The deficiency in face, can not shut down when disconnected scraper plate or side chain rupture, even if chain rupture all occurs for both sides, also will not hard stop, scrapper conveyor
Length is longer, and chain rupture position is more remote away from tail wheel, and protection reaction is more blunt.
The second way is that mechanical detection device is installed in scraper plate both sides, detection scraper plate operation, when one or both sides signal
Detection then, does not start stoppage protection action.It is machinery in actual applications, between mechanical device and scraper plate for which
Collision, the abrasion of device is very big, it is necessary to often change touch points, and this does not accomplish in the enterprise continuously run for a long time；Machine
Tool device is arranged on above scraper plate, and debris larger in (such as 300mm) scrapper conveyor can damage device when closer to the distance；Distance compared with
When remote, mechanical device cannot be guaranteed that every scraper plate all detects like clockwork, and reliability reduces.No matter which kind of mode, sending out
It can not all be shut down in time when raw disconnected scraper plate, chain rupture, cause the accident expansion, break down time length, and loss is huge.
