Definitions
- the invention relates to a building material mixer, in particular asphalt or concrete mixers, according to the preamble of claim 1.
- Building material mixers usually consist of a container with at least one driven shaft, are mounted at the perpendicular to the shaft blades bearing mixing arms at intervals to each other.
- the blades are arranged at a distance from the inner wall of the container.
- the mixing arms have an inner part connected to the shaft and an outer part carrying the blades. These two parts are connected to each other by means of an adjustable, screw-connecting device.
- the actual operational connection between the outer parts and the inner parts is fertilized by means of a variety of fferverbin- made locally, when the worn blades must be replaced. In known building material mixers, as they are for.
- the invention is based on the object to remedy this situation and educate the generic mixer without undue constructive effort so that the replacement of the blades can be done with minimal expenditure of time.
- the stated object is solved by the features of claim 1.
- the invention is in any case realized when the proper connection between the inner part and the outer part of a mixing arm in building material mixers by plug, snap, snap and / or bayonet connection is made. This makes it possible to mount new blades without the use of tools.
- the latching connection device on the one hand consists of two pins provided with detent openings, the concurrent with the mixing arm at the end of the inner part at a distance from the diameter of a blade bearing bolts are arranged.
- the latching connection device comprises two central perforated mold parts enclosing the pins, of which one is provided with two spring tabs which can be fitted in latching openings of the pins, as well as a bolt carrying the blade, which makes possible an operational connection between the molded parts. Through this connection, the items are connected via the bolts with the blade to then produce a proper connection of the outer part with the inner part having the pins.
- the assembly of the outer part is factory-made, while the assembly of the building material mixer takes place with new blades on site.
- the distances of the blades to the container inner wall can be adjusted in a simple manner by spacers of different thickness are arranged at the junction between the outer part and the inner part.
- the invention also relates to a method for carrying out the replacement of blades of a building material mixer.
- the protective cover is removed from the sleeve, the connection is released and removed the blade to be replaced.
- the prefabricated locking connection device is fitted with the new blade on the pins.
- FIG. 2 is a perspective view of a mixing arm (inner part) and a side exploded view of an outer part (blade and locking device),
- Fig. 3 is a perspective view of FIG. 2 from the front side and
- Fig. 4 is a perspective view of FIG. 2 from the rear side.
- the figures show a building material mixer with a cylindrical container 1 with a driven central shaft 5, to which blades 12 carrying perpendicular mixing arms 6 are fixed at intervals.
- the axes of the mixing arms with the axis of the shaft 5 may include a different angle.
- the blades 12 are at a distance from the inner wall of the container 1.
- the mixing arms 6 are divided into an inner part 1 1 connected to the shaft 5 and an outer part 13 carrying the blade 12. Both parts can be connected to one another by means of an adjustable connecting device 14.
- the connecting device is generally designed so that the actual operational connection between the two parts, ie the inner part and the outer part, by plugging, snapping and / or twisting is made.
- the advantage of these compounds is that they can be manufactured without tools, which is particularly important when replacing a variety of blades.
- a building material mixer is shown. It consists of a cylindrical container 1, which is closed with a cover 2. Centrally in the container 1, a shaft 5 is mounted by means of bearings 3, 4, are attached to the mixing arms. Only a mixing arm 6 is shown in detail, other 7 - 10 are only hinted at.
- the shaft 5 usually carries a plurality of mixing arms with blades which project from the shaft 5, preferably at right angles.
- the shaft 5 is rotated by a drive 15, for example an electric motor.
- the mixing arm 6 comprises an inner part 1 1 connected to the shaft 5 and an outer part 13 carrying a blade 12, wherein both parts can be detachably connected to one another by means of an adjustable connecting device 14.
- the mixing arm 6 is shown in more detail in Figures 2-4.
- the inner part 1 1 according to FIG. 2 consists of a Mischarmfuß 16 connected to the shaft, for example by means of a screw connection, and a protruding molded part from whose foot-free end face 17 two pins 18, 19 (FIGS. 3 and 4) protrude concurrently with the molded part.
- These pins have latching recesses or latching openings 20, 21 and thus form part of a latching device 22 (FIG. 4).
- a second part of the latching device 22 is formed by two centrally perforated mold parts 23, 24.
- the molded part 23 is provided with two laterally of the perforation 23 a arranged spring tabs 25, 26, which are insertable into the locking recesses 20, 21.
- the molded part 24 is supplemented to a cage, which serves to receive the two pins 18 and 19 and protect against working material.
- a bolt 27 is guided, at one end of a blade 12 is attached via a square piece 28 and which is provided at the other end with a threaded portion 29.
- This threaded portion 29 is provided in the operating state of the outer part 13 (FIG. 1) with a nut 31, which in turn can be covered by a sleeve 30 with protective cover 32.
- the sleeve 30 can be closed to protect the screw against working material with the protective cover 32 arranged at the end. It is essentially a can-lid connection that is simple is solvable.
- the square piece 28 is used in conjunction with folds of the molding 23 to prevent twists of the blade 12.
- the unit consisting of the parts 12, 28, 27, 29, 23, 24, 30, 31, 32 is preassembled when the blade is replaced, the nut 31 of the screw connection being firmly tightened.
- This screw is used only for cohesion of the above-mentioned unit, but not for the preparation of a screw connection between the outer part 13 and the blade 12 and the inner part (arm) 11, as in the conventional building materials mixers in which the actual connection between the arm and the Shovel is made by means of a screw connection, which must be solved when replacing the blade, with a special tool.
- the structure of the mixing arm is thus made such that instead of using a conventional cutting torch or cutters in a very short time the protective cover 32 removed, the nut 31, which holds the unit together, dissolves and can remove the spent blade from the latching connection device 22.
- the new unit can then just as quickly be plugged onto the pins 18, 19, wherein the spring tabs 25, 26 engage in the latching openings 20, 21.
- the distance of the blade edge from the inner wall of the container 1 can be adjusted by means of spacers 23b slipped over the pins 18, 19.
