Abstract
The utility model relates to a double-motor-start linkage type resonance screen. The double-motor-start linkage type resonance screen comprises a screen box support, an upper screen box, a lower screen box and a resonance spring, wherein the upper screen box and the lower screen box are supported on the screen box support through supporting springs, and the resonance spring is connected between the upper screen box and the lower screen box. The double-motor-start linkage type resonance screen is characterized in that two driving motors and two eccentric linkage mechanisms are symmetrically arranged on the two sides of the screen boxes, and the driving motors and the eccentric linkage mechanisms on the corresponding sides are connected through transmission mechanisms. The double-motor-start linkage type resonance screen fundamentally solves the problems that an existing resonance screen is high in motor starting power and low in running power, that is, when the resonance screen is started, the two driving motors operate simultaneously and drive the eccentric linkage mechanisms through the transmission mechanisms, and then the upper screen box and the lower screen box are made to conduct reciprocating and opposite vibration; after the resonance screen runs normally, one driving motor is turned off, and then the purpose of saving energy is achieved; meanwhile, the double-motor-start linkage type resonance screen has the advantages of being simple in structure and low in production cost.
Description
Technical field
The utility model relates to screening plant, and particularly a kind of bi-motor starts link-type resonance screens.
Background technology
At present, traditional resonance screens electric motor starting torque with rigidity connecting rod must be greater than the maximum resistance torque that resonant spring produces, cause its starting power large moment, and when resonance screens turn round, only need overcome the power that the damping resistance of resonant spring and compass screen surface material consume when tossed, in normal operation process, electrical consumption power is less.In order to solve traditional problem that resonance screens electric motor starting power is large, operate power is little, generally adopt elastic link formula resonance screens, it comprises upper and lower screen box, support spring, resonant spring, motor and eccentric rod gear, wherein in eccentric rod gear, connecting rod is elastic construction, according to resonance principle, utilize this elastic construction to make the amplitude of resonance screens progressively reach by zero the required amplitude that runs well, thereby subtract low power consumption.But adopt the resonance screens amplitude of said structure extremely unstable, be easy to change with the variation of resonance screens operating mode, based on this, the resonant spring being connected between upper and lower screen box often adopts nonlinear spring, the amplitude of resonance screens is controlled within the specific limits, but arranging of the connecting rod of nonlinear resonance spring and elastic construction all makes resonance screens structure complicated, design difficulty is large, adjust difficulty, increased production cost.
Summary of the invention
The purpose of this utility model is in order to provide a kind of bi-motor simple in structure, that production cost is low to start link-type resonance screens, fundamentally solve the problem that electric motor starting power is large, operate power is little that traditional resonance screens exist, thereby reach energy-conservation object, and reduced design difficulty, adjusted simple.
The technical solution of the utility model is:
A kind of bi-motor starts link-type resonance screens, comprise screen box bearing, utilize support spring to be supported in upper and lower screen box on screen box bearing, to be connected in the resonant spring between upper and lower screen box, it is characterized in that: screen box bilateral symmetry is furnished with two drive motors and two groups of eccentric rod gears, and the drive motors of corresponding side utilizes transmission mechanism to be connected with eccentric rod gear.
Above-mentioned bi-motor starts link-type resonance screens, described upper and lower screen box is respectively equipped with power transmission shaft I and power transmission shaft II, described eccentric rod gear by the eccentric bushing with power transmission shaft I end key connecting, utilize that bearing holder (housing, cover) is loaded on that shell, one end on described eccentric bushing is fixedly connected with described shell, the hinged connecting rod of the other end and described power transmission shaft II end forms, described connecting rod is rigidity connecting rod, the double-amplitude sum of upper and lower screen box equals the offset of the eccentric bushing of twice, so that the amplitude of upper and lower screen box do not change with the change of operating mode, and reduce production costs.
Above-mentioned bi-motor starts link-type resonance screens, and described resonant spring is Hookean spring, to reduce production costs.
Above-mentioned bi-motor starts link-type resonance screens, and the axis of described connecting rod is by the barycenter of described upper and lower screen box, balanced to guarantee resonance screens vibration.
Above-mentioned bi-motor starts link-type resonance screens, and described transmission mechanism is belt gear or yielding coupling.
The beneficial effects of the utility model are:
1, adopt two drive motors, fundamentally solved the problem that electric motor starting power is large, operate power is little that existing resonance screens exist, while starting resonance screens, two drive motors are worked simultaneously, by transmission mechanism, drive eccentric rod gear, and then make upper and lower screen box do reciprocal opposed vibration, resonance screens are turned off a drive motors after running well, and reach energy-conservation object;
2, the power of two drive motors can be consistent, also can be inconsistent, and the feature choose reasonable large according to resonance screens starting power, operate power is little, thus realize most optimum distribution of resources;
3, each modular construction of resonance screens is simple, effectively reduces production cost more than 30%;
4, each modular construction of resonance screens is simple, and design difficulty is little, adjusts simple.
