Definitions
- the present invention relates to a process for preparing a mixture, in particular for making concrete, mortar, grout or the like intended for masonry.
- the present invention also relates to an apparatus allowing the mixing of several ingredients such as sand, cement, water for example, for the implementation of the method.
- the mixing of such ingredients is traditionally carried out using a concrete mixer.
- the tank generally has a circular outline around an inclined axis of rotation. During the rotation of the tank, the inner peripheral surface of the tank, fitted with drive projections, causes upwards fractions of the mixture which eventually fall back into the mass of ingredients occupying the lower zone of the interior volume of the tank. . This repetitive succession of workouts and fallout of part of the mass produces the desired mixing.
- the tank has an opening directed obliquely upwards making it possible to add this or that ingredient during mixing, for example water.
- the mixture is made, it is emptied into a wheelbarrow then it is transferred from it into a trough where the mason takes the mixture using a trowel.
- An object of the present invention is to provide a mixing method and apparatus making it possible to reduce the cost and / or the weight and / or the bulk of the equipment, and / or to simplify its use and cleaning, or in any case to make an improvement on one of the aforementioned points.
- the method for preparing a mixture, in particular for making concrete or the like, in which the ingredients of the mixture are placed in a tank and to knead the mixture the tank is rotated around 'an oblique axis is characterized in that one uses a tank having a polygonal contour around a bottom transverse to the axis of rotation.
- the polygonal contour of the tank is sufficient for fractions to be driven in rotation with the tank to a sufficient height so that they then fall back in an effective manner for the kneading action. in the mass occupying the bottom of the interior volume of the tank.
- the tank can be considerably simplified, it no longer needs internal projections.
- the tank is therefore less expensive, lighter, easier to clean and makes it much easier to draw directly from the prepared mixture, as well as to use - 3 - complete the mixing without significant quantities of mixture remaining trapped in the complex internal shapes of a conventional tank provided with internal blades.
- a removable trough suitable for transporting the mixture to a place of use of the mixture after kneading is used as a tank, for fear of drawing the mixture there with a trowel.
- the gauge can be an article of commerce, therefore at a very low price.
- the user can have two troughs: one is used to make a new quantity of mixture while the other is at the place of use of a quantity previously prepared. Once this quantity has been used up, the user returns to the mixing apparatus with the empty trough and places it on the apparatus after having extracted the full trough which he in turn takes to the place of use.
- a cover provided with a central opening on the trough. Thanks to the oblique axis of rotation at an angle which can be approximately 60 ° with respect to the vertical, it is possible to ensure that the normal filling level of the tank is compatible with an absence of overflow through the orifice central during rotation of the tank.
- the orifice allows an inspection of the mixture during the rotation of the tank and, if necessary, a modification of the composition of the mixture by adding an additional quantity of such or such ingredient.
- the orientation means comprise two support planes of the chassis on the ground, defined by a support zone substantially parallel to the bottom of the trough and an oblique support zone relative to the bottom of the trough It is thus sufficient to switch the entire apparatus to pass from one to the other of the orientations. This considerably reduces the complexity of the device, therefore its weight, its price and its risk of failure.
- FIG. 1 is an elevational view of a kneading apparatus according to the invention, in substantially horizontal orientation, with axial section of the tank and the support
- - Figure 2 is an exploded view of the apparatus of Figure 1, in perspective;
- Figure 3 is a view similar to Figure 1 when the device is in its inclined kneading orientation
- Figure 4 is a view similar to Figure 1, but when the device is in the storage configuration, the upper half view and the lower half view corresponding to two different situations
- the apparatus comprises a tubular frame 1 (FIG. 1) having, seen in profile, a general shape of a quadrilateral, more particularly of a rectangular trapezium.
- the frame 1 defines along the large base of the trapezoid a base 2 intended to indirectly support a mason's trough.
- the chassis 1 further defines along the small base of the trapezoid and the oil side of the crapeze two support zones 7 and 11 together forming a dihedral and connected to each other by a 120 ° elbow, designated by the reference 9
- the bearing area 7 is substantially parallel to the base 2 and therefore to the bottom 6 of the trough 4
- the second support zone 11 is oblique with respect to the axis 3 and with respect to the bottom 6 of the trough.
- the latter can be selectively positioned in a substantially horizontal orientation. shown in Figure 1 for filling and handling operations, the support area 7 being placed on the ground 8, or in an inclined kneading orientation shown in Figure 3, where the oblique support area 11 rests on its lower support plane on the substantially horizontal ground 8
- the kneading takes place by rotation of the trough 4 around the axis 3 inclined by about 60 ° relative to the vertical end of the dihedral associated with the support zone 7, the latter is connected to the base 2 by two successive 90 ° elbows designated by the reference 12, separated, along the fourth side of the trapezium, by a third support zone 13 ortnogonal to the parallel support zone the 7 and at the base 2
- the third support zone 13 allows the device to rest in
- the chassis i comprises as main component a tube 14 curved into a U at a free end 16 of the support zone 11, constituting the other end of the dihedral
- This end 16 forms a handle for transport ⁇ e 1appareA in the upright position, or for its attachment to a wall bracket 15 as illustrated in the upper part of Figure 4 as a variant that the support by the support area 13 on the ground 8
- the tube 14 forms two symmetrical longitudinal members each extending along the oblique support area 11, then along the oblique support area 7 and the third support area 13, then finally parallel to one another along the base 2, where the two longitudinal members terminate in a respective free end 17.
- the curved end 16 is located substantially in the plane of the base 2, at a certain distance beyond the two free ends 17.
- the two longitudinal members are also parallel 1 'to one another but more spaced from one another than in the base 2 , and they are joined there by two welded tubular crosspieces 18.
- the two longitudinal members converge towards each other from bottom to top, towards the curved end 16 and towards the base 2 respectively.
- the apparatus further comprises a box 19 comprising two parallel and opposite lateral barrels 21 by which it is fitted on the two longitudinal members in their zone making up the base 2.
- the box 19 also comprises a central housing 22 in which is installed according to the axis of rotation 3, a self-lubricating bronze plain bearing 23 open on the side opposite to the support zone 7.
- the box 19 is immobilized along the emoase 2 by two pins 24. Each pin 24 passes through transverse holes correspondents formed in a respective one of the barrels 21 and in the associated spar of the base 2.
- the apparatus further comprises a support 26, made for example of sheet metal, comprising a substantially flat and rectangular base plate 27, the underside of which, turned in service towards the box 19, carries a pin 28 intended to be fitted in the bearing 23.
- the pin 28 is rigidly connected to the plate 27 by means of a cylindrical drum 29 which is coaxial with the axis 3 when the pin 28 is in the bearing 23.
- the support 26, whose plate 27 is intended to support the bottom 6 of the trough 4 further comprises four lateral wings 31 each starting from one of the sides of the plate 27 to position the trough 4 on the plate 27 so that the geometric center of the trough 4 roughly comcides with the axis of rotation 3.
- each external lateral face 32 of the trough 4 rests against a respective one of the wings 31
- the trough 4 can typically be a commercial trough, of generally rectangular shape, flared in the trunk of a pyramid from its bottom 6 to an open edge 33 equipped with a peripheral rim 34, curved towards the outside.
- the apparatus further comprises a cover 36 with four side walls 38 flaring in the shape of a pyramid trunk from a generally rectangular upper wall 37 to a peripheral edge 39 equipped with a lip 41 directed obliquely towards the upward and outwardly
- the outer face of the lip 41 is capable of nesting and of being centered in the open edge 33 of the trough 4.
- the lip 41 forms with the side walls 38 of the cover 36 a peripheral groove 42
- Two opposite wings 31 of the support 26 each carry a quick coupler 43 comprising a clamping spout 44 engaging with the cover 36 in the peripheral groove 42 to urge the cover 36 towards the support 26 by pressing the bottom 6 of the trough 4 against the plate 27 of the support 26.
- the cover 36 has through its upper wall 37 a central opening 46 centered on the axis 3, provided with a raised edge 47.
- the level of the mass 48 of the ingredients to be kneaded is located below the lowest part of the peripheral edge of the opening 46, so as to avoid any overflow. This results from an appropriate choice of dimensions and in particular or diameter of the opening 46
- the opening 46 makes it possible to visually inspect the kneading, and in particular the consistency of the mixture obtained, and supplement the mixture if necessary by adding an additional quantity of such or such of its ingredients.
- the support 26 is placed in the trough 4 (FIG. 4), the cover 36 is replaced on the trough 4 and then the orifice 46 is closed with a bucket 49 whose bottom comes to rest on the base plate 27 of the support 26.
- a bucket 49 whose bottom comes to rest on the base plate 27 of the support 26.
- the bucket the outside diameter of which corresponds to that of the orifice 46, closes the latter and prevents the tools from escaping from the trough.
- the bucket 49 is preferably a dosing bucket facilitating the choice of appropriate amounts of each ingredient in the mixture.
- the apparatus then takes a particularly compact storage configuration, suitable for storage in the upright position on the ground 8 as illustrated in the lower half of FIG. 4 or suspended on the hook 15 as shown in the upper part of FIG. 4.
- the bucket 49 serves as a wedge supported under the base 2, more precisely under the bearing box 19, and thus immobilizes the support 26 against the bottom of the trough 4 and the bottom of the trough 4 against the bearing area 7 of the chassis.
- the rotation of the trough 4 around the axis 3 can be carried out for example by hand.
- a frame 52 of the drive means 51 carries two parallel barrels 53
- FIG. 2 for the fitting of the means 51 on the two side members of the base 2 in the area between the box 19 and the elbow 12 of transition with the third support area 13.
- the frame 52 contains a speed reduction gear 55 (not shown any more) having an output shaft equipped a pulley 54 which is in the same plane as the cylindrical drum 29 of the support 26 when the pin 28 is in place in the bearing 23.
- a drive belt 56 couples the pulley 54 with the drum 29 which then serves as take-up pulley. To install the belt, simply place it around the drum 29 before engaging the pin 28 in the bearing 23 and then - 10 - pass the belt 56 around the pulley 54.
- the frame 52 further comprises a frame formed by a plate 5 7 supporting a collar 58 for the removable fixing of a portable drill 59 in a position such as the spindle 61 of the drill can be coupled by clamping on the input shaft 62 of the reduction gear 55.
- the reduction gear 55 is of a type where the output shaft is at 90 ° relative to the input shaft 62.
- a toggle device 64 controlled by a manual lever 66 acts on the box 19 and on the frame 52 of the drive means 51 to selectively separate the drive means 51 from the support 26 along the base 2 and thus tension the belt 56, or on the contrary bring the frame 52 of the support 26 to relax the belt 56 and allow its disassembly, and also to bring the drive means 51 and in particular the plate 57 into a retracted position ( Figure 4) between the two rails of the chassis.
- the invention is not limited to the examples described and shown.
- the motorization method described has the advantage of being able to be marketed as an option that can easily be adapted to basic equipment with manual rotation.
- the realization in the form of a simple reducer having as input edge a PTO strap adaptable to a drill allows a particularly economical embodiment.
- the frame can take a shape other than that described, its configuration can be in a non-rectangular trapezoid or even in a non-trapezoidal polygon, and it can be produced otherwise than in tubes. To meet the formal requirement of descriptive support, it is specified that:
- the electric drill 59 can be replaced by a similar means
- the toggle joint 64 and manual lever device 66 is a means of spacing between the support 26 and the drive means 51; the raised edge 47 is a preferred arrangement of the orifice 46; and
- the quick couplers 43 are means for fixing the cover 36 to the trough 4 by urging the cover 36 relative to the support 26.
