Abstract

The invention discloses a drill bit used for forming through holes in flake ice. A rod body of a metal rod is fixedly sleeved with a metal pipe. The bottom end of the metal pipe is fixedly connected with a metal disc. Multiple ring-shaped grooves are formed in the bottom face of the metal disc. A metal cylinder matched with the diameter of the ring-shaped groove is connected in each ring-shaped groove in an inserted manner. Each metal cylinder is of a structure with openings formed in the two ends. The lower opening of each metal cylinder is provided with a circle of teeth. The outer wall of the metal disc is provided with a left screw hole and a right screw hole. The left screw hole and the right screw hole extend to the ring-shaped groove in the innermost layer. A left screw rod is arranged in the left screw hole. A right screw rod is arranged in the right screw hole. The left screw rod and the right screw rod are used for fixing the metal cylinders. According to the drill bit, one metal disc is arranged on a body, the metal cylinders with the different diameters can be connected to the bottom face of the metal disc in an inserted manner according to needs, and the lower openingof each metal cylinder is provided with the teeth. The through holes with the different hole diameters can be formed in the flake ice according to needs only by connecting the drill bit with an electric tool, the holing efficiency is high, and hole bodies are attractive.

Description

technical field [0001] The invention relates to a drill bit for opening holes in flake ice. Background technique [0002] Flake ice machine is a kind of ice machine. According to the water source, it can be divided into fresh water flake ice machine and sea water flake ice machine. Generally, it is an industrial ice machine. Flake ice has no sharp edges and corners, and will not stab frozen objects. It can enter the gap between the objects to be cooled, reduce heat exchange, maintain the temperature of ice, and have a good moisturizing effect. Flake ice has excellent refrigeration effect, large cooling capacity and rapid cooling, so it is mainly used in various large-scale refrigeration facilities, food quick-freezing, concrete cooling and so on. The thickness of flake ice varies, and in some applications, it is necessary to open holes in the flake ice, and the sizes of the holes are also required to be different. At present, the more common method is manual drilling, whi...
