Embodiment
Understand that sprocket wheel protective cover plate 5 and pawl 10 are coupled by pin II 13 by Fig. 1~2, hydraulic cylinder 7 and gusset piece 14
Coupled by pin I6, hydraulic cylinder 7 and pawl 10 are coupled by bearing pin I11, sprocket wheel protective cover plate 5 and gusset piece 14 pass through pin
III 16 couples, and such hydraulic cylinder 7, pawl 10, gusset piece 10, sprocket wheel protective cover plate 5 constitute crank and rocker mechanism.Wherein
Sprocket wheel protective cover plate 5 is frame, and 6 cranks of hydraulic cylinder, pawl 9, gusset piece 10 are rocking bar.
Understand that pawl 10 is welded by left claw 101, gusset piece 102, right pawl 103 by Fig. 3~4, its centre-to-centre spacing and chain
Take turns chain pitch consistent.Left claw 101, the upper end of right pawl 103 are half concave arc, its arc radius R1 >=scraper plate vertical chain ring exradius chi
Very little R2；Hydraulic cylinder piston rod is connected by bearing pin I11 and pawl 10, spacing with split pin 16.Divide in left claw 101, right pawl 103
