DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a dust remover, a sludge scraper,
The present invention relates to a driving device for a dust remover that can easily perform a take-up operation for tensioning an endless chain used in a sand settling machine or the like (hereinafter, simply referred to as a “dust remover”).

[0002]

2. Description of the Related Art In an inflow tank such as a sewage treatment plant or a pumping station, in order to continuously remove refuse flowing from a water channel,
A dust remover is arranged so as to block the water channel, and the inflowing dust is captured by the automatic dust remover, and is lifted and discharged out of the water channel. The drive of this type of dust remover is
A rake is fixed to the endless chain, and a driving sprocket wheel meshed with the endless chain is driven by a driving motor so that the rake moves along the screen.

[0003]

In a conventional driving device for a dust remover, a driving sprocket wheel meshed with an endless chain provided with a rake is driven by a driving motor via a driving roller chain. By the way, the endless chain with rake,
In order to always obtain a predetermined degree of tension, the drive sprocket wheel meshed with the endless chain is adjusted by a take-up device. In this case, if the endless chain with the rake is taken up, the axis of the driving sprocket wheel also moves, so that the tension of the driving roller chain coaxially wound around the driving sprocket wheel can also be adjusted. Required for this,
It is necessary to adjust the installation position of the drive motor, and it takes time and effort to take up an endless chain with a rake.

An object of the present invention is to provide a driving device for a dust remover which can easily perform a take-up operation for tensioning an endless chain simply by moving a driving sprocket wheel.

[0005]

In order to achieve the above-mentioned object, a driving device for a dust remover according to the present invention comprises a driving shaft having a driving sprocket wheel engaged with an endless chain fixed thereto, and a reduction gear fixed to the driving shaft. A drive device driven by a drive motor having a meshing drive gear is slidably supported by a take-up device along a take-up guide of the take-up device, and a reaction force projecting from the drive device is provided. A support roller is brought into contact with the take-up guide to support a reaction force.

[0006]

In the driving device of the dust remover, a driving shaft having a driving sprocket wheel fixed to the endless chain is driven by a driving motor having a driving gear meshed with a reduction gear fixed to the driving shaft. The drive device is slidably supported by the take-up device along the take-up guide of the take-up device, and the reaction force supporting roller protruding from the drive device is brought into contact with the take-up guide to reduce the reaction force. By supporting, the drive motor can be moved to follow the drive shaft to which the drive sprocket wheel meshed with the endless chain is fixed, so that the take-up operation can be easily performed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a dust remover according to an embodiment of the present invention. In the figure, reference numeral 1 denotes a dust remover main body disposed in a water channel W.
The rake L is arranged to be driven along the screen S, and the drive shaft 4 to which the drive sprocket wheel 2 fixedly engaged with the endless chain C provided with the rake L is fixed, and the deceleration fixed to the drive shaft 4 The drive unit 3 is driven by a drive device 3 including a drive motor 31 having a drive gear 32 meshed with a gear 33.

The relationship between the drive sprocket wheel 2 and the drive device 3 is as shown in FIGS. 1 to 5, in which a take-up device 5 is mounted on the upper part of the dust remover body 1, and a take-up screw 7 of the take-up device 5 is connected. By rotating, the take-up bearing 6 is slidably supported along the take-up guide 8, and the drive shaft 4 is rotatably supported by the take-up bearing 6.

The driving device 3 includes a driving motor 31 provided in the main body case 30, a driving gear 32 provided in the main body case 30 and driven by the driving motor 31, and meshed with the driving gear 32. The reduction gear 33 is rotatably supported by a bearing 37 in the main body case 30. The drive shaft 4 penetrates the boss portion of the reduction gear 33,
A hollow shaft structure is formed as a whole by attaching to a wedge. A through hole through which the drive shaft 4 penetrates is also made in the main body case 30 so as to be concentric with the shaft hole of the boss portion of the reduction gear 33.

A bracket 34 protrudes from the outer surface of the main body case 30, and a pin 3
6, and the reaction force support roller 35 is rotatably supported by the pin 36. The projecting direction and the position of the reaction force support roller 35 are determined by the distance between the take-up guides 8 and 8 where the reaction force support roller 35 is parallel when the reduction gear 33 of the drive shaft 4 meshes with the drive gear 32 in the main body case 30. The diameter of the reaction force support roller 35 is determined so that the reaction force support roller 35 is inserted into the allowable error range without much play between the parallel take-up guides 8.

In the present embodiment, a bevel gear is employed as the drive gear 32 and the reduction gear 33, but the same operation can be achieved by using a worm gear.

When driving the dust remover body 1,
When the drive motor 31 is driven, the drive shaft 4 is rotationally driven via the drive gear 32 and the reduction gear 33, and further, the endless chain C provided with the rake L meshed therewith is driven via the drive sprocket wheel 2 in a circulating manner. Is done. At this time, a reaction force is generated in the drive device 3 by the drive of the drive motor 31, and the main body case 30 tends to swing around the drive shaft 4. Since the supported reaction force support roller 35 is inserted so as to be sandwiched between the take-up guides 8, 8, the reaction force generated in the driving device 3 is applied to the take-up guide 8 via the reaction force support roller 30. The endless chain C provided with the rake L is normally driven.

In addition, due to the extension of the endless chain C,
When adjusting the degree of tension, the take-up screw 7 is rotated so that the take-up bearing 6 attached to the tip of the take-up screw 7 is slid along the take-up guide 8. Since the drive shaft 4 is supported by the take-up bearing 6, the drive shaft 4 slides together with the take-up bearing 6 and is adjusted to a predetermined tension. Further, since the driving device 3 is shaft-mounted at the end of the driving shaft 4, the driving device 3 including the reaction force supporting roller 30 slides along the take-up guide 8, and the entire driving device 3 is moved. It will follow.

Although the driving device of the dust remover according to the present invention has been described by taking the dust remover as an example, the structure of the present invention is also applied to a drive device such as a sludge hoisting machine and a sand settling machine having the same mechanism. As a result, the same operation and effect can be obtained.

[0015]

According to the driving apparatus for a dust remover of the present invention, a driving motor provided with a driving shaft having a driving sprocket wheel fixedly engaged with an endless chain and a driving gear engaged with a reduction gear fixed to the driving shaft. The drive device that is driven by the take-up device,
Endless by supporting slidably along the take-up guide of the take-up device and supporting the reaction force by contacting the reaction force support roller protruding from the drive device with the take-up guide. The drive motor can follow the drive shaft to which the drive sprocket wheel that meshes with the chain is fixed, so that take-up work can be performed easily and the reaction force generated in the drive device is supported by the reaction force. It can be supported by a take-up guide via a roller, and the endless chain can be normally driven via a driving sprocket wheel.
