DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple dust remover having a simple structure for setting a relatively small-scale intake port and a water conduit, thereby reducing manufacturing and maintenance costs.

[0002]

2. Description of the Related Art A grid-like screen provided in a headrace, a water intake or the like for capturing dust in flowing water has conventionally been provided with a rake that is raised along a front surface of the screen and dust attached to the screen. There is a full-fledged dust remover that can lift up the dust.

[0003]

However, the conventional dust remover is provided with a rake having a full width of the screen so as to be moved up and down by, for example, a rotary chain or a multiple wire rope. Therefore, there is a problem that the production and maintenance costs have to be increased.

[0004] Therefore, such a large-sized dust remover is not provided in an intake port where the amount of garbage accumulated in a normal state is small.
Although a rake is used for manual dust removal on a regular basis, human labor is also heavy labor without danger, so even a physically strong worker reaches the fatigue limit in 20 to 30 minutes and obtains sufficient dust removal results. It was usual not to be able to. Therefore, a simple dust remover that can be provided at low cost has been desired.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention is to provide a simple dust remover capable of meeting the above-mentioned demands. The present invention provides a simple dust remover which supports a suspension rail horizontally above a screen provided in a water channel. A suspension frame is suspended so as to be movable along the rail, a wire drum is rotated by a driving unit such as a handwheel on the suspension frame, and a wire guide for guiding a wire wound on the wire drum is provided. A rake is provided at the lower end of the pole suspended from the suspension frame into the waterway, the tip of the wire is fastened to the rake, and the wire is wound by rotating the wire drum to screen the rake. , Which can be slid in contact with the front surface of the screen and raised from the waterway, or separated from the front surface of the screen and lowered.

[0006]

The rake provided at the lower end of the pole can be maintained in position by the pole, and can be raised along the front of the screen simply by winding the wire around the drum. For this reason, the structure is simplified, and the manufacturing cost can be greatly reduced.

[0007]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of the simple dust remover, FIG. 2 is a longitudinal sectional view thereof, and FIG. 3 is a plan view thereof. In FIG. 1, reference numeral 1 denotes a screen provided with a large number of crosspieces arranged in parallel at regular intervals in order to catch dust at an intake of a water channel 2 in which water flows in the direction of the arrow. The screen 1 is generally installed at an angle of inclination of 60 to 80 degrees with respect to the horizontal. Reference numeral 3 designates columns 3a and 3b provided on both sides of the water channel 2 and a suspension rail made of I-shaped steel supported horizontally above the screen 1. Reference numeral 4 designates a suspension rail along which the suspension rail 3 can be moved. It is a suspended frame. The suspension frame 4 is provided with a connecting portion 5 having trolley rollers 7 on its upper side so as to be able to roll on the suspension rail 3 with light friction, and a frame body for supporting a pole described later is provided on the back surface. 6 are formed.

Reference numeral 13 denotes a drive unit provided on the suspension frame 4.
A bracket 8 is provided on one side of the suspension frame 4, a handle shaft 10 is supported by a bearing 9 provided on the bracket 8, a chain wheel 11 is fixed to the handle shaft 10, and one end of the handle shaft 10 is provided. Large-diameter ring-shaped handwheel 1
2 is fixed.

Reference numeral 14 denotes a wire drum which is rotatably provided on the suspension frame 4 by supporting a drum shaft 16 with a bearing 15. A chain wheel 17 fixed to one end of the drum shaft 16 and the chain wheel An endless transmission chain 18 is wound around the wheel 11 and the handwheel 12 is rotated to rotate the wire drum 14 via the chain wheel 11, the transmission chain 18, the chain wheel 17, and the drum shaft 16. Connected to.

Reference numeral 20 denotes a crank-shaped wire guide in which a crankshaft 22 is supported by a bearing 21 provided at the lower end of the suspension frame 4. A lever 23 is provided at one end of the crankshaft 22. I have. The wire guide 20 is provided to guide the wire 19 wound around the wire drum 14 by operating around a crankshaft 22 by operating a lever 23 and projecting forward of the wire drum 14.

Reference numeral 30 denotes a rake provided at the lower end of a long pole 31. The rake 30 is provided with rollers 34 capable of rolling on the front surface of the screen 1 and protrudes between the crosspieces of the screen 1. Comb teeth 32 are formed.

The tip of the wire 19 is connected to a stopper 33 provided on the rake 30. Reference numeral 40 denotes an apron extending from the upper end of the screen 1, and 41 denotes an apron 4
9 shows a slab for discharging dust formed on the rear side of a garbage.

In the simple dust remover thus constructed, the rake 30 can be raised along the front surface of the screen 1 by rotating the handwheel 12 and winding the wire 19 around the wire drum 14. For this reason, dust attached to the screen 1 can be hooked on the comb teeth 32 and lifted from the water channel 2 so that the dust can be washed off onto the slab 41. At this time, the frame 6 prevents the pole 31 from falling down sideways. Then, as shown in FIG. 4, the rake 30 is separated from the front surface of the screen 1 by operating the lever 23 and rotating and pushing the wire guide 20 forward, and in this state, the wire drum 14 is lowered and the wire 19 is rotated. And the rake 30 is lowered again into the waterway. Then, the rake 30 can be brought into contact with the front surface of the lower end portion of the screen 1 as shown in FIG. Therefore, by repeatedly moving the rake 30 up and down in this manner, dust attached to the screen 1 can be scooped up by light work.

Further, the rake 30 can be moved horizontally by moving the suspension frame 4 along the suspension rail 3, so that even if the width of the rake 30 is not equal to the width of the screen 1, it can be moved horizontally. If the scooping operation is performed as described above, dust can be sufficiently removed even with a wide screen using a small rake.

In this embodiment, an example is shown in which a handwheel 12 is provided as a drive unit provided on the suspension frame 4. However, instead of such a handle, if a power source can be obtained, a small motor is used as a power source. It is better to provide.

[0016]

As described above, the simple dust remover of the present invention is designed so that the dust can be removed by pulling up the rake, which is maintained in position by the pole, by the wire drum. There are various advantages, such as a reduction in manufacturing and maintenance costs and less failures, without employing a complicated configuration such as a machine.
