[0005]

However, the above-mentioned conventional belt cleaner device has the following problems. (1) In the conventional belt cleaner device, the adhered matter such as dust and mud scraped from the conveyor belt by the scraping unit is
The scraping part accumulates on the contact part of the scraping part with the conveyor belt and in the vicinity thereof, and solidifies, so that the scraping efficiency decreases with long-term use, and it is complicated and lacks usability because frequent cleaning is required. Had challenges. (2) In the conventional belt cleaner device, since the scraping portion is made of a rigid material such as metal, the transport belt is damaged due to the pressure contact of the scraping portion and needs to be replaced. There is a problem that the replacement work is required and cost saving and labor saving are lacking. (3) In the conventional belt cleaner device, a tool is used to separate the scraping part from the conveyor belt when the belt cleaner device is not used or to change the contact pressure of the scraping part to the conveyor belt.

The present invention solves the above-mentioned conventional problems, and prevents the deterioration of the transportation efficiency due to the accumulation of the adhered matter scraped off at the contact portion with the transportation belt, and does not damage the transportation belt. A belt cleaner device that can improve cost saving, can be easily pressed against and separated from the conveyor belt, and can be easily changed in contact pressure with the conveyor belt to improve scraping efficiency. The purpose is to provide.

[0007]

In order to achieve the above object, the belt cleaner device of the present invention has the following constitution. The belt cleaner device according to claim 1 of the present invention includes a bearing portion arranged on both sides of the conveyor belt in the width direction and fixed to a frame of the belt conveyor, and both end portions of the bearing portion swingable. A scraping part support that is supported and laid across the width direction of the conveyor belt, a blade-like scraping part that is fixed to the scraping part support and is pressed against the surface of the conveyor belt, and the scraping part support And a swing mechanism section that is disposed at one end of the body and swings the scraping section in the width direction of the conveyor belt via the scraping section support.

With this configuration, the following operation is achieved. (1) By the swinging mechanism part, the scraping part is swung in the width direction of the conveyor belt while being pressed against and sliding against the conveyor belt, so that the efficiency of scraping dust, dirt, and other deposits on the conveyor belt can be improved. Can be improved. (2) By swinging the scraping portion in the width direction of the conveyor belt, it is possible to prevent the scraped deposits from accumulating on the contact portion between the scraping portion and the transport belt. Since it is possible to prevent the scraping efficiency from being reduced due to the accumulation and solidification of the material and to reduce the number of cleaning operations and the amount of work, it is excellent in labor saving. (3) By the swinging mechanism section, the scraping section is swung in the width direction of the conveyor belt while being pressed against the conveyor belt,
The contact pressure of the scraping portion with respect to the conveyor belt can be reduced while maintaining the scraping efficiency, and the cost saving can be improved without damaging the conveyor belt.

The bearing portion may be fixed to a frame or the like provided on both sides of the belt conveyor by screwing or welding with bolts, nuts or the like, or provided by a stand or the like independently of the belt conveyor. Good. The scraping portion support is formed of a long pipe or steel material. The swing width of the scraping portion support is appropriately selected depending on the feed speed of the conveyor belt, the type of the adhered matter adhered to the conveyor belt, and the like, but is preferably 5 mm to 50 mm. By setting the swing width of 5 mm to 50 mm, most of the deposits from the powder to the slurry can be dealt with at a normal frequency. Since the device becomes larger as the swing width becomes larger than 50 mm, it is not preferable to make the swing width extremely large. Further, if the swing width is less than 5 mm, it is necessary to increase the frequency of vibration, and noise is likely to occur, which is not preferable. The scraping portion is formed of a soft material such as rubber or synthetic resin. As a result, the conveyor belt lasts for a long time without being damaged and is excellent in cost saving.
Further, it is preferable that the scraping portion is formed in a plate shape in which a contact portion with the conveyor belt is formed in an acute angle. As a result, the scraping efficiency can be improved, and it is possible to prevent the scraped deposits from being deposited on the contact portion between the scraping portion and the conveyor belt. The contact angle of the scraping portion with respect to the conveyor belt in the scraping direction is preferably set to about 0 ° to 60 ° from the surface of the conveyor belt. If the contact angle is larger than 60 °, the efficiency of scraping the adhering matter is reduced, which is not preferable. The contact angle is 0 °
The closer it is, the more efficiently the scraping efficiency of the adhering matter is improved, but the deformation of the scraping part and the damage of the conveyor belt become more remarkable.

A belt cleaner device according to a second aspect of the present invention is the belt cleaner device according to the first aspect, wherein the scraping portion is fixed to the scraping portion support through a supporting elastic portion. There is.

With this configuration, in addition to the operation obtained by the invention described in claim 1, the following operation is provided. (1) Since the scraping portion can be pressed against the conveyor belt with a suitable elastic force, it is possible to improve the efficiency of scraping the adhering matter adhered to the conveyor belt. (2) Due to the elastic force of the supporting elastic portion, the scraping portion is brought into pressure contact with the conveyor belt at a suitable contact pressure, and even if solidified adhered matter adheres to the conveyor belt surface, it is possible to respond flexibly. The cost saving can be improved without damaging the conveyor belt.

Here, as the supporting elastic portion, a thin plate member made of metal such as iron or stainless steel or synthetic resin is used. As means for connecting and fixing the supporting elastic portion and the scraping portion, and the supporting elastic portion and the scraping portion support, adhesion by an adhesive material, screwing by a screw, or the like is used. In particular, it is preferable that the support elastic portion and the scraping portion are detachably coupled and fixed by a screw or the like.
This makes it possible to easily remove and replace the scraping part from the supporting elastic part when the scraping part becomes worn due to long-term use.

A belt cleaner device according to a third aspect of the present invention is the belt cleaner device according to the first or second aspect, wherein the scraping portion is
