JP3607876B2 - Simple dust remover - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a simple dust removing device that removes algae, grass, dead branches, dust, and the like caught on a screen installed in a water channel without using human hands.
[0002]
[Prior art]
Dust and the like caught on the screen of the waterway are removed by hand manually using a rake or the like.
[0003]
[Problems to be solved by the invention]
Dead branches and the like are bulky and time-consuming to process, and depending on the type of dust, if they gather in large quantities, they may become heavy and difficult to discharge.
It is an object of the present invention to provide a simple dust removing device that can be installed in connection with a water channel to easily remove dust and the like caught on a screen without depending on human hands.
[0004]
[Means for Solving the Problems]
The simple dust removing apparatus according to the present invention installs a screen across a water channel. A frame is established with a portion of the frame straddling directly above the screen position of the channel. A hoist is installed on the frame so as to be movable forward and backward with respect to the screen. A bucket is tilted and suspended on the hoist so as to be movable up and down with respect to the surface of the screen. And the wall which can be undulated with respect to the board | substrate is provided in the inclination direction lower end of this bucket.
[0005]
The screen may be installed directly across the water channel, but is usually installed in a tub interposed in the water channel for the purpose of dust removal or the like. The installation angle may be parallel to the cross section of the waterway,
Generally, the lower part is directed to the upstream side and the upper part is directed to the downstream side, which is convenient for raising dust and the like to the upper layer.
[0006]
A guide rail is installed on the frame, and the hoist is guided to move by the guide rail, and reciprocates between a position directly above the screen and a position directly above the place where dust and the like are discharged.
[0007]
The bucket is tilted and hung up and down by a hoist with a wire or the like. Although the tilting method may be appropriate, when the bucket has one or more walls rising from the outer peripheral edge of the substrate, a wire is connected to the outer surface of the one wall. As a result, the bucket is suspended from the wire in an inclined state in which the one wall is at the upper position and the opposite wall is at the lower position.
[0008]
This opposing wall is a wall that can be raised and lowered. Convenient for scavenging dust. This wall is usually configured by connecting the wall to the substrate with a hinge. When the bucket is hung down with the wall facing down, the free end of the wall hits the screen, and dust or the like that is caught on the screen as it descends along the screen is scooped into the bucket. When I finish scooping, I will raise a wall. Thereby, dust etc. are stored in the bucket.
[0009]
In order to undulate the wall, it is only necessary to connect a wire to the free end of the wall and pull or loosen the wire on the ground. In the state where the bucket is in contact with the screen, no matter how much the wire is loosened, the free wall does not swing any more because its free end hits the screen.
[0010]
The hoist is activated with the raised wall raised to lift the bucket, and then the hoist is moved along the frame. When you come to the discharge site, suspend the bucket and lay down the wall, and dust etc. will be discharged to the discharge site.
[0011]
The screen may be installed in a tub interposed in the water channel.
In this way, the cross section of the water channel becomes wider, a large screen can be installed, dust can be collected on the wide surface of the screen, and the size of the dust removing device can be increased.
[0012]
The bucket may be composed of a frame member and a mesh.
In this case, since moisture flows out through the mesh, the weight is reduced and an extra load is not applied to the drive system of the hoist.
[0013]
The rolling wall undulation may be controlled by an electric motor and a limit switch.
This saves labor because the wall is raised and lowered by button operation.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
1 is a water channel and 2 is a screen installed across the water channel 1. 3 is a frame, and a part of the frame is set up directly across the screen 2 position of the water channel 1. A hoist 4 is installed on the frame 3 so as to be able to advance and retreat directly above the screen 2. The bucket 5 is tilted and suspended on the hoist 4 so as to be movable up and down with respect to the surface of the screen 2.
In the illustrated example, a wire 31 is connected to a frame 5 b attached to the end wall 5 a of the bucket 5.
[0015]
Then, a wall 7 that can be raised and lowered with respect to the substrate 6 is provided at the lower end in the inclination direction of the bucket 5. The wall 7 is connected to the substrate 6 via a hinge 32. One end of the rope 34 is attached to the attachment portion 33 of the free end of the wall 7 and the other end is wound around the drum 35 installed on the substrate 6. By rotating the drum 35 forward and backward, the wire 34 is wound up and sent out, and the wall 7 is raised and lowered. As can be seen in FIG. 4, the state that has occurred is a two-dot chain line state, and the faced state is a solid line state.
[0016]
When it is found that a large amount of dust or the like is caught on the screen 2, the hoist 4 is moved along the frame 3 and stopped when it comes directly above the screen 2. Here, the hoist 4 is activated and the bucket 5 is lowered. The wall 7 of the bucket 5 is turned down.
[0017]
When the bucket 5 descends, the free edge of the wall 7 hits the screen 2. When the bucket 5 is further lowered, the whirling wall 7 descends on the screen 2 while scrubbing dust and the like caught on the screen 2. When the dust or the like is swallowed onto the substrate 6 of the bucket 5, the whirling wall 7 is raised to enclose the dust and the hoist 4 is reversed to raise the bucket 5. Next, the hoist 4 is moved horizontally, and when it reaches the discharge position, the hoist 4 is rotated forward to lower the bucket 5 and the wall 7 is turned down to discharge dust and the like.
[0018]
The screen 2 is installed in a raft 11 interposed in the water channel 1.
In this case, the cross section of the water channel 1 becomes wide, the screen 2 can be enlarged, dust can be collected on the wide surface of the screen 2, and the dust removing device can be enlarged.
[0019]
The bucket 5 includes a frame member 12 and a mesh 13.
In this case, since moisture flows out through the mesh 13, the weight is reduced, and an extra load is not applied to the drive system of the hoist 4.
[0020]
The swinging of the wall 7 is controlled by the electric motor 21 and a pair of limit switches 22 and 23 that cooperate with each other.
In this case, since the wall 7 is raised and lowered by a button operation, labor can be saved.
The limit switches 22 and 23 may be installed in any suitable place. In the illustrated example, the limit switch 22 is installed at one free end of the turning wall 7, and the limit switch 23 is installed on the upper edge surface of the side wall 5 'of the bucket 5. Is done. Depending on the installation location of the limit switch 23, the side wall 5 'can be omitted.
[0021]
【The invention's effect】
According to the present invention, a screen is installed across a water channel, and a frame is established by partially extending the screen directly above the screen position of the water channel, and a hoist is attached to the frame directly above the screen. Since the bucket is tilted and suspended on the hoist so that it can be moved up and down relative to the screen surface, and a wall that can be raised and lowered with respect to the substrate is provided at the lower end in the inclination direction of the bucket. In addition, dust caught on the screen can be easily removed.
[0022]
According to the second aspect, the cross section of the water channel can be widened, the screen can be enlarged, dust can be collected on the wide surface of the screen, and the dust removing device can be enlarged.
[0023]
According to the third aspect of the present invention, since the bucket is composed of a frame member and a mesh, moisture flows out through the mesh, the weight is reduced, and an extra load is not applied to the drive system of the hoist.
[0024]
According to the fourth aspect, the swinging of the wall is controlled by an electric motor and a limit switch, so that the wall can be raised and lowered by operating a button, and labor can be saved.
