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

Pneumatic shock generator (1) of the present invention is to impart a shock to the dust bag (210) for discharging the dust of the dust collector 200, pneumatic conduit 240 and the pneumatic conduit 240 is mounted on the pneumatic Pneumatic control mechanism 10 for selectively opening and closing the conduit 240 and the main body 230 for generating a pneumatic impact force to the dust collector 200 by the air provided through the pneumatic conduit 240 and the pneumatic control mechanism 10 ) And the like. And the pneumatic shock generator 1 of the present invention is not a control method of the air pressure by the electromagnetic force, the conventional pneumatic conduit 240 and the main body 230 and the like can be used as it is. Only conventionally, the pneumatic control mechanism was operated electronically, but the present invention solves the problems of the electronic structure, and a substantial improvement thereof is the pneumatic control mechanism 10.

Therefore, the following description will focus on the pneumatic control mechanism 10 of the present invention, it will be clear that such a pneumatic control mechanism 10 will operate by the interaction of the pneumatic conduit 240 and the main body 230.

The pneumatic control mechanism 10 provided in the pneumatic shock generator 1 of the present invention has a hollow casing 12, as shown in detail in FIG. 2, and the casing 12 has an air inlet 14 at one side. ) And an air outlet port 16 are formed and an air connector 19 to which the pneumatic connector tube 18 is connected to the main body 230 to the other side is formed. The pneumatic conduit 240 is connected to the air inlet 14, and the pneumatic conduit 240 may be provided with an air pressure of approximately 6.0 kg / cm 2. In addition, the air outlet 16 is equipped with a dissipation tube to be described later to distribute the exhaust air to the outside air.

Then, one side of the casing 12 is opened and the cover 22 and the screw 24 are mounted to block the inner space S and the outside air in a sealed state, and the other side of the cover 22 is a pressure adjusting socket ( 26) is configured to screw.

In addition, a flow path changing mechanism 30 is mounted inside the casing 12, and the flow path changing mechanism 30 is movable to the left and right in the inner space S of the casing 12. (32), the spool (32) is provided with a neck portion (32a) having a reduced diameter in the middle portion, and packing (34) between the inner wall of the casing (12) forming the space (S), respectively. This is to have a mounted structure. Then, the pressure adjusting socket 26 which elastically supports the spool 32 to one side by the spring 36 is screwed to one side threaded portion 12a of the casing 12 so that the insertion depth into the casing 12 is increased. One end of the spring 36 is connected to the front end thereof, and the other end of the spring 36 is inserted into one side of the spool 32 so that the spool 32 is stably inserted into the space S. On the other side of the side will always support elastically. The spring 36 is to elastically support the spool 32 at a pressure of about 5.5Kg / cm2 less than that when the air pressure of the pneumatic conduit 240 is about 6.0kg / cm2.

In addition, the first and second air passages T1, T2, and T3 are formed in the casing 12, and the first air passage T1 supports the spool 32. When the spring 36 is tensioned, a flow path is formed which communicates with the inner space S of the casing 12 and the central neck portion 32a of the spool 32 and the air connector 19 at the air inlet 14. The air pressure of the pneumatic conduit 240 is supplied from the air inlet 14 to the main body 230 through the air connector 19, the air pressure of the pneumatic conduit 240 is stored in the main body 230. In this case, the air pressure from the air inlet 14 is to advance the check valve 232 in the body 230 to store the air pressure in the pneumatic storage chamber 234.

The second air flow path T2 allows the air pressure to be transferred from the air inlet 14 through the first air path 40 and the orifice 42 formed toward one end of the spool 32, and the first air flow path. The first and second air passages (40) (45) are formed to form a passage through which the ball check valve (47) and the second air passage (45) are transferred from the furnace (40) to the air connector (19). Are each formed as one hole, the orifice 42 as shown in Fig. 4 is screwed into the first air passage 40, and the ball as shown in Fig. 5 is shown in the second air passage 45. The check valve 47 is screwed. The orifice 42 has a plurality of holes 43a penetrating through the first member 43 having a conical protrusion 43b formed at one side thereof, and a conical protrusion 43b of the first member 43. A conical groove 44a is formed at one side, and has a second member 44 formed through one hole 44b in the center thereof, and the first member 43 and the second member 44 are formed. Are spaced apart at regular intervals such that air flows through the holes 44b of the second member 44 to flow through the plurality of through holes 43a of the first member 43. On the other hand, the ball check valve 47 has a through hole (48a) in the center and the third member 48 and the ball (49) seated in the groove (48b) formed with a conical groove (48b) on one side; And a cylindrical fourth member 50 having a plurality of through holes 50a formed therein, wherein the third and fourth members 48 and 50 can move the ball 49 therebetween. By maintaining the interval therebetween, the flow of air from the hole 48a of the third member 48 to the hole 50a of the fourth member 50 is allowed, The flow of air toward the three members 48 is to be blocked by the ball 49 to perform the function of the check valve 45. The through hole 48a formed in the center of the third member 48 has a larger inner diameter than the through hole 44a formed in the center of the second member 44. This means that the air flow through the ball check valve 45 may be larger than the air flow through the orifice 42, and the process of returning the spool 32 to the initial position can be performed more quickly.

In addition, when the air pressure is transmitted from the air inlet 14 through the first air passage 40 and the orifice 42 in the second air flow path T2, since the air pressure corresponds to 6.0 kg / cm2, The small pressure of the spring 36 of approximately 5.5 kg / cm < 2 > causes the spool 32 to move while blocking the first air passage T1, and at the same time through the second air passage 45 and the ball check valve 47. The air pressure is directed to the air outlet (16).

When the spring 36 supporting the spool 32 is compressed by air pressure through the second air flow path T2, the third air flow path T3 may include a casing 12 at the air connector 19. The inner space (S) of the spool 32 and the central neck portion 32a and the air outlet 16 to form a communication, which is the air pressure through the second air flow path (T2) and the pneumatic connection pipe ( The air pressure of 18) is discharged to the outside of the casing 12, the air pressure of 6.0kg / cm2 which pushed the spool 32 to one side is lowered than the restoring force of the spring 36 of 5.5kg / cm2 When the spool 32 is returned by the spring 36, the air pressure of 6.0 kg / cm 2 stored in the pneumatic storage chamber 234 of the main body 230 is applied to the check valve 232. It pushes to the position and pushes the hammer 238 in the main body 230 to generate an impact force to the dust collector 200. In addition, the air outlet 16 is equipped with a dissipation mechanism 60 for dispersing air when the air in the casing 12 escapes to the outside.

Reference numeral 62 is a screw groove for screwing the orifice 42 and the ball check valve 47 to the first and second air passages 40 and 45.

The present invention configured as described above, as shown in Figure 3a), when the air of 6.0kg / cm2 flows from the pneumatic conduit 240 to the air inlet 14, which is the body through the first air flow path (T1) While storing the pneumatic pressure of 6.0 kg / cm 2 in the 230, and pressurizing one side of the spool 32 through the first air passage 40 and the orifice 42 of the second air flow path (T2), 32) presses the spring 36 to move as shown in Figure 3b). Then, as can be seen in Figure 3b), the first air flow path (T1) is closed, the third air flow path (T3) is opened and introduced into the casing 12 through the second air flow path (T2). Air is discharged to the outside through the third air flow path (T3), and therefore, by the restoring force of the spring 36, the spool 32 immediately returns to its original position, and the main body 230 is 6.0 kg As the air pressure of / cm 2 is reduced, the hammer 238 is advanced to strike the dust collecting equipment 200, and to exit through the front outlet 239 of the main body 230. Therefore, the state of FIG. 3b) is returned to the state of FIG. 3a) and continuously flows from the pneumatic conduit 240 into the first and second air passages T1 and T2 through the air inlet 14. Due to the pneumatic pressure of 6.0kg / cm2 is the spool 32 is to achieve a repetitive operation, the hammer 238 in the body 230 is to continue to hit. The return operation associated with the impact of the hammer 238 in the main body 230 is made by a built-in spring 36, wherein the air pressure flowing through the air inlet 14 is set to 6.0 kg / cm 2 , The pressure by the spring 36 is also set to 5.5kg / cm 2, but the present invention is not limited thereto, and of course, the present invention is operable using the operating principle of the present invention with a pressure condition different from the above.

In addition, the inflow of air through the second air flow path T2 may be adjusted through the orifice 42. It is possible to adjust the amount of air flowing therebetween by adjusting the distance between the conical projection 43b and the conical groove 44a by adjusting the distance of the second member 44 with respect to the first member 43, Therefore, the orifice 42 acts as an air amount regulating valve for adjusting the forward speed of the spool 32. In addition, the pressure adjusting socket 26 may adjust the strength of the force supporting the spool 32 by the spring 36 by adjusting the tension of the spring 36. This increases the tension of the spring 36 when the socket 26 is inserted deeply and decreases the tension when the socket 26 is shallowly inserted.

As described above, according to the present invention, the operation can be easily performed without using a power supply, and a simple structure makes it easy for anyone to install and maintain, and significantly lowers the failure rate by performing mechanical operation instead of electronic. In other words, the improved effect of reducing power demand can be obtained.
