Description
Technical Field
[0001] A pneumatic vibrator equipped with an exciting force regulating device belongs to the technical field of engineering machinery. Background Art
[0002] With the sustained and rapid development of my country's national economy, the demand for pneumatic vibrators in all walks of life has continued to increase, especially in the fields of water conservancy and hydropower, underground mining, and prefabricated concrete components. Pneumatic vibrators are divided into two types: pneumatic insertion vibrators and pneumatic external vibrators, of which pneumatic external vibrators are more widely used. Pneumatic external vibrators use compressed air as the power source, and remove pores in the concrete mixture through vibration and compaction, thereby improving the strength of the concrete structure and shortening its solidification time. They are particularly suitable for working conditions with explosion-proof requirements. Our company is a professional enterprise that produces vibration machinery, and develops and produces various series of vibration machinery such as electric, motorized, and pneumatic. In terms of pneumatic external vibrators, the first pneumatic external vibrator we developed was awarded a national patent with patent number 200920088382.2; later we improved it and added a leak-proof structure, which also obtained a national patent with patent number 201920122945.9. Since then, we have improved the anti-leakage structure and obtained the national patent for "a pneumatic vibrator with improved anti-leakage mechanism", patent number 202120594443.3; we have also improved the air intake structure and obtained the national patent for "a pneumatic external vibrator with improved air intake structure", patent number 202321059088.5. Technological innovation is endless. In recent years, we have found that the pneumatic vibrator has the disadvantages of not being able to adjust the exciting force according to the needs of the on-site working conditions during use. It is urgent to conduct in-depth research and work hard to solve this problem, and innovate and develop a pneumatic vibrator that can easily adjust the exciting force. Summary of the invention
[0003] The purpose of the present invention is to innovatively develop a pneumatic vibrator that can conveniently adjust the exciting force to meet the urgent needs of water conservancy and hydropower, underground mining, precast concrete components and other fields for pneumatic vibrators.
[0004] The technical solution of the present invention is: a pneumatic vibrator composed of an inner rotor, an outer rotor, a shaft, a steel ball, an air pipe quick connector, an air inlet end cover, a casing, a fan blade, an air outlet end cover, and an exciting force regulating device, a plurality of rows of holes are arranged between the axial groove and the blind hole of the shaft, a circular hole is arranged at the opposite position of the axial groove, and the air pipe quick connector is connected to the shaft at the left end of the shaft hole by a thread; notches are arranged at the inner circumference of the shaft hole of the air inlet end cover and the air outlet end cover and at the opposite position of the circular hole of the shaft, respectively, and steel balls are arranged at the opposite position of the circular hole of the shaft and the air inlet end cover and the air outlet end cover; a screw hole is arranged at the center of the air outlet end of the shaft, a gap is left between its end face and the outer end face of the air outlet end cover, a screw hole is processed at the outer end of the air outlet hole of the air outlet end cover, and an exciting force regulating device is installed.

[0009] The details and working process of the present invention are described in detail in conjunction with the drawings of the present invention. Obviously, the described embodiment is only one embodiment of the present invention, not all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention. A pneumatic vibrator consisting of an inner rotor 1, an outer rotor 2, a shaft 5, a steel ball 6, an air pipe quick connector 7, an air inlet cover 8, a casing 9, a fan blade 10, an air outlet cover 11, and an exciting force regulating device 12. A plurality of rows of holes are arranged between the axial groove and the blind hole of the shaft 5, a circular hole is arranged at the opposite position of the axial groove, and the air pipe quick connector 7 is connected to the shaft 5 at the left end of the axial hole by a thread; the inner circumference of the axial hole of the air inlet cover 8 and the air outlet cover 11 and the corresponding position of the circular hole of the shaft 5 are respectively provided with notches, and the circular hole of the shaft 5 and the corresponding positions of the air inlet cover 8 and the air outlet cover 11 are respectively provided with steel balls 7; a screw hole is arranged at the center of the air outlet end of the shaft 5, and a gap is left between its end face and the outer end face of the air outlet cover 11, a screw hole is processed at the outer end of the air outlet hole of the air outlet cover 11, and an exciting force regulating device 12 is installed. In addition, the pneumatic vibrator uses bolts, washers 3, nuts 4 and bolts to fasten the air inlet cover 8 and the air outlet cover 11 to the housing 9. When working, the air pipe of the air source is inserted into the air pipe quick connector 7. The sealing ring in the air pipe quick connector 7 has a sealing effect, and the locking wing has a locking effect. The air pipe quick connector 7 and the pneumatic external vibrator are locked quickly and reliably. The compressed air enters the blind hole of the shaft 5 from the air pipe quick connector 7, blows the inner rotor 1 through the row holes and the fan blades 10 thereon, and then blows the eccentric outer rotor 2 through the air inlet pit on the air inlet cover 8 to rotate around the inner rotor 1, generating vibration, vibrating and compacting the concrete, eliminating the pores in the concrete mixture, improving the strength of the concrete structure, and shortening its solidification time. The air flow is discharged through the air outlet pit on the air outlet cover 11. Since there is a gap between the left end face of the shaft 5 and the outer end face of the outlet cover 11, the shaft 5 can be effectively tightened to prevent the shaft 5 from axially moving and causing wear of the steel ball 6, thereby overcoming the looseness of the steel ball 6 in the gap between the circular hole of the shaft 5 and the outlet cover 11 and the gap between the circular hole of the shaft 5 and the inlet cover 8, and effectively improving the sealing effect of the pneumatic vibrator. The exciting force adjustment device 12 is composed of a plug installed on the outlet hole of the outlet cover 11. There are several outlet holes. The number of plugs installed is negatively correlated with the amount of air outlet and the size of the exciting force of the vibrator. The more plugs installed, the less air outlet and the smaller the exciting force of the vibrator; conversely, the fewer plugs installed, the more air outlet and the larger the exciting force of the vibrator. We have clearly stated the number of installed plugs and the exciting force value of the vibrator in the product manual. Users of this pneumatic vibrator can easily choose according to the actual needs of the construction site. Compared with the previous inability to adjust the exciting force of the vibrator, it plays a significant role in improving the vibration compaction effect of concrete, shortening its solidification time, and increasing the strength of the concrete structure.The beneficial effects of the present invention are: solving the long-standing problem that the exciting force of the vibrator cannot be adjusted during use, greatly improving the vibration compaction effect, enhancing the strength of the concrete structure, convenient adjustment, simple structure, strong adaptability, comfortable operation, reliable operation, easy maintenance, high production efficiency, good vibration effect, long service life, wide application range, novel design, reasonable structure, safety and reliability.
