Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a simple reciprocating dust remover suitable for small rivers.
[0002]
[Prior art]
Currently, there are chain rotation type, hydraulic arm type, wire rope type, etc., which are generally used for dust removal, but all of them are complex and large in size, too large for small rivers, and costly, There is still manual lifting using a rake.
[0003]
However, manual dust removal work is difficult due to the location of the inlet of the irrigation channel, and it is a remote work that is far from the riverside to the surface with dust, so the work is difficult and workers accidentally fall into the river. Accidents often occurred.
[0004]
[Problems to be solved by the invention]
Therefore, the present invention is intended to provide a simple reciprocating dust remover suitable for small rivers where installation of large machines is not suitable.
[0005]
[Means for Solving the Problems]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. According to the first aspect of the present invention, a U-shaped rail is provided on both sides of the front surface of the screen in parallel with the screen, and slides in the U-shaped rail. A weight shaft that freely moves up and down is provided, a rake is provided on the weight shaft, and a protrusion for preventing drooping of the rake, the tip of which contacts the lower edge of the rail, is provided at the insertion portion of the rail. A reciprocating dust remover characterized in that both ends of the suspension arm are pivotally attached to both sides of the weight shaft.
[0006]
According to a second aspect of the present invention, there is provided a U-shaped rail parallel to the screen on both sides of the front surface of the screen, a check valve-shaped path switching piece at the upper end of the rail, and an upper upper surface of the U-shaped rail. A path switching notch is provided on the upper surface of the lower portion, a weight shaft that is slidably moved up and down is provided in the U-shaped rail, a rake is provided on the weight shaft, and the tip of the U-shaped rail is inserted into the insertion portion of the U-shaped rail. Protrusions for preventing drooping of the rake that come into contact with the lower edge of the rake are provided, and both ends of the U-shaped suspension arm are pivotally attached to both sides of the weight shaft, and the path switching projection that moves in the U-shaped rail on both sides of the suspension arm. A reciprocating dust remover is provided.

DETAILED DESCRIPTION OF THE INVENTION
1 is a front view of one 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 enlarged vertical side view shown.
[0008]
1 to 4, reference numeral 1 denotes an inclined screen, 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, and are attached inward. Reference numeral 3 denotes a weight shaft that is inserted into the U-shaped rails 2 and 2 at both ends, and slidably moves up and down in the U-shaped rail. A rake 4 is provided, and a distal end of the U-shaped rail is inserted into the U-shaped rail. A protrusion 5 for preventing drooping of the rake 4 in contact with the lower edge is provided, and a fan-shaped spacer protrusion 6 is provided on the opposite side of the rake mounting portion. The rake 4 is plate-shaped as shown in FIG. 3, and the tip is comb-shaped.
[0009]
The weight shaft 3 on the opposite side of the rake attachment portion is provided with a pin 7 in a comb-like shape, and the connecting pieces 3a and 3a provided on both sides of the weight shaft 3 are suspended as shown in FIGS. Both ends of the arm 8 are pivotally attached, and the 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, steady-state protruding rods 11, 11 are provided.
[0010]
Since it is configured as described above, when the manual winch 9 is driven, the weight shaft 3 rises via the wire rope 10 and the suspension arm 8.
[0011]
At the time of lifting, since the connecting pieces 3a, 3a are attached to the inflow side from the attachment position of the drooping prevention protrusion 5, the drooping prevention protrusion 5 has a lower edge 2a of the U-shaped rail 2 as shown in FIG. The rake 4 rises while the posture of the rake 4 is regulated substantially horizontally, and the trash caught on the screen 1 is lifted up.
[0012]
During this ascending operation, in this embodiment, the rake 4 has a plate-like shape for easy manufacture, so the running water is also swirled at the same time, so that garbage such as beer cans is discharged to the left in FIG. However, it is received by the pin 7 provided in a comb-teeth shape provided on the opposite side of the rake 4 and rises, and is swept up and discharged together with other garbage. The suspension arm 8 is prevented from shaking left and right by the steady rests 11 and 11 so that the rake 4 is not vibrated, so that the scraped up dust is not shaken off.
[0013]
When the rake 4 rises and reaches the top, the drooping prevention protrusion 5 of the rake 4 is detached 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. Tilt the rake 4 from the horizontal and shake off the trash by impact.
[0014]
After the scraping of the dust is finished, when the reverse rotation preventing claw of the manual winch 7 is removed, the manual winch 7 descends due to the weight of the weight shaft 3.
[0015]
Even when dust is caught on the screen 1 during the lifting of the weight shaft 3, the weight shaft 3 rotates until the protrusion 5 for drooping hits the upper edge 2 b of the U-shaped rail 2. Therefore, the rake 4 slides on the stuck garbage and descends without trouble.
[0016]
Accordingly, the dust caught on the screen 1 can be eliminated by repeatedly raising and lowering the weight shaft 3.
[0017]
7 to 10 show an embodiment of the second invention, and the points different from the embodiment are as follows.
[0018]
That is, path 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 path switching pieces 12 are provided on both upper sides of the U-shaped rails 2 and 2, respectively. 8 is provided with path switching protrusions 13 and 13 that move in the U-shaped rails 2 and 2 on both sides of the rail.
[0019]
According to this structure, when the suspension arm 8 is lifted and the path switching protrusions 13 and 13 push over the path switching piece 12, the suspension arm 8 comes out of the upper notches 2 d and 2 d of the U-shaped rails 2 and 2, and is lowered. The return path slides down on the upper edges 2b, 2b of the U-shaped rails 2, 2, and descends while the rake 4 is reliably raised. When the weight shaft 3 reaches the lowest position, the path switching protrusions 13 and 13 fall from the lower notches 2e and 2e to the inside of the U-shaped rails 2 and 2, and the next path switching protrusions 13 and 13 are again lifted up. Ascend in the U-shaped rails 2 and 2.
[0020]
In the embodiment described above, the case where the wire rope is used as the equipment for the vertical movement is illustrated, but it can also be performed by a shaft, a rack, a chain, or the like.
[0021]
【The invention's effect】
According to the present invention, it is possible to prevent the falling of dust due to a shake at the time of rising, and to prevent the biting of the dust at the time of lowering, thereby realizing a smooth single groove reciprocation of the lifting portion with a simple structure. Therefore, since the structure is simple and can be provided at low cost, it is suitable for small rivers.
