Background technology
S1823B type puddle mixer is that the moulding of single rotor inclination rotating chassis mixes control equipment with clay-bonded sand.It unloads the sand door and drives in the middle of the bottom.The switching of unloading the sand door is by HYDRAULIC CONTROL SYSTEM.Unload the sand door and divide rotatable and do not rotate two parts, its not a lateral edges of rotating part be fixed under the chassis on the methods, rack with hinge axis.Hydraulic system can drive unloads sand door rotating part and rotates nearly 90 °.One end of hinge axis is fixed with a crank with key, and the swing of crank is controlled by hydraulic jack, and the oil cylinder piston bar unloads the sand door and opens when stretching out, and unloads the sand door during withdrawal of oil cylinder piston bar and closes, and the hydraulic oil of oil cylinder is supplied with by Hydraulic Station.
Unload the sand door and close the back puddle mixer and start working, occur unloading the sand door at work habitually in the past and close not in place and leak material and occur unloading sand Men Kaiyi openning in turning round with puddle mixer suddenly and cause the raw material situation such as molding sand bucket of bleeding.The pulling force that keeps sealing in whole mulling process when the piston rod packing part of oil cylinder bears and unloads the sand door and close.Like seal fails, pressure oil will from high pressure chest to low-pressure cavity or from high pressure chest to the outside seepage of piston rod, cause high pressure chest pressure to descend.When high pressure chest pressure descends, unload the sand door and also can close not in place or unload and open automatically after the sand door is under pressure.If output pressure fluctuation takes place Hydraulic Station in the course of the work, the pulling force of oil cylinder piston bar also can change, and acts on the pressure that unloads on the sand door material also can take place to leak when big.
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, and the pulling force that piston rod produced is also than normally satisfying the whole seal request that unloads the sand door greatly, the impact the when 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 objective of the invention is to design a kind of puddle mixer and unload the sand door with auto-lock function.This unloads the sand door through 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.
Technical scheme of the present invention 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.The sand Fomento plate the right of unloading of unloading the sand door links the moving hinge through that also can rotate mutually through turning joint and frame.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 through the 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 through the 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 through the bearing pin III.
The course of work of the present invention and principle are:
Make in the piston rod retraction oil cylinder when oil cylinder drives down at Hydraulic Station, the oil cylinder piston bar moved long and short connecting rod one end through the hinges rubbish and was moved to the left this moment, and the long connecting rod other end rotates around the frame hinged seat.Short connecting rod is moved to the left down in oil cylinder piston bar pulling, and the short connecting rod other end is through unloading the pulling of sand door hinged seat by unloading sand Fomento plate and unloading the sand door sealing and cover the sand door of forming that unloads and move to the lower left around swing hinge.When in the complete retraction oil cylinder of oil cylinder piston bar, shown in accompanying drawing 2, unload the sand door and be in open mode.
When oil cylinder drives when making piston rod stretch out oil cylinder down at Hydraulic Station, the oil cylinder piston bar promotes long and short connecting rod one end through hinges and moves right at this moment, and the long connecting rod other end rotates around the frame hinged seat.Short connecting rod promotes to move right down at the oil cylinder piston bar, and the short connecting rod other end promotes by unloading sand Fomento plate and unloading the sand door sealing and cover the sand door of forming that unloads and move to the upper right side around swing hinge through unloading sand door hinged seat.When the oil cylinder piston bar stretches out oil cylinder fully, shown in accompanying drawing 1, unload the sand door 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 through 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.In puddle mixer running, unloading the sand door 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.
When needs unload sand, drive in the lower piston rod retraction oil cylinder at Hydraulic Station, unload the sand door and open this moment, and puddle mixer unloads sand.Unload and to start the oil cylinder piston bar after sand is accomplished and close and unload the sand door and carry out mulling next time again, unload the sand action.
Advantage of the present invention is to have designed a kind of puddle mixer with auto-lock function to unload the sand door.This unloads the sand door through behind the oil cylinder piston rod seal puddle mixer discharge port, unloads the sand door and can close and put, keep sealing in place and do not leak material.In puddle mixer running, unload sand Men Buhui opening, do not have raw material and bleed in the molding sand bucket.And, thereby yet can not unload the sand door and open with Louing and expect because of oil cylinder, piston rod go wrong to cause because the piston rod of oil cylinder does not bear pressure.
