  The present invention relates to a belt cleaner device used for scraping off deposits adhering to the surface of a conveyor belt such as a belt conveyor.

  Conventionally, for example, a steel cleaner or the like has used a belt cleaner device to scrape deposits adhering to the surface of a conveyor belt such as a belt conveyor. In general, a belt conveyor wraps a rubber conveyor belt having a predetermined width between a head pulley and a driven pulley in an endless manner, and rotates the head pulley to rotate the belt between both pulleys. Normally, the transported material that is transported on the transport belt is transported on the transport side belt and is discharged on the head pulley side to become a return belt and return to the driven pulley. And deposits under the belt. If this fallen object is left unattended, the work environment will be deteriorated and resources will be lost, so the fallen object will be periodically collected and reused. It takes a lot of labor and money. For this reason, the method of scraping a fallen object in a fixed place using a belt cleaner apparatus and recovering efficiently is employ | adopted.

  Conventionally, various types of belt cleaner devices used in belt conveyors and the like have been adopted. For example, a side frame disposed below the head pulley of the belt conveyor at both sides in the axial direction of the head pulley at intervals wider than the width of the conveying belt hung on the head pulley, and both side frames respectively A fixed mounting member, a rubber spring mounted on each of the pair of mounting members, and a support member (shaft) which is horizontally disposed parallel to the width direction of the transport belt and is held at both ends by the rubber spring. The shaft includes a plurality of cleaner members (scraper members) mounted side by side so as to be arranged in the width direction of the conveyor belt (see Patent Document 1).

And a plurality of scraper members 9 each having a split-type shaft 5 that is attached and fixed to the attachment member 3 in the width direction of the conveyor belt 1 and a tip 7 that is pressed against the surface of the conveyor belt 1. And a cleaner member 11 that is attached to and arranged on the shaft 5 so as to be adjacent to the width direction of the transport belt 1.

  The attachment members 3 are respectively installed on frames (not shown) arranged on both sides of the conveyance belt 1 in the width direction. The mounting member 3 has a plate-like fixed base 13 disposed in the vertical direction (z direction), and a movable base 15 that can move up and down along the fixed base 13. Long holes (not shown) extending in the vertical direction are provided in the fixed base 13 at two locations, and bolts 17 inserted in the vertical positions of the movable base 15 are respectively passed through the long holes and fastened by nuts 19. Thus, the movable base 15 is fixed to the fixed base 13. The bracket 23 at the lower end of the fixed base 13 is attached with an adjustment screw 21 whose upper end is in contact with the lower end surface of the movable base 15. The nut 19 is loosened and the movable base 15 is moved up and down at the upper end of the adjustment screw 21. By moving, the movable base 15 can be adjusted in the vertical direction.

  A rubber spring 25 is attached to the pair of left and right attachment members 3. The rubber spring 25 is fixed to the front surface side of the movable base 15 by a pressing member 27 and is opposed to the width direction of the transport belt 1.

The rubber elastic body 33 is deformed and inserted into the space between the outer side and the outer side.

  The shaft 5 is made of a stainless steel member, and is provided with a central portion shaft 35 to which the cleaner member 11 is attached, and on both sides in the longitudinal direction of the central portion shaft, and one end side (outer end side) is attached to the attachment member 3. In addition to being fixedly attached, the other end side (the opposite inner end side) is divided into a pair of end shafts 37 that abut and engage with both ends of the central shaft 35. That is, the shaft 5 is configured such that the central shaft 35 can be easily attached to and detached from (attached to or removed from) the end shaft 37.

  On one end side of each end shaft 37, a quadrangular projecting member 39 projecting in the axial direction is provided. The protruding members 39 are fitted and inserted into the inner shell members 31 of the rubber springs 25 of the attachment member 3, respectively, so that the shaft 5 is attached and fixed to the attachment member 3.

  In the present embodiment, the shaft 5 is configured to be indirectly attached and fixed to the attachment member 3 via the protruding member 39 provided on one end side of each end shaft 37. The shaft 5 is synonymous with being fixedly attached to the attachment member 3.

  Further, the other end side end surface of each end shaft 37 and the both end surfaces of the central shaft 35 are each formed with a tapered surface obliquely from the upper side to the lower side, as shown in FIG. .

  FIG. 2 shows an example in which the connecting portion between the divided end shaft 37 and the central shaft 35 in this embodiment is fixed and connected by a fixing jig 41 described later. As shown in FIG. 2A, a recess 38 is formed on the end surface on the other end side of the end shaft 37. The concave portion 38 is formed such that a part of one side in the y direction constituting the end surface of the end shaft 37 is cut out, and the three surrounding directions become walls. More preferably, the notch is notched from the surface on the y-direction side perpendicular to the longitudinal direction (x-direction) of the shaft 5 in order to facilitate replacement of the central shaft 35 as will be described later. Is preferred.

  As shown in FIG. 1A, the central shaft 35 is formed so that both ends have a length dimension that is abutted against the other end surface of the end shaft 37. Thereby, the center part shaft 35 can be easily attached to or removed from the end part shaft 37 by moving in the horizontal direction. Further, as shown in FIG. 2A, both end portions of the central shaft 35 are formed so as to form a tapered surface facing the other end surface of the end shaft 37. Further, convex portions 36 are formed on both end surfaces of the central shaft 35.

  Thereby, the convex part 36 formed in the end surface of the center part shaft 35 and the recessed part 38 formed in the other end side end surface of each end part shaft 37 are made into the center part shaft in the other end side end face of the end part shaft 37. The centering and level adjustment are performed at the time of attaching the central shaft 35 to the end shaft 37 simply by fitting together when both end faces of 35 are brought into contact with each other. This eliminates the need for a separate operation for carrying out the process.

  In FIG. 2, only the fixing structure of the end shaft 37 and the central shaft 35 is shown, and the mounting member 3 and the protruding member 39 are omitted. Furthermore, only one side of the fixing structure of the end shaft 37 and the central shaft 35 is shown, and the other side having the same fixing structure is omitted (the same applies to FIGS. 3, 4, and 5 described later). And).

  Thus, since the recessed part 38 is formed in the end surface of the end shaft 37, and the convex part 36 is formed in the end surface of the center part shaft 35, it is with respect to the end shaft 37 attached and fixed to the attachment member 3. Only by attaching the central shaft 35, positioning is performed by fitting the concave and convex portions to each other, so that centering and level adjustment are performed. It is possible to achieve an effect that a separate work is not required. Thereby, it is possible to shorten the mounting work time when the central shaft 35 is mounted to the end shaft 37.

  In the present embodiment, the configuration in which the concave portion 38 is formed on the end surface of the end shaft 37 and the convex portion 36 is formed on the end surface of the central shaft 35 has been described. You may make it form a recessed part in the end surface of 35. FIG. Even with this configuration, the same effects as described above can be obtained.

  In the present invention, the two end shafts 37 and the one central shaft 35 may have a prismatic solid shape or a square pipe-shaped hollow shape. Among these, in the case of using a hollow shape, in FIG. 2 (a), the both end surfaces of the central shaft 35 have a structure in which end face plates formed with convex portions 36 are integrally attached by welding or the like, What is necessary is just to set it as the structure which attached to the other end side end surface of each end part shaft 37 integrally by welding etc. in which the notch for the recessed part 38 formation was formed. Further, in the drawing, the cross section of the central shaft 35 is shown in a hatched state for convenience regardless of whether it is solid or hollow.

  Further, as shown in FIG. 2A, claws 48 extending in the vertical direction (Z direction) protrude from the side surfaces of both end surfaces of the central shaft 35 and the side surfaces of the other end side surfaces of the end shafts 37. Is provided. Further, as shown in FIG. 2B, in the state where the end surface of the central shaft 35 is abutted against and attached to the end surface of the end shaft 37, the connection point between the central shaft 35 and the end shaft 37 is The fixing jig 41 is detachably fixed.

  The fixing jig 41 is configured to hold the outer periphery of the connection point between the central shaft 35 and the end shaft 37 from the outside. As shown in FIGS. 2A and 2B, the fixing jig 41 is formed such that one end sides of the L-shaped member 43 and the crank-like member 45 are connected to each other by a hinge 47, and the other end side can be opened and closed. The other end side of the L-shaped member 43 and the crank-shaped member 45 can be closed to form a rectangular opening. With the central shaft 35 and the end shaft 37 positioned in this opening, the other end is For example, it is formed so that it can be fixed by fastening with a bolt 44 and a nut (not shown) as shown. As a result, the central shaft 35 and the end shaft 37 are firmly fixed, and displacement of the central shaft 35 in the transport direction (y direction) with respect to the end shaft 37 and the transport belt 1 can be prevented.

  The L-shaped member 43 and the crank-shaped member 45 of the fixing jig 41 are formed with two slit-shaped holes 46 each opened as shown in FIG. Thereby, when each end part of the center part shaft 35 and the end part shaft 37 is fixed by the fixing jig 41, the holes 46 are formed on the side surfaces on both ends of the center part shaft 35 and the other end of the end part shaft 37. The central shaft 35 and the end shaft 37 are fixed by the fixing jig 41 so as to be fitted to the claws 48 provided on the side surface of the portion side. Thereby, the shift | offset | difference of the center part shaft 35 and the edge part shaft 37 can further be suppressed.

  Further, as shown in FIG. 1A, the cleaner member 11 is individually provided on the guide cylinder 49 and the guide cylinder 49 fixed to the upper surface of the central shaft 35 with a space in the longitudinal direction. And a scraper member 9.

  Each scraper member 9 has a hard plate-like chip 7 made of a non-elastic material whose tip is pressed against the surface of the conveyor belt 1, for example, a cemented carbide, and a base end portion of the chip 7 via a rubber member 51. The holder portion 53 to be held, the pair of swing shaft portions 55 whose upper ends are fixed to the bottom portion of the holder portion 53 through the central shaft 35 in the vertical direction, and the upper end portions of both swing shaft portions 55 are fixed. At the same time, the guide cover 57 is fitted to the outer periphery of the guide cylinder 49 so as to be swingable in the vertical direction, and is fitted on the outer periphery of each swing shaft portion 55 so that the upper end contacts the inner surface of the upper end of the guide cover 57. A compression spring 59 as an elastic member is arranged so that the lower end is in contact with the upper surface of the central shaft 35.

  Due to the above configuration, each scraper member 9 is constantly urged by a compression spring 59 in a direction in which the chip 7 is compressed onto the surface of the conveyor belt 1. Further, since the swing shaft portion 55 penetrates through the central shaft 35, the scraper member 9 is always positioned so that the scraper member 9 faces the conveyor belt 1 in the direction perpendicular to the action of the rubber spring 25. Is retained. Further, when the chip 7 is strongly pressed in the conveying direction of the conveying belt 1 by a large adhering substance firmly adhered to the surface of the conveying belt 1, the shaft 5 is repelled by the rubber elastic body 33 at the rubber springs 25 at both ends. And the tip of the tip 7 can move in the transport direction to escape temporarily. Thereby, it can suppress that the excessive load is applied to the scraper member 9 containing the chip | tip 7, and the shaft 5, and damage to a belt cleaner apparatus can be prevented.

  Further, since each scraper member 9 is constantly urged by the compression spring 59 in a direction in which the chip 7 is pressed against the surface of the conveyor belt 1, the chip 7 of the scraper member 9 is worn over time. However, some wear of the tip 7 can be urged to the conveying belt 1 without change by the elastic force of the compression spring 59. With such a configuration of the scraper member 9, it is possible to keep the chip 7 pressed against the conveyor belt 1 for each scraper member 9.

  Further, when cleaning is performed in order to remove deposits attached to the tip 7 or when it is desired to replace the tip 7 due to wear, the shaft 5 is divided into a central shaft 35 and an end shaft 37. Therefore, by removing the fixing jig 41, only the central shaft 35 can be easily removed from the end shaft 37. Then, after removing the central shaft 35, the central shaft 35 to which a cleaned or chip-replaced cleaner member prepared in advance is attached and fixed is assembled between the shafts 37 at both ends. As a result, the cleaner member 11 can be easily and easily replaced, and there is no need to remove the entire shaft from the mounting member 3 as in the prior art. Furthermore, since it is only necessary to remove the central shaft 35, the weight of the object to be replaced is reduced and the operation is facilitated as compared with the case of removing the entire conventional shaft.

  Moreover, since the central shaft 35 and the end shaft 37 are simply fixed by a fixing jig 41 with a simple structure, the central shaft 35 can be easily detached and firmly fixed. Can do.

  Next, various modified examples of the connecting portion that connects the central shaft 35 to the end shaft in the first embodiment will be described. 3, 4, and 5 are different in the fixing structure of the end shaft 37 and the central shaft 35 in the first embodiment. Therefore, in the following various modified examples, the same functions and functions as those in the first embodiment are denoted by the same reference numerals, and detailed descriptions thereof are omitted as appropriate.

  First, a first modification of the connecting portion between the end shaft and the center shaft will be described. In the first embodiment, as shown in FIGS. 2A and 2B, a recess 38 formed on the other end surface of the end shaft 37 and a protrusion 36 formed on both end surfaces of the center shaft 35. Are fixed to each other and fixed by a fixing jig 41 from the outside, instead of a configuration of a flange-type fixing jig 41a as shown in FIG. That is, the flange-shaped member 61a and the flange-shaped member 61b as the fixing jig 41a are attached to each other on the other end side surface of the end shaft 37a and both end surfaces of the center shaft 35a by welding or the like.

  More specifically, the flange-like member 61a attached to the end shaft 37a and the flange-like member 61b attached to the central shaft 35a are tapered on the other end side end surface of the end shaft 37a and both end surfaces of the central shaft 35a. As shown in FIG. 3 (b), the opposing surfaces of both flange-like members 61a and 61b come into contact with each other by attaching the end shaft 37a and the central shaft 35a. It is configured to be able to.

  The flange-like members 61a and 61b are formed in a square shape, and holes 63 for inserting bolts 62 are provided at the four corners of the flange-like members 61a and 61b. As a result, the end shaft 37a and the central shaft 35a are brought into contact with each other, the flange-like members 61a and 61b are brought into contact with each other, and a nut 62 (not shown) is tightened and fixed to the hole 63, thereby fixing the end shaft 37a. And the central shaft 35a can be easily and firmly fixed. Further, the central shaft 35a can be easily detached from the end shaft 37a simply by removing the bolt 62 and the nut.

  The shapes of the flange-like members 61a and 61b are not limited to a square shape, and the holes 63 are not necessarily provided at the four corners. Of course, other shapes and different numbers of holes 63 may be used as long as the end shaft 37a and the central shaft 35a can be firmly fixed using the flange-shaped members 61a and 61b.

  Next, the 2nd modification of the connection part of an end part shaft and a center part shaft is demonstrated. In this modification, as shown in FIG. 4, the end shaft 37 b and the central shaft 35 b are fixed by a fixing jig 41 b via a holder 65. In the first embodiment and the first modification shown in FIGS. 2 and 3, the end shafts 37 and 37a and the end surfaces of the central shafts 35 and 35a are formed as tapered surfaces facing each other. In this modification, the other end side end surface of the end shaft 37b and the both end surfaces of the center shaft 35b are each formed in a substantially vertical plane.

  On the end surface of the end shaft 37b, as shown in FIG. 4 (a), a holder 65 having a substantially U-shaped cross section that opens in the y direction when viewed from the x direction is provided by a fixing means such as welding. It is fixedly attached to the end surface of 37b. The holder 65 is inserted with a connecting bolt 66 (to be described later) when the center shaft 35b is fitted and held on the upper and lower holding plates 67 that hold the end of the center shaft 35b. A hole 69 is provided for this purpose. At the end of the central shaft 35b, there is provided a through hole 71 penetrating in the vertical direction at a position corresponding to the hole 69 when fitted to the holder 65.

  As shown in FIG. 4B, the holding plate 67 of the holder 65 is held from above and below by the fixing jig 41b with the end of the central shaft 35b fitted inside the holder 65. . Further, in a state of being held by the fixing jig 41b, the connecting bolt 66 is inserted into the hole 69 of the holding plate 67 and the through hole 71 of the central shaft 35b, and the lower part is tightened with the nut 68, whereby the end shaft 37b. And the central shaft 35b can be firmly held by the fixing jig 41b. In order to suppress the displacement in the y direction of the central shaft 35b, it is preferable to use a pressing bolt 73 for pressing the central shaft 35b.

  Thereby, also in this modification, the end shaft 37b and the center shaft 35b are easily and firmly fixed by the fixing jig 41b via the holder 65, as in the first embodiment and the first modification. can do. Furthermore, it is possible to easily remove the central shaft 35b from the end shaft 37b and the holder 65 only by removing the connecting bolt 66 from the fixing jig 41b.

  Next, a third modification of the connecting portion between the end shaft and the center shaft will be described. As shown in FIG. 5, the present modification is configured such that the end shaft 37c and the central shaft 35c are fixed by a fixing jig 41c via a holder 75, and the second modification is used as a component. And in common. However, as shown in FIG. 5 (a), the holder 75 of the third modified example is formed with a U-shaped recess so that the inner surface holds the end of the center shaft 35c, and the center portion A tapered surface is formed in accordance with the tapered surface of the end surface of the shaft 35c. At this time, since the end of the central shaft 35c can be received by the U-shaped concave portion of the holder 75, a concave portion or a convex portion is formed on the end surface (tapered surface) of the holder 75 and the end surface of the central shaft 35c. Even if the center shaft 35c is held and attached to the holder 75, centering and level adjustment can be performed, and a separate operation for subsequent centering and level adjustment is unnecessary. can do.

  In addition, the holder 75 is provided with a hole 77 through which a connecting bolt 85 described later is inserted in the horizontal direction (y direction) on the side wall of the recess that holds the end of the central shaft 35c. On the other hand, a through-hole 79 that penetrates in the horizontal direction is provided at a position corresponding to the hole 77 of the holder 75 at the end of the central shaft 35c.

  The fixing jig 41c has a plate-like member 81 whose longitudinal direction is the y direction, and a space equivalent to the width of the holder 75 on both sides of the plate-like member 81 in the longitudinal direction (y direction).

  The pair of holding members 83 are configured such that the lower surfaces are fixed to the plate-like member 81, and the side surfaces facing each other can hold the holder 75 as the holding surface 87. In addition, a protrusion 89 is formed on the top of the holding surface 87 so as to protrude toward the holding surface 87 (y-direction side) facing each other, and the interval between the protrusions 89 is narrower than the interval between the holders 75. It is formed as follows.

  When the end portion of the central shaft 35c is placed and held on the holder 75 of the end shaft 37c and then the connecting portion between the holder 75 and the central shaft 35c is fixed by the fixing jig 41c, first, the plate The plate-like member 81 of the fixing jig 41 c is set in the holder 75 in a state where the connecting bolt 85 and the one holding member 83 are removed from the like-like member 81. Next, when the removed holding member 83 is attached to the plate-like member 81 with bolts 82 and nuts 84, both side surfaces of the holder 75 come into contact with the holding surfaces 87 opposed to both the holding members 83.

  As a result, as shown in FIGS. 5A and 5B, after the end of the central shaft 35c is fitted and held inside the recess of the holder 75, the connecting bolt 85 of the holding member 83 of the fixing jig 41c is retained. The connecting bolt 85 is inserted into the hole for insertion, the hole 77 of the holder 75, and the through hole 79 of the central shaft 35c, and the bolt 85 is tightened with a nut (not shown), so that the end shaft 37c and the central shaft are centered. The part shaft 35 c can be firmly fixed by the fixing jig 41 c through the holder 75. In addition, the fixing jig 41c in the present modified example is formed with the protruding portion 89 that projects to the upper position of the concave portion, so that the protruding portion 89 can regulate the displacement and movement of the central shaft 35c in the z direction. it can.

  In addition, when the central shaft 35c is removed from the end shaft 37c and the holder 75 from the state where the end shaft 37c and the central shaft 35c are fixed by the fixing jig 41c via the holder 75, the above procedure is performed. The reverse procedure may be performed. That is, while removing the connecting bolt 85 from the fixing jig 41 c, one holding member 83 of the pair of holding members 83 is removed from the upper surface of the plate-like member 81. Next, the fixing jig 41 c is removed from the holder 75. Thereby, the center part shaft 35c can be removed from the holder 75.

  The second embodiment of the belt cleaner apparatus according to the present invention is, in the third modified example shown in FIGS. 5 (a) and 5 (b), attached and fixed to a pair of left and right end shafts 37c by welding or the like. Instead of the configuration provided with the holder 75 that is configured to hold only the end portion of 35c, the left and right holders 75, 75 in the third modification are extended and connected to the left and right end shafts 37d, 37d. The integrated holder 91 is configured such that the central shaft 35d is accommodated and held inside the integrated holder 91.

  FIG. 8 is an enlarged perspective view of the main part showing the configuration of the end shaft 37d, the holder 91, the central shaft 35d, and the fixing jig 41d on one side in the present embodiment. As shown in FIG. 8 (a), a holder 91 having a concave cross section that is open upward (z direction) is attached between the end shafts 37d and 37d of the present embodiment. Further, a through hole 93 is provided on the lower surface of the holder 91 so as not to interfere with the swing shaft portion 55 of the scraper member 9 penetrating from the central shaft 35d. The number of through-holes 93 should just be formed more than the number of scraper members 9 so that the rocking | fluctuation shaft part 55 of the scraper member 9 may not interfere with the holder 91 (in the figure, since the principal part is expanded, the through-hole 93 is sufficient. Shows only one).

  The configuration and attachment / detachment method of the fixing jig 41d, the attachment / detachment method of the central shaft 35d, the configuration of the end shaft 37d and the configuration of the central shaft 35d are the same as those in the first embodiment and the third modification. Therefore, the description is omitted.

  In FIG. 7, 92 is an intermediate set bolt for fixing the intermediate portion of the central shaft 35 d to the holder 91 and preventing the central shaft 35 d from coming out of the holder 91, and 92 a is an intermediate set bolt 92.

Further, in the scraping work of the adhered matter adhered to the conveyor belt 1, vibration is generated in the cleaner member 11, but since the holder 91 is integrally connected, the belt cleaner device is resistant to vibration. Become.

  In the present embodiment, the fixing jig 41d is the same as the fixing jig 41c of the third modification of the first embodiment as the configuration of the fixing jig. However, the fixing jig of the first embodiment as shown in FIG. 41 may be used.

  In the present embodiment, one central shaft is shown as the configuration of the central shaft 35d. However, in the present embodiment, the holder 91 is integrated with the pair of end shafts 37d and 37d. Although not particularly shown in the figure, the central shaft housed in the holder 91 may be divided into two or more. Thus, even if it is the structure which divided | segmented the center part shaft into two or more, since each divided | segmented center part shaft should just be accommodated in the holder 91 and hold | maintained, each divided | segmented center part shafts are special. There is no need to connect and fix to, and the mounting structure to the holder 91 is easy.

  In addition, after accommodating and holding | maintaining such a divided | segmented center part shaft in the holder 91, both ends were provided according to the magnitude | size of the divided | segmented center part shaft, for example for every divided | segmented center part shaft. It is preferable to fix with the fixing jig 41d using the hole 92a. This is because the divided central shaft is securely fixed. According to such a configuration, the same effects as in the present embodiment can be obtained, and since it is only necessary to replace each divided central shaft, the weight of the central shaft to be replaced is reduced, and the replacement work is easier. become.

  Next, a belt cleaner device according to a third embodiment of the present invention will be described with reference to FIGS. In the present embodiment, elements having the same functions and functions as those in the above embodiments and modifications are given the same reference numerals, and detailed descriptions thereof are omitted as appropriate. explain.

  As shown in FIGS. 9A, 9B, and 10, the present embodiment is divided in the same manner as the first embodiment shown in FIGS. 1A, 1B, 2A, and 2B. A cleaner member 11e of a type in which the tip is brought into contact with the side surface of the conveyor belt is attached to the central shaft 35e, and the pressing force of each scraper member 9e of the cleaner member 11e against the conveyor belt 1 can be individually adjusted. It is a thing.

  That is, as shown in FIG. 9A, the belt cleaner apparatus according to the present embodiment is provided with attachment members 3e disposed on both sides in the width direction of the conveyor belt 1, and both ends attached and fixed to the attachment member 3e. The shaft 5 has a shaft 5 extending in the width direction of the belt 1 and a plurality of scraper members 9e each having a tip 7e pressed against the surface of the transport belt 1, and the shaft along the width direction (x direction) of the transport belt 1 5 and a cleaner member 11e arranged and attached to 5. Therefore, in this embodiment, as shown in FIG. 9 (b), since the position where the belt cleaner device is installed is changed, the configurations of the cleaner member 11e, the mounting member 3e, and the shaft 5 are the same as those of the first embodiment. It is different from the configuration.

  First, the structure of the cleaner member 11e in this embodiment is demonstrated.

  As shown in FIG. 9B, the scraper member 9e in the present embodiment is directed toward the belt surface from the outside (y direction) of the conveyor belt 1 at a position where the conveyor belt 1 is reversed at the position of the head pulley 2. It is installed so that it can be pressed. Specifically, each scraper member 9e is located at a position where the tip end of the tip 7e can be in pressure contact with a slightly lower position along the circumference of the head pulley 2 from one end in the horizontal direction perpendicular to the axial direction of the head pulley 2. Has been placed. This is because this position is an effective range for scraping off the deposits on the surface of the conveyor belt 1.

  The cleaner member 11e in the belt cleaner apparatus of the present embodiment is composed of a plurality of scraper members 9e that are separately attached to a bracket 95 on the upper surface of a central shaft 35e, which will be described later.

  Each scraper member 9e includes an independent tip 7e, a tip holder 99 attached to the bracket 95 of the central shaft 35e so as to be rotatable, while holding and fixing the lower end portion of the tip 7e at the tip end side. , Are provided. The tip holder 99 is attached to the bracket 95 of the central shaft 35e so as to be rotatable by attaching the bracket 101 of the tip holder 99 with a hinge 97 to the bracket 95 of the central shaft 35e. In the belt cleaner device of this embodiment, the tip 7e is made of an elastic material such as hard rubber or hard urethane.

  Further, the lower end side of the tip holder 99 is attached to the central shaft 35e and protrudes from the lower end of the central shaft 35e, and has a long hole opening 103 for inserting a dimension bolt 109 described later. The base end portion 105 is formed.

  On the other hand, the central shaft 35e is provided with a plurality of projecting portions 107 projecting from the lower end in the vertical direction (z direction) corresponding to the position of the base end portion 105 of the chip holder 99. A dimensioning bolt 109 extending in the horizontal direction is provided, and the dimensioning bolt 109 is inserted into the long hole opening 103 of the base end portion 105.

  Further, a compression spring 111 is interposed along the cutting bolt 109 between each projecting portion 107 of the central shaft 35 e and the base end portion 105 of the tip holder 99, and the base end of the tip holder 99 is inserted. The part 105 is pressed by the elastic force of the compression spring 111. As a result, the tip holder 99 is biased by the compression spring 111 so as to be rotated counterclockwise about the hinge 97, and the tip 7e is always pressed against the conveyor belt 1 for each scraper member 9e. ing.

  In particular, in this embodiment, since the tip 7e is made of an elastic material such as hard rubber, the tip of the tip 7e (the contact portion with respect to the conveyance belt 1) is worn by use, and the length of the tip 7e is reduced. However, the compression spring 111 is actuated so that the tip 7e follows the conveyor belt 1 for each scraper member 9e and is urged in the direction of pressing the conveyor belt 1. As a result, even if the tip of the tip 7e of the scraper member 9e is worn, the tip 7e is not separated from the conveying belt 1, and the scraping action of the adhered material is not suddenly greatly reduced. Moreover, if it is in the tolerance | permissible_range of a predetermined use limit, even if the chip | tip 7e is worn out, it can continue using, and the chip | tip 7e can be used effectively. As shown in FIG. 9B, the nut 113 is screwed to the distal end side of the cutting bolt 109 protruding from the base end portion 105 of the chip holder 99, so that the compression spring 111 is extended more than a certain amount. In this case, the base end portion 105 of the tip holder 99 comes into contact with the nut 113, and further extension is restricted, and accordingly, the tip holder 99 can be prevented from turning more than allowable.

  9 and 10, reference numeral 100 denotes a bolt for fixing the chip holder 99 and the chip 7 e, and reference numeral 114 denotes a deposit (dust) scraped off when the transfer belt 1 is scraped off. It is a dust adhesion prevention member for preventing it. Although not shown, a dust adhesion preventing member may be provided on the opposite side so as to sandwich the scraper member 9e.

  Thus, in this embodiment, since it is the cleaner member 11e provided with the scraper member 9e having the chip holder 99 and the chip 7e having the above-described configuration, the chip 7e of the scraper member 9e is always in pressure contact with the conveying belt 1. The posture can be maintained. In addition, since the scraper members 9e of the cleaner member 11e can move independently from each other, deposits attached to the conveyor belt 1 can be efficiently removed.

  Next, the attachment member 3e in this embodiment is demonstrated. In the first embodiment, the attachment member 3e has a shaft in the conveying direction of the conveying belt 1 in order to avoid deposits adhering to the surface of the conveying belt 1 because the tip 7 of the cleaner member 11 is made of an inelastic material. The tip 7e in this embodiment is made of an elastic material such as hard rubber or hard urethane as described above. Therefore, even when the tip of the tip 7e is pressed against the transport belt 1, the stress is relieved by the elastic force of the tip 7e, and an excessive load is not applied to the scraper member 9e including the tip 7e and the shaft 5. The shaft 5 does not need to be rotated.

  Therefore, the attachment member 3e does not need a mechanism for rotating the shaft 5 provided with the cleaner member 11e and the like, and can be attached to a chute (not shown) via the attachment member 3e. Various configurations can be made without limiting the configuration shown in FIG.

  Next, the shaft 5 in the present embodiment will be described. As shown in FIG. 9A, the shaft 5 is divided into a central shaft 35e to which the cleaner member 11e is attached and a pair of end shafts 37e as in the configuration of the first embodiment. Yes.

  One end side of each end shaft 37e is fixedly attached to the mounting member. Further, the other end side is formed in a tapered surface shape, and the same concave portion as that in the first embodiment is formed in the tapered surface. In the present embodiment, since it is not necessary to rotate the shaft 5 as described above, one end of the end shaft 37e is directly attached and fixed to the attachment member 3e. Of course, as in the first embodiment, a protruding member may be provided on one end side of the end shaft 37e, and the protruding member may be fixedly attached to the mounting member 3e.

  As shown in FIG. 9A, the central shaft 35e has both end surfaces formed in a tapered surface, and convex portions are formed on the tapered surface, as in the configuration of the first embodiment. Further, as described above, a plurality of brackets 95 protruding upward (z direction) for attaching to the bracket 101 of the chip holder 99 constituting the scraper member 9e are provided on the upper surface of the central shaft 35e with a space therebetween. Is provided.

  The center shaft 35e is abutted against the end shaft 37e having such a configuration, and is simply fixed by the fixing jig 41e. Thus, strong fixing can be realized, and centering and level adjustment are performed. A separate operation for adjusting the level is not required.

  In the present embodiment, the fixing structure using the fixing jig 41e between the end shaft 37e and the central shaft 35e is not limited to the present configuration, and may be configured in various modifications in the first embodiment. Good.

  Next, a modification of the third embodiment will be described. FIGS. 11A and 11B show a modification of the third embodiment. In this modification, the configuration of the cleaner member is different from the configuration of the third embodiment, and other configurations are the same. Therefore, FIGS. 11A and 11B show the enlarged main part with some parts omitted for easy understanding of the configuration of the present modification. Moreover, about what an effect | action and a function are equivalent to 3rd Embodiment, the same code | symbol is attached | subjected and each detailed description is abbreviate | omitted suitably.

  In the third embodiment, each scraper member 9e constituting the cleaner member 11e is attached to the central shaft 35e by the bracket 95 provided on the central shaft 35e and the chip holder 99 of each scraper member 9e. Instead of the structure in which the bracket 101 is rotatably attached via the hinge 97, as shown in FIG. 11 (b), a scraper member 9f with a sleeve is used.

  Specifically, the scraper member 9f is a rectangular cylindrical sleeve 115 into which the central shaft 35f can be inserted into the base end portion 105f between the bracket 101f of the chip holder 99f of the scraper member 9f and the long hole opening 103f. , A bracket 95f is provided on the upper surface of the sleeve 115, and a protrusion 107f is provided on the lower end of the sleeve 115. Thus, the tip holder 99f can be rotated only by the configuration of the scraper member 9f.

  Further, the internal cross-sectional area of the sleeve 115 is configured to be slightly larger than the external cross-sectional area of the central shaft 35f. Accordingly, as shown in FIG. 11B, when the scraper member 9f is attached to the central shaft 35f, it can be easily attached and unnecessary rattling due to the difference in size can be suppressed. . Further, among the plurality of scraper members 9f, the outer side of the scraper member 9f located at the outermost end comes into contact with the fixing jig 41f, and there is no possibility that the scraper member 9f comes out of the central shaft 35f.

  In FIG. 11, 3f is an attachment member that is arranged on both sides in the width direction of the conveyor belt 1 and attaches the end shaft 37f, 100f is a bolt for fixing the tip holder 99f and the tip 7f, and 114f is It is a dust adhesion preventing member for preventing the adhered matter (dust) that has been scraped off from adhering to the conveying belt 1 during the scraping operation. Although not shown, a dust adhesion preventing member may be provided on the opposite side so as to sandwich the scraper member 9f.

  According to the configuration of this modification, it is possible to achieve the same effect as that of the third embodiment. Further, when replacing the scraper member 9f of the cleaner member 11f, the center shaft 35f is removed from the end shaft 37f, and the desired scraper member 9f may be replaced with the center shaft 35f removed. The scraper member 9f can be easily replaced. Further, in the configuration of the present modification, the scraper member 9f with the sleeve 115 is used, so that the scraper member 9f can be moved freely. Therefore, it is possible to move the position of each scraper member 9f by rotation, and it is not necessary to replace the scraper member 9f with a new one each time.

  Also in this modification, the fixing structure using the fixing jig 41f of the end shaft 37f and the central shaft 35f is not limited to this configuration, and is a configuration of various modifications in the first embodiment. Also good.

  Of course, various modifications can be made without departing from the scope of the present invention.
