Description
Technical field
The utility model relates to the dampening apparatus field of the industry vibratory sieves such as metallurgy, mine, oil, relates in particular to a kind of vibratory sieve dual spring dampening apparatus.
background technology
Vibration insulating system is the key position of vibratory sieve, if process bad, can cause load excessive, cause foundation failure, on the other hand, vibratory sieve resonance, can make screen(ing) machine produce can not to give motion, cause screen(ing) machine mechanism and supporting to damage, and vibration insulating system is the key factor of impact resonance, at present, in the time of design vibration insulating system, generally start with from load aspect both at home and abroad, consider less for resonance factor, cause vibratory sieve to go wrong, this just needs a kind of shaker performance that improves badly, reduces the dampening apparatus of resonance.
summary of the invention
In order to overcome the above problems, the utility model provides a kind of vibratory sieve dual spring dampening apparatus, and it is simple in structure, and reliable operation can effectively reduce resonance amplitude, improves shaker performance.
The technical solution of the utility model is: a kind of vibratory sieve dual spring dampening apparatus is provided, it is made up of outer spring, inner spring, locating piece, lower spring cup and upper spring seat, two locating pieces are installed respectively on lower spring cup and upper spring seat, two inner springs are arranged on respectively on two locating pieces of upper spring seat, two outer springs are arranged on respectively on two locating pieces of lower spring cup, two inner springs are inserted in respectively in two outer springs, upper spring seat is fixed on vibratory sieve, and locating piece adopts polyurethane elastomeric materials to form.
Compared with prior art, the beneficial effects of the utility model are: improved the safety and stability of vibratory sieve, increased the service life, improved the economic benefit of applying unit.
accompanying drawing explanation
Further the utility model is illustrated with reference to the accompanying drawings below
Accompanying drawing is structure chart of the present utility model;
Shown in figure: 1, outer spring, 2, inner spring, 3, locating piece, 4, lower spring cup, 5, upper spring seat, 6, vibratory sieve.
The specific embodiment
Further the utility model is illustrated according to the specific embodiment and accompanying drawing below:
As shown in the figure, a kind of vibratory sieve dual spring dampening apparatus, it is made up of outer spring 1, inner spring 2, locating piece 3, lower spring cup 4 and upper spring seat 5, it is characterized in that installing respectively on lower spring cup 4 and upper spring seat 5 two locating pieces 3, two inner springs 2 are arranged on respectively on two locating pieces 3 of upper spring seat 5, two outer springs 1 are arranged on respectively on two locating pieces 3 of lower spring cup 4, two inner springs 2 are inserted in respectively in two outer springs 1, upper spring seat 5 is fixed on vibratory sieve 6, and locating piece 3 adopts polyurethane elastomeric materials to form.
In the time that reality is used, vibratory sieve is placed on by four support springs, the decrement of four support springs is basically identical, due to inner spring 2 and the synergy of outer spring 1, can effectively reduce resonance amplitude, locating piece 3 adopts polyurethane elastomeric materials to form, and can reduce noise.
The above is embodiment of the present utility model, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All any modifications of doing within spirit of the present utility model and principle, be equal within replacement, improvement etc. all should be contained in claim scope of the present utility model.
