Description

A kind of vibrating bin

Technical field

The utility model belongs to the raw charcoal piece of carbon element industry production field, especially relates to a kind of vibrating bin.

Background technology

At present, pre-baked anode carbon blocks, cathode carbon pieces, electrode carbon piece etc., generally adopt vibration moulding both at home and abroadMachine is produced. The core component of vibrating forming machine is shake table, and charcoal piece is produced required vibration force by shakingMoving platform produces. At present, shake table bottom eccentric block structure is generally that fixed eccentric block adds movable eccentric block. AndThe adjusting of vibration force generally realizes by the angle of adjusting two groups of eccentric blocks. On fixed eccentric block and movable eccentric blockThere are several to be the locating hole that fan beam shape distributes, by the combination between different connecting holes on two eccentric blocksAssembling changes the angle between fixed eccentric block and movable eccentric block, thereby reaches the object of adjusting vibration force.And the angle of adjusting fixed eccentric block and movable eccentric block is reorientated peace after movable eccentric block need to being dismantledDress, comparatively wastes time and energy.

Meanwhile, along with the development of carbon element industry, carbon product specification is increasing, for the vibration of its productionForming machine vibration force is also increasing, this just needs by increasing eccentric block quantity, increase eccentric block weight orImproving eccentric block rotating speed realizes. But the restriction of vibrated profile bulk, existing shake table manufacturerGenerally by increasing eccentric block weight and improve eccentric block rotating speed the lifting that realizes vibration force, owing to rotatingIn process, produce very large centrifugal force, eccentric block spring bearing bears very large radial load, belongs to destructiveness and makesWith, eccentric block two end supports bearing life is shorter, and shake table fault rate is higher, is restricting production efficiency always.

On the other hand, for ensureing carbon product product quality, charcoal piece, after vibration moulding finishes, requires vibrationPlatform is in plateau, so that charcoal piece is released, prevents that charcoal piece from damaging. For making shake table at high vibration shapeUnder state, tend to be steady fast, generally adopt the mode of forced brake, need of production starts again next time, prominentRight retarding braking and frequent starting impact larger to eccentric block spring bearing, aggravated the damage of bearing, axleHolding the life-span reduces greatly. Because this kind of shake table structure failure rate is too high, be more and more not suitable with modern productionThe needs of development.

Summary of the invention

For addressing the above problem, the utility model provides a kind of vibrating bin, will organize eccentric block more and concentrate on oneIn casing, rely on gear drive, the one group of eccentric block that produces identical vibration force evenly can be divided into some groups,Reduce spring bearing stressed, and fixed eccentric block and movable eccentric block angle can be realized automatic adjustment. For this reason,The utility model adopts following technical scheme: a kind of vibrating bin, comprising: casing 1, driving shaft 2, power transmission shaft3, moving eccentric gear 4, quiet eccentric gear 5, eccentric block 6 etc.

Described casing 1 is interior arrange two driving shafts 2 and some power transmission shafts 3 (be generally 4,6 or8), be even number configuration, be arranged symmetrically with.

Described driving shaft 2 is arranged on two ends, the interior left and right of casing 1, and it is connected with driving power source motor;

Described power transmission shaft 3, wherein two are arranged between interior two driving shafts 2 of casing 1, all the other two installationsIn casing 1, below two driving shafts 2, power transmission shaft is even number configuration, is arranged symmetrically with the tooth on adjacent diaxonTake turns intermeshing;

Wherein, a moving eccentric gear 4, a quiet bias are all installed on every driving shaft 2 and power transmission shaft 3Gear 5 and an eccentric block 6.

Described moving eccentric gear 4, is arranged on the middle part of driving shaft 2, power transmission shaft 3, with driving shaft 2, passBetween moving axis 3, connect by bearing, relatively rotate between the two.

Described quiet eccentric gear 5, is arranged on driving shaft 2, power transmission shaft 3, moving eccentric gear 4 eccentric blocksA side, and be connected by key between driving shaft 2, power transmission shaft 3, by gear drive, drive eccentric gearRotate, eccentric block thickness is the half of eccentric block thickness on eccentric gear 4.

Described eccentric block 6, is arranged on driving shaft 2, power transmission shaft 3, and moving eccentric gear 4 one sides and are drivenMoving axis 2, turning cylinder 3 connect by key.

Owing to adopting technical scheme as above, the utlity model has following superiority:

Compared with other vibration kind of drive, it is large that it has vibration force, structure flexible configuration, and shaft strength is little,Amplitude is easy to adjust, can realize and not shut down eccentric adjustment piece angle, can realize automation control, can realize zeroAmplitude starts, shuts down, and has advantages of safe and reliable.

Detailed description of the invention

Also by reference to the accompanying drawings the utility model is described in further detail below by embodiment.

Driving shaft 2 is connected with power source, for eccentric block carry-over moment in whole vibrating bin, on every axle, installsQuiet eccentric gear 5, moving eccentric gear 4 and an eccentric block 6, wherein, quiet eccentric gear 5 HesEccentric block 6 adopts key to be connected with axle, between moving eccentric gear 4 and axle, bearing is installed, can phase between the twoTo rotating. On moving eccentric gear 4, eccentric block thickness equals eccentric block thickness on quiet eccentric gear 4 and adds eccentric block 6Thickness, between three, relatively rotating can single shaft eccentric balance, realizes " zero amplitude " start and stop, and bearing is not subject to footpathXiang Li; Under normal operating conditions, identical, the opposite direction of eccentric block deflection angle on adjacent diaxon, thus supportThe horizontal vibration that disappears power, realizes up-down vibration.

Its operating principle is as follows: as shown in Figure 2, two groups of eccentric blocks (quiet eccentric gear 5 is housed on every axleBe connected with axle key with eccentric block 6, be considered as one group of eccentric block). Wherein one group is fixed on axle and is turned with axle by keyMoving, as A, B, C, D, E, F etc., another group can relatively rotate by bearing on axle, and its corner has phaseGear on adjacent axle is controlled, as A1, B1, C1, D1, E1, F1. When shown position, two groups, each axle is inclined to one sideHeart piece position symmetry, therefore, total eccentric moment is zero, now shake table is in zero amplitude state. If changedThe relative rotation of two groups of gears before and after becoming, on each axle, the angle of two groups of eccentric blocks will the variation from 180 ° to 0 °,Eccentric moment on axle will change from zero to maximum so, thus the amplitude that makes shake table also thereupon from zero toMaximum changes.

These are only preferred structure of the present utility model, with other derivative structural change of this structural principle, alsoAt protection domain of the present utility model. For example: single shake table also can be installed multiple vibrating bins, realizes and shakingThe multiplication of power; For another example: according to the size of the arrangement space of shake table and vibration force, vibrating bin can derive againGo out various structures---under level six axle types, upper six axles under two axle types, upper four axles under tetraxon, upper six axles sixAxle type etc.
