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 dustbin.
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 mechanism 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 sealing mat on the carriage back door frame and between the fitting face 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, said connection bearing pin inserts in the said straight trough.During work, through the handle of rotating drive ratchet mechanism, the rotation of ratchet mechanism drives the rotation of pull bar; Pull bar will rotatablely move and change rectilinear 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 the purpose of locking back door and sealing with the lock pin of establishing above that.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 reaction force breaks ratchet mechanism easily, has influenced the dependability 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, dependability is better.
The objective of the invention is to realize 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, cooperates with the back doorframe back door is installed; Fitting face with the back door on the doorframe of said back is provided with sealing mat; 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, said connection bearing pin inserts in the said straight trough; Both sides, said 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, and 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 worked, the bidirectional hydraulic oil cylinder can promote locking arm and rotate around its pin joint with the back doorframe, when the galianconism of locking arm moves downward; It can promote the door open limit bearing pin and move downward, and until the radius of gyration of door open limit bearing pin disengaging galianconism, the door open limit bearing pin can drive the back door and move downward; Top, back door through straight trough downwards, 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 rotated, thoroughly opened under action of gravity at the back door, and the compressed garbage in the compartment can be toppled over out from the back door; When the compartment resetted, the back door was closed, bidirectional hydraulic oil cylinder counteragent; The galianconism of locking arm gets into once more closes the door between spacing bearing pin and the door open limit bearing pin, and piston rod continues motion, and the galianconism contact of locking arm is at the spacing bearing pin of closing the door; And the spacer pin that promotes to close the door axially goes up motion, back door integral body forward, move upward, the back door is pressed on the sealing mat on the doorframe of back; Make the rear portion, compartment realize sealing, the diffusate 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, and the back door good leak tightness does not have leakage in transit, and 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 location-plate that stretches out backward, and the location-plate rear end becomes hook-shaped extension backward, downwards, the corresponding spacing bearing pin of locking that is provided with location-plate in both sides, back door; When the back door is closed; Lock spacing bearing pin and snap in the hook-shaped extending part downside of location-plate, simultaneously, connect the lower end that the bearing pin correspondence is positioned at straight trough.Location-plate and lock spacing bearing pin and can further locking between back door and the back doorframe have been reduced the possibility that the distortion of sealing position is leaked.
For guaranteeing that motion is flexible, avoid impact damage, said locking arm is arcwall face with the contact surface of close the door spacing bearing pin and door open limit bearing pin.
