[0033] Among them, the surface of the connecting rod 1 is provided with a threaded groove, which cooperates with the nut to fix the air disc body 11 to the end of the conveying pipe. The air inlet head 12 and the connecting rod 1 are integrally formed, and an air delivery hole is provided inside the connecting rod 1. The compressed air passes through the air inlet head 12 and the inside of the connecting rod 1, blows out from the lower side of the air disc body 11, and sprays out to the surroundings along the pipe wall. As the air pressure continues to change, the surface of the air disc body 11 generates high-frequency vibration, which promotes the rapid flow of powder and granular materials in the pipe and improves the smoothness of discharge.

[0034] In addition, during the installation process, the air intake head 12 is inserted into the interior of the first connecting pipe 2, and the locking sleeve 3 is pushed upward, and the positioning ball 25 is clamped between the first clamping ring 14 and the second clamping ring 15 with the help of the third support ring 34, and the air intake head 12 is quickly connected to the first connecting pipe 2. At the same time, the sealing gasket 13 is clamped inside the sealing ring 23 and tightly abuts against the surface of the sealing ring 23, effectively improving the sealing of the connection.

[0035] See Figures 3 to 6The second connecting pipe 21 is fixedly connected to the lower end of the first connecting pipe 2, and multiple groups of card grooves 24 are provided on the side wall of the first connecting pipe 2 near the upper end. Positioning balls 25 are clamped inside the multiple groups of card grooves 24, and the first support ring 26 is fixedly connected to the middle position of the outer surface of the first connecting pipe 2. The support spring 27 is sleeved on the outside of the first connecting pipe 2, and the lower end of the support spring 27 abuts against the upper surface of the first support ring 26. The sliding sleeve 31 is fixedly connected to the lower end of the locking sleeve 3, and the sliding sleeve 31 is slidably connected to the first connecting pipe 2. The upper end position of the surface of the sliding sleeve 31 is fixedly connected with a pressure plate 32, and the second support ring 33 is fixedly connected to the middle position of the inner wall of the locking sleeve 3. The second support ring 33 is located on the upper side of the first support ring 26, and the upper end of the support spring 27 abuts against the lower surface of the second support ring 33. The third support ring 34 is fixedly connected to the inner wall of the locking sleeve 3 near the upper end.

[0036] Specifically, in the process of connecting the air inlet head 12 to the air delivery pipe 4, first press the pressure plate 32 downward, and then slide the locking sleeve 3 and the sliding sleeve 31 downward, thereby driving the second support ring 33 and the third support ring 34 to slide downward, pressing the support spring 27, and at the same time making the outer side of the positioning ball 25 lack a limit, then push the first connecting pipe 2 upward and put it on the outer side of the air inlet head 12. As the air inlet head 12 is continuously inserted, the first retaining ring 14 will push multiple groups of positioning balls 25 outward until the first retaining ring 14 moves to the lower side of the positioning ball 25. At this time, the sealing gasket 13 is tightly against the surface of the sealing ring 23, and then release the pressure plate 32. Under the action of 27, the second support ring 33 is pushed upward, thereby driving the locking sleeve 3 to slide upward, and the locking sleeve 3 drives the third support ring 34 to move upward, and the third support ring 34 pushes the positioning ball 25 toward the inner side of the first connecting pipe 2. At the same time, the locking sleeve 3 can be pushed upward by hand, and the auxiliary support spring 27 moves the third support ring 34 upward, pressing the positioning ball 25, so that the inner end of the positioning ball 25 is completely stuck between the first retaining ring 14 and the second retaining ring 15, and at the same time, the sealing gasket 13 is in closer contact with the sealing ring 23, thereby tightly fixing the air intake head 12 inside the first connecting pipe 2, thereby realizing a quick connection between the air intake head 12 and the gas pipeline 4.

[0037] The working principle of the utility model is as follows: by inserting the air inlet head 12 into the interior of the first connecting pipe 2, the locking sleeve 3 is pushed upward, so that the third support ring 34 is stuck on the outside of the positioning ball 25, and then the inner end of the positioning ball 25 is stuck between the first clamping ring 14 and the second clamping ring 15, and then the first connecting pipe 2 and the air inlet head 12 are quickly connected, thereby improving the convenience and efficiency of installation, and supporting the locking sleeve 3 by the support spring 27 to prevent the locking sleeve 3 from shaking, thereby further improving the firmness of the connection.
