The specific embodiment
Below in conjunction with specific embodiment, the present invention will be further described.
As depicted in figs. 1 and 2, the center discharging structure of puddle mixer is rotated on a kind of chassis, comprise oil cylinder 3 and unload sand door body 6, the tail end of described oil cylinder 3 is supported on cylinder support 1 by attachment pegs 2, described cylinder support 1 is arranged on puddle mixer base, the piston rod of described oil cylinder 3 by piston rod contiguous block 17 with unload sand door body 6 and be connected, described piston rod contiguous block 17 contacts with contiguous block guide 18 with contiguous block straight pin 19, describedly unload sand door 6 and unload sand door rotating shaft 4 and be rotationally connected, the described sand door rotating shaft 4 that unloads is arranged on connection bearing 5, described unloading on sand door body 6 is provided with and unloads sand door card 10, the described sand door card 10 of unloading is the parts on puddle mixer chassis.
Operation principle is: oil cylinder 3 is as driving body, unload sand door body 6 as link motion body, unload in sand door body 6, upper and lower end is separately installed with bearing positioning sleeve 14, center chassis axle 15, the gland 9 between two-row ball bearing and self-aligning roller bearing and bearing and unloads sand door bottom sealing plate 16, oil cylinder 3 stretches out the rectilinear motion returning, and unloads sand door body 6 and does 90 ° rotatablely moving.Puddle mixer is when mulling duty, the piston rod of oil cylinder 3 stretches out, sand door body 6 is unloaded in driving and the sand door card 10 of unloading that connects is docked in the chassis of horizontal level and puddle mixer card, when puddle mixer work completes need to be by the good molding sand discharging of mixed grind time, the piston rod of oil cylinder 3 returns, driving unload sand door body 6 and connect unload sand door card 10, take and unload sand door rotating shaft 4 as pivot point center, do the rotation of 90 °, unload sand door card 6 and forward the vertical position of unloading sand work to by former horizontal mulling operating position, in the time of can guaranteeing that like this oil cylinder 3 stretches out, unload sand door card 10 is horizontal when mulling duty, when oil cylinder 3 returns, unload sand door card 10 when unloading sand duty in the upright position of 90 °, unloading sand door opens completely.
