Garbage can lifting device with weighing function

The invention discloses a garbage can lifting device with a weighing function, and belongs to the technical field of garbage trucks. The garbage can lifting device comprises a lifting mechanism, a pressing plate mechanism, a turnover mechanism and a weighing mechanism, the weighing mechanism comprises a weighing plate, and a clamping block used for being conveniently connected with a garbage can in a matched and clamped mode is installed on the weighing plate; and a pressure sensor is installed below the weighing plate, a spring used for jacking the pressing plate mechanism along with the weighing mechanism is further installed on the weighing plate, and the spring can enable the pressing plate mechanism to be jacked up in the process that the garbage can is lifted along with the weighing mechanism, so that the situation that weighing is affected due to the fact that the pressing plate mechanism presses the garbage can is avoided. The problem that in the prior art, weighing of the garbage can is not accurate
