Description
Affiliated technical field
The utility model belongs to vibrator, particularly a kind of low noise frequency modulation electromagnetism vibrator.
Background technology
At present the vibrator that uses since motor shaft directly be connected by flexible axle with the source body that shakes, the drive source body that shakes rotates, produce collision in the rotation process, make vibrating body produce vibration, the collision between the body because vibrating body, source shake, noise surpasses more than 100 decibels, influence the operate as normal and the rest of surrounding resident, and use three phase electric machine to do power, power consumption is big, the heavy operation inconvenience of equipment.
Summary of the invention
The purpose of this utility model is to overcome above technical deficiency, and the low noise frequency modulation electromagnetism vibrator of a kind of low noise, energy-conservation, portable and effective is provided.
Task of the present utility model is, a kind of source kinetoplast of low noise frequency modulation electromagnetism vibrator is fixed in the vibrating body by stroke shaft, vibrating body and source kinetoplast can relative motions on the stroke direction of principal axis, installation source kinetoplast is an electromagnet in the vibrating body, by the constantly attraction of variation of electromagnet, repulsive force, make vibrating body produce vibration, external power supply inserts variable frequency convertor, frequency modulation makes the vibration frequency of vibrating spear adjustable, with power frequency supply 50Hz, it is adjustable to become 100-300Hz by frequency converter, to adapt to the natural frequency vibration needs of concrete aggregate different-grain diameter, improve vibration efficiency, reached the effect of efficient vibrated concrete.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 shows low noise frequency modulation electromagnetism vibrator structure chart.
Fig. 2 shows low noise frequency modulation electromagnetism vibrator structure chart.
Among the figure, the 1-vibrating body; The 2-source body that shakes; The 3-hole; The 4-electromagnet; The 5-stroke shaft; The 6-capping; 7-power line hole; The 8-power line; The 9-frequency converter; The 10-connecting rod; The 11-plug
The specific embodiment
With reference to accompanying drawing 1,2, a kind of low noise frequency modulation electromagnetism vibrator, has in the vibrating body 1 the installation source body 2 that shakes, the source body 2 that shakes is installed on the stroke shaft 5 at two ends in the vibrating body 1, shake body 2 of source is electromagnet 4, the capping 6 that install the end has wire hole 7 and is provided with power line 8 and connects frequency converters 9, and the source shakes and is provided with electromagnet 4 in body 2 horizontal uniform some holes 3.The source of the low noise frequency modulation electromagnetism vibrator of another embodiment shakes body 2 by some electromagnet 4 horizontal connecting rods 10 connections.Vibrating body 1 and source shake and are provided with moving stroke distances between the body 2.
The source shaken electromagnet 4 are installed in the hole 3 on the body 2 and are installed in the vibrating body 1, the source body 2 that shakes is fixed in the vibrating body 1 by stroke shaft 5, with each electromagnet 4 external 220V power supply, connect variable frequency convertor 9 frequency conversions, frequency change by alternating current, the electromagnetic force at electromagnet 4 two ends constantly changes, adapt to low noise frequency modulation electromagnetism vibrator and produce attraction, repulsive force, make vibrating body 1 produce vibration,, vibrating body 1 is moved along stroke shaft 5 to the source body 2 that shakes if energising moment electromagnet 4 one ends produce suction, but when also not contacting, attraction becomes repulsive force, moves in circles, and reaches the effect that vibration does not produce noise again.
Low noise frequency modulation electromagnetism vibrator amplitude 0.3-1mm, frequency 1-2 ten thousand frequency/min reach one-level dwelling house National Environmental noise criteria below 50 decibels, improve concrete vibration efficient, and jolt ramming is effective.
