Unloading sand door rotating shaft has only an end that crank is arranged, stress all concentrates on a side, it is unbalanced unloading the stressed moment that produces of sand door, the pulling force that piston rod produced is also than normally satisfying the whole seal request that unloads the sand door greatly, impact when the material in the puddle mixer weighs and stirs, unload the deadweight of sand door, its integrated load is all born by the pulling force of piston rod.Also can cause when piston rod can not bear huge pulling force and unload the sand door and open Lou material.
Summary of the invention
The purpose of this utility model is that a kind of puddle mixer with auto-lock function of design unloads the sand door.This unloads the sand door by behind the oil cylinder piston rod seal puddle mixer discharge port.Unloading the sand door can close and put in place and keep sealing not leak material.In puddle mixer running, unload sand Men Buhui opening, do not have raw material and bleed in the molding sand bucket.Because of the piston rod of oil cylinder does not bear pressure, thereby yet can not unload the sand door and open Lou material because of oil cylinder, piston rod go wrong to cause.
The technical solution of the utility model is: a kind of puddle mixer with auto-lock function unloads the sand door.The puddle mixer chassis is contained on the frame.Have discharge port in the middle of the bottom, puddle mixer chassis.Unload the sand door unload that sand Fomento plate the right links mutually by turning joint and frame and can be around the rotation hinge through.The sand door sealing that unloads that can cover the puddle mixer discharge port is housed on unload sand Fomento plate to be covered.Be equipped with in the middle of unloading below the sand Fomento plate and unload sand door hinged seat, short connecting rod by bearing pin I with unload sand door hinged seat and be connected.In frame lower the frame hinged seat is housed.Long connecting rod is connected with the frame hinged seat by bearing pin II.The oil cylinder that is connected with Hydraulic Station is fixed on the frame.One hinges links together oil cylinder piston bar, short connecting rod and long connecting rod moveable hinge by bearing pin III.
The utility model course of work and principle are:
When oil cylinder makes in the piston rod retraction oil cylinder under Hydraulic Station drives, this moment, the oil cylinder piston bar was moved to the left by moving long and short connecting rod one end of hinges rubbish, and the long connecting rod other end rotates around the frame hinged seat.Short connecting rod is moved to the left under oil cylinder piston bar pulling, and the below is mobile left around swing hinge by unloading sand Fomento plate and unloading the sand door that unloads that sand door sealing lid forms by unloading the pulling of sand door hinged seat for the short connecting rod other end.When in the complete retraction oil cylinder of oil cylinder piston bar, unload the sand door as shown in Figure 2 and be in open mode.
When oil cylinder made piston rod stretch out oil cylinder under Hydraulic Station drives, the oil cylinder piston bar promoted long and short connecting rod one end by hinges and moved right this moment, and the long connecting rod other end rotates around the frame hinged seat.Short connecting rod moves right under the oil cylinder piston bar promotes, and the short connecting rod other end promotes by unloading sand Fomento plate and unloading the sand door that unloads that sand door sealing lid forms and move to the upper right side around swing hinge by unloading sand door hinged seat.When the oil cylinder piston bar stretches out oil cylinder fully, unload the sand door as shown in Figure 1 and be close on the puddle mixer discharge port and and seal up fully discharge port.
When the oil cylinder piston bar stretched out oil cylinder fully, long and short connecting rod just in time was in same linear position, and the synthetic load that unloads the sand door this moment is fully by long and short connecting rod and unload sand door hinged seat, hinges, frame hinged seat and put forth effort on frame.As long as oil cylinder is failure to actuate, double link just is in supporting always and unloads the sand door and make and unload the sand door and be in the state of automatically locking always.This structure makes unloads sand Men Buhui and problem not in place and that leak material occurs closing.Unloading the sand door in puddle mixer running also can opening, does not have raw material and bleeds in the molding sand bucket.Because the piston rod of oil cylinder does not bear pressure, thereby yet can not unload the sand door and open with Louing and expect because of oil cylinder and piston rod thereof go wrong to cause.
