Description

Technical Field

[0001] The utility model belongs to the technical field of pneumatic vibrators, in particular to a novel pneumatic vibrator. Background Art

[0002] A pneumatic vibrator is a vibration source that uses high-pressure gas discharged from an air compressor as a power source to generate vibrations. Existing pneumatic vibrators usually include a shell with an exhaust hole. When in use, the air can be directly exhausted into the air through the exhaust hole. However, when the existing pneumatic vibrators exhaust air to the outside, the gas exhaust speed is usually fast. Therefore, when used in some places such as construction sites and dust workshops, dust is sometimes easily blown up, causing the dust to float and pollute the working environment. Therefore, there are still shortcomings and deficiencies in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the implementation mode of the present invention is further described in detail below with reference to the accompanying drawings.

[0028] like Figures 1 to 8 As shown, the utility model provides a novel pneumatic vibrator, including a base 8 and a horizontally distributed inner sleeve 3. Specifically, when in use, the utility model can be installed on various equipment that requires vibration through the base 8 and used as a vibration source; an air inlet 11 and an exhaust hole 12 are respectively opened on the two end surfaces of the inner sleeve 3, that is, the air inlet 11 and the exhaust hole 12 are located at the two ends of the inner sleeve 3; and when in use, the air inlet 11 can be connected to an air intake pipe to connect to an air compressor; and a fixing block 4 is coaxially installed in the end of the inner sleeve 3 away from the exhaust hole 12, and a central shaft 5 with an axial diameter smaller than the inner diameter of the inner sleeve 3 is coaxially installed between the end of the fixing block 4 away from the air inlet 11 and the inner sleeve 3, and the exhaust hole 12 is located outside the circumference of the central shaft 5; and the fixing block 4 is also sleeved A spiral strip 6 is provided which is matched with the inner diameter of the inner sleeve 3, and a spiral channel 13 which is connected with the air inlet hole 11 can be formed between the spiral strip 6 and the inner sleeve 3, and the end of the spiral channel 13 which is away from the air inlet hole 11 is connected with the gap between the central axis 5 and the inner sleeve 3, and an impact ring 10 which can collide with the inner sleeve 3 is sleeved on the central axis 5. Specifically, the inner diameter of the impact ring 10 is much larger than the axial diameter of the central axis 5, and when the impact ring 10 is eccentrically arranged relative to the central axis 5, the impact ring 10 can collide with the inner sleeve 3; when in use, when the high-pressure gas discharged from the air compressor enters the spiral channel 13 through the air inlet hole 11, a spiral airflow can be formed, and then the spiral airflow can blow the impact ring 10 to reciprocate and collide with the inner sleeve 3 in the inner sleeve 3 to generate vibration.

[0029] In addition, a casing 1 is installed on the base 8 and is coaxially arranged with the inner sleeve 3. One end of the casing 1 is open and sleeved on the inner sleeve 3, and the other end of the casing 1 is arranged near the exhaust hole 12 and coaxially opened with an exhaust port 2. When in use, the high-pressure gas in the inner sleeve 3 can be discharged outwardly through the exhaust hole 12 and the exhaust port 2 in turn; the exhaust hole 12 and the exhaust port 2 are staggered, that is, the exhaust hole 12 is located outside the circumference of the exhaust port 2; and there is a gap between the end of the casing 1 where the exhaust port 2 is opened and the inner sleeve 3 to form a buffer chamber 15. In this way, when in use, the speed of the high-pressure gas discharged through the exhaust hole 12 can be slowed down, and then the gas is exhausted outwardly through the exhaust port 2, thereby reducing the occurrence of dust blown up by the discharged high-pressure gas, so as to avoid dust dispersion and improve the working environment.

[0030] The specific arrangement of the spiral channel 13 communicating with the air inlet 11 is as follows: Figure 2 , Figure 3 and Figure 5As shown, one end of the central axis 5 close to the fixed block 4 passes through the fixed block 4 and is connected to the inner sleeve 3. The air inlet hole 11 is a groove opened on the central axis 5. The air inlet hole 11 can be set to be coaxial with the central axis 5 but not pass through the central axis 5; and the outer wall of the central axis 5 is also provided with a plurality of first air inlet holes 51 distributed equidistantly and connected to the air inlet hole 11 along the circumferential direction of the central axis 5, and the first air inlet holes 51 are parallel to the radial direction of the central axis 5; the outer wall of the fixed block 4 is provided with a plurality of first air inlet holes 51 distributed equidistantly and connected to the air inlet hole 11 along the circumferential direction of the fixed block 4 The number of air holes 51 is equal and their positions are relative to the second air inlet holes 41. The second air inlet holes 41 are parallel to the radial direction of the fixed block 4. An air inlet channel 16 is formed between the second air inlet holes 41 and the corresponding first air inlet holes 51. The air inlet channels 16 are located on the side of the spiral strip 6 away from the exhaust hole 12 and are all connected to the spiral channel 13. Specifically, there are several air inlet channels 16. When in use, each air inlet channel 16 can allow the high-pressure gas discharged from the air compressor to enter the spiral channel 13 to form a spiral airflow.

[0031] Further, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, one end of the inner sleeve 3 with the air inlet 11 is open and coaxially mounted with the end cover 7, the fixing block 4 is mounted on the inner side of the end cover 7, and the end of the center shaft 5 close to the fixing block 4 passes through the fixing block 4 and the end cover 7 in sequence and is connected to the end cover 7. Specifically, at this time, during assembly, after the impact ring 10 is sleeved on the center shaft 5, the end of the center shaft 5 away from the fixing block 4 can be assembled with the inner sleeve 3 first, and then the fixing block 4 and the end cover 7 are sleeved on the center shaft 5 together. Then, when the installation is in place, the center shaft 5 and the end cover 7, the end cover 7 and the inner sleeve 3 are assembled and fixed in turn, and finally the inner sleeve 3 is inserted into the casing 1 and in place, and then the inner sleeve 3 is assembled and fixed with the casing 1, so as to facilitate the assembly operation.

[0032] Further, such as Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a receiving hole 17 is coaxially provided at one end of the inner sleeve 3 where the exhaust hole 12 is provided, and the aperture of the receiving hole 17 is larger than the diameter of the central axis 5. A positioning plate 18 matching the receiving hole 17 is installed at one end of the central axis 5 close to the receiving hole 17. At this time, during assembly, after installing the impact ring 10, the end of the central axis 5 close to the fixing block 4 can be successively penetrated through the fixing block 4 and the end cover 7, and then assembled and fixed with the end cover 7. Then, the central axis 5, the fixing block 4 and the end cover 7 are inserted into the inner sleeve 3 together, until the positioning plate 18 is located in the receiving hole 17, and the end cover 7 can be installed in place. Then, after the end cover 7 is assembled and fixed with the inner sleeve 3, the assembly and fixation of the inner sleeve 3 and the casing 1 are completed, thereby making the assembly operation more convenient. In addition, the exhaust hole 12 is provided on the positioning plate 18 to facilitate the processing of the exhaust hole 12.

[0033] Further, such as Figure 2 , Figures 3 to 6 As shown, there are multiple exhaust holes 12, and the multiple exhaust holes 12 are evenly distributed along the circumference of the positioning plate 18. Specifically, each exhaust hole 12 is staggered with the exhaust port 2. By providing multiple exhaust holes 12, exhaust can be facilitated.

[0034] Further, such as Figure 2 and Figure 3 As shown, a limiting groove 42 is coaxially provided at one end of the fixing block 4 away from the end cover 7, and a limiting plate 9 matched with the limiting groove 42 is mounted on the central axis 5, so that the relative position between the fixing block 4 and the central axis 5 can be easily determined during assembly for easy assembly.

[0035] Further, such as Figures 1 to 3 , Figure 6 and Figure 7 As shown, both the air inlet 11 and the exhaust port 2 are installed with an air pipe threaded joint 19. Specifically, by installing the air pipe threaded joint 19 on the air inlet 11, it is convenient to connect an air inlet pipe to the air inlet 11; and by installing the air pipe threaded joint 19 on the exhaust port 2, it is convenient to connect an exhaust pipe to the exhaust port 2, and then the end of the exhaust pipe away from the exhaust port 2 can be installed in a position away from dust to avoid dust dispersion.

[0036] Further, such as Figure 7 As shown, the housing 1 and the base 8 are connected by connecting bolts 14 . Specifically, there are multiple connecting bolts 14 , and they are countersunk bolts, so that the housing 1 can be easily assembled and disassembled on the base 8 .

[0037] Further, such as Figure 7 and Figure 8 As shown, the outer bottom surface of the casing 1 and the top surface of the base 8 are both flat, or a groove matching the bottom of the casing 1 can be opened on the top surface of the base 8, so that the casing 1 can be easily placed on the base 8 during assembly.

[0038] Furthermore, both ends of the base 8 extend horizontally to the outside of the casing 1 and are provided with mounting holes 81, so that when in use, bolts or other connecting parts can be passed through the mounting holes 81 to facilitate the installation of the utility model on the equipment that needs to vibrate.
