Description

Technical Field

[0001] The invention relates to the technical field of conveyors, and in particular to a coal mine scraper conveyor. Background Art

[0002] Scraper conveyor is a kind of conveying equipment commonly used in industrial fields such as coal mines and mines. Scraper conveyor is suitable for conveying various materials such as powder, block, granular, etc. Scraper conveyor is suitable for horizontal or inclined transportation, and can effectively transport coal and other materials from one place to another.

[0003] A mining assembled scraper conveyor disclosed in Chinese patent CN118495042A includes two outer shell plates and two rollers, and also includes two symmetrical chain assemblies and a quick-release mechanism arranged between the two outer shell plates. The two rollers are rotatably connected between the two outer shell plates. A group of sprockets are arranged on the outside of the two rollers, and each group of sprockets is fixed at both ends of the rollers. The two groups of sprockets are respectively connected by two chain assemblies.

[0004] However, compared with the prior art and the comparative scheme, it can be seen that the scraper conveyor still has the following problems in actual use: When conveying the raw coal mined underground, the coal blocks mined are of different sizes and the distribution of the coal blocks on the scraper conveyor is also random. At the same time, after the coal blocks fall on the scraper conveyor, they may roll left and right on the scraper conveyor after being hit by other coal blocks during the conveying process. Therefore, when the chain drives the scraper to convey the coal blocks, the number of coal blocks distributed on the left and right sides of the scraper is different, which makes the loads on the left and right sides of the scraper different during the movement. The different loads on both sides will cause the scraper as a whole to tilt toward the side with greater load. Once the scraper tilts, the coal blocks will further tilt toward the scraper under the guidance of the scraper The coal is gathered on one side, thereby increasing the load on the inclined side of the scraper, which in turn causes different forces on the chains on both sides of the scraper. When the difference in the number of coal blocks distributed on both sides of the scraper is large, which makes the load difference on both sides of the scraper large, it will affect the synchronization of the chains on both sides of the scraper. Once the synchronization of the chains on both sides of the scraper deviates, it may cause the meshing of the chain to be misaligned and then cause the chain to break, affecting the normal operation of the scraper conveyor. Moreover, the function of the scraper conveyor is not only to transport coal and materials, but also to serve as the running track of the coal mining machine. Once the scraper conveyor cannot operate normally, the entire coal mining face will be shut down, causing the entire production to be interrupted. Summary of the invention
