Description
Technical field
The present invention relates to a kind of rubbish storage and transportation apparatus, particularly the device for opening and closing back door of rubbish of rubbish container.
Background technology
In the prior art, a kind of garbage compression box back door is arranged, its patent No. is: ZL200520072708.4, this device mainly includes the compartment, and the rear portion, compartment is provided with the back doorframe, cooperates on the back doorframe back door is installed, establish ratchet device and the pull bar that has handle in the side in compartment, establish shift fork and jam plate in doorframe side, back, on the back door, establish the lock pin that is complementary with jam plate and shift fork, be provided with packing seal on the carriage back door frame and between the fitting surface at back door; Be connected rotationally through being connected bearing pin between top, back door and the compartment, top, back door backward, the downward-sloping straight trough that is provided with, described connection bearing pin inserts in the described straight trough.During work, handle by the rotating drive ratchet device, the rotation of ratchet device drives the rotation of pull bar, pull bar will rotatablely move and change straight-line motion into, promote shift fork, shift fork rotates around a fixed pin shaft, and its opening part promotes lock pin and moves up, drive the back door and move up and inside compression seal pad along jam plate, reach locking back door and leak free purpose with the lock pin of establishing thereon.The weak point of this device is: its control is convenient inadequately, and in the switching process of back door, lock pin collides shift fork easily, and its antagonistic force breaks ratchet device easily, has influenced the reliability of service of device.
Summary of the invention
The purpose of this invention is to provide a kind of device for opening and closing back door of rubbish bin, make the opening and closing at back door convenient, reliability of service is better.
The object of the present invention is achieved like this: device for opening and closing back door of rubbish bin, comprise the compartment, the rear end, compartment is provided with the back doorframe, cooperate the back door is installed with the back doorframe, fitting surface with the back door on the doorframe of described back is provided with packing seal, be connected rotationally through being connected bearing pin between top, back door and the compartment, both sides, top, back door backward, the downward-sloping straight trough that is provided with, described connection bearing pin inserts in the described straight trough, both sides, described compartment are hinged with the bidirectional hydraulic oil cylinder respectively, the long-armed end of the piston rod external part of bidirectional hydraulic oil cylinder and a L-shaped locking arm is hinged, the galianconism of locking arm inserts closing the door between spacing bearing pin and the door open limit bearing pin of being provided with on the back door, and the middle part of locking arm is hinged with the back doorframe.
When the present invention works, the bidirectional hydraulic oil cylinder can promote locking arm and rotate around its hinge-point with the back doorframe, when the galianconism of locking arm moves downward, it can promote the door open limit bearing pin and move downward, the radius of turn that breaks away from galianconism until the door open limit bearing pin, the door open limit bearing pin can drive the back door and move downward, top, back door is downward by straight trough, motion backward, make the back door break away from the back doorframe, subsequently, the back door can be rotated around connecting bearing pin, when the compartment front end upwards rotates, the back door by gravity is thoroughly opened, and the compressed garbage in the compartment can be toppled over out from the back door; When the compartment resets, the back door is closed, bidirectional hydraulic oil cylinder counteragent, the galianconism of locking arm enter once more closes the door between spacing bearing pin and the door open limit bearing pin, and piston rod continues motion, the galianconism contact of locking arm is at the spacing bearing pin of closing the door, and the locating dowel pin that promotes to close the door axially goes up motion, back door integral body forward, upward movement, the back door is pressed on the packing seal on the doorframe of back, make the rear portion, compartment realize sealing, the exudation of rubbish can not flow out and contaminated environment.Compared with prior art, the present invention opens and closes flexibly, the back door locking or the remote-controlled control that gets loose, and the bidirectional hydraulic oil cylinder is shock-resistant, and its use is more reliable, the back door good leak tightness, no leak in transit, the present invention can be used for treatment of urban garbage.
For can guarantee can be well airtight between back door and the back doorframe, back doorframe both sides also are provided with the locating plate that stretches out backward, the locating plate rear end becomes hook-shaped extension backward, downwards, the corresponding spacing bearing pin of locking that is provided with in both sides, back door with locating plate, when the back door is closed, lock spacing bearing pin and snap in the hook-shaped extending part downside of locating plate, simultaneously, connect the lower end that the bearing pin correspondence is positioned at straight trough.Locating plate and lock spacing bearing pin can will the back door and the back doorframe between further locking, reduce the possibility that the distortion of sealing position is leaked.
For guaranteeing that motion is flexible, avoid impact damage, described locking arm is arcwall face with the contact surface of close the door spacing bearing pin and door open limit bearing pin.
