Therefore, when the rotary tube 30 moves up and down along the inner tube 11, the rotary tube 30 is rotated 90 degrees by the upper guide rail 32 and the upper guide rail 33 installed in the inner tube 11 to open and close the hole 34. In order to communicate with the air hole 14 of each air pocket (13) in turn.

One side of the air circulation pipe is preferably provided with a one-way check valve 37 for distributing air only toward the inner pipe (11).

Hereinafter, the operation of the present invention will be described with reference to FIGS. 4 and 5.

The striking device is attached to the outer surface of the hopper through the fixing portion 20 of the bottom.

In this state, when air is supplied through the air supply pipe 18, the air flows into the inner tube 11 installed at the center of the housing 10, and then through the check valve 19 formed along the side wall of the inner tube 11. Each air pocket 13 is distributed and stored in the air pocket 13.

At this time, the rotary tube 30 is lowered along the inner surface of the inner tube 11 while compressing the spring 35 by the pressure of air.

The state in which the rotary tube 30 is lowered is well illustrated in FIG. 4.

When the rotary tube 30 is lowered, the opening and closing hole 34 formed in the rotary tube 30 is lowered than the air hole 14 formed in the inner tube 11, so that the air hole 14 and the opening and closing hole 34 are It is displaced and the air is filled in the air pocket 13.

In this state, when the solenoid valve 21 installed in the air supply pipe 18 is operated to stop the air supply and discharge some air, the rotary pipe 30 has a return force of the elastic spring 35 compressed at the bottom. Soared up by.

At this time, the key 31 installed on the outer surface of the rotary tube 30 is guided by the vertical guide rail 32 to rise vertically in a controlled state, the key 31 is the vertical guide rail ( 32 and the upper guide rail 33 is raised to a position between the opening and closing hole 34 formed in the rotary tube 30 coincides with the air hole 14 of the one side air pocket formed in the inner tube 11 and the rotary tube ( 30) continues to rise and rotate 45 degrees along the upper guide rail 33 installed in the inner tube (11).

Therefore, the air filled in one air pocket 13 is rapidly moved into the rotary tube 30 through the air hole 14 and the opening and closing hole 34 at the time when the air hole 14 and the opening and closing hole 34 communicate with each other. The discharged and discharged air is introduced into the housing 10 to pressurize the piston 15 installed in the housing 10.

As such, the piston 15 is pushed by the air pressure of the one air pocket 13 introduced into the housing 10, and the striking member 16 installed on the piston 15 strikes the hopper.
