BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust remover installed in waterways, rivers and the like.

[0002]

2. Description of the Related Art Conventionally, as a dust remover for removing dust such as irrigation canals and rivers, for example, a net screen type dust remover, such as Japanese Utility Model Publication No. 59-34583, in which two sprockets are suspended by a chain Are known. On the other hand, the applicant has proposed in Japanese Patent Application Laid-Open No. 4-153404 a new dust remover having superior durability as compared with the net screen type dust remover.

That is, as shown in FIG. 3, reference numeral 1 denotes a substantially cylindrical dust remover main body in which a disc portion 2 and an outer peripheral member 3 are connected by a supporting rod 4. A mesh screen 5 is stretched, and a rake 7 is attached to a plurality of lateral members 6 provided laterally on the outer peripheral member 3. A hollow shaft portion 8 is provided at the center of the disc portion 2, and by supporting the central shaft portion 8 on a bearing 10 provided on a side wall 9 of the water channel A, the dust remover main body 1 can be horizontally rotated. It is provided in. Further, a washing pump 12 is attached to the central shaft portion 8 through a water pipe 11.
The water supply main pipe 13 connected to is loosely inserted, and a pair of injection pipes 14 is connected to the water supply main pipe 13. Then, when the dust remover main body 1 is rotated by the driving force of the motor 15, dust and dirt in the water channel A are captured by the screen 5 and the rake 7, and the screen 5 and the rake 7 are sprayed by the water jetted from the jet pipe 14. Dust, dust, etc. attached to the rake 7 are removed and blown off to the receiving portion 16. At this time, since the bearing 10 and the central shaft portion 8 of the dust remover main body 1 are located in the air on the water passage A, it is possible to prevent rust and the like and improve durability.

[0004]

In the conventional dust remover, the water sucked from the water channel A by the washing pump 12 is jetted from the jet pipe 14 via the water pipe 11 and the water main pipe 13. Therefore, there is a drawback that the pipe distance between the cleaning pump 12 and the injection pipe 14 becomes long and the pipe resistance becomes large. Moreover, since the structure is such that water is fed into the rotating dust remover main body 1, there are problems that many bent portions are formed when the pipe is routed, water pressure is reduced, and sufficient injection is not performed. It was

Therefore, the present invention solves the above problems,
An object of the present invention is to provide a dust remover capable of injecting water from an injection pipe without causing a decrease in water pressure while minimizing the piping distance between the cleaning pump and the injection pipe.

[0006]

According to the present invention, a dust remover main body formed in a substantially cylindrical shape is provided so as to be horizontally rotatable, and dust and the like adhered to the dust remover main body by an injection pipe connected to a cleaning pump. In the dust remover configured to remove, both the cleaning pump and the injection pipe are arranged in the dust remover main body.

[0007]

With the above structure, the cleaning pump for pumping the water in the water channel and the injection pipe for injecting the water from the cleaning pump to the main body of the dust remover are both arranged inside the main body of the dust remover.
Therefore, the pipe distance between the cleaning pump and the injection pipe is restricted inside the dust remover main body, and the water from the water channel is directly pumped to the injection pipe at the shortest distance from the cleaning pump.

[0008]

Embodiments of the present invention will be described below with reference to FIGS. 21 is a dust remover main body formed in a substantially cylindrical shape, which, like the dust remover main body in the conventional example, connects the disc portion 22 and the outer peripheral member 23 by a support rod 24,
A net-like net screen 25 is stretched around the outer periphery of the dust remover main body 21, and a plurality of lateral members 26 are provided laterally on the outer peripheral member 23.
It is configured by mounting a rake 27 on. Reference numeral 28 is a pair of bearings provided on the side wall 29 of the water channel A. A rod-shaped shaft member 30 is arranged and fixed between the bearings 28 over the water passage A. By loosely inserting the shaft member 30 in the center of the disc portion 22, the dust remover main body 21 is The shaft member 30 is provided so as to be horizontally rotatable about the shaft. Further, a driven sprocket 31 is provided on one outer side of the disc portion 22, and a drive chain 33 is suspended between the driven sprocket 31 and a motor 32 with a reduction gear having a gear mechanism.

A cleaning pump 34 has a suction port 35 at its lower end and a discharge pipe 36 on one side. A chain-shaped connecting member 37 is arranged on the upper portion of the washing pump 34,
Connecting tool 37 and suspending tool 38 disposed substantially in the center of the shaft member 30.
The cleaning pump 34 is disposed inside the dust remover main body 21 in a state where the lower side thereof is submerged in the water channel A by connecting with the. Inside the dust remover main body 21, one end of a water feed pipe 39 is connected to the tip of the discharge pipe 36, and the water feed pipe 39 is connected.
The flange portion 40 formed near the upper end of the 39
To be fixed. Further, a substantially T-shaped injection pipe 41 is connected to the other end of the water supply pipe 39 in a state in which the injection pipe 41 is inclined slightly upward with respect to the horizontal, and the injection pipe 41 is horizontally long facing the inner surface of the net screen 25. The slit-shaped injection hole 42 is formed. Incidentally, 43 is a drum cover provided to cover the upper side of the dust remover main body 21, and 44 is a side wall 29 from one side of the dust remover main body 21.
A substantially U-shaped outflow trough portion formed along the reference numeral 45 is a rake guide provided at the bottom of the water channel A.

Next, the operation of the above structure will be described. When the rotation of the motor 32 is transmitted to the driven sprocket 31 via the drive chain 33, the dust remover main body 21 rotates about the shaft member 30 in the scraping direction C and the water channel A in the flow direction B.
Dust, dust, etc. inside are captured by the net screen 25 and the rake 27. Further, the cleaning pump 34 sucks up the water in the water channel A from the suction port 35 and pressure-feeds it to the injection pipe 41 via the discharge pipe 36 and the water supply pipe 39. At this time, since the pipe distance between the cleaning pump 34 and the injection pipe 41 is restricted inside the dust remover main body 21, the water from the water channel A is directly pumped to the injection pipe 41 at the shortest distance from the cleaning pump 34 while the injection hole is being injected. Water is sprayed from 42, which causes net screen 25 and rake 27.
The dust, debris, etc., captured by the blown air are blown off to the outflow trough portion 44. Then, in the outflow trough portion 44, dust, dirt and the like are separated from water by a draining screen or the like (not shown).

As described above, according to the above-described embodiment, the cleaning pump 34 is provided together with the injection pipe 41 inside the dust remover main body 21 having a substantially cylindrical shape, so that the cleaning pump 34 extends to the injection pipe 41. It is possible to minimize the piping distance. That is, the water sucked up by the washing pump 34 is pumped in a state where the pipe resistance is small, and moreover, it is possible to form the bent portion as little as possible when the pipe is routed, so that the water is injected from the injection hole 42 of the injection pipe 41. By injecting with sufficient water pressure, dust, dirt, etc. adhering to the net screen 25 and the rake 27 can be reliably removed.

Further, as an effect of the embodiment, a cleaning pump
By arranging 34 inside the dust remover main body 21 and shortening the piping distance between the cleaning pump 34 and the injection pipe 41, the piping structure between them can be simplified, so space saving and cost reduction can be easily performed. It is possible to plan.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention. For example, the size, shape, size, etc. of the dust remover may be appropriately selected in consideration of the width of the water channel, the water depth, the flow rate, etc. For example, the dust remover body may have a polygonal shape.

[0014]

As described above, according to the present invention, a substantially cylindrical dust remover main body is provided so as to be horizontally rotatable, and is attached to the dust remover main body by an injection pipe connected to a cleaning pump. In a dust remover configured to remove dust and the like, by disposing both the cleaning pump and the injection pipe in the main body of the dust remover, the piping distance between the cleaning pump and the injection pipe is minimized, and It is possible to provide a dust remover that can inject water from an injection pipe without causing a decrease in water pressure.
