Abstract

(57) [Abstract] [Purpose] The conventional belt cleaner eliminates the problem of poor contact between the belt and the frequent adjustment of the contact condition. No belt conveyor deposit removal device is provided. [Structure] An arm having a substantially right-angled curved portion is rotatably attached to a shaft provided above a head drum of a belt conveyor, and a scraping portion that comes into contact with the belt is provided at a tip of the arm. In addition, a weight is attached near the curved portion of the arm.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an adhering substance removing device for a belt conveyor for transporting powdery or cake-like material (compressed powdery material separated from a slurry by a filter press or the like) which is widely used in the manufacturing industry.

[0002]

[Prior Art]

 When powdered or cake-like material is transported using the belt conveyor, the adhered material is caught from the head of the belt conveyor to the return side, causing troubles such as meandering of the belt conveyor and stopping due to overload. To do. Therefore, in the past, a belt cleaner as shown in Fig. 3 was attached to the return side of the head drum of the belt conveyor.

That is, in FIG. 3, 1 is a belt of a belt conveyor, and 2 is a head drum. A belt cleaner 3 is mounted below the return side of the head drum 2 from below, and this belt cleaner 3 has a scraping portion 6 which is in contact with the belt surface at the tip of an arm 5 connected to a shaft 4. Is configured. In order to insert the scraping portion 6 onto the belt 1, there are a shaft 4 provided with a stopper for fixing the arm 5 and a shaft 4 provided with a spring mechanism for elastically pressing the arm 5.

[0004]

[Problems to be solved by the device]

 However, in the conventional belt cleaner in which only the stopper is provided on the shaft 4, contact with the belt 1 becomes poor due to abrasion of the scraping portion 6 and the like, which causes a problem that the adhered matter cannot be sufficiently scraped off. Further, in the case where the shaft 4 is provided with the spring mechanism, the scraping portion 6 is always pressed against the belt surface, but the entire belt cleaner including the shaft 4 is provided below the return side of the head drum. As a result, an object transported on the belt 1 easily falls and bites into the belt 1, which causes a situation in which the spring mechanism does not fully operate, which causes the same problem. Therefore, conventional belt cleaners require periodic adjustment of contact.

An object of the present invention is to solve the above-mentioned conventional drawbacks and to provide an adhering matter removing device for a belt conveyor that does not require adjustment of the degree of contact with the belt.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides an arm having a curved portion that is rotatably connected to a shaft provided above a head drum of a belt conveyor and has a curved portion that is substantially perpendicular to the middle in a downward direction. A belt conveyor adhering substance removing device is provided with a scraping portion provided at the tip of the arm and in contact with the belt surface of the belt conveyor, and a weight fixedly provided near the curved portion of the arm.

[0007]

[Action]

 The belt conveyor adhering matter removing device of the present invention is configured as described above, and since the whole device is provided above the head drum of the belt conveyor, it may not malfunction due to objects falling from the belt conveyor. Absent. Also, the scraping section is pressed against the belt at an appropriate angle by an arm having a substantially right-angled curved section, and the weight in the vicinity of the curved section of the arm makes it possible to properly follow the belt with almost no adjustment of the contact degree. Contact.

[0008]

【Example】

 FIG. 1 is a perspective view of an embodiment of the present invention, and FIG. 2 is a schematic side view for clearly showing an operating state. The same parts as those in FIG. 3 are designated by the same reference numerals and the description thereof will be omitted.

Reference numeral 7 denotes an arm, which is rotatably connected to a horizontal shaft 8 provided above the head drum 2. The arm 7 has a downwardly bent substantially right angle portion, and a scraping portion 9 that contacts the belt 1 is fixed to the tip of the curved portion. Reference numeral 10 is a weight, which is fixed near the curved portion of the arm 7.

Since the belt conveyor adhering substance removing device of the present invention has the above-described structure, the arm 7 has the shaft 8 as the center of rotation, and the scraping portion 9 is always attached to the belt 1 on the head drum by the weight of the weight 10. When pressed, it acts to remove belt deposits. In addition, there is no possibility of malfunction due to objects falling from the belt.

[0011]

[Effect of the device]

 As described in detail above, the belt conveyor deposit removal device of the present invention makes proper contact with the belt conveyor due to the weight of the weight, so there is no partial contact, and regular maintenance is almost required. do not do.
