The stator part comprises a bayonet locking unit for releasably locking of the milling attachment. A force-transferring coupling unit is formed between a drive axle and a milling stone axle. A support for a milling stone axle bearing is formed at the milling attachment. A milling stone with the bearing and the coupling unit form a component, which is removed and/or inserted from and/or into the milling attachment by detachment of a form-fit and/or force-fit connection. The force-transferring coupling unit is formed as a polygonal outer edge profile and a complementary polygonal inner edge profile.

Description

The invention relates to a multi-part universal grinding and / or screening device, comprising a housing stator part, which accommodates an electromotive drive, a Mahlaufsatz with Mahlsteinanordnung and connectable to the Mahlaufsatz hopper or optionally attachable sieve attachment according to the preamble of patent claim 1.

According to the prior art DE 30 21 368 A1 or DE 43 26 926 C2 Household grain or grain mills are already known.

Such mills have a grinder in which a driven by a motor lower grinding stone and a rotatably mounted upper millstone are received by an adjusting axially adjustable relative to each other.

Furthermore, according to the prior art, a suspension is provided in the mill housing, wherein the upper millstone is fastened to a grinding stone carrier and wherein the motor is fixed to the underside of a grinder base part, on which the upper millstone is supported.

In an alternative prior art embodiment of domestic grain mowing, an adjusting device may be disposed between the housing and an electric motor driving the rotor stone and an upper bearing for the motor shaft of the electric motor, by rotating the motor shaft together with the rotor and the lower end the motor shaft attached lower millstone, d. H. the rotor stone, is displaceable in the vertical direction. By shifting or adjusting the fineness of the ground material can be selected.

In many cases, it is also desirable to subject the ground product obtained for household purposes also a screening process, for which usually household sieves are used.

From the foregoing, it is an object of the invention to provide a further developed multi-part universal grinding and / or screening device, which is constructed on the one module-like, which in particular the area around the driven millstone can be easily cleaned, and on the other hand, the optional operation of a Guaranteed sieve in the sense of a sieve attachment.

The object of the invention is achieved by the grinding and / or screening device according to the feature combination according to claim 1, wherein the dependent claims represent at least expedient refinements and developments.

It is therefore assumed by a multipart universal grinding and / or screening device comprising a housing stator part which receives an electric motor drive. Furthermore, the device includes a Mahlaufsatz with Mahlsteinanordnung, the Mahlsteinanordnung has a rotationally fixed and a driven millstone. Furthermore, a hopper is present, which is connectable to the Mahlaufsatz. Alternatively, a sieve attachment can be coupled to the grinding attachment instead of the feeding funnel.

According to the invention, the housing-stator part with electromotive drive means for releasably locking the Mahlaufsatzes, wherein between the drive shaft and Mahlsteinachse force-transmitting coupling means are formed.

The Mahlaufsatz a receptacle for a Mahlstein axle bearing is formed, wherein the driven millstone with bearing and one of the coupling means forms an assembly. This assembly can be removed from the Mahlaufsatz by loosening a positive and / or non-positive connection and reused.

In this way, it is very easy to exchange the millstone and to clean the remaining Mahlaufsatz or the millstone itself.

The force-transmitting coupling means are formed in one embodiment as Vieleckaußenkant- and complementary polygon inner edge profile.

For connection between the housing stator and the Mahlaufsatz can be made of a known per se bayonet lock or the like solution.

The feeding hopper has a base part, which has a holder for the non-rotatable grinding counter-stone.

In addition, the holder has latching means which engage in an abutment, which are integrated in the Mahlaufsatz. This locking means can, for. B. pin-shaped or bolt-like noses, which can slide into a corresponding hole in the Mahlaufsatz.

The holder for the grinding counterweight is displaceable via the latching means in the longitudinal axis direction of the overall arrangement and spring-biased according to the invention. By a change in distance then the Mahlfeinheitsgrad can be adjusted.

After removing the feeding hopper, the sieve attachment is non-positively connected to the grinding attachment with grinding counterweight, the sieving drive being effected via a friction clutch using the surface of the driven grinding stone. Supplementary force-transmitting means are not necessary in this case.

The invention will be explained below with reference to an embodiment and with the aid of figures.

Hereby show:

1 a perspective view of the device, provided here with a hopper;

2 a detailed view with removed Mahlaufsatz, the top of the driven millstone is visible;

3 a representation of the underside of the Mahlaufsatzes with recognizable Mahlstein-axle bearing and coupling means for releasing and connecting the assembly of grinding stone and Mahlsteinlager based on their seat in the Mahlaufsatz and

4 a detail view of the top of the housing (with drive) with recognizable polygon outer edge profile as a drive axle and bayonet closure means for receiving and locking the in 3 recognizable head bolts at the bottom of the grinding attachment.

As shown 1 The multi-part universal grinding and / or screening device initially comprises a stator part 1 that receives an electric motor or the like drive.

The grinding attachment can be connected to the stator part 2 ,

Above the grinding attachment 2 is the hopper 3 , which at its bottom a base part 4 possesses, which has a holder for the non-rotatable Mahlstein or Mahlgegenstein.

The regrind passes over a chute 5 with corresponding inner opening.

The 2 shows a plan view of the Mahlaufsatz with removed hopper 3 and also removed base part 4 , the part of the task funnel 3 is.

A mission 6 is located inside the grinding attachment 2 , this use 6 an external thread 7 having.

This external thread 7 is complementary to an internal thread in the base part 4 the hopper for the purpose of adjusting the distance between the driven and the rotationally fixed millstone, respectively, for selecting the fineness of the millbase.

Like in the 3 shown, the Mahlaufsatz points 2 a recording 8th for a millstone axle bearing 9 on.

The bearing takes a stub axle 10 on, which has a Innenvielkant to cause a power transmission from the drive axle of the electric motor.

About the illustration "CLOSED" and "OPEN" is indicated as the recording for the Mahlstein axle bearing 9 can be twisted to the intake together with the grinding stone upwards (relative to the direction 2 ) refer to.

It is thus the entire Mahlaufsatz free of mechanically moving elements and can be cleaned dishwasher-safe. Also, the millstone is easily replaceable and thus accessible in this way.

About the head bolts 11 can the entire Mahlaufsatz with the stator 1 get connected.

In this regard are in the 4 two bayonet lock openings are present in which the bolts 11 engage and can be locked by twisting.

Of course, also different connection techniques between the stator 1 and the Mahlaufsatz conceivable without departing from the spirit of the invention.
