Description

 The invention can be used in the construction materials industry and relates to designs of vibratory mixer drives for preparing predominantly hard concrete and similar mixtures.
 A device [1] is known where a vibratory mixer drive is presented, including a planetary gear with paired and floor-mounted central fixed wheels, with which gears are mounted diametrically mounted on the carrier and fastened to the blade shafts, which together with the central wheels contacted with them are made in the form identical ovals and out of phase set in relation to each other. Due to this, with a uniform speed of rotation of the leading carrier, each of the blade shafts rotates unevenly, passing to its mixers (blades), and from them to the mixture being processed, continuous "jerking" effects.
 The disadvantage of this device is that with an uneven speed of rotation of the blade shafts of their rotational-angular vibration, an intense effect on the mixture is transmitted only in the area limited by the peripheral parts of the mixers and with the center at which the axis of the blade shaft resides at any given moment. In this case, the expansion of the vibration zone can only go by increasing the overall dimensions of the mixers, which is not always acceptable, and if possible, it is massive and quite energy-intensive. Another disadvantage of this device is the specificity, namely, that each pre-selected center-to-center distance of the shafts diametrically placed on the carrier requires the installation of gears strictly defined in diameter and oval shape.
As a prototype, a mixer drive [2] was adopted, comprising a housing, an engine, a torque transmission device, a planetary mechanism in the form of a vertically mounted carrier with a fixed sun wheel and satellites, the axes of which are connected via cardan joints to the blade shafts installed inside the housing. In this device, unlike the analogue, with the same overall dimensions of the planetary gear, the blade shafts can be tilted or, on the contrary, brought together, providing for the fixation of their bearings in a certain place of the carrier, thereby increasing the versatility of using this vibroconductor for various according to the capacity of the mixers. However, all this can be done only at the stage of execution of the device, and not during its operation. Thus, the same drawback remains here, the vibration propagation zone is limited by the dimensions of the agitators fastened to the blade shafts. Due to the fact that the agitator in the apparatus are fixed to the vane shafts at an angle not equal to 90, which is ppepogativoy entire mixer instead of its drive, the depth study of the mixture increases, but the range of the vibration propagation in the horizontal plane defined by the radial displacement of the peripheral parts mixers from the axis of rotation of their shafts, this does not increase.
 The purpose of the invention is the intensification of mixing.
 This goal is achieved by the fact that the mixer drive, comprising a housing, an engine, a torque transmission device, a planetary mechanism in the form of a vertically mounted carrier with a fixed sun wheel and satellites, the axes of which are connected by means of cardan joints to the blade shafts installed inside the housing, is equipped with vibration device, drove guides with vertical slots. The vibration device is made in the form of a vertically arranged rod placed on the wheel axis with a loose-fitting sleeve at the lower end, a spring-loaded vibrator of directional vibrations and a base plate. The blade shafts are connected by hinges and spacer levers to the sleeve. Each lever is in contact with the surface of the slot corresponding to the guide, the base plate of the vibrator is connected to the housing by means of power cylinders.
 In FIG. 1 shows a mixer drive, general view; in FIG. 2, section AA in FIG. 1.
 The device comprises a planetary gear transmission in the form of a carrier 1, connected by means of a bevel gear 2 to the engine 3. The carrier 1 contains diametrically mounted satellites 4 with shafts 5 attached to them, connected by cardan joints 6 with blade shafts 8 spring-loaded into the mixer housing 7 equipped with upper bearings 9. Satellites 4 are put into gearing with a fixed (fixed to the housing 7) sun wheel 10, through which a vertical rod 11 is fixed, fixed from the axial movement and a loose sleeve 12 mounted on it, which is pivotally connected to the supports 9 of the blade shafts 8 by means of spacer arms 13 made in the form of sliders in contact with the slot surface of the corresponding guide 14, fastened to the carrier 1. The vertical rod 11 is connected to a vibrator 15 of directional vibrations which, by means of springs 16, is mounted on a base plate 17 supported against the upper surface of the housing 7 by power (pneumatic or hydraulic) cylinders 18.
 The device operates as follows.
 From engine 3, through the bevel gear 2, rotation takes carrier 1, which pulls the satellites 4 and their wool 5 in gear. The gearing of the wheels 4-10 gives the satellite shafts 5 their relative rotation around their axes. Since in this device, unlike the prototype, the supports 9 of the blade shafts 8 are suspended, in order to maintain a certain angular displacement of the shafts 5-8 and their synchronous rotation with the carrier 1, latches are installed in the form of elements 13-14 contacted together, with which and the central sleeve 12 will rotate on a stationary vertical rod 11. In this case, the movement of the blade shafts 8 will be identical to what took place in the prototype, because the angle of displacement of the shafts 5-8 from the engine 3 will not change. In order to intensify the vibration mixing of the mixture components, the impeller shafts 8 are given additional vibrations from the vibrator 15, which through the rod 11 will introduce a central sleeve 12 into the vertically directed vibrations, from which this vibration is transmitted to the impeller shafts 8 through vibrations in the vertical plane of the levers 13, causing them to swing from the pendulum cardan joints 6. The indicated vibration is carried out in the vertical plane of the arrangement of the elements 14-13, and since the latter, due to their joint rotation with the carrier 1, constantly rotate eschayutsya in the horizontal plane considered to vibration vane shafts 8 will "migrate" over the cone, place the generators which occupy themselves paddle shafts. The effectiveness of the pendulum vibration in the form of an increase in its amplitude will take place as the swinging points of the pendulum move away from the suspension axis, i.e., as we approach the mixers (the lower parts of the mixing shafts). This is a significant difference between the pendulum vibration of the blade shafts and their rotationally angular vibration. The proposed device allows the transition from one orbit of the oscillations of the propeller blade shafts 8 to their other orbit, that is, to change the average angular position of the shafts 8 relative to the satellite shafts 5. This is achieved by periodic action of the power cylinders 18 on the base plate 17. As a result, the vertical rod 11 with the central sleeve 12 can either be lowered and thereby the shafts 8 are shifted or, conversely, raised, which will lead to the extension of the shafts 3. The combined inclusion of the vibrator 15 and the power cylinders 18, acting x reciprocating program in advance worked out for each mixture and a specific mixer will give the established intensification of the development of the mixture and a qualitatively increased effect.
