Description

Multi-stage elastic scraper device

technical field

The utility model relates to a scraper device, in particular to a multi-section elastic scraper device for scraping off the attachments on the surface of the conveyor belt.

Background technique

For example, the conveying equipment used to transport ore and other materials mainly uses the driven conveyor belt to transport the material from the source to the destination, and the automatic conveying equipment saves manpower. During the process of conveying ore and other materials on the conveyor belt of the aforementioned conveying equipment, some ore and other materials will adhere to the belt surface of the conveyor belt. The performance of the material, so the general conveying equipment will install at least one scraper device on the output side of the conveyor belt to scrape off the attachments on the surface of the conveyor belt.

Taking the first scraper device currently used to scrape off the surface attachments of the conveyor belt as an example, the composition of the known scraper device is mainly to install a scraper plate of a polymer material on a scraper shaft, wherein for the convenience of the scraper For the maintenance of the device, the scraper plate is selected as an integrally formed part, and then the two ends of the scraper shaft are respectively combined with an elastic adjuster to assemble on the output side of the conveyor belt, and the scraping edge at the end of the scraper plate is attached to the conveyor belt. The surface of the belt, and a predetermined elastic force is applied to the scraper plate through the scraper shaft through the elastic adjuster. When the conveyor belt transports ore and other materials, the attachment on the surface of the conveyor belt is scraped through the scraping end of the scraper plate. remove.

In the aforementioned scraper device, the combined structure between the scraper plate and the scraper shaft has the problem of inconvenient assembly and disassembly. Moreover, the scraper plate is an elastic member integrally formed of polymer materials. The type scraping part is pressed against the belt surface of the conveyor belt. Due to the friction of the conveyor belt after a long period of transportation of materials and the impact of the material falling on the conveyor belt, the belt surface of the conveyor belt will be damaged and appear uneven. Therefore, during the operation of the conveyor belt, the scraping end of the scraper plate touches the uneven part of the belt, which will cause the whole scraper plate to bounce. When the scraping end edge of the scraper board bounces back to the belt surface, there will be a buffer period during which the scraper board and the belt cannot press against the belt surface, causing the scraper device to be unable to scrape off the attachments on the belt surface.

Utility model content

The main purpose of this utility model is to provide a multi-section elastic scraper device. It is hoped that the utility model can solve the inconvenience of disassembling the existing scraper device, and the integrated scraper plate can scrape off the belt surface where the end edge abuts the conveyor belt. Problems such as poor scraping due to the overall bouncing effect.

In order to achieve the above purpose, the multi-stage elastic scraper device proposed by the utility model includes:

A multi-segment elastic scraper, which includes a metal fixing seat and an elastic scraper body, the bottom of the fixing seat forms a fixed slot that runs through the axial direction and opens downward, and the scraper body includes a base and a self-base The scraping part extending laterally and covering the fixed seat with the base part, the scraping part forms a plurality of slits extending from the outer edge of the scraping part toward the base at intervals, and divides the scraping part into multiple sections The scraping unit is integrally formed on the base and has independent elasticity. The scraping part forms a through hole at the end of each slit adjacent to the base, and the multi-segment elastic scraper is between the base of the scraper body and the fixed seat covered inside. The two axial ends respectively form assembly grooves extending axially inward from the outer end thereof and communicating with the fixing groove;

A scraper shaft, which includes a shaft and a fixed plate that is fixed on the shaft and extends axially. The two axial ends of the fixed plate are provided with fixed perforations, so that the multi-section elastic scraper can be rotated by the fixed groove at the bottom of the fixing seat. The sliding sleeve is connected to the fixing plate of the scraper shaft, and the fitting groove corresponds to the fitting hole of the fixing plate; and

A plurality of sets of fixing screws are respectively assembled at the assembling groove of the multi-section elastic scraper and the assembly hole of the scraper shaft, and fix the multi-section elastic scraper on the scraper shaft.

The multi-segment elastic scraper device of the utility model mainly uses the scraping part of the scraper body of the multi-segment elastic scraper to be divided into several scraping units with independent resilience. By applying the multi-segment elastic scraper device to the conveyor belt equipment, Use multiple scraping units of multi-segment elastic scrapers to contact the conveyor belt to scrape off the belt surface attachments. When a certain section of the belt of the conveyor belt is damaged, the multi-segment elastic scrapers only contact the scraping of the damaged section of the belt. The unit produces a bouncing effect, and the other scraping units still maintain a state of being closely attached to the belt surface, and are not affected by the damaged section of the belt to bounce together, ensuring a good scraping effect of the multi-segment elastic scraper device on the belt surface.

Furthermore, when the multi-segment elastic scraper group is set on the scraper shaft, the fixing screw of a set screw group can be pre-installed on one end of the fixed plate of the scraper shaft, and then the bottom of the fixed seat covered by the scraper body base of the multi-segment elastic scraper The fixing groove is aligned with the fixing plate of the scraper shaft, and the multi-segment elastic scraper slides axially along the fixing plate from the other end of the scraper shaft until the assembly groove at one end of the multi-segment elastic scraper touches the pre-assembled on the fixing plate of the scraper shaft. At the fixing screw, the multi-segment elastic scraper can be quickly aligned on the fixed plate of the scraper shaft, and then locked with the fixing screw group, which can achieve the effect of quickly setting the multi-segment elastic scraper on the scraper shaft. Improve the ease of disassembly and assembly of multi-segment elastic scrapers.
