been developed to address the above-mentioned drawbacks, and includes a left and right pair of endless flexible members for moving rakes disposed along a screen provided at a position crossing a waterway. , a pair of left and right roller guides disposed adjacent to the endless mirror member, a pair of left and right traction levers that are mounted on the endless mirror member and swing, and a pair of roller guides disposed between the tip portions of the traction levers. a rake that is moved by the inorganic movable member; and two pairs of left and right guide lobes disposed at both ends of the rake and guided into the roller guide; , a rake raising transition part in which the outer wall interval is formed vertically large so that the rake is swingably suspended by the towing lever, and is moved to the lower part of the screen in an inverted position; and a rake raising transition part of the roller guide. It is characterized by a configuration in which the outer wall interval is formed to be medium wide in the area adjacent to the wiper at the upper side, and a striped bamboo scraping area is provided for the rake to work on the downstream side, and its purpose is to remove bulky waste. The object of the present invention is to provide a oscillating type dust remover which can be scaled up without any trouble even if foreign matter is captured, and which can operate normally. Since the present invention has the above-mentioned configuration, even if the streaks caught by the screen become coarse and concentrate at the bottom of the screen, the rake is reversed and oscillated at the rake upward transition section provided at the bottom of the roller guide. At the same time, the rake is moved toward the scooting side, that is, the downstream side, at the section of the clearing port on the upper part of the rising side of the rake, and the scraping performance of the wiper is enhanced, and the scraping performance of the wiper is improved, and the scraping performance of the wiper is improved.

The left and right pair of swinging levers 12 and 1 are arranged in a horizontal position so as to
Both ends of a rake 8 whose tip end side twill portion is formed in a mirror-tooth shape are pivotally connected between the swinging side tip portions of the rake 8 by pins 13, 13,
The same key 8 is disposed so as to be movable within a range of about 6 pins in the direction of the arrow shown in FIG. The two pairs of left and right guide rollers 10 provided at both ends of the rake 8 have guide rollers 10 rotatably attached to both outer ends of the rake 8, respectively, and the two pairs of left and right roller guides 14,
14, the arrangement is such that it is guided between the outer walls.

More specifically, as shown in FIG. 6, on the lowering side of the left and right pair of endless chains 5, 5, that is, on the rake lowering side, the rake 8 is
is lowered while being pulled to the upper side via the swing lever 12, and when it reaches the lower part of the roller guide 14, the distance between the lower inner wall 14a and the lower outer wall 14b is formed vertically large as shown in FIGS. Then, the rake 8 is suspended by the swing lever 12, and the rake 8 is inverted and placed under the screen 1, and the rake 8 is moved together with the swing lever 12 as shown in FIG. As shown in the dotted line, a swingable rake-up transition section is provided, and the structure is such that the rake 8 causes the rake to move up.

Further, as shown in FIG. 8, a pair of left and right roller guides 14,
14 on the rising side of the rake (right side in the figure), that is, wiper 1
Inner wall 1 of the roller guide 14 in the adjacent part of the 5 arrangement position
4c and the outer wall 14d is formed to be medium wide, so that the inner wall 1
4c and the outer wall 14d, the rake 8 is formed into a section where the rake 8 is rotated around the pin 13 and moved slightly toward the screening 1 side, that is, the downstream side of the water flow, and the rake 8 is configured to be rotated slightly toward the screen 1 side, that is, the downstream side of the water flow, and the rake 8 is configured to rotate around the pin 13 as a center of rotation. The movement is designed to make it easier for the wiper 15 to scrape off the dirt lifted up by the rake. Furthermore, a lever guide 16 adjacent to the drive sprockets 3, 3 is provided within the upper end portions of the left and right pair of roller guides 14, 14, and is configured to smoothly rotate and transfer the rake 8 together with the swing lever 12. ing.
