As shown in fig. 9, the first linkage mechanism includes a pressing rod 341, a horizontal sliding bracket 342, a horizontal lever 343, a pressing plate 344, and a first pressing spring 345; the pressing rod 341 is hinged with the base 30, one end of the pressing rod 341 protrudes below the base 30, the other end of the pressing rod 341 is slidably pivoted with a vertical waist-shaped hole arranged on the horizontal sliding support 342 through a pin shaft, the horizontal sliding support 342 is slidably arranged in the base 30 along a direction parallel to the horizontal ejector rod 334, the horizontal lever 343 is hinged in the base 30 along a vertical axis, one end of the horizontal lever 343 is slidably pivoted with a waist-shaped hole which is arranged on the horizontal sliding support 342 and is perpendicular to the horizontal ejector rod 334 through a pin shaft, and the other end of the horizontal lever 343 is slidably pivoted with a waist-shaped hole which is arranged on the pressing plate 344 and is perpendicular to the horizontal ejector rod 334 through a pin shaft; a first radial flange 3341 is arranged on the section of the horizontal top rod 334 positioned at the rear side of the sliding sleeve 301, and the pressing plate 344 is sleeved on the horizontal top rod 334 between the first radial flange 3341 and the sliding sleeve 301; the first pressure spring 345 is sleeved on the horizontal ejector rod 334 between the pressure plate 344 and the sliding sleeve 301; when the pressing rod 341 is pressed by the ground, the pressing plate 344 can be driven to compress the first pressing spring 345, and when the pressing rod 341 loses the ground pressing, the first pressing spring 345 can be ejected backwards to drive the horizontal top rod 334 to move backwards and finally drive the barrel cover 20 to open. The specific working principle of the first linkage mechanism is as follows: when the garbage can is placed on the ground, the pressure lever 341 is pressed by the ground and lifted upwards, at this time, the pressure lever 341 drives the horizontal sliding support 342 to translate towards the front side, the horizontal sliding support 342 drives the horizontal lever 343 to swing, and the horizontal lever 343 drives the pressure plate 344 to translate towards the front side, so that the first pressure spring 345 is compressed; at this time, the movement of the transmission mechanism 33 is not affected, and the pedal 32 can smoothly drive the barrel cover 20 to open; when the trash can is completely lifted from the ground, the pressure lever 341 is released, the first pressure spring 345 loses restraint and is ejected backwards, the horizontal top rod 334 is driven to slide backwards, and finally the can cover 20 is driven to be opened.

In the transferring process of the garbage can, the garbage can is firstly tilted backwards to enable the roller 31 to be stressed, the limiting plate 315 blocks the pressing plate 344 before the garbage can begins to tilt, the situation that the can cover 20 is opened by the second linkage mechanism in the tilting process of the garbage can be avoided, after the garbage can tilts, the roller 31 is stressed and shrinks upwards, the limiting plate 315 can block the first radial flange 3341, at the moment, the can cover 20 cannot be opened even if the pedal 32 is stressed or the can cover 20 is blown by wind, and the fact that the can cover 20 is closed reliably in the transferring process is ensured. In the dumping process of the garbage can, the garbage can is completely separated from the ground, the roller 31 is popped downwards, the limiting plate 315 can completely avoid the pressing plate 344 and the first radial flange 3341, and the second linkage mechanism can be smoothly triggered.
