  Next, the removal machine 1 which concerns on this invention is demonstrated in detail based on drawing.

  FIG. 1 is a perspective view showing an example of a removal machine 1 according to the present invention, FIG. 2 is a side view of the removal machine 1 shown in FIG. 1, and FIG. 3 is a removal machine 1 shown in FIG. FIG. 4 is a side view showing a main part of the removing machine 1 shown in FIG. 1.

  As shown in FIG. 2, the removing machine 1 according to the present invention is a front side of a substrate 2 formed by molding a synthetic rubber having a required hardness into a strip shape having a length according to the width of the conveyor belt V. On the side edge, a plurality of blades 3 (3, 3,...) That come into contact with the conveyor belt V and scrape deposits are detachably arranged in parallel.

  On the other hand, as shown in FIG. 1, the cylindrical shaft 10 that supports the substrate 2 is positioned at an appropriate position in the longitudinal direction of the transport belt V in the return path, with a required distance from the surface of the transport belt V, and The central axis is arranged in the width direction of the conveyor belt V, and both ends of the shaft 10 are supported on the support base 20 so as to be rotatable.

  As shown in FIG. 4, a rectangular plate-like support plate 30 having a length substantially the same as the length of the substrate 2 is lying on an appropriate position on the peripheral surface of the shaft 10. Are welded so that the support plate 30 has a required inclination angle. A reinforcing member 31 that reinforces the support plate 30 is provided between the back surface of the support plate 30 and the peripheral surface of the shaft 10.

  On the other hand, a joint member 33 for attaching the substrate 2 to the support plate 30 is disposed on the other side edge of the back side of the substrate 2 described above. A band-shaped fixing plate 32 is arranged. Then, nuts 38 (38, 38,...) Are screwed to a plurality of bolts 37 (37, 37,...) Penetrating the fixing plate 32, the substrate 2 and the joint member 33, respectively, so that the fixing plate 32 and the joint member 33 are screwed. The substrate 2 is sandwiched and fixed therebetween.

  In this embodiment, the nut 38 is fixed to the fixed plate 32 by welding. That is, the bolt surface side of the nut 38 and the surface of the fixing plate 32 are fixed by welding in a state where the insertion hole of the nut and the insertion hole of the fixing plate 32 are matched. That is, the welded portion 12 is formed.

  This joint member 33 is formed by inserting a spacer 35 between two plate members 34, 34 to provide an insertion portion 36. The distal end portion of the support plate 30 is inserted into the insertion portion 36, and both plate members 34 are inserted. , 34 and a fixing bolt 39 (39, 39,...) Passing through the support plate 30 are screwed onto nuts 40 (40, 40,...), And the joint member 33 is detachably fixed to the support plate 30. is there. Then, the shaft 10 is rotated so that the tips of the blades 3 (3, 3,...) Arranged side by side on the substrate 2 are brought into contact with the surface of the conveyor belt V, and the blades 3 (3, 3,. By energizing a force that presses the surface of the conveyor belt V against the surface of the conveyor belt V, deposits adhered to the surface of the conveyor belt V are scraped off from the conveyor belt V.

  In such a removing machine 1, since the substrate 2 has an elastic force, it is possible to prevent the surface of the conveyor belt V from wrinkling as much as possible, and in addition, each blade 3 (3, 3,...) Since one substrate 2 is arranged in parallel, even when the conveyor belt V meanders, the adjacent blades 3 (3, 3,...) Are prevented from overlapping each other, and the blade 3 (3, 3, In addition to avoiding brazing of the conveyor belt V due to the overlap of (3,...), The blades are prevented from being damaged.

  As shown in FIGS. 1 to 4, the removing machine 1 includes a substrate 2 formed by molding an elastic material having a required hardness into a belt plate shape having a thickness of about 30 mm and a height of about 90 mm, and the substrate 2. And a support base 20 for supporting the. The length of the substrate 2 is determined in accordance with the width dimension of the conveyor belt V of the belt conveyor on which the removing machine 1 is disposed. A plurality of (in the case of FIG. 3, two) L-shaped blades 3, 3 that are in contact with the surface of the conveyor belt V are arranged in a row on one side edge of the front surface of the substrate 2. 3 and 3 are detachably juxtaposed in a state where the ceiling portion is substantially flush with one side surface of the substrate 2.

  The substrate 2 described above is made of synthetic rubber such as urethane rubber and has a hardness of 70 to 120, preferably about 90. Here, when a synthetic rubber having a hardness of less than 70 is used, the force for bringing the blades 3 and 3 into contact with the conveying belt V is weak, and the ability to remove the deposits attached to the surface of the conveying belt V is reduced. On the other hand, when a synthetic rubber having a hardness exceeding 120 is used, there is a possibility that the blades 3 and 3 are excessively brought into contact with the conveyor belt V and the surface of the conveyor belt V is scratched.

  As shown in FIG. 3, a plurality of pairs (two pairs in FIG. 2) of mounting holes 2 a, 2 a, 2 a, 2 a for mounting the blades 3, 3 are provided near one side edge of the substrate 2. It is opened in such a manner as to penetrate the front and back surfaces of the substrate 2 at predetermined intervals in the longitudinal direction.

  In the present embodiment, the substrate 2 can be attached to a plurality of blades 3 and 3 with bolts and nuts (both legs 3c, 3c and nuts 5 and 5) via a fixing plate 32 which is a substrate attachment member. Eyelets 11 are arranged in the mounting holes 2a, 2a, 2a, 2a formed in the substrate 2, respectively.

  The eyelet 11 has a cylindrical shape and is made of, for example, aluminum. The eyelet 11 may be inserted after forming the mounting holes 2a, 2a, 2a, 2a in the substrate 2, or in the state where the eyelet 11 is inserted into the mold when the substrate 2 is formed. It may be formed.

  In the blade 3 described above, a blade portion 3b formed by molding an alloy having a required hardness into a flat plate shape is fixed to one side surface of a channel-shaped substrate 3a, and the tip of the blade portion 3b is on one side of the substrate 3a. A little protruding from the edge. Legs 3c and 3c are erected on the other side surface of the base material 3a, and threads are engraved on the peripheral surfaces of both leg portions 3c and 3c.

  Then, both leg portions 3c, 3c of the blade 3 are passed through the mounting holes 2a, 2a forming a pair of the substrate 2, and two leg portions 3c, 3c projecting from the both mounting holes 2a, 2a are connected to the strip-shaped metal plate. The blade 3 can be attached to and detached from the substrate 2 by fitting the washer plate 4 formed with holes and fitting the nuts 5 and 5 to the leg portions 3c and 3c protruding from the holes of the washer plate 4. It is installed.

However, the present invention is not limited to this, and the belt conveyor. When the blade 3 is disposed on the return path, a blade 3 is used in which the blade 3b is fixed to the front edge of a rectangular base material with its tip slightly protruding from the base material. As before, a pair of leg portions are erected on the back surface of the blade 3, and when both leg portions are passed through the mounting holes 2a, 2a forming a pair of the substrate 2, the blade portion of the blade is the substrate 2. It protrudes from the side edge.

  The above-described support base 20 adjusts both end portions of a shaft (rod-like member) 10 made of, for example, a metal round pipe to a required rotation angle. Then, the rotation angle of the shaft 10 may be adjusted so that the tilting posture of the substrate 2 fixed to the shaft 10 can be adjusted.

  In this embodiment, the case where the round pipe-shaped shaft 10 is used is shown. However, the present invention is not limited to this. For example, the portion excluding both ends of the shaft 10 is formed in a square pipe shape. It goes without saying.

  Thus, in the removing machine 1 according to the present embodiment, as shown in FIG. 2, the pulley P is rotatably supported by the support shaft arranged in the direction intersecting the vertical direction. An annular belt-like conveying belt V is wound around the pulley P, and the conveying belt V is rotated by the pulley P from above to below as indicated by arrows. At the position below the support shaft of the pulley P, the remover 1 is arranged so that the substrate 2 of the remover 1 faces the width direction of the transport belt V wound around the pulley P. As described above, by adjusting the tilting posture of the substrate 2, each blade 3 attached to the substrate 2 is brought into contact with the surface of the transport belt V with an appropriate load.

  In such a remover 1, since the substrate 2 has a required elastic force, the blade 3 attached to the substrate 2 is prevented from causing wrinkles on the surface of the conveyor belt V, and each blade 3 Is attached to a single substrate 2, so that even if the meandering of the conveyor belt V occurs, the substrate 2 follows the meandering, and the overlapping of adjacent blades 3 is avoided. Damage between each other is prevented.

  As described above, a plurality of mounting holes 2a spaced from each other at a predetermined interval are formed at one end of the substrate 2. A cylindrical eyelet 11 is inserted into each mounting hole 2a.

  As a result, a load is applied to the bolts of the substrate 2 and the swinging of the bolts is suppressed by the eyelets 11, thereby preventing the substrate 2 from being damaged and preventing the legs 3c, 3c from falling off the substrate 2. it can.

  Further, since the nut 38 is welded and fixed to the fixed plate 32, even if a load is applied to the bolt 37 and the nut 38 when the blade 3 is brought into contact with the surface of the conveyor belt V, the nut 38 is not removed from the bolt 37. It can be prevented from falling off.
