Description

Technical Field

[0001] This application relates to the technical field of scraper conveyor chutes, and specifically to a wear-resistant lightweight scraper conveyor chute. Background Art

[0002] In the fields of coal, mining, and material transportation, the scraper conveyor is a key equipment, and its performance and stability are directly related to production efficiency and cost. The chute in the scraper conveyor, as the material transmission channel, endures the friction and impact of materials for a long time. Therefore, its wear resistance and corrosion resistance have become important indicators for measuring the performance of the chute. Traditional chutes are mostly welded from ordinary steel. Although they have a certain load-bearing capacity, their wear resistance is often difficult to meet the requirements under harsh working conditions. After long-term operation, the surface of the chute is prone to wear and corrosion, resulting in material leakage and a decrease in transportation efficiency.

[0003] At present, when the scraper conveyor chute is working, it will be subjected to a large amount of friction and impact generated during the rolling of materials, which will greatly reduce the service life of the chute. And the chute is usually welded, which is not convenient for individual maintenance and replacement of a certain chute, and requires the scraper conveyor to be shut down for a long time, affecting the working efficiency of the scraper conveyor.

[0043] In a wear-resistant light scraper conveyor chute in this embodiment, the material in the chute can be separated by the spacer plate 8 arranged on the top of the wear-resistant steel plate 7, reducing the space for the material to roll in the chute. Through the cooperation of the fixing plate 2 and the connecting plate 3, the channel plate 4 can be disassembled from the chute for separate maintenance and replacement, achieving a significant reduction in the rolling of the material in the chute, reducing the friction and impact generated by the material on the chute, improving the service life of the chute. The whole chute is arranged in a splicing manner, and it is convenient to

[0044] The working principle of the above embodiment is as follows: When the material enters the chute and lands on the top of the wear-resistant steel plate 7, the spacer plate 8 will separate the material on the top of the wear-resistant steel plate 7, so that when the scraper 9 scrapes in the chute, the material can only move between two adjacent spacer plates 8, reducing the amplitude of the material moving with the scraper 9 on the top of the wear-resistant steel plate 7.

When it is necessary to replace the wear-resistant steel plate 7, rotate the threaded rod 17 to gradually move the corresponding two push plates 18 closer. The push plate 18 will drive the positioning block 19 to move out of the inner wall at one end of the positioning frame 6, so that the positioning block 19 releases the restriction on the positioning frame 6. Pull the wear-resistant steel plate 7 upward to move the positioning frame 6 out of the positioning hole 5, separate the wear-resistant steel plate 7 from the chute plate 4, replace the new wear-resistant steel plate 7, insert the corresponding positioning frame 6 into the positioning hole 5, rotate the threaded rod 17, drive the corresponding two push plates 18 to gradually move away, so that the push plate 18 drives the positioning block 19 to insert into the inner wall at one end of the positioning frame 6. The inclined outer surface at one end of the positioning block 19 will gradually push the positioning frame 6 downward, so that the positioning frame 6 drives the wear-resistant steel plate 7 to closely adhere to the top of the chute plate 4 until the positioning block 19 is completely inserted into the inner wall at one end of the positioning frame 6. Then, reinstall the chute plate 4 between the two chute sides 1 and use bolts to connect the fixing plate 2 and the connecting plate 3.
