The present invention relates to a conveyor belt cleaner. Generally, in a belt conveyor device for conveying sticky materials, etc., a belt cleaner using cemented carbide chips as scraping claws is attached to scrape off residual transported materials adhering to the surface of the conveyor belt. Such belt cleaners can be roughly classified into the following four types. Superalloy chips embedded in part or all of the scraping plate... Utility Model No. 49-27883,

Actual public school 56-13296, special public school 51-48357. In all of the belt cleaners mentioned above,
The upper edge of the scraping plate and the upper edge of the cemented carbide chip are
In the vertical direction, the height is the same or the upper edge of the cemented carbide chip is at a higher position.
In other words, by pressing the cemented carbide chips directly onto the belt surface from the beginning of installation, any deposits on the belt surface can be completely removed using only the cemented carbide chips, even if the mounting angle, dimensions, and means are different. This is what I am trying to do. However, the belt surface is not flat on the return side, there is residual carried material attached to the belt surface that greatly contributes to abrasion of objects in sliding contact, and the wear of the cover layer on the belt surface is on the belt side. The center part of the belt is larger than the edge part, and the difference is large.
3.0 mm, and the scraping plate is worn out by the residual conveyed material, but the center of the belt is the largest in terms of position. Therefore, with the conventional belt cleaner described above, it is difficult to scrape off the residual conveyed material. is likely to occur,
As a result, the remaining conveyed material adheres to the return roller, causing the conveyor belt to shift to one side, causing wear on the belt surface, leading to a shortened belt life. Regarding the above point, as shown in Fig. 9, on the belt line where the wear is large due to the conveyed object a, the belt center part of the conveyor belt b has a large wear, and the center part of the belt support roller C on the return side has a large wear. This can be understood from the fact that the wear increases. The present invention was devised in view of the above points, and it is possible to remove the residual carried substances (adhesive substances) on the surface of the conveyor belt evenly over a long period of time in the width direction of the belt, and also to extend the life of the belt. The main purpose is to provide a conveyor belt cleaner that can. DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below with reference to the drawings. 1 is a belt conveyor device, head pulley 2
(driving pulley) and tail pulley 3 (driven pulley)
A conveyor belt 4 is rotatably suspended, and a conveyor belt cleaner 5 is disposed near the head pulley 2 on the return side, so that the upper edge of a rectangular scraping plate 6 of the conveyor belt cleaner 5 touches the belt surface. The material is pressed against the surface of the belt, thereby scraping off deposits on the belt surface. Specifically, concave grooves 7a corresponding to the overall shape of the metal chip piece 8 are formed in the substrate 7 at a constant interval Δh over the entire width from the upper edge thereof, and the concave grooves 7a
, a metal chip 8 consisting of a plurality of chip pieces 8a
are fitted almost flush and fixed with adhesive (see Fig. 4). Note that the constant interval Δh is required to be at least 3.0 mm because, as stated in the explanation of the prior art, it has been confirmed that the center portion of the belt wears at most 3.0 mm more than the side edge portions of the belt. . In addition to the above-mentioned scraping plate 6, as shown in FIG.
It is also possible to use a scraping plate 12 with a metal chip 8 adhesively fixed to the groove 10a of the bent substrate 10. Note that 13 is an object to be transported, and 14 is a carrier roller on the belt transport side. The wear characteristics of the metal chip 8 and the substrate 10 are shown in the following table.

れた効果を有する。[Front] The conveyor belt cleaner 5 also has a scraping plate 6
Since the upper end edge of the conveyor belt 4 must be constantly pressed against the belt surface of the conveyor belt 4, a pressing mechanism as shown in Figs. 7 and 8 is provided.
A guide member 22 is fixed to the upper and lower portions of the guide member 22. A floating metal fitting 24 is fitted in a guide groove 23 of the guide member 22.
The floating fitting 2 is engaged so as to be movable up and down.
The support member 27 is fixed to the lower end edge of the scraping plate 6, 12 and is supported by the frame 21 through a spring 25 and a height adjustment device 26 (turnbuckle), and is constantly biased by them so as to move upward.
The metal chips 8 are rotatably inserted into the belt surface so that the contact angle of the scraping plates 6, 12 with respect to the belt surface can be adjusted as required. The metal chips 8 are fixed by bolts 28. The height of the metal chips 8 may be constant in the belt width direction, but the height of the belt central portion L1 , which corresponds to the loading portion of the transported goods and has a large amount of deposits, may be two to three times that of the belt side edge portions L2 , L3 (see FIG. 3). In this case, the length L1 is longer than the length L2.
4L2 (= L3 ). Although one conveyor belt cleaner 5 may be provided for one belt conveyor device 1, a plurality of conveyor belt cleaners may be provided in parallel along the belt running direction depending on the nature of the transported material (e.g., adhesion that makes it difficult to remove) and the type of conveyor belt. When the conveyor belt cleaner 5 has one scraping plate, the scraping plate 6A is usually set at an angle of approximately right angle to the belt surface or at a forward inclination angle Θ1 ( Θ1 < 10°).
In addition, when a plurality of scraping plates are arranged along the belt running direction, they are usually fixed in place by
The scraping plate 6B closest to the head pulley 2 is inclined at a substantially right angle or a backward inclination angle Θ 2
It is fixed by. In this case, the forward lean is
The term "tilt backward" refers to the inclination of the upper portion of the scraper plate 6A toward the head pulley 2 with respect to the pivot point O, and the opposite is true for "tilt backward." With the above-mentioned configuration, firstly, the upper end edge of the metal chip 8 is disposed at a position lower than the upper end edge of the base plate 7, so that the base plate 7, which is relatively susceptible to wear, is easily worn.
Only the upper edge of the conveyor belt 4 is pressed against the belt surface of the conveyor belt 4.
The scraper plate 6 (base plate 7) wears according to the strength of the contact with the belt surface, and the upper edge of the scraper plate 6 (base plate 7) conforms to the unevenness of the belt surface relatively soon after installation. As a result, when the belt surface comes into contact with the upper edge of the metal chip 8, the pressure applied by the scraper plate 6 to the belt surface becomes almost constant in the belt width direction, and therefore the scraping effect is also averaged and almost constant in the belt width direction. In particular, in the case of transported materials that are difficult to remove due to adhesion, the remaining transported materials can be almost completely removed by arranging multiple scraper plates as described above. Since the present invention is constructed as described above, the scraper plate is pressed almost uniformly against the belt surface of the conveyor belt in the belt width direction, so that the adhesions on the belt surface can be removed evenly, and the scraper plate is also pressed evenly against the belt surface, so that damage to the conveyor belt (e.g., uneven wear) is reduced, and the life of the conveyor belt as well as the scraper plate is extended, which is an excellent practical effect.
