Disclosed is a jaw crusher with double crank-rocker mechanisms, which comprises a housing (1), a fixed jaw plate (6), a movable jaw plate (5), a crank-rocker mechanism and a driving wheel. The crank-rocker mechanism has a front crank-rocker mechanism comprising an eccentric drive shaft in the form of crank, a front movable jaw (4) in the form of link and a front toggle plate (7) in the form of rocker and a rear crank-rocker mechanism comprising an eccentric drive shaft in the form of crank, a rear movable jaw (8) in the form of link and a rear toggle plate (9) in the form of rocker. The front and the rear crank-rocker mechanisms are either arranged on the same eccentric drive shaft (3) to form a jaw crusher with a single-eccentric drive shaft or respectively connected to a front and a rear eccentric drive shafts (15, 14) which are driven synchronously by transmission gears to form a jaw crusher with double-eccentric drive shafts. By the combination of the front and the rear crank-rocker mechanisms, the mechanical and structural properties of the lower portion of the movable jaw can be changed and the functionality of the jaw crusher can be improved greatly. |
