The present invention relates to an air pre-cleaner for an internal combustion engine, and more particularly, to an air pre-cleaner for an internal combustion engine in which a cap can be disassembled to remove impurities of an internal driving body.

In general, when the internal combustion engine is operated, impurities such as dust, sand or snow are introduced into the gas or air introduced into the engine, so it is necessary to remove them, and to remove these impurities, precleaners and air cleaners In general, the energy cleaner is installed near the engine or under the bonnet, and the precleaner is installed outside the bonnet to primarily remove impurities from the air entering the air cleaner. However, conventional precleaners can be classified into two types, cylindrical and turbo type. Among them, the cylindrical has no disassembly of the cap, and when the bearing of the internal drive wears, the entire assembly needs to be replaced. There was a problem that can not be removed even when impurities are inserted in the. In addition, the turbobore had a drawback that the appearance of the air cleaner was too large and heavy so that the supporting method of the air cleaner was robust.

Accordingly, the present invention has been made to solve the above-mentioned drawbacks, and the purpose of the present invention is to provide a cylindrical precleaner that is light in weight and capable of disassembling the cap.

The present invention for achieving the above object is a rotary assembly equipped with a bearing housing and a paddle and an impeller is installed at the upper end of the pipe which is the passage of air flowing into the air cleaner, the outer ring of the rotary assembly is a cylindrical inner ring The inner ring is provided with a vane, while the outer ring of the inner ring is coupled by a bolt to be detachable. In addition, the rotation assembly is coupled to the removable by the nut is not only possible to replace it when the bearing wear, it is possible to extend the life of the precleaner because it can remove the impurities when the rotation assembly is stuck.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the rotating assembly is provided with a bearing housing 2, a shaft 3, a paddle 4, and an impeller 5 at the center of the upper end of the pipe 1, which is a passage of air flowing into the air cleaner. (6) is installed, the outside of the rotary assembly (6) is provided with a cylindrical inner ring (7), the vane (8) to guide the air between the inner ring (7) and the pipe (1) On the other hand, the outer ring of the inner ring (7) to the inner ring (7) and the cap (9) to cover the rotary assembly (6) is detachable to the inner ring (7) by the bolt 10 Is coupled to In the position facing the paddle 4, an outlet 11 as shown in FIG. 2 is formed, and the rotary assembly 6 is detachable and is coupled by a nut 12, and a pipe The lower end of (1) has a structure in which a slot 13 is provided to facilitate engagement with the air cleaner.

Therefore, in the cylindrical precleaner configured as described above, as the engine operates, the pressure inside the pipe 1 decreases so that air flows in the A direction, and the air flows in the B direction (ie, toward the air cleaner) through the pipe 1. As it flows out, the impeller 5 and the paddle 4 rotate. At this time, as the impeller 5 and the paddle 4 rotate, more air flows in the A direction, and the introduced air is guided by the vanes 8, and impurities are pushed toward the inner wall of the cap 9 by centrifugal force. By the rotational force of the paddle 4 is discharged to the outside (in the direction of C of FIG. 2) through the outlet 11, while being discharged primarily (in the direction of B of FIG. 1).

Therefore, in the present invention, the cap 9 is detachable to the inner ring 7 by the bolt 10, and the impeller 5 is also detachable by the nut 12. When this is inserted, this impurity can be removed and the bearing can be replaced with a new one even when the bearing is worn, thereby extending the life of the precleaner.

Claims (1)

At the upper end of the pipe (1) a rotating assembly (6) is provided with a bearing housing (2), a paddle (4) and an impeller (5), and a cylindrical inner ring (7) outside the rotating assembly (6). In the cylindrical precleaner having a vane (8) between the inner ring (7) and the pipe (1), the rotary assembly (6) is coupled by a nut (12) to be detachable. And, the inner ring (7) and the cap (9) is an air pre-cleaner for an internal combustion engine, characterized in that coupled by the bolt 10 to be separated from each other.
