Four-connecting-rod mechanism taking connecting rod as driving component and used on scraper blade material taking device

The invention relates to a four-connecting-rod mechanism taking a connecting rod as a driving part and used on a scraper reclaiming device, in particular to a four-connecting-rod mechanism taking a connecting rod as a driving part and used on a scraper reclaiming device in a large portal type double-scraper reclaimer. The gate-type double-scraper material taking machine is mainly used for a large gate-type double-scraper material taking machine which has high requirements on material taking automation effect, equipment energy conservation and intelligence in a material yard. According to the invention, the problem of independent intelligent control of the auxiliary scraper reclaiming device is solved, the auxiliary scraper reclaiming device can be started according to the actual condition of a material pile, the energy consumption of the equipment is minimized, full automatic reclaiming can be realized during reclaiming, meanwhile, the phenomenon that the auxiliary scraper reclaiming device is easily stuck in
