Tamping device with adjustable weight

The invention relates to a tamping device with the adjustable weight. According to the punning device with the adjustable weight, the problems that the tamping weight of a tamping device is not adjustable, the applicability is narrow, and the operation is tedious and complicated are effectively solved. According to the technical scheme, placement plates arranged at intervals are arranged on a trolley, three sets of counterweight rods are arranged between the placement plates, and the counterweight rods are mutually matched and in a designated state, tamping devices are slidably connected to the placement plates in the vertical direction, when the tamping devices are driven to be lifted to different heights by a motor, the counterweight rods at different heights can be unlocked and fixedlyconnected with the tamping devices, and the tamping operation is conducted to the ground by the counterweight rods and the tamping devices, thus the effect of changing the tamping weight is achieved,the degree of automation o
