Description

[Detailed description of the invention] This invention is related to the improvement of an electric grain preferential device suitable for use with sesame seeds, strained rice paste, etc. This allows accurate centering.

As this kind of grain preferential device, such as a so-called sesame grinder, a rotary mill is disposed in a recess formed at the top of the drive case, and a grain supply device is installed at the open end of the recess. A fixed mortar is attached to the lower end of the container, and this fixed mortar is superimposed on the upper surface of the rotary mortar, and the grains supplied from the container are crushed on both days, and are allowed to fall into the recess. There are some that can be taken out from the outlet formed in the recess.

By the way, although the rotating mill is supported from below in a cantilevered manner on the rotating shaft body side which is connected to a reduction gear or the like,
In order to smoothen the rotation when grains are given preferential treatment,
It is desirable to support this rotary mill from above as well.

For this reason, in the above-mentioned conventional method, as shown in FIG. 4
1 is held in the container 43, a hollow protrusion 44 for a bearing is formed at the center of the fixed mortar 41, and a pivot part 47 formed on the upper surface of the rotary mill 46 is fitted into the hollow part 45 of this protrusion 44. We are jointly supporting each other.

However, in the above configuration, since the fixed position X of the fixed die 41 is located outside the container 43 via the engagement arm 42, the distance R from the hollow protrusion 44 for the bearing to the fixed point X is relatively large. If a slight dimensional error occurs in the arm portion 42, the centers P of the two eyes 41 and 46 will be relatively largely shifted. The teeth 48° and 49 are misaligned and the rotary molar 4
6 is complicated, which interferes with the preferential treatment effect.

Therefore, in this invention, a bearing part is integrally formed in the container, and the bearing part is positioned on the same line as the rotary drive shaft body for driving the rotary eye and engages and pivotally supports the shaft part formed on the upper surface of the rotary mill. By press-fitting and fixing the center hole of the fixed mill, the centers of both eyes are aligned with high precision, and the rotary mill is always rotated smoothly without twisting, thereby effectively exerting the preferential treatment effect. The purpose is to provide preferential treatment equipment.

An embodiment of this invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a cylindrical drive unit case, and this case 1 houses a power source battery 2, a motor 3 driven by the battery 2, and the like.

A driving gear 5 is fixed to the rotating shaft 4 of the motor 3. The rotary drive shaft body 8 is rotated at low speed and high torque via the driven gear 7.

9.10 is a bearing portion of the drive shaft body 8.

If the motor 3 is for high-torque rotation, the speed reduction means can be omitted.

Reference numeral 11 denotes a recess forming a grain preferential space formed at the upper end of the drive unit case 1, and the tip of the rotary drive shaft 8 passing through the bottom wall 12 of the recess 11 is inserted into the recess 11. 13
protrudes, and a cup-shaped container 15 for supplying grains is removably attached to the open end 14 of this recess 11.

Reference numeral 16 denotes a circular rotary mortar made of synthetic resin or the like disposed within the recess 11, and 17 a circular fixed molar made of synthetic resin or the like which is superimposed on the upper surface of this rotary mortar 16. It has 19.

Reference numeral 20 denotes a rotary mill holder fixed to the distal end portion 13 of the rotary drive shaft body 8, and the rotary mill 16 is connected and held to the holder 20 via a locking leg 21.21 vertically provided on the lower surface of the rotary mill holder. The holder 2 is rotated by the rotational drive shaft 8.
It is designed to rotate with 0.

Furthermore, the rotary mill 16 is elastically supported by a spring member 22 interposed between it and the holder 20 so as to be movable up and down.

The fixed mortar 17 has an input port 2 corresponding to the grain supply port 24 formed at the center of the inclined bottom wall portion 23 of the container 15.
5 is formed, and the grains falling from the supply port 24 are fed between the preferential teeth 18 and 19 of the two days 16 and 17.

26 is a hollow protrusion for a bearing located on the same axis P as the rotational drive shaft 8 and integrally formed with the container 15;
A pivot portion 28 formed on the upper surface of the rotary die 16 is fitted into the hollow portion 27 of the protrusion 26 and is pivotally supported, and the protrusion is fitted into a through hole 29 formed at the center of the fixed die 17. 26
is press-fitted and fixed.

30 is a cap of the container 15, 31 is a grain powder shaker opening after being treated, and 32 is a grain powder feeding blade after being treated.

In the above configuration, the rotary mill 16 is
is rotated together with the holder 20, and grains such as sesame are passed from the container 15 side through the inlet 25 to the preferential teeth 18.
, 19, the sesame seeds 81') are crushed by the gentle crushing action of these teeth 18, 19.

The crushed sesame powder falls into the recess 11, and
It is fed by the feed blade 32 and swung out from the swung opening 31.

Here, the rotary mill 16 is supported by the hollow protrusion 26 of the container 15 with the pivot portion 28 on the upper surface thereof, so that it is stable in a supported state with the upper and lower surfaces supported, and in particular, the hollow protrusion 2
Since the fixed mill 17 is press-fitted and fixed to 7, the axis P and the fixed point X
The distance r becomes relatively small, and even if there is a dimensional error in the fixed die 17, the centers of both days 16 and 17 can be aligned approximately on the axis P of the rotary drive body 13. This effectively prevents twisting.

Note that even if the rotary mill 16 is configured to be directly connected to the rotary drive shaft body 13 or the rotating shaft 4 of the motor 3 without using the holder 20, the same effects as in the above embodiment can be achieved.

As described above, this invention forms a hollow protrusion integrally with the container, which is located on the same axis as the rotary drive shaft for driving the rotary eye, and which engages and pivots the pivot formed on the upper surface of the rotary mill. However, by press-fitting and fixing the stationary mortar into this protrusion, it is possible to provide an electric grain crusher that can achieve high precision center alignment on both days and effectively exhibit preferential effects.
