Abstract
A kind of vibratory sieve damping unit; solve the problem of significantly being waved when vibratory sieve is shut down; it includes vibrating spring seat, stationary spring seat and helical spring; the upper end of helical spring is sleeved on vibrating spring seat; the lower end of helical spring is sleeved on stationary spring seat, and it is characterized in that, there is a cylinder in helical spring; there is a damping body on the top of cylinder, damping body is located in vibrating spring seat；The utility model has the advantage of; damping body is set in vibrating spring seat, although there are huge lateral impact forces during shutdown, but the rocking tendency of vibrating spring seat can be damped the limitation of body; the kinetic energy of sieve nest is set to decay rapidly; the problem of sieve nest is acutely significantly waved when avoiding shutdown, reduces the damage of helical spring, extends the service life of helical spring; simultaneously; because damping body is nonmetallic materials, the noise for producing impact is also small a lot, and is conducive to extending the service life of complete machine.
Description
Technical field
The utility model belongs to a kind of flexible member, more particularly to a kind of vibratory sieve used in processing of farm products equipment
Damping unit.
Background technology
In processing of farm products, be often required to carry out pending material with vibratory sieve classification processing, or to shelling after
Material carry out sorting process, remove impurity therein, obtain pure material.Classification or sorting generally using vibratory sieve come
Complete, vibratory sieve is mainly made up of sieve nest, vibrating motor, flexible member and frame etc., flexible member generally uses 4, install
Between frame and sieve nest, vibrating motor is arranged on the bottom of sieve nest, drives sieve nest vibration, and flexible member plays support sieve nest
Effect, and it is of reciprocating vibration to ensure that sieve nest is realized in frame.Described flexible member is by vibrating spring seat, stationary spring seat and spiral shell
Revolve spring to constitute, vibrating spring seat, the shape of stationary spring seat are annular, and vibrating spring seat is located at the bottom of sieve nest, quiet
Only spring base is located in frame, and the upper end of helical spring is sleeved on vibrating spring seat, and the lower end of helical spring is sleeved on static
On spring base, so that sieve nest is supported in frame.This vibratory sieve is when starting to start, because sieve nest is from inactive state
Come, without inertia force, therefore, the phenomenon that sieve nest is not swung significantly；Into after working condition, the vibrational state of sieve nest be also with
Based on upper and lower vibration, oscillation crosswise is smaller, the phenomenon that sieve nest is not also swung significantly, and the external force suffered by helical spring is also at it
In the range of bearing；And when vibratory sieve is shut down, because sieve nest obtains larger kinetic energy in vibration, under speed is suddenly slow
When coming, the upper and lower vibration of sieve nest can progressively weaken, oscillation crosswise then can not flat Heng, and helical spring bears horizontal force
Ability is again very poor, and at this moment sieve nest will occur violent transverse direction and significantly wave, the transversely acting huge to helical spring generation
Power, causes the impact of transfiniting to helical spring, and this damage to helical spring is very big, is the main cause that helical spring is damaged,
It is also a great problem for perplexing grain processing enterprise for many years.Moreover, this wave can make whole equipment all suffer damage, it is adjoint
To wave and can also produce huge noise, operating personnel are caused with certain psychological pressure.
The content of the invention
The problem of the purpose of this utility model is and overcomes above-mentioned existing flexible member to exist can eliminate sieve nest there is provided one kind
The vibratory sieve damping unit significantly waved during shutdown.
The utility model includes vibrating spring seat, stationary spring seat and helical spring, and the upper end of helical spring, which is sleeved on, to shake
On flexible spring seat, the lower end of helical spring is sleeved on stationary spring seat, and it is characterized in that, there is a post in helical spring
Body, there is a damping body on the top of cylinder, and damping body is located in vibrating spring seat, and vibrating spring seat is limited using damping body
Transverse movement, is significantly waved when preventing sieve nest from shutting down.
There is a spacing N between the internal diameter of external diameter and the vibrating spring seat of described damping body, to ensure not influence sieve nest
Normal vibration during work.
The utility model has the advantage of set damping body in vibrating spring seat, although there is huge transverse direction during shutdown
Impulsive force, but the rocking tendency of vibrating spring seat can be damped the limitation of body, the kinetic energy of sieve nest is decayed rapidly, it is to avoid to stop
The problem of sieve nest is acutely significantly waved during machine, reduces the damage of helical spring, extends the service life of helical spring, together
When, because damping body is nonmetallic materials, the noise for producing impact is also small a lot, and is conducive to extending the use longevity of complete machine
Life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, the utility model includes vibrating spring seat 1, stationary spring seat 5 and helical spring 4, described vibration
Spring base 1 is welded on the bottom of sieve nest, and the upper end of helical spring 4 is sleeved on vibrating spring seat 1, the lower end set of helical spring 4
On stationary spring seat 5；There is a cylinder 3 in helical spring 4, cylinder 3 is metal rigidity body, stationary spring seat 5 and post
Body 3 is welded in frame, there is a damping body 2 on the top of cylinder 3, and damping body 2 is fixed together with cylinder 3, damping body 2
In in vibrating spring seat 1, damping body 2 uses nonmetallic materials, can be hit using materials such as nylon, plastic cement and rubber with reducing
Impulsive force and noise when hitting, the transverse movement of vibrating spring seat 1 are limited using damping body 2, when prevention sieve nest is shut down significantly
Wave；There are a spacing N, spacing N to be more than what sieve nest vibrated between the internal diameter of external diameter and the vibrating spring seat of described damping body
Amplitude, is 1.2 ~ 1.5 times of sieve nest vibration amplitude, to ensure not influence normal vibration when sieve nest works.
Claims (2)
1. a kind of vibratory sieve damping unit, it includes vibrating spring seat, stationary spring seat and helical spring, the upper end of helical spring
