Belt conveyor

Abstract

The invention discloses a belt conveyor which comprises a head, a middle section and a tail. The belt conveyor is characterized by further comprising a sweeper and a deviation rectification device; the sweeper comprises two oscillating rods, a fixed shaft, a fixed bearing, a steel pipe, a sweeping plate and a scraper plate; the deviation rectification device comprises an H-shaped carriage, an upper bearing track, a lower bearing track and four adjusting devices; the four ends of the H-shaped carriage are each provided with a sliding roller, and the four sliding rollers are located on the corresponding upper and lower bearing tracks respectively; the four adjusting devices are located at the four ends of the H-shaped carriage respectively; and each adjusting device comprises an adjusting support, an adjusting screw rod, a horizontal pulley and a horizontal sliding way, wherein one end of the adjusting screw rod is connected with the lower end of the adjusting support, the other end of the adjusting screw rod is connected with the horizontal pulley, and the horizontal pulley is located on the horizontal sliding way. The sweeper bears tensioning force applied by a spring while scraping away materials, so that the phenomenon that the scraper plate of the sweeper displaces due to material resistance is avoided, and materials can be stably and efficiently scraped away in the material conveying process all the time; and the tensioning roller deviation angle can be adjusted, the belt friction resistance is reduced, and the defect that the screw rods are not supported stably due to deflection of the carriage is overcome.

Description

technical field [0001] The invention relates to a belt conveyor, in particular to a belt conveyor with self-cleaning and anti-deflection functions. Background technique [0002] The material conveyed by the belt conveyor is bulk material, and the discharge port is set at the head. When the head discharges, there will be a certain amount of bulk material remaining on the conveyor belt. When the conveyor belt leaves the discharge port, the sticky material must be removed. The material attached to the conveyor belt is scraped off. The setting of the cleaning device of the existing belt conveyor is generally to set a scraper above the conveyor belt. With the operation of the conveyor belt, the scraper scrapes off the material, but as the material continues to increase, the scraper scrapes the material. The resistance is also increasing, and the scraper may be displaced by force, so that the gap between the scraper and the conveyor belt becomes larger, resulting in unclean scrap...

AI Technical Summary

Problems solved by technology

The setting of the cleaning device of the existing belt conveyor is generally to set a scraper above the conveyor belt. With the operation of the conveyor belt, the scraper scrapes off the material, but as the material continues to increase, the scraper scrapes the material. The resistance is also increasing, and the scraper may be displaced by force, so that the gap between the scraper and the conveyor belt becomes larger, resulting in unclean scraping of the material

[0003] The belt often deviates during the operation of the belt conveyor. There are many reasons for the deviation. The common reasons for the deviation of the belt are as follows: one is that the original size of the belt is not well controlled when it is glued, so that the closed The tape produces a bell mouth shape, which will inevitably cause deviation during the operation of the belt

The second is that the feeding point on the belt is not on the center line of the belt running, and the impact of the material makes the belt slip to one side, causing the belt to deviate

The third is that the material is not uniform, the size of the material blocks varies greatly, and the belt is partially loaded unevenly, which makes the belt deviate.

The fourth is the deflection of the installation of the bearing roller group, and the original accumulation will also cause the belt to deviate to a certain extent.

The fifth is that the tension on both sides of the tensioning roller is inconsistent, and the tension of the belt is not balanced, causing the belt to deviate
