(54) CONCRETE MIXER (57) Use: device for the preparation of concrete mix. * Essence: the device contains a cone-shaped with helical lines on the side surface of a concrete mixer, a loading device is often loaded. Each section is made in the form of connected six plates. In the shape of an isosceles triangle. The triangular plate is made with lateral sides, the size of each of which exceeds the size of the base. In each section, the plates are connected in pairs by the lateral sides with the formation of a dihedral angle. 6 ill.

?; · "/ The invention relates to devices for the preparation of concrete mixtures,

The purpose of the invention is improving the quality. wa mixes.

Figure 1 shows a concrete mixer, General view; figure 2 - a view of figure 1; in Fig.3 - view B in Fig.1; figure 4 - housing concrete mixer, General view; Fig. 5 is a perspective view of Fig. 4; on the phybaxonometric projection of the section of the concrete mixer body.

The concrete mixer contains a frame 1 with a manual drive 2 mounted on it, transmitting rotation through gear 3 of the pinion gear 4, in which the housing 5 is mounted rigidly. The track rollers 6 and 7 are fixed to the frame 1, on which the support ring 8 is fixed, which is also rigidly fixed with a housing 5. Wheels 10 are attached to the frame 1 on the axle shafts 9. The frame 1 is provided on one side with two folding crutches 11,12 of constant length, which during movement are straightened in such a way that together with the handle 13, the links 11,12 in the straightened state s betonosme-. the carrier (in Fig. 1 and Fig. 3, the dotted position of the links 11,12 and 13 when moving the concrete mixer).

The casing 5 is made conical with helical lines on the side surface 1 of a step alternating along the length of the casing with three main helical lines with a pitch of Si, which are shown in Fig. 4 by a thickened line 14-17, 18-21, 2225, one helical line of the same direction in increments S2 - 18,

15,23,19,16,24,20,17,25 and one helix '' line in the opposite direction with the Step - 26'17,24,19,15,27. The housing 5 is assembled from sections 28 (Fig. 5 shows three sections whose contours are bounded by a double line), each section (Fig. 6) is made in the form of connected six plates in the shape of an isosceles triangle. The triangular plate is made with side <19> _S.U (and). 1773245 AZ parties, the value of each of which exceeds the value of the grounds. In each section, the plates are connected in pairs by the lateral sides 29 with 30, 31 with 32, 33 with 34 with the formation of dihedral angles a, β, y. 5 In this case, the first pair 29-30 and the second pair 31-32 are made of respectively equal plates, and the bases 35 and 36 of the second pair 31-32 are equal to the lateral side of the plates of the first pair 29-30, and one of the plates 11 33 of the third pair 33- 34 is equal to the plates 29 or 30 of the first pair 29-30. and base 37. another plate 34 of the third pair 33-34 is equal to the side 38 or 39 of the plate 31.

second pair 31-32. 1!

The housing 5 on the side of the crutches 11,12 is provided with a bottom 40, and on the other opposite side, its passage opening 41 is free to load raw materials and unload the finished product. If necessary, manual 2 'drive 2 can be replaced by a mechanical one with installation in its place or parallel to the electric motor.

Benotomy works as follows. . 2

Mixing water and cement through the inlet 41 are fed into the housing 5. The housing 5 is rotated, the direction of which coincides with the direction of the helical lines: the main lines and mixing water 3 and the cement moves into the interior of the housing 5, where, with further rotation of the housing, cement mortar is formed , which is then loaded with aggregates - sand, gravel. After mixing with aggregates 3, the direction of rotation of the housing 5 is reversed and, thanks to the presence of helical lines of the main direction, the concrete mixture moves in the opposite direction towards the inlet 4 (outlet) opening 41 and is discharged from the concrete mixer.

Since the number of helical lines of the main direction is four times the number of helical lines in the opposite direction, the mixture is transported in the direction opposite to the inclination of the axis of the housing 5 and its taper to the limit of 5 ^b ?

During the preparation of concrete mixture, when the casing 5 is rotating, the scythes 11,12,13 form a support frame (emphasis) and provide an inclination of the axis of the casing to 5 ° to the horizontal. When moving the concrete mixer, the crutches 11 and 12 are straightened as shown by the dotted line in FIG. 1 and 2.

Technical and economic benefits from the introduction of a concrete mixer arise due to an increase in the quality of the mixture, as well as simplification of the design and as a result of the rejection of the mechanism for turning the case during unloading, loading and operation of the concrete mixer.

Claims (1)

The formula was invented also for a concrete mixer, containing a sectional case, conical with helical lines on the side surface, each section of which is made in the form of connected plate plates in the shape of an isosceles triangle, and a loading and unloading device, which differs in that, in order to improve quality mixtures, a triangular plate is made with sides, the size of each of which exceeds the size of the base, and in each section of the plates are connected in pairs by the sides to form a double at the same time, the first and second pairs of yen couples.
