Abstract
The invention discloses a novel double-horizontal axis vibration mixer with vibration and forced stirring functions. The novel double-horizontal axis vibration mixer is characterized in that the novel mixer has functions of the common mixer and has novel functions of three dimensional coordinate discontinuous stirring, self-falling stirring, forced stirring and concrete internal adhesion stress reduction.
Description
Technical field
The invention belongs to a kind of mechanical system, particularly stirred by the discontinuous stirring of three-dimensional coordinate, gravity type, forced action type stirs, reduce the features such as the cohesive force of inside concrete, belong to field of industrial machinery.
Background technology
Mixer produces concrete main frame, the concrete that material stirring uniformly can be conformed to quality requirements by it.Relative to artificial stirring, it have efficiency high, reduce labor intensity and improve the advantage of mixing quality, be requisite equipment during modern good quality concrete is produced.
The mixer of current production has two kinds of forms, and one is the independent stirring unit used; Another is the supporting stirring host of mixer.Although application scenario and the corollary equipment of two kinds of mixers are different, their agitating device is consistent.In order to the concrete stirring requirement of satisfied difference, developed different types of machines, each machine differs from one another on stuctures and properties, can classify from different perspectives, wherein can be divided into gravity type and forced action type two class by stirring theory.
Summary of the invention
This mixer is primarily of compositions such as stirring vane drive unit, vibrator drive unit, mixing drum, stirring vane, vibrator, shaft coupling, belt pulleys.Mixer has mixer drive and oscillation drive two to overlap driving mechanism.Mixer drive power is exported by motor, slows down and synchronous gear transport, by being defeated by shaft after shaft coupling, stirring vane being rotated, stirs material through decelerator.Vibrating device power is exported by motor, is defeated by two vibrating shafts, thus is applied with effect of vibration to material in mixing drum through V belt translation.Under acting in conjunction is stirred in vibration and blade, realize the uniform stirring of material.

Detailed description of the invention
For Vibratory Mixer with Double-horizontal Shafts, the mode applying effect of vibration is not adopt special vibrator, but adopts stirring vibrator exciting mode.Shaft and blade thereof vibrate while stirring, and effect of vibration area is large, and the distance that vibrational energy is propagated is near.Material at edge, teeter chamber is also easy to obtain enough vibrational energies, and the oscillation intensity thus needed is less, and the block bearing life-span of vibrator easily ensures.
When oscillation intensity is less, can considers to increase effect of vibration area, vibrational energy is fully acted on material, the connection between each component of concrete is destroyed, and concrete viscosity significantly declines.Experimental prototype adopts the association schemes of action of forced stirring and effect of vibration.Action of forced stirring makes material be subject to strong convection current, impact and shear action, and material is constantly circulated in mixing drum.Stirring vane and vibration limit, mixing arm limit are stirred simultaneously, and effect of vibration area is large, is conducive to the abundant absorption of material to vibrational energy.As long as action of forced stirring is enough violent and circulate enough fast, when oscillation intensity is less, the micro-property of material will improve greatly, realizes target all homogeneous on concrete both macro and micro.This is also that experimental prototype can choose less oscillation intensity (D<6) and the reason of less vibrational energy.
Test proves, under this exciting mode, concrete quality can be guaranteed.
