Definitions

  • the present invention relates to a mixer device according to the preamble of claim 1, with which mixed material of high viscosity and / or low homogeneity such as moist sand, gravel, grit or also mortar or concrete loosens, mixes and / or takes from one or more extraction points leaves.
  • the mixer device comprises a mixer drum having a base and several mixer arms which point in the direction of the base and can be driven to rotate about a common axis of rotation, each mixer arm having a free end to which a mixer blade unit is attached adjacent to the base of the mixer drum that moves along a respective conveying direction in order to convey the mix in the respective conveying direction.
  • Such a mixer device is basically, for example, essentially from the publications GB 1 018 233 A (which discloses a mixing device according to the preamble of claim 1), DE42 04 687A1 , DE 33 00 299 A1 , GB 620 620 A or GB 1 038 418 A known. Also the EP 1 266 827 B1 describes such a mixer device, but there the mixer blades are rectangular. Such a mixer device is particularly suitable for use in a sandbag filling plant or a concrete mixing plant.
  • the invention is therefore based on the object of meeting this need.
  • the mixer blade unit has a fastening section, by means of which the mixer blade unit (or the mixer blade mentioned) can be fastened to the associated mixer arm, the fastening section having a (preferably inclined) has front surface pointing in the conveying direction, the front surface of the fastening section having two opposite surface sections angled relative to one another transversely to the conveying direction in order to form the mentioned two contour sides of the mixer blade unit.
  • the two relatively angled surface sections of the fastening section form a common ridge which preferably extends in the direction of the mixer arm.
  • the mixer blade unit thus has a gable roof-like shape in the area of its fastening section, thereby forming a kind of clearing blade with which the mix can at least partially be pushed to the side instead of being pushed in front of the mixer blade.
  • the fastening section of the mixer blade unit has a fastening sleeve which receives the free end of the mixer arm, the mentioned two contour sides of the mixer blade unit being formed as an integral part of the fastening sleeve or placed on the fastening sleeve and with the fastening sleeve are firmly connected (e.g. welded).
  • said two surface sections angled relative to one another can be formed by a roof-shaped angle profile which is firmly connected to the fastening sleeve and which forms a ridge that preferably extends in the direction of the mixer arm.
  • the mixer blade unit in question has a contour, i.e. a surface shape and, if necessary, also an outline, which, viewed transversely to the conveying direction, can be assigned to two opposite sides, the distance between which is not approximately constant, but varies at least in sections (in particular along the Conveying direction of the respective mixer blade unit).
  • the conveying or flow resistance of the mixer blade unit can be reduced, so that a lower drive power is required for a predetermined rotational speed or the mixer device can be rotated faster with the same drive power.
  • a smaller electric motor can be used or the material to be mixed can be conveyed more quickly to removal openings formed in the mixer drum with the same drive power, which increases the efficiency of the filling system.
  • the mentioned contour of the mixer blade unit can reduce the effect, which will be explained below, of a sharp increase in the conveying or flow resistance when the mixer blade unit is erected (compared to a preset angle of attack).
  • the mentioned two contour sides of the mixer blade unit can be narrow sides (in particular edges) or broad sides (in particular surfaces).
  • the surfaces of the mentioned two contour sides of the mixer blade unit preferably run obliquely (i.e. at an angle not equal to zero) to the conveying direction, and depending on the embodiment, they can point obliquely in the conveying direction (so that the respective surface acts on the mixed material with at least one directional component) .
  • the distance between the two sides of the contour preferably varies monotonically, i.e. along the conveying direction there is preferably either only an increase in the distance or only a decrease in the distance between the two contour sides.
  • the named contour of the mixer blade unit is preferably designed symmetrically with respect to the conveying direction (in particular symmetrical with respect to a plane that is spanned by the conveying direction on the one hand and an axis running parallel to the axis of rotation through the mixer blade unit on the other hand) so that the mix does not deflect the mixer blade unit to the side or the associated mixer arm causes.
  • the said The contour of the mixer blade unit can also be designed asymmetrically with respect to the conveying direction.
  • contours with varying spacing between the two contour sides can also be provided on the same mixer blade unit, in particular several different such contours.
  • the mentioned conveying direction of the respective (rotating) mixer blade unit generally points within the plane of movement of the respective mixer blade unit in its (current) direction of rotation.
  • the mentioned two contour sides of the mixer blade unit lying opposite one another transversely to the conveying direction can be indirectly connected to one another via a (e.g. straight or curved) front side, or they can be angled directly into one another (e.g. in the form of a wedge).
  • a (e.g. straight or curved) front side or they can be angled directly into one another (e.g. in the form of a wedge).
  • at least two opposite sides of the contour can be identified, which, however, are not necessarily sharply delimited from one another in the case of a rounded, continuous transition.
  • the mentioned two contour sides can converge obliquely, preferably continuously, in order to bring about a low conveying or flow resistance during the rotary movement of the mixer blade unit in question.
  • the mentioned two contour sides can preferably each be designed flat. Alternatively, a curved design of the contour sides is also conceivable.
  • Said contour can be provided on a mixer blade of the mixer blade unit and on a fastening section of the mixer blade unit which is designed for attaching the mixer blade unit to the associated mixer arm.
  • a single common contour of the type mentioned can be provided here, or two contours can be designed separately from one another and of the same type, or separately from one another and differently.
  • the mixer blade unit can have a mixer blade which has two side edges lying opposite one another transversely to the conveying direction, which form the aforementioned two contour sides of the mixer blade unit or the mixer blade and which are angled relative to one another in such a way that the width of the mixer blade with decreasing distance from the free end of the associated mixer blade varies, and preferably decreases.
  • the width of the mixer blade can decrease continuously or in steps with decreasing distance from the free end of the mixer arm.
  • the two side edges are preferably aligned symmetrically to one another with respect to the conveying direction.
  • the mixer blade can have the shape of a trapezoid and preferably that of an isosceles trapezoid. Compared to a rectangular mixer blade, the area of the mixer blade exposed to the material to be mixed is reduced, as a result of which the flow resistance of the mixer blade or the mixer blade unit can be kept small in the desired manner.
  • the mixer blade can have a straight front edge between the two mentioned side edges, which is aligned parallel to the bottom of the mixer drum. In particular, this front edge can form the basis of the aforementioned trapezoidal shape.
  • the mixer blade can have a (preferably inclined) front surface pointing in the conveying direction, wherein the front surface of the mixer blade can have two surface sections angled relative to one another and opposite one another transversely to the conveying direction in order to form the mentioned two contour sides of the mixer blade unit; or wherein the front surface of the mixer blade, viewed transversely to the conveying direction, is convexly curved in order to form the said two contour sides of the mixer blade unit.
  • the two surface sections can form a common ridge, which preferably extends in continuation of the associated mixer arm.
  • the mixer blade thus has a gable roof-like shape, so to speak, and thus functions as a kind of clearing blade. Due to the wedge-shaped shape of the mixer blade, it at least partially displaces the mix to the side, so that the mixer blade has to push less mix in front of it in the conveying direction, which means that less force is required to move the mixer blade unit through the mix.
  • the two surface sections of the front surface of the mixer blade which are angled relative to one another can also only be connected to one another indirectly (instead of being angled to one another).
  • two opposite sides can be identified along the curvature, viewed transversely to the conveying direction, the distance between which varies (and in particular decreases along the conveying direction). This does not rule out that these two contour sides merge continuously into one another when rounded.
  • Two contour sides formed in this way are preferably symmetrical to one another with respect to the conveying direction.
  • the mixer arms themselves can also have a deflection contour, preferably in the form of a wedge cross-section tapering in the conveying direction, in the area of their front face (exactly or obliquely) facing in the conveying direction, so that the mix is at least partially pushed to the side by the mixer arms themselves, instead of it to push in front of the mixer arms.
  • a deflection contour preferably in the form of a wedge cross-section tapering in the conveying direction, in the area of their front face (exactly or obliquely) facing in the conveying direction, so that the mix is at least partially pushed to the side by the mixer arms themselves, instead of it to push in front of the mixer arms.
  • the mixer arms can be designed to be resilient with respect to the conveying direction, wherein they are preferably elastically flexible in themselves.
  • the mixer arms can be attached to a mixer cross that can be driven to rotate, is located in the area of the opening of the mixer drum axially opposite the bottom of the mixer drum and has several legs, each of which carries one or more mixer arms.
  • each mixer blade unit (and in particular the already mentioned mixer blade of the respective mixer blade unit) is inclined by an angle of inclination with respect to the plane of the floor of the mixer drum when the mixer device is in the idle state (ie when the respective mixer blade unit experiences no conveying resistance) this angle of attack can for example be in the range between approx. 20 and 60 °.
  • This also makes it possible to reduce the resistance coefficient of the mixer blade unit, since the mixer blade unit, due to its orientation inclined with respect to the plane of the floor of the mixer drum, only offers resistance to the mix with its surface component pointing in the conveying direction.
  • the mixer drum itself can preferably have a cylindrical, cup-shaped shape with a flat bottom, in which several removal openings are provided for removing the mixed material.
  • the sandbag filling system 10 has a support frame 14 on which a cylindrical mixer drum 13 is mounted, the mixer drum 13 in turn carrying a filling funnel 12 which facilitates the filling of the material to be mixed into the mixer drum 13.
  • a filling funnel 12 which facilitates the filling of the material to be mixed into the mixer drum 13.
  • several removal openings 21 are formed along the circumference of the mixer drum 13, each of which is closed by a rotary valve 19 which can be manually transferred from the closed position to an open position by means of an actuating arm 20.
  • a drive coupling 15 is suspended on the support frame 14 and is connected to a drive shaft 16 in the center of the mixer drum 13 in a driving manner with a vertical drive shaft 16.
  • a mixer cross 17 which has several radially aligned legs 22, to each of which at least one mixer arm 23 is attached, these mixer arms 23 extending from the mixer cross 17 towards the bottom 18 of the mixer drum 13, ie downwards.
  • a mixer blade unit 25 is attached to the free end of each mixer arm 23.
  • a drive shaft such as the cardan shaft of a tractor can be coupled to the drive coupling 15 in order to be able to set the drive shaft 16 of the sandbag filling system 10 and thus the mixer cross 17 together with the mixer arms 23 attached to it in rotation.
  • the sandbag filling system 10 can, however, also have its own drive unit (for example an electric motor).
  • the rotary movement of the mixer arms 23 causes the mixer blade units 25 to move along a respective conveying direction R (cf. Fig. 2 ) emotional.
  • the conveying direction R generally points within the plane of movement of the respective mixer blade unit 25 (which is perpendicular to the axis of the drive shaft 16 and perpendicular to the plane of the paper according to FIG Fig. 1 stands) in the (current) direction of rotation of the respective mixer blade unit 25. This loosens, mixes and / or transports the mix picked up by the mixer drum 13 in the circumferential direction and radially outwards towards the removal openings 21 formed in the bottom 18 of the mixer drum 13.
  • the mixer arms 23 can be, for example, so-called spring tines with an S-shaped configuration, which can deflect elastically against the conveying direction R if they are subjected to an excessively great resistance from the material being mixed.
  • the free ends of the mixer arms 23 and the mixer blade units 25 attached to them have an angle of incidence with respect to the bottom 18 of the mixer drum 13 which is approximately in the range between approximately 20 and 60 °.
  • the mixer arms 23 Due to the elasticity of the mixer arms 23 as well as the orientation of the free ends of the mixer arms 23 at the mentioned angle of attack, the mixer arms 23 can be elastically deflected in the event of large resistances that are applied by the mix until the free ends of the mixer arms 23 including those attached to them Mixer blade units 25 are aligned essentially perpendicular to the bottom 18 of the mixer drum 13. This deflection or retreat of the mixer arms 23 is associated with a corresponding erection of the respective mixer blade unit 25 (increase in the angle of attack). Thus, the mixed material can still be reliably loosened, mixed and / or conveyed even in the case of large resistances which act on the rotating mixer arms 23 from the mixed material.
  • the conveying resistance can increase undesirably sharply (since the surface component of the mixer blade unit 25 pointing in the conveying direction becomes larger).
  • this effect can be reduced by the configuration of one or more of the mixer blade units 25 explained below.
  • the mixer blade unit 25 has a mixer blade 26 which is attached to a fastening section 24 in the form of a fastening sleeve 27, for example by welding.
  • the sleeve 27 is used to fasten the mixer blade unit 25 to the free end of a mixer arm 23.
  • the fastening sleeve 27 is pushed onto the free end of a mixer arm 23 and secured by means of a fastening screw 28, which for this purpose is secured by an in the wall the fastening sleeve 27 formed threaded opening is screwed through.
  • the mixer blade 26 in the embodiment shown has the shape of a trapezoid, which has two side edges 29a, 29b that are inclined (relative to one another and in each case relative to the conveying direction R according to FIG Fig. 2 ) and converge continuously so that the distance created by the two opposite side edges 29a, 29b transversely to the conveying direction R ( Fig. 2 ) is defined, starting from a straight front edge 30 at the free end of the mixer blade 26 in the direction of the mixer arm 23 increases continuously.
  • a power saving of around 30% can be achieved in this way.
  • the two side edges 29a, 29b of the mixer blade 26 opposite one another transversely to the conveying direction R could also be curved (instead of the straight course shown).
  • the mixer blade 26 Due to the trapezoidal configuration of the mixer blade 26 inclined at the mentioned angle of attack and in particular due to the two side edges 29a, 29b which are angled relative to one another, the mixer blade 26 has a contour, the width of which is along the conveying direction R ( Fig. 2 ) varies continuously.
  • the mixer blade 26 has a flat shape in the form of a plate in the embodiment shown, it is also possible to bend the trapezoidal (or with a different contour) mixer blade 26 so that it is transverse to the conveying direction R ( Fig. 2 ) considered has two surface sections which are angled relative to one another and form a common ridge which extends, for example, in continuation of the mixer arm 23 (in the drawings not shown).
  • the mixer blade 26 can also have a gable roof-like, spatial shape, the ridge of the gable roof extending in continuation of the free end of the mixer arm 23.
  • the front surface of the mixer blade 26 pointing in the conveying direction R (obliquely due to the angle of incidence) could be transverse to the conveying direction R ( Fig. 2 ) considered to be convex (also not shown).
  • the mixer blade unit 25 also has a roof-shaped angle profile 31 on the fastening section 24, which is placed in front of the fastening sleeve 27 in the conveying direction R and placed on the fastening sleeve 27, whereby the mutual connection of the legs of this angle profile 31 is in the direction of the Mixer arm 23 extending ridge 32 is formed.
  • the mixer blade unit 25 thus has two surface sections 33a, 33b in the area of the fastening section 24, which are angled relative to one another in order to form the common ridge 32.
  • the mixer blade unit 25 has a gable roof-like shape as a clearing blade in the area of its fastening section 24, which also enables a power saving of about 30% to be achieved.
  • the angle profile 31 thus has a contour that is formed by two opposite sides 29c, 29d in the form of the two angle legs or surface sections 33a, 33b, the distance between the two contour sides 29c, 29d varying (namely continuously along the conveying direction R. decreases).
  • the two contour sides 29c, 29d run towards one another at an angle.
  • a longitudinally cut pipe section e.g. with a partially circular or partially elliptical cross-section
  • Fig. 2 can be removed, two or more mixer arms 23 can be attached to one or more legs 22 of the mixer cross 17.
  • a mixer blade unit 25 with the shape according to the invention can be attached to each of these mixer arms 23; However, it was recognized that it may be sufficient to equip only the radially outer mixer arms 23 with a mixer blade unit 25 with the design according to the invention, since the mixer blade units 25 of the radially inner mixer arms 23 are exposed to only minor forces anyway. In particular, it may be sufficient if all mixer arms 23 are equipped with a trapezoidal mixer blade 26, but only to equip the radially outer mixer blade units 25 in the area of the fastening sections 24 with a roof-shaped angle profile 31 to implement the snow blade function described.
  • the mixer arms 23 can also have such a wedge-shaped shape as the angle profile 31.
  • the flow resistance of the mixer blade 26 is kept low by reducing the area of the mixer blade 26 exposed to the material to be mixed, in particular when the respective mixer blade 26 straightens up due to an increasing conveying resistance.
  • the wedge-shaped design of the mixer blade unit 25 in the area of the fastening sleeve 27 reduces the conveyance or flow resistance of the mixer blade unit 25. Because of the wedge-shaped shape in the area of the fastening sleeve 27, the mixer blade unit 25 at least partially displaces the mixture to the side, so that less force is required to move the mixer blade unit 25 through the mixture, since the mixer blade unit 25 pushes less mixture in front of it.
  • the mixer blade unit 25 Because of the shape of the mixer blade unit 25 according to the invention, less drive force is required to mix the material to be mixed, so that too less powerful drive units such as drive vehicles, engines or power generators can be used. Since less power is required to drive the mixer cross 17, lighter gears can also be used, and the system can also be started from a standstill when it is full.
