Description
Technical field
The utility model belongs to excitational equipment technical field, is related to a kind of polygon self-balancing of concrete batch plant
Formula vibrator.
Background technology
Vibratory Mixing is compared with traditional forced mixer, because its stirring efficiency is higher, mixing quality is good, should in engineering
It is more and more extensive in.Vibratory concrete stirring is the high-frequency vibration and agitating device collective effect generated by vibrator to object
Material is stirred, to improve mixing quality and efficiency.The vibrator of existing oscillating mixer generates vibration, axis using eccentric center principle
The sealing effect at end is bad, and shaft strength is not in good state；It easily generates heat under high-frequency vibration state, bearing life is not high；Meanwhile
Stress is complicated during stirring, and vibrator stress is not easy to balance, and vibrational energy cannot all act on manipulating object and easily generate and make an uproar
Sound pollution so that construction condition is severe, does not meet the current environmentally protective requirement in China or even can influence construction personnel's body
Body health.
Utility model content
The purpose of this utility model is to provide a kind of polygon self-balancing type vibrator of concrete batch plant, with
It solves the above problems.
To achieve the above object, the utility model uses following technical scheme：
The polygon self-balancing type vibrator of a kind of concrete batch plant, including power plant, polygon vibrating shaft；
The both ends or one end of polygon vibrating shaft are provided with power plant, and power plant drives the rotation of polygon vibrating shaft；Polygon shakes
Moving axis has the axis of the polygon of N number of smooth bumps for cross section, and N is more than or equal to 1；Axial direction of the smooth bumps along polygon vibrating shaft
Screw arrangement.
Further, the both ends or one end of polygon vibrating shaft are provided with connecting shaft, and bearing, power are arranged in connecting shaft
The output terminal of device is with connecting axis connection.
Further, organic frame is set on bearing.
Further, the helix angle of polygon vibrating shaft is 0 °~90 °；Polygon vibrating shaft is solid shafting or hollow
Axis, and the barycenter of polygon vibrating shaft rotates center coincidence.
Further, material movement direction and state change with the helix angle of polygon vibrating shaft and are changed.
Further, the amplitude of vibrator and height of projection positive correlation.
Further, excited frequency f=N × vibrator rotating speed/60 of vibrator.
Compared with prior art, the utility model has following technique effect：
The polygon vibrating shaft of the vibrator of the utility model is the polygon with N number of smooth bumps, polygon during work
Shape vibrating shaft often rotates a circle, and N number of protrusion collides with material, and material can be by the axis generated from raised spiral at this time
It is acted on to power and radial load, in chatter state.Material is stirred under high frequency chatter state, the internal friction between particle and
Cohesive strength reduces, and under the stirring action of agitating device, material is more easy to reach both macro and micro uniform.In addition, vibrator shakes
It is dynamic that the cement little particle of agglomerate is promoted to disperse to become smaller rapidly, increase the contact area with water, accelerate hydration reaction, further increase
Strong interface binding intensity between aggregate and Behavior of Hardened Cement Paste.The collective effect of vibration and stirring improves mixing quality and efficiency, drops
Low specific energy consumption.Different from eccentric vibrating principle, spiral vibrator is generated by the protrusion of spiral vibrating shaft with material collision
Vibration, vibrator barycenter overlaps always with rotation center during work, and vibrational energy is only transmitted to material without being transmitted to rack, overcomes
The deficiency of conventional vibration blender.
The utility model is related to spiral vibrator compared with existing blender vibrator, can be by changing spiral liter
Angle changes material movement direction and state so as to fulfill different mixing effects, while again can be by improving the number of polygon
Exciting amplitude can be changed to improve excited frequency or change height of projection, to realize that high-frequency vibration provides new method；Structure letter
It is single, it is easy for installation；In addition, the barycenter of the type vibrator is overlapped with rotation center, bearing support is not produced in high speed rotation
Raw exciting force, shaft strength state is preferable, can effectively reduce noise pollution, extends bearing life.

Specific embodiment
The utility model is further illustrated below in conjunction with attached drawing：
Please refer to Fig.1-Fig. 3, the polygon self-balancing type vibrator of a kind of concrete batch plant, including power plant
1st, polygon vibrating shaft 2；The both ends or one end of polygon vibrating shaft 2 are provided with power plant 1, and power plant 1 drives polygon
Vibrating shaft 2 rotates；Polygon vibrating shaft 2 has the axis of the polygon of N number of smooth bumps for cross section, and N is more than or equal to 1；It is smooth convex
It rises along the axial screw of polygon vibrating shaft 2 and arranges.
The both ends or one end of polygon vibrating shaft 2 are provided with connecting shaft, and bearing 3 is arranged in connecting shaft, power plant 1
Output terminal is with connecting axis connection.
Organic frame 4 is set on bearing 3.
The helix angle of polygon vibrating shaft 2 is 0 °~90 °；Polygon vibrating shaft 2 is solid shafting or hollow shaft, and polygon
The barycenter of shape vibrating shaft 2 rotates center coincidence.
Material movement direction and state change with the helix angle of polygon vibrating shaft 2 and are changed.
The amplitude of vibrator and height of projection positive correlation.A as shown in Figure 3 is the amplitude of vibrator.
Excited frequency f=N × vibrator rotating speed/60 of vibrator.The excited frequency of vibrator and raised quantity N are linearly just
Correlation, excited frequency can be improved by increasing N or rotating speed；
Assuming that sometime the mixture of a certain position collides with spiral vibrator, the material is in addition to by spiral shell at this time
Outside the effect for revolving the radial load of vibrator, it can also be acted on by axial force, since vibrator rotary speed is far above mixing speed,
This process elapsed-time standards is extremely short, and vibrator surface is more smooth, thus in the process at this mixture athletic meeting along
The direction movement of resultant force, movement velocity is higher, and displacement is little, in chatter state, reaches dither effect；With reference to agitating device
Macroscopic view stirring, the two collective effect realize Vibratory Mixing, so as to effectively improve mixing quality, shorten mixing time.
