Abstract
A kind of vibratory sieve damps adjustable shock-absorbing spring, belongs to vibration screening machinery field.Solve the problems, such as that resonance amplitude is excessive when its metal coil spring occurs frictional noise and starts parking during vibratory sieve work.Including metal coil spring, upper and lower rubber base and damping regulator.At the both ends of metal coil spring, respectively one rubber base of installation, the main body of rubber base are deep into the inside of metal coil spring, steel skeleton are provided with rubber base；The skeleton of upper rubber base is hollow tubulose, and in the pipe of skeleton, equipped with a rubber damping block that can be moved axially along metal coil spring, damping block is connected with axial movement adjusting apparatus.The nut of axial movement adjusting apparatus is fixed in skeleton pipe, and end and the rubber damping block of the adjustment bolt coordinated with it are hinged.Gap a between the end of rubber damping block and the end of lower rubber base is 20~80mm.It is small with running noises, start shooting and shut down the characteristics of stable, the vibratory sieve suitable for sieving various materials.
Description
Technical field
The utility model is the damping means on vibratory sieve, belongs to vibration screening machinery field, is directed primarily to solution and shakes
In making resonance amplitude mistake when frictional noise and vibratory sieve start and stop car occurs for dynamic riddler between its metal coil spring both ends of the surface and bearing
The vibratory sieve of big problem damps adjustable shock-absorbing spring.
Background technology
At present damping means on vibratory sieve using it is most wide be metal coil spring because metal coil spring vibration damping is imitated
Fruit is good, and manufacturing cost is low, simple.But simple metal coil spring has at 2 points not as the damping means of vibratory sieve
Foot：First, two end faces of metal coil spring are grindings into being firm when between the seat ear and bearing of vibratory sieve
Property contact, the noise of interruption can be produced when being worked with vibratory sieve；Second, metal coil spring is when vibratory sieve starts and stops
Resonance amplitude is excessive（5-7 times during normal operation）, and immediate stability and shutdown are unable to, cause the basic dynamic load mistake of support
Greatly.
The content of the invention
The purpose of this utility model is to provide a kind of vibratory sieve and damps adjustable shock-absorbing spring, solves its in vibratory sieve work
Resonance amplitude problems of too when frictional noise and vibratory sieve start and stop car occurs between metal coil spring both ends of the surface and bearing.
The utility model is realized by following measures, including metal coil spring, and upper and lower rubber base and adjustment fill
Put, it is characterized in that：At the both ends of metal coil spring, respectively one rubber base of installation, the main body of rubber base are deep into metal spiral bullet
The inside of spring, steel skeleton is provided with rubber base；The skeleton of upper rubber base is hollow tubulose, in the pipe of skeleton, equipped with one
The individual rubber damping block that can be moved axially along metal coil spring, rubber damping block are connected with axial movement adjusting apparatus.It is described
Rubber damping block on be solidified with metal connecting plate.Moving axially adjusting apparatus is realized by screw bolt and nut, and nut is solid
It is scheduled in skeleton pipe, end and the rubber damping block of the adjustment bolt coordinated with it are hinged.The end of rubber damping block and lower rubber
Gap a between the end of rubber base is 20~80mm.
When vibratory sieve damps the installation of adjustable shock-absorbing spring on the vibrating, two rubber bases seat ear with vibratory sieve respectively
Connected with bearing.Axially gap a, gap a are being left between rubber damping block and lower rubber base in metal coil spring
Adjusted according to the mass of vibration of vibratory sieve and the size of amplitude by adjustment bolt.
The beneficial effects of the utility model are to damp adjustable shock-absorbing spring using vibratory sieve, can effectively reduce vibratory sieve
Noise during work, and in vibratory sieve startup and the resonance region to stop, rubber damping block can make vibratory sieve stable rapidly
And shutdown, improve the overall performance of vibratory sieve.And the size for the load that can be shaken according to the specifications and models and ginseng of vibratory sieve,
Random adjustment gap a, makes its damping reach ideal effect.It is small with running noises, start shooting and shut down the characteristics of stable, be applied to
Sieve the vibratory sieve of various materials.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model, 1 is adjustment bolt in figure, 2 is upper rubber base, 3 is rubber damping
Block, 4 be metal coil spring, 5 be lower rubber base, a is the gap between rubber damping block 3 and lower rubber base 5.
Embodiment
Illustrate one embodiment of the present utility model, including metal coil spring 4 below in conjunction with the accompanying drawings, upper rubber base 2, under
Rubber base 5 and damping regulator.One rubber base, the main body of rubber base are respectively installed at the both ends of the metal coil spring of steel
The inside of metal coil spring 4 is deep into, steel skeleton is provided with rubber base；The skeleton of upper rubber base 2 is hollow tubulose,
In the pipe of skeleton, equipped with a rubber damping block 3 that can be moved axially along metal coil spring 4, rubber damping block 3 is with axially moving
Dynamic adjusting apparatus connection.Metal connecting plate is solidified with rubber damping block 3.It is by bolt and spiral shell to move axially adjusting apparatus
What mother realized, nut is fixed in skeleton pipe, and the end of the adjustment bolt 1 coordinated with it and rubber damping block 3 are be hinged.Vibratory sieve
When damping the installation of adjustable shock-absorbing spring on the vibrating, upper rubber base 1 and lower rubber base 5 the seat ear and branch with vibratory sieve respectively
Seat is connected.Gap a is left between the end of rubber damping block 3 in metal coil spring 4 and lower rubber base 5,
Gap a is adjusted according to the mass of vibration of vibratory sieve and the size of amplitude by adjustment bolt 1, the scope of adjustment 20~80mm it
Between.
