Description

[Detailed description of the invention] This invention relates to the improvement of an electric grain preservative suitable for sesame grinding, etc. Specifically, it includes a rotary mortar and a rotary mortar holder that connects and holds the rotary mortar so that it can move up and down. The present invention relates to a structure that prevents grain flour after being treated from entering between the grain and the grain.

Generally, in this type of grain preferential device, a rotary mortar holder is fixed to the tip of a rotary drive shaft protruding into a recess at the upper end of the drive case, and a rotary mortar superimposed on the fixed mortar is connected to the holder. The rotary mill is elastically supported by a spring member interposed between the rotary mill and the holder so as to be movable up and down, and when the sesame powder etc. that have been preferentially treated by the fixed and rotary mill fall into the recess, Sesame flour and the like that have fallen into the recess are scraped off by feeding blades arranged circumferentially evenly on the outer circumferential surface of the holder, and are fed to an outlet formed at a predetermined location in the recess.

However, in the conventional type, as shown in FIG. 3, the outer circumferential surface 41a of the rotary mortar holder 41 rises vertically from its lower end, so the sesame powder etc. scraped up by the feed blades 42 are collected by the shaking outlet ( (not shown), it tends to creep up along the vertical outer circumferential surface 41a, and in that case, the outer circumferential inner surface 43a of the rotary mill 43
and the upper end outer peripheral surface 41 of the rotary mill holder 41 corresponding to this
The sesame powder may enter the interior through the gap G between the two 43 and 41 formed by b and block the expansion and contraction action of the spring member 44, or the gap G may become clogged and the rotary mill 43 may become clogged. This may adversely affect vertical movement.

In particular, the opposing surfaces 43a and 41b forming the gap G are arranged so as not to impede the vertical movement of the rotary mill 43 in the inclined position.
Since it is inclined inward, if the sesame powder creeps up, it easily enters the inside of the holder 41.

Therefore, this invention reliably eliminates the above-mentioned drawbacks by forming an annular sloped wall section on the outer circumferential surface of the rotary mill holder that expands upward from the lower end.

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 7 meshed with the reduction gear 6. The rotary drive shaft body 8 is rotated at low speed and high torque through the rotary drive shaft body 8.

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 chamber 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 provided. Part 1
3 protrudes, and the open end 14 of this recess 11
A cup-shaped container 15 for supplying grains is removably attached to the container.

16 is a rotary mill made of synthetic resin or the like disposed in the recess 11; 17 is a fixed mill made of synthetic resin or the like which is fixed to the side of the container 15 and superimposed on the upper surface of the rotary mill 16;
Each has preferential teeth 18 and 19.

Reference numeral 20 denotes a rotary mill holder fixed to the tip 13 of the rotary drive shaft body 8, and the rotary mill 16 is connected to the holder 20 via locking protrusions 21, 21 vertically provided on the lower surface of the rotary mill holder. It is held and rotated together with the holder 20 by the rotary drive shaft 8.

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

The fixed mortar 17 has an input port 25 formed in correspondence with the grain supply port 24 formed at the center of the bottom wall portion 23 of the container 15, and the grains that have fallen from the supply port 24 are collected therein. is fed between the preferential teeth 18 and 19.

As shown in FIG. 2, the outer circumferential surface 20a of the holder 20 has an annular inclined wall portion 2 that widens upward from the lower end.
6 is formed, and a feeding blade 27 for feeding grain powder is provided to protrude outward from this inclined wall surface portion 26.

Reference numeral 28 is a grain flour shaking port formed at a predetermined position in the recess 11, and 29 is a cap of the container 15.

In the above configuration, when grains such as sesame are fed from the container 15 to the preferential teeth 18 and 19 through the supply port 24 and the input port 25, the rotary mill 16 moves up and down according to the properties of the grains. It rotates to crush the grains, and then the hard crushed grain powder falls into the recess 11 and is fed to the shaker port 28 by the feed blade 27.

Here, when the feed blade 27 rotates while raking up the grain powder, the grains deposited on the front surface try to climb upward along the outer circumferential surface 20 a of the holder 20 . Since an annular inclined wall portion 26 is formed on the outer circumferential surface 20a, the inclined wall portion 26 prevents the above-mentioned creeping up. From the gap G to the holder 2
It is possible to effectively prevent grain flour from entering the inside of the holder 20, and therefore the vertical movement of the holder 20 can be maintained smoothly.

In the above embodiment, the annular inclined wall portion 26 is formed in a straight line, but it is not limited to this straight shape, and may be curved in an arc shape, for example, in which case the creeping up of grain flour is prevented. This can be prevented even more reliably.

As described above, this invention has a simple structure in which an annular sloped wall section is formed on the outer circumferential surface of the rotary mill holder, expanding upward from the lower end, and effectively prevents grain flour from entering the holder. It is possible to provide an electric grain preferential device that can
