The invention provides a garbage truck, which comprises a subframe 1, a garbage can 2 and a lifting device 3 for connecting the subframe 1 and the garbage can 2, wherein the lifting device 3 is arranged so that the garbage can 2 can translate between a first position for supporting the garbage can 2 by the subframe 1 and a second position for supporting the garbage can 2 by the lifting device 3 along the vertical direction and can keep the garbage can 2 at the first position, the second position and the positions between the first position and the second position.

In the above technical solution, since the lifting device 3 enables the dustbin 2 to translate between the first position (as shown in fig. 2) where the dustbin 2 is supported by the subframe 1 and the second position (as shown in fig. 1) where the dustbin 2 is supported by the lifting device 3 in the vertical direction and enables the dustbin 2 to be kept at the first position, the second position and the positions between the first position and the second position, the garbage truck can be in seamless docking with docking devices (for example, a garbage compression truck and a garbage transfer station) of different heights, material leakage is avoided, and since the garbage can move from the garbage truck into the docking device in the horizontal direction, no or small blanking height difference exists, dust is small, and meanwhile, since the garbage truck translates in the vertical direction, the moving distance is small, the operation is convenient and the time is saved.

As shown in fig. 1,2 and 3, in order to prevent other vehicles from penetrating into or colliding with the garbage truck, the garbage truck includes a guard H installed at the rear end of the sub-frame 1, the guard H includes a rear rail H1, and the length of the rear rail H1 extending out of the sub-frame 1 in the front-rear direction of the garbage can 2 is adjustable, so that the rear rail H1 can be in an initial state extending out of the sub-frame 1 by a certain length, i.e., a normal guard state, in a normal state where docking with other devices is not required. When the garbage truck is required to be in a working state of docking with a garbage transfer station or a rear-mounted garbage truck, in order to reduce the distance between the rear door 21 of the garbage truck and the feed port of the garbage transfer station or the rear-mounted garbage truck, the rear guardrail H1 may be in a contracted state of fully retracting or reducing the length of the extension sub-frame 1 so as to facilitate docking, in particular, as shown in fig. 3, the protection device H may further include a tension spring H2, a stopper H3 and a rotation shaft H4 provided on the sub-frame 1, and a rotation bracket H5 mounted on the rotation shaft H4, one end of the tension spring H2 is fixed on the sub-frame 1, the other end of the tension spring H2 is connected with one end of the rotation bracket H5, the rear guardrail H1 is mounted on the other end of the rotation bracket H5, the stopper H3 may restrict one-side rotation of the rotation bracket H5 around the rotation shaft H4, i.e., counterclockwise rotation, the tension spring H2 may restrict clockwise rotation of the rotation bracket H5 around the rotation shaft H4, and in order to more reliably fix the rotation bracket H5, the protection device H may further include a dustbin press block H6 provided on the sub-frame 2, the dustbin press block H6 may be used in a clockwise rotation position of the rotation bracket H5 around the rotation shaft 1, and the rotation bracket H is in a certain initial position in the initial rotation position, and the rotation position is in the rotation position of the rotation bracket H1; in the working state, after the lifting device 3 lifts the dustbin 2 along the vertical direction, the dustbin 2 is at the second position or the position between the first position and the second position, because the dustbin pressing block H6 is arranged on the dustbin 2 and can move upwards along with the dustbin 2, at the moment, only the tension spring H2 limits the rotation of the rotating support H5 around the rotating shaft H4 along the clockwise direction, when the rotating support H5 is subjected to the action of external force capable of enabling the rotating support H5 to rotate along the clockwise direction, for example, when the docking equipment presses the rotating support H5 or the rear guardrail H1 towards the middle part of the auxiliary frame 1, the tension spring H2 is stretched to enable the rotating support H5 to rotate clockwise around the rotating shaft H4 to retract inwards, and the rotating support H5 is in the contracted state; when the rotating support H5 is not affected by external force, the rotating support H5 rotates anticlockwise to a position where the limiting block H3 can limit the rotating support H5 to continue anticlockwise rotation under the action of restoring force of the tension spring H2, in addition, the dustbin 2 returns to the first position under the action of the lifting device 3 to enable the dustbin pressing block H6 and the tension spring H2 to limit the rotating support H5 to rotate around the rotating shaft H4 in the clockwise direction, the rotating support H5 is in an initial state of extending out of the auxiliary frame 1 under the combined action of the tension spring H2, the limiting block H3 and the dustbin pressing block H6, and the dustbin returns to a normal state.
