In order to timely monitor broken chain,chain loss and other failure problems in the production of scraper conveyor in the soybean pretreatment workshop,to ensure the equipment safety of the scraper conveyor,the causes of the failure of the scraper conveyor broken chain and chain loss were analyzed,and the application of scraper broken chain protector to the scraper conveyor was put forward.Scraper broken chain protector consists of speed sensor and signal processor.When the scraper conveyor appears broken chain or chain loss failure,the frequency of the plulses transmitted by the speed sensor decreases,and the signal processor can quickly and effectively respond to the rapid shutdown and sound and light alarm by detecting the pluse frequency to protect the equipment and production safety.Broken chain protector is simple in structure,easy to install,and does not affect the normal operation of the scraper conveyor,suitable for application in some traditional enterprises.
