JPS6077017A - Belt cleaner for belt conveyer - Google Patents

Abstract

PURPOSE:To provide a compact belt cleaner with improved performance and safety by incorporating a scraper unit, having an antiwear hard scraper mounted to be reversibly slanted, in a support bed vertically movably through a guide holding removably said scraper unit. CONSTITUTION:A scraper unit A is inserted below a conveyer belt and a scraper 2 is temporarily suspended to contact closely the belt. A bar 11 of a guide head B having a support bed C attached is fitted in a socket 9 of a support plate 5 and the angle of the support bed C is adjusted to fasten 10 the lever 11. Next, the support bed C is secured fixedly to a frame body and the tension of a spring 19 is adjusted to adjust the abutting force of the scraper 2. The scraper 2 is slanted by the expansion and contraction of a spring 6 in the travelling of the belt and returned to the original position by the force of the spring 6 at the stoppage of the belt. The wear of the scraper 2 is adjusted by the spring 19. Thus, the compact belt cleaner with improved safety and performance is provided.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a belt cleaner that cleans a conveyor belt by using belt running force with multiple rows of abrasive hard scrapers.

Cleaning of the belt is carried out on the return side of the conveyor belt 22 between the head pulley 23 and the pend pulley 24.
Gradual cleaning efficiency is highest if the cleaning is carried out at a conveyor, and the scraped material can easily be transferred to the next conveyor, so there is no need for reprocessing.However, this position is difficult due to the complicated conveyor frame Therefore, it is extremely difficult to install a belt cleaner with multiple rows of belt cleaners.For this reason, a single-row type cleaner has been used in the past, but the cleaning effect is extremely poor compared to the double-row type. There is a strong demand for double row type.

The use of a double row belt cleaner in this position has been available for many years and there is no satisfactory belt cleaner available.

In particular, when cleaning the belt with a scraper made of wear-resistant hard material, the scraper 2 is tilted slightly in the direction of movement of the belt 22 to prevent severe damage to the belt 22 and protect the cleaner from vibrations and shocks. A slightly thick plate with a thickness of 2 to 3 mm is used for longevity reasons, but once the plate thickness reaches this level, the scraper itself cannot be tilted, so conventionally the scraper and its attachment were made using rubber or a thin plate at the joint of the plate. Although a spring is used, rubber is not strong enough, and plate springs are thin and prone to corrosion and breakage.
J For wide conveyors, scraper holder 1 or belt 22
Since the scraper holders 1 are bent or broken by the regular force of the scraper holder 1, it is necessary to connect multiple rows of scraper holders 1 to each other.In this case, the scraper holders 1 must be connected so that they can each operate individually. It won't happen.

In addition, since m M of the conveyor frame is generally not constant,
When installing the cleaner, it is necessary to freely widen or expand the dimensions.

The object of the present invention is to solve the above-mentioned problems and provide a compact, high-performance, and highly safe multi-row belt cleaner.

The configuration of this invention will be explained in detail.

This invention consists of eight scraper units (8 scraper units) consisting of a scraper unit A, a kite head B, and a support stand C. A scraper holder 1 is pivotally supported on a support tH1x5. The pins 4 at both ends of the two rows of scraper holters 1 are pivotally supported on support plates 5 on both sides, one end of the spring B fitted to each pin 4 is hooked to the pin 4, and the other end is attached to the support plate 5.
The Nubri tin ring 6, which is used as a hook, is easily pulled back and one side loosens.

This operation works in the same way whether the tilting direction is forward or backward. The two rows of scraper holders 1 are connected to each other by a scraper plate 7 and a pin joint 8 so that they can be tilted back individually.

A socket 9 is provided on the support Fi5. The guide head B has a rectangular head 12 at the tip of a bar 11, a kite piece 13, and a bolt 6 in the center. The kite head ÷ is fitted into the socket 9 of the support plate 5 and can be freely put in and taken out, rotated and fixed. The support stand C supports the scraper unit A. A side plate 14 having several kite head movement openings and two pieces of shapes 12 are pushed through the movement openings, loosely fitted onto the kite scrap 18, and supported by springs 19. A bolt 20 is rotatably attached to the bottom & 17, and the head 12 and spring 19 are attached via a nut 21, which improves the quality of the scraper bolt 1 and the spring 1.
The tension of 9 is reduced by 1+'d. Spring 19 is always on the belt conveyor's head pulley 23.
and the belt 22 between the bend pulley 24. To install it, first disassemble the Bell F cleaner into Nuclepa unit A and support stand C with kite head B still attached. At the same time, scraper unit A is moved to conveyor belt 22.
Insert it under the belt 22 and temporarily suspend it with the crane 2 tightly attached to the belt 22. Support the bar 11 of the kite head B with the support C attached from the outside of the conveyor frame &5
9f), adjust the angle of the support base C, and tighten the bar 11 with the set bolt 10. After fixing the support base to the frame, when the bolt is turned to loosen the nut 21 holding the spring 19, the spring 19 or the scraper 2 is automatically pushed onto the belt 22. Remove the temporary suspension at this point.

When the conveyor starts and the belt 22 runs normally, the belt 22
The invention is as described above, in which the scraper 2 is slightly tilted in the direction of the belt's progress by 1μ, and one of the springs is pulled in the temporary return direction of the scraper holder 1, and one of the springs is loosened. , which secrets are automatically held. Protects the conveyor belt and ensures safety when cleaning. Installation v
The obscurity of the l method is noticeable. It has the following features.

Claims (1)

[Scope of Claims] A plurality of rows of scrapers 1 that make up the abrasion-resistant hard scraper 2 are connected individually so that they can be tilted back and forth, and the shafts are attached to the support plate 5 so as to act in the tilt direction caused by the running of the belt 22. The scraper itself is supported by the support plate 5 of A for insertion and removal and rotation. The head 12 and spring 19 of the kite head B are supported by the spring 19 in the kite groove 18 of the support stand C so that the jJoid head B, which is neglected to be fixed, can be moved up and down.
Attach the cylinder of the scraper 2 and the spring 19 with the bolt 20.
