While a pair of brackets 40 are provided, a bracket 41 is also provided at the rear portion of the rear frame member 24, and a main scraper 42 is provided via the front bracket 40 and a sub scraper 43 is provided via the rear bracket 41. It is attached so that it can swing up and down. 44 is a front shaft and 45 is a rear shaft. These shafts 44, 45 may be shorter than those shown in FIG.

The main scraper 42, as shown in FIG.
It is a single plate (may be a pair of left and right) and is formed slightly shorter than both side walls 2 and 2, and a scraping plate 47 is attached to the lower end of the plate by rubber or the like. Since the scraping plate 47 is also designed to scrape up the sludge on the guide rails 8, the auxiliary scraper 30 may be omitted. On the contrary, when the auxiliary scraper 30 is configured, the scraping plate 47 may not be configured to be on the guide rail 8.

On the other hand, the auxiliary scraper 43 similarly has the side walls 2, 2.
Although the scraper plate 48 is structured to extend between two, and the scraper plate 48 is also structured in the same manner as the front side, the auxiliary scraper 43 moves forward after being scraped by the main scraper 42, so that the height thereof is 1/3. Even if it is formed to a low level, it is sufficient for scraping.

The rear shaft 45 has an auxiliary scraper 4 attached thereto.
A balancer 49 is provided so that the most backward rotation moment is generated when 3 is vertical and the most forward rotation moment is generated when horizontally raised. The balancer 49 has a dead point when the rod 50 becomes vertical, and the direction of the rotational moment is switched. The balancer 49 is vertically adjustable on the rod 50.

On the other hand, as a device for advancing and retracting the body 22,
A mount 52 provided on the machine body 22 is provided with a rotation drive device 53 that is a motor with a speed reducer. The rotary drive device 53 enables a forward and reverse drive of a drum-shaped winding wheel 54 provided in the mounting base 52 so as to be rotatable around the vertical axis. The forward rotation is the F direction in FIG. 3, and the reverse rotation is the R direction in FIG.

Orbital filament 56 wound on the wheel 54
Is a single wire rope, and the orbital line 56 is shown in FIG.
As shown in FIG.
It is hung on a sheave 59 provided on a fixed bracket 58 on the same end wall 3 and is connected to a weight adjusting type draw weight 60 via a spring 61. Both ends of the track line 56 are pulled by a weight 60 with a constant force and are balanced by springs 61, and the bracket 58 functions as a stopper. The track line 56 may be composed of only the spring 61 or only the weight 60.
Further, the weight 60 may move up and down with the water surface as a boundary. Further, the orbital line 56 may be pulled out by a recoil spring system which always acts with a constant force.

As a result, when the rotary drive device 53 rotates forward, the wheel 54 rotates in the F direction in FIG. 3, and when it rotates in the reverse direction, the wheel 54 rotates in the R direction in FIG. as a result,
The sludge attracting device moves forward or back in response to the F or R direction.

The sludge attracting device moves forward in the F direction until the main scraper 42 crosses the rear end side of the pit 4 in FIG. The auxiliary scraper 43 may also be advanced until it goes beyond the rear end side. The reverse rotation causes the sludge attracting device to return to the recovery state, and the main scraper 42 and the auxiliary scraper 4
3 is lifted like a virtual line in FIG. Main scraper 4
2 is lifted to the front and the auxiliary scraper 43 is lifted to the rear. This interlocking is switched up and down by the next clutch interlocking mechanism 63.

The clutch interlocking mechanism 63 includes upper and lower claw wheels 65 and 66 that are independently rotatable around a vertical axis 64 of the wheel 54, and an engagement / disengagement mechanism provided on the upper and lower surfaces of the wheel 54 so as to be rotatable simultaneously with the wheel 54. It has claws 67 and 68. Drive levers 71 and 72 having rollers 69 and 70 at their tips are attached to the upper and lower claw wheels 65 and 66, respectively. A support shaft 74 having a vertical axis is provided in front of the wheel 54 between the mounting base 52 and the machine body 22.
The upper and lower driven levers 75 and 76 are rotatably provided around the support shaft 74.

A front link 77 and a rear link 78 are provided on the support shaft 74 so as to rotate and respond together with the support shaft 74. The front link 77 is connected to the main scraper 42 via a ball joint 80, while the rear link 78 is connected.
Is also the auxiliary scraper 43 through the ball joint 80.
Are linked to. A track correction device 80 is provided in front of and behind the wheel 54 in the form of vertical and horizontal axes.

Now, the operation of the clutch interlocking mechanism 63 will be described. Fig. 5 shows that the sludge attracting device is moving forward and both scrapers 4
2 and 43 are in a solid line state in FIG. 1, and the upper side of the clutch interlocking mechanism 63 is shown. FIG. 6 also shows the lower side. In FIG. 5, the wheel 54 rotates in the F direction, the pawl 67 meshes with the pawl wheel 65, and the drive lever 71 also rotates in the F direction. The driven lever 75 moves from the state of the phantom line in FIG. 3 by the drive lever 71 to the roller 69 as shown by the solid line in FIG.
Come outside Therefore, even if the roller 69 rotates, it does not interfere with the driven lever 75. Also, both scrapers 42,
43, the rotation moment of the balancer 49 acts, and the scraping force acts on the main scraper 42, so that the scraping state is stably maintained.

In the meantime, under the clutch interlocking mechanism 63, as shown in FIG. 6, the driven lever 76 is positioned in the rotation orbit of the roller 70, but even if the pawl 68 rotates in the R direction, the pawl wheel 66 does not. Since they are not engaged, the driven lever 76 is not rotated. Incidentally, when the roller 70 enters the scratching state, the roller 70 is below the driven lever 76, but the claw 68 is the claw wheel 66.
6 is stopped at the position indicated by the solid line in FIG.

When the sludge attracting device is switched from the forward movement to the returning posture, the wheel 54 rotates in the R direction in FIG. 7 and the lower claw 68 engages with the claw wheel 66. This allows
The roller 70 hits the driven lever 76 and kicks from the position of the phantom line as shown by the solid line. As shown in FIG. 8, the driven lever 76 is swung out of the rotation track of the roller 70 by the balancer 49. As a result, the main scraper 42 is lifted and held via the front link 77. Further, the auxiliary scraper 43 is also lifted and held via the rear link 78. As a result, both scrapers 42, 43 are brought into a stable return state by being stopped by a stopper (not shown) when the balancer 49 moves forward.

At this time, in the mechanism above the clutch interlocking mechanism 63, as shown in FIG. 9, the driven lever 75 is rotated from the solid line position in FIG. 5 to the same position as in FIG.
Comes on a rotating orbit. However, since the pawl 67 rotates in the R direction but separates from the pawl wheel 66 and rotates, the roller 69 does not drive the driven lever 75. The upper claw wheel 66 stands by on the lower side of the driven lever 75 in the figure with the claw 67.

Although the sludge attracting device is retracted while maintaining the return state, the sludge retracting device is retracted to such an extent that the rear end of the auxiliary scraper 43 corresponds to the slanted wall 5 of the end wall 3. At that time, the rotation driving device 53 is reversely rotated in the forward direction and the wheel 54 is rotated.
Is rotated in the opposite direction of R in FIG. As a result, the upper mechanism of the clutch interlocking mechanism 63 is reversely driven from the state of FIG. 9 and the lower mechanism is reversely driven from the state of FIG. In the upper mechanism, the claw 67 meshes with the claw wheel 65 and the roller 69
9 is rotated counterclockwise (F direction) in FIG.
And the driven lever 75 is brought out of the track of the roller 69 by the balancer 49 as shown in FIG. At the same time, both scrapers 42, 43 descend and enter a state of scratching.

In the lower mechanism, the driven lever 75 comes on the rotation track of the roller 69 in conjunction with the upper mechanism as shown in FIG. 6, but the claw 68 rotates in the reverse direction (F direction) from the state of FIG. However, since it does not engage the claw wheel 66, the roller 69
Comes to the position above the driven lever 75 (shown in the figure), it stops there and stands by. The sludge attracting device advances as it is.

FIG. 10 shows another embodiment of the guide rail. In the guide rail, a suitable number of horizontal bridge plates 83 are integrated in the longitudinal direction between the rail main bodies 82 similar to those shown in FIG.

FIG. 11 shows the side roller 85 and the flange 8
6 is provided so as to function as a side roller as well as a floating prevention roller. If a roller 87 in an oblique direction is abutted against a corner of the rail body 86 like a phantom line, one roller can have the functions of the side roller and the anti-floating roller.

In FIG. 12, the guide rail 89 is a single H-shaped guide rail, and the side rollers 90 having a floating preventing function are brought into contact with the guide rail 89. It runs on the receiving plate 92.

In FIG. 13, the guide rail 94 is formed by an H-shaped lower plate 95, and a pair of left and right groove type mounting members 96 are mounted on the bottom of the lower plate 75, which are mounted on the anchor 97. The guide rail 94 is fixed by inserting it through the hole of the material 96 and fixing the nut 98 through the hole of the lower plate 95.

FIG. 14 shows a pedestal 10 having a lower lip 100.
The H-shaped rail main body 102 is placed on the first rail 1 to form a guide rail.

In the above embodiment, the orbital filament 56 of FIG. 1 may be replaced. In this case, until now it was necessary to drain the sedimentation basin and replace it, which was a difficult task, but according to the above-described embodiment, as shown in FIG. One end of a new track line is connected to the left end of 56 in the figure, and the track line 56 is indicated by the arrow W.
If you wind it up in the direction of, and set both ends of the new track line on Ikegami as shown in Fig. 1, the replacement work will be completed, so the replacement work is easy without draining water or complicated rope replacement. Become. On the other hand, the orbital line 56
May be fixed by pulling the sheave 57 at a certain height.

The above-described embodiment may be modified into the other aspects in the following points. Although the rotation driving device 53 is installed in a vertical axis, it may be installed in a horizontal (horizontal) axis. On the other hand, when the device 53 is installed on the vertical axis, the wheel 54
Can be installed at a lower level than shown. For example, it may be installed at the same height as or lower than the height of the machine body 22. When the wheel 54 is lowered, it may pass between the guide rails. The running wheel 29 may run directly on the bottom of the pond. The traveling wheels may be of crawler type or rubber tire type. Further, the running wheels are like a drum and may be two wheels or three wheels.

The balancer can be replaced by a spring. Further, a balancer and a spring can be used together. The front and rear scrapers 42 and 43 may be configured only in the front or only in the rear. The floating prevention roller may be provided inside or outside the traveling wheel 29. The advance / retreat control of the sludge attracting device can be performed, for example, by repeating the cycle of advancing the entire stroke once, retracting to a certain intermediate position and advancing several times, and then completely retracting. . This corresponds to the large amount of precipitates on the pit 4 side. The sludge scraping device may be configured to stand up a strut to scrape up scum floating on the water surface. The scraping plate scrapes rightward in FIG. 1 so that the scraping back passes below or above the water surface.
