Description
Technical Field
The invention relates to a garbage disposal device, in particular to a garbage can sealing door opening and closing device and a garbage can.
Background
The existing horizontal garbage compressor pushes garbage into the box body to be extruded after being butted with the matched split type garbage can, and when the garbage can is full of garbage, the compressor gate lifting mechanism pushes the box body material cutting door down to cut off the garbage. After the blank door closed rubbish, the phenomenon is smugglied secretly to the rubbish often can appear in the department that meets of blank door and back door opening, has the clearance between dustbin back door and the blank door, and is lower from ground height, and dustbin sewage overflows outside the box in clearance department easily. In order to shield and waterproof seal the joint of the rear door and the material cutting door, a sealing door is additionally arranged at the rear door. After the sealing door is closed, a gap exists between the sealing door and the rear door, and sewage in the box body easily leaks out of the box body through the gap. For satisfying the leakproofness requirement between sealing door and back door, prevent the sewage overflow, compress tightly, lock sealing door with the help of hydraulic power or manpower, current sealing door locking technique often adopts following two kinds of forms:
1) Oil cylinder driving locking structure
The structure is that a hydraulic oil cylinder and a connecting arm are arranged on the dustbin, one end of the connecting arm is hinged with the oil cylinder 12, the other end of the connecting arm is fixedly connected with a sealing door 4, and a sealing rubber strip 5 is arranged on the joint surface of the sealing door 4 and a dustbin body 1, as shown in figure 1. The connecting arm is provided with a hinge point, and the hinge point is provided with a pin shaft which can slide in a chute on the box body. The oil cylinder drives the connecting arm to enable the sealing door to translate and rotate, and the sealing door is opened and closed. After the sealing door is closed, the oil cylinder contracts to tightly press the sealing rubber strip at the sealing door, so that garbage scattering and sewage leakage are eliminated. Although the structure can realize pressing force on the sealing rubber strip, the hydraulic oil cylinder has the problem of internal leakage, so that the sealing door and the garbage can cannot be always kept in a tight sealing state, the pressing force is loosened due to vibration of the box body in the transportation process, the sealing performance of the sealing door cannot be completely guaranteed, and sewage leakage is caused.
2) Manual locking structure
The structure is that the left side of the airtight door is hinged on a rear door 2 of the dustbin, and the right vertical beam is provided with two shaft sleeves which are fixed up and down, as shown in figure 2. The handle is formed by bending a hollow pipe by 90 degrees, and the un-bent part of the hollow pipe can be used as a rotating shaft. The rotating shaft is arranged in a shaft sleeve on the right side of the airtight door 4, a lock hook is fixed on the upper part and the lower part of the rotating shaft, and the lock hook is matched with a lock plate 40 fixed on the rear door 2. The handle 30 can rotate freely in the horizontal plane around the axle center of the shaft sleeve, and a person can hold the tail end of the handle by hand and drag the handle to rotate. When the airtight door needs to be locked, the handle end can be held by a hand, the handle is rotated to be parallel to the rear door, the locking contact surface of the lock hook is rotated to be parallel to the rear door along with the handle and is contacted and attached tightly with the matching surface of the lock plate, then the handle is constrained and limited on the limiting seat fixed on the rear door by the bolt, and the handle is held by the hand when rotating around the shaft and the lever effect at the lock hook is utilized to compress the sealing rubber strip between the rear door and the airtight door to realize waterproof sealing. When the sealed door needs to be opened, the plug pin is only required to be pulled out, and the sealed door can be opened by loosening the handle. The structure is operated by a hand, the requirement on the precision of the installation and positioning size is high, the compression uniformity of the sealing rubber strip cannot be ensured by single-side locking, the size of the compression force cannot be adjusted, and the use and the maintenance are inconvenient.
More information about the above solution can also be found in the following documents:

The center of the top semicircle of the second chute 17 is coaxial with the axis of the third pin 18, at this time, the second pin 16 is coaxial with the third pin, and the connecting rod 15 and the swing arm 6 rotate synchronously. Because the position of the second pin shaft 16 is not changed any more, the combination rod 11 does not move, and the position of the hook plate 8 is not changed in the opening process of the sealing door 4.
As shown in fig. 7 to 9, which are schematic diagrams illustrating an opening process of the sealing door 4, when the sealing door 4 moves to fig. 7 and the connecting rod 15 is just in a horizontal state, the longitudinal direction of the first sliding chute 14 is inclined downward from front to back, and the first pin 13 is located at the front end of the first sliding chute 14 under the upward supporting force of the oil cylinder 12 and cannot slide in the first sliding chute 14.
When the sealing door 4 moves to the position shown in fig. 8, and the length direction of the first sliding groove 14 is just in the horizontal state, the connecting rod 15 is inclined upwards from front to back, and in the process that the sealing door 4 is continuously opened afterwards, the connecting rod 15 pulls the first pin 13, so that the first pin 13 is limited to slide upwards in the first sliding groove 14, and the first pin 13 is always located at the front end of the first sliding groove 14. The limiting function of the connecting rod 15 on the first pin 13 ensures that the opening process of the sealing door 4 is stable and smooth under the driving of the oil cylinder 12.
After the oil cylinder 12 is extended to the right position, as shown in fig. 9, the top surface of the swing arm 6 is just contacted with the top surface of the rubber bump 19, and the sealing door 4 is completely opened. The rubber striking block 19 is arranged on the supporting seat 20 and used for limiting and buffering the swing arm 6 and reducing the impact force of the swing arm 6, so that the sealing door 4 is kept stable under the interaction of the supporting force of the oil cylinder 12 and the counter force of the rubber striking block 19 after being opened.
On the contrary, the oil cylinder 12 can realize descending closing and locking of the sealing door 4 after being retracted, and the closing and locking process is opposite to the unlocking and opening process.
The embodiment also relates to a dustbin which comprises the dustbin sealing door opening and closing device.
To sum up, the single hydro-cylinder of dustbin bilateral symmetry arrangement can accomplish the coherent action that the drive sealing door opened and close and lock in a stroke within range, and it is firm to go up the hook plate locking, and locking elasticity degree is adjustable, has solved the problem of dustbin back door 2 and 4 clearance department sewage seepage of sealing door well, and this device simple structure, manufacturing cost is lower, convenient operation, the controllability is strong, is applicable to dustbin sealing door 4.
It should be noted that, although the above embodiments have been described herein, the scope of the present invention is not limited thereby. Therefore, based on the innovative concepts of the present invention, the technical solutions of the present invention can be directly or indirectly applied to other related technical fields by changing and modifying the embodiments described herein or by using the equivalent structures or equivalent processes of the content of the present specification and the attached drawings, and are included in the scope of the present invention.
