On the one hand the utility model provides a kind of dustbin, the dustbin includes garbage box 1, back door 2 and driving machine
Structure 3, the rear end of the garbage box 1 have opening, and the front end that the opening is increasingly towards the garbage box 1 from bottom to up is inclined
Tiltedly, the back door 2 includes outstanding arc-shaped end plate 21 and can seal to cover the opening, and the driving mechanism 3 is used for
The back door 2 is driven in the sealing open closed position and described in the complete opening positioned at the top of garbage box 1
Rotationally moved between open open position, in rotation process, the inner side at the back door 2 is all the time towards the garbage box
1。
In the above-mentioned technical solutions, as shown in Figure 1, the rear end opening of garbage box 1 is increasingly towards rubbish from bottom to up
The front end of babinet 1 tilts, and produces interference when avoiding opening and closing back door 2 with garbage box 1, and back door 2 includes outstanding
Arc-shaped end plate 21, is conducive to increase the volume of dustbin, reduces cost of transportation to a certain extent, while coordinate driving mechanism
3 can make back door 2 in the sealing open closed position and in the opening of opening completely positioned at the top of garbage box 1
Open position between rotationally move, in rotation process, the inner side at the back door 2 all the time towards the garbage box 1, from
And make back door moving range is smaller between a closed position and a open position, specifically, as shown in Figure 1, driving mechanism 3 can be set
Being set to makes back door 2 be moved all the time in cambered surface X when being opened and closed, and avoids and the service of connection devices (such as rear-loading type rubbish
Compression vehicle turns over barrel) interference is produced, part is hardly damaged, facilitates docking, while also reduces rubbish situation of being scattered
Occur, be conducive to the raising of operating rate.
Wherein, in order to make back door 2 to be moved under the driving of driving mechanism 3 in smaller range, it is preferable that after described

The free bearing of one connecting rod 31 is spacing to be supported the first position of the second connecting rod 32 with fixation and is fixed on the another of the U-shaped board body 5
Rotated between the second place of one end.That is horizontal supporting plate A is also used to the other end offer support of supporting rod 4, together
The free bearing of Shi Peihe first connecting rods 31, you can the position of the other end of fixed supporting rod 4, so that second connecting rod 32 and back door 2
Position fix.
As shown in figure 4, when back door 2 is in the closed position, the extending direction of first connecting rod 31 can be with horizontal supporting plate A's
Extending direction is parallel, so on the one hand makes the structure of dustbin neat, on the other hand, in pressurizing unit (such as shoveling) by rubbish
When being extruded to the arc-shaped end plate 21 at back door 2, i.e., when exerting a force towards arc-shaped end plate 21, first connecting rod 31 can provide opposite direction
Power, so makes structure stress more reasonable, equipment safety performance is higher.
In addition, as shown in figure 4, U-shaped board body 5 is set to be also convenient for when without using supporting rod 4 (back door 2 is in the closed position)
The other end of supporting rod 4 is packed up.Also, the other end of supporting rod 4 can be fixed on the another of U-shaped board body 5 in several ways
End, such as one of other end of the other end of supporting rod 4 and U-shaped board body 5 above set groove, set and can turn in another one
Turn the plate in the insertion groove, but in order to simplify structure and reduce the weight of device, it is preferable that the supporting rod 4
The other end of the other end and the U-shaped board body 5 is respectively arranged with corresponding first through hole and the second through hole, and axis pin is through described the
One through hole and second through hole are set so that the other end of the supporting rod 4 can be fixed on the other end of the U-shaped board body 5
On.
Since for loading rubbish as much as possible, the rubbish in garbage box 1 generally have passed through extruding, so will after
When door 2 is opened, the rubbish in garbage box 1 can be spread to open side and above from opening, and the rubbish forwardly spread can
Into in the service of connection devices (such as back-loading type waste compacting vehicle) docked with garbage box 1, and then hold from the rubbish of side diffusion
Easily drop on the ground, cause environmental pollution and need to spend the time to be cleared up, it is preferred that the dustbin includes
Be arranged on the open both sides for the side shield 6 that prevents rubbish from dropping from the side of the garbage box 1.Also, such as Fig. 3
Shown, the shape of side shield 6 can be roughly the same with the shape of the side plate 23 at back door 2, is so in as shown in Figure 4 at back door 2
During closed position, the structure of dustbin is more neat, can lift user experience.
The utility model second aspect provides a kind of garbage truck, and the garbage truck includes above-mentioned dustbin.Due to above-mentioned
Garbage truck includes above-mentioned dustbin, therefore has the advantages that all of the dustbin.
