Automatic adjusting device of scraper conveyor chain tension

Automatic adjusting device of scraper conveyor chain tension, including adjustment hydraulic pressure jar, hydraulic pressure stabilizing mean, the shutting button is shut down to feed liquor pipe connector mouth and time liquid pipe connector mouth, adjustment hydraulic pressure jar includes right cavity, telescopic link and left cavity, and the telescopic link is connected with the scraper conveyor sprocket, through moving, realizes scraper conveyor chain tensioning or lax about the flexible control scraper conveyor sprocket of telescopic link, and then realizes the tensile adjustment of chain, hydraulic pressure stabilizing mean respectively with the right cavity of adjustment hydraulic pressure jar, feed liquor pipe connector mouth with liquid pipe interface connection returns, through feed liquor pipe connector mouth or return liquid pipe connector orad right side cavity pours into into or the drain to hydraulic pressure keeps setting for the within range in making right cavity, and then control stretching out and drawing back of telescopic link. The utility model discloses can ensure that scraper conveyor chain moves with best tension all the time, the effectual life who improves scraper conveyor chain reduces maintenance frequency, reduces and maintains intensity to effective improvement is combined and is adopted working face production efficiency.
