DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a front view of an embodiment of the first invention, FIG. 2 is a longitudinal sectional side view thereof, FIG. 3 is an enlarged sectional view taken along line AA of FIG. 2, and FIG. It is an expanded longitudinal side view which shows the relationship between a rail and a weight axis.

In FIGS. 1 to 4, reference numeral 1 denotes a screen provided at an angle, and reference numerals 2 and 2 denote U-shaped rails provided on both sides of the front surface of the screen 1 in parallel with the screen. Numeral 3 denotes a weight shaft having both ends inserted into the U-shaped rails 2 and 2 slidably moving up and down in the U-shaped rails. A rake 4 is provided, and a projection for preventing the rake 4 from drooping at an insertion portion into the U-shaped rail. 5, and a fan-shaped spacer projection 6 is provided on the opposite side of the rake mounting portion. The rake 4 has a plate shape as shown in FIG. 3, and has a comb-shaped tip.

A pin 7 is implanted in a comb-shape on the weight shaft 3 on the side opposite to the rake mounting portion, and connecting pieces 3a provided on both sides of the weight shaft 3 are shown in FIGS. Both ends of such a suspension arm 8 are pivotally connected, and this suspension arm 8 is connected to a manual winch 9 via a wire rope 10. In addition, on both sides of the suspension arm 8,
11 are provided.

With the above configuration, when the manual winch 9 is driven, the weight shaft 3 moves up via the wire rope 10 and the suspension arm 8.

At the time of lifting, the connecting pieces 3a, 3a
Since it is mounted on the inflow side from the mounting position of the hanging prevention protrusion 5, the hanging prevention protrusion 5 comes into contact with the lower edge 2a of the U-shaped rail 2 as shown in FIG. It rises while being regulated and scoops up the trash caught on the screen 1.

During this ascent operation, in this embodiment the rake 4
Since it was made into a plate shape for easy production, running water would also be lifted at the same time, so garbage such as beer cans would be discharged to the left in FIG. Is lifted by being received by the pins 7 provided in a comb-like shape, and is scooped and discharged together with other debris. The suspension arm 8 is prevented from swinging left and right by the steady rests 11, 11, so that no vibration is applied to the rake 4, so that the scraped dust is not shaken off.

When the rake 4 rises and reaches the uppermost part, the projection 5 for preventing the rake 4 from coming off from the lower edge 2a by the notch 2c provided on the lower edge 2a of the U-shaped rail 2 and the weight shaft 3
Is rotated clockwise, the rake 4 is tilted from the horizontal, and dust is shaken off by impact.

After the scraping of the garbage is completed, when the reverse prevention claw of the manual winch 7 is removed, the manual winch 7 descends due to the weight of the weight shaft 3.

When the weight shaft 3 descends, even if dust is caught on the screen 1 during frying, the weight shaft 3 rotates until the hanging prevention projection 5 hits the upper edge 2b of the U-shaped rail 2. Therefore, the rake 4 slides on the trapped garbage and descends without hindrance.

Therefore, dust that has caught on the screen 1 can be eliminated by repeatedly raising and lowering the weight shaft 3.

FIGS. 7 to 10 show an embodiment of the second invention.
The differences from the above embodiment are as follows.

That is, route switching notches 2d and 2e are provided on the upper and lower upper surfaces of the U-shaped rails 2 and 2, respectively, and check valve-shaped route switching pieces 12 are provided on both upper sides of the U-shaped rails 2 and 2, respectively. The other point is that track switching projections 13 and 13 that move inside the U-shaped rails 2 and 2 are provided on both sides of the suspension arm 8.

According to this structure, the suspension arm 8 is raised,
When the path switching projections 13 push and open the path switching piece 12, they come out of the upper notches 2d, 2d of the U-shaped rails 2, 2, and return on descending to the upper edge 2b of the U-shaped rails 2, 2. , 2b and descend while keeping the rake 4 ascended. When the weight shaft 3 reaches the lowermost position, the path switching projections 13, 13 are moved to the lower notch 2e,
2e, it falls inside the U-shaped rails 2, 2, and at the next time of hoisting, the course switching projections 13, 13 rise again inside the U-shaped rails 2, 2.

In the above-described embodiment, the case where the wire rope is used as the equipment for the up-and-down movement is exemplified.

[0021]

According to the present invention, it is possible to prevent dust from falling due to run-out at the time of ascending and prevent the dust from being caught at the time of descending. . Therefore, it can be provided at a low cost with a simple structure, and is suitable for small-scale rivers.
