Further, a chute 6 is provided below the return path of the belt 7 to collect water after washing the belt 7 and scattered materials separated from the conveying surface of the belt 7. Inside the chute 6, a chute washing nozzle 20 for jetting water to the inclined inner bottom surface and discharging the scattered matter accumulated on the inner bottom surface to the outside is provided.

[0011]

However, in the conventional belt cleaning device, the scraping member 15 of the belt cleaner 1 is used.
Since the scattered material that could not be peeled off is washed away with the water jetted from the belt cleaning nozzle 2, a large amount of water is used for cleaning, and a large-capacity wastewater treatment facility is required.

The present invention has been made in view of the above circumstances, and has as its object to provide a belt cleaning device capable of efficiently cleaning a belt of a conveyor device.

[0013]

In order to achieve the above object, a belt cleaning device according to the present invention comprises a scraping member disposed on a return-side moving path of a belt and abutting over the entire width of a belt conveying surface; A pressing unit that presses the member against the conveying surface of the belt, and a cleaner that is disposed downstream of the scraping member in the belt moving direction and abuts over the entire width of the conveying surface of the belt, and the tip of the belt is attached to the scraping member. A hole that opens toward the transport surface is formed, and a water supply unit is connected to the base end of the hole.

In the belt cleaning device according to the present invention, the water fed from the water supply means is guided from the hole of the scraping member to the conveying surface of the belt to moisten the conveying surface, and the belt cleaner is cleaned by the subsequent cleaner. Wipe the transfer surface.

[0015]

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

FIGS. 1 to 4 show an embodiment of a belt cleaning apparatus according to the present invention, in which the same reference numerals as in FIGS. 5 to 7 denote the same components.

This belt cleaning device includes a scraping member 21 which is arranged on a return side movement path of the belt 7 at a head end portion of the conveyor device and abuts over the entire conveying surface of the belt 7. A pressing means 22 for pressing the conveying surface of the belt 7, a water feeding means 23 for supplying water to the scraping member 21, and a pressing means 22 disposed downstream of the scraping member 21 in the moving direction of the belt 7 and covering the entire conveying surface of the belt 7. And a cleaner 24 in contact therewith.

The pressing means 22 is pivotally supported by a bracket 9 provided below the head pulley 8 via a bearing 10 and extends in the width direction of the belt 7, and extends in the width direction of the belt 7 and is fixed to the frame 11. The mounting seat 12, a plurality of cushioning members 13 mounted on the mounting seat 12 so as to be arranged in a line in the width direction of the belt 7, and a base end portion extending in a substantially tangential direction of the head pulley 8 and a base end thereof being mounted on the buffering member 13. A plurality of support arms 14, a lever 16 whose base end is fixed to the frame 11 and whose front end protrudes forward of the conveyor, and which is screwed to the bracket 9 so that the front end contacts the lever 16 from below. It is constituted by an adjustment bolt 17.

The scraping members 21 are provided for the respective cushioning members 13 and are mounted on the distal ends of the support arms 14 so as to be arranged in a line in the width direction of the belt 7. In the portion, a hole 25 opening from the back surface (opposite surface facing the belt 7) toward the belt 7 is provided.
A groove 26 is formed in the surface of the scraping member 21 facing the belt 7 so as to be continuous with the left and right holes 25.

The water supply means 23 is provided along the frame 11 and has a base end connected to a water supply source such as a pump (not shown). And a flexible tube 28 connected to the base end of the hole 25 of the scraping member 21.

In the belt cleaning device shown in FIGS.
When the water supply source is operated when the belt 7 rotates, the water supplied from the water supply source is supplied to the hole 25 of the scraping member 21 through the water supply pipe 27 and the flexible pipe 28, and from the hole 25 The jetted water, and the water flowing from the hole 25 to the groove 26,
The transfer surface of the portion of the belt 7 that is wound around the head pulley 8 and the splinters adhering to the transfer surface are moistened so that the splinters are easily separated from the belt 7 transfer surface.

As a result, the scraps containing water are easily separated from the belt 7 by the scraping member 21 pressed against the belt 7 conveying surface by the elastic force of the support arm 14 of the pressing means 22.

Further, the remaining dust and water on the conveyor surface of the belt 7 are wiped off by the cleaner 24 at the subsequent stage.

Further, when the adjustment bolt 17 of the pressing means 22 is tightened or loosened to change the amount of protrusion of the adjustment bolt 17 with respect to the bracket 9, the belt 7
The pressing force of the scraping member 15 against the transport surface is adjusted.

As described above, in the belt cleaning device shown in FIGS. 1 to 4, the water supplied to the scraping member 21 by the water supply means 23 is guided from the hole 25 of the scraping member 21 to the belt 7 conveying surface. By moistening the transfer surface, the peeling of the scattered material is promoted.
Since the belt 7 transport surface is wiped, the amount of water used to clean the belt 7 can be reduced, the belt 7 of the conveyor device can be efficiently cleaned, and a large-capacity wastewater treatment facility is required. And not.

It should be noted that the belt cleaning device of the present invention is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the spirit of the present invention.

[0027]

As described above, according to the belt cleaning device of the present invention, the following various excellent effects can be obtained.

(1) A hole is formed in the scraping member, which is disposed on the return-side movement path of the belt and abuts over the entire width of the belt conveying surface, with a hole having a tip end opening toward the belt conveying surface. Since the fed water is guided from the hole of the scraping member to the conveying surface of the belt to moisten the conveying surface, the scraping member can easily peel off the spatter from the belt.

(2) Therefore, it is possible to reduce the amount of water used for cleaning the belt, eliminate the need for a large-capacity wastewater treatment facility, and improve the belt cleaning efficiency of the conveyor device. The size can be reduced as compared with the conventional belt cleaning device.
