Abstract

PROBLEM TO BE SOLVED: To keep a belt being not damaged and lengthen the life of the belt by inclining the upper half part of a chip provided on the upper edge of a main cleaner in the reverse direction to the traveling direction of the return side belt, and journalling a rainbow-like finishing cleaner to be rotatable about the shafts in the chord directions of both end parts. SOLUTION: An upper half part 11 of a cemented carbide chip 10 provided on the upper edge of a main cleaner 7 is inclined at an angle of toward the reverse direction of the direction of an arrow A5 of a return belt 5. Shafts in the chord direction of a rainbow-like finishing cleaner 8 are projected on both ends of the rainbowlike finishing cleaner 8, and the rainbow-like finishing cleaner 8 is turned round the shafts to arbitrarily control the height of the shaft at the upper edge from the shaft center. A part of a transported material 12 which has not been separated from a conveyer belt 3 adheres to the lower surface of the return side belt 5 as deposit 17 and travels in the direction of the arrow A5, so that a block-like deposite 18 hard to be scraped off by the next main cleaner 7 is previously scraped off by the upper surface of a plate-like roughing cleaner 6 made of urethane resin.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt conveyor for transporting various materials such as ore grains, clay, cement and foodstuffs on a belt conveyor. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt conveyor cleaner for separating from a belt conveyor.

[0002]

2. Description of the Related Art As a conventional cleaner device of this type, a portion of a super-steel chip at the upper edge of an elastic winding plate is provided on the lower surface of a return belt of a conveyor belt wound between a pair of pulleys separated from each other. There is a device which presses the surface of the return belt to scrape off the substance adhered to the lower surface thereof while the return belt is running.

[0003] This is due to the continuation of the scraping action described above.
The super-steel chip on the upper edge of the elastic scraping plate gradually wears, and the pressure force between the belt and the lower surface of the belt decreases, or the elastic scraping plate elastically deforms in the running direction of the belt. In this case, the pressing force during that time is reduced, and the function of scraping off the adhered material on the lower surface of the belt is reduced.

[0004] This phenomenon is more remarkable as the amount of deposits adhering to the lower surface of the return belt after transporting a highly sticky transport article on the upper surface of the conveyor belt is increased.

Also, due to the nature of this type of conveyor belt, the cross-sectional shape of the belt on the return side facing the running direction usually forms a middle-high rainbow shape, so that the scraping plate is attached to the lower surface of the belt on the return side. The crimping force of the upper edge is weaker in the central part than on the both sides thereof, and there is a tendency that deposits remain in this part.

[0006]

SUMMARY OF THE INVENTION The object of the present invention is to solve the problem that the super-steel chip on the upper edge of the elastic scraping plate is worn as it is used or elastically deforms in the running direction of the return belt. The purpose is to prevent deposits from remaining after scraping the kimono.

Another problem is that even if the vertical cross section of the return belt facing the traveling direction is formed in a rainbow shape, the return belt is uniformly scraped over the entire lower surface thereof, and after the scraping, the adhered matters remain. It is not to be.

Another object is to prevent the upper edge of the scraping plate from damaging the lower surface of the return belt in contact therewith.

[0009]

SUMMARY OF THE INVENTION A cleaner device according to the present invention comprises a plate-like roughing cleaner made of urethane resin, which is close to a lower surface of a return belt of a conveyor belt wound around a pair of pulleys spaced apart from each other. A urethane resin plate-shaped main cleaner provided with a super steel tip and a urethane resin rainbow shaped cleaner are sequentially arranged at intervals along the traveling direction of the return belt, and the upper edge of the main cleaner The upper half of the chip provided at the end is inclined in the direction opposite to the running direction of the return belt, and the rainbow-shaped finishing cleaner is rotatably mounted around the chordal axes at both ends thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a pair of pulleys 1, 2 are provided separately from each other, and the pair of pulleys 1, 2 are provided.
And a belt-like roughing cleaner 6 formed of urethane resin on the lower surface of the return belt 5 of the conveyor belt 3 along the running direction A5 in order to run in the directions of arrows A4 and A5. As shown in FIG. 5, a urethane resin plate-shaped main cleaner 7 having an ultra-steel chip 10 screwed on its upper edge 9 as shown in FIG. 5 and a urethane resin rainbow shaped cleaner 8 are spaced from each other as shown in FIG. ₁ , 1 ₂ are placed apart.

The upper half 11 of the super steel tip 10 provided on the upper edge of the main cleaner 7 is inclined θ in a direction opposite to the direction of arrow A5 of the return belt 5 as shown in FIGS.
Also, as shown in FIGS. 1, 8 and 9, the chordwise shafts 14 of the rainbow shaped cleaner 8 are provided at both ends of the rainbow shaped cleaner 8.
9, the rainbow-shaped finishing cleaner 8 is turned around the shafts 14 and 15 in the direction of arrow A8 as shown in FIG. Is adjusted arbitrarily.

As shown in FIG. 2, the transported object 12 is placed on the transport side belt 4 of the conveyor belt 3 and transported in the direction of arrow A4. It becomes 13.

At this time, a part of the transported object 12 which has not separated from the conveyor belt 3 becomes an adhered substance 17 and adheres to the lower surface of the return belt 5, travels in the direction of arrow A 5, and is moved by the upper surface of the roughing cleaner 6. In order to scrape off with the next main cleaner 7, it is necessary to scrape off the clumps of clumps 18 in advance. At this time, since the plate-shaped roughing cleaner 6 is formed of urethane resin, even if the lower surface of the return belt 5 moves up and down during running and comes into contact with the lower surface, as in the case of the steel plate, the return belt 5 is formed on the return side. The lower surface of the belt 5 is not damaged.

This plate-shaped roughing cleaner 6 is shown in FIGS.
As shown in FIG. 1, the screw 20 is screwed to a substrate 20, the substrate 20 is formed integrally with a shaft 22, the shaft 22 is fixed to an adjusting bracket 19 with a set screw 23, and the adjusting bracket 19 is further mounted on a belt conveyor (not shown). Fixed to the frame.

As shown in FIGS. 5 and 6, the main cleaner 7 has a plurality of plate-like portions 7a, 7b and 7c adjacent to each other and is formed in a rectangular shape as a whole, and a local load is applied to each plate-like portion. In this case, only the plate-shaped portion is deformed to prevent the entire upper edge of the main cleaner from being separated from the lower surface of the return belt 5. In addition, each plate-like portion, 7a, 7
The lower half 24 of the plurality of carbide steel chips 10 is screwed to the upper edges of b and 7c, respectively, and the lower part of the main cleaner 7 is screwed 28 to the shaft 27 via the mounting bracket 26, and the shaft 27 Is screwed 29 to the mounting bracket 33.

As shown in FIG. 2 and FIG.
The deposit 30 still remaining on and adhered to the lower surface of the arrow A
When moving in the five directions, it comes into contact with the inclined upper half portion 11 of the super steel tip 10, flows along the inclined surface, and is separated from the lower surface of the return belt 5.

At this time, when an external force F in the running direction of the return belt 5 is generated on the inclined surface of the chip 10 and the plate-shaped main cleaner 7 is bent into the shape of the chain line 31,
Since a pressure P is generated in a direction perpendicular to the inclined surface,
This pressure P causes the chip 10 to be pressed against the lower surface of the return side belt 5, thereby preventing a gap from being formed between the lower surface and the chip 10.

On the other hand, the upper half of the tip 40 shown in FIG.
Is bent into the shape indicated by the chain line 41, a gap C40 is formed between the upper half portion of the chip 40 and the lower surface of the return belt 5, and a large amount of the deposit 32 may escape therefrom.

Then, even with the main cleaner 7 of the present invention, a very small amount of the deposit 32 remaining on the lower surface of the return belt 5 is scraped off by the next rainbow-shaped finishing cleaner 8. This rainbow shaped cleaner 8 is shown in FIGS.
As shown in the figure, the shafts 14 and 15 in the chord direction are fitted to bearings 34 and 35 at both ends thereof, and a coil spring is stretched between the arm 37 screwed 36 to the bearings 34 and 35 and the bearings 34 and 35. Then, the rainbow-shaped finish cleaner 8 is constantly rotated in the direction of arrow A8 by the elastic force of the coil spring 38, and a force for displacing in the direction of arrow Ah is lifted toward the lower surface of the return side belt 5.

This displacement is, as shown in FIG.
Is proportional to the distance R from the center line of the rainbow-shaped finish cleaner 8 to the upper edge 16 of the rainbow-shaped finish cleaner 8.
Is larger at the center than at both ends.

As shown in FIGS. 8 and 9, the rainbow-shaped finish cleaner 8 is rotated around the shafts 14 and 15 in the direction of arrow A8 by the elastic force of the coil spring 38, so that the center of the upper edge 16 of the rainbow-shaped finish cleaner 8 is obtained. Fig. 1
0, the gap C8 in FIG. 11 is eliminated, and the entire surface of the lower surface of the return side belt 5 is evenly contacted, and the attached matter 32 attached here is removed. If the cleaner 8 is not displaced in the direction of the arrow Ah, the contact state between the upper edge 16 of the rainbow-shaped finish cleaner 8 and the lower surface of the return belt 5 is determined when the cleaner 8 is in the state shown in FIGS. Since the center portion and both end portions have the same height h, the upper edge of the iridescent finish cleaner 8 forms a gap C8 at the center portion with respect to the cross-sectional shape of the return belt 5, as shown in FIG.

[0022]

As described above, the present invention provides a plate-shaped roughing cleaner approaching the lower surface of the return belt of the conveyor belt, a plate-shaped main cleaner having a super-steel tip at the upper edge, and Since the rainbow-shaped finish cleaner that is rotatable about the horizontal axis is sequentially arranged along the traveling direction of the return belt, it is possible to separate the deposits on the return belt in three stages, and to separate it. Can be gradually removed as compared with the case of peeling off all at once.

Therefore, even when the amount of deposits is relatively large, or when lump-like deposits are attached, no excessive force is applied to each cleaner, and each cleaner is strongly applied to the return belt. Since the need for pressing is less than when removing all at once, the belt is not damaged and its life can be extended.

Since the upper half of the super steel tip provided on the upper edge of the main cleaner is inclined in the direction opposite to the running direction of the return belt, when the deposit hits the upper half of the steel tip,
The pressure for pressing the upper half of the chip against the lower surface of the return belt is automatically generated in proportion to the amount of the adhered substance and the adhesive force, so that the chip is not separated from the lower surface of the belt and does not escape the adhered substance.

Since the rainbow-shaped finishing cleaner is provided so as to be rotatable about shafts provided at both ends thereof, even if the cross-sectional shape of the lower surface of the return belt facing the running direction is rainbow-shaped in nature. The upper edge of the rainbow-shaped finish cleaner can be brought into contact with the lower surface thereof evenly over its entire length, so that the deposits on the lower surface can be removed without remaining, thereby providing a clean finish.
