Description

Technical Field

[0001] This utility model relates to the field of scraper conveyor material adjustment technology, specifically a scraper conveyor uniform material adjustment device. Background Technology

[0002] A scraper conveyor is a transport device that uses a scraper chain to continuously move within a trough to transport bulk materials. It is widely used in mining, metallurgy, building materials, power, and chemical industries, and is particularly suitable for horizontal or inclined conveying of granular, powdery, and small lump materials. With its simple structure, strong conveying capacity, and wide adaptability, it is one of the key pieces of equipment for material transfer in industrial production.

[0003] Existing scraper conveyors have the following shortcomings in practical applications: First, poor material uniformity. Traditional equipment lacks an effective material adjustment mechanism, making it easy for materials to accumulate or be unevenly distributed during conveying, affecting subsequent processing accuracy and conveying efficiency. Second, insufficient adjustment flexibility. Most equipment has fixed parameters such as scraper spacing and conveying angle, making it impossible to quickly adjust according to material characteristics (such as particle size and density). Third, inconvenient inspection and maintenance. The internal structure of the equipment is enclosed, and troubleshooting requires disassembling a large number of parts, which is time-consuming and labor-intensive. Fourth, limited mobility and adaptability. The fixed installation design cannot meet the needs of multi-scenario operations, and some vulnerable parts have insufficient wear resistance, resulting in a shortened service life of the equipment.

[0009] As a further improvement of this utility model: the quick-release observation and maintenance port is made of transparent acrylic sheet material, with sealing strips on the edges, and the handle is a folding structure.

[0010] As a further improvement of this utility model: the bearing is a deep groove ball bearing, which is interference-fitted with the rotating shaft, and the outer ring of the bearing is fixed to the inner wall of the housing by a snap ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting symmetrically distributed adjustment plates and waist-shaped adjustment holes, this utility model can flexibly adjust the width and uniformity of the fabric according to the particle size of the material and the conveying requirements, thus solving the problem of uneven fabric distribution in traditional equipment.
