The invention discloses an earth block punching device and belongs to the technical field of punching machining devices. The earth block punching device comprises a rack, a telescopic rod and an electric hand drill, wherein the telescopic rod is vertically fixed to the rack, and the electric hand drill is vertically fixed to the telescopic rod; the earth block punching device is characterized in that the earth block punching device further comprises an actuator used for driving the telescopic rod to stretch out and draw back, and the actuator comprises an actuating mechanism, an adjusting mechanism and a control mechanism which are connected with the telescopic rod; and the actuating mechanism and the adjusting mechanism are connected with the control mechanism correspondingly. According to the earth block punching device, punching work is automatically completed by means of the method that the electric hand drill is controlled through the actuator, stability is good, and a drill bit can be effectively prevented from being broken off; and meanwhile, the labor strength of a worker is reduced, and working efficiency is improved.
