Abstract

The invention relates to devices for the preparation of concrete mixtures and allows to intensify the mixing process. The vibration mixer contains two horizontal bladed shafts 2 connected to a gear synchronizer 3 and installed in a trough-shaped case 1, which is suspended on a fixed frame 6 on shafts 8. One shaft 8 is connected to a torsional oscillator of a planetary torsional oscillator relative to the frame 6 which is spring-loaded relative to the frame 6 , kinematically connected with the engine 7. The vibration mixer is equipped with an additional planetary gear with internal gearing located at one end of the blade shaft 2. 4 Il.

The invention relates to industrial construction materials and can be used for the preparation of predominantly rigid concrete and similar mixtures.

The purpose of the invention is to intensify the mixing process.

Figure 1 shows the vibrating mixer, a general view; figure 2 is a view of And figure 1; On fig.Z - section bb in figure 1; rta figure 4 - section bb In Fig, 1. ; The vibratory mixer contains a trough-shaped housing 1 with two horizontal propeller shafts 2 placed in it, kinematically closed and toothed synchronizer 3. On one of the propeller shafts 2, the satellite 4 is fixed, connected to a fixed central wheel 5, fastening on the frame 6, bearing engine fenb 7 and bearings with them installed. end shafts 8. The latter are placed on the frame 6 along the longitudinal fairy symmetry of the housing 1. A spring-loaded driven carrier 9 of a planetary torsional vibration puller connected to the engine shaft 7 is connected to one of the end shafts 8. The sun gear 10 is injected into gear with satellites 11, which are counter-phase unbalanced with loads - unbalances 12.

The vibratory mixer works as follows.

From the shaft of the engine 7, the rotation is received by the sun gear 10, which causes the satellites 11 to rotate.

Due to the out of phase imbalance of these satellites, a alternating dynamic torque — torsional vibrations — is created on the carrier 9. The magnitude of these oscillations is limited by the stiffness of the truncated elements 13. The torsional vibrations of the housing 1 relative to the axes of the end shafts 8 cause periodic partial running-in of the satellite 4 on the central wheel with internal teeth 5, which, in turn, are transmitted to the blade shaft 2.
