Abstract

PURPOSE:To prevent the scrape remainder and belt damage by radially arranging rubber-made blades, in which ceramic tips are fixed to their tips, on the outer surface of a rotary drum in a cleaner for a belt conveyer for coal, etc., carrying. CONSTITUTION:Three impellers 41 are alignedly arranged in an axis direction on the outer surface of a drum 31. The impeller 41 radially has plural rubber- made blades 43, and a ceramic tip 51 is fixed to the tip of the blade 45. In this constitution, when a conveyer belt 12 moves backward as an arrow, a roller 13 rotates in the arrow direction, the drum 31 too turns in the arrow direction with a belt 39, pulleys 27, 37, and 38, and the tip of the blade 43 slides reversely in a travel direction of the belt 12 on the lower surface of the belt 12. This causes the carried article adhering to the belt is scraped with the tip 51. This constitution enables complete elimination without the damage of the belt.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a belt cleaner for cleaning residues adhering to the belt surface of a belt conveyor used for conveying raw materials such as iron ore, cement, coal, coke, etc.

Conventional technology This type of belt cleaner is a scraper type in which a fixed blade is pressed against the belt to scrape off the residue, and a scraper type in which a blade made of nylon or other material that rotates at high speed is brought into contact with the belt. A rotating brush type that scatters residual materials is known.

Problems to be Solved by the Invention With the scraper type, the mounting position of the blade must be adjusted frequently as the blade wears, and the adjustment work is troublesome. Furthermore, if there are irregularities on either the blade or the belt, scraping remains. Furthermore, if the blade is pressed with too much force or if it is rubbed, the blade may cut the belt.

With the rotating brush type, there is no problem if the conveyed object is smooth, but if the conveyed object is sticky, scraping remains. Another problem is that the bristles are subject to severe wear.

An object of the present invention is to provide a belt cleaner for a belt conveyor that solves the above problems.

Means for Solving the Problems In the belt cleaner for a belt conveyor according to the present invention, a plurality of rubber blades are provided radially on the outer surface of a rotating drum, and ceramic chips are fixed to the tips of the blades.

Function: The belt cleaner for a belt conveyor according to the present invention has the following features:
Since multiple rubber blades are provided radially on the outer surface of the rotating drum, the blades have good adhesion to the belt.
The blades also have a certain amount of elasticity.

Furthermore, since the ceramic chip is fixed to the tip of the blade, the blade is less likely to wear out.

Example Embodiments of the invention will now be described with reference to the drawings.

In the following explanation, "before and after" refers to
The right side is called the front, the left side is called the back, and the left and right are defined as facing forward, and the left and right are the left and right.

As shown in FIG. 2, a power take-off roller 13 is placed above and a belt cleaner 14 is arranged below, sandwiching the lower moving path of the belt 12 of the belt conveyor 11 extending in the front-rear direction, and perpendicular to the moving path. It is located in

Referring to FIG. 1, support shafts 2 are provided at both left and right ends of the roller 13.
1.22 are provided respectively. Both support shafts 21.2
2 are respectively received in bearings 23.24, both bearings 23.
24 are each suspended from the support member 2B by a pair of bolts 25 so as to be adjustable in height.

A drive pulley 27 is fixed to the right end of the right support shaft 22.

The belt cleaner 14 has a rotating drum 31.

Support shafts 32 and 33 are provided at both left and right ends of the drum 31, respectively. Both support shafts 32.33 are bearings 84.3
5, and both bearings 34 and 35 are each received by a pair of bolts 3B in a height-adjustable manner on the support member 2B. A driven pulley 37 is attached to the right end of the right support shaft 33.
is fixed. Further, an idler pulley 38 is disposed at the front midway between the heights of the driving pulley 27 and the driven pulley 37, and a V-belt 39 is hung around these three pulleys 27, 37, and 38.

When the conveyor belt 12 moves backward, the roller 13
is rotated clockwise when viewed from the right, the rotation of the roller 13 is transmitted to the drum 31 by the V-belt 89, and the drum 31 is also rotated clockwise when viewed from the right.

Three impellers 41 are attached to the outer surface of the drum 3 in parallel in the drum axial direction, and four metal annular attachment members 42 are attached so as to sandwich each impeller 41, respectively. Each impeller 41 consists of a plurality of rubber blades 43 arranged radially. Each blade 43 has a plate shape extending in the left-right direction, and has a thick wall portion 44 at its base. Both sides of the thick wall portion 44 are formed inwardly tapered, and the thick wall portions 44 of all the blades 43 constituting one impeller 41 combine to form one cylindrical shape surrounding the drum 31. It constitutes the mounting boss part.

Semicircular grooves 46 are formed on both sides of the thick portion 44, and two adjacent grooves 4B are combined to form one rod insertion hole. Fifteen rectangular flat ceramic chips 51 are fixed to the front end of the image on the side facing the rotation direction of both surfaces of the blade 43 in a row on the left and right so that adjacent chips 51 are in contact with each other.

The mounting member 42 has through holes 52 formed at regular intervals that match the rod insertion holes formed by the grooves 46 of the blades 43. The rod insertion holes formed by the grooves 4B of the blades 43 of the three impellers 41 and the through holes 52 of the four mounting members 42 are arranged so that the corresponding P holes are continuous in the left and right direction. Three impellers 41 and four mounting members 42 are lined up, and a metal round rod 53 is inserted into a continuous hole. Both ends of each round bar 53 and the two mounting members 42 at both left and right ends are joined by welding. Further, as shown in FIG. 5, each mounting member 42 is fixed to the drum 31 by a set screw 54.

Referring to FIG. 3, each blade 43 is provided with two slits 47. The slit 47 reaches the tip of the blade 43 from immediately outside the thick wall portion 44 of the plate-like portion excluding the thick wall portion 44. Furthermore, the 15 chips 51 fixed to one blade 43 are divided into three groups of five each. The plate-shaped portion of the blade 43 is divided into three parts by the slit 47, so that the three divided parts can be bent separately.

When the drum 31 is rotated clockwise as described above, the blades 43 are rotated in the clockwise direction. rotating blade 4
When 3 is facing upwards, the tip of belt 1
The height of the drum 3I is adjusted so that it is pressed against the drum 3I. Since the moving direction of the belt I2 and the moving direction of the blade 43 pressed against the belt 12 are exactly opposite, the remaining material attached to the belt 12 is efficiently stripped off by the tip 51 of the pressed blade 43.

The blade 43 is molded by vulcanization molding of raw rubber, and the chip 5I is baked and bonded during the molding. Feather 43
The molding and baking of the chip 51 can be efficiently performed by molding the two blades 43 at the same time with their tips connected, as shown in FIG. 6, and then cutting the connected portion. It is.

FIG. 7 shows another embodiment. In this embodiment, the blade 6
An engagement protrusion 82 is formed at the base of L, and the engagement protrusion B2
The blade 61 is attached to the drum B3 by welding it to the outer surface of the drum B3 and wrapping it with a metal fitting B4.

Effects of the Invention According to the present invention, since the blades have good adhesion to the belt, no scraping remains even if the belt has unevenness.

In addition, since the blades have appropriate elasticity, the blades do not cut the belt (even if the conveyed material is sticky, no scraping remains).

Furthermore, since the vanes are less susceptible to wear, the mounting of the drum does not require frequent adjustment of its position.
