Description

The invention relates to a household grain mill with two disc-shaped, coaxial grinding stones with. {, vertical axis, the lower millstone with a | Drive shaft is rotatably connected and the upper f Millstone is attached to a threaded ring, which is used to adjust the grinding gap between the millstones in a at the upper end of the mill housing arranged thread is screwed and on which a funnel for filling | of the ground material is arranged.

Such a flour mill is known. Where the | Threaded ring screwed to adjust the grinding gap in a thread eingearbei- directly into the mill housing \

i

is tet. To clean the grinding chamber of the mill, it is jj required to unscrew the threaded ring, whereby the setting of the grinding gap must be made again. Furthermore, in the known mill, the lower one

Millstone firmly connected to the drive shaft, what that Cleaning the grinding chamber further made more difficult.

The invention as characterized in the claims | is, the task is based on the well-known mill jj in particular to improve so that they can easily f

can be cleaned. \

For cleaning the interior of the mill according to the invention only the Schnei 1verschluß needs to be opened.

The grinding gap determined with the thread adjustment ring and

so that the specified degree of grinding are so when you open the

Grinding chamber not changed.

With the mill according to the invention, all are dry Types of grains grindable, e.g. B. wheat, buckwheat, rye, millet or soybeans, also moist

or oily grist, ζ. B. poppy seeds, then the millstones are preferably replaced by grinding plates.

One embodiment of the invention follows below Mill explained in more detail with reference to the drawing, the single figure of which shows a cross section through the mill.

Thereafter, an electric motor 3 is provided on the lower floor 1 of a lower, barrel-shaped housing section 2, which via a transmission belt 4 with a reduction of z. B. 3: 1 drives a vertical drive shaft 5. The drive shaft 5 is mounted in the bearing 6, the bearing housing of which is flanged to an intermediate base 8. The motor 3 is on the housing 15

Section 2 and attached to the intermediate floor 8.

The grinding chamber 9 is located above the intermediate floor 8 an upper, cylindrical housing section 9 '. In the Grinding chamber 9 are two disc-shaped coaxial with one another ^b

Millstones 10 and 11 arranged. The lower millstone 11

is by a plug connection 12 with the as | Hollow shaft formed drive shaft 5 rotatably connected.

The upper millstone 10 is stationary and on one

Thread adjustment ring 13 attached, e.g. B. glued. It has a coaxial bore 14 for supplying the ground material from a hopper 15 into the grinding gap between the

two millstones 10 and 11. 30th

The setting 13 is for setting the mutual Distance between the two millstones 10 and 11, i.e. the size of the grinding gap is screwed into the internal thread of a quick release ring 16. To a given size To be able to adjust the grinding gap and thus the grinding degree, there is a mark on the thread adjustment ring 13.

ring pin 17 is provided and on top of the Quick release ring 16 at 18 a scale.

The Schnei 1 locking ring 16 is connected to the upper housing section 9 'by a bayonet lock. For this purpose, L-shaped slots 19 are worked into the upper edge of the housing section 9 'and several locking ring 16 is provided on the Schnei 1verschlußring 16. ζ. As a rule, four pins 20, 2Q ^{1 are} provided, which can be inserted into the L-shaped slots 19 of the housing section 9 ¹ and, by turning the SchneiIverschlußring 16, lock the same to the housing section 9 ¹ .

The pin or pins 20 are spherical Handle 21 provided and the or a pin 20 'with star grip is designed as a pressure screw that the unintentional adjustment of the threaded ring 13 opposite the quick release ring 16 prevented.

From the intermediate floor 8 extends from the grinding chamber 9 of the flour outlet 23 dui ", designed as a pipe socket: h the upper housing section 9 ^1. Furthermore, wing strips 24 are arranged on the lower grinding stone 11 on the circumference, which rest on the intermediate floor 8, extending up to the inner wall of the Upper housing section 9 ¹ extend and convey the flour into the outlet 23.

The connector 12 for releasably connecting the lower Millstone 11 with the drive shaft 5 consists of one on flanged to the underside of the lower millstone 11, z. B. glued coaxial pin 25, which engages with a cylindrical fit in the hollow drive shaft 5 and is conical at its end facing away from the grinding stone 11, as well as from a pin 25 radially penetrating pin 26, the

Instead, a multi-start thread can also be used between The drive shaft 5 and the lower grinding stone 11 are provided be or z. B. a keyway connection, an end-face toothing or the like. Also can instead of or in addition to the cylindrical fit, a A taper fit or a multiple fit can be provided,

The upper grinding stone 10 has on its underside a coaxial conical recess 28 into which a coaxial conical projection 29 on the lower grinding stone 11 protrudes. The cone angle β of the recess 28 of the upper grinding stone is preferably 155 to 175 degrees. The cone angle oi of the projection 29 of the lower grinding stone 11 is preferably 5 to 20 degrees greater than that of the recess 28 of the upper grinding stone. Around the recess 28 of the upper grindstone 10 and the projection 29 of the lower grinding stone 11 is of a width of preferably 5 provided on the mutually facing ', {surfaces of the two grinding stones 10 and 11, an annular surface ■ j to 20 mm. Through this design, a high penetration of ground material through the grinding gap and thus a high grinding performance is achieved.
i

The grinding surface of the lower grinding stone 11 is here with go about 1 to 3 mm wide and deep grooves provided that f extend tangentially outward at a distance of 0.5 to 2 cm from a pitch circle. The number .and the The dimensions of the grooves are therefore chosen to be relatively small so that the driving force is not too great

is required when starting the mill.

At the opening of the thread adjustment ring 13 attached hopper 15 is one with a handle 30 provided slide 31 arranged displaceably in radially extending slots 32 in the filling funnel 15.

While in the known mills for emptying the hopper, for example if another type of grain is to be ground, the whole mill has to be turned upside down and, if necessary, the grain must be removed from the grinding gap by enlarging the grinding gap, because otherwise it inhibits restarting of the mill , ¹ ^ is created by the slide 31 the possibility of closing the outlet opening of the hopper 15 and grinding the grinding chamber 9 1eerzumen.

The filling funnel 15, the flour outlet 23, the wing 1 ice 24, the intermediate floor 8, the lower floor 1 and the lower housing section 2 are preferably made of wood, the grinding stones 10 and 11 preferably made of granite and the The remaining parts of the mill are mainly made of metal, the upper housing section 9 'being able to be made of brass.

All materials with which the grain comes into contact are biologically harmless.

The lower barrel-shaped housing section 2 can consist of a be turned full log or consist of barrel pigeons.
