Abstract

The utility model relates to a crankshaft helical-ribbon concrete mixing device, which comprises a mixing tank. Two mixing units are arranged in the mixing tank, are respectively connected with a drive unit and respectively comprise a driving helical mixing arm and a driven helical mixing arm, the driving helical mixing arms and the driven helical mixing arms are respectively fixed on a shaft end, the shaft ends are fixed on bearings, the shaft end with the driving helical mixing arms are connected with the output end of the drive motor, and the driving helical mixing arms and the driven helical mixing arms are connected through connectors. Compared with the prior art, the driving helical mixing arms and the driven helical mixing arms substitute two horizontal shafts, therefore, the mixer is prevented from shaft clasping, the efficiency of concrete production is greatly increased, and the defects of concrete caused by concrete grade replacement are also avoided.

Description

A kind of bent axle helical ribbon concrete agitating device

Technical field

The utility model relates to a kind of concrete central mix plant.

Background technology

Concrete central mix plant adopts dual horizontal axle forced concrete mixer usually in the prior art, produce the seize phenomenon easily, not only reduce production efficiency, when changing concrete grade, also cause concrete performance to descend or colour mixture easily, and mixer vibration when work is also bigger.

The utility model content

Main purpose of the present utility model is to overcome the shortcoming that dual horizontal axle forced concrete mixer in the prior art is easy to generate the seize phenomenon, and a kind of bent axle helical ribbon concrete agitating device is provided.

The utility model adopts following technical scheme:

A kind of bent axle helical ribbon concrete agitating device includes an agitator tank, is provided with two agitating units in this agitator tank, and each agitating unit is connected with a drive motors; This agitating unit includes an active helical stir arm and a passive helical stir arm, this active helical stir arm and passive helical stir arm are individually fixed on the spindle nose, this spindle nose is fixed on the bearing, the spindle nose of this active helical stir arm also is connected in the output of this drive motors, and this active helical stir arm and passive helical stir arm interconnect by a connection piece.

Be equipped with stirring vane on described active helical stir arm and the passive helical stir arm.

The hand of spiral of two active helical stir arms of described two agitating units is opposite, and the hand of spiral of two passive helical stir arms of two agitating units is opposite.

By above-mentioned to description of the present utility model as can be known, compared with prior art, a kind of bent axle helical ribbon concrete agitating device of the present utility model has following beneficial effect:

At first, the utility model replaces the dual horizontal axle by active helical stir arm and passive helical stir arm, has avoided the generation of mixer seize phenomenon, improves concrete production efficient greatly, has also avoided because of changing the quality defect of concrete that concrete grade causes;

Secondly, because active helical stir arm and passive helical stir arm are lighter than dual horizontal axle weight, effectively reduced the vibration of mixer.
