DEPTH CONNECTING MACHINE OF CONCRETE MIXTURES at author. St. 923825, characterized in that, in order to increase the efficiency of compaction, the working body is made with a central longitudinal cavity, and the causative agent of x1blebany is in the form of a flexible sleeve placed in the last flexible shaft and runners in contact with the inner surface of the working body.

Description

This invention relates to the compaction of concrete mixes.

According to the main auth. No. 923825, a well-known depth vibrator is known, containing a working member curved along a helical line with a cross-shaped cross-section, on the upper end of which a bracket with an exciter of directional oscillations 1 is fixed,

However, the known vibrating compaction is characterized by a sufficient efficiency of compacting the concrete mix.

The purpose of the invention is to increase the efficiency of compaction.

This goal is achieved by the fact that in the deep vibratory compactor of concrete mixes containing a working body curved along a helical line with a cross-shaped cross section at the upper end of which is fixed a bracket with a causative agent of directed oscillations, the working organ is made with a central longitudinal cavity, and the causative agent of oscillations is placed in the last flexible shaft with movable in the longitudinal direction of the split sleeves and runners in contact with the inner surface of the working body.

In Fig.1 schematically shows a deep vibrator, General view; figure 2 is the same cross section; on fig.Z - paSpes aa on figure 2

The deep vibratory compactor of concrete mixes contains a tsinindric working body 1 and a flange 2 on which is fixed a bracket 3 with a drive 4, for example, an oscillation exciter motor made in the form of a flexible shaft 5 placed in a hollow housing with split sleeves b and runners 7

in contact with the inner surface of the body of the working body.

The device works as follows.

Using a crane or manually (for a small compactor), the tool is inserted into the concrete cavity filled with concrete mixture by the working part. The electric motor 4 vibrates 5. When the fast rotation vibrates 5, the sliders 7 due to the gap between them and the working body 1 roll around on the inner surface of the body and press unbalanced centrifugal force to the sliders. When this occurs, the effect of high-frequency circular oscillations due to the planetary run-in of the runners.

During operation of the vibrating compactor, it is possible to provide automatic deepening and extraction of the working organ from the concrete mixture by reversing the rotation of the vibrating motor. This results in the effect of engaging or pushing out the working body due to the axial direction of the concrete mixture on the helical blades.

The vibratory compactor is turned off after the compaction of the concrete mix is completed and the working part of the tool leaves it.

The design of the vibra has no expensive parts (rolling bearings, elastic couplings, etc.), does not need lubrication and is easily replaced during repair by disconnecting the flange and removing the vibrated from the housing.

The use of the invention improves the compaction efficiency of the concrete mix.
