Description

[Detailed description of the invention] The present invention relates to a dust removal device with a cutter, and in particular, it includes a screen that blocks the garbage flowing in a waterway, a rake arm that scrapes up the blocked garbage along the screen, and a rake arm that scrapes up the clogged garbage along the screen. The present invention relates to a dust removal device equipped with a bushing that pushes out dust onto a receiving surface.

Generally, in waterways such as rivers, there is debris (hereinafter sometimes simply referred to as debris) such as aquatic plants, wood chips, and sludge floating on the water surface.

) may be provided with a dust removal device.

A conventional dust removal device of this type includes a screen that is installed in a waterway in one direction above the water surface, and that blocks the dust flowing in the waterway, and that moves up and down with one end slidingly in contact with the upstream surface of this screen. A raking arm that scrapes up the garbage clogging the screen to the upper end of the screen, a receiving surface provided at the upper end of the screen on which gifts can be placed, and a receiving surface provided at the upper end of the screen (the raised rake arm and the A hooker is provided, which moves the upper corner of the receiving surface with its lower end slidingly in contact with the upper surface, and pushes out the dust on the Rake arm onto the receiving surface, and the rake arm moves the dust 7 blocked by the screen. The structure is such that the scraped garbage is raked up along the screen and then pushed out and transferred from the top of the rake arm onto the four sides with a shovel.

However, with such a configuration, if a part of the debris, such as a piece of debris, gets caught in the gap between the rake arm and the receiving surface, the trapped main shaku etc. will prevent the debris from being pushed out. A situation occurs in which the dust is not moved from the top of the rake arm to the top of the receiving angle due to the pressure applied to the bushing, and there is a viscous defect (see Figure 1).

). The purpose of the present invention is to eliminate the drawbacks of the prior art described above, and to easily cut off pieces of wood that have become caught in the gap between the rake arm and the receiving surface, and to ensure heavy production by transferring with a butcher. There is a shell offering.

The present invention provides a cutter for cutting a piece of wood stuck in the gap between the rake arm and the receiving surface, and avoids the four situations in which the cutter is stopped by the piece of wood.

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2 showing an embodiment of the present invention,
The dust removal device with a cutter has a screen 1 and a rake arm 2.
, a receiving surface 3 , and a bushing 4 .The screen 1 is installed in a waterway (not shown) formed in multiple rows in a river in the vertical direction of the water surface, and is placed above the waterway almost to the water surface. The upper end is fixed to a parallel structure 5.

A rail 6 is laid on this beam 5 in parallel with the longitudinal direction of the screen (front and back direction as viewed in the drawing), and a cart 7 is mounted on this rail so as to be freely movable.

A frame 8 having a substantially curved shape is constructed on top of the cart 7, and one side of this frame 8 forms the receiving surface 3 substantially horizontally, and the other side forms the upper end of the screen and the receiving surface 3. It constitutes a freem guide surface 9 that communicates with one end of the frame.

The rake arm 2 is driven up and down by a lifting drive device such as a playback machine (not shown), and one end of the rake arm 2 is in sliding contact with one surface on the upstream side of the screen 1 when the rake arm 2 is raised or lowered. ing.

Further, the rake arm 2 is in a state of being slightly inclined upward with respect to the horizontal line when it is moving up and down, but when it stops rising, it is in a substantially horizontal state.

The bushing 4 is slidably supported by a guide rail 10 laid above the horizontal rake arm 2 and the receiving surface 3 and parallel to the upper surfaces of these, and is supported by a winch (not shown) or the like. The lower end is slidably brought into contact with the upper surface of the rake arm and the receiving surface by a driving device.

A cutter 11 in the shape of a substantially right triangular column is protruded from the lower end of the extrusion surface 4A of the bushing 4 so that its long side is in sliding contact with the upper surface of the rake arm 2 and the receiving surface 3.
A plurality of cutters 11 are arranged in the longitudinal direction at appropriate intervals.

At a position on the opposite side of the rail 6 of the beam 5 from the screen 1, a belt conveyor 12 for carrying out is laid almost parallel to the rail 6.

The operation of the dust removal device with a cutter according to the above configuration will be explained.

Debris floating on the waterway was removed from Sufunon 1, which was installed in the waterway.
blocked by.

The blocked dirt is raked up along the screen 1 and the screen guide surface 9 by the rising of the rake arm 2.

The rake arm 2 stops at its upper limit position in a substantially horizontal state.

Here, if a piece of wood 13A of the garbage 13 is caught in the gap between the screen 1 and the rake arm 2, then this piece of wood 13A will be stuck in the gap between the rake arm 2 and the receiving surface 3. .

With the piece of wood stuck in this way, when the bushing 4 slides and pushes out the garbage 13, the bushing will push the piece of wood 13 out.
It may collide with A and be stopped.

However, since this bushing 4 has a cutter 11 protruding from the lower end of the extrusion surface 4A, the cutter 11 can cut the wood piece 13
A is cut, so the situation where the wood piece 13A is stopped does not occur.

Therefore, the busher 4 pushes the garbage 13 from above the rake arm 2 onto the receiving surface 3, and further dumps it onto the belt conveyor 12 from above the receiving surface 3.

Thereafter, the trolley 7 is moved and the above-described operation is repeated to remove dust from other waterways, thereby performing dust removal work from the river.

In addition, although the said Example demonstrated the case where the receiving surface 3 was constructed on the traveling trolley|bogie 7, the receiving surface may be comprised by a belt conveyor.

Further, in the embodiment described above, a device for removing dust in a river has been described, but the present invention can also be applied as a device for removing dust from scale deposited in a sedimentation pond of iron-making wastewater.

As explained above, according to the present invention, since the cutter is attached to the bushing, it is possible to cut off part of the debris such as aquatic plants and wood chips that have been caught by the rake arm, and the dirt pushing action of the bushing is always ensured. This allows for continuous removal of dust and automatic removal of stuck wood chips, making work safer, and since overload is not applied to the debris, drive equipment etc. It is possible to suppress failures related to
