Description

Technical Field

[0002] The middle trough of the scraper conveyor is the body of the scraper conveyor, which is composed of the middle plate and trough side steel. The upper trough is used to transport coal and the lower trough is used for the return of the scraper chain. The middle trough of the scraper conveyor is mainly used for scraper conveyors and transfer machines underground in coal mines. Among the existing coal mining machinery, the scraper conveyor is a more commonly used machine.

[0003] The middle trough of the scraper conveyor is a wearing part and requires frequent maintenance. The existing scraper trough is usually fixed by pads and pressure plates during maintenance. The problem is that the fixing operation of this fixing method is cumbersome and difficult to operate. At the same time, when the middle trough of the scraper conveyor is damaged on multiple sides, it needs to be turned over and clamped and positioned again for further maintenance. Since the middle trough of the scraper conveyor is large in size, it is inconvenient to turn it over, which reduces the maintenance efficiency. Therefore, we propose a scraper conveyor middle trough maintenance and positioning tool to solve this problem. Utility Model Content
