Description

[Detailed Description of the Invention] This invention relates to the improvement of an electric grain preferential device suitable for sesame grinding, sesame grinding, etc.

Generally, the fixed molar of this type of molar has a synthetic resin preferential tooth pattern on its main surface consisting of a plurality of rib-like preferential teeth extending diagonally apart from each other in the radial direction, corresponding to the preferential tooth pattern of the rotary molar. It is integrally formed.

By the way, since each chain fracture tooth in this preferential tooth pattern has a low height compared to the wall thickness of the fixed molar itself, the resin concentrates in the molding, especially in the preferential teeth part, and as shown in FIG. The distal end surface 51 of the tooth 50 tends to deform into a concave shape after molding due to so-called resin sink.

For this reason, the preferential powder containing oil such as sesame seeds remains attached to the recessed portion 51 and cannot be removed, and if it is not cleaned frequently, it will rot and emit a foul odor.

If the wall thickness t of the fixed molar 52 is set thin, the concentration of resin on the preferential teeth 51 will be eliminated and sink marks can be suppressed, but conversely, in this case, it becomes difficult to maintain the strength of the fixed molar 51. There is.

Therefore, this invention solves the above-mentioned drawbacks by forming the same preferential tooth pattern on the main surface and the opposite surface of the fixed molar.

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
is projected, and at the open end of this recess 11,
A cup-shaped container 15 for supplying grains, which together with the drive unit case 1 constitutes a main body 14, is removably attached.

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. 19 (see Figure 2).

Reference numeral 20 denotes a rotary mill holder fixed to the tip 13 of the rotary drive shaft 8, and the rotary mill 16 is held by the holder 20 so as to be movable up and down, and is driven by the drive shaft 8. There is.

The fixed die 17 is fitted into a hollow protrusion 21 for a bearing formed in the center of the container 15 and positioned with respect to the rotary die 16, and is engaged with and disengaged from a rib 22 formed on the inner wall of the container 15. Possibly installed.

Of course, the fixed die 17 can also be attached to the drive part case 1 side.

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 so that the grains falling from the supply port 24 are fed between the preferential teeth 18 and 19 of the two eyes 16° 17.

As shown in FIG. 3, each preferential tooth 19 of the fixed molar 17 is formed in a rib shape and extends obliquely to the radial direction. 17
A preferential tooth pattern 26 is formed, and the same preferential tooth pattern 27 as this crushing tooth pattern 26 is also formed on the surface 17 b of the fixed molar 17 opposite to the main surface 17 a.

Reference numeral 28 denotes a feed blade that feeds the grain powder after the preferential treatment to the shaker port 29.

In the above configuration, for example, when sesame seeds are fed from the container 15 side through the input port 25 and between the preferential teeth 18 and 19,
The sesame seeds are crushed by the crushing action of these teeth 18 and 19.

The crushed sesame powder falls into the recess 11, and
It is sent by a feed blade 28 and swung out from a swung opening 29.

Here, the main surface 17a and the opposite surface 17b of the fixed die 17
Since the same preferential tooth patterns 26 and 27 are formed respectively, the fixed molar 17 can be formed with a thin wall, thereby suppressing resin whiskers during molding, and forming the preferential teeth 19 as shown in FIG. The distal end surface 19a can be formed flat, so that oil such as sesame powder is less likely to remain attached to the distal end surface 19a as in the past, and it is hygienic and does not emit any strange odor. Even if the fixed mortar 17 is thin, the main surface 17a and the opposite surface 17b
The preferential tooth patterns 26 and 27 are inclined in the same direction and intersect with each other to act as a frame, so that the mechanical strength of the fixed molar 17 can be effectively maintained.

Furthermore, if the tip edge of the preferential tooth 19 of the fixed molar 17 is worn out over time, the fixed molar 17 can be removed from the main body 14.
It can be removed from the side and the crushing teeth 19 on the opposite surface 17b can be made to face the rotary molar 16 side, making maintenance easier, and even when the fixed molar 17 is assembled, the main surface 17
Since there is no need to check between a and the opposite surface 17b, the assembly work becomes faster.

As described above, this invention can prevent hairs during molding without losing the strength of the fixed molar by simply forming the same preferential tooth pattern on the main and opposite surfaces of the fixed molar made of resin. It is possible to provide an electric grain preferential treatment device which can be easily assembled and maintained.
