Description
Technical field
The utility model relates to a kind of screen flour equipment, especially a kind of Belt Driven by Double Motor formula square plansifter.
Background technology
Square plansifter is the capital equipment of screen flour.Wheat varying in size after grinding system grinds, spotty mixed material, the screening of certain screen route of forming through the multi-deck screen lattice is extracted flour, and other is carried out the equipment of screen and classification than the coarseness material.
Existing square plansifter structure mainly comprises gear frame, drive, sieve storehouse, motor, gets rid of stone roller, power transmission shaft, sieve lattice, hold-down mechanism etc.The gear frame bilateral symmetry is provided with two row's sieve storehouses, and two row's charging apertures are installed at sieve top, storehouse, and two row's charging apertures keep symmetrical, parallel.The square plansifter inner electric machine, power transmission shaft is installed at sieve nest geometric center place, will get rid of stone roller in gear frame inside and be installed on the axle, and drive is installed in the axle upper end, with V-belt motor is connected with power transmission shaft.Consequently get rid of stone roller through the driven by motor power transmission shaft; Make to get rid of to cut or polish jade with an emery wheel and do the high speed rotary motion, the plane rotation motion is done in the sieve storehouse of square plansifter under the effect of getting rid of stone roller inertia force, when motion reaches certain speed; The centrifugal intertia force that material on the compass screen surface produces is enough to overcome the frictional force with compass screen surface; And compass screen surface is done the planar circumferential motion relatively, makes material produce automatic classification, accomplishes the screen to material.
Mostly domestic square plansifter is 6 storehouse formulas, and at present, the demand of 8 storehouse formula square plansifters is just growing.Square plansifter has characteristics such as intensity height, good rigidly, no blowby, mill diagram be flexible, can fully satisfy various flouring technology requirements, for producing sound flour reliable assurance is provided.But its volume is big, and start-up time is long, and the distance of moving about is big, is not suitable for frequent start-stop.Single electric motor starting needs the time longer, and that motor works long hours under overload is more serious to the infringement of motor; The side that the center of gravity deflection of sieve nest is installed motor; So each point is except doing the circular motion with center of gravity on the sieve nest; Also receive the additional moment effect of one-period property variation and twist, so that sieve nest does elliptic motion, simultaneously screen effect and sieve nest life-span are brought certain influence around center of gravity.
Summary of the invention
The utility model is to the defective and the deficiency of the single drive of motor square plansifter that often adopts at present; A kind of novel Belt Driven by Double Motor formula square plansifter is provided; Utilize Belt Driven by Double Motor can reach dynamic equilibrium rapidly, reduce the influence that screen effect and sieve nest life-span is brought because of the sieve nest mass unbalance to greatest extent.
The utility model solves the technical scheme that its technical problem adopted:
This Belt Driven by Double Motor formula square plansifter comprises gear frame, sieve storehouse, sieve lattice, feed inlet and outlet, motor, power transmission shaft and gets rid of stone roller; Said sieve storehouse places the both sides of said gear frame; The said sieve lattice of the inner discharging in sieve storehouse, sieve storehouse upper parallel is symmetrical set two row's charging apertures, and discharging opening is established in the bottom; Power transmission shaft is installed at said gear frame geometric center place, and the inner power transmission shaft both sides of gear frame and two row's charging aperture parallel position symmetries are installed two motors, and two motors are in transmission connection with power transmission shaft respectively, are provided with on the power transmission shaft and get rid of stone roller.Two motors drive same power transmission shaft simultaneously respectively and get rid of stone roller and do the high speed rotary motion, thereby the high-speed plane gyration is done in the sieve storehouse of the square plansifter of said gear frame of transmission and both sides thereof.
Top, said sieve storehouse is provided with in order to compress the hold-down mechanism of sieve lattice.
Said two powers of motor, rotating speed are identical.
The main shaft of said two motors is installed V-belt wheel respectively, the V-belt wheel of being installed on the said power transmission shaft of transmission respectively by V-belt.
The beneficial effect of the utility model is: through Belt Driven by Double Motor; The quick startup of realization equipment; Bi-motor has guaranteed the mass balance of equipment; Effectively reduced to reach the irregular distance of moving about of equipment during of needed time of dynamic equilibrium, reduced the influence that screen effect and sieve nest life-span are brought, can make the flour production line open back entering normal condition rapidly with start.
