Abstract
The utility model provides a square sieve vibration exciter that sways, includes the box, and the box middle part is through mounting bracket fixedly connected with casing, rotates through the bearing in the casing and is connected with the center pin, installs the driven pulleys on the center pin, and center pin upper portion and lower part are installed balancing weight and lower balancing weight through the mounting panel respectively, go up the balancing weight and lie in both sides and symmetry setting about the casing down with lower balancing weight, go up the balancing weight and the balancing weight structure is the same with weight down. The utility model discloses simple structure, job stabilization, can greatly reduce wearing and tearing, long service life.
Description
Technical Field
The utility model belongs to the technical field of the sieve that sways, especially, relate to a square sieve vibration exciter that sways.
Background
The exciter is a device attached to some machines and equipments for generating exciting force, and is an important part for utilizing mechanical vibration. The vibration exciter can make the excited object obtain a certain form and magnitude of vibration quantity, so as to make vibration and strength test for object or make calibration for vibration testing instrument and sensor. The vibration exciter can also be used as an exciting part to form a vibrating machine for realizing the work of conveying, screening, compacting and molding materials or objects, tamping soil gravels and the like. The vibration exciter that adopts in the current square rocking sieve, the balancing weight on it is usually concentrated and installs on the vibration exciter axle, at the in-process of operation, because the weight of balancing weight self can hang down, and the atress is inhomogeneous, and the operation is unstable, consequently to the requirement of installing the balancing weight than higher to the wearing and tearing of operation to vibration exciter axle and bearing are great.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the weak point among the prior art, provide a simple structure, job stabilization, can greatly reduce wearing and tearing, long service life's square swinging screen vibration exciter.
In order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides a square sieve vibration exciter that sways, includes the box, and the box middle part is through mounting bracket fixedly connected with casing, rotates through the bearing in the casing and is connected with the center pin, installs the driven pulleys on the center pin, and center pin upper portion and lower part are installed balancing weight and lower balancing weight through the mounting panel respectively, go up the balancing weight and lie in both sides and symmetry setting about the casing down with lower balancing weight, go up the balancing weight and the balancing weight structure is the same with weight down.
The driven belt wheel is arranged at the lower end part of the central shaft.
The upper balancing weight and the lower balancing weight are correspondingly connected in series by a plurality of sheet blocks through mounting bolts and are mounted on the mounting plate.
An upper bearing and a lower bearing are arranged between the shell and the central shaft.
And a plurality of reinforcing blocks are fixedly connected between the mounting frame and the shell along the circumferential direction.
Adopt above-mentioned technical scheme, the utility model discloses when the work is used, adopt external motor to drive the center pin through driven pulleys and rotate, the center pin drives the balancing weight and rotates with balancing weight down in step to produce the vibration, the utility model discloses a go up balancing weight and balancing weight down, form double-deck eccentric vibration, greatly dispersed the effort of balancing weight to the center pin, improved the stability of operation greatly, also reduced the wearing and tearing of bearing on the center pin simultaneously, improved its life.
