Description

[Detailed description of the invention] This invention relates to the improvement of an electric grain preferential device used for sesame grinding and sesame grinding.

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. There are some that can be taken out from the exit formed in the place.

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 device, as shown in FIG. A mortar 41 is held in the container 43, a hollow projection 44 for bearing is formed in the center of the fixed mortar 41, and a pivot portion 47 formed on the upper surface of the rotary mortar 46 is formed in the hollow portion 45 of this projection 44. Fitted and pivoted.

However, in the above configuration, since the fixed position X of the fixed mortar 41 is located outside the container 43 via the engaging arm portion 42,
If the distance R from the bearing hollow protrusion 44 to the fixing point X is relatively large and a slight dimensional error occurs in the arm 42,
The centers P of both days 41 and 46 will be relatively shifted significantly, and as a result, the respective preferential teeth 48 and 49 of both days 41 and 46, which should properly face each other during the preferential treatment, will be shifted from each other, causing the rotary molar 46 to become distorted. , which interferes with the preferential treatment effect.

In order to solve this problem, a bearing part is integrally formed in the container, which is located coaxially with the rotary drive shaft body for driving the rotary eye, and which fits and pivots the shaft part formed on the upper surface of the rotary mill. By press-fitting and fixing the center hole of the fixed mill into the bearing part, the centers of both sides can be aligned with high precision, and the rotary mill can be rotated smoothly at all times without twisting. .

However, in this case, since the fixed point of the fixed die is located at the center of the container, there may be a slight difference between the outer circumferential surface of the fixed die and the inner circumferential surface of the container due to dimensional errors of the container or the fixed die. A gap G (Fig. 2) may be formed, and in that case, the grain powder scattered after the treatment continues to enter the upper surface of the fixed mill through the gap G, which is unhygienic and especially Grain flour with a high fat content, such as sesame flour, suffers from an unpleasant odor due to the rotting fat content.

Therefore, this invention has an annular tongue protruding from either the outer circumferential surface of the fixed mortar fixed to the center of the container or the inner circumferential surface of the container to elastically abut against the opposing surface. This eliminates the above drawbacks.

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, and the motor 3 includes the driving gear 5, a reduction gear 6 meshed with the driving gear 5, and a driven gear meshed with the reduction gear 6. 7, the rotary drive shaft body 8 is rotated at low speed and high torque.

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 crushing teeth 18 and 19 of the two days 16 and 17.

Reference numeral 26 denotes a hollow protrusion for a bearing, which is located on the same axis P (FIG. 2) as the rotary drive shaft body 8 and is integrally formed with the container 15. The above rotary mill 1
A pivot portion 28 formed on the upper surface of the fixed die 17 is fitted and pivotally supported, and the protrusion 26 is press-fitted into a through hole 29 formed at the center of the fixed die 17.

30 is an annular tongue protruding from the outer circumferential surface 17H of the fixed die 17, as clearly shown in FIG. is elastically abutted against.

In this embodiment, the tongue piece 30 is formed of a thin blade-shaped piece integrally formed on the outer circumferential surface 17a of the fixed die 17.

In FIG. 1, 31 is a cap that removably closes the opening of the container 15, 32 is a sending blade protruding from the outer peripheral surface of the rotary mill holder 20, and 33 is a cap provided in a part of the recess 11. This is the outlet for the formed grain powder.

In the above configuration, the rotary mill 16 is driven by the rotary drive shaft body 8.
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, these teeth 18.19 1)
Due to the crushing action, the sesame seeds are thoroughly crushed.

The ground sesame powder falls into the recess 11, and
It is sent by the feed blade 32 and swung out from the swung opening 33.

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 in which it is supported both upwardly and downwardly.
Since the fixed mill 17 is press-fitted and fixed to 6, 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 the eyes 16 and 17 can be aligned almost on the axis P of the rotary drive body 13. Twisting of the mortar 16 is effectively prevented.

Furthermore, even if a gap G exists between the outer circumferential surface 17 a of the fixed die 17 and the inner circumferential surface 15 a of the container 15 due to dimensional error, the annular shape protruding from the outer circumferential surface 17 a of the fixed die 17 Since the gap G is closed by the tongue piece 30, it is possible to prevent the sesame powder after the treatment from entering the upper surface side of the fixed mortar 17.

In the above embodiment, the annular tongue piece 30 is formed on the outer peripheral surface 17a of the fixed mortar 17, but the container 1
The same effect can be obtained even if it is formed on the inner circumferential surface 15a of No.5.

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 fixed mortar into this protrusion, the center alignment of both eyes becomes highly accurate. Since the abutting annular tongue piece is formed, grains will not enter between the fixed mortar and the container, making it possible to provide a sanitary electrically operated grain treater.
