2. Description of the Related Art Conventionally, on the return side of a conveyor belt,
2. Description of the Related Art A belt cleaner device (hereinafter, referred to as an arrayed scraper type belt cleaner device) in which a plurality of cleaner bodies provided with a scraper having a scraping portion in contact with a belt surface is arranged in a transverse direction of the belt is known. The cleaner body elastically supports the scraper with a rubber-like elastic member, mounts a plurality of cleaner bodies on a rotating shaft, supports the rotating shaft on a fixed bracket, and places the scraper on a belt surface. There is provided an urging means for urging the rotating shaft so as to make it resilient toward. Accordingly, the scraper is elastically urged toward the belt surface by the urging means, and further presses the scraping portion against the belt surface via the elastic deformation of the elastic member. Since the rotating shaft is biased by the biasing means, the scraping portion is always pressed against the belt surface even if the scraping portion of the scraper is worn.

On the other hand, a belt cleaner (hereinafter referred to as a curved scraper type) in which a blade-shaped scraper curved in an arc shape is arranged in the cross direction of the belt, and a scraping portion formed on a curved edge of the scraper is brought into contact with the belt surface. Is known. The scraper is a biasing means for pivotally supporting a rotating shaft extending from both ends to a fixed bracket, and for biasing the rotating shaft so that the scraper stands up and elastically contacts the scraping portion toward the belt surface. It has. Therefore, the scraper is elastically urged toward the belt surface in the rising direction by the urging means, and presses the scraping portion against the belt surface. Since the rotating shaft is biased by the biasing means, the scraping portion is always pressed against the belt surface even if the scraping portion of the scraper is worn.

[0004]

In both the line-type scraper type belt cleaner device and the curved scraper type belt cleaner device, the scraper is elastically urged by the urging means, and the scraper is worn. Even after the cleaning, the scraping portion is always pressed against the belt surface, so that no special maintenance is required.

[0005] However, even after the scraper is worn beyond the allowable range, the scraper is kept pressed against the belt surface by the biasing means. There is a possibility that the scraper may be completely consumed and the scraper may be worn beyond the scraping portion.

In this regard, in the prior art, the necessity of replacement is determined by empirically judging the wear time of the scraping section, stopping the conveyor belt and inspecting the abrasion state of the scraping section of the scraper. Must be checked, and the operation is complicated.

A sleeve 13 fixed to the base end of the arm 12 is externally inserted into the rotating shaft 8, and fixing means 14 such as a set bolt is used. The arm 12 is fixed to the rotating shaft 8 by means of. Therefore, the sleeve 13 is
In contrast, the mounting position can be adjusted axially and circumferentially.

As long as the gauge means 11 detects the distance between the arm 12 and the fixed bracket 9 between the two 12, 9, the gauge means 11 is mounted on the arm 12 in the illustrated embodiment. In addition, a reference member 15 provided on the fixed bracket 9 so as to be able to move forward and backward can face the gauge means 11. In the illustrated example, a reference member 15 is a bolt 17 for screwing a nut 16 fixed to the fixed bracket 9.

When 1 moves in the axial direction, the rotating body 23 rotates around the fulcrum shaft 29 in the angle range indicated by the arrow E in the figure.

The display means 24 includes an identification means 31 such as a scale provided near the free end of the rotating body 23 and a display window 3 for making the identification means 31 visible from outside the casing 19.
2. Preferably, as shown in the figure,
The identification means 31 comprises a color-coded scale, and a display window 32.
Is composed of a slit that allows the scale to be seen only partially, and a transparent plate that closes the slit.

(Operation of the First Embodiment) As shown in FIG. 1, the cleaner 5 including the scraper 4 is supported by the support means 7 by supporting the rotating shaft 8 on the fixed bracket 9. When the rotation urging means is set, the rotation shaft 8 is urged in the direction of the arrow P in the drawing, and the scraping portion 3 of the scraper 4 is pressed against the surface of the conveyor belt 2. In this state, the bolt 17 constituting the reference member 15 is adjusted forward and backward,
The tip of the bolt 17 is connected to the rod 2 of the gauge means 11.
1 is brought into contact with the insertion end 25. At this time, the rotating body 23
Is in the neutral position, and the scale of the identification means 31 visible from the display window 32 indicates that the scraping unit 3 is "not worn".

When the belt conveyor is operated, the remaining deposits on the belt surface are suitably scraped off by the scraping section 3 of the scraper 4 and fall. As described above, when the turning shaft 8 is turned in the direction of the arrow P by the urging means in accordance with the wear of the scraping unit 3, the arm 12 is turned in the direction of the arrow F in the drawing. Then, the rod 21 connected to the reference member 15 is pushed up against the spring 26, and the rotating body 23 is rotated via the conversion means 22.

The identification means 31 of the rotating body 23 has a scale indicating the degree of wear of the scraping section 3 and a scale as a warning for instructing replacement of the scraping section 3 finally. For example, the scale as a warning display is colored red. Therefore, when the wear of the scraping unit 3 progresses and the replacement time comes, the display means 24 gives a warning, so that the operator stops the operation of the belt conveyor, removes the cleaner body 5 and removes the scraper 4 from the scraper 4. You just have to replace 3.

(Second Embodiment of Gauge Means) In the second embodiment shown in FIG. 3, the gauge means 11 includes a casing 19 reinforced by an inner frame 18 and is mounted on the arm 12 by screws 20.

The rack 33 and the pinion 34 are meshed with each other, and the pinion 34 is rotatably supported by a mounting base 35. Therefore, when the rod 21 moves in the axial direction, the linear movement of the rack 33 is converted into the rotation of the pinion 34, and the rotating body 23 is rotated together with the pinion 34.

The display means 24 comprises an indicating needle 36 extending from the rotating body 23, a display window 37 for making the indicating needle 36 visible from the outside of the casing 19, and a scale 38 attached to the display window 37. ing.

(Operation of the Second Embodiment) As described above, when the rotating shaft 8 is rotated in the direction of arrow P by the urging means in accordance with the wear of the scraping section 3, the arm 12 moves to the arrow F shown in the figure. It is turned toward. Then, the rod 21 connected to the reference member 15 is pushed up against the spring 26, and the rotating body 23 is rotated via the conversion means 22, and the display means 24
Is moved along the scale 38 of the display window 37.

The scale 38 indicates the degree of wear of the scraping section 3 and is provided with a scale as a warning for instructing replacement of the scraping section 3 finally. For example, the scale as a warning display is colored red. Therefore, when the wear of the scraping section 3 progresses and the replacement time comes, the pointer 36 points to the warning scale, and the operator stops the operation of the belt conveyor, removes the cleaner body 5 and scrapes the scraper 4. What is necessary is just to replace the taking part 3.
