The invention discloses stable garbage treatment equipment. The equipment comprises a pedestal and a compressor fixedly arranged at the top of the pedestal. A lifting slide groove is formed in the bottom surface of the compressor. A lifting slide block is connected into the lifting slide groove in a sliding fit mode. A through groove extending left and right is formed in the lifting slide block. Acavity is formed in the middle of the inner top wall of the through groove in a communication mode. A rotating sphere is connected into the cavity in a matched mode. An arc-shaped gear ring is arranged on the rotating sphere. The rear side of the rotating sphere is connected with a first motor in a matched mode. The outer surface of the first motor is arranged in the position, on the rear side ofthe cavity, in the lifting slide block and connected in a fixing fit mode. A supporting arm extending left and right is connected into the through groove in a sliding fit mode. The extending tails ofthe left and right sides of the supporting arm extend out of the left and right side surfaces of the lifting slide block correspondingly. The stable garbage treatment equipment is simple in structureand convenient to operate, and the garbage compressing effect is improved.
