Description

The invention relates to the construction and road engineering, ί namely, machines intended for the preparation of building concrete and mortars, asphalt concrete mixtures, as well as for molding sands, mixtures for abrasive grinding production, etc.

Closest to the present invention is a vibrating mixer, comprising a housing with a mixing body, the shaft of which is elastically connected to a rotational drive and has a planetary debalance drive with debalances fixed in antiphase [1].

'A disadvantage of the known device is the insufficient intensity of the mixing process.

• The purpose of the invention is to intensify the mixing process due to the multi-frequency processing of the mixture.

. This goal is achieved by the fact that the vibrating mixer, comprising a housing with a mixing body, shaft to

In addition, the drive of the vibromixer includes engines 22.

The vibratory mixer works as follows.

gearing provides rotational movement of the mixing bodies. Droppers 6 and 18 are rigidly fixed on each shaft. Unbalanced satellites are engaged with 30 central wheels 5 and 13 ^ while rotating the shafts roll around around the central wheels. Under the action of inertial forces of unbalanced satellites on the carrier, a significant alternating torque arises, the frequency of which is determined by the ratio of the sizes of the satellites and the central wheels. The blades of the mixing organs make torsional vibrations

independently of each other, i.e. The amplitude characteristic is different from one another.

The components of the stirred mixture are under the influence of either low or high frequency, successively and repeatedly moving from one study zone to another:

The proposed implementation of the device allows Significantly to intensify the process of mixing.

Claims (1)

Claim A vibrating mixer, comprising a housing with a mixing organ, the shaft of which is elastically connected to a rotational drive and has a planetary unbalance drive with unbalances fixed in antiphase, characterized by the fact that, in order to intensify the mixing process due to polyfrequency processing of the mixture, an additional mixing body located parallel to the main one and connected to it by means of an elastic coupling and gearing, the driven wheel of which is free but fixed to a further shaft, wherein the central toothed wheel main and auxiliary drives are the same and satellites - different diameters.
